Title: Interconnection wiring system
IPC: H01R31/02
Filed: 1969-12-04
Abstract: A mounting arrangement for an electrical connector assembly 2, Fig. 1, comprises a pair of spaced rails 10, 12 each having a plurality of inwardly extending ribs 74 which fit over ledges 19 on the connector assembly housing, the ribs on each rail being located opposite one another. The spacing between adjacent ribs is greater than the length of the ledges 19, so that the connector assembly can be inserted, and withdrawn from, between the rails when it is positioned between adjacent ribs. Individual connector assemblies are clamped in position by means of a plate 76, slidable in grooves 80 in the rails 10, 12. Complementary longitudinal projections 86 and grooves 84 in the rails allow two or more mounting channels to be joined. In a modification (Fig. 17, not shown) pairs of connector assemblies may be mounted back to back between rails having upper and lower sets of ribs for abutting upper and lower ledges on the combined connector housings. In each individual connector assembly 2, Figs. 2 and 11, sockets contacts 52 are positioned in a plurality of passageways 30 in an insulating housing 14, so forming a module. A resilient sealing block 18 is bonded to its upper side and has aligned passageways 24 covered by a puncturable membrane 25, through which the plug part (Fig. 3, not shown) is inserted. A compressible barrier insert 38 fits into a recess 34 in the housing 14 and has a plurality of openings separated by walls 40, through which the sockets are inserted into the housing. They are held in position by a closure plate 16, bonded to the housing, which also compresses the insert 38, so forming a peripheral seal. The housing may be of diallyl phthalate, and the sealing members 18, 38 of silicone rubber. Constrictions in the block 18 facilitate gripping of the plug lead. The sockets themselves are made by stamping and bending operations on a laminated sheet metal strip which comprises a base portion of a springy metal such as beryllium copper and a contact portion of a highly conductive metal, for example pure copper which extends over only part of the springy layer. The sockets include both blanked out contact springs and blanked out retaining springs which abut a shoulder on the plug. The plug may be removed by the insertion of a retraction tool which forces the springs outwards off the shoulder. The sockets are moved closer by folding the carrier strip to form bridging portions 70, Fig. 11. By suitable severing of these portions, selected combinations of-sockets only may be commoned. Sockets may be connected by parallel strips 248, 249, Fig. 8, which are themselves joined by rings 253. A socket 252 is located at each end of each ring. (For Figure see next page)

Patent ES-432293-A1 (ES)
Title: Screen tensioning apparatus
IPC: B41C1/14
Filed: 1974-11-26
Abstract: An apparatus for applying a screening material in a frame structure wherein the tensioning of the screen as it is secured in the frame can be accurately determined and the screening material placed in the frame member in a consistent manner over long periods of operation. The screening device employs freely moving or "floating" clamp members which are placed under constant tension. The clamp members hold a screening material in four different directions and maintain the constant tension on the screen as it is forced into grooves in the frame member. The floating clamp members serve to maintain the desired tension at all times in that as the screening material is forced into channels in the frame by means of rods, the clamp members will move in the direction that the screen is being pulled while at all times maintaining the desired tension on the screen as it is press fitted into the channels. In a preferred manner, movable weights serve as the tensioning means and hydraulicly operated piston rods are utilized as part of the floating clamp means which hold the screening material between bar and stationary wall members.

Title: Heat-recoverable articles
IPC: B29C63/44
Filed: 1975-09-26
Abstract: To simplify assembly and to achieve a fool-proof sealing and fixing of the connecting point of elongate objects, a heating device is installed in the enveloping device which, at least in certain sections, is capable of recovering its shape under heat. The said heating device has an electrically conducting polymer material with a positive temperature coefficient of resistance, in order to avoid undesired and harmful overheating. If a current flows through the heating device, the heat thus generated causes the enveloping device to recover its shape and, after recooling, fixes the connecting point in a sealing manner. The fool-proofness is of significance in the case of electrical equipment and installations, quite particularly in the case of electronic equipment and installations.

Patent ES-478901-A1 (ES)
Title: Hydraulic system with unloading valve assembly
IPC: F04B49/00
Filed: 1979-03-23
Abstract: A hydraulic system having a reservoir fed charge pump supplying pressurized fluid through a filter to a supply pump for direction controlled fluid devices includes an unloading valve assembly on the return passage from the devices for limiting back pressure therefrom as long as the charge pump supplies sufficient pressurized fluid for the supply pump. The unloading valve assembly includes an unloading valve movable in response to the pressurized fluid at the connection between the supply pump and the filter to unload the return passage by connecting it to the reservoir and further to control the pressurized fluid going to the filter by connecting the charge pump to the reservoir at a predetermined maximum pressure of pressurized fluid. As the decvices require more fluid from the supply pump causing the pressure to the supply pump to drop, the unloading valve first blocks the charge pump from the reservoir and then the return passage. After the return passage has been blocked, the pressure therein rises to activate a makeup valve provided in the unloading valve assembly which connects the return passage to between the charge pump and the filter to cause return fluid from the devices to feed directly to the supply pump. The unloading valve assembly further includes a signal valve which responds to a predetermined pressure differential across the filter to provide a signal indicative of a clogged filter and to cause the unloading valve to connect both the return passage and the charge pump to the reservoir.
