Patent DE-2359112-A1 (DE)
Title: Thermoplastics test specimens prodn. by vacuum sintering - and regulated cooling, giving uniform structure
Inventor: ZILVAR VACLAV
IPC: B29C67/04
Filed: 1973-11-27
Abstract: Thermoplastic polymer test specimens are produced by sintering the polymer in a mould in an evacuated oven under reduced pressure at a temp. at which viscous flow of the polymer takes place, i.e., at a temp. at which the polymer is sufficiently liq. and no forces act on the polymer which produce undesirable orientation of the macromol. For a crystalline polymer, the required orientation of the crystalline phase is produced by cooling the polymer to the crystallisation temp. or supercooling under controlled conditions, pref. by cooling to the ambient temp. at a certain rate under vacuum or atmos. pressure; or by supercooling to the crystallisation temp., which is below the m. pt. of the polymer, and crystallising freely under isothermal conditions. Specimens of uniform structure can be made, which are more suitable for accurate determination of the physical, mechanical and other props. of the polymer than those made by other methods, e.g., injection, extrusion or compression moulding.

Patent DE-2409684-A1 (DE)
Title: Hydrostatic drive with reversing valve - has valve to drive pump displacement actuator and operate reversing valve
Inventor: NEMBACH SIEGFRIED
IPC: F16H61/46
Filed: 1974-02-28
Abstract: A hydrostatic drive consists of a variable displacement pump, driven by a prime mover, supplying a variable displacement motor. An auxiliary pump supplies fluid to a directional control valve coupled to a servo-cylinder varying the pump displacement. Actuation of the directional control valve to supply fluid to move the servo-cylinder left generates high pressure flow from the pump. At the same time the control valve output differential causes a switch over valve to move right. This transmits high pressure fluid through a line to a line coupled to an actuator controlling motor displacement. The motor displacement is modified to resist the increased pressure from the pump. The arrangement reduces the effects of sudden changes in pump displacement.
