Title: Improvements in and method of producing caps or capsules for bottles and other receptacles
IPC: B29D99/00
Filed: 1924-06-26
Abstract: 218,310. Pacchioni, G. Marchi-. June 27, 1923, [Convention d,ate]. Void [Published under Sect. 91 of the Act]. Capsules; making capsules; materials, special, for capsules.- Caps or capsules for sealing closures for bottles &c., or for use as closures, are formed by dipping a mould or core, such as is shown in the Figure, into a composition comprising animal glue dissolved in spring water to which is added 3-10 per cent of glycerine, the mixture being stirred in a heated water-bath. The composition may be coloured by adding an aniline dye dissolved in spirits of wine, or may be rendered opaque, with or without colouring, by zinc oxide &c. The capsules are stripped from the moulds before they are entirely dry. allowed to set, and then immersed in a solution of formalin of 5-10 per cent strength to give them elasticity, durability, and impermeability. Capsules thus obtained may be preserved in a dry state and are softened for use by soaking in water. When the caps are intended for use as closures in a dry state, they are replaced on the moulds after the treatment with formalin and allowed to dry thereon. The moulds may be of a shape to form capsules with mouths narrower than their bodies as shown, and marks or designs a may be engraved on the moulds to produce markings standing out in relief on the capsules. It is stated that the composition specified may be used for all purposes in which a substance is required that is soft when produced, and thus mouldable, and dries without losing its properties.

Title: Anti-friction and auto-lubricating product
IPC: C22C1/00
Filed: 1932-06-02
Abstract: A self-lubricating alloy is made by melting and mixing together the metal constituents of the alloy, cooling the mixture to a pasty condition, and then adding a lubricating material, such as a fat, to the mixture.  Graphite may also be added to the alloy. To improve the homogenity of the mixture, cadmium or bismuth may be added thereto. The alloy is then forced out of a press while in the pasty state on to the parts to be lined, or is heated to the fluid state so that it can be cast.  In the latter case, the molten mixture is preferably covered with a layer of thermic insulating body to prevent loss of heat.  Such a body might be a fatty body which burns to give up heat to the molten mixture.

Title: Press Position Control
Inventor: COLLINSON CHRISTOPHER DAVID
IPC: B21J9/20
Filed: 1966-04-07
Abstract: 1,190,791. Forging. DAVY & UNITED ENG. CO. Ltd. 23 June, 1967 [7 April, 1966], No. 15725/66. Heading B3H. A press position control system of the kind described in Specification 1,114,234 is used to control oppositely movable swaging tools with concave or V-shaped working faces, by including swage gap setting means operable before a swaging operation with the swaging tools closed together, for automatically feeding to the tool control means the selected swage gap. A signal representing the position of the moving tools is fed to the main counter 13, as described in Specification 1,114,234. Prior to swaging the selected swage gap is set by switches 12 and an oscillator 16 generates pulses which are fed to counter 13 through AND gate 15 controlled by flip-flop 17. When the count coincides with the selected gap a coincidence unit 14 triggers an AND gate 18 which opens to stop the count. The counter 13 is thus present to provide a false zero setting corresponding to the required swaging gap. Thereafter the desired workpiece size is set on switches 12 and the swaging tools are moved towards each other until counter 13 coincides with switch setting 12.

Title: Improvements in coin-freed vending machines
IPC: G07F5/08
Filed: 1939-05-31
Abstract: 529,421. Coin freed vending machines. HARPER, P. S., and HARPER AUTOMATIC MACHINE MANUFACTURING CO., Ltd. May 31, 1939, No. 16009. [Class 27] In coin-freed vending machines the discharge mechanism can be set to operate at any price value within a given range by a selector which can be pre-set to associate any one or a plurality of a number of coin-operated members with the discharge-mechanism. In Fig. 2 there are four coin-release units A, B, C, D of which D; C and B are operated by 1s., 6d. and ¢d. respectively, and A is operated by any number of pence from one to five. The units A, B, C each unlock one of the superposed sliding bars 2 when the appropriate coin is inserted, while the unit A operates one of five other bars 2 according to the number of pence inserted. The purchaser pulls out one of a series of draw-bars 4, Fig. 4. This operation causes a pin 12 on the draw-bar to swing a bracket 14 clockwise about the pivot 15. On a vertical shaft 8 are eight levers, one for each of the bars 2, any number of which can be pre-set with the bulbous noses 6 in engagement with the recesses 10 in the corresponding bars 2. In this position, the recesses 7 are engaged by the projection 18 on the bracket 14, so that all bars 2 thus engaged are moved axially as the 'draw-bar is operated. Until the draw-bars are unlocked, however, by the insertion of appropriate coins, this axial movement cannot take place and thus the drawbar cannot be pulled out. Figs. 6 and 8 show the coin-action. The operation is based upon the sliding-action of members 21 which affect the unlocking of bars 2 by means not shown when they make a full movement towards the right in Fig. 6. Normally such movement is prevented by stops 31 engaging members 28 pivoted at 29 in the sliding members. The coin trips a projection 32 mounted on the pivot 29 by sliding the member 21 rearwardly. As the coin passes, a spring restores the slider and the projection 32 is tilted upwards by engagement with the edge of the coin. This also tilts arm 28 to free it from the stop 31 and thus allows the spring to give the slider its full movement. This movement additionally operates the lever 23 and rotates shaft 25 to remove the support 27, Fig. 6, and release the coins. In the multiple-coin slot each coin unlocks one bar 2, but only those bars that are coupled to the draw-bar are moved axially by the purchaser in obtaining supplies. Fig. 8 shows one construction in which the slider 21 is geared to the bar 2 by rack-and-pinion mechanism 35 ... 38.

