Title: Directional cassegrain microwave antenna - has stepped parabolic reflector or stepped secondary convex reflector to give sector radiation pattern
Inventor: REBHAN WOLFGANG DIPL ING
IPC: H01Q19/19
Filed: 1974-04-05
Abstract: The directional Cassegrain microwave antenna has a secondary radiator located at the focus of a stepped parabolic reflector to produce a sector-like radiation pattern. The secondary radiator consists of a concave reflector facing the primary radiator which radiates through a hole in the parabola along the axis of the latter. If the main reflector is stepped, then the secondary reflector is smooth. If the main reflector is smooth, then the second reflector is stepped. The advantage of the antenna lies in its giving a good approximation to a sector-like radiation pattern for very few components and low cost.

Title: AC variable output control - involves using thyristors which switch sequentially to produce pulses with a sinusoidal envelope but with variable mark to space ratio
Inventor: HENNING HANS PROF DR ING
IPC: H02M1/08
Filed: 1974-10-22
Abstract: A thyristor based variable AC source is derived from a constant amplitude AC source such as the mains. A commutative switching device is used and the circuit consists basically of two thyristors (1, 2) connected back to back at the output of a transformer (4a, 4b) fed typically from the mains. Auxiliary thyristors (9, 10, 11, 18, 19, 20) may be connected in parallel with the original thyristors to increase current output. The thyristors are switched in a repeated commutative sequence so that a pulse train with a sinusoidal envelope is produced, the mark to space ratio of which determines the output current from the network. The commutating pulses applied to the thyristor gates are produced by a control circuit.

Title: Baling press. with chain-driven pressing plate - has plate moving up from bottom position and also used to eject bale
Inventor: KAMPWERTH FRIEDRICH
IPC: B30B9/30
Filed: 1975-06-19
Abstract: A pressing plate moves from the bottom of the casing upward to press the material against the firmly closed lid, serving in this cas as an abutment. The upward movement is enforced by a drage chain driven via a suitable reducing gearing from an electric motor. The driving arrangement is fitted with an automatic tripping device cutting out the motor, once the required compactness of the material is reached. This is done by an electric overload relay. When the compacting is completed, lid is opened and by re-starting the motor, the bale is pushed out from the casing. For recharging the casing with new material the rotation of the motor is reversed and the pressing plate returns to its original position.
