Title: Surge suppressor for sections of railway overhead lines - has aerial acting as arc detector at spark gaps supplying control signals to substations
Inventor: HEROLD THOMAS DIPL ING
IPC: H02H1/00
Filed: 1978-11-17
Abstract: The surge suppressor is for particular sections of overhead transmission lines for railway networks. It comes into effect when there is an electric arc which extinguishes rapidly to prevent any of the usual damage. The disconnection gap (8) is monitored by a receiving aerial (9). It is installed on the pylon for the overhead line above the gap being monitored so that its main reception axis is inclined towards earth. The aerial acts as an arc detector and is used to transmit a cut-out signal to the substations or interconnecting stations. It is turned to the hf. components of the discharge arc and uses the amplitude of the criterion for the short cut-out of the supply. The aerial is directional.

Title: Optical data transmission system coupling element - has body with groove for optical fibre intersected by sloping mirror below junction
Inventor: WINZER GERHARD DR
IPC: G02B6/28
Filed: 1978-11-29
Abstract: The coupling element for an optical data transmission system has a transparent body with a groove along its surface for an optical fibre. At a junction point is a waveguide branch formed as a glass capillary containing the branch glass fibre at right angles to the grooved body. Between the end surface (40) of the branch and the body is a plane supporting surface formed by optical cement. Below this junction is a reflective surface at an angle of 45 deg., secured between portions of the body by a transparent adhesive. This must be transparent for the wavelength conveyed, and having the same refractive index as the optical fibre. In an alternative design the branch portion has a spherical end, and fits into a concave recess in the main body.

Patent DE-2933893-A1 (DE)
Inventor: HAMANN WALTER
IPC: G08B13/14
Filed: 1979-08-22
Abstract: An anti-theft system for the protection of a bag of papermoney or the like being transported from a bank safe to a waiting valuables transport vehicle, having a security apparatus for marking or otherwise making useless the papermoney or for giving an alarm in the case of attempted theft. At least one stationary transmitting unit is used for radiating radio waves along the path of transport for being received by a receiving unit on the money bag. The security apparatus is put into operation when the receiving unit no longer receives an agreed information pattern from the transmitting unit, which undergoes comparison with information regenerated at the same data rate from a shift register at the container. In one form of the system, the information to be transmitted and to undergo comparison is produced by the transmitting end and stored sequentially in solid-state memories at a high data rate at the transmitting and receiving ends of the system before each transport operation. Then, on transport, synchronized readout of the information from the memories takes place at a lower data rate for comparison, the security apparatus being put into operation if the transmitted signal is no longer received, this being sensed because of the effect on the comparison operation. In a further form of the system the memories are read only memories which may be exchanged for security purposes.
