Title: Telephone connection for bidirectional and two unidirectional lines - uses two coupled transistors with output provided via transformer to ensure convergence
Inventor: DILY CLAUDE LE
IPC: H04B1/58
Filed: 1976-04-16
Abstract: Convergence between a two way telephone line and two pairs of unidirectional lines insuring a first degree of weakening between the two pairs of lines and a lesser degree of weakening between the two way line and each of the two pairs of lines, is controlled by a pair of transistors (7) (12), and an emitting resistance (11). The pairs of one way wires are connected from (3) to (6). The two way wire is connected across terminals (1) and (2) at opposite ends of a transformer (21). The other winding of the transformer is connected between a terminal (16) connected via resistors (10, 15) to the emitters of the two transistors and the negative supply voltage (-V) via a further resistance (11).

Patent FR-2350923-A1 (FR)
Title: Machine tool control device - has potentiometer in bridge circuit to control stop positioning motor
IPC: B23Q15/24
Filed: 1976-05-13
Abstract: The regulating device consists of a stop (1), which can be moved longitudinally by a motor (3). The latter drives a gear wheel (4) rotating an endless screw (5) connected through a tapped nut attached to the stop. The desired position of the stop can be selected and this is automatically obtained by an electrical bridge circuit which drives the motor until the desired position is reached. On the same arm as the motor gear wheel is another gear (7) which meshes with another gear (8) connected to a potentiometer (P2). The voltage from the potentiometer is sensed by the electrical circuit which operates the motor until the voltage corresponds to the voltage arising from the desired position of the stop.

Title: High temperature reactor spherical elements identified - by inductive receiver and bridge circuit to measure detuning and phase displacement
IPC: G21C17/10
Filed: 1976-07-16
Abstract: A method of detecting articles of electrically conducting material, pref. spherical fuel elements, moderator elements and absorber elements of a high temperature reactor, makes use of an inductive receiver through which the spherical elements each pass individually; a bridge circuit is connected to the receiver and the amplitude of the bridge detuning is evaluated, to give a signal. In addition to the evaluation of the amplitude, the phase displacement to the bridge supply voltage which occurs during the bridge detuning is utilised for detecting the individual elements. The bridge circuit is pref. operated with a carrier frequency in the range 50 kHz-1 MHz. The temp. existing at the measuring point has practically no influence upon the indicator signals obtained. Either a column of spheres or each individual sphere may be detected.

Title: Protective cutout for induction heater - has fuse which melts and releases spring loaded member to operate disconnector
Inventor: HANS LOUIS
IPC: H01H37/76
Filed: 1976-09-10
Abstract: The protective cutout, for an induction heater is not affected by parasitic induced currents, and is triggered by unacceptable increases in temp. at the surface of the induction head. The cutout consists of a disconnector triggered by a part that is set in motion as the fusible element in the cutout melts. The thermal fuse is located on the inside of a metal support made of a good thermal conductor. A helical spring is located between the support and the moving part. When the fuse melts, the spring drives the moving part against the disconnector's operating member.

Title: Bottle feeder for washing machine - has motor-driven table with bottle path controlled by pneumatic ram operated bars (PT 7.12.77)
IPC: B08B9/42
Filed: 1977-01-04
Abstract: The machine feeds bottles into and withdraws them from a rotary washing machine. It comprises a table (17) driven by a motor and equipped with conveyor chains (12) and guides for the bottles. A bar mechanism, with bars curved at the top, is moved to and fro by a pneumatic ram, so that the passage for bottles to be washed is opened and shut, thus synchronising their placement in the racks. This allows the rings to descent onto them which transport them to the washing machine. The motor can be arranged to stop when the support (5B) moves from an upper position (A1) to a lower one (A2), while the rings leave the bottles clean on the chains. It restarts when a second support starts to turn through 180 deg., so that the bottles remain standing.
