Patent CA-1281747-C (CA)
Title: Load accumulating system
Inventor: GLADISH HERBERT E
IPC: B65G25/02
Filed: 1987-03-30
Granted: 1991-03-19
Abstract: ABSTRACT     An accumulation and storage system, preferably for palletized loads, utilizes a SAILRAIL  (trade mark) air support system for guiding and supporting an elongated deck during reciprocal movement thereof.  Alongside each edge of the deck is a pallet lifting/lowering mechanism  which uses an elongated inflatable tube, such as a fire hose, to raise or lower an inverted U-shaped lifting member.  When the lifting members are raised a pallet can be placed thereon and the deck can reciprocate therebelow.  When the lifting members are lowered the pallet rests on the deck and can be moved along the system to a subsequent position where it is raised clear of the deck so that the deck can return to pick up another pallet at the input station.  Logic controls can be used to operate the system quickly, efficiently and automatically.

Abstract: COMBINED PHOTOVOLTAIC-THERMOELECTRIC  SOLAR CELL AND SOLAR CELL ARRAY                           ABSTRACT            A solar cell (10) generates an electrical voltage with contributions from both photovoltaic and thermoelectric effects, when a high thermal gradient is impressed across a semiconductor p/n solar cell.  To achieve a substantial thermoelectric voltage contribution, the front side (12) of the solar cell (10) is heated to an elevated temperature consistent with efficient operation of the photovoltaic mechanism of the solar cell, and the back side (14) of the solar cell (10) is cooled to a lower temperature.  The magnitude of the thermoelectric voltage contribution is increased by reducing the coefficient of thermal conductivity of the solar cell material, by using face electrodes (24, 26) having the proper thermoelectric potentials in contact with the solar cell material, by increasing the light intensity and thence the heat input to the front side (12) of the solar cell (10) and by cooling the back side (14) of the solar cell (10).  The preferred material of construction is gallium aresnide, and the solar cell can be mounted to receive concentrated sunlight on its front side and to be cooled on its back side by enhanced thermal radiation.

Title: Optical fibre couplers
Inventor: SHAHIDI-HAMEDANI FERRYDON
IPC: G02B6/28
Filed: 1988-01-13
Granted: 1992-05-26
Abstract: ABSTRACT            Optical fibre couplers are formed by selectively etching the cladding layer of portions of the fibres forming the coupler to provide them with an undulating profile, converging a group of fibres so that the undulating pro-files interlock, and fusing the interlocking portions without drawing the fibres, so as to form a fused coupling zone of blended core and cladding glass.  The fused zone is inserted in a ferrule, or a cladding layer is applied having a numerical aperture selected to maintain a more or less constant numerical aperture through the coupler. Such couplers may be cut in half and the halves optically coupled to each other by applying lenses to the cut ends and inserting the halves from opposite directions into a housing containing refractive index matching fluid so that the focuses of the lenses coincide.

Abstract: Use of optically active 1,3-dioxolane-4-carboxylates as dopes in liquid-crystal mixtures, liquid-crystal mixtures containing these compounds, and novel, optically active 1,3-dioxolane-4-carboxylates.   Optically active, mesogenic 1,3-dioxolane-4-carboxylates are suitable as dopes in liquid-crystal mixtures.  They result in liquid-crystalline ferroelectric phases having short switching times and in electroclinic phases having large electroclinic coefficients.   Their particular advantage is that they induce a helix of very large pitch, meaning that helix compensation by further dopes is unnecessary.  In addition, 1,3- dioxolane-4-carboxylates exhibit high UV stability.  The 1,3- dioxolane-4-carboxylates of the present invention are of the following general Formula (I):

The CO2-laden adsorbent is regenerated by purging with a H2O and CO2-free waste gas stream from the hydrogen purification adsorbent bed or from the cryogenic fractionation or from both of these.

Abstract: The invention provides apparatus for use in a system for surgically implanting an allograft or prosthetic ligament as a replacement for a patient's cruciate ligaments.  In a practice of the system, as a replacement for an anterior cruciate ligament, the patient's leg is bent and maintained at approximately a ninety degree (90°) angle, a single incision is made medial o the tibial tuberosity.  From this incision, under fluoroscopic and arthroscopic control, a guidewire is driven through the tibia and across the cruciate ligament junctions with the proximal tibia and distal femur ends and into the femur cortex.  Successively larger drills are then turned along the guidewire to form a ligament tunnel, with, as a last step in the tunnel formation process, the preparation of the femur cortex end of the tunnel to receive a femoral connector of the implanted ligament, which connector is arranged in one embodiment to be outwardly flared and in another embodiment to be turned into the appropriately prepared femur end of the ligament tunnel to lock therein.  the invention, in addition to the embodiments of the ligament femur end connectors, further includes a tibial surface ligament tibial end connector for both securing the ligament end to the bone and for setting ligament tensioning, of which ligament connectors can be manufactured from a biodegradable material for absorption by the body.

Abstract: PATENT 39.0110.2083 COLOR VIDEO SIGNAL REPRODUCING APPARATUS                  ABSTRACT OF THE DISCLOSURE A video signal reproducing apparatus has a filter circuit interposed in a transmission path for a reproduced luminance signal, and the characteristic of the filter circuit desirably includes a band-eliminating characteristic and a comb-filter passband characteristic which can be selectively emphasized.  When the reproduced luminance signal has a normal or relatively smaller frequency bandwidth or a relatively small line correlation component, or when the level of the reproduced carrier chrominance signal is high, the band-eliminating characteristic of the filter circuit is emphasized.  The foregoing video signal reproducing apparatus is particularly suited for reproducing a color video signal that includes a wide band luminance signal, in which case the comb-filter passband characteristic of the filter circuit is selected or emphasized so as to reduce noise near the color subcarrier frequency, to avoid displacement of a reproduced picture of high definition in the vertical direction and also to avoid interference caused by the vertical non-correlation component of a color picture.

The energy is radiated from an antenna in the form similar to a hypodermic needle which is inserted into the body and into the tumor, the energy being supplied by a microwave genera-tor which can be controlled as to time of operation and power output to the antenna.  A temperature sensor or sensors are also inserted in the body and are located at the outer periphery of the tumor.  The sensors are coupled with a temperature detector and a control unit which controls the operation of the microwave generator to actuate and deactuate it in accordance with the temperature at the outer periphery of the tumor.  The video system is used to assist in placing the antenna and the temperature sensor at the proper location with reference to the tumor within the body.  The present invention is especially suitable for use in destroying cancerous tumors of the breast, brain, skin or other body locations.
