Title: Dual-coded data comparator
Inventor: WIEGAND HERMANN-JOSEF
IPC: G06F1/035
Filed: 1991-10-28
Abstract: ABSTRACT OF THE DISCLOSURE   A fast, flexible hardware comparator is implemented using read-write memory chips (RAMs). Characteristic data is stored at a specific address corresponding to the reference value, which can be read out only in case of agreement when addressed by the actual value. To reduce the addresses to be decoded in the RAMs, the required address lines are evenly distributed among several RAMs. The present invention can be used as an address comparator in software testing, and as a reference/actual value comparator in digital control circuits, if the address difference from the reference value address in each case is additionally stored in the RAMs.

Inventor: BADDOUR RAOUF E
IPC: A01M29/30
Filed: 1992-03-02
Abstract: ABSTRACT             Electric-Bubbler Deterrent for Zebra Mussel and Ice by Raouf E. Baddour and Walter J. Lenson This invention is concerned with a method of preventing zebra mussels and ice from blocking water intakes. The similarity of the entrainment process responsible for zebra mussel infestation and anchor ice formation at water intakes is recognized. Accordingly, a preventive method is adopted to control zebra mussels at the larval stage and ice at the frazil stage. Electrofishing and bubbler technologies are synthesized in a novel deterrent to prevent the blockage of a water intake throughout the year. An optional thermal component is added to the deterrent to control ice in extreme cold weather conditions. The deterrent can be installed directly on existing water intakes. To minimize energy cost the deterrent may be operated only during periods of zebra mussel infestation and/or ice formation. The power to operate the deterrent may be obtained from conventional or non-conventional sources of electricity ( e.g. wind turbine).

Title: High density single pass heat exchanger for drying fragmented moisture-bearing products
Inventor: RONNING RICHARD L
IPC: F26B19/00
Filed: 1992-06-25
Abstract: A high density, single pass heat exchanger (26) is provided which is designed for drying products such as bakery wastes, alfalfa, peat moss, wood or similar fibrous products. The exchanger (26) has a series of circumferentially spaced, inwardly directed heat transfer sheet metal flights (48) presenting a central flight-free zone (74), together with a series of baffles (282-288) in axially spaced relationship along the length of the exchanger (26). A number of annular deflectors (294-298) are mounted within the exchanger (26) between adjacent baffles (282-288), such that the baffles (282-288) and associated deflectors (294-298) cooperate to cause the material being dried to follow an essentially serpentine, generally helical path (300). The exchanger (26) is capable of efficiently removing moisture from wet products by virtue of the fact that the diameter (R) of the exchanger (26) to the diameter (r) of the internal flight-free central zone (74) is from about 1.4-2.4. The disclosed exchanger design may be used for updating existing three-pass and single-pass dryers, or for the fabrication of new systems.

Title: Thermal response switch and a surge absorbing circuit using the same
Inventor: IKEDA FUJIO
IPC: H01H37/52
Filed: 1992-06-25
Abstract: A surge-absorbing element is parallel-connected to an electronic device via a pair of communication lines. A normally-closed thermal-response switch is serially-connected between the electronic device and the signal sourceon the input side of the surge-absorbing element. When a surge voltage is instantaneously applied to the communication lines, the thermal-response switch remains in the closed position and the surge-absorbing element acts to suppress the surge voltage. When an overvoltage or overcurrent is continuously applied to the communication lines, thermal-response pieces of the thermal-response switch open to release the movable body. The electronic device is thereby disconnected from the signal source, thus stopping the overvoltage or overcurrent from continuing to flow to the electronic device and the surge-absorbing element. Simultaneously, a reset pin is projected through the casing. After the temperature of the switch decreases, the switch is reset to the closed position by pushing the reset pin, which reconnects the electronicdevice to the communication lines.

Title: Air compression system
Inventor: STADLER DAVID M
IPC: F04D29/58
Filed: 1992-07-10
Abstract: ABSTRACT OF THE DISCLOSURE                The disclosure relates to a fully integrated single stage centrifugal air compression system exhibits a relatively high flow rate at relatively low pressure.  The air compression system comprises a single impeller that is driven through a belt drive by a conventional electric motor.  A novel parallel wall axially split diffuser converts the high kiniteo energy of air leaving the impeller into pressure energy.              Cooling of the air compressor is achieved by an integral fan on the motor pulley which draws filtered ambient air into a plenum.  Plenum air is ducted through a novel system of heat exchangers which draw heat from the compressor bearings.  A passage through the center of the compressor drive shaft conducts pressurized air from the plenum through the drive shaft to cool the bearings, resulting in a bearing running temperature slightly above ambient.

Title: Carrier frequency error detector capable of accurately detecting a carrier frequency error
Inventor: IWASAKI MOTOYA
IPC: H04L27/233
Filed: 1992-07-29
Abstract: On detecting a carrier frequency error in a received signal, a correlation unit (12) detects a correlated signal in signals which a transmission unique word signal in the received signal and a local unique word signal are differentially detected.  A frequency fine detection unit (17) detects a fine frequency error by using the correlated signal and a frame timing signal.  A frequency coarse detection unit (21) detects a coarse frequency error by using the buffered signal from a data buffer (20) and the frame timing signal.  A first adder (25) adds the fine frequency error to the coarse frequency error to a first added signal.  A second adder (31) adds the first added signal to a maximum power frequency detected by a maximum power frequency detection unit (27) to produce the carrier frequency error.

Abstract: ABSTRACT   A method of sun search and acquisition is disclosed for a spacecraft (18) which is stabilized in three axes. The method utilizes three axes gyro rate and integrated rate sensing together with three simple slit type sensors (10, 20, 30, 40). The method starts from an arbitrary attitude and from body rates up to the limits of the gyro rate sensors and is comprises of a rate nulling step followed by two consecutive simple search procedures. One search procedure is about the pitch axis until alignment of the sun with the roll/pitch plane and the other search procedure is about the yaw axis until alignment of the sun with the roll axis. The sun acquisition culminates in pointing the roll axis of the spacecraft (18) toward the sun. By using slit typesun sensors (10, 20, 30, 40) versus a wide field of view sensor it is easier to find a mounting location on a spacecraft (18) which is free from spurious reflections off other parts of the spacecraft.
