Patent FR-2438845-A1 (FR)
Title: Crank shaft signal evaluation circuit for IC engine - applies signal to comparator which controls, variable ratio voltage divider via time constant circuit
IPC: G01P3/46
Filed: 1979-10-09
Abstract: The evaluation circuit is for electric signals, which are generated according to the rotation of a shaft i.e. crank shaft or an Internal Combustion engine. The signals are delivered by an inductive leakage field pickup, depending on an i.c. engine crankshaft rotation. The signal amplitude and frequency increases with the shaft speed of rotation. In order to control the amplitude of signals, they are applied through a series resistor (R1) to an inverting input of a comparator (K). The resistor (R1) and a transistor (T1) emitter-collector path form a variable ratio voltage divider. Comparator (K) output is connected through a differentiating capacitor (C2) to a time constant circuit consisting of a capacitor (C1) and a resistor R4). It voltage rises with frequency and reduces the transistor (T1) internal resistance. A resistance (R2) with a load current conductor (M) is connected to the differential capacitor (C2), and a control diode (D2) to a storage capacitor (C1), so that the storage capacitor is connected to the load-current conductor.

Title: Rocking table to stimulate breathing of premature babies - uses pneumatic bellows to rock table at electronically controlled rate to stimulate maternal breathing
Inventor: DUVIVIER CLAUDE
IPC: A61H31/00
Filed: 1980-02-29
Abstract: The breathing of premature babies is stimulated by placing them on a flat surface which rocks slightly at a frequency of 15 to 20 oscillations per minute to simulate the maternal breathing rhythm as seen by the foetus. The rocking table (7) is pivoted (9) near its centre and is raised by a bellows (11) and falls under gravity. The filling and emptying of air from the lifting bellows (11) is controlled by a solenoid valve (12) An air pump (25) supplies an air reservoir (26). Air is drawn from both pump and reservoir and passes through safety and alarm devices (S,A) which signal irregularities in pressure or flow of air to the bellows. An adjustable electric oscillator (1A), which controls the rate of operation of the solenoid valve, allows various rocking rates to be set.

Title: Turbulence generating flow meter - has torsional measurement sensor whose induced rotational oscillation frequency corresponds to flow rate
Inventor: HERZL PETER J
IPC: G01F1/32
Filed: 1980-04-24
Abstract: A turbulence generating flow meter with a torsion sensor operated by flow resistance has a turbulence generating body (11) placed in the flow tube (10) producing turbulence alternately on both edges at a repetition rate proportional to flow rate or speed. The generated eddy currents move up the right and left tube sides. The turbulent frequency remains in an accurate relationship with the flow speed despite attenuations due to fading, turbulence, flow speed variations etc. which tend to degrade the relationship in conventional devices. A sensor (12) mounted torsionally downstream of the turbulent body has relatively broad parallel arms (12A, 12B) with an orifice between them and symmetrically about the sensor rotation axis (Y'). The eddy currents produce alternate clockwise and counter clockwise torques on the sensor by acting alternately on each arm. A sensor (19) detects the oscillation frequency which is proportional to flow rate.

Title: Retractable blade guard for fabric slitting machine - linked to machine lid for automatic operation when opened
Inventor: PISANI LUIGI
IPC: D06H7/18
Filed: 1980-09-25
Abstract: A slitting device for rolls of fabric, having a revolving circular blade, is enclosed in a container with a lifting lid which is linked with a blade guard, whereby opening the lid causes the blade to be covered by the guard, which is withdrawn when the lid is closed. At each end of the container is a lever which controls the position of the blade guard and which is depressed by the lid when closed to raise the guard from the blade. Opening the lid allows the levers to raise and the blade guard to drop over the blade. Blade and guard are mounted on horizontal guides which permit them to be moved horizontally in unison to alter the position of the cut. This arrangement gives reliable protection in a simple, inexpensive construction.
