Patent CA-2098153-A1 (CA)
Inventor: DANISCH LEE A
IPC: G01B11/16
Filed: 1993-06-10
Abstract: A curvature or bending and displacement sensor is composed of a fiber optic or light wave guide, for attachment to a member or members being curved or displaced. Light is injected at one end and detected at the other end. Curvature of the fibre results in light loss through an emission surface or surfaces, sometimes in conjunction with a superimposed curvature in a plane other than that of the curvature to be measured, this loss being detected. The loss of light detection is used to produce indication of curvature or displacement. The light emission surfaces extend in a substantially circumferential direction, or in a substantially curved axial direction when in a curved portion of a curved guide. The placement, shape and configuration of the emission surfaces allows adjustment of the linear range of measurement, the overall throughput of light, and the length over which curvature is measured. Two or more light guides can be oriented to given indication of direction of curvature or displacement.

Abstract: QUICK RELEASE TANK SUPPORT BRACKET WITH POSITIVE LOCKING ENGAGEMENT MEANS                      ABSTRACT OF THE DISCLOSURE The present invention comprises a quick release tank support bracket having a positive locking engagement along with an optional operative seat back supportive assembly which includes support bars mounted with a frame with clamp arms secured to the support bars.  At least two such support bars are included with at least one or more clamp arms secured thereto.  The clamp arms are movable between a closed position for retaining of a tank therein and an opened position for releasing of the tank therefrom.          Each of the support bars includes a crank arm which is interconnected by an inner engagement device for controlling cooperative relative movement of the two clamp arms with respect to one another.  Closure lugs are positioned integral with the clamping arms and extend inwardly and include tank engaging surfaces such that when the tank is inserted into place by pushing horizontally toward the backing plate, the clamping arms and the support rods will automatically move to the tank retaining position.  Also simultaneously the seat back members which are secured to the clamping bars will move together to form a rear seat cushion area for a conventional seat as may be used on emergency vehicles such as fire trucks and the like.

Abstract: A method is disclosed for correcting measurement errors caused by clock deviations in a secondary radar system.      To determine any deviation of the clocks of two ground stations (S1, S2; ... S1, S4) from each other, two interrogation/reply cycles are performed in direct succession in opposite directions over the same transmission path (d1 + d2): - Interrogation by ground station S1, reception of the reply from airborne station BS by ground station S2. - Interrogation by ground station S2, reception of the reply by ground station S1.      The two transmission periods differ by twice the deviation of the clocks in the two ground stations S1, S2.      The measured deviation is used to correct the measured transit time values and/or to synchronize the clocks.      Synchronization of several ground stations with a master station is achieved by successive interrogation/ reply cycles between the master station (S1) and all other stations (S2 - S4).

IPC: C23C16/40
Filed: 1993-09-30
Abstract: ABSTRACT OF THE DISCLOSURE Articles for hot hydrocarbon fluid wherein the surface for contacting the fluid is a metal oxide, amorphous glass or metal fluoride diffusion barrier material coated on a metal substrate.  The metal oxide, amorphous glass or metal fluoride is deposited by chemical vapor deposition (CVD), e.g., by effusive CVD of an organometallic compound on the surface without the use of carrier gas, without pre-oxidation of the surface and without thermal decomposition of the diffusion barrier coating materiel.  Examples of coating materials deposited by effusive CVD are Ta2O5, SiO2, TiO2, spinel and Al2O3. The articles having the coated surfaces find utility in components subjected to high temperatures wherein the components are in contact with hydrocarbon fluids without additives, without special attention to quality control and without the need for special processing.

Title: Initiating a response signal to a predetermined processing condition
Inventor: WEBER MARK J
IPC: G01N25/18
Filed: 1994-02-08
Abstract: Abstract of the Invention The present invention provides a method for initiating a responsive signal to a predetermined processing condition.          The method relies upon generating sufficient processing data about a desired processing condition to establish a processing profile reflective of the condition.  The predetermined processing condition is indexed or inputted onto the profile which, in turn, allows for automatically initiating the signal when subsequent processes achieve the indexed condition.  The method is particularly applicable for determining a proper curding point in a cheese manufacture using a control computer to store and compare an indexed processing profile with an on-going plant run.

Title: Combination parallel/serial execution of sequential algorithm for data compression/decompression
Inventor: HASSNER MARTIN A
IPC: H04B1/66
Filed: 1994-04-26
Abstract: COMBINATION PARALLEL/SERIAL EXECUTION OF SEQUENTIAL ALGORITHM FOR                  DATA COMPRESSION/DECOMPRESSION                             Abstract An apparatus and method for executing a sequential data compression algorithm that is especially suitable for use where data compression is required in a device (as distinguished from host)  controller.   A history buffer compresses an array of i identical horizontal slice units. Each slice unit stores j symbols to define j separate blocks in which the symbols in each slice unit are separated by exactly i symbols.   Symbols in a string of i incoming symbols are compared by i comparators in parallel with symbols previously stored in the slice units to identify matching sequences of symbols.  A control unit controls execution of the sequential algorithm to condition the comparators to scan symbols in parallel but in each of the blocks sequentially and cause matching sequences and nonmatching sequences of symbols to be stored in the array. The parameters i and j are selected to limit the number of comparators required to achieve a desired degree of efficiency in executing the algorithm based upon a trade-off of algorithm execution speed versus hardware cost.  A priority encoder calculates from signals output by the slice units each j,i address in which a matching sequence is identified, but it outputs the address of only one (such as the smallest) of these addresses.

IPC: D06F37/40
Filed: 1994-09-30
Abstract: A drive system for producing agitation and spin in an automatic washing machine incorporates a transmission assembly including a plurality of interengaged transmission elements located within a transmission housing. During agitation, the transmission housing is braked and the transmission elements convert input rotary drive from a motor to oscillatory drive of an output shaft. During spin, a cam member carried by one of the transmission elements automatically shifts a stop element into engagement with the transmission housing. This maintains the transmission elements in a predetermined orientation, prevents relative rotation between each of the transmission elements and the transmission housing and causes the entire transmission assembly to rotate in unison which results in rotation of the output shaft. Since the transmission elements are maintained in the same predetermined orientation during each spin, the entire transmission assembly can be effectively counterbalanced to minimize unbalancing of the system and reduce vibrations during operation.

A low voltage diode creates a dead band such that two high voltage start module transistors are never on at the same time. The high voltage module contains two high voltage blocking diodes which protect the laser gyro active current control circuitry during start up. Two small ballast resistors and a parallel 10 times voltage multiplier generate at least a 2500 VDC output.  The high voltage start circuit is contained within a laser gyro housing and is configured to have a volume less than the volume of the ring laser gyro block.
