Title: Crucible for mfg. monocrystalline gallium arsenide - using mat on crucible wall to prevent dislocations
Inventor: BESSELERE JEAN-PIERRE
IPC: C30B11/00
Filed: 1976-03-23
Abstract: Crucible is for mfg. an ingot by controlled progressive crystallisation in a horizontal direction from the liq. phase. Between at least one part of the internal wall of the crucible and the liq. is a thin mat of refractory fibres, coated with a thin layer (1) of a substance which strongly absorbs thermal radiation. The mat may be coated on either side or on both sides with layer (1), and the pref. mat consists of silica fibres with a layer (1) formed by impregnating the mat with carbon or using the silica mat with a graphite fibre mat forming layer (1); a refractory sheet may also be used on the outside of the crucible.

Title: Pneumatic shift register sequence control - has threshold gate to ensure interlock signal line pressure is below given pressure
Inventor: BOUTEILLE DANIEL
IPC: F15C4/00
Filed: 1976-04-16
Abstract: An interlocked sequence control of processes using pneumatic valves is based upon a shift register technique using stages that ensures correctness of operation by requiring a specific signal pressure before the sequence may advance. Each side of a pneumatic cylinder is controlled by a signal (7) from a shift register stage (40), consisting of a bistable function (41), threshold gating (36) and interstage gating. When the signal from an actuator limit switch (16) is too high the threshold gate output (30) is low and the bistable is not set to generate an output (7). When the time has evacuated the pressure falls and the bistable changes state. The interstage gate (13) allows successives stages to be set to advance the sequence.

Title: Optical measurement of local fluid flow velocity - using rotatable optical barriers and determining transit times of diffuse particles in suspension
Inventor: BOUTIER ALAIN
IPC: G01P5/20
Filed: 1976-05-25
Abstract: The optical measuring technique is for determination of the local flow velocity of a fluid containing diffusing particles in suspension. A simultaneous determination is made of the direction and intensity of the velocity vector relative to a system of reference areas and a measurement zone of these dimensions is defused using two rotatable optical barriers. The time interval taken for each particle to travel the distance d between the two barriers is determined. This is achieved by creating two parallel monochromatic light beams (2, 3) in the measurement zone (1). The passage times t1 and t2 of each particle over each barrier are then memorised and the interval (t1-t2) is determined. By rotating the barriers, a position for which the interval is minimal is found and from this position, and the value of the min. the velocity vector is determined.

Patent FR-2344999-A1 (FR)
IPC: H02K25/00
Filed: 1977-03-17
Abstract: An electric motor having in each of the rotor and the stator a permanent magnet and an electromagnet of equal strength placed in parallel relation such that when the electromagnet coil is activated the flux of the magnets is additive and when the coil is deactivated the flux of the permanent magnet takes a closed circuit path through the electromagnet core, the rotor being mounted on a shaft for rotation relative to the stator and a commutator switch being included for alternately connecting and disconnecting the electromagnet coils to and from a power source, wherein capacitors are provided in the coil circuit. The capacitor and coil circuit is designed to have a resonant frequency roughly equal to or near the switching frequency of the commutator switch at the intended shaft operating speed, thereby causing the capacitors to alternately store energy from and discharge energy to the coils. The combination of permanent magnets with electro-magnets and the addition of capacitors in the coil circuit to form a resonant circuit results in increased efficiency of the motor.

Title: Tubular film extrusion die with low pressure melt zone - contg. screens to suppress spider lines or other circumferential variations
IPC: B29C48/08
Filed: 1977-11-07
Abstract: A die for extrusion of blown thermoplastic tuning incorporates an annular passage which temporarily increases in depth to depressure the melt while it flows through one or more fine mesh screens bridging the channel. This low pressure zone is downstream from any fins which traverse the flow to support the core mandrel. Used for extrusion via static or rotary die systems. The fine subdivision and recombination of the flow followed by repressurisation when leaving the deep section passage for the shallow outlet die passages suppresses any residual 'spider' marks from flow round internal mandrel supports or other baffles.

Title: Rotary valve sealing system - has extension on operating spindle with housing incorporating spring and seal arrangement
IPC: F16K5/06
Filed: 1977-12-15
Abstract: The valve, with horizontal in line ports (11) has a curved valve member (12) between, which is swung open and shut about a vertical axis (25). The valve spindle (16) is enclosed by a sleeve (22) enclosing in turn an upper spindle extension (25). The top of this sleeve is internally threaded to receive a plug (24) with an operating handle (30) attached to it, projecting horizontally. Between this plug and the bottom of the interior or the sleeve is an annular space containing a return spring (27). This acts against a ring (28) inside, tending to push the spindle upwards against the block (24). A system of sealing rings (31, 32, 23) gives a very good seal additional to the conventional sealing rings (17) inside the body (10).

Abstract: The ski binding comprises a pivotable sole support (13) which is coupled to the heel support (39-44) by means of a connection, for example a toggle lever (29, 33), which can be shortened. The heel support is assigned an extension (46) directed to the rear in a fixed reference position. The extension (46) is inserted under a holding-down means (48). The connection (29, 33), which can be shortened and is locked in the extended position when the boot (12) is firmly clamped in, serves to introduce the extension (46) in the holding-down means (48) for downhill skiing and thus to fix the heel support (39-44) on the ski (10) or for cross-country skiing it serves to take the extension (46) out of the holding-down means (48), as a result of which the heel support (39-44) is released to pivot about the pivot axis of the sole support (13).
