IPC: H01J9/22
Filed: 1958-04-02
Abstract: A method of making a luminescent screen, for use in cathode-ray tubes, comprises the steps carried out within a high vacuum of slowly vaporizing zinc sulphide and an activator, e.g. manganese, condensing the vapours on a transparent refractory base to form a thin film and subjecting the film and base to baking at a temperature between 750 DEG  C. and 900 DEG  C. for a time, e.g. 5 to 15 minutes, sufficient to render the film crystalline, transparent and luminescent.  The zinc sulphide and the activator can be simultaneously and/or separately vaporised.  The transparent base can have a coefficient of thermal expansion close to that of zinc sulphide and can be of glass known as F-83.  The screen can be subjected to a further baking in air at about 500 DEG  C. for a short time.  Activators other than manganese referred to are silver or copper used in conjunction witha trivalent metal or with a halogen as co-activator.

Title: Fuse mechanism for projectiles
IPC: F42C15/188
Filed: 1974-10-29
Abstract: 1452370 Time fuzes for projectiles FORENADE FABRIKSVERKEN 29 Oct 1974 [9 Nov 1973] 46763/74 Heading F3A A time fuze for projectiles comprises: a striker 16 held against axial displacement by engagement of a neck portion within a slot 15 that is formed in a lock 14; a detonator 35 carried by a rotor 36; a ring 7 for setting the time delay, frictionally engaged by a cog ring 6; a follower 8 passing through a slot 9 in the ring 7 and into a recess 10 in a fuze cover 5; a releaser 13 for the follower; a spring 21 having a portion 24 which extends into and blocks a mechanical electronic, or electrical clockwork 25; and locking pistons 19, 30, 26, 38, 42. In the zero setting of the fuze, a head 32 of the piston 30 abuts the underside of a flange 34, extending from the ring 6, and lies below a recess 33 in the ring 7. To set the fuze the cover 5 is rotated, whereby the follower 8 rotates the ring 7 relative to the ring 6 thereby misaligning the recess 33 and the piston head 32 by an amount corresponding to the desired delay. During this movement, the piston 19 enters a recess in the ring 7 and is withdrawn from its locking position within an aperture 18 in the lock 14. If the projectile fitted with the fuze is now fired, the piston 26 sets back owing to its inertia and unblocks a piston 38 locking the rotor 36; and, at the same time, the piston 26 disengages the lock 14 which then moves until its shoulder 29 encounters the piston 30. The spring 21 moves with the lock 14 to unblock the clockwork 25, and disengagement of the retainer 13 from the lock allows the retainer 8 to be withdrawn from the recess 5 so that the rings 6 and 7 are simultaneously rotated by the clockwork. Rotation of the two rings enables the piston 42 to enter a recess 46 in the ring 6 thereby releasing the rotor 36 which swings the detonator 35 into alignment with the striker 16. As the rotation of the rings continues, the head 32 of the piston 30 progresses beyond the end of the flange 34 and eventually enters the recess 33, whereupon the piston 30 disengages the lock 14 for further movement to release the striker 16. In a modified fuze an additional impact function is provided by a rocker mechanism that releases the lock 14 for its final movement if the clockwork has failed to operate prior to impact. The rocker is actuated by a driven-in plunger; or by a piston that is thrown forwards on impact; or by a ball that is torn away from a magnet. If the fuze is to be used for spinning projectiles, the rotor 36 is additionally locked by a resilient tongue and/or a spring loaded plunger, both of which move outwardly under the action of centrifugal forces.
