Title: Radial piston type hydraulic engine - has flexible joint between shoe and piston with separate ball
Inventor: WINTER KLAUS
IPC: F04B1/04
Filed: 1977-06-10
Abstract: The engine has a rotating cylinder block (2) with radial cylinders (3). A piston (6) reciprocating in each cylinder has a shoe (7) on its outer end which runs on a guide ring (8) on the inside of the engine stator. The ring is eccentric to the cylinder block and thus causes the pistons to reciprocate. Each piston (6) has two projecting lugs (10, 10') in the form of arcs of a circle. A sphere (16) is inserted between them. The shoe has two similar lugs arranged at right angles to those on the piston. It is pushed over the sphere so that its lugs hold it to the sphere. This forms a flexible connection with the ball of the joint separate from both the shoe and the piston.

Title: Small electronic calculator for children - performs arithmetic operations by visibly allowing counter contents to accumulate
Inventor: MEISSL ROBERT ING GRAD
IPC: G06F15/02
Filed: 1978-12-19
Abstract: The calculator has the number upon which simple arithmetic operations are to be performed generated by counting the contents of a counter up or down automatically using a special push-button. This button is depressed until the wanted number is reached. The count speed can be set, using another special push-button. The arithmetic operation to be performed is executed by letting the contents of the counter accumulate automatically using a third push-button. The numbers and the result are displayed. The numbers are generated in a low-frequency pulse generator. This frequency can be increased by the second push-button. The counter uses components of TTL-type. The advantage lies in allowing the child to see that e.g. multiplication is no more than repeated addition. Since there are relatively few push-buttons the display can be large.

Title: Textile-surfaced wall coverings - having warp and weft sheets applied to adhesive-coated backing paper from an auxiliary conveyor
Inventor: MOHR ERNST
IPC: D04H3/04
Filed: 1979-03-15
Abstract: A process for the production of wall coverings with a surface of textile threads whereby a series of transverse (weft) threads are deposited on the surface of a moving drum or conveyor, whence they are transferred to an adhesive-coated backing paper, along with an interior or superior layer of longitudinal (warp) threads. The spacing of the weft threads is controlled by rows of pins along the side of the conveyor, and a suction device beneath it which holds the threads in position. A mechanical pneumatic or electrostatic device transfers the thread sheet to the backing without disruption, where it is overlain by the warp threads, the entire structure being united by adhesive into a simulated fabric-like surface. The procedure produces a fabric-like surface in a simple and rapid manner from the loosely-superimposed sets of threads. the thread sheets can be inspected and corrected or modified before being applied to the adhesive-coated backing, giving a wide range of pattering or texturing possibilities, and obviating the need for a large stock of fabrics.
