Patent DE-2167015-A1 (DE)
Title: Regular rectangular plastic foam blocks - continuous prodn
IPC: B29C44/46
Filed: 1971-05-11
Abstract: Continuous rectangular block of plastic foam are produced by a free foaming process in which the plastic mixture is fed on to a laterally enclosed conveyor belt and its movement and expansion aided and controlled. The surfaces of the two enclosing sides and of the conveyor belt are covered by moving foils unwinding from rolls, whilst the plastic material itself may be covered by a gas-permeable sheet and a further covering to impede the escape of fluids, both of which wind off from assemblies supported over the foaming area. On the covers there is a levelling device comprising a roller and heavy metal grill. This mechanism is supported in a conveyor and is adjustable horizontally and vertically.

Title: Shuttleless loom weft - with measuring and storing facility
Inventor: JANKOVSKY JOSEF DIPL ING
IPC: D03D47/36
Filed: 1972-05-08
Abstract: Device delivering a measured length of weft yarn to the weft inserter of a shuttleless loom, measuring the length of the pick quicker than it wound on the storage drum, the unwound part forming a free loop between two guide plates. A storage drum integral with a belt pulley which drives it rotates co-axially with a cam plate. A two-armed lever which swings on a pin in the web of the storage drum has a bill at one end and a roller at the other, running in the groove of the cam plate. Through an adjustable belt pulley the storage drum is linked to a measuring drum with a pressure roller which draws the yarn from the supply package. The yarn delivered by the measuring drum loops up between the guide plates and through an adjustable braking mechanism down to the spiral grooves of the storage drum around which it is wound as the bill of the swinging lever grips it. The timing of the cam plate then swings the bill below the circumference of the storage drum, and the weft inserter puts the yarn in the shed.

Title: Cine film projector cassette with coaxial film chambers - has a partition between the spools and film control springs
Inventor: HOEPFNER CLEMENS
IPC: G03B21/32
Filed: 1973-09-04
Abstract: The cassette is designed for simple and economical mass production and for uncomplicated and reliable performance. The cassette has a main body and two covers. The two coaxially arranged spools are separated by a partition. The film leaving the supply spool passes over a leaf spring tensioner. The take-up spool acts in conjunction with a film guide and brake. This consists of a spring loaded pivoted element whose free end bears against the film coil on the spool. The tensioner and brake prevent loosening of the film winds when the cassette is removed from the projector. This ensures smooth film transport and enhances performance particularly with synchronised sound.

Title: Rotary internal combustion engine ignition system - fires one or two plugs per cylinder according to engine speed
Inventor: BENSINGER WOLF-DIETER DIPL ING
IPC: F02B53/12
Filed: 1973-11-28

Title: Lever linkage driving ram of cutters or form presses - in which ram and hinge point are connected to the far points
Inventor: NOCKHER GERHARD DIPL ING
IPC: B30B1/14

Title: Energy absorbing body structure for motor car - has pp partittiitiiion walls and beams which hh varrry in thickness along their length
Inventor: BEZ ULRICH DIPL ING
IPC: B62D21/15
Filed: 1974-05-02
Abstract: The wall thickness of the beam (9) running from the passenger compartment (5) to the end wall (7) of the vehicle is less in the region (D) near the end of the vehicle than in the region (E) near the passenger. The beam can have a rectangular or more circular cross-section and is welded, riveted or stuck to the passenger compartment.

Title: Top most tissue dispenser - first tissue is automatically separated from continuous length of single leaves
Inventor: GERSTEIN DAVID E
IPC: A47K10/34
Filed: 1974-08-01
Abstract: The dispenser contains a continuous length of individual tissues, connected at the front ends via tear-lines. It has a container with a housing for the tissues, and a closure. A unit forms a dispensing aperture, and the individual tissues are automatically separated, from the length, when passing through it. The unit consists of a slot and an associated elastic flap. When a tissue is pulled through the slot, the flap applies a friction force onto the length, which is larger than the force, necessary to separate neighbouring tissues. The dispensing aperture is covered by an easily removeable lid, hinged to the container. The flap is formed as an integral part of the closure. The closure has a raised part, surrounded by a sealing lip, and containing the slot.

Title: Double piston pneumatic vacuum valve - has lower electro-magnetic valve for rapid closing upon power failure
Inventor: KAISER KARL HEINRICH
IPC: F16K31/122
Filed: 1974-08-10
Abstract: The double piston actuator has a piston working in a cylinder connected through an orifice to the direct outlet of an electro-magnetic valve. The lower cylinder is connected to the control pressure outlet of the electro-magnetic valve. As long as the pressure supply to the upper cylinder is maintained, the piston presses against the top cover which lifts the bottom plate through bolts, and allows a spring to hold the main vacuum valve open. If pressure is supplied to the lower cylinder the piston is pushed downwards against a bush and valve plunger overcoming the force of the spring and closing the valve.
