Title: Improvements in or relating to the fuzes for rocket projectiles
IPC: F42C15/24
Filed: 1959-03-26
Abstract: 900,041. Ammunition fuzes. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. March 26, 1959 [March 28, 1958], No. 10547/59. Class 9 (1). A fuze S for a rocket projectile comprises a base part 1 housing a booster charge 4, a body part 2 in which is mounted a rotor 7 and a relay 6 and a cover part 3 enclosing an inertia mass 11 and a safety device 12, which provides the means for initiating a primer housed in the rotor. During transport the rotor is so held by the device 12 that the primer is screened from the relay 6 and when the fuze S is mounted in a hollow charge, as in Fig. 5, a flash passage extends through the device 12 to transmit flame from a percussion fuze 30. If the fuze S is to be fitted in the nose of a projectile, a firing pin 35 extends through the safety device, Fig. 9. In the spring-driven rotor 7, are two recesses separated by a nose 7p which is undercut by a groove, so that in certain circumstances a flange 14d on the sleeve 14 of the safety device can enter one recess from the other to allow movement of the rotor. The two telescoping sleeves 13, 14 composing the safety device are held apart by a spring 15 which thrusts sleeve 13 against an apertured plate 11b closing a longitudinal groove in the body 11. The groove, in addition to housing the device 12, contains a braking device comprising a rocker 17 engaging a rack 14e on the device 12 and carried by a pinion forming part of a gear train 18 to 25. On firing the projectile the body 11 sets back due to the acceleration of the shell and pulses the sleeve 13 rearwardly, thereby stressing the spring 16. The rack 14e braked by the gear train regulates the rearward motion. The flange 14d, when it gets below the level of the nose 7p, frees the rotor, which is then rotated by its spring until the flange 14d impinges on the wall of the second recess in the rotor and prevents further rotation. When acceleration of the rocket ceases, the spring 16 returns the safety device 12 to its original position, the motion being again regulated by the gear train. When the flange 14d has cleared the edge 7r of the rotor, the rotor rotates until a stop face thereon abuts the flange 14d, the primer then being aligned with the passage through the device 12 (or the firing pin 35 of Fig. 9) and the relay 6, so that the fuze is armed for operation on impact of the projectile on the target.

Title: Improvements in or relating to stock-feed mechanism for screw and similar machines
IPC: B23B13/00
Filed: 1946-04-08
Abstract: 613,147. Turning. BROWN & SHARPE MFC. CO. April 8, 1946, No. 10746. Convention date, April 17, 1945. [Class 83 (iii)] Bar stock feed means for a hollow spindle automatic screw machine comprises a stock tube, supporting means on which the leading end of the tube is shiftable into and out of alignment with the spindle, a drum and cable feeding device, a step feeding device to advance a pusher for the stock, a friction driving connection therefor for advancing the drum, and a checking device to prevent reverse cable unwinding. The stock-tube 22 is slidably supported in a swivel bracket 30 at its rear end and at its forward end is rigidly secured to a bracket 34 which is pivotally supported in a crank arm 36 on a standard 38 so that the stocktube may be moved out of line with the machine spindle for feeding a fresh stock bar into the forward end. A pusher 20 within the tube engages the end of the stock and is connected through a combined finger and anchor piece 69 by a cable 90 to a cable drum 92. The latter is mounted freely on a spindle and has a friction clutch connection with a ratchet-wheel 100 mounted coaxially. An arm 106 reciprocated from the machine by cam and lever mechanism is connected to a member 102 also rotatable coaxially with the drum and ratchet-wheel and carrying a spring-pressed pawl 104 to rotate the drum through the ratchet-wheel and friction clutch. A stop member 72, which is set according to the length of workpiece being machined, engages the end of a lever 74 when the last full length of stock has been used up and this serves to operate a trip mechanism 80 to stop the machine. A further ratchet-wheel 124 at the opposite end of the drum spindle engages a pivoted latch member 126 and prevents inadvertent rotation of the drum in an unwinding direction. This latch is tripped when a handle 46 is operated to release the stock-tube prior to swinging it outwardly and thus allows the pusher to be drawn back by the finger-piece 69 and the cable unwound from the drum prior to operations on a new stockbar. A handle 114 carried by the pawl-holding member 102 may be swung outwardly against a spiral spring 116 to effect a winding up of the drum cable by hand if required, the link 106 then being disconnected at 108 from its operating mechanism.