Abstract: 730,515. Cooling dynamo-electric machines. ALLIS-CHALMERS MANUFACTURING CO. June 11, 1953 [June 20, 1952], No. 16105/53. Class 35. In a machine wherein gas or air flows radially inwards through stator passages towards the air gap and then outwardly through other passages away from the air gap, screens are provided to prevent gas or air leaving the rotor from entering the passages used by the radially inwardly flowing stator air or gas. As shown, the stator has radial ducts each so sub-divided that in some parts 32 around the core periphery hydrogen flows towards the air gap and in others 33 returns to the outer periphery of the stator core whence it returns to the two ends of the machine for re-circulation after passing over coolers. Hydrogen is also forced by a separate two-stage fan to flow at high pressure through ducts 51 formed of spaces between trapezoidal rotor conductors, these conductors and the rotor slot wedges having cut-out portions to enable the gas, especially near the centre part of the rotor, to flow radially outwards to the air-gap. This gas then passes through apertures 44 in plates 41 forming a screen for the stator and joins the outwardly-flowing stator gas. The apertures 44 are so positioned, and baffles 34, 43 provided to prevent the rotor gas impinging on the stator conductors or opposing the flow of stator gas. In a modification, the rotor cooling ducts are in the teeth and not in the conductor slots, the tooth ducts being closed by spaced wedges, the gas flowing into the air gap of the spaces so provided. It is stated that the machine could, alternatively, be open and air-cooled. Specification 729,231 is referred to.

IPC: G03G15/34
Filed: 1955-06-06
Abstract: 790,651. Copying-telegraphy. HUEBNER CO. June 6, 1955, No. 16129/55. Class 40 (3). Images are recorded by means of an assembly of needle-like discharge elements 24 co-operating with a like assembly of attraction elements 25 and forming therewith a gap across which a desired pattern of electrostatic fields is produced by the simultaneous energization of selected pairs of discharge and attraction elements. A web 25 of recording material, such as paper, is disposed in the gap and the recording is made by fine particles or atomized liquids which are injected into the gap from a pressure conduit 30 and are directed on to the material of the recording paper under the action of the electrostatic fields. Surplus recording material is extracted by a vacuum conduit 31. The recording appears as a pattern of dots corresponding to the pattern of energized elements. Sharply formed dots are maintained by magnetic focusing provided by a coil 37 and small stems 36 of iron filings and plaster formed around each attraction element. The energization of the elements in accordance with an image it is desired to record, for example a letter H in a transparency 11, is effected by connecting each pair over a separate control circuit to an assembly of photo-sensitive elements 15 on to which is projected light from a source 10 passing through the image. The photo-sensitive elements comprise germanium photo-diodes, and the associated control circuits include transistor amplifiers 23 which energize the recording elements either directly or via relays and separate high-potential circuits.

Title: Improvements in devices for arresting backfire in fuel pipe lines
IPC: A62C4/02
Filed: 1932-06-08
Abstract: 389,324. Backfire arresters. POLLAK, J. E., 20, Holborn, London.-(Kemp Manufacturing Co., C. M.; 405, East Oliver Street, Baltimore, U.S.A.) June 8, 1932, No. 16191. [Classes 54 and 135.] A device for preventing the continuance of a backfire down a pipe line conveying gaseous fuel comprises a spring-pressed valve 13, Fig. 1, located in a casing 11 inserted in the pipe line, which valve is maintained open by a fusible or frangible link 35 connected to a flexible diaphragm 34 and is free to close on the link being fused by the hot gases in the backfire or being broken due to the distortion of the diaphragm by the pressure of the backfire. The link 35 is connected by a wire 36 passing through a tube 33 and an elbow 26 to a trip member 24 which, by means of links 22, a lever arm 21, and a tappet arm 19, fixed to the same spindle as the lever arm and engaging a projection 18 on the valve spindle, maintains the valve open. Gas from the source of supply passes through the casing 11 by a neck 29 to a chamber 30, whence it reaches the pipe 33 leading to the point of consumption by way of nipples 31 and a chamber 32, the lower wall of which is formed by the diaphragm 34. The nipples 31 have gauze cylinders 31<1> which prevent flame passing down the pipe 33 from reaching the chamber 30 and the valve. In a modification, Figs. 3 and 4, the spring-loaded valve 56 is prevented from closing by a lever, one arm 62 of which engages a disc 60 on the valve spindle and the other arm 78 of which has a slotted projection 88 engaging a reduced part of a link 80, and is held by a strip 87 soldered to the link. This link is suspended from a hook 84 secured to the wall of the casing, one part of which is formed by a diaphragm 81. When an explosion distorts this diaphragm, a nut 95 on a rod 93 passing through the link 80 and securedlto the diaphragm forces the link 80 off the hook 84 and out of the slotted projection 88, so that the valve can close. Flame or high temperature alone releases the soldered strip 87 and consequently the valve. Between the valve and its releasing means is a partition wall 64 wherein are secured flame-interrupting gauze cylinders 71 fitted in removable tubes 72. In another modification, the diaphragm is omitted and the valve-releasing means are responsive to the heat of the backfire only.
