Patent NO-174406-C (NO)
Inventor: CHANDRAN SRIKUMAR R
IPC: G06F11/16
Filed: 1986-05-09
Abstract: The present invention is an input/output controller for providing total data integrity for any single point failure. The I/O controller comprises a processor module having two microprocessors, an associated memory, a direct memory access module (<<DMA>>), and a processor support module (<<PSM>>); a device drive interface; and a channel interface. The two microprocessors are operated in lockstep as a dual modular redundant processor system. The processors provide true and complement, respectively, addresses, data and control strobes. The PSM compares the true and complement data to detect errors (i.e., corresponding data bits not being a true-complement pair) and generates parity protected data (and checks parity) on the data bus. The PSM also generates and checks dual railed control strobes and provides synchronization of all control strobes and interrupt signals to enable the true-complement pair of microprocessors to operate in lock-step. The DMA compares the redundant addresses from the processors to detect errors and to generate parity protected addresses (and check parity) on the address bus. The DMA also generates and checks bus arbitration signals and controls direct memory access. Self-checking checkers are used to check the various dual railed, true-complement pairs of signals to detect, locate and isolate faults. Miscompares between true-complement address, data and control signals and parity errors detected in reading program instructions from memory all are treated as fatal errors, which cause both processors to halt. Other types of errors are treated as nonfatal, which cause processor exceptions during which appropriate programming is executed to locate and isolate such errors.

Abstract: A transformer system for measuring electrical current includes an electrical conductor having first and second conductor portions. The first conductor portion conducts electrical current in one direction and the second conductor portion conducts the electrical current in an opposite direction. The first conductor portion produces a magnetic field Ha and the second conductor portion produces a magnetic field Hb. A coil having a non-ferromagnetic core is positioned between the first and second conductor portions so that the axis of the coil is substantially parallel to the magnetic fields Ha and Hb. The separation between the outer circumferential surface of the coil and the first and second conductor portions is the minimum distance for avoiding a voltage breakdown therebetween for a predetermined maximum electrical current in the conductor portions. At least one ferromagnetic shield surrounds the first and second conductor portions for shielding the coil from external magnetic fields.

Title: Induced draft, fuel-fired furnace apparatus having an improved, high efficiency heat exchanger
Inventor: SHELLENBERGER TIMOTHY J
IPC: F24H3/08
Filed: 1989-11-24
Granted: 1995-01-03
Abstract: RHEE     ABSTRACT         An induced draft, fuel-fired upflow furnace is provided with a compact,  high efficiency heat exchanger having horizon-tally spaced apart inlet and outlet manifold structures which are innerconnected by a horizontally spaced series of vertically ser-pentined, relatively small diameter flow transfer tubes.  Larger diameter inlet flow tubes are positioned beneath the balance of the heat exchanger, extend parallel to the transfer tubes, and have upturned discharge ends connected to the underside of the inlet manifold.   The heat exchanger is configured so that its total vertically facing peripheral surface area is considerably Larger  than  its total  horizontally  facing  peripheral  surface area,  thereby  significantly  reducing  undesirable  outward heat loss through the vertically extending furnace housing side walls upon burner shut off and increasing the overall efficiency rating of the furnace.   The small diameter, serpentined transfer tubes create a significant flow restriction within the heat exchanger to thereby increase heat transfer to the continuing supply air flow through the furnace after burner shut off.  The reduced mass of the heat exchanger, compared to conventional clamshell heat exchangers, also desirably lessens its cold startup "dwell time" to inhibit internal heat exchanger corrosion.   A pilot bypass system is provided to inhibit internal heat exchanger corrosion potentially caused by the continuously generated combustion pro-ducts of a standing pilot flame within the furnace housing by venting  such  combustion  products  directly  through the  draft inducer fan outlet section and into the exhaust flue,  thereby bypassing the heat exchanger, during idle periods of the furnace.

Title: Method and apparatus for determining load holding torque
Inventor: WYCOFF DAVID C
IPC: B66B1/28
Filed: 1990-01-24
Granted: 1995-10-24
Abstract: A motor control method and apparatus for a hoist is disclosed in which a drive motor is connected to an adjustable frequency power supply in which the frequency of the power supplied to the motor can be selectively varied.  At the initiation of a hoist operation, when the hoist brake is holding the motor and an object constituting a load on the motor stationary, power is supplied to the motor at a predetermined low frequency which is sufficient to provide load holding torque upon release of the brake.  The actual current level of the power supplied to the motor is sensed at the initiation of the hoist operation and a signal representative of that current level is compared with a reference signal representative of a current level which is sufficient to provide the load holding torque.  If the signal representative of the actual current level of the power supplied to the motor exceeds the reference signal, an output signal is provided which will result in the release of the hoist brake from its holding condition.

Granted: 1995-10-24
Abstract: A method and apparatus for controlling field current in an alternator maintains the alternator output voltage at a defined level and substantially suppresses transients in the event the alternator is disconnected from a load.  A pair of MOS Insulated Gate Bipolar Transistors (MOSIGBT's) are connected one in series and one in parallel with the alternator field winding and current is provided to the field winding through the series connected regulator transistor as needed to maintain the alternator output voltage.  The field current is auto-commutated through the parallel connected transient suppression transistor when the regulator transistor is off.  When the alternator is disconnected from a load, both transistors are switched off in a controlled manner to discharge the field winding energy at a high voltage and at an accelerated rate within the parallel connected transistor.  The series connected transistor is nearly instantaneously turned off to remove the source of field current and the parallel connected transistor is "ramped" off or turned off at a controlled rate to act as a controlled resistance and thereby dissipate the field energy at a high voltage level.  By dissipating the field energy at a high voltage level, the dissipation time is substantially reduced as compared to prior art arrangements.  The present invention is generally applicable to alternator circuits and is particularly applicable to automotive battery charging systems.

Title: Facsimile communication apparatus
Inventor: SHIMONAGA SADAAKI
IPC: H04N1/32
Filed: 1990-08-16
Granted: 1994-11-01
Abstract: In the existing facsimile apparatuses with telephone function, those having the function of storing the received acoustic signal when the subscriber is absent are known.          Hitherto, modulation/demodulation and memory of image data and acoustic data have been executed in independent com-positions, and the structure was large and complicated.          Besides, various pieces of voice information sent out upon arrival of acoustic signals were also processed in independent compositions, and versatile use was difficult.          In the invention, the acoustic data is processed by using image data processing apparatus, and acoustic data is stored in image memory.  Moreover, when storing image data and acoustic data in image memory, each memory region is set dynamically.  Further, the voice data sent out upon arrival is stored in part of the program memory controlled by the CPU.  As a result, the structure is reduced in size and simplified, and complicated combined processing of voice signal being sent out may be realized.
