Title: Pulverulent flow rate sensor e.g. for paint or enamelling material - has detector sensitive to electric charge on conduit wall produced by friction from flow
Inventor: CREPEAU ANDRE
IPC: G01F1/64
Filed: 1981-11-06
Abstract: The device has a sensor (11) situated outside the pipe carrying the flow to be determined. The sensor (11) detects the electrical charge resulting from the friction of the product against the pipe's (10) inner wall. The sensor (11) is a conductive component which is placed either near or in contact with the pipe (10). It can partially or totally surround the pipe (10). A circuit gives a signal as a function of the voltage between the axial ends (13,14) of the sensor (11). This signal is used e.g. to send an alarm signal or to stop a control installation. The voltage is measured by a high input impedance amplifier. A smoothing capacitor is situated between the output terminals of the sensor.

Title: Opto-electronic fruit diameter measuring appts. - projects real size shadow of fruit on plane with photoreceivers arranged in V=shape
IPC: G01B11/00
Filed: 1982-06-22
Abstract: The appts. has an extended light source (2) emitting parallel rays (6) which illuminate the fruit whose diameter is to be determined casting a real-size shadow (4) on a plane pickup (3). Two lines of small phototransistors (5) arranged in a 'V'shape on the pick-up are used to analyse the extent of the shadow. The diameter is measured along two mutually perpendicular directions. The phototransistors are interrogated successively following a zig-zag line sweeping alternately from one branch of the 'V' to the other. They are connected via a multiplexer to a microcomputer which identifies each one by its binary address and counts the number of 'points' situated in the shadow. The appts. may be used on all fruit calibrating machines which have alveolar transporters.

Title: System for transforming wave energy from the sea into mechanical energy
IPC: F03B13/18
Filed: 1983-09-07
Abstract: The undulating motion of the passing sea waves produces a vertical thrust on at least one float 1. When the float 1 rises, it transforms the mechanical energy using levers 2, a shaft 8 and gear trains 3, thus exerting a torque on the shaft, which in turn exerts a similar torque on the gear train. The torque on the gear train is transmitted to a final pinion by well-known means. The number of floats and the distance between them depend on the characteristics of the waves and the region of the sea selected.

Title: Power amplifier with slaved supply
Inventor: BASIRE ALAIN
IPC: H02P7/285
Filed: 1983-09-27
Abstract: Power amplification circuit for control of DC motors. To minimise the power dissipated in the supply transistors, without risking disturbances produced in the motors by the chopping amplifiers, the supply voltage V<+> and V<-> of a second power amplifier 2 is slaved to be greater, by just a few volts, than the output voltage VM. The variable supply voltage can be provided by a first chopping amplifier 1 using triacs, in particular with optical control. The power amplifiers 1, 2 are chosen to operate with a supply voltage little greater than the output voltage VM: two MOS transistor circuits, including one with optical coupling, are proposed. The filtering of the supply voltage is preferably of LC type.
