Title: Breech block for firearm firing caseless ammunition - has circular collar engaging annular groove in barrel for sealing during firing
IPC: F41A3/74
Filed: 1973-05-24
Abstract: The seal between the breech block and barrel end ensures that the gases generated on firing caseless ammunition do not escape. The seals have also a long life.

Title: Winch control system - detects load over particular stretch to determine maximum load before cutting out
Inventor: GREVE ERNST
IPC: B66D1/46
Filed: 1973-07-13
Abstract: The system is particularly for a winch lifting suspended deck sections, initially only the lowest one, then the next one up and so on, so that the load increases in stages. The load detected over a particular lifting height is used to determine maximum load, and when this is exceeded the lifting motion of the winch is automatically switched off. The winch drive can be changed over to a lower speed when the load exceeds a preset value. A separate safe load can be set for each stretch over which a load is lifted. Change-over to a slower speed can be arranged to take place only after an idler period determined by a time delay.
