Title: Automatic telephone line asymmetrical signal balancing - using synthetic centre tap on power supply and regulation of supply transistors
Inventor: BOLUS DANIEL MICHEL AUGUSTE FE
IPC: H04M19/00
Filed: 1978-11-22
Abstract: The power supply, earth and -V, are connected to the lines (L, L') through complementary transistors (T, T') acting as constant current sources. A voltage divider (R3, R3') across the lines forms a centre tap whose voltage is applied to an operational amplifier (A). A symmetrical divider (R1, R1', R2, R2') across the power supply has its centre point (M) connected to the amplifier output. For d.c. on the lines the transistor units (D, D') act as constant current sources, and the potential at the centre point (P) of the line divider (R3, R3') is -V/2. If a symmetrical a.c. voltage is superimposed the centre point voltage is zero, the constant current feature is maintained, and the transistors have a high impedance to speech signals. For unbalanced a.c. superposition the amplifiers produce a corresponding output. The emitter voltage follows the collector voltage and the unsymmetrical signals are damped.

Title: Delayed photographic shutter release mechanism - includes monostable circuits determining time delay before operation of motor linked mechanically to shutter release
IPC: G03B17/38
Filed: 1979-02-16
Abstract: The delayed shutter release mechanism includes a first monostable circuit providing one of three possible time delays 10, 20 or 30 seconds. This controls an oscillator which provides a light and/or sound signal via a relay. At the end of the time the circuit starts a second monostable circuit with a period of 3 seconds. At the end of this interval a third monostable is operated for a period varying from hundreds of milliseconds to 6.8 seconds. During this time the shutter is opened. The electronic circuit cooperates with a motor (14) provided with a reduction gear. This pulls a wire (15) connected to a spring lever (16) turning about a pivot (17). The other end of the pivoted lever operates a push-button (22) on the end of a cable release (20). The monostable circuits may form two IC's.

Inventor: DIENER HERMANN
IPC: B05C17/00
Filed: 1979-06-12
Abstract: The gun has an attachment part in the form of a bayonet base (4) into which can be inserted the rear end of the cartridge (10) having corresponding lugs on its outside. The bayonet base is arranged in one (1) of two gripping levers (1, 2) which are connected to one another via an elastic region (3). A pressure rod (5) with a plunger (6) has projections (7) which are engaged with a rigid catch (8) on the one pressure lever (2) and an elastic retention (9) mounted on the other pressure lever (2).

Title: Igniter plug for grenade has rotary component - interrupting pyrotechnic chain in safety position and retarding device liberating rotary component and striker after predetermined time
Inventor: BOUCARD JEAN
IPC: F42C15/188
Filed: 1979-09-17
Abstract: An igniter plug for a grenade comprises a pyrotechnic chain consisting of a priming, a prim. charge and a sec. charge, interrupted inthe safety position by a rotary component and including a mechanical retarding device. A mobile piece integral with the mechanical retarding device holds the rotary component and the striker in the safety position and liberates the rotary component, then the striker, at the end of a predetermined time after the liberation of the stirrup, allowing alignment of the chain then the percussion. If the retarding charge is faulty, e.g. combustion is too rapid, the prim. charge is not initiated because it is aligned after the end of combustion of the retarding charge and the grenade does not explode. If the combustion is too slow, the prim. charge aligned before the end of combustion of the retarding charge is initiated only after too long a time. Grenades in which percussion is produced only on impact on an objective cannot be used in all throwing conditions. Percussion of the priming takes place in the ignited plug immediately after alignment of the chain, after passage of a predetermined time from the ejection of the stirrup. Safety of the delay is ensured by the mechanical retarding device and is not subject to a retarding charge which may vary in the period of combustion, partic. because of storage conditions. Percussion at the end of a predetermined time allows the retarding charge to be eliminated. Operation is assured in all cases at the end of the predetermined time, not necessitating impact on the objective.
