Patent FR-2256026-A1 (FR)
Title: Thermoplastics test specimens prodn. by vacuum sintering - and regulated cooling, giving uniform structure
IPC: B29C67/04
Filed: 1973-12-27
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.

Title: Ultrasonic non-destructive testing of materials - has rigid coupling between converter and test piece
IPC: G01N29/30
Filed: 1974-04-10
Abstract: A rigid acoustic coupling is made between an electro-mechanical converter and the test piece by continuous pressure. The converter and the test piece are made to vibrate in common and the material for testing is irradiated with ultrasonic test signals. In the course of the test the rate of change of the test signal amplitude is monitored. When the amplitude drops abruptly, vibration is suspended and the test signal parameters which appear as data carriers for the test case are measured. The parameters of the test signal are measured, not immediately after vibration has ceased, but after an interval long enough to allow the residual stresses on the converter, caused by vibration and pressure, to disappear.
