Title: Improvements in wire twisting machine
IPC: D07B3/10
Filed: 1961-01-03
Abstract: 959,896. Wire twisting machines. SYNCRO MACHINE CO. Jan. 3, 1961 [Sept. 6, 1960], No. 250/61. Heading D1T. A wire bunching or twisting machine has a reel-supporting cradler 66 weighted so as to be supported against rotation within first and second oppositely rotating frames 36 and 10 respectively. Wires W, that are to be twisted together, are led through a nozzle 30, around pulleys P 1  to P 4  on the frame 10, around pulleys Ps to P 8  on the frame 36, and thence to a take-up reel 96 carried by the cradle 66 to produce four twisting actions. The reel 96 is driven through a slipping clutch 92. Frame 10 is rigid with a pulley 20 driven by a crossed belt 22. Frame 36 is rigid with a gear 64 driven by a pinion wheel 62 carried by the frame 10, the pinion wheel 62 being driven by a gear wheel 56 rigid with a pulley 50 driven by a belt 52. In a modified construction the rotational axis of the reel 96 is coaxial with the axis of rotation of the frames 10 and 36. By omitting the pulley P 8  and moving the pulley P 7  to the left, the machine now produces three twisting actions instead of the previous four. Instead of drawing the wires W into the above described machines the operation may be reversed by mounting wire supply neck and the nozzle 30 in the cradle 66, the resulting bunched or twisted wires being drawn off the pulley wheel P 1  by a capstan and take up reel.

Title: Improvements in cameras having automatic film threading devices
IPC: G03B1/56
Filed: 1962-01-03
Abstract: 987,881. Automatic threading in Cine Cameras. CONTINA BUREAUX-UND RECHENSMASCHINENFABRIK A.G. Jan. 3, 1962 [Aug. 3, 1961], No. 271/62. Heading G2E. A cine camera provided with a device 21-27, 32-37 for automatically threading the leading end of a film into the slotted hub of a take-up spool is shown in Fig. 1 with said device in operative position in which two lugs 26, 27 of a pivoted guide 23 are engaged in a slot 28 in the spool hub 29 thereby locking the spool 11 against movement by its friction drive. The guide 23 is rigidly connected to a further guide 24 and the whole is under the influence of an over centre spring arrangement 32. A weak spring 37 tends to oppose the spring 32. On actuating a camera release 8, film 18 from a supply spool 10 is fed by the usual claw mechanism (not shown) over a guide 16, under a retractable pressure plate 17, between stationary guides 21, 22, between guides 23, 24 and into the slot 28 where its leading end is checked. Further feeding of the film causes a bulge to form which presses against guide 24, whereby guides 23, 24 are pivoted into their alternative positions, shown in dotted lines in Fig. 1. By this means, the spool 11 is freed to enable the whole of the film 18 to be taken-up. In a modification (Fig. 6) in which the guides 23 and 24 are separately pivoted about pin 33 but are still engaged by the springs 37 and 32 respectively, two lugs 43 and 44 are provided on the guide 24 engageable by guide 23 so as to always ensure sufficient spacing 45 for the film to pass. Guide 23 may have a cut-out portion 54 (Fig. 7) to reduce damage to film surfaces. A cam surface 53 may be provided on the plate 24 for co-operation with a camera cover plate whereby when said cover is closed the guide 24 is automatically moved out of its threading position. Alternatively, if it is desired to load the film with the cover on, it may be arranged for the closing of the cover to bring the threading device into its operative position.

Title: Improvements in processes for lacquering metal surfaces
IPC: C09D167/08
Filed: 1928-01-05
Abstract: 283,162. British Thomson-Houston Co., Ltd., (Assignees of Barringer, L. E.). Jan. 5, 1927, [Convention date]. Coating-processes; lacquers.-Metal surfaces which are to be lacquered are first provided with a primary coating of a polyhydric alcoholpolybasic acid resin such as a glycerol-phthalic acid resin. Suitable resins are described in Specification 3271/13; and 8417/13, [Class 140, Waterproof &c. fabrics], and they may be applied in a solution, which should contain little or no pigment or filler. Plasticizers such as indene, indene polymer, glycol diacetate, diethyl phthalate, tricresyl phosphate, triacetin, or anisol may be introduced into the resin during its manufacture. The resin is preferably applied in the A stage of condensation (cold soluble) and baked to convert it into the B stage (infusible but swelling in cold solvents), or it may first be converted to the C stage (infusible and non-swelling in cold solvents) and dispersed in a solvent. In examples (1) a solution or glycerol-phthalate resin (A stage) in 30 parts of acetone, 30 parts of benzol, 30 parts of alcohol and 10 parts of ethyl acetate by volume is applied and locked for 20-40 minutes at 125-175‹ C., thereby converting the resin to the B stage. (2) C-stage glycerol-phthalate resin is dispersed in acetone or acetone oil by heating in a autoclave, to about 150-170‹ C. for about 36 hours. After application some baking is desirable. After application of the resin, a cellulose or other lacquer, preferably opaque, such as a resin solution as previously described containing pigment or filler, is applied. The lacquer should contain a solvent such as butyl or dibutyl phthalate, ethyl lactate or acetate, glycol diacetate &c. which will soften the priming resin and bind the two films together. Metals coated by the process are suitable for refrigerators and other food containers, ornamental and electrical ware, &c.

