Title: Pulse shaping or regeneration circuit - uses a Schmitt trigger and memory with two parallel networks
IPC: H03K5/12
Filed: 1974-04-19
Abstract: The method for regenerating or correcting the deformation of pulse rise and fall shapes, particularly in the field of telephone network automatic switching where such deformation may be considerable and where signal levels may vary by several dBs. The technique employs a Schmitt trigger circuit fed from a memory block. This block is fed from two parallel networks connected to the pulse input circuitry. The first network has a linear transfer characteristic providing a delayed trigger to the Schmitt circuit. The second network provides a correction using the trailing slope of the input pulse.

Title: Listening buoy launched from aircraft - has float and sinker connected by cable with connection device between
Inventor: HAROU CLAUDE
IPC: B63B22/00
Filed: 1975-06-26
Abstract: A submarine detecting buoy has a container protecting the submersible portion having a hydrodynamic profile, which assists the sinking of the weighted part of the assembly.

Title: Detection of solids entrained in a gas - e.g. sand in natural gas from underground storage, using vibration transmitter in gas stream and transducer outside pipe
Inventor: CHERON JEAN-JACQUES PAUL MARCE
IPC: G01N29/04
Filed: 1975-07-02
Abstract: The detection device comprises a pick-up of shocks provided with a transducer, e.g. of piezo-electric type, capable of converting shock waves produced by the particles into electrical signals, which can be manipulated in an electric treatment circuit. This is modified in such a way that the transducer is mechanically coupled to a vibration transmitter subjected to the bombardment of the particles and located wholly on the outside the pipe into which the transmitter penetrates. The electronic treatment circuit is one in which the shocks caused by the impact of the particles on the vibration transmitter are counted. The device enables the piezo-electric crystal to be adequately protected yet easily accessible, while the vibration transmitter can be designed to resist the bombardment of the particles entrained by the gas and can be specially treated to resist erosion. The device enables the solids content to be monitored to prevent damage to valves etc. in the pipeline.

Title: Light sensitive musical instrument - uses series of gate circuits which are controlled by photoelectric cells
IPC: G10H1/18
Filed: 1975-07-02
Abstract: The instrument permits, switching, mixing and routing of electrical signals, by the action of lighting variation. The instruments is made up of a group of circuit whose signal transmission resistance varies according to an exterior determined parameter. These circuits are called 'gates'. The opening and closing of each of these gate circuits are triggered by means of a photoelectric cell. This cell, modifies, under the action of variation of its illumination, the rest (normal) position of a semiconductor element. The result is to affect the transmission of an input signal towards the circuit and in consequence, the amplitude at the output of the circuit.

Title: Pump peak pressure absorption system - varies volume available for fluid under control of pressure peaks themselves
Inventor: BASTENHOF
IPC: F04B11/00
Filed: 1975-12-10
Abstract: The system absorbs peak pressures occurring in a pump inlet or outlet when the pump chamber is connected to one or the other, by varying the volume available for the fluid at one or more first positions.
