Title: Projectile fuze, more particularly for anti-aircraft gun ammunition
IPC: F42C15/24
Filed: 1953-10-23
Abstract: 744,564. Projectile fuzes. SOC. PER AZIONI FRATELLI BORLETTI. Oct. 23, 1953 [Oct. 25, 1952], No. 29413/53. Class 9(1) A mechanical time and direct action fuze has a body 1 of light alloy externally threaded for insertion in the nose of a projectile and housing a clockwork mechanism M, a safety device S and a detonator assembly 3, 4 with a ball 5 obturating the flash passage. A graduated ring 6 is screwed on to the body 1 and above it is rotatably mounted an ogive 7 of light metal with a datum mark for setting the fuze. A key 8 fixed to the ogive is connected by pins 9 to the clockwork and shear wires 11 secure a sleeve 10 from which guide cylinders 12 extend into slots in the key. The percussion mechanism comprises a hammer 13 in contact with a, cylinder 14 adapted to operate a plunger 15 to actuate a lever 16 and plunger 17 attached by a member 18 to a striker 19. The clockwork mechanism M comprises an escapement for regulating a time bell 20 driven by a spring 21. During transport and handling, detonation is prevented by two pins 22 extending from a striker sleeve 23 to lock members 24, 25 bearing on the detonator housing 3. On firing the projectile, the sleeve 23 sets back due to inertia, compresses a spring 26 and engages with the capsule 3 thus freeing the members 24, 25. The lower member 25 moves outwards, its displacement being regulated by the mechanism S and the detonator capsule moves forward into contact with the locking member 24. The ball 5 then leaves its seating to free the flash passage. After a predetermined displacement of the member 25, e.g., corresponding to a travel of 100 metres of the projectile, the member 24 opens out, freeing the striker and detonator assembly. To set the fuze, the ogive 7 is rotated, simultaneously winding the spring 21 which is then held by a friction device. As the spring is wound, the time bell 20 is rotated through a corresponding angle, so that after a predetermined interval a centrifugal catch 27 moves to release a spring-loaded sleeve 28. On firing the projectile, the sleeve 10 sets back by inertia shearing the wires 11, the cylinders 12 moving along the guide slots until the sleeve becomes wedged locking the key 8 to the body 1. The released sleeve 28 is driven by its spring 29 against the striker 19, which then hits the detonator 4. Should the projectile hit a target before the set time has elapsed, a membrane 30 in the nose fractures, the hammer 13 is driven against the cylinder 14 shearing a retaining flange 31, so that the cylinder operates the plunger 15 to actuate the striker 19. Should the projectile impact laterally against a target, the detonator capsule moves forward against the striker due to momentum.

Title: Semi-automatic apparatus for expanding a pressure welded passageway panel
IPC: B21D53/04
Filed: 1956-09-26
Abstract: 792,097. Making heat-exchangers; stamping. REYNOLDS METALS CO. Sept. 26, 1956 [Dec. 9, 1955], No. 29439/56. Classes 83 (2) and 83 (4). In the manufacture of heat exchangers, apparatus for expanding the unbonded portions of a pressure welded panel into passageways, comprises an expansion fluid conduit adapted to be connected to said panel for transmitting an expansion fluid under pressure to said portions, expansion fluid pressure supply means therefor and limit means, responsive to a predetermined expansion pressure in said conduit, for releasing the pressure in said conduit. The panel 1 has unbonded portions 2 and a pressure fluid connector 4 communicating with said portions. The apparatus comprises an upper stationary die 5 having a flat die face 6 and a lower movable die 7 provided with a fluid pressure holding chamber 9 surrounded by a sealing ring 11. The lower die is operated by an hydraulic jack 12. In operation, a pushbutton 23 energizes a solenoid 20 to close a valve 19 and enable a pump 17 to supply pressure fluid to the jack 12 and so close the dies. The closure of the dies is used to initiate the supply of holding pressure by energizing a solenoid valve 33 by a switch 37 to enable water from a supply 30 and compressed air from a booster accumulator 42 to be fed to the holding chamber 9. The panel expansion system is made responsive to a predetermined valve of panel holding pressure in the conduit 34 by a pressure switch 54 which energizes a solenoid valve 51 to connect the compressed air supply 40 through a booster accumulator 52 to the passageways in the panel. At a predetermined expansion pressure a switch 60 causes relay switches 26 and 27 to open, whereupon valve 19 releases pressure in the die-holding circuit and consequently opens pressure switch 37 to release the panel holding and expanding pressures. The differential between the holding and expansion pressures is between 2,000 to 3,000 p.s.i.

Abstract: 738,897. Electric recording systems. TELEFON FABRIK AUTOMATIC AKTIESELSKAB. Nov. 25, 1952, No. 29873/52. Class 40 (1). [Also in Group XXXIX] A telephone subscriber's meter is arranged to control an electrical condition which in turn controls the making of a permanent record of the meter reading. As shown, Fig. 1, the meter controls a variable resistance 1 which is connected to the bridge 4. The diagonal current controls the position of the punch 6 which is operated by the magnet 7 to perforate the tape 9. In modifications the variable resistance is replaced by a variable inductance, Fig. 2 (not shown), or a variable condenser, Fig. 3 (not shown), the bridge being fed by A.C. In a further embodiment, Fig. 4, in which metering takes place according to the nature and duration of the call, continuous metering current causes mercury 16 to pass through a fine mesh screen 17 in contact with electrolyte contained in the lower vessel. The mercury in falling to the bottom of the vessel progressively shortcircuits a resistance 18 which controls the recording mechanism as before. An alarm contact 27 is provided to indicate when the meter must be reset. In a further modification of this type, the resistance is caused to vary by direct electrolytic deposition, Fig. 5 (not shown). In a further modification a resonant circuit is formed by an inductance and a capacity which are changed by the 1000s and 100s wheels of the meter respectively and means is provided for determining the resonant frequency.
