Title: HF transistorised power generator - has two auxiliary circuits optimising output stage current and voltage swings by comparing with reference
Inventor: MEINKE HANS HEINRICH PROF DR
IPC: H03L5/02
Filed: 1977-02-15
Abstract: The HF power generator has its resonant load circuit coupled via an impedance transformer to the output of its amplifier. A first auxiliary circuit is used to set optimum voltage swing, and a second auxiliary circuit to set optimum current swing at the output stage transistors. The auxiliary circuits measure the voltage and current in the output stage and compare them with references. The result is used to initiate the adjustments. If changes are too fast for the auxiliary circuits to respond at the proper time, a protection circuit operates and reduces the excessive swing.

Title: Remote monitoring fault location system in cable TV network - short circuits line in case of fault and its DC loop resistance is reduced to given value
Inventor: PANKOW GUENTER ING GRAD
IPC: H04B17/40
Filed: 1977-02-17
Abstract: The cable network (1) branches off from a central station in several planes. In normal operation different marker frequencies are transmitted in the opposite direction back to the central station. Only terminal points in the top planes provided with amplifiers are also provided with different marker frequency generators. Each repeater in the distribution network nearer the central station is provided with a series resistor of the same value shunted by a capacitor for the marker frequency. A contact behind the resistor short-circuits the transmission line when the signal level drops or vanishes, or the distant supply disappears. In case of a fault these contacts prevent transmission back of the marker frequency and reduce the d.c. loop resistance of the faulty network branch to a value determined by its distance from the central station.

Patent DE-2805277-A1 (DE)
Title: Continuous casting of metals - in horizontal mould oscillating with casting ladle at specified speed relative to strand
Inventor: TUSCHY ECKHARD DR RER NAT
IPC: B22D11/053
Filed: 1978-02-08
Abstract: A continuous casting process for metals in cooled pass-through horizontal ingot moulds extracts the strand at a constant velocity but oscillates the mould along the longitudinal axis. The withdrawal speed is matched to the velocity of oscillation in such a way that the strand withdrawal speed equals the amplitude of the sinusoidal motion of the mould. This reduces the difference in the speeds to a minimum for a longer period. The resulting lower acceleration forces stresses the casting skin in the mould less severely and safeguards it against tearing. This eliminates longitudinal scoring and extends the life of the moulds. Even aluminium broze, Cu si Mn, Cu Mg etc. can now be cast continuously.

Title: Overhead travelling crane reeving mechanism - has return pulley detached from hook cage and attached between pulleys on carriage above
Inventor: GROSS HELMUT
IPC: B66D3/04
Filed: 1978-10-21
Abstract: The reeving system for an overhead travelling crane, converting it from a two strand to a four strand type, uses two swinging arms (23, 24) on the overhead carriage (4) to make an connection with the cage (8) supporting the hook (9). Then a central pulley (11) above the hook is separated from a plate (14) inside the cage, thus forming the two additional strands, as the lifting cable (7) is doubled around it. The pulley is mounted inside a carrier (13) with a hooked arm (19) projecting upwards. As the carrier is lifted, its sloping top (18) forces the swinging arms apart, assisted by two smaller arms (20, 21) on top, and the two hooked extensions (17) fit over spacer bars (25, 26) on the ends of the swinging arms. This connects the carrier and it pulley to the carriage, between the pulleys (5, 6) on the carriage, while the cable still passes around the pulleys (10, 12) on the cage.
