Granted: 1991-09-10
Abstract: ELECTRONIC BINGO CARD MANAGER                         Abstract An electronic device for managing at least two bingo cards. The device has stored standard card configurations which correspond to physical cards which have been selected by a player.  Also stored are standard winning patterns.  The processor compares "called" numbers with card configurations which correspond to the physical cards being played by the user.  The device alerts the player when a winning card occurs.  When "padded" paper cards are used, the device generates each succeeding game board.

Abstract: Metal  values  in  non-ferrous  metallurgical  slag  are recovered by gently agitating the slag  in contact with matte  using  stirring  energy dissipation rates  insuffi-cient to emulsify slag in matte.   These low agitation rates conserve energy by reducing cooling of the charge, especially by reducing the period required for the slag and  matte  to  separate  out  into distinct  layers  after agitation,  and  the  preferred  energy dissipation  rates increase the efficiency of the value metal recovery and avoid or reduce impairment of the reducing capabilities of the matte and hence its capabilities for reducing and collecting oxidized value metal species from the matte by avoiding or reducing oxidation of the matte as a result of dispersal of the oxidation-protective overlay of slag and  contact  of  the  matte  with  the  ambient  oxidizing atmosphere.

Title: High voltage dc power supply
Inventor: GUNN BRADLEY R

Granted: 1992-10-13
Abstract: HIGH VOLTAGE DC POWER SUPPLY                 ABSTRACT OF THE DISCLOSURE        A DC power supply for a traveling wave tube having cathode, collector and helix electrodes responds to a DC power source and a high frequency switching source.  A switch controlled by the switching source is opened and closed at a fixed frequency and variable duty cycle determined by the helix-cathode voltage.  A flyback choke is connected to the switch and DC power supply so current flows between the power source via the choke to the switch and a series resonant circuit while the switch is closed. First and second capacitors in separate branch circuits of the resonant circuit are, respectively connected to first and second AC to DC converter and voltage multiplier stacks; each multiplier in the stacks includes a pair of branches with oppositely poled plural signal switching diodes and a capacitor.    The cathode and helix are respectively connected to output terminals of the first and second stacks, while the collector is connected to a terminal between the first and second stacks.   The resonant circuit is connected with the switch, flyback choke and voltage multipliers so that while the switch is closed a half-wave rectified current hump at the resonant circuit resonant frequency flows in the resonant circuit and a ramping current having a first polarity direction flows in the choke.   A ramping current having a second polarity direction flows in the choke and resonant circuit while the switch is open.

Abstract: ABSTRACT          A  method  of  programming  a  programmable  hearing  aid  is disclosed   The programmable hearing aid has a serial data interface for receiving data transmissions,  a decoder for decoding data transmissions, a program memory which stores program data values received via the serial interface, and read control logic that transmits the program data stored in the program memory when the decoder detects the receipt of a predefined read signal   Programming begins with the sending a set of program data values to the programmable hearing aid, preceded by a predefined write signal.   The hearing aid automatically mutes or inhibits its operation upon receiving the write signal   A first checksum value corresponding to the program data values sent to the programmable hearing aid is calculated.   Next, the data stored in the hearing aid is checked by sending a predefined read signal to the hearing aid,  causing the hearing aid to transmitting the program data stored d in its program memory   A second checksum value corresponding to the program data transmitted by the hearing aid  is  calculated and compared with the  first  checksum value.  If the first and second checksum values do not match an error signal is generated and the hearing aid remains muted.   If the checksum values do match,  an unlock signal is sent to the hearing aid, causing the  hearing aid to resume normal operation
