Filed: 1945-05-29
Abstract: 593,272. Variable - pitch propellers. COWLEY, W. L. May 29, 1945, No. 13440. [Class 114] In a variable pitch airscrew propeller provided with flyweights 7 to balance the centrifugal twisting movement of the blade 2, the pitch changing is effected in both the fine and coarse sense by application of hydraulic pressure to the respective ends of a a movable cylinder 4, operating on a fixed piston, and connected by links, housed in the guides 6, to an eccentric at the root of the blade 2. Four sets of flyweights 7 are pivotally connected at 12 to the cylinder 4 and at 13 to the fixed front plate of the hub 1 by the links 10 and 11 respectively. On rotation of the propeller, the weights 7 under centrifugal action tend to move the cylinder 4 in the pitch-coarsening direction thereby compensating the effort of the blade centrifugal twisting moment to move the cylinder 4 to the fine pitch position which is indicated in dotted lines in the drawing.

Title: Improvements relating to insulated electric cables
Inventor: JOHNSON OLIVER SANDERS
IPC: H01B7/29
Filed: 1965-03-30
Abstract: 1,131,494. Connecting pieces; cable terminations. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 29 April, 1966 [30 March, 1965], No. 13449/65. Heading H2E. [Also in Division H1] In order to reduce excessive temperatures at cable joints due to the greater insulation that may be needed at these joints end portions of the conductors of a high-voltage insulated cable are made of conductive material of lower electrical resistivity than the material of the remainder of the conductor so that the resistance per unit length is less over the end portions than over the rest of the conductor. For example, in a cable having an aluminium conductor a length of copper may be brazed or cold welded to each end of the aluminium prior to the application of the insulation. The wires or segments of the conductor may be joined to individual wires or segments of the end portion and these joins may be staggered to avoid an abrupt change in the mechanical properties of the conductor, or the wires or segments may be joined en masse to the end portion. As shown, an oil-filled cable consists of six segments 2 laid about a central oil duct 3, and bound together by bronze tapes 7. The layers of oil impregnated paper insulation 4 are covered by a metallized paper screen 8 and a lead sheath 5 which is further protected by bronze taper 9 and a P.V.C. sheath 6.

Abstract: 600,555. Aerial bomb fuzes. VICKERSARMSTRONGS, Ltd., MORPETH, W., and HESELTINE, J. C. W. Aug. 18, 1943, No. 13486. [Class 9 (i)] An aerial bomb is electrically detonated before reaching ground or target, by completion of the firing circuit by an impact member located at the forward end of one of a number of telescopic members which are projected in advance of the bomb casing by a propellant charge on release of the bomb. When the bomb is released, a pin 11, Fig. 2, is withdrawn to free an impact member 8a coupled through a copper diaphragm to a switch 8 located at the forward end of the inner tube 3 of the telescopic system 3, 4, 5 these tubes being provided with split or deformable locking rings which prevent closure of the telescopic system once it is extended. The tube 3 is sealed at its forward end by a plug 3a and when released by removal of the pin 11 moves forward under the influence of a spring 12, Fig. 3, thereby releasing locking members 18 from a spring-urged striker 13a which thereupon strikes a percussion cap 14 and ignites a delay train 15 which relays to a cordite propellant charge 16 whose function is to extend the telescopic system. The movement of the striker body 13b, Fig. 4, is used to displace a shutter 25 to release a safety switch 24 to prepare a firing circuit through a battery 22a, cartridge contact 26-and electric tube 26a for initiating detonation, the firing circuit being completed by the switch 8, Fig. 2, and cable 26c on impact. According to a modification the safety switch is provided with a plunger and is closed by the pressure of the gases used to extend the telescopic system. The telescopic system may be located as an extension at the forward end of the bomb instead of being housed therein. Specification 600,557 is referred to.

Title: Automatic sacking and weighing apparatus
IPC: B65B1/18
Filed: 1928-05-10
Abstract: 315,939. Jarrier, R. May 10, 1928. Packing pulverulent substances into sacks.-A machine for simultaneously sacking and weighing granular or powdered material comprises a truck carrying a sack-holder and adapted to be pushed onto the platform of a weighing-machine, and a filling device that is stopped when a sack on the truck contains a predetermined weight of material. The filling device comprises a feed hopper 1, Fig. 1, from which material is fed along a. tube 2 into a sack 3 by means of a conveyer worm 4 driven by a motor 9. The pitch of the worm 4 increases in the direction of feed to prevent clogging. Operation of a slidable starting handle 50 removes a pivoted strut from beneath the weigh-beam 32. The consequent downward movement of the beam causes a contact 37 on a counter-weighted lever 34 to enter a mercury cup 41 and start the feed motor 9. When the required weight of material has entered the sack, the weigh-beam rises and the motor circuit is broken. In a modification, Fig. 6, the switch lever 34 is replaced by a lever 59 having a pair of connected contacts 66 for insertion into mercury cups 69 in the motor circuit. To start the motor a pivoted counter-weight 61 is rocked by a handle 64 to move the lever 59 into horizontal position. As the weigh-beam rises, it contacts with an extension 65 of the lever 59 causing the weight 61 to rock and thereby effecting a quick break of the motor circuit. The sack is gripped by two pairs of jaws 23, Figs. 1 and 4, formed by members 24, 26 that are supported on vertical rods 25, the member 26 being fixed to the rods while the members 24 are pivoted thereto. The jaws are faced with rubber and are held closed by a pin 27. The rods 24 are adjustably supported within the upper ends of a pair of trestles 22 carried by a platform 17 that is pivotally mounted in bearings 15 disposed to one side of a wheeled truck 12. Depression of a pedal 21 allows the platform 17 to tilt under the weight of the sack so that upon release the sack drops clear of the truck. A counter-weight 18 returns the platform to normal position. The members 26 are slidably connected and one treadle 22 is slidably mounted to allow the distance between the jaws 23 to be adjusted.

Abstract: 547,789. Alternating current motors; electric clocks. LANDIS & GYR SOC. ANON. Oct. 29, 1941, No. 13907. Convention date, Dec. 30, 1940. Addition to 448,080. [Class 35] [Also in Group XVIII] Relates to synchronous motor-driven clocks, time-switches &c. in which an auxiliary spring drive is allowed to come into action as the result of the axial return movement of the rotor shaft under spring control when the supply fails, as described in the parent Specification. According to the present invention, the forward axial movement of the shaft 5 is affected, against the action of the spring 6, not only by the pull of the stator field but also by a supplementary field produced by an auxiliary coil 12 surrounded by a slotted iron ring 13 and acting on the hub 17 which constitutes an armature to the core 10 of the stator. The supplementary coil may be in series with the field coil of the motor or in parallel with part of it. The axial movement, when the supply is on, effects movement of the lever 8 to shut down the escapement of the auxiliary spring drive as in the parent Specification.
