Patent FR-2508501-A1 (FR)
Title: Determination of weft length-on shuttleless loom, - using weft detector and weft brake
Inventor: DEBORDE ALBERT HENRI
IPC: D03D47/34
Filed: 1981-06-30
Abstract: Determination of pick length for insertion into a shuttleless loom is effected not by measurement but by an appropriate pick-up detecting the arrival of weft yarn on the side opposite to the insertion nozzle. Measurement and storage of the yarn are no longer required, but the weft brake is retained, which is controlled by the detector when the arrival of the weft at the side opposite to the nozzle shows that sufficient weft has been transferred. The errors in measurement due to speed change of the loom are avoided, and by elimination of the normal measuring device, the use of the fluid jet loom may be extended to multi-colour weaving.

Title: Measuring system for processor control of actuator - uses force gauge to drive length gauge to transmit force data to processor
IPC: G01B3/00
Filed: 1981-12-28
Abstract: A force gauge is subjected to action from a jack to apply a force to a regulator. The force gauge drives a length gauge which transmits instantaneously the force applied at the gauge to a control system to provide error correction. The control system executes calculations for mathematical equations and is able to use the resultant data or to store it in a memory. As the applied force decreases the length gauge follows the return movement of a control lever. A probe in contact with the lever is moved to reduce the operating gap to zero. This gap information is included as a constant in the control equations which are applied by the control system to control a cylindrical adjuster for external operations through a second jack. The adjuster rotates and carries a pinion which engages a digitally controlled motor operated by the control system.

Title: Contamination and ferromagnetic phase determn. method e.g. for tube - uses spaced variable magnetisation coils operating simultaneously at two test frequencies for geometrical and ferromagnetic analysis
Inventor: SCHNEIDER HEINZ
IPC: G01N27/72
Filed: 1982-05-12
Abstract: The process simultaneously detects contaminations, ferromagnetic phases and non-magnetisable geometric faults in or on paramagnetic materials, esp. in tubes. Three sub-systems are connected to a common processor. The first sub-system contains an exterior differential coil with a superimposed saturating magnetic field. The second sub-system contains an exterior absolute coil with a synchronised superimposed magnetic field. The third sub-system contains an exterior differential coil without any superimposed magnetic field. The frequency of each sub-system is adjustable. The tube under test is moved from one sub-system to the next. Each sub-system gives results for the outer and inner surfaces and for the bulk material. All results are processed, compared, stored and displayed by the common processor.

Title: Centralised hair-drying installation for hairdressing salon - uses remotely sited fan to drive air into main trunk and has individual electric heaters in each air outlet
IPC: A45D44/02
Filed: 1982-06-07
Abstract: The centralised hair drying installation offers the advantage of having the fan and its motor sited away from the user, reducing the noise level to the user. The air is driven to a distribution trunk by the remotely sited fan and heater. Various outlets are provided with a valve fitted in each to control passage of air. The power of the fan motor is increased as each outlet is opened. Once in the outlet trunk the air passes over an electric resistance, having an oscillometer to vary the heating intensity. The hot air passes through a rubber membrane valve to reduce loss of air and then to the fixed or mobile hair drier attached to the outlet.
Patent FR-2531095-A1 (FR)
Inventor: LAISNEY BERNARD
IPC: C08K5/54
Filed: 1982-07-30
Abstract: Provided are single component organopolysiloxane compositions which are hardenable at ambient temperatures and contain as the cross-linking agent silanes with hydrocarbonoyloxy (acyloxy) or ketoniminoxy groups. The compositions further comprise a cross-linking catalyst which is an organic derivative of titanium, e.g., a titanium ester, polytitanoxane, alkanolamine titanate, etc., or an organic derivative of zirconium, e.g., a zirconate, polyzirconate, etc. After cross-linking, the present compositions provide organopolysiloxane elastomers exhibiting good properties. The organopolysiloxane compositions are referred to as "single component" to contrast them with the two-component organopolysiloxane compositions which are not storage stable and must therefore be handled in two separate packages, which problem is overcome by the present compositions.
