Title: Improvements in and relating to fuses for projectiles and the like
IPC: F42C1/02
Filed: 1924-07-25
Abstract: 239,876. Pantoflicek, B. July 26, 1923, [Convention date]. Projectile fuzes. - Direct-impact percusssion fuzes are made with a firing member adapted to be moved into or kept in line with and driven against a second firing member on impact. In Fig. 1 the plunger 3 is driven in by direct impact while the firing pin 2, normally held at one side, as shown, by a spring 6, is swung by its momentum into line with the percussion cap 1, against which it is driven by the plunger 3. The firing pin may be variously constructed and mounted relatively to the plunger. In Fig. 5, the firing pin 2 is released by a momentum pellet 11 and is driven against the percussion cap 1 by the plunger 3 while swinging into line therewith. In Fig. 13, the firing pin 2 is moved into line with the percussion cap 1 by the transverse slide i, which is wedged in by the inward movement of the plunger 3; the momentum of the firing pin 2 then drives it against the cap 1, which is being driven back with the plunger 3. In a modification of this, the firing pin is slidable in a member pivoted to the plunger and rocked about its pivot when the plunger is driven in, whereby the firing pin is brought into line with the percussion cap carried by the plunger. In another modification, the firing pin is hinged to the plunger and is thrust laterally inwards by a shoulder on the fuze body to become aligned with the percussion cap by the inward movement of the plunger. In another modification, the firing pin is a spring secured to the plunger and normally laterally stayed in alignment with the percussion cap. When the plunger is driven in, the firing pin is released from its lateral restraint and moves out of alignment with the cap unless the plunger is driven in at a sufficient speed, as occurs on impact. In other modifications, the firing pin or the percussion cap is mounted to slide transversely or obliquely and is moved by momentum action or by centrifugal force or by the action of the inwardly moving plunger.

Abstract: 756,547. Magnetic sound recording and reproducing apparatus. PHIDELITY MAGNETIC PRODUCTS Ltd., and GOULD, K. G. Jan. 11, 1954 [Oct. 9, 1952], No. 22955/52. Class 40(2) Sound, particularly from a telephone, is recorded on one of several magnetic wires or tapes 11 each mounted in a tray C, arranged to slide in a cabinet which may hold 40 trays. The driving, recording and reproducing operations are effected by remote control from any of several stations. On inward movement of a tray, initiated by remote control, a clutch 23 is engaged to drive a turntable 10 carrying an endless tape 11, and the tape engages a recording head R. Movement of a solenoidoperated rod 18 causes either of rollers P<SP>1</SP>, P<SP>2</SP> to engage a corresponding capstan roller D<SP>1</SP> or D<SP>2</SP> to drive the tape for recording or reproduction or to rewind it. In a modification, two spools may be used, the rewinding being faster than the forward drive. Where one spool is used, the tape may be driven at a fast forward speed to return it to its starting position or it may be rewound by folding it in a lidded box with inlet and outlet slots. Each tape may be driven at a fast forward speed has a slot 17 to allow the head to engage the tape, which slot may have a spring- urged cover that is slid open by a projection when the tray is moved into recording position. Controls may be provided, e.g. in a telephone instrument, so that a message can be recorded and if necessary the record rewound, for a short distance to edit it or to wholly reproduce it. Establishment of connection to a record may be indicated by a signal. The usual "ringing" and "engaged" tones may also be incorporated. A compartment containing a recorded tape may be indicated by e.g. a light.
