Patent CA-2057361-C (CA)
Title: Recovery system for submerged instrument
Inventor: CHIN-YEE MARK
IPC: B63C7/22
Filed: 1991-12-10
Granted: 1997-10-21
Abstract: A recovery system for a submerged instrument that includes a buoyant member and an electrically promoted magnetic flux diversion device comprising a pair of pole pieces, a permanent magnet disposed substantially centrally between said pole pieces, and a release plate comprising ferromagnetic material bridging one end of said pole pieces, the pole pieces and permanent magnet forming two flux paths with the metal release plate forming a portion of one of said flux paths. A control winding associated with the pole pieces are disposed for producing a momentary magnetic field opposite to that of the permanent magnet to divert the flux path from the path that includes the release plate to the other flux path. A remotely activated electrical pulse to the control winding diverts the flux path and releases the release plate from the pole pieces allowing the marker buoy to rise to the surface for recovery of instrument or device to which the buoy is attached.

Title: Method for producing by continuous heat treatments oil-tempered steel wires for springs having high strength and high toughness
Inventor: SUGITA HEIJI
IPC: C21D9/02
Filed: 1992-04-09
Granted: 1999-01-19
Abstract: Disclosed herein is a method for continuously hardening and tempering oil-tempered steel wires for springs having high strength and high toughness, and which meet a requirement for weight reduction.  The method is applicable to medium-carbon low-alloy spring steel having a chemical composition which does not undergo martensitic transformation substantially upon oil hardening alone and thus has an Mf point lower than 80° C.  The steel is one which contains carbon in amount of 0.40-0.65 weight %, Si, Mn, and at least one species selected from the group consisting of Cr, Ni, Mo and V.  The method comprises performing a two-step accelerated hardening consisting of subjecting the heated spring steel to oil hardening, wiping oil from the steel, followed immediately by water hardening to produce a hardened steel.  Subsequently, tempering is performed on the hardened steel to produce a tempered steel.

Title: An apparatus and method for varying a signal in a transmitter of a transceiver
Inventor: CAHILL STEPHEN VINVENT
IPC: H04B7/00
Filed: 1991-09-26
Granted: 1996-12-17
Abstract: An apparatus and method for linearizing the gain of a nonlinear power amplifier (115) in a IDM digital transceiver. The power amplifier's transfer function describes a relationship between its input signal and output signal. The output signal is selectively demodulated, substantially with existing receiver elements, during the transmit time slot of a TDM time frame. An inverse transfer function is determined from the nominal gain of the power amplifier (115) and the transfer function. A collection value, corresponding to the transfer function and its inverse, is determined in a vector table. The correction value is multiplied with the input signal resulting in an adjusted input signal. The amplified adjusted input signal produces a varied output signal that is linear to relative to the input signal.

Abstract: A novel dual mode, downdraft gas range provides a sealed top and sealed gas burners that can be operated effectively in a power burner mode with a downdraft exhaust and otherwise in an atmospheric mode.  In the range, a separate and independently operating air/gas supply chamber for each sealed burner is supplied with a controllable flow of gas, and, in the power burner mode, with a controlled forced flow of primary combustion air from a combustion air blower and pressure-adjustable air plenum that supply all air/gas chambers, and each air/gas supply chamber is provided with a gated opening, which is operated to provide an unobstructed flow of primary combustion air from atmosphere in non-power burner operation.  The mixture of air and primary combustion air flows from the air/gas supply chamber through a sealed conduit formed to be free of obstructions and abrupt changes in direction with a flow diffuser provided adjacent the gas burner.  In the power burner mode, the air/gas mixture is combusted without being affected by the downdraft exhaust.
