An operating cable composed of an outer tube which is made cylindrical through the winding operation of a band-shaped steel-sheet in a spiral shape, and an inner wire which is inserted into the outer tube and is guided by the outer tube. A groove which is open on at least the winding inner side of the band-shaped steel-sheet is provided, in the band-shaped steel-sheet, along the length direction. A band-shaped liner is engaged into the groove to project from the winding inner side of the band-sh...

This invention relates to operating mechanisms for hydraulic control systems and it is an object of the invention to provide an operating mechanism which is self-locking. The mechanism includes a bar which is slidable in a channel, one face of the bar being cut away to provide two inclined surfaces. Rollers are retained by springs in the spaces between the inclined surfaces and one side of the channel. A plate is also located between the bar and the said side of the channel and a control member ...

Operating means comprise an air cylinder and a hydraulic cylinder mounted in axial alignment. A rod passes through both cylinders, and a piston in the air cylinder is mounted on the rod. A hollow member which is positioned about the rod passes through the hydraulic cylinder and extends from the ends thereof, and a piston in the hydraulic cylinder is mounted on the hollow member and divides the interior of the hydraulic cylinder into first and second chambers. First and second axially adjustable ...

An operating device selectively connects and disconnects a first operating system with a second operating system. The first operating system has a frequently used operating piece, such as a brake lever. The second operating system would conventionally have an infrequently used operating piece, such as a starting lever. Switching means selectively connects and disconnects the first and second operating systems so that the systems may be operated simultaneously or separately by the operation of a ...

A method of operating a fluidized bed system, typically as a combustor system for power or steam generation by burning high-sulfur coal, which comprises forming an entrained fluidized bed in a first space region containg a first solid bed particle component, such as a hematite ore containing over 90% Fe.sub.2 O.sub.3, or limestone, forming in a more limited space region within the first region a dense fluidized bed containing a second solid bed particle component, such as larger particles of the...

An operating table for lower portions of the human body comprises a single bar that extends lengthwise from the table and carries supports for the legs and feet on either side of the bar. The supports are adjustable, those for the feet being universally mounted at the ends of a pair of arms that extend swingably from both sides of the bar on a holder that is movable lengthwise of the bar. The bar itself is movable transversely of its length, from side-to-side of the table, by means of a crank-op...

An operating table comprises a patient rest or support structure which is mounted at a rolling bearing, i.e. a bearing associated with the rolling motion of the patient rest or support structure. The axis of this rolling bearing corresponds with a rolling or roll axis and defines a predetermined angle with the patient rest or support structure, so that the extension of the axis of the rolling bearing, subsequent to intersection thereof with the plane of the patient rest or support structure at a...

An operating table structure in which the operating table comprises a plurality of sections adjustable relative to each other, and in which the control means for controlling the adjustment of said adjusting means are arranged on pivot arm means pivotally connected to the upper portion of the operating table structure.

An operating switch panel, such as for an audio equipment tuner, utilizes a metal plate which is divided into a plurality of operating parts by simultaneous etching from both sides. Connecting parts remain between individual operating parts. Thin hinges are formed on the operating parts by etching from the back surface of the metal plate, dividing each operating part into two stationary and movable parts. The stationary parts are connected to each other through the connecting parts. Display part...

An operating table including a support structure and an elongate table top mounted on the support structure. The table top is composed of four relatively movable sections arranged in edge to edge relationship with the adjacent edges of each two adjacent sections extending transverse of the longitudinal axis of the table top and each section being movable relative to its adjacent section about an axis also extending transverse to that longitudinal axis. One of the sections forms a first transfera...
