The history of Western wind instruments In the field of organology, or the study of musical instruments, the name Curt Sachs looms so large that, despite the studies undertaken since his death in , no one has yet achieved his eminence. The origins of musical instruments extend to prehistoric times, and frequently only fantastic legends survive; yet, by combining information from anthropology, history, and linguistics, Sachs made discoveries, developed theories, and drew conclusions that have stimulated much research in and given purpose to the entire field. Much of the following material leans on his research and perception, with slight modification to reflect more recent discoveries. Early history The sources of information on the early history of musical instruments are often nebulous. Among the few instruments that have survived from the prehistoric period are bone end-blown flutes with notched mouthpieces and finger holes that show technical skills and acoustical knowledge. Cave paintings and rock carvings show an impressive variety of instruments.

As lighting equipment is so robust choice is further complicated, in that in addition to the range in today’s catalogue, many earlier models are still in use. However lighting instruments group into families and it is convenient to consider our requirements in terms of what each family offers in terms of beam size, beam shape, and beam quality. Floods Floodlights are the simplest of all theatre luminaires, comprising of little more than a lamp and reflector in a box that can be panned from side to side and tilted up and down.

As they have no lenses, the output characteristics of the floodlight are determined solely by the reflector and lamp type. The light is therefore suitable for lighting skies and cloths, it is not selective enough for lighting actors. Floodlights are available in two variations – symmetric and asymmetric Traditional symmetrical theatre floods use ‘domestic’ shaped lamps in a bowl shaped reflector, giving a uniform distribution of light in all directions.

As the delta-V for a mission goes up, the amount of propellant required goes up exponentially (or looking at it another way: the amount of payload shrinks exponentially).Large amounts of propellant are expensive, but the higher the mass-ratio the higher the likelihood that the spacecraft will not be resuable.

In a free market society, the competitive system demands that every product be produced at the highest possible quality standards while maintaining the lowest possible cost. To achieve this goal, companies must look to the engineering departments within tool manufacturing companies to develop the proper processes and equipment to bring about the best product or tool design. What is a Broach Tool Designer? A broach tool designer is a manufacturing engineer who is concerned with the creation and implementation of the broach tools and associated equipment needed to provide the metal working industry with increased manufacturing productivity while, at the same time, reducing manufacturing costs.

Broach tool design is a specialized area of manufacturing engineering which comprises the analysis, planning, design, manufacture, and use of tools, methods, and procedures necessary for manufacturing productivity. In order to perform these duties, the broach tool designer must have a working knowledge of machine shop practices, tool making methods, machine tool design, manufacturing procedures and practices, as well as the more conventional engineering disciplines of planning, designing, engineering graphics and drawing, and cost analysis.

Responsibilities and Requirements of the Tool Designer? Broach tool designers are responsible for a wide variety of special tools. Although most of these tools are an end product, some will be designed merely as aids for manufacturing. The broach tool designer must be familiar with the following insofar as they affect the design of broach products and other special cutting tools: Broach cutting tools Broach tool pullers and holders Metalworking fluids and coolants Gages and other measuring devices Nuts, bolts, and various other fasteners Metallurgy and steel composition Machine tool design Electronics and computers The current size of the company and the number of tool designers will determine the exact duties of each designer.

If many tool designers are employed, each designer may have an area of specialization, such as punch and die design, layout, programming, etc.

The Kinderhook Plates Readers should note that today, these items are either lost or verified forgeries. The Manual’s Kinderhook section defends Joseph Smith’s partial translation. Its editors suggest that the testimony of Wilbur Fugate, who admitted creating the plates as a hoax, must be false, primarily because only he out of the three “discoverers” blew the whistle on the forgery. Moreover, the editors express suspicion of Fugate because he waited 36 years to confess his part in the supposed hoax.

Why, they ask, did he not confess his supposed hoax immediately after the release of Joseph Smith’s initial translation? Kimball, the Cchurch also published missionary pamphlets in the s with the story of the Kinderhook Plates—apparently to be used as a conversion tool. After penetrating about eleven feet the workers came to a bed of limestone that had been subjected to the action of fire.

They removed the stones, which were small and easy to handle, to the depth of two feet more, when they found the skeleton. This was evidently a burial chamber, as with the bones, which appeared to have been burned, was found plenty of charcoal and ashes. From this fact it is evident that some of the mounds are of very ancient date, as it is not supposable that this man would be the only one of his race and nation to be buried in this manner. We also suggest that this colony of Egyptians may have originated the style of architecture in this country in which so many find resemblances to the Egyptian, and which is specially characterized by the erection of vast truncated pyramids.

