Patent CA-2203520-A1 (CA)
Inventor: STRATTON RICKEY LEE
IPC: B60R21/26
Filed: 1996-09-16
Abstract: A gas generator (10) utilizes at least three segregated propellant container/combustion chambers (22, 32 and 34), each having a plurality of nonazide propellant grains (20, 36 and 38) therein, and an igniter (16) for igniting only the propellant grains (20) located within the first combustion chamber (22).

Title: Data modulating and demodulating system and data processing method therefor
Inventor: SAKAJIRI NORIYASU
IPC: H04L29/06
Filed: 1997-05-27
Abstract: In  a  modulation  and  demodulation  system  for exchanging   data   between   a   terminal   unit   and   a communication  network,  when  the  terminal  unit  is  not connected,  in  response  to  data  reception  from  the communication network,  the reception data is temporarily stored in a memory.  When the terminal unit is connected, the data is read out from the memory to transfer to the terminal unit.  By this, even when the terminal unit is not connected to the data modulation and demodulation system, disposal of the reception data is not required.   On the other hand,  upon storage of the reception data to the memory, by storing the data compression, reduction of the memory capacity becomes possible.

Patent CA-2215422-A1 (CA)
Title: Process and seal for minimizing interzonal migration in boreholes
Inventor: BOYD JOHN WESLEY
IPC: E21B33/138
Filed: 1997-09-15
Abstract: A process and a material for use in sealing casing lining in a borehole is taught. The process includes the placement of a bitumen sealant material in a position between the casing tube and the wall of the borehole to be maintained in this annulus by means of a retaining devise such as an external casing packer or with the placement of a retainer made of cement grout and situated at the lower end of the casing tube. The bitumen sealant material prevents the passage of fluids vertically through the borehole. The sealant material remains viscous over time and can flow to fill voids which may occur in the rock formations adjacent to the borehole, or in the steel casing of the casing tube. To improve the sealing capabilities of the bitumen material a measured amount of fine grain weight material can be added to the bitumen to increase the density of the sealant material and thereby increase the hydrostatic pressure that the column of bitumen sealant will exert on the bottom and the walls of the borehole.

Title: Radiographic contrast material injector
Inventor: BAILIN STEVEN J
IPC: A61B6/00
Filed: 1996-04-19
Abstract: An angiographic injector system (10) includes a motor driven pump (18) which delivers radiographic contrast material to a catheter (30) at a variable flow rate which is interactively controlled by a user.  Operation of the pump (18) is controlled by the user, through a user actuated remote control (14). The angiographic system (10) also includes a manifold (26) and a valve which selectively connects either a syringe pump (18) or a low pressure system (38) to a catheter (30) which is inserted into a patient. The valve is normally biased to a state which connects the low pressure system (38) to the catheter (30) for pressure monitoring, saline flushing, or aspirating functions. When an injection is to be made, the valve automatically switches so that the low pressure system (38) is disconnected and not exposed to high pressure, while the syringe pump (18) is connected through the manifold (26) to the catheter (30).

Patent CA-2219726-A1 (CA)
Inventor: CHEN FUNG-JOU
IPC: A61F13/15
Filed: 1997-11-19
Abstract: Absorbent articles containing absorbent cores of fluff pulp frequently contain wrinkles in the absorbent core that run from side to side of the article, typically normal to the machine direction in the manufacturing process. Side-to-side wrinkles are deleterious in that they provide large flow channels for urine or other body fluids to escape to the edge of the article. Frequently, such wrinkles are present after manufacturing, before the article has been folded or worn. The cause of the wrinkles is believed to be due to natural instabilities during compression of the fluff pad shortly after it is formed. Means for reducing cross-directional wrinkles include the use of grooved, drilled, or patterned compression rolls to densify the fluff pulp while providing opportunities for reduced in-plane displacement during compression or, if in-plane displacement does occur, providing paths for cross-directional displacement as well as machine-direction displacement so that continuous CD wrinkles cannot form. The use of large diameter rolls with soft rubber covers can also be used.

Inventor: PLUNKETT TOM P
IPC: F16J15/08
Filed: 1997-11-19
Abstract: A metallic gasket for use in an internal combustion engine has seals around the gasket openings which are formed by a two-step coining operation plus a folding operation. The gasket has a base plate including a folding portion located between an edge of an opening and a fold line. A channel and a reduced thickness portion are formed in the folding portion by a first coining operation. The channel is spaced from the edge of the opening and spaced from the fold line. Next the folding portion is folded back onto the base plate of the gasket. Finally, a second coining operation takes place to flatten the folded seal to a final thickness and produces material flow between the base plate and the folding portion.

Title: Statistical tolerancing
Inventor: ATKINSON ROBERT E
IPC: G05B19/418
Filed: 1996-06-21
Abstract: A process of establishing valid sta-tistical dimensional tolerance limits for de-signs of detail parts that will enable accurate prediction of an economically acceptable degree of non-conformance of a large flexi-ble end item assembly, having a set of pre-determined dimensional tolerances, made from the detail parts, wherein the detail part tolerances are enlarged substantially com-pared to tolerances that would be necessary using an arithmetic "worst case" approach to remain within the end assembly toler-ances while remaining within preestablished stress limits of the parts. A preferred assem-bly sequence for assembling the parts into the assembly is selected and validated. Lo-cations, numbers arid size of coordination features to be machined in said detail parts are selected, by which the parts are located relative to each other and fastened together to form the assembly. Individual part statis-tical dimensional tolerances are established as a fabrication requirement for the parts that enable the parts to be economically produced and assembled into assemblies that meet the predetermined assembly dimensional toler-ances. The individual part statistical dimensional tolerances are broader than con~ ntional tolerances that are established to ensure acceptable assemblies when parts are assembled at the extremes of their tolerances. stac~  in a worst case manner. The parts are produced to the individual statistical dimensional tolerances in a capable process, having a Cpk ~ual to at least 1.0, while holding the mean values of the statistically determined dimensions of the individual parts to within a predetermined percentage of the nominal dimension. The end item is assembled in accordance with the preferred assembly sequence by locating the parts relative to each other by reference to the coordination features. The properly located parts art fastened together as located, using the coordination features as the primary determinator of assembly configuration.     configuration.
