Title: Welding plastic sheets using electrically heated head - incorporating electrical conductors in the form of a braid of flexible electrically conductive material
IPC: B29C65/18
Filed: 1972-10-03
Abstract: Electrical conductors (in the form of a braid of flexible electrically conducting material e.g. copper alloy) are pref. secured between two non-stick insulating plates (e.g. glassfibre) by pref. a heat resistance adhesive, and plastic sheets are pref. pressed against one of the plates by an elastomeric surface presser plate. The conductors are heated by electrical resistance to weld the plastic sheets together along lines determined by the lay-out of the conductors. Long weld lines can be formed (in e.g. tyres, inflatable boats) without damaging the plastic in the region of the weld lines. A reduced voltage across the conductors is achieved.

Title: Reaction rate detector - eg for enzyme-catalyzed chemical reactions with direct reading
IPC: A23L2/76
Filed: 1972-10-20
Abstract: In a reaction rate detector, light projected through a sample and a reference is compared photoelectrically, a difference signal is used to attenuate the signal from the reference light to equal that from the sample light, the reference signal then being maintained at that level, the initial reaction speed is determinend and at a time dependent on this speed the new signal from the sample light is compared with the attenuated reference signal and the difference is used to provide a direct indication of the rate of change of absorbence and hence the reaction rate. The reading interval is automatically reduced for rapid reactions.

Title: Feeding a pile yarn to a loom - through an eyelet which is movable transversely of yarn to increase the yarn path and maintain constant tension
IPC: D03D49/06
Filed: 1973-10-29
Abstract: Pile yarns are woven into two base webs formed simultaneously on a loom whereby the webs are interconnected, and the pile yarns are cut to form two pile fabrics. Each pile yarn is fed from a yarn build on a beam and passed through an eyelet in pref. a vertical rod which is slidable in aligned apertures of upper and lower plates, whereby when the yarn tension decreases and the yarn slackens, the rod falls under gravity to increase the length of the yarn path and maintain constant tension. When the yarn tension becomes too great pref. lifting platforms (actuated by pref. electromagnets) are provided to lift the rods and shorten the yarn path. The rods may be formed by a twisted wire pair; a metal filament in a plastic sheath, or a separate metal weights encapsulated in a plastic sleeve. Several pile yarns can be stored on a single beam, and the tension of the different yarns is individually controlled.

Patent FR-2223753-A1 (FR)
IPC: G06K15/12
Filed: 1974-03-21
Abstract: In the case of a display device in matrix form which responds to the root-mean-square value of the applied voltage, the Xi electrodes are subjected to the voltages eXi. In the sequence of these electrode voltages eXi, both one and the other of the two voltage states (V1, V2) each occur equally often. The Yj electrodes are successively probed with voltages eYj. This produces differential voltages (eXi-eYj) which in the case of non-selected cells always have the same root-mean-square value and in the case of selected cells always have a root-mean-square value of zero. Therefore, the picture brightness is uniform and the contrast is great.
