Title: Microcircuit connector - describes method of fabrication of microcircuit connector
IPC: H05K3/40
Filed: 1973-10-02
Abstract: Microcircuit connector comprises a wager (1) of insulating material supporting at least one conductor (3) having a first (5) and second (4) extremity. The wafer (1) has an opening (2) in it into which the first extremity of the conductor extends. The method of fabrication is to deposit conductorS according to in predetermined positions on a temporary substrate made of a first metal easily eroded by a chemical agent.

Title: Self-priming oil burner feed pump - fast acting valve spool with additional sealing ring controls cylinder clearance and air vent for single-pipe systems
IPC: F04B49/24
Filed: 1973-11-22

Title: Pick-up of infra-red spectrum in water - has an adjustable source and employs infra-red absorption in range 100-150 mu thick
IPC: G01N21/85
Filed: 1974-09-06
Abstract: The infra-red spectrum pick-up system relates to a beam width of 100-150 MU, and having a rectangular cross-section.

Patent FR-2290290-A1 (FR)
Title: Ancillary lips for inhibiting lateral contraction of extruded film - to reduce waste due to thickness variations
Inventor: SMEDT FELIX FREDERIK DE
IPC: B29C48/08
Filed: 1975-09-26
Abstract: Extrusion of thermoplastic film by using a slit die with ancillary lips which remain is contact with the extrudate while allowing lateral expansion and which release the film just before the film impinges on to a quench roll surface. Adherence between the extrudate and the quench surface is enhanced by electrostatic attraction. Used esp. for production of polyethylene terephthalate film. the ancillary lips permit initial expansion laterally as the melt is released from the pressure within the extrusion die proper, but inhibits subsequent lateral contraction in compensation for longitudinal draw down as the extrudate is taken up by the quench surface which is normally run at least marginally faster than the extrusion rate. Losses of material at the film edges by thickening due to excess lateral contraction is therefore reduced.
Patent FR-2329454-A1 (FR)
Title: Universal ellipse tracing machine - has two slides working in guides at right angles to each other and coupled by graduated rule with tool holder at end

Title: Fluid control valve using piston in perforated cages - has nested cages with perforations communicating with circumferential grooves
Inventor: VINCI MICHELE
IPC: F16K1/54
Filed: 1975-12-02
Abstract: A regulating valve with a body and a piston type stopper which slides in a system of cylindrical cages with perforations in them. These are uncovered progressively during piston movement and so dissipate the greater part of the kinetic fluid energy when the valve closes. The size of the perforations is calculated in accordance with the speed of the fluid and its pressure drop going through the valve. The stopper part can be balanced simultaneously internally and externally. The arrangement lessens wear due to erosion and also noise. It is particularly applicable to high pressure drop valves.
