Title: Closed cycle energy conversion using water or compressed air - uses output from water-wheel driven alternator to pump spent water for re-use to drive water wheel
IPC: H02K53/00
Filed: 1983-04-18
Abstract: The unit uses water or compressed air to drive a turbine. The turbine is mechanically coupled to an alternator which generates 220 Volt alternating current. The alternator output is used to drive a pump which is used to raise the spent water from the turbine to a suitable head for it to be re-circulated and directed once again onto the water turbine. In addition to the closed cycle described above, a jet of water derived from the town water supply can be used to supplement the power input to the water turbine.

Abstract: ABSTRACT    This patent describes the catalytic promotion of the reaction of oxirane-containing compounds with carboxylic acid compounds at high, ambient, and low temperature.  Specifically, this  patent describes the method of reacting oxirane-containing compounds with carboxyl-containing compounds, preferably at temperatures at or around ambient in the presence of active chromium III tricarboxylate salts which have unoccupied coordination sites.  More specifically this patent describes the preparation of catalytically active chromium III-tri-carboxylates from normally catalytically inactive chromium III-tri-carboxylate hydrates.  These compounds are powerful catalysts for the reactions of oxirane compounds with both organic carboxylic acids and cyclic primary imides.

Abstract: Abstract of the Disclosure Disclosed herein is a cutter for a rock bit that has an interior bearing race area carburized by pack car-burization methods to achieve a high carbon content for extreme hardness.  The exterior of the cutter is carburized also, but to a lesser degree, to avoid brittleness in the tooth area.  The differential carburizing is accomplished by gas carburizing the exterior while simultaneously pack carburizing the interior.  Conventional heat treatment for hardening follows.  This results in a cutter having a bear-ing area much harder than the exterior, giving a long bear-ing life and reducing tooth breakage.

Abstract: METHOD AND APPARATUS FOR PRINTING SEGMENTED CHARACTERS            ABSTRACT OF THE DISCLOSURE A printer of the dot matrix type for printing, single, double and triple sized characters.  Normal sized characters are printed in the con-ventional fashion.  Double and triple sized characters are printed through a segmented technique in which segments of the double and triple sized characters are stored within readable memories (ROMS).  For double sized characters which occupy two adjacent character lines, the segmented patterns for the upper portions of the characters are printed along the first normal sized character line.  The lower half of the double sized characters is printed on the next adjacent character line by selection of the appropriate segmented patterns.  Triple sized characters are printed in a similar manner, utilizing three lines of conventional sized characters.  The same technique may be employed to create other graphic patterns of 1 to N lines, where N is a real integer equal to or greater than 2.  The technique permits the utilization of either unidirectional or bidirectional printers.

Abstract: A DIGITAL TIME-DIVISION MULTIPLEXING SYSTEM by Alvin L. Pachynski, Jr.                      ABSTRACT OF THE DISCLOSURE           A time-division multiplexing system wherein N parallel digital signals having an average bit rate of f1 are interleaved by a multiplexer to form a single composite line signal of bit rate f2, where f2 > Nf1.          Prior to multiplexing, signal gaps having a predetermined duration and having a fixed repetition rate are inserted into each of the N parallel signals.  Adding gaps to each digital signal permits the bit rate between gaps to be increased to f2/N, a submultiple of the composite line signal bit rate.  The gap duration and their occurrence is such so as to maintain the average bit rate of each digital signal at f1.  Each digital signal with the added gaps is then interleaved to form the composite line signal having the desired bit rate of f2.  The interleaved gaps form empty time slots in the composite signal into which one or more signaling bits are added.  Some of the added signaling bits carry framing information to enable the multiplexer and demultiplexer to maintain synchronism during signal transmission.  Thus, a composite higher-rate digital line signal, consisting of interleaved information bits and signaling bits, forms the time-division multiplex signal suitable for transmission over a single digital transmission path.  The N parallel digital signals are recovered at the demultiplexer by sequentially selecting each information bit associated with a particular digital signal.

Abstract: EXPOSURE DEVICE FOR A XEROGRAPHIC COPYING MACHINE       ABSTRACT OF THE DISCLOSURE         An exposure device for a copying machine has a light source unit, and a rail unit for supporting the former rigidly mounted to the machine. The light source unit includes an exposure lamp, a heater for heating the lamp, and a control sensor for energizing the heater until the lamp reaches a proper temperature.  The rail unit includes a plate having an elongated exposure aperture therein, an elongated reflecting mirror along one side of the aperture, and a guide rail spaced from the plate along the other side of the aperture.  A particular positional relationship must be maintained between the optical system and photoreceptor of a copying machine, the exposure lamp, and the exposure aperture.  The present invention allows the light source to be mounted to and dismounted from the machine without disturbing this relationship.  This is effected by providing (1) a projection on the light source unit which extends through the space between the plate and guide rail as the light source unit is slid along the plate and guide rail to limit the lateral movement of the light source unit, and (2) a spring which serves to stop the light unit when it reaches the proper position and to bias it into con-tact with the plate and guide rail.
