The cylinderdesk is a desk that resembles a Bureau Mazarin or a writing table equipped with small stacked shelves in front of the user s main work surface, and a revolving cylinder part that comes down to hide and lock up the working papers when the desk is not in use. File Cylinderdesk David Roentgen M nchner Residenz DSC07473.JPG thumb 300px Like the rolltop desk , which was invented much later, the cylinderdesk usually has a fixed work surface the paperwork does not have to be stored before the desk is shut. Some designs, however, have the capacity to slide the desk surface out a few inches to expand the available work area. The cylinderdesk is also called bureau Kaunitz , as it was allegedly introduced in France in the first half of the 18th century by Wenzel Anton von Kaunitz , then the ambassador of the Habsburg Habsburg Empire to the French court. Regardless of the authenticity of its origin, the French court adopted this type of desk with great enthusiasm. The difficulty of producing wooden cylinder sections which would not warp over the years ensured that such desks were reserved for the rich and the very rich. A few variants of this form have slats instead of a one piece cylinder section. Image Cylinderdesksideinjpeg20031129.png The most famous cylinderdesk, and perhaps the most famous desk of all times is the Bureau du Roi manufactured for the French royalty in the 18th century.

Image Rolltop desk.JPG thumb 250px Typical rolltop desk A rolltop desk is a 19th century reworking of the pedestal desk with, in addition, a series of stacked compartments, shelves, drawers and nooks in front of the user, much like the bureau gradin or the Carlton House desk . In contrast to these the compartments and the desktop surface of a rolltop desk can be covered by means of a tambour consisting of linked wooden slats that roll or slide through slots in the raised sides of the desk. In that, it is a descendant in function, and partly in form, of the cylinderdesk of the 18th century. It is a relative of the tambour desk whose slats retract horizontally rather than vertically. Image Rolltopdesksideinjpeg20031124.png thumb left 250px Unlike the cylinderdesk, the rolltop desk could be mass produced rather easily since the simple wooden slats could be turned out very fast in a uniform way. In contrast, the wooden section of a cylinder had to be treated with great pains to keep its form perfectly over time, lest it warp or bend, and make it impossible to retract or extend. The wooden slats of the rolltop s tambour were usually joined together by being all attached to a cloth or leather foundation, and were thus less influenced by the problems which plagued the cylinderdesk. The rolltop desk was the mainstay of the small or medium sized office at the end of the 19th century and the beginning of the 20th. It gradually fell out of favor with the introduction of the steel desk and the coming of greater quantities of correspondence and other documents, which made the small ... expensive especially if the wood used is expensive.

A spinet desk is an antique desk form which has the exterior shape of a slightly higher than usual writing table , fitted with a single drawer under the whole length of the flat top surface. The spinet desk is so named because when closed it resembles a spinet , a musical instrument of the harpsichord family. This single drawer, however, is a dummy. It is a hinged panel which is meant to be folded in, at the same time as half of the hinged top surface is folded back on to the top of the other half, revealing an inner desktop surface of normal height, with small drawers and pigeonholes in the back. In certain spinet desks the inner desktop surface can be drawn out a few inches, adding working space. Image Spinetdeskfrontinjpeg20040131B.png thumbnail right 700pix Front of spinet desk, closed Image Spinetdesksideinjpeg20040131B.png thumbnail right 700pix Side of spinet desk, partly open The image of the front of the spinet desk shows it in a closed position while the image of the side shows it in a partly open position, just before the hinged mobile part of the top is placed on the fixed part of the top. By this capacity of hiding or revealing the main working area the spinet desk could be said to be a smaller, less obtrusive cousin of the rolltop desk and the cylinderdesk .

The hydraulic pressure created by moving a piston inside the bore of the master cylinder toward the slave cylinder s compresses the fluid evenly, but by varying the comparative surface area of the master cylinder and or each slave cylinder, one will vary the amount of force and displacement applied to each slave cylinder relative to the amount of force and displacement that was applied to the master cylinder .

Orphan date December 2007 A wheel cylinder is a component in a drum brake system. It is located in each wheel and is usually at the top, above the shoes. Its responsibility is to exert force onto the shoes so they can contact the drum and stop the vehicle with friction . What connects these wheel cylinders to the shoes are usually small rods shaped like a birds beak. It is very similar to a master cylinder and functions in pretty much the same way, consisting of just a simple little plunger on the inside. On older vehicles these will begin to leak and hinder the performance of the brakes, but are normally inexpensive and easy to replace. The wheel cylinder consists of a cylinder that has two pistons, one on each side. Each piston has a rubber seal and a shaft that connects the piston with a brake shoe. When brake pressure is applied, the pistons are forced out pushing the shoes into contact with the drum. Wheel cylinders must be rebuilt or replaced if they show signs of leaking. automotive part stub Category Brakes ... more details

Cylinder 1024 is the first cylinder disk drive cylinder of a hard disk that was inaccessible in the original IBM PC compatible hardware specification, INT 13H interrupt 13h , which uses cylinder head sector addressing. At boot time very old BIOS of many PCs could only access the first 1024 cylinders, numbered 0 to 1023 as CHS addressing only defines 10 bits for the cylinder count 2 10 1024 . This was a problem for operating system s on the x86 platform as the BIOS must be able to load the bootloader and the entire kernel computer science kernel image into memory. Both of these must, therefore, be located on the first 1024 cylinders of the disk. Older versions of Microsoft Windows resolved this by necessitating that the operating system was installed to the first partition. Because of this bug, users of the Linux operating system have traditionally created a tt boot tt partition to reside within the first 1024 cylinders of the disk, containing little more than the Kernel computer science kernel and bootloader.
