Patent CA-1057971-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention is a differential pressure measuring cell which includes first and second input pressure chambers, diaphragms mounted therein, an auxilliary chamber having a relatively flexible diaphragm, and a measuring chamber having a relatively rigid diaphragm.  Capacitor sensing foils line the opposite concave walls of the measuring chamber.  A first input pressure P1 is communicated, via a first pressure chamber diaphragm to one side of the auxiliary chamber, and via first passages and a first cylindrical recess, to one side of the measuring chamber.          Similarly, a second input pressure P2 is communicated, via a second pressure chamber diaphragm, to the other side of the mea-suring chamber, and via second passages and a second cylindrical recess to the other side of the auxiliary chamber.         Radial expansion of the auxiliary and measuring chambers and  consequent measuring errors due to the resultant diaphragm tensionings, are prevented by the static counterpressures pre-sent in the recesses.  Overpressure protection is provided by the small volumes behind the pressure chamber diaphragms and the greater flexibility of the auxiliary diaphragm, whereby the pres-ure chamber diaphragms seat against their adjacent casings and the flexible diaphragm absorbs any excess pressure before the rigid diaphragm engages its chamber walls and becomes deformed thereby.

Abstract: ABSTRACT           A cartridge for an endless band printer ribbon includes a chamber for storing the ribbon in a convolute therewithin.  One or more segments of the ribbon are main-tained exteriorly of the cartridge to overlie and close the open end of a corresponding depression(s) formed in the cartridge's periphery to form a protrudent member-receiving compartment.  The number of depressions corresponds to the num-ber of protrudent ribbon guides (rollers, posts, etc.) in the printer.  The protrudent member-receiving compartments are positionable so that their corresponding guides may be simultaneously received therein.  After such reception, the cartridge is moved away from the guides, which there-upon engage and withdraw the ribbon from the convolute by unwinding it until the cartridge is mounted to the printer and a portion thereof is properly adjacent a printing loca-tion on a platen.  The cartridge may also contain a one-way clutch to effect unidirectional ribbon movement and a ribbon re-inker.

Abstract: PHB 32,541 ABSTRACT            A radio interferometer system for determining the angle of incidence of signals received from a remote radio source comprises a substantially linear series of n + 1 (n ? 2) aerial elements.  The two outermost aerial elements form a first pair to which a digital phase discrimator is coupled to measure accurately but ambiguously a first phase difference between sig-nals received by this first pair.  Digital logic means are used to resolve the ambiguity of this first phase difference measure-ment to produce an accurate and unambiguous measurement with means connected to the digital logic means to produce an in-dication of the angle to be determined.  Each two successive aerial elements form successive further pairs to which further digital phase discriminators are coupled to measure unambiguously further phase differences between the signal received by these further pairs.  Digital logic means are arranged to add these unambiguously measured further phase differences to produce a sum and to compare this sum with the ambiguous first phase dif-ference measurement to produce the accurate and unambiguous measurement.

Abstract: METHOD FOR MAKING CLAD METAL SHEETS HAVING AT LEAST   ONE CURVED MAJOR SURFACE AND PRODUCTS THEREBY          ABSTRACT OF THE DISCLOSURE  A base metal having at least one curved major surface is placed on a hard plate in such a way that the curved surface is in opposed relationship with the hard plate, and a cladding metal sheet is placed in opposed and spaced-apart relationship with the upper flat major surface of the base metal.  The cladding metal sheet is firmly bonded to the base metal by explosive welding, and the curved surface of the cladding metal bonded becomes substantially in conformity with the curved surface of the base metal prior to the explosive welding. A clad metal sheet with a higher degree of dimensional accuracy may be provided and the bond is very strong and highly reliable.  With copper base metal and composite cladding metal sheets each prepared by butt-welding foreign metal sheets which may be different in thickness, a mold for continuous casting may be produced which may substantially eliminate casting defects.

Abstract: ABSTRACT       A stamp dispensing mechanism has a cylindrical feed wheel, with axially-parallel rows of projections, rotatably mounted on a front portion of a vertical support plate that is constructed to rotatably support  a roll of stamps on its rear portion.  A Geneva star wheel, rotatably mounted on the plate, is operatively connected to the feed wheel for its step movement with the star wheel.  A Geneva drive assembly, rotatably mounted on the plate, has a driver pin on an arm rotated by a motor also mounted on the plate,  During one rotation of the arm, the pin moves into and out of slot of the star wheel for its step movement.  An arcuate part of the arm is in a recess in the peri-phery of a tooth of the star wheel, when the pin is not in the slot, to lock that wheel.  The rear portion of the top and bottom walls of a horizontal opening of an enclosure, mounted on the plate forwardly of the feed wheel, provides a rearwardly facing surface, with arcuate grooves in which the forward chordal section of the feed wheel extends with its projections in the grooves. An arcuate guide with arcuate grooves is pivotally mounted at one end on the plate and lockable at the other end to overlie the feed wheel with its projections in those grooves.

Abstract: Abstract of the Disclosure The invention disclosed is primarily concerned with reducing the effect of spurious vertical deviations in the groove of a phonograph disc which result principally from record warp.  Such imperfections can cause significant degradation of the reproduced signal.  The playback apparatus of the invention comprises a turntable and cartridge and a sensor which senses vertical deviations of a disc on the turntable.  The sensor controls the operation of an actuator which moves the disc in a direction to eliminate vertical deviation of the disc at the cartridge.  According to a preferred arrangement the sensor senses vertical deviation of the disc in close proximity to the cartridge and with respect to a vertically fixed reference.

Abstract: AN INTRAVENOUS TUBING CLAMPING DEVICE            ABSTRACT   An intravenous tubing clamping device for control-ling fluid flow through compressible tubing.  The device includes an elongated member having a proximal end and a distal end and being adapted to receive the tubing.  The body member has a generally V-shaped longitudinally-extending groove having an angle of about 60° to 165° defining two supporting surfaces for the tubing.  A roller is mounted on the body member for movement longitudinally of the body member to define a clamping area between the roller and the supporting surfaces of the body member which decreases as the roller moves from the proximal end towards the distal end of the body member.  Preferably, the clamping area has a general V-shape and an area that varies between a value equal to or greater than the cross-sectional area of the unclamped tubing and a value approxi-mately equal to the area occupied by the collapsed tubing which is approximately equal to twice the nominal wall thickness of the tubing.  Also, the roller has a generally V-shaped circumference having an apex angle centrally located on the roller having a value of about 60° to 180°.          The size of the clamping area is varied by moving the roller towards the supporting surfaces, by moving the bottom of the V-shaped groove in the body member towards the roller,  or by a combination of moving the roller towards the V-shaped groove and moving the base of the V-shaped groove towards the roller.
