Patent FR-2437648-A1 (FR)
IPC: G04F10/00
Filed: 1979-09-27
Abstract: A time duration is measured precisely and with high resolution by making three time measurements as shown in FIG. 5. The time difference tA between the leading edge of a start signal and the next following leading edge of a constant frequency time base signal is measured. The number "n" of the following leading edges is then counted including the leading edge of the time base signal following a stop signal. The number n is multiplied by the period TQ of the time signal. The time difference tE between the leading edge of the stop signal and the next following leading edge of the time base signal is measured. The real time difference  DELTA t is then calculated as follows  DELTA t=tA+nxTQ-tE. A three part real time measurement is performed to correct the calculated result for drift and aging. Calibration measurements are made and the respective calibration factors are used in calculating the final results. The respective circuit arrangement includes a start channel, a stop channel, and the corresponding supporting circuits.

Patent FR-2445653-A1 (FR)
IPC: H02P8/02
Filed: 1979-12-24
Abstract: An electronic timepiece has a stepping motor comprised of a stator, rotor and driving coil. A wave shaping circuit produces normal driving pulses and correction driving pulses having a longer pulse width than the normal driving pulses. A rotor rotation detection device detects rotation and non-rotation of the rotor after normal driving pulses are applied to the driving coil and in response to detection of a non-rotation condition, a correction driving pulse is applied to the driving coil. A magnetic field detection device detects the presence and absence of an external alternating magnetic field and in response to detection of a magnetic field, a driving pulse of longer pulse width than the correction driving pulses is applied to the driving coil to effect rotor rotation. The magnetic field detection device operates before the normal driving pulses are applied to the driving coil so that in the event of detection of a magnetic field, a driving pulse of sufficiently long pulse width will be applied to the driving coil to effect rotor rotation. In response to detection of an external alternating magnetic field by the magnetic field detection device, operation of the rotor rotation detection device is inhibited thereby conserving power and preventing mis-operation of the stepping motor.

Title: Ultrasonic generator with short circuit protection - uses piezoelectric element protected by diode and resistor circuit responding to high current
IPC: H04R3/00
Filed: 1980-03-11
Abstract: The circuit protects an ultrasonic generator against short circuits. It comprises input transformer (Tr1) and output transformer (Tr2) with alternate switched output transistors (T1, T2). The output is superimposed on a d.c. voltage. The piezo-electric crystal (S) is protected against short circuits by a diode (D2) and high current resistive monitor (Si) coupled to a resistor (R1) bridging the input transformer. A short increases current and voltage across the resistive monitor (Si) which the diode (D2) protects against. The inductive circuitry of the input and output transformers couple with the diode circuitry to suppress back EMF surges.

Title: Microscope eyepiece with self lubricating internal sleeve - to eliminate use of grease to ease axial extension
Inventor: VINCENT PIERRE FELIX
IPC: G02B25/00
Filed: 1980-09-15
Abstract: An adjustable eyepiece for an optical instrument, such as a microscope, in which two cylindrical parts of the eyepiece body have to slide coaxially has the sliding surface interface lined with a sleeve or self-lubricating material. Specifically, claims use of sleeves of PTFE or a thermoplastic polyacetal, though text states that high density polyethylene or polyamide-11 or 12, opt. filled with graphite, or MoS2 also suitable. Used in preference to grease, to eliminate risk of contamination of other parts of the instrument and also variations in the degree of grip with changes in ambient temps. Pref. the sleeve is made from a panel of matl. cut from sheet and machined or polished as necessary to attain the required degree of grip, typically a clearance of about 0.01 mm. Can be applied to existing eyepiece bodies, by relieving one of the body components sufficiently to accept a sleeve. The eyepiece bodies may be slotted and pinned for helical control of relative axial movement.

Title: Wine container with carrying handle - has resilient inner envelope protected by casing with removable dispensing valve and base plate
Inventor: DELWAULLE GILBERT
IPC: B65D8/06
Filed: 1980-10-09
Abstract: The bulk container for beverages, particularly wine, and which can be carried by hand, has a protectiVe outer casing (1) and an flexible inner envelope (21). As the contents are discharged, the envelope collapses so that air is excluded, preventing deterioration. The casing is stiffened by a grid of external ribs (25) and the top (33) has a flange ring (7) protecting a valve (24) for dispensing the contents. Further stiffening flanges (3,4) protect a folding handle, and a collar on top of the flexible envelope fits inside the flanged ring (7) from which the valve may be removed. After insertion of the envelope, a base plate (11) is inserted. This has projecting locking tongues (13) which fit into slots (5) in the outer casing so that it is not easily removed.
