Abstract: An angle joint, consisting of a ball socket and a ball pivot, is pivotally mounted, by means of the ball, in a ball socket recess which is shaped like a spherical cap and acts as a ball seat. On one side of the ball socket is a rigid locating or contact shoulder, which is integral with the ball socket and partially grips the rear of the ball when the ball has been inserted into the recess.A locking element, which is situated opposite the locating shoulder, also partially grips the rear of the ball when the ball is inserted into the recess. The locking element is slidably located in a guide recess in the ball socket at an acute angle, between 15.degree. to 30.degree., to the direction of insertion. A locking spring presses the locking element in a direction opposite to the direction of insertion. The locking element is loaded by a pretensioned helical spring, acting as a locking spring, which bears both against the locking element and a section in contact with the ball socket.

Abstract: A sprocket drive mechanism for transporting film through a motion picture camera includes a frame and a sprocket wheel rotatably supported on the frame and adapted to engage the film. A drive plate is rotatably supported on the frame which is rotated by a drive mechanism. A knob is coupled to the sprocket wheel for rotation therewith. A coupling plate is rotatably supported on the frame and is axially coupled to the knob for selectively rotating the knob. The knob, where manually actuated, axially displaces the coupling plate between a first position where the coupling plate is engaged with the drive plate for rotation therewith and a second position where the coupling plate is disengaged from the drive plate. The coupling plate, when in the first position, rotates the knob which in turn rotates the sprocket wheel. The knob, when the coupling plate is in the second position, is manually rotatable to permit manual rotation of the sprocket wheel to adjust the film.

A first end of an elongated, light-weight film feeding pin is pivotally coupled to a first crank. The film feeding pin includes an advancing taper at the second end thereof for engaging with and advancing the film. A second crank includes a guide for guiding the film feeding pin. The first and second cranks are mutually eccentrically driven so that the film feeder pin reciprocates with respect to the guide, while the film feeder pin and the guide synchronously pivot so that the advancing taper on the film feeder pin defines an elliptical path thereby intermittently engaging with and advancing the film for exposure.

Abstract: A lengthwise adjustable gas spring consists of a housing containing gas under pressure, which is formed by an outer tube 2 and a coaxially disposed inner tube 3 with an annular channel 4 therebetween. A closed piston 5 sealed against the inner tube and axially movable within same, is connected to a piston rod 9, which extends through a seal formed by a plug 10 at one end of the housing. A valve 23 is disposed at the other end of the housing and is used for the regulated connection via the annular channel 4 of two partial housing chambers 20a and 20b disposed on either side of the piston within the inner area of the housing. A valve lifter 22 is embodied within the valve body and is sealed against the valve body and opens or closes gas transfer ports. The valve body 23 and the plug 10 are axially supported against the inner tube 3 and are sealed against the inner surface of the outer tube 2. In order to avoid use of separate seals, the valve body e.g.

Each of the spring strut assemblies is double-acting, i.e., it has an upper guide rod and a lower guide rod, each of which is surrounded by a compression spring. The top of the upper guide rod is attached to the washing machine housing and the bottom of the lower guide rod is attached to the base of the machine. The free ends of the guide rods move axially within a single guiding and damping casing which has internal passages for guiding the rods.

Abstract: A position compensation mechanism for maintaining a movie camera in focus upon displacement. An inner housing supporting a film gate is resiliently mounted at a predetermined orientation within an outer housing which supports the photographic optics of the movie camera. A position compensator is coupled intermediate the inner and outer housing for maintaining the inner housing at its predetermined orientation with respect to the outer housing when the outer housing is displaced.

Abstract: A pneumatic spring for use, for example, as a lifting device or support strut for a chair or the like with provision for the adjustment of axial extent. The pneumatic spring is substantially composed of a telescoping cylinder-piston assembly containing a gas and/or fluid under compression. A releasable valve assembly permits the relative position of the piston with respect to the housing to be adjusted arbitrarily. In order to provide for a terminal spring stiffening in the position of near full insertion of the piston rod, the invention provides that a pin extending from the main piston enters a central volume which is thereby sealed off from the remainder of the internal volume. Accordingly, the gas in the remaining available volume is compressed more highly and exerts an increased opposing force on the primary piston during its final insertion.
