Title: Improvements in and relating to vibratory systems
IPC: B07B1/34
Filed: 1935-12-10
Abstract: 471,877. Separating solid materials; concrete tamping machines; testing springs. JACQUELIN, A. Dec. 10, 1935, No. 34258. Void. Convention date, Dec. 10, 1934. [Class 117] [Also in Groups X and XIX] Fig. 1 shows screens 3 supported by a large number of helical springs 9, 11 in compression arranged in rows above and below the screen frame and bearing on the fixed structure. Vibratory movement is imparted to the screens by a crank or eccentric 15 and a resilient connecting rod formed by bowed springs or connected to the screen frame by resilient coupling means. Alternatively, the actuating means may comprise double-acting cams or rotary eccentric weights. As shown, two screens are connected by a lever 17 and links so as to move in opposite phase for balancing purposes and the actuating force is applied to one of them. Fig. 7 shows a pneumatic coal-cleaning apparatus in which the air pervious table 38 is suspended from a member supported on springs 29 on the stationary structure. The air box 30, connected to the table by a flexible bellows 33 and having flap valves 32 is also supported on springs. Motion is imparted to both the table and the air box by an eccentric or crank-shaft 34 and connecting rods 35. Fig. 5 shows a concrete tamping device in which the shoe 24 is given a tamping and stepby-step progressing movement by the reaction of a member supported on springs on the shoe frame and vibrated by a crank and connecting rod mechanism mounted thereon. A device for testing springs is referred to in which the springs are placed between a vibrating plate and fixed plate which may be adjustable by rods and nuts. The Specification also refers to the application of spring-mounted vibrating bodies to devices such as crushers, pile-drivers and mechanical loaders, but, in this respect, the description does not admit of satisfactory abridgment.

Title: A power transmission device
IPC: H02K49/04
Filed: 1957-11-04
Abstract: 844,965. Electromagnetic couplings and brakes; transmitting mechanical power. COHEN, E., and ROTH, S. Nov. 4,1957 [April 23, 1957], No. 34311/57. Classes 35 and 38 (4). A power transmission device comprises a ferromagnetic cylindrical rotatable driving member 5, a coaxial stationary member 14 having two axially spaced windings 15, 16 each facing and co-operating with a different portion of the driving member 5, two ferromagnetic driven members 12, 13 each interposed between a respective winding 15 or 16 and the corresponding portion of the driving member, and two mechanical drives 17, 19, 20, 21 and 18, 22, 23 having different speed transmission ratios and respectively coupling the driven members 12, 13 with a rotatable output member 2, the arrangement being such that when only one of the windings is energized, magnetic flux penetrates the associated driven member and driving member portion whereby if the latter member rotates the output member 2 is driven via such driven member and its respective mechanical drive. If, instead, the other winding is energized the output shaft 2 is driven at a different transmission ratio, and if both windings are energized simultaneously a braking effect is produced which depends upon the relative values of the currents supplied to the windings. The two mechanical drives shown rotate the output shaft in opposite directions, but in a modification the drives are constructed to rotate the output shaft in a single direction but at two different speeds. The winding selection is made by a switch not shown and means may be provided for varying the energizing currents between zero and a maximum. The shafts 1 and 2 may be coaxial. Specifications 764,811, 790,080 and 823,977 are referred to.

In a refuelling machine for a water-cooled nuclear reactor, adjustment of the machine is effected by water in an hydraulic mechanism in which the water pressure is higher than that in the reactor. Thus, no leakage of contaminated reactor coolant occurs and in addition the high pressure water of the refuelling machine is not vaporizable at the reactor temperature. The machine may provide a periscope and fuel element spray and consists of a vertical magazine having coaxial fuel element housings. The magazine is rotatable about the vertical axis so as to align a selected fuel element housing with a core standpipe. The lower end of the machine is telescopic and may be extended hydraulically into engagement with the upper rim of the standpipe to which it is sealed by an hydraulic coupling. The telescopic coupling incorporates knuckle joints to allow for misalignment between the magazine and standpipe. After re-fuelling, the standpipe is sealed by a closure urged into engagement with the standpipe by an hydraulically operated thrust member in the telescopic coupling.

