Abstract: BRAKE BOOSTER                       ABSTRACT OF THE DISCLOSURE A brake booster includes a housing with an inner wall defining a pair of pressure chambers.  A passage in the inner wall communicates the pressure chambers with each other and an input member is slidably disposed in one of the pressure chambers and an output member is slidably disposed in the other pressure chamber.  A resilient member extends between the inner wall and the input member and substantially defines a variable orifice to control fluid communication between an inlet and a return.  The return is disposed within the inner wall and the resilient member comprises a coil spring which permits fluid communication between the coils.  When the input member is moved the coil spring is contracted to decrease the spacing between the coils, thereby restricting fluid communication between the inlet and the return.  Consequently, increased fluid pressure within the other chamber urges the output member to move thereby actuating braking.   In addition, a push member carried by the inner wall provides for transmission of movement from the input member to the output member directly.

Abstract: ABSTRACT OF THE DISCLOSURE     A dispenser for a roll of strip comprising an open top casing.  A cover is pivotally mounted on the casing for closing the top thereof.  Disposed within the casing is a roll of strip having transverse slits formed therein at predetermined distances along the strip.  The free end of the strip to be removed from the roll of strip exits from an opening located between the casing and the cover.  Extending from the casing are transversely spaced tracks that project outwardly and downwardly from the casing, and over which advances the free end of the roll of strip.  Extending from the cover are outwardly and downwardly transversely spaced guides, which overlie, respectively, the transverse tracks to form passages therebetween.  The free end of the strip travels through these passages.  The tracks and guides are correspondingly curved to bow the free end of the roll of strip at the transverse slit advancing through the passages to open the slit.  A spring mounted on the casing applies a restraining force to the roll of tape.  An operator grips the free end of the roll of strip disposed between the transversely spaced tracks and guides and applies a downward force to the free end of the roll of strip.  The free end of the roll of strip is torn from the roll of strip at the transverse slit exiting from the passages by virtue of the restraining force applied to the roll of strip, the force applied to the free end of the roll of strip by the operator, and the frangibility of the free end of the roll of strip at the opened slit.

Abstract: ABSTRACT OF THE DISCLOSURE            An interlock switch comprises a standard snap action switch, provided with an actuating leaf, coiled at one end and fixed to the switch housing at the other end. In one application the switch is to be actuated by a door latch handle which passes between an open and a closed position by engaging the coiled actuating leaf. The leaf is initially oiled such that the coil is engaged by the latch handle early in its travel.          When the latch handle is closed for the first time, the coil is unrolled to a closed coil position at the closed position of the latch handle. When the latch handle returns to the open position, the coil re-rolls only slightly to a new open coil position displaced a short distance from the closed coil position.          The coil is thus positioned so that in subsequent latch handle closings, the coil is not engaged until the latch handle approaches the closed position.

Abstract: ABSTRACT OF THE DISCLOSURE           A button cell package in which button cells are releasably retained in position by an adhesive surface layer on a laminated structure having a resilient layer between the adhesive layer and a nonresilient base.  An additional layer having preferential barrier properties is used with cells of the metal-air type and is located between the adhesive surface layer and the resilient member.  The adhesive layer seals the metal-air cell to increase cell shelf life and prevents inadvertent dislodgment and loss of cell capacity, yet permits small amounts of evolved hydrogen to diffuse from the cell.          The resilient layer serves as a cushion and provides a means for obtaining maximum surface contact between the adhesive surface layer and the button cell surface to maintain the cell in impact-resistant, releasable adhesive contact with the adhesive layer.          The method of assembling the package is also described.

Abstract: ABSTRACT OF THE DISCLOSURE       An electrical display device, such as a liquid crystal display, for an instrument such as a speedometer, where two or more units of measurement may be required, comprises a first display area which extends along a line and which is formed to indicate a point along the line corresponding to the magnitude of a measured or selected value; a second display area adjacent the line adapted to indicate a length along the line upon which the point may be indicated; and two further display areas which are formed to be activated separately from the first and second display areas and from each other, and adapted to indicate a respective scale of markings against which the magnitude of the said value can be read, and said further display areas lying on the opposite side of the second display area from the first display area, and one of the further display areas including a part which forms an extension of the length of the line indicated by the second display area.  By effectively increasing the length of the base line when the said one scale display area is activated, the indicia on the said one scale display area can be positioned between the indicia on the other scale display area, thus avoiding overlap of their electrodes  and allowing the leads to the electrodes of both scale display areas to be positioned away from the leads to the electrodes for the first and second display areas.

Abstract: WEATHERSTRIP AND METHOD FOR SEALING A GAP      ABSTRACT         There is provided a weatherstrip for sealing a gap between members that are movable relative to one another between non-aligned and aligned positions.  The weatherstrip includes a backing strip, preferably of fabric material, that can be secured to one of the members.  One or more sealing bodies, such as rows of pile fibers, extend longitudinally with respect to the backing strip.  The sealing bodies are secured to the backing strip and cooperate therewith to form a sealing assembly.  Each sealing body has a free surface portion remote from the place of attachment of the sealing body to the backing strip.  A flexible film is secured to the sealing assembly and extends longitudinally of the backing strip.  The flexible film has a free edge portion opposite to the part thereof which is secured to the sealing assembly.  This free edge portion extends beyond the free surface portion of each sealing body for a substantial distance so that the free edge portion of the film can be bent over at least a part of the free surface portion of the sealing body.

Abstract: RCA 74,396 ABSTRACT             A first resistive current path is DC connected between respective output terminals of push-pull color demodulator.  A second resistive current path is DC connected between respective output terminals of a second push-pull color demodulator.  An output color-difference signal is formed by a differential amplifier having one input DC connected to an asymmetrically positioned point in first resistive current path, and a second input DC connected to an asymmetrically positioned point in second resistive current path.  Output color-difference signal corresponds to a combination of the demodulated signals, with a polarity relationship and magnitude ratio determined by the asymmetry of positioning of the takeoff points in the respective current paths.  Output quiescent voltage is independent of the asymmetry of positioning of the D takeoff points.