Title: Improvements in or relating to long flow carbon
IPC: C09C3/08
Filed: 1955-01-06
Abstract: Carbon black is treated with for example 0.2 - 2.5 per cent of calcium, strontium or barium mahogany sulphonate.  Mahogany sulphonic acid is formed during the refining of lube or white mineral oils with sulphuric acid.  The sulphonate may be admixed dry with the carbon black or may be applied as a solution of for example 2-60 per cent, preferably 30-60 per cent, concentration. The solvent may be an aliphatic or aromatic hydrocarbon for example pentane or benzene, a vegetable oil for example linseed oil, or an animal oil.  The mixture may be heated up to 150 DEG C.  A non-volatile solvent may be employed.  The carbon black may absorb up to 15 times its weight of the non-volatile solvent while remaining in a dry condition.  The dispersibility of the treated carbon in liquid media may be increased by the use of 1-5 per cent of gilsonite, rosin, or limed rosin.

Title: Rotary retort for the distillation of carboniferous material
IPC: C10B1/04
Filed: 1934-01-05
Abstract: 431,397. Distilling solid carbonaceous materials. HOLFORD, H. J., 2, Brookvale Road, Southampton. Jan. 5, 1934, No. 443. [Class 55 (i)] Carbonaceous material such as coal, peat, lignite, torbanite, shale, cannel coal, coal slack is carbonized in thin layers on shelves, the heating means comprising direct contact with superheated steam and a body of heated refractory material in proximity to the distillation zone. The finely divided material is fed from a shoot 39 into rotating distributers 19, through a mesh screen 29 on to the dome 43 of a rotating inner chamber 42, from which it is distributed to superposed shelves 92 on the outside of the chamber. The material is transferred down the shelves by rabbling arms 95 fixed to a surrounding immovable casing 94 and is heated in its descent from hot refractory elements 66-69 within the inner chamber 42 and simultaneously by the introduction of superheated steam, for example at 500‹ C., through nozzles 96, 196, 296, 396 and 496 arranged in four vertically disposed banks. Some of the distillation products flow through openings 98 to an air condenser 99, condensates being removed through a conduit 128 ; the remaining and mainly non-condensible products flow through openings 102 in the fixed casing to an annular collecting chamber 101 communicating with the condenser. The gases are removed from the latter via suction pipes 103, 112, 113. The refractory elements are heated from a group of nozzles 88 supplied with superheated steam from a conduit 90 or with gas from the same conduit and compressed air from a conduit 91. The direction of flow of the hot gases around the refractory elements is determined by a rod 74 carrying dampers 75, 76 and 77. The annular shelves may be replaced by a continuous helix. Specifications 296,108, [Class 55 (i)], and 352,487 are referred to.

Title: Improvements in or relating to apparatus for sensing electrically conductive marks on record cards or sheets of moisture absorbent material
Filed: 1944-01-11
Abstract: 574,492. Statisticalapparatus. BRITISH TABULATING MACHINE CO., Ltd. Jan. 11, 1944, No. 530. Convention date, Jan. 12, 1943. [Class 106 (i)] In apparatus for emitting electrical impulses on the sensing of electrically conducting marks on moisture-absorbing material, means are provided for sensing the conductivity of the material and .reducing the voltage applied to the means for sensing the conducting marks when the conductivity of the material increases, so that impulses will continue to be emitted in accordance with conducting marks only. The record sheet S with conducting marks D is adapted to move in the direction of the arrow under sets of brushes arranged above each column of marks. The outer brushes BE of a set are connected through a lead 10 to the positive side of a 110 volt circuit and the centre brush BC is coupled through a lead 12 and resistance R to the grid G of a valve A. Current flows in the anode circuit of the valve to operate a magnet M when the potential of the grid G is raised due to the brushes contacting a conducting mark. A set of brushes for sensing the conductivity of the material is arranged to co-operate with a column having no conductive marks. The outer brushes of the set are connected to the positive side of the 110 volt circuit through the wire 10 and the centre brush is connected by a wire 14 to a socket 15 connected to the grid G<1> of a valve C, the normal negative bias of which is sufficient to render the valve non-conductive. Increase of conductivity of the material reduces this grid bias until the valve becomes conductive with consequent reduction of voltage in line 10 due to increased voltage drop in resistance R. This decreased voltage is sufficient for sensing the conducting marks due to the increase in conductivity of the material to which they are applied. Instead of a separate set of brushes, a special brush SB coacting with an outer brush BE of a set may be used, the resistance R<2> being replaced by one of lower value or the grid bias on valve C being reduced accordingly.

