Patent CA-2565868-A1 (CA)
Inventor: MARLIN FREDERIC
IPC: C06C9/00
Filed: 2005-05-11
Abstract: The present invention concerns a composition for a pyrotechnic compound that can be used as a thermal fuse in a gas generator comprising a pyrotechnic charge, said pyrotechnic compound having a self-ignition temperature that is lower than that of the pyrotechnic charge of the generator so as to be capable of initiating combustion of the pyrotechnic charge in the event of abnormal heating of the generator before said pyrotechnic charge reaches its self-ignition temperature. This composition is characterized in that it can be metered out and deposited in the form of an adhesive onto any appropriate support of the generator.

Abstract: The present invention relates to the production of original jewelry master model parts, in virtually any rigid material, assembling them in a mosaic style on a base and the production of molds to produce duplicate copies of the form and details of the assembled parts in a thin thermoplastic sheeting that is then cast in a selected metal using the well documented 'lost wax process', in order to produce a very light weight copy of the master model parts.     The 'lost wax process' uses a master model of a massive material and specialized molds of it, in order to produce duplicate copies of it in an expendable material that are invested in a mold filled with a slurry of a ceramic based refractory material, the mold is placed in a high temperature furnace that eliminates the expendable pattern and creates a cavity within the mold that is then filled with molten metal, which, when solidified produces a massive duplicate copy of the master model.     The production of light weight jewelry items using to-day's conventional jewelry production methods would entail producing each model part separately, refinishing and assembling the different parts using a selected soldering method, a step that is virtually impossible to accomplish without leaving unattractive seams that will tend to produce oxydation stains after a short period; labour costs would be high.     The expendable pattern material generally used in conventional production methods is made up of a wax based product that has a granular surface, which is reproduced in the metal casting and must be eliminated in the finishing steps of production whereas the cast part of the invention uses a vacuum formed thermoplastic sheeting that reproduces a surface equal to that of a pane of glass that results in an absolute minimum finishing requirement of the metal casting and produces a far more attractive finished product at a much lower overall cost.

Abstract: The present invention is directed to a manual bulk liquid pump control and distribution system (10) that utilizes a single- handle manual formation for direction of flow and speed, along with providing a neutral position for standby. The system can be operated at a rate of 0 to 250 gallons per minute and be reversed with a single motion of the operating handle. The pump operates in one direction at a fixed RPM, resulting in longer pump life and safer operation. For added safety, the system utilizes the pump's relief valve for both discharge and suction operation. It has the ability of sucking the liquid out of the lines and hoses after each transfer operation. This system has an aluminum flow-reversing valve or two-way valve (18) at the center of the design. This valve allows the flow of the product to be precisely controlled in either direction, along with the flow rate and pressure.

Title: Active set update (asu) with high speed downlink shared channel (hs-dsch) information
Inventor: PIRSKANEN JUHO
IPC: H04W76/04
Filed: 2005-09-27
Abstract: Because the current RRC: ACTIVE SET UPDATE message presently used in soft handover does not contain HS-DSCH related information, which could be utilized for a Serving HS-DSCH cell change, a separate Radio Bearer Control procedure is needed between the UE (10) and the RNC (20) for carrying out the Serving HS-DSCH cell change. Should HS-DSCH related information - applicable to Serving HS-DSCH cell change - be added to the RRC: ACTIVE SET UPDATE message (32), an unnecessary Radio Bearer Control procedure is avoided, and the drawbacks of the current method are overcome.

Title: Rolling mill product handling system
Inventor: ELDREDGE MICHAEL
IPC: B21B39/18
Filed: 2007-05-01
Abstract: A product handling system comprises a support structure defining a pair of stationary inverted first channels with downwardly facing open sides. At least one cylindrical drum is interposed between each of the first channels and an underlying receiver. The drums are rotatable about their axes, with their surfaces arranged to close the open sides of the respective first channels. The drum surfaces are interrupted by second channels, with the first and second channels and the drum axes being arranged in a parallel relationship. Successive product lengths are alternately delivered longitudinally into one and then the other of the first channels. The drums are rotated about their axes resulting in the thus delivered product lengths being sequentially: (i) temporarily retained in the first channels by the rotating drum surfaces; (ii) deposited from the first channels into the second channels when the second channels rotate into radial alignment and communication with the first channels and (iii) downwardly deposited from the second channels to the receiver when the second channels rotate to discharge positions over the underlying receiver.

The transfer device is external to the body and has a lumen for storing at least one treating element, the treating element being moved from the transfer device into the catheter by means of pressurized fluid. A system for detecting whether the treating element resides at a targeted location along the lumen of the transfer device comprises a pressure transducer in fluid communication with the lumen of the transfer device so as to be capable of measuring the fluid pressure at the targeted location of the lumen. Circuitry is provided for comparing the measured pressure to a reference pressure corresponding to the pressure at the targeted location when the treating element is stored at the targeted location under fluid pressure. A signal generator provides a signal when the measured pressure differs from the reference pressure by more than a predetermined percentage.

Title: Electromagnetic surveying for resistive or conductive bodies
Inventor: ANDREIS DAVID
IPC: G01V3/12
Filed: 2006-02-03
Abstract: A method of analysing electromagnetic survey data from an area of seafloor (6) that is thought or known to contain a resistive or conductive body, for example a subterranean hydrocarbon reservoir (12), is described. The method includes providing horizontal electromagnetic field data obtained by at least one receiver (125) from at least one horizontal electric dipole transmitter (22). Horizontal gradients in the electromagnetic field data are determined for a first component of the electromagnetic field data along a first direction and for a second component of the electromagnetic field data along a second direction. The first and second components can be the electric field along the first and second directions, or the magnetic field perpendicular to the first direction and second directions. The gradients are then combined to provide combined response data. Because the combined response data are relatively insensitive to the transverse electric (TE) mode component of the transmitted signal, the method allows hydrocarbon reservoirs to be detected in shallow water where the TE mode component interacting with the air would otherwise dominate.

Abstract: The invention relates to a device and a method of use that will allow a medical professional to change a patient's tracheostomy dressing (24) in an efficient manner that will cut down both the professional's and patient's discomfort. In the preferred embodiment of the invention, the device has a body (30) that includes a handle (32), a shoulder (34) and two prongs (36a, 36b); however, the handle (32) is optional. The entire lower surface (40) of the body (30) has a concave curve in one embodiment. The handle (32) extends and ends at the shoulder (34). On the end of the shoulder (34), extending away from the shoulder (34), and curving in an upward direction relative to the shoulder (34), are the two prongs (36a, 36b). The prongs (36a, 36b) are parallel to one another and form a "U"-shape, the distance (D) of which is wider than the distance of the diameter of a trach tube. The prongs (36a, 36b) are designed to fit within the trach drainage sponge (24). This allows the user of the device (30) to insert the sponge (24) in a simple, smooth manner.  After successfully inserting the sponge (24) into position, the professional will remove the device (30), leaving behind the sponge (24).
