Patent FR-2472969-A1 (FR)
Title: Plastic injection moulding control - with two parallel hydraulic supply lines and one programmed pressure control valve
Inventor: TITTMANN EGON
IPC: B29C45/82
Filed: 1980-12-22
Abstract: A hydraulic control system for the injection unit of a plastic injection moulding machine for various pressures is based on two parallel supply lines from a variable displacement pump to the injection cylinder. The first includes a pressure reducing valve, a restrictor valve and an accumulator. The second includes an adjustable restrictor and a directional control valve. The pump control unit, the pressure reducing valve and a pressure relief valve at the junction of the two supply lines are governed by a programme controlled valve. This system requires only one programme controlled pressure regulating valve which is of universal use. The necessary pumping capacity is low but the losses are reduced.

Title: Web winding appts. with automatic mandrel changeover - has empty mandrel mounted on swinging arms with bearings opened by cylinders
Inventor: STEFFEN ANDRE
IPC: B65H19/22
Filed: 1981-02-19
Abstract: Web winding appts. in which a full reel is swung out of position by a pair of arms and the next winding mandrel is swung into the winding position by another pair of swinging arms has an adjustable stop at the end of each arm, resting on a bearing on a cutter assembly with a blade which severs the web. Each mandrel is mounted on two spigots each with a driving ring frictionally driven by two rollers. One roller is in contact with a driving drum, the whole being carried by the arms. These spigots are fitted into automatically opened bearings with the open tops closed by moving caps which swing about an axis formed by pins through the arms. These taps are closed by latches operated by a cylinder.
Patent FR-2502391-A1 (FR)
Inventor: LEFEBVRE JEAN CLAUDE
IPC: H01H50/36
Filed: 1981-03-23
Abstract: The yoke (1') of the relay has toothed attachment tabs (16, 16') which can be pushed into corresponding recesses in the baseplate (2'). During assembly, the yoke (1') with its attachment tabs (16, 16') is initially pushed into the recesses by a predetermined amount and the armature (7) is then pressed against the core. The forward movement of the spring (9) supporting the moving contacts (10) is measured. The yoke (1') with its attachment tabs (16, 16') is then pushed further into the recesses of the baseplate (2') by an amount corresponding to the difference between the measured forward movement and the required overtravel. The movement of the armature (7) and of the yoke (1') preferably takes place with the aid of stepping motors. In this way, the contact pressure of a relay can be set reliably during assembly.

Title: Roof timber jointing by microwave hardening of adhesive - applied to prepared ends and heated in multimode cavity
Inventor: MENAUT JEAN GASTON
IPC: B29C65/14
Filed: 1981-04-02
Abstract: Two sets of timbers (a,b) at a time are propelled by a screw jack (12) into open-ended multimode waveguides (7) and are secured by locking screws (11). The ends previously prepared for jointing are glued and subjected to microwave irradiation from both sides (4,5) via lateral branch waveguides (6) connected to power magnetrons. The rate of advance of the timbers is adjusted so that the adhesive is entirely hardened when the microwave heater carriage (9) attains the end of its track (13). Pref. the adhesive is "Resorcine" with a hardening time of about 30 seconds. Legal protection is claimed also for a device for implementing this method, for a continuous rafter jointing chain incorporating such a device, and for timbers formed from rafters jointed thereby.

Title: Integrated circuit socket for circuit boards - has doubly-curved female contact forming heart-shaped transversal cross=section
Inventor: CARAMELLE HENRI
IPC: H01R13/11
Filed: 1981-06-11
Abstract: The socket is made in a conventional insulating base which has chamfer-sided entrance holes at the conventional pitch in its upper and lower surfaces. Each contact unit is inserted into a rectangular cavity from the lower-side entrance hole. Protruding notches (111) in the rectangular shaft (101) are deformed elastically upon entry and catch in internal recesses (71) which prevents further movement. The female end of the contact consists of a doubly curved sheath presenting two lobes (46) convex inwards. An inserted pin is forced by the inward-acting elastic force against the outer curved wall (47) whilst the inner face of the pin is pressed against both ends of the lobe extremities. Contact along four lines in the pin surface is achieved.

Title: Bed joint compensation for prefabricated blockwork panel - rotates alternate courses through half turn in plan before placing in panel
Inventor: LINGL HANS
IPC: E04C2/04
Filed: 1981-09-17
Abstract: The handling machine makes prefabricated panels of coursed masonry and compensates for the cumulative effects of misalignments in bed joints. The machine feeds horizontal lines of bricks, for placement on a mortar bed which has been previously applied to the last placed course of the panel under construction. The compensating process entails reversing every second course by rotating it through 180 degrees in plan and before placing it in the panel. Nominal longitudinal depth tapering of precast blocks, is thus, compensated for as the work proceeds.
