Patent CA-1309212-C (CA)
Title: Patient support structure
Inventor: GOODWIN VERNON L
IPC: A61G7/043
Filed: 1987-08-12
Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE          An improved patient support structure comprising an articulatable frame, a plurality of elongated inflatable sacks, some of the sacks having one or two comfort slots therein, a low pressure compressed air blower and a plurality of pipes for carrying gas from the blower to the sacks.  A multi-outlet, variable flow, gas valve connects the blower to the pipes and comprises a housing defining an inlet and a passageway. The valve housing further defines at least two cylinder chambers communicating with the passageway and a discrete outlet for each cylinder chamber communicating therewith.  A piston is substantially non-rotatably disposed inside each cylinder chamber and has a threaded opening through the center thereof which receives a threaded portion of a rotatable shaft therethrough.  One end of the shaft is rotated by a motor, and the other end of the shaft is connected to an axle of a potentiometer.  The sacks rest atop a neoprene membrane which covers a planar upper surface of the frame.  Operation of the motor of an exhaust valve is controlled by an electronic exhaust valve control circuit which balances the voltage from the potentiometer of the valve against a voltage output from a preset variable resistor.  A zone valve control circuit similar to the exhaust valve control circuit, has a motor driven integrated circuit and a further integrated circuit which chooses between a plurality of preset step-wise thumbwheel switches based upon a signal from a step-wise linear switch which is mechanically connected to one of the articulatable sections of the frame.  The sacks can be rapidly deflated via a plurality of solenoid valves.  A plurality of pressure sensitive switches indicates when a substantially deflated condition exists in one or more of the sacks.  A plurality of fabric panels is attached via a plurality of snap members to the ends of the sacks and to a portion of the frame.

Treatment of parkinsonism with the controlled release formulation provides several advantages over treatment with the standard carbidopa/levodopa combinations presently employed.
Patent CA-1313232-C (CA)
Title: Twin pulsed arc welding system
Inventor: ZAJACZKOWSKI BOLESLAW
IPC: B23K9/09
Filed: 1988-12-12
Granted: 1993-01-26
Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides a gas-shielded arc welding system using two side-by-side electrodes each of which is provided with current pulses superimposed on a respective background current level to maintain the desired controlled spray transfer mode of the weld metal without overheating effects.  The pulses are supplied to the two arcs out of phase with one another to minimise interaction of their magnetic fields, but this alone is not sufficient to assure stability of the two arcs.  In the system of the invention, one arc is designated as the master arc and the other as the slave arc. The master arc is stabilized by means of a feedback loop controlling its master pulse frequency.  Each master pulse triggers a respective slave pulse after a preset time delay, in this way keeping corresponding master and slave pulses in synchronism.  This is not necessarily sufficient to stabilise the slave arc and independent stabilisation is therefore provided for it by a feedback loop controlling its pulse duration or its background current, but preferably by controlling both simultaneously.

Title: Non-alcoholic mouthwash
Inventor: COLE B HARRISON
IPC: A61K9/16
Filed: 1989-03-08
Granted: 1994-04-26
Abstract: ABSTRACT OF THE DISCLOSURE    A non-alcoholic effervescent compound for cleaning and  disinfecting  the  mouth,  teeth,  gums  and  breath without necessity of alcohol as a solvent.   Surface acting  agents,  or  surfactants,  are  used  to  reduce surface   tension   of   the   compound   in   solution, facilitating  dissolution  of  all  additives  including non-soluble oil-containing components.   Surface acting agents  also produce  a  foaming  effect which  loosens bacteria and food off and out from between teeth.  The compound eliminates use of alcohol as a solvent, has increased  cleaning  action  from  both  foaming  and effervescence  and produces  a good-tasting,  desirable mouthwash with appropriate flavor concentrations.

Title: Modular flat-screen television displays and modules and circuit drives therefor
Inventor: BRODY THOMAS PETER
IPC: G02F1/1333
Filed: 1989-07-17
Granted: 1992-07-28
Abstract: ABSTRACT      A modular flat-screen  television display  having  a large  area image can be made using an array of modules of easily manufacturable size and preferably removable.   The image  on each module extends to the edge of the module so that when placed in the  array  there  is  no  substantial interruption  in  the  television image since the distance between modules  is  the  same  as  the  distance  between picture  elements  within the modules.  Control and drive circuitry enable each module to  be  driven  at  the  same time,  thereby decreasing the time it takes to refresh the entire display.   The  modules  contain  picture  elements which may be emissive, reflective or transmissive.

Abstract: SEMICONDUCTIVE METAL SILICIDE RADIATION DETECTORS       AND SOURCE                       ABSTRACT Semiconducting metal  silicide electromagnetic radiation  detectors  have  a  thin  film  of semiconducting  metal  silicide,  such  as  rhenium disilicide, grown or deposited on a silicon wafer. The detectors are intrinsic semiconductor detectors and can be formed either as discrete devices,  or monolithically  on  a  silicon  chip  to  provide  an integrated  detector  or  detector  array.    The semiconducting  rhenium  disilicide  detectors  are efficient  at  wavelengths  which  mate  with  the transmission capabilities of certain optical fibers, thereby enhancing the   combination   of   infrared detectors and optical fiber transmission previously known. The  range of electromagnetic radiation sensed by these rhenium disilicide detectors include the infrared range of wavelengths up to 14 microns.
