Title: Method for welding conduits of thermoplastic material, and device therefor.
IPC: B29C65/22
Filed: 1984-02-03
Abstract: A system for heat-sealing thermoplastic conduits involves a thermoplastic sleeve surrounding an electrically conductive heating wire arranged in a coil. A bridging conductor is located adjacent the heating element, but is separated from it by an insulation layer of predetermined thickness. When the sleeve is heated by supplying electric power to the heating element, the entire heating element generates heat during a first phase in which fusion pressure is applied between the sleeve and pipes being connected. The bridging connector is forced into contact with selected coils of the heating element to initiate a second phase. In the second phase, the heat produced in the area of the selected coils is automatically reduced by short circuiting such coils.

Patent ES-8605733-A1 (ES)
Title: Improvements in rack power-steering systems.
IPC: B62D5/087
Filed: 1985-02-13
Abstract: In a rack power-steering system, the axial movements of a helical pinion meshing with the rack, resulting from torque applied to the pinion, cause corresponding movements of the movable member of a control valve of the system. This is achieved through a transmission including a piston movable axially with the pinion and defining a variable-volume compartment filled with a substantially-incompressible, deformable material, such as a fluid (oil or grease) or rubber, this material being intended to transmit a control pressure to the movable member of the control valve through a rod which may be formed integrally with the movable member or as a separate member. The variable-volume compartment is located at one end of a cylindrical chamber of the box of the system within which the piston is slidable and the latter is located in a position axially intermediate the variable-volume compartment and an end of the shaft carrying the helical pinion. When the variable-volume compartment is filled with fluid, sealing devices are interposed between the piston and the wall of the cylindrical chamber and between the rod and its slide seat so as to isolate the chamber from the exterior. The sealing devices may, for example, consist of two sealing rings mounted on the external surfaces of the piston and of the rod respectively, or, for example, of two deformable diaphragms fixed around their peripheries to the wall of the cylindrical chamber with their central parts pressed against the piston and against the rod respectively by the fluid in the variable-volume compartment.

IPC: F16K1/30
Filed: 1986-07-01
Abstract: A siphon head 304 is configured in order to fit onto the neck 350 of a bottle 352 in a sealed relationship. On the outer surface 360 of the body 362 is mounted a lever 340 by means of breakage filaments and a spring sheet. During use, the user pulls the lever 340 up in order to break the filaments.

Title: Method for laminating a film by applying pressure and heat, and apparatus for carrying out the method.
IPC: B29L31/34
Filed: 1986-09-03
Abstract: Apparatus for laminating a film onto a carrier. A carrier, such as, for example, a printed circuit board, a multi-layer lamination, a metal plate or a carrier layer with metal layers coated on both sides, is heated in a horizontal position on both sides over its entire surface in a heating station and is guided up to a photoresist film which is fixed vertically on suction plates of vacuum tables and which also spans a laminating station located between the vacuum tables. The photoresist film is drawn off from a single supply roll by means of a gripper bar and is guided over the vacuum tables and the laminating station. A cutting device cuts through the photoresist film transversely to its longitudinal direction. The carrier touches the photoresist film at the height of the laminating station, so that the carrier, transported further, is pushed into the nip between the rotating laminating rollers of the laminating apparatus, is grasped by the rollers and transported through the laminating station, together with the photoresist film which is laid onto the top side and underside of the carrier.