Title: Improvements in apparatus for making illuminating gas from air and petrol and the like
IPC: C10J1/14
Filed: 1921-12-23
Abstract: 195,161. Kent, Ltd., G., and Graham, J. T. Dec. 23, 1921. Carburetting.-Carburetting apparatus comprises an air-bell b, a carburettor c, a gas-holder a, and weight driven mechanism comprising a shaft f provided with a drum having coiled around it a rope connected to a weight n<7> and fast upon which are two cams g one cam being normally engaged by a detent arm m preventing rotation of the shaft and' the other by an arm o' carried by a pulley e loose on said shaft and from which the air-bell b is suspended. The mechanism is controlled by the gas-holder only and each cam is provided with two teeth 180‹ apart. The carburettor c is arranged in the interior of the air-bell and comprises an open-topped casing surrounding a series of cones and perforated trays c<2>, c<3> respectively threaded on the petrol supply pipe d over which petrol from orifices d<1> at the top of the pipe d trickles, air being supplied to the carburettor upon upward motion of the airbell b through valves c', and carburetted air passing to the gas-holder a through a pipe a<3> when the air-bell falls, thus causing the gasholder to rise. The shaft f is normally driven by the weight in an anti-clockwise direction to raise the air-bell and upon the gas-holder falling a projection a<6> thereon strikes a lug i<1> on a rod i the downward movement of which operates a weighted quadrant which withdraws the detent m from engagement with one tooth of the first cam, thus allowing the shaft to rotate and thereby rotating the pulley e to raise the air-bell b through the medium of the second cam and the arm o<1>. The rotation of the pulley restores the quadrant to its normal position and allows the detent arm m to engage the second tooth on the first cam g after half a revolution of the shaft, a brake being provided to engage the arm o<1> and bring the pulley gradually to rest. Petrol is supplied to the pipe d from a storage tank s, the pipe d being connected to a funnel w in said tank which receives petrol from a bucket v pivoted to a cradle u also pivoted to arms t, t<1> fast on spindles r', r<2> journaled in the petrol tank. Fixed to the spindle r' is an arm r connected to a lever q<2> operated by a cam q fast on the shaft f, so that rotation of the cam q will operate the said link motion to raise and lower the bucket v. Near the end of the upward stroke of the bucket a stop v<1> tips the bucket, allowing petrol to fall into the funnel w from whence it passes through the supply pipe d or a return pipe y leading back to the tank, the flow through said pipes being controlled by a single plug cock w<1>.

Title: Improvements in or relating to electrically-driven railless road vehicles with trolley current collectors
IPC: B60K1/00
Filed: 1932-12-08
Abstract: 398,066. Railless trolley electric road vehicles. RACKHAM, G. J., 222, Sheen Road, Richmond, Surrey, and ASSOCIATED EQUIPMENT CO., Ltd., Windmill Lane, Southall, Middlesex. Dec. 8, 1932, No. 34892. Addition to 380,536. [Class 79 (iii).] In an electrically-propelled railless road vehicle of the trolley current-collector type, the motor is located outside the chassis frame, viewed in plan, but lies inside the side wall of the vehicle body and wholly below the floor level, the drive being transmitted, as in the parent invention, to one or more axles at a point located between the side springs which are situated near the ends of the axle or axles. Such point may, further, lie between the chassis longitudinals and the transmission to the axle may be through a worm-and-wheel with the axis of the worm directed towards the motor so that it lies otherwise than at right-angles to the axle, as described in Specification 380,670. As shown in Fig. 2, the longitudinals 11, 12 are close together at the front end, diverging at the rear, the motor 10 being placed between the longitudinal 11 and the side wall 15 of the body, a removable panel facilitating access thereto. The motor, which is supported on brackets 21, 22, 23, is aligned with the transmission shaft 17 which drives the rear axle 18 through worm gearing 19 located between the springs 13, 14 and also between the longitudinals. The shaft 17, which is preferably provided with a universal connection 20, may pass under the longitudinal 11 or through an aperture therein. In the form shown in Fig. 4, with twin pairs of rear wheels, the rear axle 18 is driven, the motor being supported, with its axis parallel to the longitudinal axis of the vehicle, by cantilever beams 24, 25 attached to the longitudinal 12 and bearing on the top of the longitudinal 11. In Fig. 8, the worm gearing 19 is partly outside the longitudinal 11, which is straight, and the axis of the worm is askew to the wheel axle 18 being in line with the transmission shaft 17 which drops, the motor being supported with its axis horizontal bv brackets 28, 29. Further arrangements are shown in which the skew worm drive is applied to twin rear wheels as in Fig. 4, either the front or the rear axle or both being driven. In the latter case, the worms are connected by a short extension shaft and are inclined in opposite directions, Fig. 10 (not shown).