History[ edit ] The first pantograph was constructed in [1] by Christoph Scheiner , who used the device to copy and scale diagrams, but he wrote about the invention over 27 years later, in “Pantographice” Rome By changing the positions of the arms in the linkage between the pointer arm and drawing arm, the scale of the image produced can be changed. Diagram illustrating the principles used by William Wallace’s eidograph In , Professor William Wallace — invented the eidograph to improve upon the practical utility of the pantograph.

Drafting[ edit ] The original use of the pantograph was for copying and scaling line drawings. Modern versions are sold as toys. By adjusting the needles different enlargement or reduction ratios can be achieved. This device, now largely overtaken by computer guided router systems that scan a model and can produce it in a variety of materials and in any desired size, [5] was invented by inventor and steam pioneer James Watt — and perfected by Benjamin Cheverton — in

Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity.

There are two types of hook-up drawing: Process Hook-Up This hook-up drawing contains typical installations for instrument which connects to the process Pneumatic Hook-Up This hook-up drawing contains typical installations for instrument which requires instrument air such as control valve, actuated valve Reference drawing: A good designer can also read whether the instrument tapped in gas service or liquid service.

Installation detail specification will also specify items that should be utilized and factor that should be considered in one installation The purpose of Instrument Hook Up Drawing As stated earlier, information of the requirement of bulk material is stated for installation on each sheet hence the bulk material required for the whole drawings could be summarized and tabulated in a document named Material Take Off. During project construction phase, this drawing is also referred as a guidance of how to install the instrument properly.

Karen Cuneo Ramirez is one of my favorite person when it comes to practical music theory http: ChuckO You seem to know theory but it seems odd that you are looking at actual chords and their frequency and not the chords relationship to the scale which would seem to me to be more relevant. Although it would be interesting if hit songs in the key of C were prevalent especially if the singers tended to sing in a particular range.

ChuckO By range I mean octave.

A harpoon is a long spear-like instrument used in fishing, whaling, sealing, and other marine hunting to catch large fish or marine mammals such as whales. It accomplishes this task by impaling the target animal and securing it with barb or toggling claws, allowing the fishermen to use a rope or chain attached to the butt of the projectile to catch the animal.

So Square Enix and Disney walk into a bar The series is well-known for its incredibly bizarre premise and increasingly complicated plot. Sora is a young boy living a peaceful but boring life on an island with his best friends Riku and Kairi. This is until the day his world is engulfed by The Heartless , an eldritch species that feed on the hearts of innocent people and literally consume entire worlds. Sora is sucked through a portal and winds up in Traverse Town, a crossroads world that has become the refuge of those who have lost their worlds to the Heartless.

As he begins to search for his missing friends, Sora is granted the mysterious Keyblade: With the aid of Donald Duck and Goofy, two royal knights searching for their missing king, Sora must travel to all of the different worlds in The Multiverse and use the Keyblade to lock them safely away from the Heartless and those who plot to use the Heartless to further their own ends. Meanwhile Riku, having also ended up in Traverse Town, becomes obsessed with rescuing Kairi at all costs and is tempted by the same power of darkness that Sora is trying to seal, setting up the two best friends for a fateful confrontation.

As Sora and Riku grapple with their newfound powers and responsibilities, an ever-expanding mythology begins to unfold around the legendary Kingdom Hearts: The first game in the series, detailing the world-hopping adventures of Sora, Donald and Goofy as they search for their missing friends and a solution to the darkness invading the worlds.

At lunar takeoff, this tanker would mass tons, but since it is taking off in lunar gravity, it would effectively weigh only about 62 tons. The composite propellant tanks, similar to what will be used for the BFR, would probably mass only 20 tons, leaving 2 tons for the engines, 2 tons for the landing legs, and 6 tons for the rest of the structure, including the cryo-coolers, sunshade and power system. This provides a structural mass fraction of 8. At this point, we do not know the actual cost of the lunar propellants as delivered to the tanker at the lunar base, including the vehicle development costs, but finally we can compare the relative mass of the delivery propellants.

Assuming that we have not underestimated the tanker mass, the delivery propellant mass from Earth to LEO to L1 is
