Abstract: ABSTRACT OF THE DISCLOSURE         In a slide fastener having a separable end connection, as of the box-and-pin type, that includes a pin on one stringer tape and a box on the other tape at one end of the fastener, a pair of tape end reinforcements are provided which are molded integral with the pin and the box, respectively.          Each tape end reinforcement has a pair of main portions over-lying the opposite surfaces of one of the stringer tapes and integrally connected together through bridge portions extending through holes in the tape.  The main portions of each reinforcement have convex edges directed toward the other end of the fastener, thus preventing the concentrated formation of wrinkles on the stringer tapes as when the fastener is opened by moving the slider down to the separable end connection.

Abstract: TAPE MOTION CONTROL FOR REEL-TO-REEL DRIVE            Abstract of the Disclosure High tape acceleration rates are achieved in an un-buffered capstanless tape drive system by a tape motion control apparatus employing separate drive motors for each reel of a reel-to-reel tape transport.  Tape moves from one reel past a read/write head and a tape tension sensor to the other reel, there being no tachometer in the tape feed path.  A tachometer on one reel shaft provides a large number of pulses per revolution which pulses are counted by a counter; and a tachometer on the other reel shaft provides only one pulse per revolution, which pulse gates out the count then accumulated in the counter for actuating means to provide motor acceleration currents of a magnitude corresponding to said accumulated count accord-ing to a predetermined servo algorithm for controlling rotation of both reels.  A tape radius constant correspond-ing to the actual length and thickness of tape in the system is calculated during initial wrap of tape onto the takeup reel.  Tension is tightly controlled by an analog tension sensor and servo system.

Abstract: ABSTRACT OF THE DISCLOSURE         A mounting means for fixing a hinge relative to a container wall.  A hinge receiving element is provided with an inner plate having an outer lip joined thereto by an intermediate web.  The container wall is received between and thus reinforced by the aforesaid inner plate and outer lip, with the intermediate web being supported on a wall edge.  Preferably, the inner plate has upstanding ears, the intermediate web is notched at one end, and the container wall has inwardly protruding flange segments at opposite ends of the aforesaid wall edge.  The notch permits both pivotal and lateral movement of the hinge receiving element in order to position the upstanding ears on the inner plate beneath and in contact with the undersides of the flange segments on the wall member.  The inner plate is adapted to receive a hinge leaf in engagement therewith, and the hinge leaf, when thus engaged, prevents reverse lateral movement of the hinge receiving element.

Abstract: ABSTRACT OF THE DISCLOSURE A vent system for an electric storage battery designed to remove the electrolyte which is entrained in the gases that are vented from the particular battery cell to the atmosphere through the vent plug assembly. The liquid gas separation feature has a primary inlet on the sidewall of the vent plug at its uppermost position that still remains in the battery cell, a drain opening in the lowermost portion of the vent plug, and baffles arranged inside the vent plug assembly such that the fluid entering the primary inlet flows in a horizontal direction and is scrubbed to remove the electrolyte.  The electrolyte is then collected and returns to the cell through the drain opening while the scrubbed gases eventually reach the atmosphere. The liquid gas separation system can be used in a vent plug having a low profile for use on maintenance free batteries as well as on non-maintenance free batteries.

Abstract: ABSTRACT OF THE DISCLOSURE         A spiral type one-way clutching mechanism is provided herein which is insensitive to transverse forces; substantially eliminates over-running frictional wear on the critically shaped surfaces of its members; and substantially eliminates the role of chance in establishing the clutching load distribution between its members.  The spiral one-way clutching mechanism is also provided as a spiral type one-way clutch assembly whereby the clutching mode may be active or passive.  The clutch-mechanism utilized a monolithic annular outer body member having an inner spiral surface having at least one spiral segment defining an axially oriented opening through the body member.  A monolithic annular inner body member is concentrically positioned in the axially oriented opening and has an outer spiral surface having at least one spiral segment which is tangentially congruent to the spiral surface of the outer body member, the congruent inner and outer spiral surfaces defining a spiral race there-between.  One end of the spiral race is defined in part by the outer spiral surface having an inner abutment provided by a radially outwardly extending protrusion or flange on the inner body member, the other end of the spiral race defined in part by the inner spiral surface having an outer abutment provided by a radially inwardly directed protrusion on the outer body member.  At least one of the body members has a radially directed expansion slit extending therethrough and at least one limit spring acts between the body members.  The outer body member and the inner body member are relatively rotatably oscillatable with respect to each other.  A plurality of axially oriented, abutting roller members is posi-tioned in the spiral race substantially, but not completely filling, the spiral race, each such member being in contact with the inner and the outer spiral surfaces.  Limit spring means are provided which act between the body members for limiting the relative oscillatory movement there-between.

Abstract: ABSTRACT A vaporized fuel controller for a carburetor which utilizes the negative pressure in the intake manifold and electromagnet to actuate a changeover valve so as to connect the gas chamber of the float chamber to the inner vent when the engine is running, and to the canister when the engine is not running.   With this invention, when the negative pressure in the intake manifold decreases while the engine is running at high speeds, the electromagnet keeps the valve from being moved by the spring force and maintains the valve at a position such that the vapor fuel is supplied to the intake manifold through the inner vent.
