Abstract: A cam-switch assembly is disclosed in which the individual cam-switches are individually adjustable with respect to the registering cams. The cam-switch assembly comprises a support bracket having at least two parallel end walls supporting a pivot rod and a cam shaft. The cam shaft functions to support a plurality of cams coaxially mounted thereon. A plurality of cam switches are provided with each cam-switch including a cam follower responsive to a respective cam for actuating the switch. A plurality of mounting brackets are pivotally mounted on the pivot rod with each bracket supporting a respective cam-switch by means of the pivot rod and properly positioned anchor which is an integral part of the mounting bracket. Each mounting bracket includes a cantilevered end formed in a U-shaped configuration with one leg of the "U" having a slot formed thereon for adjustably receiving a locking screw. The other leg of the U includes a threaded bore for securedly receiving a locking screw.

Abstract: A method for controlling the output torque condition of an induction motor includes the steps of generating a slip frequency in the motor proportional to the desired output torque condition while simultaneously establishing the magnitude and phase displacement of the stator current at preselected values. The invention also obtains the speed control of self excited alternating current motors.

Abstract: A fitting assembly is disclosed for connection to the ends of flexible tubing. The fitting assembly comprises a first and second element and a sleeve. The first element includes a threaded bore and a plurality of flanged tines extending axially therefrom. The flexible tubing is adapted to be threaded through the bore of the first element until a portion of its end extends alongside and beyond the tines. The second element includes a bore having interior annular ridges formed on the interior surface thereof for receiving the flanged tines of the first element. The second element also includes an annular shoulder located on the sidewall of the bore. The sleeve is cylindrical in construction and includes an enlarged end. The sleeve is adapted to fit snugly within the end of the flexible tubing prior to the interconnection of the first and second elements. After the first element is threaded onto the tubing and the sleeve is inserted therein, the first and second elements are brought together for connection.

Abstract: An anti-friction device for use under hostile conditions such as high temperature or nuclear radiation environments or for use under sustained impact loading. The device comprises two components: first, a fibrous, non-metallic substrate which is capable of withstanding hostile conditions such as high temperatures, high nuclear radiation or sustained impact loading, and second, a lubricating medium carried by and substantially permeating the entire fibrous substrate. When the device is disposed between two members, the members will be capable of moving relative to one another due to the relatively low coefficient of sliding or rolling friction at a surface between the members.

Abstract: An X-ray tube is disclosed having a cathode and rotating anode located within a glass envelope. The rotating anode comprises an annular disc forming the target area. The disc is integrally connected to a stem which in turn is connected to a hollow cylindrical rotor. The interior of the cylindrical rotor extends over the anode support shaft and bearing structure. The anode shaft supports the rotor, stem and anode disc and is integrally connected thereto via a thin-walled, cup-shaped member made of a low heat conductive metal. The interfaced connections with the cup-shaped element are accomplished through minimal contact surfaces to provide a thermal barrier against the heat energy generated in the anode structure, thereby preventing the heat energy from passing through to the shaft and bearing structure.

Abstract: This invention relates to dies and the method for making dies for rolling threaded fasteners having conical or truncated conical ends. The face of each of a pair of dies which contacts the workpiece includes a first generally planar surface having a plurality of parallel ridges disposed thereon. A second generally planar surface having ridges thereon for threading the conical or truncated conical end is disposed on the face at an angle with respect to the first generally planar surface. The face on which the two generally planar surfaces are disposed is normally generally rectangular and elongated in the direction of relative movement between a pair of dies. The intersection of the two generally planar surfaces and each groove or ridge disposed on each such surface is positioned in parallel realtionship to every other ridge or groove and the intersection of the first and second generally planar surfaces.
