Abstract: The present invention provides novel active materials which reversibly store hydrogen under conditions which make them exceptionally well-suited for electrochemical applications. These active materials have both novel compositions and structures. A first group of active material compositions incorporate the elements of titanium, vanadium, and nickel. A second group adds zirconium to the first group of active materials. A preferred third composition group adds chromium to the first group of active materials. These materials may be single or multiphase combinations of amorphous, microcrystalline, or polycrystalline structures. Preferably, these materials have a multiphase polycrystalline structure. Methods of reducing the size or of sizing these materials, as well as other hydride-forming alloys, also are provided. Methods of preparing the inventive hydrogen storage materials and fabricating electrodes from these active materials are contemplated. Electrochemical cells and batteries assembled with the inventive electrodes provide significantly improved capacity and cycle life.

Abstract: TRANSMISSION LINE RECEIVER/TRANSMITTER          By Robert L. Spiesman ABSTRACT         A transceiver for applying signals to and receiving signals from a transmission line through a coupling transformer having a transmission line winding connected to the transmission line and a transceiver winding.  A transmitter circuit is connected to the transceiver winding to apply Manchester encoded digital data signals having a high frequency to the transmission line.  The transmission line can, at any instant in time, also be carrying data signals which are applied to the transmission line by other transceivers.  However, only one transceiver transmits such data signals at any one time.  At the same time as the transmission line may be carrying data signals, it can also be carrying timing signals which are applied to it by a timing driver circuit.  The timing signals have a significantly lower frequency than the data signals and a quasi-sinusoidal wave form.  The transceiver includes a first receiver which is connected across the transceiver winding and which amplifies and reshapes any data signals present across the transceiver winding and produce such signals as the data signal output of the transceiver.  A second receiver is also connected across the transceiver winding.  This second receiver reconstitutes the received timing signals included in the signals induced or present across the transceiver winding so that the output of the second receiver is a square wave timing signal, the frequency of which is that of the quasi-sinusoidal timing signal received.

Abstract: ABSTRACT     The present invention comprises methods and apparatus for controlling the speed of a motor for a piece of ice slab refrigeration equipment, in response to variations in thermal load on the ice slab.  The control apparatus comprises thermal load sensing means and motor drive means.  The thermal load sensing means detects variations in the thermal load on the ice slab and generates an output signal correlatable with such variations.  The motor drive means is operatively coupled to the thermal load sensing means and is connectable to the motor and drives the motor at various speeds correlatable with the variations in ice slab thermal load. The control apparatus of the present invention is particularly adapted to control the speed of an alternating current induction motor of a centrifugal brine pump motor.  The thermal load sensing means preferably comprises temperature detecting means such as a resistance temperature detector for detecting the fluctuations in the brine temperature, and drive control means such as a signal transmitter for generating a reference signal for input into the motor drive means, which preferably comprises a variable speed drive.          Incorporating the control apparatus of the present invention into existing ice rink refrigeration systems is expected to drastically reduce operating costs.

Abstract: S P E C I F I C A T I O N            'Improvements in or relating to cutting elements for rotary drill bits' ABSTRACT OF THE DISCLOSURE           A method of producing a thermally stable poly-crystalline diamond compact comprises placing in a high pressure/high temperature apparatus a mass of poly-crystalline diamond particles, the mass having a front face and a rear face, and a mass of catalyst metallic material, and then subjecting the masses to high pressure and temperature such that the metallic material infiltrates the mass of diamond particles so as to form, on subsequent cooling, a solid composite compact.  The grain size and/or packing density of the polycrystalline diamond particles is varied between said front face and rear face in such manner that, in the finished compact, material nearer the rear face is less wear resistant than material nearer the front face, so that the compact is self-sharpening in use.  Alternatively or additionally, the wear resistance is varied by including an additive with the diamond particles, the proportion of the additive varying between the front face and rear face.

Abstract: ABSTRACT            An improved method of severing a large area of an amorphous semiconductor device material into smaller area devices.  The material includes an amorphous semiconductor body disposed between an electrically conductive substrate and a transparent electrically conducting coating.  The transparent coating is brittle and upon severing can leave electrically conducting shards that short circuit the substrate to the coating.  This problem is overcome by supporting the coating, either bare or with a protective member, which may be resilient, and applying a shearing force to the substrate.  Cardboard, paper and polymers may be used as protective members.

Abstract: SEISMIC IMPULSE SOURCE TRANSDUCER                 ABSTRACT OF THE DISCLOSURE       A spark discharge acoustic pulse transducer for borehole operation provides an insulating ceramic barrier which contains a small cross-section aperture separating two bodies of electrolyte through which the two zones of liquid make contact.  An electrical arc discharge is caused to occur through the aperture to produce a transient pressure pulse and associated acoustic pulse which is coupled to the geologic formation at the borehole wall.  The specific shape and geometry of the aperture channel in the insulating barrier being exponentially shaped provides a means for controlling the waveform and frequency spectrum of the acoustic pulse.          The transducer has an elastic outer housing and an elastic inner housing with hydraulic fluid between the inner and outer housings.  The pressure of the hydraulic fluid may be increased to expand the outer housing against a borehole prior to a spark discharge.  The transducer is also provided with a system for venting gas produced as a result of the spark discharge.
