Patent DE-1810844-A1 (DE)
Title: Flexible foams for use as tennis courts golf courses
Inventor: ANDERSON BLACKBURN WILLIAM
IPC: C08J9/30
Filed: 1968-11-25
Abstract: Flexible foams based on a plasticised copolymer of a vinyl halide and a vinyl comonomer and having a coefficient of restitution of less than 0.33 (the coefficient is given by V2 sinbeta/V1 sinalpha where V1 is the impinging speed of an object, alpha is the impinging angle, V2 is the parting speed and beta is the parting angle). The foam have a high compressibility, a low resilience, a fast recovery to the initial form, good resistance to weathering, high tensile strength, good dimensional stability, and excellent performance over a wide temperature range. The kinetic energy of impinging objects is dissipated rather than converted into an elastic response. Uses are for tennis courts, golf courses etc, where the response to the ball is similar to that obtained on grass.

Title: Stepless locking unit for embow joint of arm prosthesis - has clamp bodies locking axle w.r.t. rotary ring
Inventor: PRAHL JAN
IPC: A61F2/58
Filed: 1973-10-04
Abstract: Stepless locking unit, acting in both directions, is for arm prostheses and ortheses. Clamp bodies are fitted to an axle disc such that they can prevent rotary motions between a rotary ring and the disc. The locking action of the clamp bodies is lost under the effect of a unit, releasing the rotary ring and the disc. More partic., the system is simple and can steplessly lock both the rotation directions of the elbow joint; the force path for locking the system is kept very short. Apertures in the axle disc receive the clamp bodies, which are brought into working position, e.g. by a lever system, the pressure on which can be exerted via an elastic element from the disc.

Title: Gas or steam pipe safety equipment - comprises enclosing strip clear of pipe and mounted in adjacent wall
Inventor: HOFFMANN JUERGEN
IPC: G21D1/02
Filed: 1974-06-21
Abstract: The equipment protects the environment in the event of pipe breakage, incorporating a retaining strip enclosing the pipe and fixed to the adjacent vall (3). The strip (4) passes round the pipe (1), which is suspended so as to allow movement due to heat expansion at a distance far enough from it for no contact between them to occur under any operating conditions. The strip stiffness is such that it does not distort beyond the leastic limit as the result of inherent loads (due to its own weight, vibration or temperature). Any bending loads in excess of them result in alteration of the strip position. The strip can be of flat iron, with stiffening sheet-metal ribs extending outwards normal to it and welded to it for part of the way along (6).
