Title: Liquid aspirating pipette and dispensing system
Inventor: ALLEN TERRY W
IPC: G01N1/00
Filed: 1991-04-23
Abstract: ABSTRACT OF THE DISCLOSURE A manually operable, liquid aspirating pipette, and associated dispensing apparatus, are disclosed.  The pipette includes a manually operable aspirator arrangement which permits collection and aspiration of a liquid sample.  A pull-back mechanism is provided to facilitate convenient introduction of air into the pipette subsequent to aspiration of the liquid sample.  Notably, the pipette includes a secondary actuating member which permits operation of the pipette by the associated dispensing apparatus.  Thus, after aspiration of a liquid sample, the pipette may be positioned in the dispensing apparatus, with the apparatus operated to provide controlled, metered dispensing of the sample in the desired manner.

Patent CA-2044118-A1 (CA)
Inventor: KRAUSE EDWARD A
IPC: H04N7/50
Filed: 1991-06-07
Abstract: A method and apparatus are provided for processing digital video signals for transmission in a compressed form.  A set of pixel data is compressed without motion compensation to provide a first compressed video signal.  The pixel data is compressed using motion compensation to provide a second compressed video signal.  The data in the first and second compressed video signals is quantified.  A comparison is made to determine which of the signals contains the least data.  Successive sets of pixel data are sequentially compressed and quantified and the compressed video signal having the least data for each particular set is selected. The selected signals are encoded to identify them as motion compensated or non-motion compensated signals, and combined to provide a compressed video signal data stream for transmission.  Apparatus for receiving and decoding the signals is also disclosed.

Title: Multiplexed signal transmitting apparatus and multiplexed signal receiving apparatus
Inventor: YASUKI SEIJIRO
IPC: H04N7/00
Filed: 1991-07-18
Abstract: Abstract of the Disclosure A multiplexed signal transmitting apparatus of this invention can transmit a first image signal, which is for a screen longer in the lateral direction than a screen obtained by a conventional television signal, by converting it to a signal that can be reproduced by a receiver of a conventional scheme.  A first encoder limits the band of the first image signal to provide a first component, and compresses the first component in the vertical direction, thereby converting the first image signal to a second image signal corresponding to a first portion of the screen of the conventional television receiver on its vertically central panel.  A second encoder compresses a second component, obtained by removing the first component from the first image signal, in the vertical direction, and encoding the frequency of the compressed second component to be a third image signal which can be multiplexed on second portions of the screen of the conventional television receiver on its upper and lower panels which are different from the first portion.  A motion detector detects image motion data by using the second image signal, controls a constant of a coefficient multiplier based on the motion detection signal, and controls the level of the third image signal.  A switch and an adder output the third image signal which is level-controlled to correspond to the upper and lower panels of the

Title: Sensor delivery device
Inventor: BERTAUD FRANCOIS X
IPC: A61M25/01
Filed: 1991-07-23
Abstract: SENSOR DELIVERY DEVICE                          Abstract of the Disclosure A device for storing and delivering a sensor through a catheter. A sensor delivery device (10, 10') includes an elongate tube (20), which is attached to a rigid housing (22, 22'). A sensor (12), stored within a sterile environment comprising an interior of the sensor delivery device, has an attached signal line (16) that extends along the longitudinal axis of the delivery device and through its proximal end.The proximal end is open when the sensor is in its stored position. An eversiblesheath (34) extends between the rigid housing and the signal line, sealingly separating the sterile environment (48) in which the sensor is stored from the open end of the rigid housing. To use the sensor, the signal line is moved into the rigid housing, causing the eversible sheath to turn inside out as the sensor is advanced through the catheter into its use position. The protection afforded by the eversible sheath permits the sensor to be withdrawn through the catheter and then reinserted without introducing contamination. A probe stop (54) abuts an inner surface of a catheter fitting (17), precisely controlling the distance that the sensor extends beyond a distal end of the catheter.     R MA/kao/klp
Patent CA-2049043-A1 (CA)
Title: Immobilized oligo-nucleotide probes and uses therefor
Inventor: COLLINS MARK L
IPC: C12Q1/6813
Filed: 1990-03-06
Abstract: The invention is a method of detecting nucleic acids in a sample using oligonucleotide probes which are noncovalently bound to solid supports for rapid, sensitive, hybridization assays. The method involves coating the support surface with a polynucleotide and then hybridizing a specific capture probe for each analyte to the polynucleotide by way of a short tail of the complementary polyunucleotide. The immobilized probes are used to capture nucleic acid targets out of complex specimens for nonisotopic detection without the need for prior cell culture or purification of the target nucleic acids. A panel of tests can be run on each specimen simultaneously, a format that conserves precious samples. The assay can be readily automated, and can be conveniently run in a manual fashion on large numbers of samples in two to three hours.

Below the bar code second and third plies are attached to the first ply adjacent their top edges, with the bottom edges of all of the plies substantially in alignment. The adhesive attaching these plies is staggered so that at no point along the form is there adhesive more than one layer thick. The adhesive may be repositionable adhesive, or permanent adhesive. With permanent adhesive it is desirable to provide fine perforations in the second and third plies just below the adhesive attachment of them to the first ply.      The first ply is preferably carbonless CF paper, the second ply carbonless CFB, and the third ply carbonless CB.

Inventor: TULAI ALEXANDER F
IPC: H04L27/14
Filed: 1992-05-21
Abstract: A class message receiver that in one embodiment can be implemented in a Digital Signal Processor.  An FSK demodulator takes input linear samples of the signal and filters them with a bandpass filter which does an upsampling to increase the sampling rate from 8,000 Hz to 24,000 Hz, which results in 20 samples at the output of the bandpass filter for each incoming data bit.  The amplitude of the signal/samples at the output of the bandpass filter is adjusted by an automatic gain control (AGC) circuit and the resulting samples (for convenience referred as sample (t), where t is a discrete moment in time) are processed along two different paths designed to estimate the likelihood of the input signal encoding a mark (mark estimation path) or a space (space estimation path).

Title: Neutralizer valve for a downhole pump
Inventor: DOWNING DONALD R
IPC: F04B47/00
Filed: 1992-05-28
Abstract: ABSTRACT OF THE DISCLOSURE    A neutralizer valve that is for use in conjunction with one or more reciprocating pumps of a tubing string that is operated in an oil well for recovery of crude oil.  The neutralizer valve takes the place of a regular traveling valve in a rod pump,  which includes a drag plunger for passing a crude and natural gas mix therethrough  on  a  down  stroke  of  the  tubing  string.    The neutralizer valve includes a guide barrel that connects into the rod pump plunger and contains a ported seal stem that is arranged to move up and down therein.  The ported seal stem includes a keyed rod as its upper end that is for fitting to travel up and down in a keyway that is formed through a ported disk which is arranged across the guide barrel interior.  The ported seal stem includes a collar formed around its mid-section, the undersurface of which collar is a valve face that is for engaging, so as to seal against a seat that is maintained in the guide barrel.  Which ported seal stem is ported below the collar into a center longitudinal passage that opens at the stem bottom end face.   The ported seal stem bottom lend is threaded to receive a coupling collar that is turned thereover for connecting it to a drag plunger of the downhole pump. On an up stroke of the rod tubing string the valve closes, creating a void between it and a standing valve of a downhole pump.  On a down stroke, the stem collar valve face is moved off the seat, opening the valve to allow a fluid flow therethrough.
