Title: Potato defoliation using diquat or paraquat - and a urea or triazine herbicide as photosynthesis inhibitor
IPC: A01N43/70
Filed: 1974-11-15
Abstract: Process for the destruction of the foliage of potatoes is by the application of a mixture of a diquat (1,1'-ethylene-2,2'-bipyridilium) or paraquat (1,1'-dimethyl-4,4'-bipyridylium) salt and a photosynthesis inhibitor chosen from urea and triazine herbicides. Destruction of potato foliage facilitates mechanical harvesting of the potatoes, stops propagation of potato mildew (Phytophthora infestants) and controls the size of seed potatoes. The disadvantages of defoliation with dessicants are (a) browning of the vascular tissue and (b) necrosis at the point where the stoton enters the tuber which may lead to secondary bacterial and cryptogamic rot i.e. stem-rot. Use of the photosynthesis inhibitor avoids the basal necrosis.

Patent FR-2282494-A1 (FR)
IPC: D03D47/48
Filed: 1975-08-19
Abstract: The process provides insert strips which are not stretched even when the spinning materials undergo pronounced weaving shrinkage. So that the apparatus is suitable for simple production and a compact design, its gripper clamps (13, 14) are brought onto the front side of the weaving comb (R). The pattern movement (A-B-C-D) of these gripper clamps before the weft-thread ends are cut off is different from that (D-A) after they are cut off. During this second phase of movement, the weft-thread end is hooked onto a needle which inserts it into the next shed. Two control mechanisms coupled to one another effect the movement of these clamps. A gripper sliding piece (8) slideable towards the weaving comb (R) and back is moved by one control mechanism (22, 24, 26) in such a way that a vertical movement generated by the other control mechanism (2, 3, 20, 7) brings about a corresponding movement of the gripper sliding piece (8) and of the parts connected to it towards the weaving comb and back.

Patent FR-2313544-A1 (FR)
IPC: E06B9/84
Filed: 1976-05-31
Abstract: A shaft butt (8) bearing driver discs (9, 10) is coupled to the horizontal winding spindle of the roller door or roller blind. An inertia member (14) is mounted on a bearing pin (11) which is axially parallel to the shaft butt (8) and is located at the edge of the driver discs (9, 10). Said inertia member is designed as a detent pawl and works in conjunction with the inner toothing (2) in a housing (1) enclosing the entire arrangement. If the roller door or roller blind unwinds at an excessive rate, e.g. if the bearing means or drive means of the same are faulty, the winding spindle is locked by the inertia membrane (14) being swivelled outwards by its moment of inertia, counter to the force of the spring (16), and comes into engagement with the inner toothing (2) of the housing (1). This securing means responds more quickly than those which operate with the action of centrifugal forces, the risks going hand in hand with the unintentional unrolling of roller doors or roller blinds thus being further reduced.
