Title: Motorless batch carbonator
Inventor: RUDICK ARTHUR G
IPC: A23L2/00
Filed: 1990-06-05
Abstract: A motorless batch carbonator for a carbonated drink dispenser is located in a chilled water bath (18) including a set of evaporator coils (16) located on the outside of the water bath with the ice build up on the inside thereof being controlled by an ice bank detector (22). The carbonator is comprised of an immersible closed tank (30) including a semi-permeable membrane carbonating section (32) where still water and CO2 gas are mixed together. Still water from a pressurized source is fed into the interior of the carbonator tank which is pressurized to operate a spring-biased spool valve (42) for opening and closing a CO2 supply line (50).  A vent passage (70) through the top of the carbonator chamber is opened and closed to atmospheric pressure in response to the manual actuation of a spring-biased dispensing plunger (64) which includes a fluid dispensing path (62). A constrained spherical float device (80) resides on the surface of the carbonated water inside of the tank and to open and close the vent passage and thus control tank pressurization and operation of the spool valve controlling the supply of CO2.

Title: Method and circuit for testing transmission paths
Inventor: GAUTHIER JOHN A
IPC: H04B17/309
Filed: 1991-12-11
Abstract: A circuit for testing the integrity of transmission paths includes a first linear feedback shift register (LFSR) adapted to generate a periodic sequence of pseudo random test data for transmission on the transmission paths.  A second LFSR synchronizes to the transmitted test data after being provided with a seed value corresponding to a transmitted data word.  After synchronization, the second LFSR is set to a free running mode and independently generates a pseudo random sequence of patterns corresponding to the sequence generated by the first LFSR.  A comparator compares the pseudo random data generated by the second LFSR with the pseudo random data received from the transmission paths.  If a mismatch occurs a signal indicating an error condition is asserted.

Inventor: ICHIHARA MASAKI
IPC: H03M1/44
Filed: 1992-06-17
Abstract: In an analog-to-digital converter, one-bit A/D conversion stages are connected in series to receive an analog signal. Each conversion stage includes a sample-and-hold circuit for sampling an analog signal from a preceding stage, a comparator for comparing it with a specified voltage level to produce a logic signal at one of two discrete levels depending on whether the signal received from the preceding stage is higher or lower than the specified level. The signal received from the preceding stage is summed with a prescribed reference voltage of one of opposite polarities depending on the level of the logic signal to produce an analog output signal. The successive conversion stages are driven so that the analog signal from each stage is transferred to the next, and the logic signals generated by the individual conversion stages are delayed so that they appear simultaneously at digital output terminals.

Patent CA-2078452-A1 (CA)
Inventor: ZULASKI JOHN A
IPC: H02H1/06
Filed: 1992-09-17
Abstract: An arrangement is provided for accurately sensing the source voltage of a high-impedance source while supplying a variable burden. A current-sensing element is connected in series with a load circuit across a high-impedance source. The load circuit includes a variable burden load. A shunt regulator is connected with the variable burden load and is arranged to operate so that the combination of the shunt regulator and the variable burden present a controlled, nearly constant burden to the high-impedance source. The source voltage of the high-impedance source is sensed via the voltage across the series current-sensing element. While the output voltage is directly proportional to the burden, the output current is essentially unaffected by small variations in the burden. Thus, the current through the series current-sensing element is utilized to accurately sense the voltage of the high-impedance alternating-current source while also supplying the variable burden load such as a battery, electrical circuitry, and a switch operator.
