Title: Electronic flash gun for flash bulb synchronised camera - has internal delay circuit to synchronise flash with shutter
IPC: G03B15/05
Filed: 1975-03-19
Abstract: The electronic flash gun is fitted in place of conventional flash bulbs or flush cubes and is coupled to the camera by the same connections as the flash bulbs or flash cube. A resistor is connected across the discharge tube and its value is equal to that of a flash bulb, and the electronic flash gun signal is taken off the resistor by a diode; it is amplified before being used in the flash circuit. The electronic flash is delayed by an amount which ensures that the shutter is fully open when the flash is released. The system can be attached to conventional, mass produced cameras with only the flash bulb-/cube synchronisation.

Title: Mortar guide fin erection mechanism - has sleeve forced rearwards by explosion to swing fins by rack and pinion drive
Inventor: CREPIN ROGER
IPC: F42B10/20
Filed: 1976-09-24
Abstract: A projectile such a mortar has a set of fins (1) at the rear which are swung from a horizontal position along the casing (12) to a position at right angles to it. Each fin has a rounded end (2) with a hole through it for a bush (7) acting as a hinge pin, for attachment to a lug (11) projecting from a sleeve (8) around the rear end of the projectile casing. This rounded end has teeth (3) around it, which mesh with teeth (14) on the outside of the casing, the arc of teeth (3) on the fin passing through a slot in the sleeve. The sleeve is forced rearwards by the explosive charge causing its teeth to travel and rotate the fin to its erected position.

Patent FR-2350640-A1 (FR)
IPC: G05D16/06
Filed: 1977-05-03
Abstract: The pressure regulator has a closing element which is designed as a sealing body (51) for a double-seat valve (34, 46, 50) and has a tubular extension (52). The aim is to ensure that the sealing body (51) does not give rise to friction and wear on the control rod. The intention is to eliminate a danger area in the pressure regulator. In addition, the double-seat valve (34, 46, 50) is to be of very simple construction. This is achieved by virtue of the fact that the tubular extension (52) of the sealing body (51) is secured in a definite position on a sleeve (36) containing a duct and the lift of an outlet valve (48) of the double-seat valve (34, 46, 50) is provided by a certain axial flexibility of the tubular extension (52).
