Abstract: 550,897. Fuzes for projectiles, bombs and the like. MIDGLEY, A. H. Sept. 15, 1941. No. 11800. [Class 9 (i)] Fuzes for projectiles, bombs and the like of the kind which are armed by the rotation of a vaned member, have the vanes of the arming device detachable so that rotation of the device ceases after arming. The striker c has a cylindrical guide portion working in a sleeve e and a screwed extension portion coacting with a nut f to which is attached a cap portion g. This member is slotted at i<SP>1</SP> to receive the end portions of angle-shaped cone-members i which are slotted at their lower ends i<SP>1</SP> to fit over a retaining upstanding flange k secured to the body a. A lip is provided on the end portion of each vane and a lower notch is also provided to receive the edge of the cap. For a projectile, the cap is normally prevented from rotation by a spring plunger m which sets back at firing to release the cap so that it can be rotated to release the striker. During this movement the slotted ends of the vanes are released from the retaining flange k and the vanes fly off leaving the nut f to act with the striker for ignition on impact. The shear pin d retains the plunger against movement until impact.

Title: Improvements in cigarette handling apparatus
IPC: A24C5/352
Filed: 1966-12-12
Abstract: 1,214,994. Endless conveyers. D. W. MOLINS, MACHINE CO. Ltd., D. W. MOLINS, and T. ROWLANDS. 11 Dec., 1967 [12 Dec., 1966; 15 March, 1967], Nos. 55562/66 and 12195/67. Heading B8A. Loaded and unloaded carriers suspended from an overhead conveyer are selectively discharged at the input of appropriate handling stations, and carriers of the opposite sense, i.e. unloaded and loaded respectively, are fed from the output of such stations to be secured to the conveyer at those positions left vacant by the detached carriers. In the embodiment shown, the carriers 28 are releasably secured to the periphery of a rotatable wheel 21 suspended from the conveyer. At a handling station the wheel engages a rail 38, which due to the motion of the conveyer, causes the wheel to rotate and thereby lower the carrier to deposit the same at the station. Similarly at the output of the station a rail 39 engages the wheel 21 to rotate the same and raise the carrier. A further rail 27 prevents rotation of the wheel in its passage between the input and output of the station. In another embodiment Fig. 6 (not shown), a pulley wheel (21) is suspended from the conveyer and has a rope (41) attached thereto, the free end of which engages a carrier. Rails (50), (53) movable between operative and inoperative position serve to rotate the pulley in the appropriate direction and thus lift or lower the carrier. In a further embodiment Fig. 8 (not shown), a pair of endless drive bands (54), (55) engage the pulley 21 to rotate the same. In a still further embodiment Fig. 9 (not shown), the carrier is engaged by a hook (222) and two further hooks (223), (224) flexibly mounted with respect to the conveyer. On approach to the input of a station the carrier engages the outer extremity of an arm (203), rotatable about its mid point by the motion imposed thereon by the carrier, and is lifted from the hook (222). On continued rotation of the arm (203) the further hooks become disengaged from the carrier and the carrier is lowered on to a storage rack (206) and in so doing pushes a carrier at the output end of the rack into engagement with arms (204) to be raised thereby for engagement with the hooks. In a further embodiment, Fig. 17 (not shown), the arms (405), (406) are driven, the drive mechanism having a lost motion device operable when the arms are approaching the vertical, the arms then being driven by the engagement with the carrier. In still further embodiment Fig. 14 (not shown) the stations have guide rails (243- 249) movable to guide a carriage (241) suspended from the conveyer into a lowered position to deposit a carrier on a storage rack, collect a further carrier and then return said carriage to its operational higher level. The carriers travel around a path more fully described in Specification 1,209,745 transporting cigarettes from a manufacturing machine to a packaging machine.
