Patent CA-2313499-A1 (CA)
Title: Electrical connector with component package
Inventor: BELOPOLSKY YAKOV
IPC: H01R24/62
Filed: 2000-07-10
Abstract: An electrical connector such as a modular jack receives a component package having a plurality of first conductive elements and at least one electrical device electrically coupled to the first conductive elements. The electrical connector has an insulative housing with an interior and an insulative insert with a forward portion and a rear portion. The rear portion defines a recess for receiving the component package therein, and the insert is mounted within the interior of the housing. A plurality of first contacts are mounted to the forward portion of the insert for electrically contacting conductors in a mating connector inserted into the electrical connector. Each first contact extends from the forward portion of the insert to the recess and terminates at a termination in communication with the recess. The termination of each first contact electrically contacts a corresponding first conductive element of the component package as received in the recess.

Patent CA-2316866-A1 (CA)
Title: Communication system using a compressed connection
Inventor: GRUTTER HENDRIKUS J
IPC: H04Q11/04
Filed: 1999-10-27
Abstract: In a communication system comprising a number of networked PBX's often compression connections are used for interconnecting such PBX's. In a PBX (3), a plurality of source signals is compressed by a compression processor (32) and subsequently multiplexed by a multiplexer (34). The multiplexed signal is transmitted to a second PBX (5) where it is demultiplexed by a demultiplexer (36) and decompressed by a decompression processor (40). Due to the compression performed on the source signal, the quality of the reconstructed speech signal in the second PBX is somewhat deteriorated. In order to improve the quality of the reconstructed source signal, it is proposed to make the compression ratio dependent on the aggregate bitrate of the source signals to be transmitted over a particular transmission link.

Said nucleation device comprises means in the shape of a spray tip for high speed spraying (11) of compressed air and in the shape small diameter nozzles (13) for spraying pressurised water into the air stream. In one embodiment, the nucleation device is in the form of a mini snowmaker (52).

Title: Oral immunology using plant product containing hepatitis surface antigen
Inventor: ARNTZEN CHARLES J
IPC: A61P37/04
Filed: 2000-10-12
Abstract: A method for obtaining an immune response to hepatitis B surface antigen (HBsAG) by feeding the antigen in a plant material to an animal that is immunoreceptive to the HBsAg. It has now been discovered that the animal may be made immunoreceptive to HBsAg either by administering the plant material containing HBsAg in conjunction with a suitable adjuvant or by prior primary immunization. When the animal is made immunoreceptive by a prior , e.g.  primary, immunization, an immune response to HBsAg may be boosted in the animal by feeding the animal the plant material containing the HBsAg. For example, an animal, e.g. a human, that previously had a positive response to primary immunization against hepatitis B, can have a booster response to HBsAg by feeding the animal the antigen in a plant material. The plant material is a substance comprising a physiologically acceptable plant material, especially potatoes, containing hepatitis B surface antigen (HBsAg). The HBsAg in the plant results from expression by the plant of HBsAg due to genetic alteration.

IPC: E21B21/00
Filed: 1999-03-26
Abstract: Pompe à déplacement positif comprenant de multiples éléments de pompage comportant chacun un appareil sous pression présentant une première et une deuxième chambres et un élément de séparation située entre la première et la deuxième chambres. Cette première et cette deuxième chambres possèdent une communication hydraulique servant à recevoir et à évacuer le liquide et les éléments de séparation se déplacent à l'intérieur des appareils sous pression en réaction à une différence de pression entre la première et la deuxième chambres.

Ces soupapes d'aspiration et de refoulement permettent au liquide de s'écouler alternativement vers l'intérieur et vers l'extérieur des premières chambres. Une unité de commande hydraulique fonctionne de façon alternée afin d'alimenter les deuxièmes chambres en liquide hydraulique et d'évacuer ce liquide hors desdites chambres, de sorte que le liquide évacué hors des premières chambres est exempt de pulsations.
Patent CA-2331203-A1 (CA)
Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N21/647
Filed: 1993-03-25
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal apace diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data stream respectively.      Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability.

Title: Anti-backlash nut assembly
Inventor: ERIKSON KEITH W
IPC: F16H25/20
Filed: 1999-05-26
Abstract: An anti-backlash mechanism is described in the form of a pair of nuts (14, 16) or nut halves with internal threads complementary to the threads on a lead screw (10). The mechanism is translated by rotation of the screw. One of the nuts (14) has an outer cantilevered wall (31A) with inner gear teeth (30A) which engage outer gear teeth (30B) on the other nut. Rotation of one nut with respect of the other nut tightens or loosens an abutting frictional rotation-opposing resistance of an elastomeric washer (52) compressed between the two nuts. The compressed washer exerts a bias force against the nuts opposing axial forces exerted by the lead screw against the flanks of the nut threads.

IPC: B67D1/00
Filed: 1999-10-15
Abstract: A bottled water/tap water cooler and compact oxygen generator system (100) combined within a single housing structure (10). The oxygen generator (100) includes an air compressor (300) for generating compressed air having into dual molecular sieve beds (120, 130) one at a time. As a first molecular sieve bed (120) absorbs nitrogen, up to approximately 95 % pure oxygen is allowed to pass therethrough to a flow meter (50) and into a diffuser (30) which passes the oxygen into a purified drinking water reservoir (20) supplied by the bottled water or filtered tap water. After the first molecular sieve bed (120) is full, the second molecular sieve bed (130) activates and starts absorbing nitrogen while allowing oxygen to pass therethrough, simultaneously, nitrogen is vented from the first molecular sieve into the atmosphere. The first and second molecular sieve beds alternate with one another allowing the system to run continuously by using timer controlled dual 3-way valves (113, 115).
