Patent CA-2029333-A1 (CA)
Title: Flow meter for measuring the flow rate in a conduit
Inventor: HAUSSLER HUBERT
IPC: G01F1/22
Filed: 1990-11-05
Abstract: The flowmeter includes a piston that is biased by a spring to a neutral position within an encircling collar, and the piston is movable relative to the collar by and in the direction of the fluid flow to be measured.  Movement of the piston relative to the collar increases the fluid flow through one or more slots provided in one of such components.  A Hall device senses movement of a magnet connected to the piston, and produces an output signal.  A linear relationship between the output signal and the rate of flow of the fluid can be achieved by utilization of a magnetic member whose magnetic intensity or cross-sectional shape varies along its length, or by causing the magnet to move along a curve or other path of travel that varies its distance from the probe of the Hall device.

Title: Impact sensor
Inventor: SUZUKI OTOHIKO
IPC: G01P15/00

Abstract: ABSTRACT     The present invention provides an impact sensor which has neither electrical contacts exposed to an atmosphere nor any movable components, which is durable and highly reliable, and which is able to safely sense a vehicle impact even if loaded in a vehicle for a considerable period of time.  The impact sensor comprises a piezoelectric element (3, 13) for generating a voltage of a magnitude in accordance with a pressure, a pair of electrodes (lc, ld, llc, 14) disposed to sandwich the piezoelectric element, an inertial mass (6, 16) adapted to apply a pressure to either one of the electrodes, and a biasing member (7, 17) for biasing the inertial mass (6, 16) toward the piezoelectric element (3, 13).          When the inertial mass (6, 16) is subject to an impact, the inertial mass (6, 16) is biased to apply to the piezoelectric element (3, 13) a pressure of a level in accordance with the magnitude of the impact.  The piezoelectric element (3, 13) then provides a voltage of a magnitude in accordance with the pressure applied thereto.

Abstract: The mobile station to base station access in a cellular radio system is a classical problem of random multiple access using a shared common channel. Many multiple access protocols have been invented in the past with varied degrees of success in improving the throughput of the multiple access channel. The current invention is a new multiple access protocol which enhances the throughput and reduces the access delay by providing feedback of the detailed status of the access channel from the base station to the mobile station. The feedback mechanism and multiple access protocol are also applicable to other types of radio or wire-based channels.

Patent CA-2058789-A1 (CA)
Inventor: HOUSER DANIEL M
IPC: E21B7/04
Filed: 1992-01-06
Abstract: This invention pertains to a method of installing well conductors  in such a way that the load upon the platform is significantly  reduced thereby also eliminating the need for additional framing members.  In accordance with this method, an end region of a well conductor  is plugged which, if the conductor has a  diameter-to-wall  thickness  ratio of about thirty to one (30:1),  will   cause  the  conductor  to achieve nearly neutral buoyancy.  By selectively   adjusting   the    buoyancy of the conductor,  such as   by   flooding or de-ballasting, additional conductor  lengths may be  added  without imposing an unduly large load upon the platform.  In this fashion, a smaller crane will be able to lower the conductor string without the need for a much larger derrick crane, which may then be more efficiently used solely to upend and stab the elongated conductors through the platform.

Title: Isolator switch for metal-clad, compressed-gas-insulated high-voltage switch-gear
Inventor: LORENZ DIETER
IPC: H01H31/32
Filed: 1990-09-19
Abstract: Abstract of the Disclosure 1. ISOLATING SWITCH FOR METAL-CLAD, COMPRESSED-GAS INSULATED HIGH-VOLTAGE SWITCHGEAR   21. Due to the relatively slow actuation of the main contact pin (3) of an isolating switch (1), it is customary to provide a spring loaded auxiliary contact pin (7) situated inside the main contact pin (3). In the same way as the main contact pin (3), this auxiliary contact pin (7) comes to abut against amating contact (28) and remains there at the beginning of the opening movement until it is returned to the neutral position with a velocity that is greater than the movement of the main contact pin (3) by the spring (8) after being released by a mechanical control unit (14).   22. The mechanical control unit (14) contains a rotatably supported lever arrangement (15), which locks automatically in the neutral position and retains the auxiliary contact pin (7) until it is released by a guide surface (21) connected to the main contact pin. The mating contact (28) of the auxiliary contact pin (7) is also spring-loaded and follows this auxiliary contact pin (7) somewhat after being released, initially while maintaining the equipotential bonding.   23. The isolating switch is advantageous for metal-clad, compressed-gas insulated high-voltage switchgear, whose function is to switch the magnetizing currents in transformers.

Title: Means for terminating a tristatable electrical bus

Filed: 1992-05-29
Abstract: ABSTRACT       AN IMPROVED MEANS FOR TERMINATING A TRISTATABLE                  ELECTRICAL BUS The present invention provides a bus system terminator to ensure that during a tristate condition of a bus system, the bus system is placed into a known state.  The bus system terminator should not unduly load the bus system when the bus system is in a non-tristated condition.  There is also an enable signal that is present when the bus system is in the tristate condition. The bus system terminator is made up of a plurality of current limiting resistors connected to the bus system, one resistor for each signal in the bus system.  A switch or buffer connects the current limiting resistors and a logic generator.  The logic generator can be a logic state or the output of a gate.  The switch receives the enable signal and in the presence of the enable signal, the switch connects the current limiting resistors to the logic generator, thereby allowing the logic generator, through the current limiting resistors, to place the known logic state onto the bus system.