Abstract: 570,248. Fluid-friction brakes. NAY, L. M., and STAGNER, R. A. July 2, 1943, No. 10770. [Class 103 (i)] A brake for vehicle wheels and other rotatable members comprises vanes carried by a rotor and arranged to circulate liquid around an annular chamber formed between the rotor and a fixed casing, a member being radially movable into the chamber to restrict the flow and thus effect a braking action on the rotor. Means operable with the flow-restricting member are provided for withdrawing the vanes to enable them to pass this member. As shown, a rotor 11 keyed to the axle of a vehicle wheel 3 rotates in a casing formed by an annular member 5 and cover-plates 6, the casing being secured to the vehicle chassis by a ball-joint 10. Vanes 14 slidable in slots in the rotor are normally projected by springs 19 into an annular chamber 12 formed between the rotor and the casing so as to circulate liquid around the chamber. Reservoir chambers 24 formed in the upper part 22 of the member 5 and connected to the chamber 12 keep this chamber filled with liquid. Restriction of the circulation of the liquid in the chamber 12 to produce the braking action is effected by a member 32 slidable in the casing and adapted to be projected radially into the chamber by a manually-operated lever 39, a pinion 35 on the lever shaft 36 and a rack on the member 32. The vanes are withdrawn from the chamber 12 in the region of the member 32 when this member has been projected into the chamber by the engagement of studs 16 on the vanes with rollers 45 mounted in casings 43 secured to the member 32 so as to move therewith and slidable in recesses 18 formed in the cover-plates 6. The cover-plates are provided also with circular grooves 17 which form tracks for the studs 16 and which open into the recesses 18.

Supplying consuming devices. - An electromagnetic switch adapted to cut-off dispensable load when a desired load is exceeded has adjustable magnetic " brakes " at both the limits of motion of its operating solenoid-core or equivalent for the purpose of giving a definite quick make and break. The solenoid core may carry the switch member or itself form one of the switch elements, or it may operate at one end of a lever the other end of which carries the switch member. Fig. 1 shows a solenoid a through which all current passes with a split magnetic core e and magnetic brushes e<1> at each end. A collar e<11> connects this core with the load terminal of the solenoid. The core rests upon an insulating bush in a mercury contact foot j which is connected to the dispensable load circuit. Screws k, k<1> form the adjustable magnetic " brakes," the former holding the core in its upper position until the load current has fallen a predetermined amount below the maximum demand and the latter holding it in its lower position till the maximum demand to which it is adjusted is exceeded. In the modifications the switch is constituted by a bridge piece dipping into two mercury pots. The core may be replaced by a fine wire winding in shunt across the supply mains to effect switching on true watt values of the load.

Title: Method and Apparatus for Printing Three Dimensional Pictures
Inventor: GLENN WILLIAM ELLIS JR
IPC: G03B35/24
Filed: 1966-10-12
Abstract: 1,165,166. Stereoscopic pictures. GENERAL ELECTRIC CO. Oct.12, 1966 [Oct.12, 1965], No.11025/69. Divided out of 1,165,165. Heading G2A. A three-dimensional picture is printed from a master on to an ink-receiving side of a transparent sheet in the form of interdigitated picture elements, the other side of the sheet having corresponding lenticular lenses formed therein. The picture is applied from an inked roller 30, and contains a large number of parallel picture elements prepared as described in Specification 1,165,165. At the same time a pattern of reference lines to establish the position of corresponding lenticular elements is formed on the other side of the sheet 28, which has a layer of a thermoplastic material such as a plasticized polystyrene. These lines may be formed in different ways. Thus a pattern of a liquid having one surface tension printed, by a roller 36, on to the surface of a liquid having a substantially lower surface tension will produce thickness deformations in the latter. On heating by a heating element 34, corresponding lenticular deformations are made in the thermoplastic layer. Another method of producing the pattern of reference lines is to establish them as lines of electrostatic charge, after which heating causes the thermoplastic layer to deform along the lines of charge.
