Title: Improvements in or relating to a fuze for a missile to be fired by a gun with rifled bore
IPC: F42C15/26
Filed: 1966-03-03
Abstract: 1,114,063. Projectile fuzes. MEFINA S.A. 3 March, 1966 [2 April, 1965], No. 9302/66. Heading F3A. A fuze for a projectile to be fired from a gun with a rifled bore comprises a support 7 adapted to move transversely under centrifugal force to align a detonator 6 with a striker 4, and a clockwork safety system operating during flight and adapted to keep the striker 4 away from the detonator 6 during a predetermined period following the firing of the projectile. The clockwork safety system comprises an escapement wheel 20 driven by a toothed sector 21 pivoting round a spindle 22. The toothed sector meshes with a pinion 24 coaxially rigid with the escapement wheel 20 and is driven under the action of centrifugal force by an eccentric mass 23, Fig. 6. The toothed sector is provided with a conical recess 35 in which rests a conical collar 5 provided on the striker 4, and an arcuate slot 27 through which the portion of the striker below the collar 5 passes. A spring 28 acting through a socket 29 holds collar 5 in the recess, thereby preventing angular movement of the sector and axial movement of the striker. As soon as the projectile is fired a spring loaded plunger piston 11 collapses within its cylinder 12 in the detonator carrier 7, and the extension 14 of the plunger is withdrawn from an opening 15 in a stationary plate 16 and an opening 18 in the balance wheel 19. The carrier 7 moves transversely under centrifugal force to align the detonator 6 and striker but the balance wheel is maintained stationary by engagement of the collar 5 of the striker in the recess 35 in the toothed sector. As soon as the projectile passes out of the gun the axial acceleration is cut out and the balls 32 roll along the surface 33 under centrifugal force to lift the socket 29 and free the toothed sector which rotates and eventually moves free of the shoulder 5 on the striker to leave the striker perfectly free to move axially. On striking the target a pusher rod 37 urges the striker against the detonator 6. If the projectile misses the target and as soon as the centrifugal force has been reduced sufficiently by the friction of the air, the spring 28 urges the socket 29 and balls 32 downwardly, simultaneously moving striker 4 against detonator 6 to cause self destruction of the projectile.

Title: Method of and apparatus for exploration for subterranean potroliferous deposits
IPC: G01V9/00
Filed: 1962-03-12
Abstract: 997,831. Prospecting. ATLANTIC REFINING CO. March 12, 1962 [May 9, 1961], No. 9369/62. Drawings to Specification. Heading E1F. Subterranean petroliferous deposits underlying a body of water are detected by measuring at different locations, a property of the water itself which is affected by the leakage of gas from the deposit. As the gas bubbles through the water it lifts the lower colder or salter water from the bottom to the surface so that the most usual properties measured are surface temperature or electrical resistivity. Infra-red heat sensitive equipment, a location indicator and a recorder are flown over the water to record the variations in temperature of the waters surface. The location of variations are then verified by the same apparatus or by sampling the water. The apparatus for measuring resistivity may be water borne, or in the case of an area covered by stream, it may be land borne.

Filed: 1949-04-06
Abstract: 677,070. Tape dispensers. SESSIONS, Ltd., W., and PHILIPSON, A. L. April 4, 1950 [April 6, 1949; Dec. 1, 1949], Nos. 9392/49 and 30869/49. Class 18 Backing tape having labels adhesively secured thereto is bent round a sharp edge as it is fed from the container holding a roll of the tape, so that the labels peel off from the tape. Guide members are disposed one above and the other below the top wall of the container adjacent the front edge so as to provide guide ways between themselves and the top wall, for the tape, the labels as they peel off from the tape being delivered over the guide member above the top wall. In one embodiment, a roll of tape with labels secured thereto is housed in a cardboard box 10 having a closure 11 which slidably fits over the open end of the box 10. A projection 14 extends from the front wall of the closure 11 into the box and provides the guide for the tape passing between it and the top wall 21 of the box. As the tape is withdrawn it is sharply reversed on itself around the front edge 19 of the top wall 21 and extends beneath a flap 17 which extends from one wall of the closure across the top of the box and is secured to the opposite wall of the closure, thereby providing the guide member above the top wall 21 of the box. As the tape is withdrawn the labels peel off from it above the flap 17 due to its sudden reversal about the edge 19. The edge 19 may be reinforced by a metal strip 20 bent about it and extending within the box where its opposite end is secured by bending it around the edge of the lower wall 22 of the box. Alternatively the closure may be formed integral with the box being an upturned wall extending from the bottom wall 22. In another embodiment the device comprises a metal holder containing a roll of the tape with the labels affixed thereto and having side walls 32 between which a roller 35 for receiving the backing tape is mounted. The tape is withdrawn by rotating the roller 35, and passes between a guide 37, secured to the detachable front wall 36 of the holder, and the top wall 34, sharply around the front edge of the top wall and beneath a guide 42 positioned above the top wall to the take up roller 35. The leading edge of the guide 42 is upturned to deflect the labels as they peel off from the tape and the guide itself is pivoted to the holder by pins 43 engaging brackets 44 extending downwardly from the ends of the guide 42. An inwardly turned flange 47 is provided on the brackets and serves to retain the front wall 36 in position. If desired the front edge of the device may be curved laterally to add rigidity to the labels as they peel off from the tape. Alternatively the roller 35 may be mounted within the holder so that the tape is drawn into the holder for removal of the labels. Heating means may be provided for assisting in the removal of the labels.

Title: Improvements in or relating to Signal Receivers
IPC: G08B3/10
Filed: 1968-02-28
Abstract: 1,166,970. Selective signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 Feb., 1968 [2 March, 1967], No. 9629/68. Heading G4H. In a selective receiver, a frequency detection circuit comprises a gate 6 enabled by a time gate signal which starts after a signal denoting the beginning of a period of an incoming frequency and ends after a signal denoting the end of a period of a selected incoming frequency, the latter signal being applied as the second input to the gate 6 to set bi-stable 20 connected to integrator 23 and threshold device 24. The first trailing edge output of frequency divider 5 resets bi-stable 11 to remove the blocking input on counter 8, which after a delay produces output G1a. Gate 13 passes G1a to set bi-stable 7 and start the first time gate. If divider 5 produces no leading edge signal within the time gate G1a-G1b, G1b resets 7 which in turn sets 11 and resets counter 8. If a leading edge signal from divider 5 occurs in time gate G1a-G1b, bi-stable 20 is set, remaining set until the next trailing edge signal from divider 5 and counter 8 is reset. Under these conditions corresponding to the detection of frequency f 1 , threshold device 24 eventually produces an output pulse to trigger monostable 25 and enable gate 27 for the next calling signal interval. Detection of subsequent frequencies f 3 , f 2  is similar, final trigger 29 which is bistable, lighting lamp 2 when the entire sequence of frequencies corresponding to the receiver has been received. In another embodiment, Fig. 3 (not shown), the time gate signals G1a-G1b &c. are applied to separate bi-stables 7 controlling separate gates 6 connected to individual integrator/ threshold device circuits. The output of the second and third circuit is gated by a trigger in the preceding circuit. This arrangement can also be used to receive a combination code of the first two selection frequencies after reception of the selection sequence.