Title: Method of recovery of precious metals
IPC: C22B11/08
Filed: 1947-01-07
Abstract: Precious metals, i.e. gold and/or silver, are recovered from a cyanide pulp containing them by adding a granular adsorbent to the pulp, the adsorbent having a particle size greater than that of the pulp solids and then separating the adsorbent by screening. The ore pulp and cyanide may be ground and classified, the oversize being returned to grinding, an adsorbent in the form of an abrasion resistant char added and agitated and the char removed by screening. The char may be partly returned to the agitation stage and partly used for recovery of the metal by incineration. The screening and agitation stages may be repeated, the char progressing in a counter current direction and the char concentrate removed at the first screening stage.  Four flow sheets are given illustrating such processes.  The apparatus may be a rotating screen with the pulp supplied internally at the bottom and the char removed internally at the top.

Inventor: CAMBAY CHARLES AMEDEE
IPC: B25B13/16
Filed: 1919-01-08
Abstract: 127,522. Cambay, C. A. Sept. 16, 1918, [Convention date]. Pliers; vices.-A double-ended adjustable spanner which may be used as a hand vice or tongs, comprises two symmetrical plates provided at their ends with jaw parts and slidably connected together by the interengagement of convex and concave parts on the plates, these parts being close to the jaws so as to give the greatest suppoit at the parts receiving the greatest strain. The plates are operated by a right and left hand screw and a spring tending to open the jaws is arranged between the plates, and a stop pin is provided to limit the travel of the screw to prevent accidental separation of the plates. Figs. 3 and 4 are sections on the lines A-B and C-D of Fig. 1, and Figs. 7 and 9 are opposite views, with the nearest plate removed in each case. The spanner comprises two similar plates 1, 2 formed at their ends with jaws 18, 19, 20, 21. The plates are formed adjucent the jaws with concave or undercut parts 25, 25<1>, 24, 24' forming guides for the convex parts 22, 22<1>, 23, 23<1>. The plates are provided with openings 3 to afford access to the actuating thumb piece 4 of a right and left hand screw 5, 6 engaging nuts 7, 8 which are mounted in housings 9, 12 in the plates. The nut 7 is held stationary between projections 10, 11 on the plate 2 and the nut 8 engages at one side against a projection 13 on the plate 1. A spring 15 is arranged between projections 16, 17 on the plates 1, 2 respectively and keeps the projection 13 normally in contact with the nut 8, but when the spanner is employed as tongs the jaws are moved together against the action of the spring 15. To prevent the screw 5 being screwed too far into the nut 7 and thus causing disengagement of the plates 1, 2, a stop pin 26 is inserted into the screw 5. The jaw faces may be provided with grooves to engage the opposite angles of a nut, thus permitting the use of the spanner as a box spanner.

Patent GB-431781-A (GB)
Title: A process and product for use in the surfacing of roads
IPC: C08L95/00
Filed: 1934-01-08
Abstract: A fluid mixture of tar and bitumen or pitch, for the surfacing of roads, adapted to be applied by the apparatus usually used for tar surfacing, is made by incorporating the bitumen or pitch in solid finely powdered frrm with the tar so as to constitute a p  stable suspension.  The subsequent solution of the bitumen or pitch in the tar is effected by heating to about 100 DEG  C.  This may be effected before the spreading on the road, or after spreading, e.g. by the heat of the sun.  To facilitate the powdering of the pitch or bitumen and to provide a filler, a substance such as chalk, silica, slate or coal may be added and the mixture ground together.  In an example 80 parts of coal are added to 20 parts of dry bitumen and the finely powdered mixture is incorporated with an equal amount of tar.  In another example, a solution of bitumen in a solvent having a boiling point below 100 DEG  C. is mixed with a paste of coal dust and water, and the solvent and water are driven off, the product being a dry granular or powdered mixture of coal and bitumen in the proportions of 85-75 : 15-25.  According to their fineness, the grains are incorporated as such with the tar or are first more finely pulverized.  The tar may be replaced by a petroleum oil.
