IPC: F16B4/00
Filed: 1990-04-05
Granted: 1997-11-11
Abstract: A refractory assembly includes a refractory outer member having therein an opening defined by an inner surface and a refractory inner member having an outer surface.  The dimension of the outer surface of the inner member is greater than the dimension of the inner surface of the outer member by an amount of from 0.05 to 0.15 mm.  The outer member is heated to at least 1000°C to thereby increase the dimension of the inner surface.          The inner member then is inserted into the opening in the outer member, and the outer member then is cooled to room temperature.          As a result, the inner surface of the outer member shrinks against the outer surface of the inner member to thereby form an interference shrink fit joint between the members.

Title: Regenerative rf bidirectional amplifier system
Inventor: SOHNER HAROLD K
IPC: H04B5/00
Filed: 1991-01-08
Granted: 1995-04-11
Abstract: A regenerative RF bi-directional communications system is provided for establishing RF coverage within a RF block tunnel area.  The system uses a plurality of cascaded amplifier stages for periodically regenerating signals which are transmitted and received along a series of radiating cable length which link base station transceivers to hand-held or like mobile communication units. An intermediate frequency distribution system is used so that the required level of amplification is achieved through the several cascaded amplifier stages at the level of low-power IF signals generated from the original RF signals in conjunction with the appropriate oscillator and pilot signals. The IF distribution system restricts the cascading effect occurring due to the plurality of cascaded amplifier stages on the relatively low-power IF signals, thereby producing a negligible amount of intermodulation.

Inventor: HERMAN FRED WADE
IPC: G01V3/00
Filed: 1991-07-22
Granted: 1999-07-06
Abstract: A batteryless, portable, frequency divider includes a first resonant LC circuit that is resonant at a first frequency for receiving electromagnetic radiation at the first frequency; and a second resonant LC circuit that is resonant at a second frequency that is one-half the first frequency for transmitting electromagnetic radiation at the second frequency.  The first circuit is coupled only magnetically to the second circuit to transfer energy to the second circuit in response to receipt by the first circuit of electromagnetic radiation at the first frequency.  At least one of the resonant circuits includes a variable reactance element, such as a variable capacitance diode or varactor.  In a variable reactance element of the first circuit, the reactance varies with variations in energy received by the first circuit for causing the second circuit to vary in reactance due to mutual reactive coupling to cause the second circuit to transmit electromagnetic radiation at the second frequency in response to the energy transferred from the first circuit at the first frequency.  In a variable reactance element of the second circuit, the reactance varies with variations in energy transferred from the first circuit for causing the second circuit to transmit electromagnetic radiation at the second frequency in response to the energy transferred from the first circuit at the first frequency.  Both resonant circuits include inductance coils that are disposed on a ferrite rod, for enhancing the magnetic coupling.  The frequency divider is included in a tag utilized in a presence detection system.
Patent CA-2058734-C (CA)

IPC: G06F12/08
Filed: 1992-01-03
Granted: 2002-06-25
Abstract: A fault-tolerant storage device array using a copyback cache storage unit for temporary storage. When a Write occurs to the RAID system, the data is immediately written to the first available location in the copyback cache storage unit. Upon completion of the Write to the copyback cache storage unit, the host CPU is immediately informed that the Write was successful. Thereafter, further storage unit accesses by the CPU can continue without waiting for an error-correction block update for the data just written, In a first embodiment of the invention, during idle time for relevant storage units of the storage system, an error-correction block is computed for each "pending" data block on the copy-back cache storage unit, and the data block and corresponding error-correction block are copied to their proper location in the RAID system. The copyback cache storage unit in effect stores "peak load" Write data and then completes the actual Write operations to the RAID system during relatively quiescent periods of I/O accesses by the CPU. In a second embodiment of the invention, after Write data is logged to the copyback cache storage unit, normal Read-Modify-Write operation by the RAID system controller continues in overlapped fashion with other CPU I/O accesses using Write data in the controller's buffer memory.      Performance is enhanced because the CPU can continue processing as soon as the simple Write operation to the copyback cache storage unit completes, thus eliminating the delay caused by a normal Read-Modify-Write RAID system. in this embodiment, the copyback cache storage unit acts more as a running "log" of Write data.

Title: Method and system for automatic modem protocol selection in a cellular communications system
Inventor: BRIGIDA DAVID JOSEPH
IPC: H04W24/00
Filed: 1993-01-07
Granted: 1998-03-31
Abstract: A method and system are disclosed for automatically selecting an optimum modem protocol in a distributed data processing system which includes a modem which supports multiple protocols which is coupled to a cellular communications system. Known cellular communications systems generate a Received Signal Strength Indicator (RSSI) and a Service Access Tone (SAT) which may be utilized by a cellular telephone to determine the amplitude of a received signal and to optimize a path through the cellular communication system for voice communications. The Service Access Tone (SAT) is generally utilized to control the "hand off" of a communication session to a new cell and provides an indication of the quality of the existing path through the cellular communication system.  After initiating communication between a first modem and a second modem, the method and system of the present invention automatically determines the channel quality within the cellular communication system by utilizing the Received Signal Strength Indicator (RSSI) and the Service Access Tone (SAT). These signals are analyzed, in conjunction with the bit error rate of the dotting sequence transmitted by the answering modem, to achieve an indication of the quality of the cellular communications channel. In response to an analysis of these factors a particular protocol may be selected which is optimum for existing channel conditions.
