Title: Vehicle transport and dropping pallet - has harder cushions under wheels than that under belly
Inventor: KRAMER VOLKER
IPC: B65D19/44
Filed: 1973-11-27
Abstract: The pallet is partic. for tracked vehicles parachuted down from aircraft. Where the tracks bear on it a cushion is provided, of high resistance to compression, whereas under the vehicle belly there is a further cushion of damping material having less resistance to compression, and extending right up to the belly. The damping material can be covered by a rigid plate to give even load distribution. The material under the tracks can be so arranged that after partial initial absorption of the load by the chassis, further absorption by the cushion takes place. The belly cushion can be of material slowly resuming its shape, so as to leave a free space between it and the belly when the vehicle bounces upwards.

Title: Cable crane with maintenance of cable pressure - has counterweight staying in locked position unless there is cable expansion
Inventor: WILCKEN WALTER
IPC: B66C11/18
Filed: 1974-03-04
Abstract: Cable crane, with a device to generate a given cable tension, with a drive plate and deflector rollers, a cable crab and a counter-weight where there is only one small given counterweight according to the position of the crab necessary for the travel cable, and this counterweight creates the drivability of the drive disc. The counterweight is checked for every other relatively unnecessary crab position by a locking device on the rise. When there is a maximum given movement path of the crab between two limit positions, the counterweight remains in the locked position and drops into a lower position automatically only on cable expansion so that the minimum necessary cable tension is maintained.

Title: Road tanker discharge arrangement - return line incorporates evaporator connected to high pressure side of discharge pump
Inventor: WOTHE KLAUS
IPC: F17C9/00
Filed: 1974-04-18
Abstract: The method of discharging a road tanker filled with a low boiling point gas, uses a fixed pump at the discharge station, connected to the return compression via a discharge valve, which pumps the charge through a relief valve and further shut-off valves, into the receiving vessel. Between the relief valve and shut-off valve is connected a discharge valve and an evaporator connected through the pressure compressor to the return line of the road tanker. This provides a constant pressure in the entire system, corresponding to the suction pressure of the pump, as well as a net positive suction head, preventing cavitation in the pump.
Patent DE-2422292-A1 (DE)
Title: Zero current state of converter - is generated with controllable main rectifiers in three-phase bridge connected to load
Inventor: LABER HANS DIPL ING
IPC: G05F1/10
Filed: 1974-05-08
Abstract: During normal operation firing pulses with a duration of over 60 electrical degrees are passed to the main rectifiers. The converter receives at first a command signal to reduce the current to zero and subsequently the firing pulses for the main rectifiers are shifted in the direction of the highest inverter supply. A zero current message is formed which introduces further measures in particular the quenching of the firing pulses for the main rectifiers. At the earliest value of the command signal for reducing the current, the duration of the firing pulses for the main rectifiers is reduced to a value under 60 electrical degrees.

Title: Vehicle fast response servo steering - feedback for wheel reaction and fail safe emergency manual steering
Inventor: CHRIST HUBERTUS DR ING
IPC: B62D6/00
Filed: 1974-08-20
Abstract: The servo assisted steering has a control valve which operates the servo motors in either direction. Special servo motors on the wheels are directly coupled to a reaction force generator acting on the steering wheel to provide the steering reaction force. The system is arranged so that road vibrations etc. are transmitted to the steering wheel via the reaction system so that the driver can feel a positive steering action, without any time delay between the road vibrations and the steering reaction. The system is also fitted with a failsafe steering which provides a mechanical coupling to the wheels if the hydraulic servo fails, in this case the reaction servos are inhibited.

Title: Peak amplitude increment of alternating current - has method for detection and avaluation of increments between two consecutive half waves
Inventor: PUTZ REINHOLD DIPL ING DR ING
IPC: H02H1/04
Filed: 1974-09-28
Abstract: The half-waves are of the same polarity, and a capacitor is charged during each positive half-wave, and another of the same capacitance during each negative half-wave by a voltage proportional to the current, and charge currents of both capacitors are combined in a wire. In case of charge current surges appearing, e.g. in case of a short-circuit, the first capacitor is used for control of an allocated monostable flip-flop (K), thus operating without delay a make contact (a), which prepares the way for a second charge current surge during the following, opposite polarity charging current surge, so that only this surge is used as a measure for current increment.

Title: Circuitry measuring extra excitation requirement - of sticking relay contacts for mechanically unconnected relay contacts in telephone exchange
Inventor: SCHOELER ULRICH
IPC: G01R31/327
Filed: 1974-10-24
Abstract: For every contact (x2) to be measured there are two gate circuits (F3, F4), each of which is used to charge an analogue memory (C3, C4) with a definite current (22) up to the working point of the contact.
