Patent CA-2162197-A1 (CA)
Inventor: ANDERSON JEFFREY
IPC: G11C16/10
Filed: 1995-11-06
Abstract: An interface system for communicating between a programmable device, such as a hearing assisting device, and a programmer unit employs a circular shift register and a memory.  Upon initialization the memory contents are loaded in the circular shift register and cycled through so that each bit is exposed to the programmer unit for verification or change.  After a complete cycle through the shift register the program is fed back to the memory where it is used to control the transfer function of the hearing assisting device.  By use of this circular shift register only two connections to the programmer unit are required, thereby minimizing the mechanical size of the connector needed to connect the programmer unit to the hearing assisting device, which may be an in the ear device.  A low voltage version of the interface system uses current sources and a high voltage version of the interface system, such as used for a remote controller, uses impedances and a voltage source.

Abstract: A method for improving the efficiency of horizontal wellbore cleanout of a horizontal wellbore drilled from a vertical wellbore, having a perforated liner cemented across the horizontal wellbore.  The method includes running a coiled tubing into the horizontal wellbore.  A first cleanup fluid is injected down the coiled tubing and a second cleanup fluid is injected down an annulus formed by the coiled tubing and the wellbore.  The injection rates of the cleanup fluids in the coiled tubing and the annulus are balanced.  The coiled tubing is moved back and forth over the horizontal wellbore.

Patent CA-2165147-A1 (CA)
Inventor: KOMATSU MASAKI
IPC: H04Q3/62
Filed: 1995-12-13
Abstract: In an inter-PBX routing apparatus, calls from channels of different service categories to a destination are normally carried by a first route.  A controller determines the available bandwidth remaining in the first route, classifies the channels as a first or second category if they cannot or can tolerated delays when establishing an alternate route, respectively, or a third category if they do not require the second route when the first route is overflowed.          A second route is established on a pre-assigned basis when the bandwidth of at least one idle channel of the first category is greater than the available bandwidth and on a demand-assigned basis in response to a request from a channel of the second category having a bandwidth greater than the available bandwidth.  When the second route is established, the controller controls a switch to establish a path between a requesting channel and the first route if the requested bandwidth is equal to or smaller than the available bandwidth or a path between it and the second route if the requesting channel is classified as the first or second category and the requested bandwidth is greater than the available bandwidth.          The controller returns a busy tone to the requesting channel if the requested bandwidth is greater than the available bandwidth.

Abstract: Methods of making a container strip in the form of a chain of interconnected preopened bags with openings preferably having longitudinal dimensions of at least about 1/64 inch is disclosed. The container strip provides greatly enhanced facility for bag registration and opening during packaging operations utilizing the improved container strip. Processes of forming a chain of preopened bags are also disclosed. Face (14) and back (5) plastic webs are fed along individual paths of travel to a common path (28). In one embodiments the webs are differentially tensioned while in their independent paths by stretching the face web, by rollers (18) more than the back web by rollers (20) such that the face web will retract longitudinally more than the back web upon release of the web tension. While so tensioned edge seals are formed between the webs to convert the webs into a tube and longitudinally spaced transverse seals are formed between the webs to delineate bottoms of bags. Transverse lines of weakness are formed in said back web to facilitate separation of bags from the remainder of the web during a subsequent use. Tension in individual bag sections of the face web is released by forming longitudinally spaced transverse separations of the sections and thereby producing a space between each contiguous pair of sections. In other embodiments, pairs of transverse lines of severance are formed in a front section of the webs and parts between the lines of severance are removed to form the novel bags without the need for differential stretching.

Abstract: Physically modified starch products are prepared using pressure and heat such as by extruding starting material starch which optionally can be admixed with gums and/or surfactants. The properties of the products can be adjusted by varying the moisture content of the materials in the extruder and the temperature and pressure at a die plate provided at the discharge end of the extruder. The screw elements in the extruder are selected with the goal of using enough mixing elements at the discharge end to keep the pressure in the extruder barrel as high as possible over a short distance. The physically modified starch products are made up of partially to fully cooked starch and some raw starch particles. They are highly dispersible in cold or hot water with hot or cold swelling viscosity.

Title: Base for a mold assembly
Inventor: NITSCHE REINHOLD ERNST
IPC: B29C49/48
Filed: 1996-10-17
Abstract: A base assembly for use as a part of a mold assembly for making containers comprises an adaptor, a base insert (or base plug), and a wear ring. The base insert is made from aluminum and has a lower surface positioned on a flat upper supporting surface of the adaptor. The base insert has an upper surface with a ledge surrounding a recessed contoured pattern in the base insert which pattern corresponds to a base of the container to be formed. The base insert has an annular side wall portion. The wear ring has an inner annular surface surrounding and engaging the annular side wall portion of the base insert to protect the annular side wall portion. The wear ring comprises a hardened wear resistant steel ring adapted to reinforce the base insert during formation of the container. The base insert and wear ring are secured to the adaptor by threaded fasteners that pass through threaded apertures in the adaptor, the base insert and the wear ring. By using an aluminum base insert the mass or weight of the base assembly is reduced and the heat transfer characteristics of the base assembly are improved reducing container forming cycle time. Further, the wear ring can be hardened by heat treatment which increases the strength of the wear ring above that of steel base inserts eliminating the need for stellite welding to reinforce the base insert.

Ces polymères possèdent un groupe hydrolysable cétoximinosilyle à chaque extrémité de chaque molécule et sont préparés par réaction d'un polymère liquide à terminaison hydroxyle avec un diisocyanate organique, afin d'obtenir un prépolymère à terminaison isocyanate. Le prépolymère obtenu est ensuite converti en polymère à terminaison mercaptan, soit par réaction avec un mercapto-alcool, soit par réaction avec un alcool ou une amine d'alkylène oléfinique, qu'on soumet ensuite à une réaction avec un dimercaptan. Quand le polymère à terminaison mercaptan est soumis à une réaction avec un vinyloximinosilane ou avec un vinylalcoxyoximinosilane, on obtient un polymère liquide à terminaison silane. Ces polymères possèdent des propriétés améliorées d'allongement, de résistance à l'humidité, à la traction et au déchirement lorsqu'ils sont utilisés dans des formulations adhésives, de revêtement ou d'étanchéité.
