Title: Heat treatment process and apparatus for metal parts cementation, carbonitriding or heating before hardening
Inventor: COMBIER ALAIN
IPC: C21D1/74
Filed: 1989-12-18
Granted: 1994-12-13
Abstract: The invention is exclusively concerned with heat treatments before hardening, of metallic pieces, by cementation, carbonitridation and heating. The process concerns the feeding of a non muffle heat treatment furnace with various components including nitrogen which is produced by an adsorption or selective permeation generator and which has a residual oxygen content of the order of 2%. According to the invention, after the furnace has ceased to be in operation for a substantial period of time, it is reconditioned by injecting purer nitrogen which has a residual oxygen content lower than 0.3% and which is produced by said generator, adjusted at a lower extraction rate.

Title: Field-based movement sensor
Inventor: WOOD JOHN E
IPC: G01B7/00
Filed: 1990-03-26
Granted: 1997-08-19
Abstract: A field-based movement sensor adapted for measuring strain along a certain axis in an object on which the sensor is attached.  The sensor includes a substrate having a working surface and formed with a pair of fingers projecting from a first direction, and a third finger projecting from a direction opposite the first direction, to a position between the pair of fingers. The pair of fingers and third finger extend generally perpendicular to the axis along which strain is to be measured, with the pair of fingers being moveable with respect to the third finger along the axis when the strain occurs.  An electrically charged element for producing an electric field is disposed on the working surface of the third finger, and a pair of field-effect transistors (FETS) are each disposed on a working surface of a different one of the pair of fingers.  As the object is subjected to strain causing the pair of fingers to move relative to the third finger, the variations in the strength of the electric field from the charged elements to the FETS is determined and this provides a measure of the variation in distance between the third finger and the pair of fingers and this, in turn, provides a measure of the strain in the object to which the substrate is attached.

Title: Vehicle suspension safety system
Inventor: COREY JEFFREY S
IPC: B60G17/015
Filed: 1991-07-24
Granted: 2003-12-02
Abstract: Apparatus and process for shifting vehicle loads between the axles of multi-axle vehicles. The apparatus includes means for automatically restoring pneumatic pressure to the suspension system of an axle when the speed of the vehicle exceeds a predetermined speed. The apparatus also includes means for automatically exhausting the pneumatic pressure if the speed of the vehicle falls below the predetermined speed within a predetermined time from actuating the device. The process includes the steps of automatically restoring pressure to the pneumatic suspension system of a dead axle when a predetermined speed has been exceeded, and again exhausting the pressure if a fall in vehicle speed below the predetermined speed occurs within a specified time. An override in both the apparatus and method prevents exhaustion of the pneumatic pressure after a predetermined time from first exhausting the pressure.

Title: Output level control circuit for use in rf transmitter
Inventor: MIYAZAKI SHINICHI
IPC: H04B1/04
Filed: 1992-07-17
Granted: 1997-04-15
Abstract: An output level control circuit for radio-frequency transmitter which intermittently transmits radio-frequency carrier waves such as seen in the TDMA radio communication system and the digital cellular mobile telephone system.          The variable gain amplifier unit of this transmitter amplifies the transmitting signal to a predetermined output power level in response to a control signal, the output power level is detected by a detecting diode which receives the application of a temperature-compensated bias voltage, and the sum of the detected output and the bias voltage becomes the detection output to the control loop.  The bias voltage of the detecting diode is stored by bias voltage detection means during the off-period of the transmitting signal, an input reference voltage that is supplied in synchronism with the turning-on of the transmitting signal and the stored bias voltage are added by reference signal addition means, and the added output is served as the reference voltage that corresponds to the predetermined output power level.  Power control means generates the control signal in response to the added output and the detection output, and the control signal controls the output power level of the variable gain amplifier unit.

Title: Directly connected display of process control system in an open systems windows environment
Inventor: KILGORE WILLIAM B
IPC: G06F3/048
Filed: 1993-06-02
Granted: 2001-08-21
Abstract: In a display for a process control system, the display can be generated by one of two different sources, but is controlled by only one of them.  A process control system network provides a first source of display, while a windowing system provides a second source.  The control system network provides crucial information to the display regarding the operation of the process control system.  Alternatively, the windowing system allows displays to be generated from a variety of sources including external computer systems. The windowing system controls the display by opening and maintaining windows.  One specific window to be opened is a window in which the control system network can display information.  To allow the control system network to communicate information, a window is opened by the windowing system, and then the process control network is allowed to overwrite information into this newly opened window.          Also, should the windowing system fail, control of the display is given to the control system network.
Patent CA-2099710-C (CA)
Inventor: GRAY LEWIS
IPC: F02C7/00
Filed: 1993-06-29
Granted: 2005-01-04
Abstract: An exhaust system for an axial flow turbomachine is provided having a diffuser that directs the flow of working fluid from a turbine exit to an exhaust housing having a bottom opening, thereby turning the flow 90° from the axial to radial direction. In the exhaust housing, the flow exiting at the top of the diffuser turns 180° from the vertically upward direction to the downward direction. The strength of the vortex formed in the exhaust housing as a result of this turning is minimized by orienting the outlet of an outer exhaust flow guide portion of the diffuser so that it lies in a plane that makes an angle with a plane perpendicular to the turbine axis. As a result, the minimum axial length of the outer flow guide occurs at a location remote from the exhaust housing outlet and the maximum axial length occurs at a location proximate the opening, thereby crowding the vortex against a radially extending baffle in the exhaust housing.
