Title: Use of multi-headed projectiles - with ejection of individual heads only when direct hit unlikely
Inventor: HELD MANFRED DIPL PHYS DR
IPC: F42B12/64
Filed: 1973-12-22
Abstract: Operational use of multi-headed shells with hollow charges includes a flight path on which the shell remains as a unit until a certain or high hit probability is obtd., so that all the independent heads act in common on the target. When a direct hit is no longer expected, with the undivided, shell, the individual heads are ejected before the target is reached and proceed further on their own paths. Preferably the appts. has a ground appts. with a rangefinder for the target range from the firing point, and with a difference calculator for the distance from the shell to the target. A goniometer determines the path deviation angle and a trigonometric calculator forms the actual deviation from the target line, and a second one establishes the deviation angle between the target line and the remaining flight path.

Patent DE-2400176-A1 (DE)
Title: Buffer with tube containing compressible cellular blocks - has two such blocks of different diameter, providing progressive buffer action
Inventor: SCHWARZ WILHELM DR ING
IPC: F16F1/37
Filed: 1974-01-03
Abstract: The buffer has a plunger adapted to compress the blocks which widen under compression and then resist movement of the plunger by frictional engagement with the wall of the tube. To avoid too rapid a rise in the friction forces and achieve a lengthening of the buffer stroke for a given load, the block remote from the plunger is made of lesser diameter than the block adjacent the plunger. On compression, the larger block, which may also be of lesser density, widens first while the other block does not widen until later so that the build-up of resistance is progressive.

Title: Automatic accident warning system for road vehicles - using sonic or optical transmissions from vehicles which are picked up by telephone line transducers
Inventor: LEPPER WILHELM DR ING
IPC: G08B25/00
Filed: 1974-08-14
Abstract: The automatic accident warning system is for use on roads and depends on a telephonic link. In the most straightforward case, where motorways are being monitored, the vehicles each contain a small sonic transmitter which on collision produces a sound at an emergency frequency, possibly ultrasonic. This carries over a fairly short distance to the next telephone point on the motorway, where a special transducer sends a signal to the nearest monitoring post. Optical signals are also possible. For situations other than on motorways, the public telephone system or even power supply system may be used to transmit emergency signals. The cost of suitable devices in the vehicles would be very low.
