  • Patent number: 4048822
    Abstract: A door lock, requiring no penetration of a door leaf for unlocking from the outside, comprises a keeper secured to the inner surface of the door leaf, a housing slidably articulated to the keeper by two pivot studs, and a detent on an adjoining door post engageable by a pair of spring-loaded levers in the housing whose fulcra are a pair of pins normally immobilized by a retaining disk. With the door closed and the detent engaged, the housing fits around the keeper and can move away from it to a limited extent, allowing the door to be opened slightly, unless a handle on the housing is turned into a latching position engaging a bolt fixed to the keeper. Unlatching of the door from within, by reverse rotation of the handle, also disengages the levers from the detent so that the door can be opened wide. When the door is opened from the outside, its leaf is held ajar by the housing whose handle cannot be rotated in this position since the levers are blocked by the pivot studs.

  • Patent number: 4037947
    Abstract: A cine camera for taking talking pictures, in which a film is moved intermittently past an image gate by a reciprocating traction claw and continuously past a recording head by a rotating capstan coacting with a pinch roller, includes a latch by which the pinch roller can be held spaced from the capstan in an inactive position. The latching of the pinch roller in this inactive position, against the force of a biasing spring providing the necessary contact pressure during filming, is accomplished upon deactivation of the film drive by the residual kinetic energy of an inertial mass such as a flywheel which is coupled with either the capstan drive or the claw drive. The latch is released upon actuation of a trigger, either directly or through the intermediary of the claw drive. The biasing spring may be part of a toggle mechanism tripped by a presetting member, such as a sensor detecting the presence of a sound-film cassette in the camera.

  • Patent number: 4036034
    Abstract: Disclosed is a method and apparatus for knitting patterns with a circular knitting machine provided with an annular array of knitting needles and groups of needle actuators. Pattern signals in binary notation are read out of a memory device and written into first one and then the other of a pair of counter stages. While pattern signals for a given course of knitting are being read out from one counter stage and forwarded to the corresponding actuators, pattern signals for the next course of knitting are written into the other counter stage from the memory device. The pattern signals alternately read out from first one and then the other counter stage are forwarded to the corresponding actuators by means of selection circuits to thereby produce a knit fabric having a continuous colored pattern.

  • Patent number: 4027520
    Abstract: A blind riveter has a pistol-shaped housing connected via hydraulic and pneumatic lines and a rivet-feed duct to an actuator and rivet-feed arrangement. The housing has a tip forming a mandrel-receiving aperture and formed of a plurality of inwardly biased but outwardly deflectable holding elements. A chuck is displaceable in this housing between a front position engageable around the mandrel extending back through the aperture from a blind rivet whose head rests against the tip and a back position spaced well back from this aperture. During displacement from the front to the back position the mandrel is pulled back to upset its rivet and is broken off and during displacement from the back to the front position, the chuck grips the mandrel of a blind rivet that was introduced from behind into the housing behind the aperture and pushes it through the aperture, deflecting the holding elements apart.
