Title: Model railway switch point position indicator - has plunger selectively drawn into double coil arrangement linked via triple-wire connection to monitor circuit
Inventor: LANGHOF BERND
IPC: A63H19/32
Filed: 1979-11-20
Abstract: A plunger is drawn into one or other of two coils, energised as required. Three wires connect these coils to a monitor circuit giving visual indication of the instant switch position. Each coil is connected to an oscillator circuit consisting of a transistor (T1) a tuning capacitor (C11), decoupling capacitors (C13,C14) and rectifier diodes (D13,D14) working into a load resistor (R15). The output voltages across the load resistors (R15,R25) of the two circuits reflect the oscillation amplitudes across the two magnetic coils induced by the oscillators. The absorption of energy in the coil containing the solenoid plunger results in difference output values. These are compared in a comparator (ICI) and a high or low output determines whether a red (rt) or (gn) light emitting diode is on. In sophisticated systems, the output is fed into a status reporting and security control circuit via another transistor (T4).

Title: Tension relief on cable to lamp unit - by trapping it between lamp assembly and lamp unit housing
Inventor: FUHRMANN WALTER
IPC: F21V17/00
Filed: 1980-06-11
Abstract: The proposed lamp unit is typically intended for pedal cycles and similar applications. Tensile loads on the connecting cable are prevented from damaging or breaking the connection to the lamp. The required cable clamp is produced by trapping the cable between two parts of the complete lamp assembly such that it cannot be pulled through, but is not itself damaged at the clamping points. For example, in an assembly comprising a housing (1) and a unit containing the bulb, reflector, lens and connections (2) the cable (10) is located by passing round two right-angled bends when the two parts (1,2) are brought together. These angles may be formed by the locating ring (9) of the lamp unit (2) pressing the cable into a slot in an appropriately formed projection (8) in the housing (1).
