Title: Method of and apparatus for moving groups of cylindrical objects  each of which receives a rotary movement
IPC: F27B9/14
Filed: 1974-07-19
Abstract: 1452584 Feeding objects through furnaces COMMISSARIAT A L'ENERGIE ATOMIQUE 19 July 1974 [7 Aug 1973] 32149/74 Heading F4B Cylindrical objects for treatment are fed in succession through a furnace, stove or the like having parallel facing walls 3, 4, the objects being arranged in two groups 2a, 2b, one in contact with one wall, the other in contact with the other, each object during movement through the furnace rolling against the wall and against two objects of the other group. The walls may be vertical or oblique, the movement being obtained by gravity. Alternatively, at least one of the objects may be rotated by mechanical means and the walls may then be horizontal. In the form shown the bottom cylinder 5 is raised and lowered by a cam mechanism, there being spaced toothed racks at each end engaged alternately by gears on the ends of the cylinder shaft. As the cylinder descends the gears engage one of each pair of racks to rotate the cylinder in one direction. As the cylinder rises, it moves into contact with the opposite wall and the gears engage the opposite racks so that the cylinder, in both movements, rolls on the wall with which it is engaged. When the cylinder 5 is at its lowermost position the pusher 9 pushes the adjacent object with the outlet passage 10, the following objects being retained by catch 8.

Title: Method for marking rubber articles
IPC: B44C1/17
Filed: 1936-11-24
Abstract: Indiarubber articles are decorated by applying thereto a transfer having the design in an ink prepared with a basis of indiarubber and containing ingredients rendering it readily vulcanizable, subjecting the article to vulcanization while the support for the transfer is still in place, and then removing the transfer; alternatively, the inscription can be printed directly on to the article with an ink containing indiarubber and vulcanizers.  The design may be printed or stencilled on the support, preferably paper, or the support may be completely covered and the design formed by cutting or otherwise shaping. The support may be provided with a coating of cellulose acetate, vinyl resin, benzyl cellulose, or the like dissolved in acetone, benzene, or ethyl alcohol to prevent it from sticking to the article during vulcanization.  According to an example, the ink may consist of indiarubber, zinc oxide, magnesium carbonate, titanium white, colouring-matter, sulphur, a vulcanizing accelerator, and xylol.

Dec. 21, 1925, Lasting and pulling-over.-A step by step lasting machine of usual form is provided with a member which can be interposed between the tack driver and the upper, at the operator's will, so that shoes having the margins of the lasted uppers secured to the insoles by cement may be tacked at desired portions, and where not tacked the driver will give a blow to the member after the usual pulling-over and wiping, so that the cemented margins are firmly pressed together. The parts added to the usual machine comprise a slide 6 normally retracted by a spring 7 but held in advanced position when desired by a pawl 10. The pawl is actuated by a trip member 8 pivoted to the slide 6 and adapted to be engaged by a finger 13 secured to a pinion gearing with a segment 16 provided with a handle 17. A member 5 is carried by the slide 6 and, as shown, is positioned under the driver 3. In this position, the normal tack-driving blow of the member 3 is converted into a thrust acting on a substantial portion of the upper margin. Specification 19965/10 is referred to.

Title: Improvements in or relating to the polymerisation and copolymerisation of butadiene
IPC: C08F36/06
Filed: 1956-10-24
Abstract: Butadiene is polymerized alone or copolymerized with styrene in the presence of metallic lithium and/or a lithium hydrocarbon and in the absence of oxygen or oxygen-containing compounds. Metallic lithium is used as a finely-divided dispersion in petroleum jelly, a mineral oil or paraffin boiling above 200 DEG  C. Suitable hydrocarbon lithiums and polylithiums including various alkyl, aryl and aralkyl lithiums and polylithiums of which a large number are specified.  The amount of catalyst may be such as to provide 0.001 to 1.0 gram as lithium element per 100 grams of monomer.  Temperatures from 0-100 DEG  C. can be used.  Liquid or vapour phase polymerization is used depending on the temperature and pressure and bulk or solution technique may be used, suitable inert solvents being pentane, hexane, heptane, petroleum ether, benzene, cyclopentane, and cyclohexane.  Oxygen, other components of air, and water should be avoided, e.g. by charging the reactants under helium or argon, venting about 10 per cent of the charge and sealing the reactor.  Also the monomers and solvents should be pure, and are preferably given a final purification by passing through a silica gel column.  The catalyst is preferably added last.  The reaction product is immersed in methanol or isopropanol containing an anti-oxidant which destroys the catalyst, precipitates the polymer and incorporates the anti-oxidant. Specification 603,630, [Group XIII], is referred to.

Abstract: 1,195,223. Projection copying. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 18, 1967 [July 20, 1966], No. 32486/66. Heading G2A. A primary pattern in the form of a transparency 5 is mounted on a carriage 3 which moves along a guide 12 past a fixed plate 1 having a slit 2. As the transparency moves past the slit, a lamp 14 causes an image thereof to be projected strip by strip on to a photo-sensitive film 7. The film 7 is mounted in a carriage 4 which moves along a guide 13. The two carriages 3, 4 are linked by a bar 10 pivoted at 11, so that they move in opposite directions at relative speeds determined by the position of the pivot 11. The pivot can be moved progressively towards carriage 3, so that a progressively increasing linear magnification on the film 7 is produced. The arrangement may thus be used to prepare a master negative for the manufacture of the printed scanning coils of Specification 1, 157, 805.

Abstract: 424,709. Looms with stationary weft supplies. GABLER, J., 161, Rheinstrasse, Ettlingen, Baden, Germany. Nov. 22, 1933, No. 32606. Convention date, Nov. 22, 1932. [Class 142 (ii)] Relates to the production of strong edges, resembling centre selvages, in fabrics woven in looms wherein the weft is drawn in loop form to the centre of the shed, and, after being cut, is drawn through the shed as a single thread. The weft 2 as laid in the shed is held between the reed 7 and a reciprocating holder 6 on the temple support 8. A support 13 for thread bobbins 14, 15 is then rotated by a Maltesecross gear 20. The threads 16, 17 from the bobbins are thereby twisted to bind the weft, and they form the warps at the edge of the fabric. The bobbin support is provided with springs to take up slack in the threads. The weft ends projecting from the edge of the fabric are straightened by their engagement with roughened feelers 24 which reciprocate in the direction of the weft. The weft ends and the edge of the fabric then pass through a slotted guide 28 acting in conjunction with a rotating cutter 27, whereby the weft ends are cut off at a distance from the edge of the fabric determined by a part 29 of the guide through which the slot does not extend.

In the production of lamp bulbs, filaments are fed upwards by vibrating bowl 1 till they are positioned at position A within arm 9. From position A they are released by rotary reciprocation of the arm to fall down shoot 20 in which they are retained by arm 26. From shoot 20, a filament is released by rotation of arm 26 to fall down shoot 21 and be retained by arm 27. From shoot 21 the filament is released into shoot 22 by rotation of the arm 27. The filament is released from shoot 22 by the pivoting of arm 28 to allow it to fall on to arm 45 which pivots clockwise about 47 to drop the filament on to a tooth of wheel 2 for discharge thereby. In this way reserve filaments are provided. The rotation of arms 26, 27 and 28 are governed by solenoids 29, 30 and 31 which are included in an electric circuit such that a filament is always ready and available to be discharged by the arm 28.
