Title: Improvements in or relating to a percussion fuze for a rocket
IPC: F42C15/22
Filed: 1961-08-02
Abstract: 946,489. Ammunition fuzes. ETAT FRANCAIS. Aug. 2, 1961 [Aug. 8, 1960], No. 28103/61. Heading F3A. A direct action percussion fuze for a rocket, in which arming is brought about by acceleration, has a striker 1 engaging, during transport and prior to arming, a blind bore in a primer carrier 4 urged transversely by a spring 4b but immobilized by a pin 4a secured by a lock 5. The lock 5 has a bayonet slot engaging by its narrow end the pin 4a when in the locking position. A second slot in the lock engages a bolt 8b, the head 8 of which co-operates with a spring-supported sleeve 7 preventing the escape of balls 6 which lock the striker. When the fuze is at safe, the front end 1c of a recess in the striker head 1a abuts a stop 1b and is seen retracted within a transparent nosepiece 2. Before launching the lock 5 is moved manually to free pin 4a and bolt 8b, movement of these parts then being prevented by the launching tube. During acceleration in the launcher, the sleeve 7 sets back due to inertia, but is prevented by the bolt head 8 from moving far enough to free the balls 6, so that the striker remains locked and should the rocket become jammed in the launcher the spring 7a will return the sleeve to its forward position. When the rocket leaves the launcher, the bolt 8b moves outwards under the pressure of the sleeve 7 and the pull of the spring 8a. The balls 6 escape and free the striker, so that as the rocket decelerates the sleeve 7 and striker 1 are moved forward together and release the primer carrier 4, which then slides to the armed position bringing the primer 3 into alignment with the striker and a relay to the warhead.

Title: Improvements in and relating to apparatus for closing collapsible tubes
IPC: B65B7/14
Filed: 1931-10-15
Abstract: 391,207. Collapsable tubes or containers. DAY, W. H., Novelty Works, Ivy Road, Hounslow, Middlesex. Oct. 15, 1931, No. 28698. [Class 11.] An apparatus for securing the closed and folded over end of a collapsable tube without the use of clips comprises means for deforming the folded-over part, either by turning over the corners or by corrugating the folded part. Two composite plates 1, 2, as shown in the Figure, moving in slides 5, 8, are reciprocated towards and away from each other by cam action. First they are moved bodily together clamping the folded-over portion of the tube between them. Secondly the grooved member 3 of plate 1 moves forward, sliding over the bevelled member 6 of plate 2 and turning down the corners of the tube, along an angle to the fold and into a plane perpendicular to the folded portion. The member 3 then moves back to its former position and the member 6 moves back, leaving the tube clamped between the members 4, 7. Cam-operated jaws (not shown) now move between the plates 1, 2 in the plane of the folded part and turn the corners further down into the plane of the folded part. Finally the member 6 moves forward again and nips the folded-over corners firmly into the folded portion, and the member 7 moves forward slightly, thus embossing a number or other mark on the tube by the interchangeable die 22 in the member 4. For corrugating the folded-over part the compound,plates 1, 2 may be replaced by simple plates with serrated edges. The serrations are arranged to leave the extreme end of the tube uncorrugated or to make the corrugation shallower towards that end.
