Patent CA-2172094-A1 (CA)
Title: Coil body
Inventor: LEHMANN EBERHARD
IPC: H01F5/04
Filed: 1996-03-19
Abstract: A coil body (1) with connecting pins (3) injected in a lower flange (2), said pins being windable with coil winding wires, is characterized in that ends (3a) of the connecting pins to be injected are provided with a circular embossing (4). The embossing is applied to the material by a circularly cylindrical needle (10) polished to a high gloss. Producing embossing with a very low depth of roughness effectively eliminates the tin dust that would otherwise be created in the shaping process, thus drastically reducing contamination of the injection tools. In addition, this embodiment definitely increases the force required to pull out the pins.

Title: Method for dispensing liquid from a multi-dose cartridge
Inventor: BUTLER KEVIN H
IPC: B65D83/00
Filed: 1994-09-29
Abstract: A method for accessing and dispensing liquid from a multi-dose cartridge of the type having a vent/draw system is disclosed. The method employs using a cartridge interface system having a needle for accessing the cartridge. The needle is attached to a piston, which is in turn connected by means of a crank and linkage to a gear motor. This gear motor drives the piston effecting the motion of the needle. The action of the gear motor is responsive to signals from various sensors, which permit a fully automated method of accessing and dispensing liquid. In the method, the cartridge is accessed when its presence is detected by the cartridge interface method. Liquid is dispensed continuously until the absence of liquid is detected, at which time the cartride is disabled by disengaging the vent/draw system and disconnected the cartridge interface system from the cartridge.

Title: Railway crossing collision avoidance system
Inventor: WELK JAMES E
IPC: B61L29/24
Filed: 1996-09-09
Abstract: With  the  vehicle  anti-collision  system  of  the present invention, road vehicles in the vicinity of a railway crossing are alerted as a train approaches the crossing.   A signalling device operating in conjunction with a GPS receiver located in the train emits a signal to a receiver located at the  railway crossing to provide an indication of the  rail vehicle's location with respect to the railway crossing.   The signal  is  sent  continuously  at  predetermined  intervals  to provide the railway crossing with sufficient data to estimate the  velocity and time of  arrival  of  the  train or  railway vehicle at the crossing.   The railway crossing processes the information and transmits an alarm signal to approaching road vehicles as the rail vehicle approaches the crossing.   The signal emitted by the crossing is received at the road vehicle which provides various levels of alarms depending on how close the rail vehicle is to the crossing.

Title: Covalent dimers of kit ligand and flt-3/flk-2 ligand
Inventor: NOCKA KARL H
IPC: A61P7/06
Filed: 1995-03-28
Abstract: A modified form of KL, the ligand for the c-kit proto-oncogene, has been prepared wherein the protein is stabilized by an intermolecular covalent linkage. The protein can be prepared by expression of a recombinant protein wich is dissolved in denaturant and refolded under conditions resulting in a disulfide linked dimer. Examples demonstrate the purification and characterization of this disulfide-linked cysteine dimer kit ligand (KL-CD) which contains at least one intermolecular disulfide bond and has at least ten-fold greater activity in promoting cell poliferation than native, non-covalently linked KL, as measured in in vitro assays. The figure shows the proliferative activity of murine KL,NC, murine KL-CD, murine KL-Ig fusion, and human KL-Ig fusion on an MO7e cell line.
Patent CA-2193659-A1 (CA)
Inventor: MARCHETTO ROBERT F
IPC: H04B7/005
Filed: 1994-06-30
Abstract: Une pluralité de symboles pilotes (176) est ajoutée à une pluralité de symboles de données pour constituer des suites de trames (170) modulées au moyen d'un émetteur (64). Le signal modulé émis subit une perte de données imputable au simple fading et aux interférences entre voies et entre destinataires multiples. Le signal reçu est démodulé par un récepteur (74) puis traité pour délivrer un signal comprenant les symboles de données (82) et un signal pilote comprenant des symboles pilotes (86). Le signal de données est temporisé (90) assez longtemps pour permettre l'évaluation de la réponse impulsionnelle canal applicable à la séquence des blocs de symboles pilotes (98), de préférence en utilisant les blocs de symboles pilotes qui précèdent mais aussi qui suivent les symboles de données dans la trame à traiter. La réponse impulsionnelle canal évaluée, applicable à la séquence des blocs de symboles pilotes, est rangée dans une mémoire tampon (102), puis reprise par un interpolateur (92) qui détermine, pour chaque symbole de données, une évaluation interpolée de la réponse impulsionnelle canal (104) en fonction des symboles pilotes et de caractéristiques canal déterminées. L'application, à la séquence des symboles de données du signal de données temporisé, de la réponse impulsionnelle canal évaluée par interpolation permet de décoder (108) les données en compensant le fading et les interférences.

Patent CA-2212886-A1 (CA)
Title: Spray pipe system
Inventor: FERBER KLAUS
IPC: B08B9/34
Filed: 1996-03-07
Abstract: A cleaning apparatus consists of a pipe conduit (10) which is reduced or expanded by the provision of several groove-like recesses (21) and/or outwardly bulged portions (22). Boreholes (26, 26') are provided on the flanks (25, 25') of the groove-like recesses or the outwardly bulged portions, wherein the longitudinal axes (27) of the bores form a right angle with the curved side surfaces of the pipe wall so that the cleaning medium can exit obliquely from the pipe conduit in bundled cleaning streams. The angle over which the cleaning streams extend is determined by the position of the boreholes in the curved side surfaces and the slope of the flanks. By adjusting the angle of incline and through a variable positioning of the boreholes, it is possible to obtain different spray patterns, which allow an optimal distribution of the spray medium and a uniform wetting of the surfaces to be cleaned. Since the longitudinal axes of the bores are located at right angles to the pipe wall, it is a simple matter to create the bore profile utilizing a laser. The cleaning apparatus is preferably used in a transport apparatus for bottles. In this case, the pipe conduits are arranged as exchangeable units and are positioned between the two reaches of the transport bands.

Patent CA-2217796-A1 (CA)
Title: Water heater with co-located flue inlet and outlet
Inventor: BOCK JOHN C
IPC: F24H9/02
Filed: 1997-10-28
Abstract: A blower draws air through an inlet duct from outside a building or dwelling and injects air and fuel into a sealed combustion chamber where they are ignited and burned within a ceramic crucible within combustion chamber. The pressurized combustion gases flow up an exhaust stack in the water tank of the water heater. The exhaust stack is connected to a vent that extends through a building outside wall. The vent is surrounded by the inlet duct which has an opening spaced from the outlet vent so that air from the vent is not captured by the inlet. The combustion chamber and the heat exchanger are sealed from the interior of the building and both the air inlet to the blower and the air outlet from the heat exchanger freely communicate to the outside of the building. A timer within the controller operates the blower for a period of time after the fuel supply to the burner has been shut off. This operation of the blower assures that residual heat within the combustion chamber is transferred to the water in the tank.

Title: Method and apparatus for power control in a communication system
Inventor: BRUCKERT EUGENE J
IPC: G01S11/06
Filed: 1997-01-03
Abstract: Power control in a spread spectrum communication system takes place by determining a speed of a remote unit (405) and assigning as a power-control threshold a target threshold based on the determined speed (410). An instantaneous threshold value is created (415) based on frame-quality information and the target threshold. An energy of a power-control group transmitted (430) from a remote unit is compared to the instantaneous threshold value and a power-adjustment command is determined. The power-adjustment command is transmitted to the remote unit instructing the remote unit to adjust its power accordingly.
