In a high temperature/high pressure vessel for treating a workpiece placed in the interior of the vessel at a high temperature and a high pressure wherein piano wire is wound under tension round an outer periphery of a cylindrical body to apply a compressive residual stress to the cylindrical body and axial openings of the cylindrical body are tightly closed with upper and lower lids so that the lids can be disengaged from the openings, the cylindrical body is constituted as a two-layer cylindri...

A telecommunications and data connector with a connector first side assembly having a first side base portion formed of plastic and defining a plurality of grooves. The connector first side assembly also includes a first side plurality of contact elements. Each of the contacts extend from a wire end toward an assembly connection end. Each of the first side contact elements is movable between a contact position, and a non-contact position. A connector second side assembly is provided which is sub...

A high resolution high speed comparator featuring a differential amplifier that is coupled to two high amplification output stages. The output stages assist in rapidly amplifying input signals, yet do not interfere with comparator offset cancellation. In a preferred embodiment the comparator is made up of three stages, an input sampling network, a first amplifier stage, and a second amplifier stage, with the high amplification output stages being located in the first amplifier stage.

The production capacity of a conventional high pressure feeder having a pocketed rotor with a slotted screen at the low pressure outlet port is significantly increased by constructing the screen so that its arcuate bars have a width much less than normal, and thus a much greater open area of the screen is provided. Structural integrity is maintained by providing a reinforcing bar extending transverse to the arcuate screen bars, typically attached at the convex mid-point area. The screen is forme...

A quantizer (20) includes a series of folding amplifiers (22) coupled by a binary weighted resistor ladder (44, 46, 48, 50). Each folding amplifier (22) includes resonant tunneling diodes (34, 36, 38, 40) to control switching of a transistor (32). The output of the folding amplifier (22), as determined by the switching state of the transistor (32), is compared to a reference voltage (V.sub.REF) by a comparator (42). The comparator (42) determines the correct output state of the folding amplifier...

A backlight comprising a serpentine fluorescent tube nested in a uniquely shaped reflector. Much of the light emitted from the tube is directly emitted to a bounded image plane. The reflector reflects a substantial portion of the rest of the light emitted by the tube to the image plane in such a manner that a very bright and uniform image is formed at the image plane.

The present invention locates the primary winding of a transformer in a configuration where it substantially surrounds the secondary winding of the transformer in order to enhance the efficiency of the electromagnetic coupling. High magnetic permeability material surrounds portions of the primary winding of the transformer. The transformer is designed to efficiently operate at frequencies of approximately 50 kilohertz. In one preferred embodiment, the primary winding of the invention is formed o...

A high hat includes a ground supported stand with a vertical hollow tube through which a cymbal rod is operably mounted. A lower cymbal is mounted on the upper end of the tube with an upper cymbal connected to the upper end of the cymbal rod such that vertical movement of the cymbal rod will cause the upper and lower cymbals to contact one another for a percussive sound. A spring is connected to the cymbal rod to bias the rod into its upper position, wherein the upper cymbal is spaced upwardly a...
