Patent CA-2186308-A1 (CA)
Inventor: MUHS DONALD P
IPC: F16K31/124
Filed: 1996-09-24
Abstract: A new technique is described for the design of a valve which is to be employed in systems which incorporate gas flow control management. The valve of the present invention has a valve assembly and a control element which provides control of the valve cycle rate of the valve assembly. Varying a control signal of the control element causes a pressure differential across a selected piston of the valve assembly and causes a poppet of the valve assembly to disconnected from the selected piston and connect to a new piston. In this way, the valve cycle rate of the valve assembly is controlled. The valve of the present invention described offers improvements over prior art valves in the areas of product economy and valve cycle rate control. An improvement in economy is effected because the described invention does not require a gear motor for operation, which reduces cost. A controllable, variable linear valve cycle rate is achieved which is not restricted by the RPM characteristics of a gear motor.

Title: Flexible sheet or tape for use in a method for repairing pipelines, or the like
Inventor: FRIEDRICH JAROMIR
IPC: F16L55/168
Filed: 1996-10-10
Abstract: A tape or flexible sheet is described for use in repairing ruptured pipelines orthe like. The flexible sheet or strip is comprised of a plurality of longitudinally arranged fibers of a generally identical cross-section. The fibers are disposed in a side-by-side arrangement within a thermoplastic or thermosetting matrix. The thickness of the sheet or strip is generally equal to the diameter of the fibers which is usually in the range of from about .006 to about .010, whereby side portions of the fibers are encased in said matrix, but the portions at opposed faces of the sheet or strip are generally exposed.   This assures that the fibres or wires or the tape, when applied, engage directlythe surface of the workpiece or the wires or fibres of the adjacent layer as opposed to prior art where a plastic intermediate layer was deliberately maintained giving rise to the danger of leaks or blowouts.

Patent CA-2205820-A1 (CA)
Title: Optic position sensor
Inventor: DRENTH RONALD R
IPC: G01S17/87
Filed: 1997-05-22
Abstract: The present invention involves an apparatus and a method for optically detecting and determining the angular position of a target.  The apparatus comprises a pair of optic sensors arranged so that at least a portion of their sensing areas overlap.  Their overlapping areas define the total sensing, or active sensing, area for the apparatus.  Each of the optic sensors in the apparatus senses light, or other optically sensible transmission, either projected or reflected from a target positioned within the total sensing area and produces a signal relative to the amount of light sensed.  The signals are then interpreted to determine the angular position of the target based on the relative signals from the optic sensors.  The method of the present invention determines the angular position of a target within an area, defined by the overlapping sensing areas of a pair of optic sensors, by interpreting the relative signal intensities from the pair of optic sensors.  Once the angular position is determined, the distance of the target from a line either perpendicular to or parallel to the center line of the sensor array can be calculated if the other quantity is known.

Abstract: A process and device for pressure-controlled manipulation of a fluid (4a), in particular for medicinal applications. The device comprises a receptacle (1a) of variable volume to contain the fluid (4a), a pressure creation device (2a) for producing pressure on the fluid (4a), an opening (1c) for admitting and/or discharging the fluid (4a), a measuring channel (2e) of prescribed crosssection connected to the receptacle (1a), and a buffer (2d) of prescribed volume which communicates with the measuring channel (2e), the measuring channel (2e) and the buffer (2d) being filled with a compressible medium. The pressure creation device is preferably a piston (2a) which can be pushed into the receptacle (1a), the piston being sealed to the inner wall of the receptacle (1a) by a sealing means (2c). According to the invention, in particular medicinal syringes are improved in that a fluid (4a) can be injected with particular evenness and at a pressure which can be precisely controlled, for example into a cavity (10) a body (9). The presssure is read or measured by determining the position of the boundary layer (8) between the fluid (4a) and the compressible medium in the measuring channel (2e), e.g. by means of a scale (2k). The size of the buffer (2d) in relation to the internal diameter of the measuring channel (2e) determines the precision of measurement and the damping properties at the time of injection.

Abstract: According to a first embodiment,  an apparatus  for shielding a movable articulated structure such as robot arm  to  be  protected  from  a  hard working  environment comprises one or more shielding sections forming with the outer surface of the robot arm a cavity which is filled with pressurized air. Adjacent portions of the shielding sections  are  coupled  through  a  rotary  joint  allowing escape of the pressurized air out of the cavity while maintaining  within  the  cavity  a  positive  pressure relative to the ambient environment pressure which  is sufficient to substantially prevent contamination of the robot arm from the working environment. According to a second embodiment,  the apparatus comprises  a shielding cover comprised of one or more cover sections  forming with the outer surface of the robot arm a cavity which is filled with pressurized air.  A   positive gas pressure relative to environment ambient pressure  is maintained which    is    sufficient    to    substantially   prevent contamination  of  the  robot  arm  from  the  working environment. The cover section is essentially made of a substantially gastight and impermeable flexible material which is sufficiently stiff to provide the cover section with sufficiently smooth and stiff outer surface under the positive pressure, to substantially prevent physical contact between the robot arm outer surface and the cover section which could otherwise result in cover chafing.
