Patent DE-2915236-A1 (DE)
Inventor: GERHARD THOMAS
IPC: B61B3/00
Filed: 1979-04-14
Abstract: A damped suspension system for conveyors which has a pair of shock absorbers each of which is associated with an initial stressed spring thereby exerting a balancing effect. In preferred embodiments the shock absorbers are provided with means comprising, for example, a casing and a sleeve wherein the cylinder is executing and up and down movement relative to the sleeve.

Patent DE-2932539-A1 (DE)
Title: Level and frequency testing circuit - uses operational amplifier with transistor in inverting input loop
Inventor: KUNA FRITZ
IPC: H04B3/46
Filed: 1979-08-09
Abstract: A reference voltage (UR) applied to the inverting input of an operational amplifier (OP) determines the min. response signal level required for a particular response signal for testing, e.g. a telephone transmission line. This signal (S) is applied to the non-inverting input. The base of a transistor (T) is placed into the return loop and remains conductive as long as the reference voltage is larger than the input signal in which case the amplifier output (A) is at the level of the lower supply voltage (U1). As soon as the input signal (S) rises above the reference voltage the transistor (T) is cut off, the inverted input voltage is lowered to the level of a second reference voltage (U3) which may be ground level, and the output (A) rises rapidly to the higher supply voltage (U3) and remains there. Only when the signal input is reduced to a level below the second reference voltage (U3) is the original output condition restored.

Title: Wind indicator type relay - has bowed plate with magnet at end keeping contacts made of broken by force or air stream
Inventor: RICHARZ FRANZ
IPC: G01P13/00
Filed: 1979-09-17
Abstract: The wind indicator relay is used as a mechanical-electric air current monitor. If the air current fails or falls too low, the protected installation is switched off or an alarm actuated. The making of the contacts (2) in the switch tube (1) takes place via a magnet (3). The latter (3) is attracted by another magnet (4) mounted on a plate (5) kept out of its normally bowed shape by the force of the air stream. Alternatively, the air pressure keeps the plate in its bowed condition and the contacts made, indicating that the air stream is at a min. strength. A breaking of the contacts releases an alarm and/or switch off. In either case, no ball-bearings are needed as is usually the case with the possibility of clogging up by dirt ingress.
