Title: Asymmetrical branching unit for optical fibres - forms low-loss coupling necessary for light signal transmission of one or more users in light conducting fibre
Inventor: GUTTMANN JOACHIM
IPC: G02B6/28
Filed: 1980-02-15
Abstract: The method for asymmetrically branching optical fibres consists of using a specially shaped fibre (2) which is the customary circular cross section but has a V-shaped groove along its longitudinal axis, large enough to lay in a smaller diameter fibre (4 or 5). This smaller fibre (4) is curved into the groove so that the light signal is transmitted loss-free into another fibre (3) which is of the same diameter as the larger fibre with the groove (2), all three fibres meeting at a common coupling point (K2). If another smaller fibre (5) is curved into the groove towards the other end of the main fibre (2), so that light arriving from a third large fibre (1) at a common coupling point (K1) opposite to the other coupling point (K2) strikes it, a large portion of the otherwise wasted light output can be used as a reception signal.

Title: Safety circuit with several signal inputs for ammunition - uses two different criteria for safety circuit disarming in selectable timing sequence
Inventor: HELD MANFRED DIPL PHYS DR
IPC: F42C15/40
Filed: 1980-04-05
Abstract: The circuit is intended for firing a missile, or a mine. It has several signal inputs and its deblocking takes place, using two different criteria in a selectable time period, e.g. provided by a launching or separation contactless sensor. The used electrical pulse of launching is defined by one or several following criteria, i.e. a given amplitude within upper and lower limits, an adjustable minimum period, a selectable time period, and a given output impedance. The circuit has an input (1) for an activation starting signal, coupled via a filter (4) and an impedance converter (5) to a monoflop (8). The latter output is connected to an input of a logic element (9). A second signal input forms a contact sensor (10), signalling the launching of the missile. The sensor is connected to a second monoflop (12) via a series-connected amplifier (11). The monoflop output is connected to a second input of the logic element.

Patent DE-3021916-A1 (DE)
Title: Metering counter for remote read=out - is interrogated by reversing power supply and transmitting pulses to step register
Inventor: SAITO KAZUHITO
IPC: H04Q9/14
Filed: 1980-06-11
Abstract: Consumption of each unit of water, gas etc., at a remote station triggers a thyristor to discharge a capacitor and step a decade counter. Power for the counter is drawn via a diode from DC sent over a pair of wires from a control. To read the counter, the control reverses the DC, which activates a read circuit at the remote, via another diode. The control then transmits pulses which step a register from 0 to 9. When the register coincides with the 1000s position of the counter, an AND-gate draws a current pulse from the line, which is detected by the control. After 10 pulses, the remote steps the 01Dgatetothe100spositionandtheprocessisrepeated, similarly for the 10s and 1s positions. Then the control restores the supply to the original polarity.
