Title: Pivot pump tube communicating with coaxial outlet pipe - has means for separating higher density materials from pumping fluid
IPC: F04D1/12
Filed: 1974-05-03

Title: Low distortion speech transmission - by adding small amplitude alternating signal to microphone signal before squaring
Inventor: BOUVIER PIERRE
IPC: H04B14/00
Filed: 1974-12-04
Abstract: The system uses a rectangular signal produced by lopping the peaks off a microphone signal. Before doing so, an auxiliary alternating signal of relatively small amplitude is added to it. A Schmitt bridge can be used to transform the composite signal into a rectangular one, and the degree of lopping achieved by the bridge can be less in absolute value than the minimum amplitude of the microphone signal to be transmitted. The amplitude of the auxiliary signal can be between the lopping level and the minimum microphone signal amplitude. The auxiliary signal can be at inaudible frequency.

Title: Fixing flexible coverings on tubular frameworks - has split tubular clips holding covering edges around frame members
IPC: E04H15/64
Filed: 1975-01-08
Abstract: A method of fixing sheets of flexible covering material to tubular frameworks involves using longitudinally split tubular clips holding the covering material on frame members. The internal diameter of each clip is slightly less than the external diameter of a frame member and its peripheral length is typically two thirds that of the frame member. For assembly, the edge of the covering material (7) is rolled around the frame member (c) and a clip (8) is sprung on to clip the material in position. If desired, one clip may be put on top of another so that adjacent walls of the structure may be made of different flexible materials. For more permanent fixing, the clips may be retained by screws or staples.

Title: Three-dimensional parts identification device - can select parts from loose set of parts by using hologram and analysing unit
IPC: G06V10/88
Filed: 1975-06-24
Abstract: A device for the identification of three-dimensional parts is used to select parts from a loose set of different parts. It is based a selection strategy, the choice of a characteristic of the part, a multiple hologram filter, a scan of the loose parts and the measurement of a correlation signal. The hologram filter is formed between two lenses. A laser is used to project coherent light onto the loose parts. Part of the light beam from the laser is reflected by a semi-transparent mirror and along a direction parallel to the optical axis of the lenses. An automatic analysis device is used to detect the maximum light intensity of correlation responses appearing in the focal plane of the upper lens.

Title: Cooling winding slots for electrical machines - have coolant circulation driven by rotor centrifugal force
Inventor: BERTHET MICHEL
IPC: H02K55/04
Filed: 1975-07-01
Abstract: The slot design is suitable for electrical machines, particularly cryo-alternators using superconductors. The coolant circulates around the conductors in the slots preventing local heating and conductor damage. The rotor is reinforced with glass-fibre and is in four polar sections. Slots to carry the rotor winding and coolant over its length are approximately rectangular in shape. The conductors are held within the slots by insulating ribs providing a free surrounding space several millimetres deep. Further slots alternate with those holding the conductors so that the cooling is more even. Circulation through the slots and around the conductors is maintained by the centrifugal force of the spinning rotor.

Title: Belt type yarn feeder, esp. for false twist texturing - is easily threaded and has driven belt pulley
Inventor: CROUZET CHARLES
IPC: B65H59/10
Filed: 1975-11-13
Abstract: A belt-type yarn feeder, esp. for false twist texturing machines, but applicable also wherever the yarn must be fed at a strictly controlled speed, has a driving shaft in comon with a number of processing stations on the machine. A pivoting bracket carries two pulleys on shafts parallel to the long axis of the driving shaft, and a pivoting yarn support cylinder can be brought into contact with an endless belt running on the two pulleys, one of which is rotated directly by the common driving shaft. The driven pulley is attached to a pull-off spring so that tension is maintained on the belt. The device is simple, cheap to mfr., takes up very little room and is easily threaded whilst the machine is running.
Patent FR-2337571-A1 (FR)
Title: Automatic continuously fed gravity separator - for separating non-miscible liquids of different densities
IPC: B01D17/02
Filed: 1976-01-06
Abstract: The equipment comprises two pumps and a cylinder domed at the top and tapering to a cone at the bottom into which the mixt. is fed. This cylinder contains the feed pipe and two concentric cylinders. The pure water collects in the inner cylinder in which is a level gauge. When the water level reaches the higher level probe the pump connected to the water outlet pipe automatically starts to pump out the water into a collecting tank. When the water level drops to the lower level probe the water pump stops and the oil pump starts to pump out from the middle cylinder. This continual alternating operation of the pumps results in a lowering of the press. within the outer cylinder to about 600 mm of mercury. The mixt. to be sepd. is thus drawn into the separator under the influence of the press. difference. The equipment is partic. useful for sepg. water and hydrocarbons because the mixt. is not pumped into the equipment, the agitation, and therefore the formation of emulsions which occur under such conditions is avoided. This results in a more efficient sepn. and reduces the necessary size of the separator. The continuous feed arrangement and greater efficiency, results in a redn. of operating costs.

To change the powder source the repose position of the radius arm (25) is altered.

Title: Cooling system for diesel engine injection nozzles - includes control throttle operated by engine to regulate fluid flow
IPC: F02M53/04
Filed: 1976-06-04
Abstract: A pump draws water from a reservoir and delivers it through a filter to the cooling passages surrounding the fuel injection nozzle. The water returns from these passages through a throttling valve and a cooler to the reservoir. The throttling valve is controlled from the engine to vary the flow of cooling water in the circuit in dependence on the power developed by the engine. The flow is kept to a rate such that the water in the cooling passages is brought to the boiling pt. at the press. reached in this part of the circuit. Since cooling is thus carried out by evaporation it proceeds at a constant temp. which does not vary with engine load.
