Title: Inserting a dummy bar when starting continuous casting - by rolling the dummy upstream on top of the horizontal rolls
IPC: B22D11/08
Filed: 1973-05-28
Abstract: From its storage location at the end of the guide and support rolls, a dummy bar is carried along the top of the rolls while they are still extracting the tail-end of the continuous-cast bar, i.e. the dummy moves in the opposite direction to the cast bar and travels to its entry point in the guide-rolls; the wt. of the dummy and/or pressure is used so the rolls convey it upstream, i.e. towards the mould. The dummy is pref. inserted in the roll-train by lifting >=1 rolls as soon as the end of the cast bar has passed this point. By using this device, a substantial redn. is obtd. in the time lost between each casting cycle.

Title: Fuel injection pump for supercharged engine - advances commencement of injection for partial load for idling operation
IPC: F02M59/26
Filed: 1975-01-29
Abstract: The pump is intended for combustion engines, particularly supercharged engines running at constant speed. Partial load or idling operation is achieved by advancing the moment at which injection commences relative to full load operation. This is preferably effected by the use of a rotatable plunger (1) provided with an inclined control surface (2) on its periphery which controls the moment at which the pumping action starts by closing the suction port (3). This moment is further delayed by rotating the plunger such that the suction port (6) is closed later. A further control surface (5) may be provided which determines the end of the injection by opening port (4, 7).

Patent FR-2300640-A1 (FR)
Title: Continuous casting mould - shaped to prolong contact between steel strand and mould walls and increase heat transfer
IPC: B22D11/04
Filed: 1975-02-14
Abstract: Continuous casting mould has a substantially rectangular mould passage with the major portion of the surface of two opposed walls (3,4) being convex in transverse cross section. The radius of curvature of the convex surfaces is progressively great at successively lower cross sections through the mould wall. The mould is used for the continuous casting of steel strands. The radii of curvature of the convex surface at successively lower cross sections conforms to the known or estimated shrinkage thus reducing air gaps and increasing the heat transfer from the strand through the mold. As contact between the casting surfaces and mould surfaces is contained, thus eliminating air gaps, longer mould can be used thus producing a thicker and stronger shell within the mould.
Patent FR-2264144-A1 (FR)
Title: Variable cross section pile for landing quays - has constant bore diameters and variable outside diameter
IPC: E04C3/30
Filed: 1975-03-14
Abstract: The pile with a variable cross section is used as a member for flexible piling wall and has a constant bore and a variable cross sectional area which ensures that the second moment of area of the cross section varies along the pile length. The pile is flexible and able to withstand bending impact loads produced by ships. Hence the highest second moment of area is arranged at about mid length of the pile. This pile is readily driven into the ground because of its smaller diameter at the ends and hence less soil is rolled away and less energy is absorbed on driving. The pile has a constant bore and variable cross section with individual sections with variable diameters. These simple sections are joined by a shrinking method in order to eliminate expensive rolling processes.

Patent FR-2289398-A1 (FR)
IPC: B65D88/10
Filed: 1975-11-03
Abstract: In a tank blowmoulded from thermoplastic, the opposite side walls are provided with tapers which abut against one another in the centre of the tank and are welded in a liquid-tight manner against the abutting surface. At least one of the abutting surfaces (8, 8') is provided with a surrounding depression or with a plurality of depressions (10, 10') extending over partial regions. These depressions extend outwards as far as the vicinity of the abutting edge (14) and, during pressing in during the welding operation, effect a material displacement towards the abutting edge. This leads to an extremely stable, bead-like weld edge between the two tapers (4, 4'). This effect can be further reinforced by pressing the tapers (4, 4') together in such a manner that the wall thickness of the abutting point (6) is smaller than the sum of the wall thicknesses of the two tapers (4, 4') before welding or pressing together.

Title: Comparative linear measurement of mechanical parts - employs pneumatically operated mobile contact providing signals for pneumatic logic elements
IPC: G01B13/02
Filed: 1975-12-31
Abstract: Checking of linear dimensions of mechanical parts is effected by a comparator with a mobile contact which is operated by compressed air. The same air supply is used for handling control after measurement. A mechanical part is measured by contact with a yoke (27) w.r.t a reference surface. Shafts (7, 8) slide in guides (3, 6) terminated by a jet carrier (10) which is joined by flexible pipe (11) to a compressed air supply connection (12). These shafts and jet provide signals for measurement while a double acting pneumatic jack (5) and shaft (9) control movement of the yoke. These signals enter pneumatic logic elements (R.P.A.M) which effect the measurement comparison and control activities to accept or reject the parts.

Title: Sealing method for spot welded joints - uses metallic globules mixed with plastic sealing compound and fused by welding arc
IPC: F16J15/14
Filed: 1976-03-19
Abstract: To seal the gap between the metal sheets (1, 2) when they are spot welded by the electrodes (3, 4), a mixture of metallic globules (12) and a plastic sealing compound (11) is used. The material of the globules is suitable for welding to the sheets so that the globule (7) which lies in the path of the welding current is fused to both sheets. For convenience of manufacture the globules (12) and plastic sealing compound (11) may be supplied in a deformable tube which is flattened by passing it between rollers before applying it to the joint surfaces. Globules which are a mixture of metal and ceramic may also be used.

Title: Mechanical compass arm for remote handling by slave arm - has secondary framing forming pin-jointed parallelogram and has jack negating arm weight
Inventor: GERARD PAUL
IPC: B25J19/00
Filed: 1976-04-12
Abstract: The mechanical compass type handling arm (FBA) has secondary framing (EDC) with a hydraulic jack (R) to negate the effects of gravity. The arm cantilevers from a static pin joint (F) and has an intermediate knuckle joint (B).

Title: Electronic fuel injection system - uses piezo-electric transformer with bridge switch to reduce resonance
IPC: F02D41/32
Filed: 1976-09-17
Abstract: An electric fuel injection system has a circuit in which an oscillator feeds a piezo electric transformer (1) fitted to a fuel injector nozzle. The nozzle contains a ball valve closing the fuel valve seat by reason of fuel pressure. Ultrasonic energy applied to the piezo electric transformer causes the ball valve to vibrate on its seat to allow fuel to enter the air intake manifold. The oscillator contains a bridge switch to reduce vibrations after the end of each regulator impulse. The bridge switch is fed from the secondary winding of the transformer (6) whose primary winding is fed by two transistors (7, 8) working as amplifiers.
