Patent CA-2016596-C (CA)
Title: Air filter with horizontal filter elements
Inventor: WILLIAMS ROGER D
IPC: B01D46/24
Filed: 1990-05-11
Granted: 1997-10-21
Abstract: Apparatus for filtering dust and the like entrained in a flow of transport air which includes an enclosed housing having an upper filtering portion and a lower hopper  for collecting dust.   A plurality of  filter elements are disposed in the upper housing portion, and a specially formed inlet plenum directs the transport air with  entrained  foreign particles  in  a  predetermined direction toward the hopper so that heavier particles of dust are carried directly to the hopper by inertia rather than collecting on the filter elements.   The filter elements are supported solely by a cluster of support rods extending across the housing, and an access opening and closure door are provided for inserting and removing the filter elements.  A latch assembly is provided which slidably  engages  the  enclosure  door  at  its  closed position, after which it can be tightened, all without requiring any special tools.

Inventor: EDWARDS DOUGLAS F
IPC: F16H3/083
Filed: 1990-07-18
Granted: 2000-11-21
Abstract: A transaxle or gear drive unit with ar improved shift mechanism and gear drive is set forth. The shift mechanism is of the shift key type and certain gears have recesses to receive a lug of the shift key with the recesses having ramps which depress the lug when the key is shifted. One of the gears has a smooth bore adjacent the recesses to serve as a neutral position for the shift key. A wide gear having teeth or splines around its periphery extending the length thereof is rotatably mounted on one shaft of the gear drive unit. The wide gear has a plurality of additional gears affixed thereto fox simultaneous rotation. The wide gear extends beyond the additional gears and connects with a forward speed gear and a reverse gear on another shaft. The wide gear thus functions as a mechanical connection for the additional gears as well as serving as a gear itself.

Title: Semiconductor strain sensor and manufacturing method thereof
Inventor: KONDO MUNENARI
IPC: G01P15/08
Filed: 1990-08-30
Granted: 1998-09-01
Abstract: A semiconductor strain sensor comprising a substrate having a lead hole in which a lead terminal is installed so as to be electrically coupled to an external circuit and a sensor chip joined with the substrate and having piezo-resistors to a bridge circuit.  A shell is joined with the front surface of the substrate by means of a projection welding technique after the back surface of the substrate is flattened, said sensor chip being covered by the shell and a space formed by the shell and the substrate being filled with a damping liquid.  The substrate is integrally coupled to the sensor chip through an adhesive, and spacers are added to the adhesive so as to keep the thickness of the adhesive to a predetermined value.  This arrangement can effectively prevent the propagation of the welding strain of the substrate into the sensor chip.

Title: Sulfur treatment of magnesium-contaminated fe-cr-al alloy for improved whisker growth
Inventor: SIGLER DAVID R
IPC: C23C8/10
Filed: 1990-11-29
Granted: 1995-11-28
Abstract: A method for producing aluminum-containing ferritic stainless steel from a magnesium-contaminated melt such that the steel is suitable for growing oxide whiskers to cover the surface thereof is disclosed.  The method comprises adding sulfur to the contaminated melt in an amount sufficient to increase the sulfur content not less than 1.3 times the magnesium content, whereupon the sulfur reacts with the magnesium to render the magnesium inert to whisker growth.  The method also preferably comprises an addition of titanium, zirconium or hafnium in amounts sufficient to react with residual sulfur in excess of the amount required for magnesium reaction, thereby mitigating the adverse affect of sulfur on oxide adhesion.
Patent CA-2032414-C (CA)
Title: Method and apparatus for decoding two frequency (f/2f) data signals
Inventor: HARRISON CLARENCE
IPC: G11B20/14
Filed: 1990-12-17
Granted: 1995-09-12
Abstract: A two-frequency data signal is accurately decoded by sampling the  signal  and digitizing the  samples to provide  a series of digital values representing the signal. An intelligent digital  filter manipulates  the  digital  values  to  decode  the signal, by detecting the peaks in the sampled signal and decoding the signal by analyzing the location and amplitudes of the peaks. Only peaks which are outside a guard band may be detected. If the signal cannot be properly decoded with a wide guard band,  the guard band may be repeatedly narrowed, until a minimum guard band is reached. Bits are identified by comparing the displacements between  peaks  to  a  bit  cell  width.  An  even  number  of displacements  indicates  a  '0'  bit,  and  an  odd  number  of displacements indicates a '1' bit. Once a bit is decoded, the bit cell width is incremented by a predetermined amount if the bit cell width is wider than the current bit cell width,  and is decremented by a predetermined amount if the decoded bit cell width is narrower than the current bit cell width.  If no peaks are found within a maximum allowable bit cell width, this area is delimited as bad.

Title: Multiple cluster signal processor
Inventor: TOWER LEE W
IPC: G06F15/173
Filed: 1991-02-20
Granted: 1995-01-03
Abstract: A signal processor architecture that comprises a data network having multiple ports, a control bus, and a plurality of signal processing clusters connected to at least two ports and the control bus. Each signal processing cluster comprises a systemcontrol processor connected to the control bus, a second control bus, and a global bulk memory having multiple ports. A plurality of functional processing elementsare connected to the system control processor by way of the second control bus, and each are connected to a port of the global bulk memory. The global bulk memory comprises a subdata flow network having multiple gateways and full crossbar inter-connectivity between each of the multiple gateways. The data network and subdataflow network allow data to be transferred between functional processing elements in the signal processing cluster and any functional processing element and global bulk memory in another signal processing cluster, and allow data to be transferred from any functional processing element into and out of the processor architecture. The first control bus is arbitrated for access on a message by message basis and the data network is arbitrated on a message by message basis for transfers between ports.This results in a relatively loose coupling between the signal processing clusters. The second control bus is arbitrated for access on a word by word basis and the global bulk memory is arbitrated for port access on each global bulk memory cycle. Thisresults in tight coupling within each signal processing cluster.

Title: Two-stage valve
Inventor: GAWLICK DIETER
IPC: B60T11/224
Filed: 1992-09-25
Granted: 1995-06-20
Abstract: A two-stage brake control valve has a larger first stage and a smaller second stage.  First stage operates to fill a brake.  Then, after a transition phase only the second stage is used to supply the working pressure.  A check valve is between the first stage pressure chamber a sump.  The check valve opens if the pressure in the first stage pressure chamber exceeds a predetermined value.  To minimize the operating force of the valve and to avoid a sudden change of the valve working pressure during the changing phase, the closing force of the check valve is controlled as a function of the valve working pressure.  The valve working pressure acts on a valve spool which influences the closing force of the check valve in the way that the closing force decreases with increasing working pressure.

Inventor: MCNAIR BRUCE EDWIN
IPC: G06F1/28
Filed: 1993-03-31
Granted: 1999-03-23
Abstract: The frequency of a timing signal generated by a timing source apparatus for battery-operated, clock-driven electronic devices is reduced in a predetermined manner as the battery voltage decreases. The timing source is electrically connected to the internal clock of the device to dictate the speed of that clock. As the frequency of the timing source is decreased in response to lower battery voltage, the internal clock speed of the device is proportionately reduced, causing reduced power consumption and prolongation of the life or charge cycle of the battery.
