Patent CA-2085890-A1 (CA)
Title: System and method for generating signal waveforms in a cdma cellular telephone system
Inventor: GILHOUSEN KLEIN S
IPC: H04L1/06
Filed: 1991-06-21
Abstract: A system and method for communicating information signals using spread spectrum communication techniques. PN sequences are constructed that provide orthogonality between the users so that mutual interference will be reduced, allowing higher capacity and better link performance. With orthogonal PN codes, the cross-correlation is zero over a predetermined time interval, resulting in no interference between the orthogonal codes, provided only that the code time frames are time aligned with each other.    In an exemplary embodiment, signals are communicated between a cell-site (12, 14) and mobile units (16, 18) using direct sequence spread spectrum communication signals. In the cell-to-mobile link, pilot, sync, paging and voice channels are defined. Information communicated on the cell-to-mo-bile link channels are, in general, encoded, interleaved, bi-phase shift key (BPSK) modulated with orthogonal covering of each BPSK symbol along with quadrature phase shift key (QPSK) spreading of the covered symbols.     In the mobile-to-cell link, access and voice channels are defined. Informa-tion communicated on the mobile-to-cell link channels are, in general, en-coded, interleaved, orthogonal signalling along with QPSK spreading.

Title: Stacked in-line insulation displacement connector
Inventor: BURKARD CHRISTOPHER J
IPC: H01R4/24
Filed: 1993-01-12
Abstract: An insulation displacement connector for interconnecting a variable number of wires in a stacked, in-line configuration. The connector includes a hollow body for receiving the wires, a metallic contact element located within the body, and a cover. In the primary embodiment, the body has front and rear walls each having three holes in a stacked, nonlinear arrangement. The stacking feature provides a more compact connector. All but two of the holes are obstructed by rupturable membranes which seal unused holes and thus provide greater flexibility with regard to the number of wires which may be reliably interconnected. The contact element includes shoulder contacts for receiving the upper wires, and leg contacts which extend beyond the shoulder contacts for receiving the lower wires. The cover advantageously has a plunger which forces sealant material throughout the body, and further has strain relief fingers and latching clips.

Patent CA-2093135-A1 (CA)
Inventor: LADANY IVAN
IPC: G02B6/42
Filed: 1991-05-07
Abstract: Means for coupling an electrooptical device, such as a semiconductor laser, to an optical fiber avoids heat-induced stresses that commonly result from joining methods employing welding, soldering, or catalytic adhesive compositions. In this invention, the electrooptical device (11) and fiber (12) are firmly mounted within separate elements, such as copper tubes (13, 14), by means of potting compound or the like, and after close end-to-end supported alignment of the device and fiber elements to obtain optimum light coupling, the assemblage is immersed in an electrolytic plating solution (34). Plating current is then applied and maintained until a sufficiently strong layer (19) of plating metal encompasses the tubular elements and thereby rigidly fixes the alignment of the device and fiber end at its optimum position. Since the plating operation proceeds in a substantially isothermic environment, there is no misaligning stress introduced which would otherwise degrade the coupling efficiency.

Title: Dna expression systems based on alphaviruses
Inventor: GAROFF HENRIK
IPC: C12N7/00
Filed: 1991-12-12
Abstract: Efficient protein production from cloned DNA in animal cells has been hampered by the lack of suitable expression systems. The requirements of such an expression system are (1) to produce functional or immunogenic forms of protein molecules in a wide variety of animal cells, (2) high efficiency and (3) technical simplicity.  The present invention is related to a technical solution to this problem. A DNA molecule encoding protein sequences is inserted into engineered variants of the cDNA of a positive stranded RNA  virus genome from alphavirus which then, via RNA transcription and transfection into tissue culture cells, is used to produce either chimaeric virus particles for immunization or recombinant virus for protein production. Because of optimized conditions of transfection and the nature of the virus replication the present system combines both simplicity and safety in terms of handling, efficiency in terms of level of protein and RNA production, as well as broad host range.

Title: Vertical bore hole system and method for waste storage and energy recovery
Inventor: ANDERSON JAMES S
IPC: E21B33/14
Filed: 1993-07-26
Abstract: ABSTRACT OF THE DISCLOSURE      Vertical bore holes are constructed for municipal sanitary landfills by drilling or otherwise excavating holes of large dimension to substantial depth, in virtually all known soil conditions however variable.  They can be excavated well below the groundwater table, then lined with an impermeable or other permanent liner.  This allows the landfill area to be much more efficiently used for the storage of various waste products.  Solid organic waste other than cellulosic can be anaerobically fermented to methane and compost.  A central core shaft is used as gas removal vent and conduit.  After methane generation and removal the resulting compost is removed for use as soil nutrients.  This system fully complies with the Environmental Protection Act and other regulations now in force in North America.  Air, soil, groundwater, and surface water pollution and contamination are eliminated as all waste storage is contained within its own environment below natural grade.

Abstract: In a structure for cooling an integrated circuit (IC), a hollow cylindrical member is mounted on a cold plate and receives a heat conductor therein.  The heat conductor is a cylindrical member which is closed by a flat plate at one end thereof.  Silicone gel fills a gap between the hollow cylindrical member and the heat conductor and allows the heat conductor to move due to the elasticity thereof.          When the cold plate is fixed in place on the IC which is mounted on a printed circuit board, the heat conductor moves in matching relation to the height and inclination of the IC.  As a result, the heat conductor and IC are brought into close contact with each other.  A compound intervenes between the heat conductor and the IC to enhance the close contact of the heat conductor and IC.

Title: Hybrid Gas Generator for Airbag Inflatable Restraint Systems
Inventor: SMITH BRADLEY W
IPC: B60R21/26
Filed: 1993-11-08
Abstract: A gas generator includes a chamber in which inert gas under high pressure is stored, a diffuser chamber, and a chamber containing a pyrotechnic heater and initiator.  Upon receiving an electrical signal the initiator fires igniting the pyrotechnic charge.  As pressure in the combustion chamber of the pyrotechnic heater rises and exceeds the storage chamber pressure, a plug in a shoulder covering the pyrotechnic nozzle orifice is unseated, subsequently rupturing a thin metal sealing diaphragm since the latter is unsupported for a pressure differential in this direction.  Hot gas and particles from the burning pyrotechnic heat the stored gas causing a rapid pressure rise in the storage chamber.  When the storage chamber pressure exceeds the structural capability of a thin metal disc between the diffuser and storage chambers, it ruptures allowing the heated gas to vent through the diffuser orifices into the air bag assembly.

Title: Ophthalmic lens inspection system and method
Inventor: EDWARDS RUSSELL J
IPC: G02C7/02
Filed: 1993-12-17
Abstract: A lens inspection method and apparatus is disclosed comprising a pallet having wells for receiving one or more lens containers at the receiving point. A conveyor achieves uniformity of pallet motion needed in the direction of pallet travel and stability when transporting the lens in the orthogonal, non-translating directions by use of one or more guide rails and a mechanical bias means. Pallet wells for receiving the containers comprise holes that pass through the pallet. These holes along with a side driven transport system make possible an arrangement of a lamp and camera on opposite sides of the lens for capturing an image of a lens. A computer implemented algorithm processes the digitized image according to rules set forth in a program to determine the acceptability of the lenses. A lens disposition mechanism connected to the computer uses a signal generated by the computer and indicates lens acceptability to disposition the lens by physically separating a container with an acceptable lens from an unacceptable lens. After disposition of containers, the pallet is returned by conveyor to the lens receiving point.