Filed: 1964-08-26
Abstract: 1,083,022. Packaging-machines. PACKAGING INDUSTRIES Ltd. Inc. Aug. 26, 1964 [Sept. 12, 1963], No. 34965/64. Heading B8C. [Also in Division B5] Apparatus for securing a plastics or cardboard closure to the flanged mouth of a plastics container includes a support apertured to receive the container body and heating means comprising an electrical resistance strip conforming in shape to the flange and either surrounding the aperture or mounted in a pressure plate above the support, the heating means being conneotible to sources of current at different voltages to cope with the demands of the various shapes of heating element. The device may secure covers over filled blisters in a web. The supports may be readily changed to accommodate different-sized packages and packages requiring different sealing temperatures. In one embodiment, rails 12, 14<SP>1</SP> carry container supports 18, 20 and pressure plates 100, 150 mounted individually on rollers, the arrangement being that a support and superposed pressure plate are beneath a vertically movable plunger 42 while the other support is being loaded. As shown, the support 20 is loaded with filled containers and covers are placed upon them, the latter being located by retractable pins (not shown). The support is then advanced to the left and picks up the pressure plate 100. Both move beneath the plunger 42, the assembly 150, 18 having been drawn out to the left. In so moving, the plate 150 is halted clear of the pressure applying station and the support 18 passes-from beneath it to expose the scaled packages for removal. A polytetraflourethylene strip 110, Figs. 9, 9A (not shown), may join each support and plate and extend between them during sealing. In another embodiment, Figs. 1-3 (not shown), the plunger carries a single pressure applying plate and supports are slid beneath it on rails. The supports may each have differentshaped apertures each surrounded by a heating element. In both embodiments spring-loaded retractible stripper pins thrust the package clear of the pressure plate when the pressure is removed. The heating elements are thin uniform width strips such as the rectangular frame in Fig. 4 (not shown), of stainless steel or other relatively high-resistance conducting material. Current is supplied at two equidistant points, L1, L2 on opposite sides of the frame. The strips may be non-continuous (Fig. 4c, not shown). They may be backed and covered by glass cloth or the like, the covering being polytetraflourethylene coated or impregnated. The circuits may be formed through the supports and pressure plates and the stripper pins may act as connectors between them. The differing voltage demands for various lengths of strips as a support for different-sized containers are catered for through sets of terminals for the respective voltages.

Title: An improved process for printing cinematograph films
IPC: G03B27/08
Filed: 1929-11-15
Abstract: 345,230. Printing kinematograph films. HEIDE, E. WOLFF-, 16, Kopenhagenerstrasse, Berlin. Nov. 15, 1929, No. 34986. [Class 98 (ii).] In printing from perforated films on to unperforated film stock the films are first temporarily united by means of moisture only, the intermittent feed being directly applied to the negative film only which carries the sensitized film with it through the printing gate. After leaving the printing gate the printed film is separated and passes through a perforating machine, which is synchronized with the intermittent feed and punches the four holes of a picture space after each feed movement. The films are first united in lateral register by passing them in a wet state over a curved support having guide flanges and pressing them in contact by a roller. The method is particularly applicable to the process of Specification 332,893, [Class 98 (ii), Photographic processes &c.]. Specification 14433/12, [Class 98 (ii), Photographic processes &c.], also is referred to.
