Inventor: ROTTER TERRENCE M
IPC: F02M37/04
Filed: 1994-08-23
Abstract: A fuel pump body has a chamber with one wall formed by an external diaphragm having a stem connected thereto.  The fuel pump body is attached to the outside of a valve cover for a gasoline engine and the valve cover has a depression that forms an enclosure for the diaphragm.  The stem passes through an aperture in the valve cover and connects to a lever pivotally attached to the underside of the valve cover.  The lever engages the valve rocker arm of the engine and produces reciprocal  movement of the stem and diaphragm as the rocker arm moves. The reciprocal movement of the diaphragm alternately draws fuel into the chamber through the inlet and that expels fuel through the outlet.

Patent CA-2134958-A1 (CA)
Inventor: MEASURES RAYMOND M
IPC: G02B6/34
Filed: 1994-11-02
Abstract: The spectral and temporal form of radiant energy traveling down optical fibers is important in many fields, including communications and sensing. The spectral distribution and centre wavelength of short optical pulses is of particular importance. In the communication field the information carrying capacity of an optical fiber can be limited by the dispersion experienced by short pulses as they propagate along an optical fiber. Chirped fiber optic intracore Bragg gratings can be used to compensate for this dispersion. However, a grating with a different degree of chirp would be required for each particular communication system. We have invented a method and apparatus for controlling the detailed strain field imposed on a guided-wave Bragg grating. This precise control of the infra-grating strain distribution allows the grating to be tuned over a broad spectral range or chirped in a manner that permits it to compensate for a wide range of dispersion with or without a shift in the grating centre wavelength. In addition, precise control of the strain distribution along a grating can be used to manufacture a variety of spectral filters.

Patent CA-2140171-A1 (CA)
Title: Contact programmable wiring and cell array architecture
Inventor: KELLAM MARK D
IPC: H01L23/535
Filed: 1995-01-13
Abstract: Integrated circuits with architecture resembling a row-based gate array are prefabricated up to, and including, the metallic interconnection, and stocked.  To fabricate a prototype of an Application-Specific IC, a single application-specific mask is used to connect wires existing on a prefabricated IC with Top Level Vias (via-like connecting structures, TLV), upon which the prototype may be passivated, bonded, packaged, and tested.  For mass-production of an Application-Specific IC, a typical IC fabrication process is employed, using the same masks are used as for the prefabricated ICs, with the exception of the mask of vias for connecting the metal interconnection layers, which is modified to produce the same connections as those introduced by the TLVs added during the prototyping.  The single-mask-programmable aspect of the invention is facilitated by the general-purpose wiring channels (220) adjacent to rows of programmable  cells (211).  Channels (220) comprise wiring patterns (222A and 222B), each containing a grid of two levels of initially unconnected wires, positioned so as to facilitate using either conventional vias or the TLVs for connecting wires within each pattern, wires in a pattern to wires in an adjacent patterns, and wires in a pattern to wires in an adjacent programmable cell (211).  Programmable cells (211) are designed so as to facilitate implementing a set of different logical functions with appropriately positioned  conventional vias or TLVs.  As a result, the cost and time required for fabrication of a prototype are reduced, and the conversion to mass-production is simplified over typical methods used in prior art.

Patent CA-2147896-A1 (CA)
Title: Modular toy building system
Inventor: HARTMAN DAVID
IPC: A63H33/06
Filed: 1995-04-26
Abstract: The modular toy building system uses extruded foam rods which cooperate with foam cross connectors designed to receive up to four rods.  Each cross connector includes two connecting sleeves or tubes of a length for receiving and securing a foam rod either end thereof while leaving a central port unobstructed by the rods.  One sleeve has been deformed and inserted through the port of a second sleeve and positioned such that the ports overlap.  This produces a stable cross connector for cooperating and releasably receiving a foam rod in each end of a sleeve.  Preferably, sleeves which cooperate to form a cross connector have a securing gap passing axially through the sleeves, which gap forms part of the central port of each sleeve.  This gap can receive a pinning member joining two or more stacked connectors.  Preferably, the central port of each sleeve is oval.

Title: Method and apparatus for casting hollow fiber membranes
Inventor: MILLIKEN ROBERT DEANE
IPC: B29C48/32
Filed: 1993-12-03
Abstract: An automated system for casting hollow fiber membranes.  A coextrusion die (10) is rotated over a stationary coagulation bath. A computer (3) is used to control the motion of the die (10) to make a membrane of desired shape. The nozzle is oriented in a manner that will compensate for distortions that occur in wall thickness in the area of a bend. The nozzle's annulus is offset to make the leading portion of the annulus slightly thicker and the trailing portion thinner at the point where the fluids exit the nozzle, which results in a uniformly symmetric wall thickness.  The system includes sercomotors (1A, 1B, 1C), each of which is coupled to an associated position encoder (2A, 2B, 2C). The motors (1A, 1B, 1C) are controlled by a computer (3) via servodrivers (4) and an associated interface card. ALco included in the system are a tub (5) for holding a coagulation bath, bearings (6), carriage (7), screw drive (8) and rotary table (9).

Title: Pulse based cable attenuation measurement system
Inventor: BOTTMAN JEFFREY S
IPC: G01R31/02
Filed: 1995-11-29
Abstract: A pulse-based cable attenuation measurement system provides a measurement of attenuation characteristics of a cable over a wide frequency spectrum. A main test and troubleshooting unit of a cable test instrument applies stimulussignals via a selected one twisted pair in a LAN cable to a pulse receiver in a remote unit that in turn causes a pulse generator to produce a specified pulse of known amplitude and duration that is applied as a measurement pulse to a separate but adjacent twisted pair within the same bundle or cable. A measurement system analyzes the measurement pulse after it reaches the main unit and provides attenuation versus frequency information to determine whether the amount of signal loss due to attenuation in the cable is acceptable or not.
