Title: Continuous measurement of pH of aqueous solution - uses preamplifier in immediate vicinity of electrodes incorporating integrated operational amplifier
Inventor: LAURANS CLAUDE
IPC: G01N27/416
Filed: 1974-10-04
Abstract: Continuous measurement of the pH of an aqu. soln. is performed by a device incorporating a pair of electrodes (V) and (R) immersed in the soln. and connected to a preamplifier (A1) which is in the immediate vicinity. A cable (c) interconnects the preamp with a further amplifier (A2) which drives a galvanometer (g) calibrated directly in pH. Amplifier (A1) receives low tension A.C. over conductors (1) and (2) which drives an integrated operational amplifier serially connected to a magnetic amplifier which ensures isolation between input and output of the preamp. The low tension input to preamp (A 1) enters a three winding transformer the output of which is full wave rectified to provide the requisite DC drive currents to the operational and magnetic amplifiers. The amplifier (A2) may feed a data logging device or a system control unit in a feedback system and also comprises an operational amplification stage.

Title: Frequency synchronising system for oscillating timepiece balance - by combining signal train with balance oscillation signal
IPC: G04C11/08
Filed: 1974-11-26
Abstract: The electronic synchronising signal is used to synchronise an oscillating timepiece balance with a given frequency. The actual frequency of the oscillating balance is measured as a function of the amplitude of the oscillations, the signal representing the balance oscillations combined with a recurrent wave train at the given frequency. The amplitude of the composite signal obtd, is compared with a threshold value, so as to provide a control signal, when the composite signal exceeds the threshold value. The oscillations of the timepiece balance are corrected by using the control signal to adjust the amplitude of the oscillations.

Title: Increased depth of focus and resolution in light microscopes - images any object planes with powerful magnifications
IPC: G02B27/42
Filed: 1974-10-16
Abstract: The image of an object is scanned point-by-point by means of a single-or multi-hole scanning diaphragm, which lies in a plane conjugated to the plane onto which the objective is focussed. The scanning diaphragm also scans the surface area of the object by means of a light spot pattern. The scanning of the object image and/or the object takes place in a direction (X and/or Y direction) parallel to the focussed plane, alternatively vertical to the focussed plane (Z direction). Scanning in the Z direction is by means of a periodic displacements of the object and/or the objective.

Title: Tape recorded data sequence marking system - operates over high range of tape speeds in either direction using digital signals
IPC: G11B27/00
Filed: 1976-04-09
Abstract: The system is for marking sequences of data inscribed on a first track of a magnetic tape. This tape passes through a tape reader which has at least two magnetic reading heads. The first reading head reads the first track. The second reading head reads a second track on which is inscribed, in binary code, groups of digital signals. These groups of signals tape position reference marks. Each group of digital signals forms a position word. This word characterises the section of tape on which it is written. Each group of signals also contains a synchronising word which is identical for all the groups. The system has a first digital circuit connected to the second reading head. This circuit identifies the reading configuration of the synchronising word, which is dissymmetric.
Patent FR-2313527-A1 (FR)
IPC: E05B65/44
Filed: 1976-05-12
Abstract: The bottom (2) of the lock case (1) receiving the bolt (5) has at least one trough-shaped recess (3), in which a ball (4) is arranged to half its depth and displaceably along the recess (3). The bolt (5) is provided with two mutually identical perforations (6, 6'), of which each receives one half of the ball (4), one in the open position and the other in the closed position, and thereby blocks the bolt (5). On turning the key, the key bit (10) presses the ball (4) out of the perforation (6, 6'), so that the bolt (5) is released and can be brought into the other position by the key bit (10). In this other position, the ball (4) falls automatically into the other perforation (6', 6) and once again blocks the bolt (5). If recesses (3) and perforations (6, 6') are arranged on both sides symmetrically relative to the transverse axis of the housing, the lock can be used as a reversible lock. An oblique position of the recesses (3) relative to the longitudinal axis of the housing allows the ball (4) to fall back even when the lock is fitted horizontally to a drawer. This blocking means avoids brittle and therefore fragile springs and, moreover, is space-saving.

The rotating commutator segments are mounted on the end face of the rotor assembly and the brushes press in an axial direction against them. Each brush consists of a broad radial arm (60) with a contact button at its free end resting against the commutator end contact faces. The other end of each brush is fixed to a support ring mounted to the end cap of the motor. Angular displacement of the brushes is prevented by a point and notch arrangement.

The connection comprises a lockable hinge with a bolt (5) forming an axle (52) uniting a tapered handle-end-socket (1) to a head-plate (2) and the socket (1), and locking is effected by the bolt acting with grooved cantilever-interfaces (4',3'). The cantilevers (4,3) may each incorporate a ring with the axes respectively parallel and normal to the head plate (1). The long axis of the socket, and the abutting ring-faces may include radial 'V' grooves. The ring (4) may have a square axial hole which engages a bolt shoulder (5') to lock it against rotation.

Title: Constant velocity joint for front wheel drive vehicle - has meshing gear teeth cut in surface of spherical ends of shafts
IPC: F16D3/18
Filed: 1977-01-28
Abstract: The driving and driven shafts of a constant velocity joint have spherical ends. Gear teeth are cut in these spherical surfaces and the spherical ends are supported in spherical bearings in a common housing, so that the teeth of the two spheres are in mesh. The spherical bearings enable the angle of intersection of the two shafts to be varied but the driven shaft always runs at exactly the same speed as the drive shaft. The constant velocity joint is particularly suitable for the front wheel drive of automobiles, but it can be used in machine tools and agricultural machinery.

Title: Transparent bottle inspection system - employs electronic circuit to differentiate between shadows and foreign bodies
Inventor: FAANI SIAMAC
IPC: G01N33/00
Filed: 1977-02-10
Abstract: High speed inspection of bottles used in the food and drink industry is performed using an electronic system to detect opaque foreign bodies. Problems of differentiating between shadows and these bodies are overcome. Bottles (11) on a conveyor (10) are illuminated (13) from behind such that the image is projected onto photosensitive detectors (23). Synchronisation signals are provided by an optical system comprising source (18) and receiver (19). These signals are passed to a digital electronic circuit (24, 26) where rectilinear coordinates of an inspection window are superimposed on the detected image. The data in memories is used selectively per analysis of different physical characteristics of the bottles.
