Title: Improvements in tile-making machines
IPC: B28B3/20
Filed: 1934-12-21
Abstract: 449,397. Extruding tiles &c. PORTER, E., 154, Chilton Road, Bridgwater, Somerset. Dec. 21, 1934, No. 36649. [Class 87 (ii)] Relates to machines for extruding tiles and bricks wherein the die aperture is of a crosssection which includes all projecting portions of the articles and is blocked periodically to modify the cross-section of the issuing clay ribbon. In the form shown in Fig. 6, for making tiles of the kind shown in Fig. 1 and described in Specification 434,389, [Group X], the roll portion 9 is formed by an unobstructed part of the die opening 12. The roll 9 is caused to merge by a tapered part. 9<a> to a flat part of the tile by sliding shutters 13, 14. The buttons 10 are formed by the temporary lowering of slides 31. The operation of the blocking devices is effected through linkage operated from friction rollers driven by the passage of the moulded clay ribbon. The ribbon is severed to remove narrow strips including button ridges 10 and the commencements of the roll portions 9 by C-arms carrying wires adapted to be lowered to effect 'the cutting and to move simultaneously with the same speed as that of the issuing ribbon. In another form, a tile having a flat-sided projection is formed by horizontally moving shutters adapted to block the die opening. In another form, a tile of the kind shown in Fig. 11, is formed by extrusion through a die having one edge of its opening provided with a reciprocating shutter to produce the undulations 54. In the machine shown in Fig. 14 for making bricks, the frogs 62 are produced by a reciprocating member 59 adapted to block the die opening 58.

Abstract: 892,955. Photographic cameras. GAUTHIER G.m.b.H., ALFRED. Oct. 29, 1959 [Jan. 31, 1959], No. 36690/59. Class 98(1). [Also in Group XL(b)] In a photographic camera in which coupled aperture and exposure time setting members providing combinations of aperture and exposure time with uniform exposure gradation may be coupled to either manually or photoelectrically actuated setting members, allowance is made for film sensitivity and locking means are provided to prevent incorrect adjustment. Cams 4d and 31c on the photo-electric and manual setting members 4, 31 when in their starting positions, shown in Fig. 1, disengage rods 21, 36 from the film speed setting member 5. The film speed is set by pressing an engaging member 18a to release a detent 18b, 19 and the connection between the aperture and exposure time setting members 1, 2 and a transmission member 32. Index 27a is then appropriately set on the scale- 20 and member 18a released. Manual or automatic setting is selected by a lever 61 which connects transmission member 32 alternatively with setting member 4 or 31 through a bar 34. Locking members 68a, 63b, 63c, and 63d, 31d prevent actuation of lever 61 except when members 4 and 31 are in their starting positions. The setting and transmission members may be annular. Automatic settings. On actuation of the camera release an engaging -member strikes a pawl 76 which releases the member 4. The member 4 is driven by mechanism 4b, 14. An abutment 16 releases a pin 17 and a lever 12 clamps the moving coil of a photo-electrically controlled meter. A lever 10 senses the position of a cam on the moving coil and positions a lever 11 to arrest member 4 in a position dependent upon the incident light intensity. Manual settings. Member 31 is adjusted until pointer 31e is on the appropriate mark of a scale (not shown) on member 5. For flash light photographs a scale 71 or a pair of scales for computing light intensity from flash bulb type and range is or are used. Warning device. Film speed setting member 5 also controls the position of cams 48, 148 which position markers 46, 47 in the field of view of the camera. A pointer 42a on the moving coil meter is also visible and provided it lies between the markers an automatic exposure can be made.

Patent GB-345239-A (GB)
Title: Improvements in the production of coloured synthetic rubber
IPC: C08J3/20
Filed: 1929-12-16
Abstract: The process of the parent Specification is extended to the colouring of synthetic rubber by incorporating the colouring components with dispersed (dissolved or emulsified) intermediate products in the production of synthetic rubber from diolefines such as butadiene and isoprene, converting the colouring components into insoluble colouring materials and then carrying out the production of solid synthetic rubber in known manner.  The colouring materials may be vat, sulphur or developed dyes or lakes which may be added as in the form of leuco compounds, soluble salts, soluble modifications or soluble components.  The polymerization of the diolefines may be carried out by warming, if desired in the presence of a small amount of an alkali metal catalyst such as sodium until practically solid but still further polymerizable products are obtained.  The products are then dissolved in organic solvents such as benzine, cyclohexane or liquid aromatic hydrocarbons or emulsified in water or other liquid having no dissolving action on the polymerization product, if desired with the addition of a dispersing agent such as oleic or Marseilles soap.  After the precipitation of the colouring materials the products are further polymerized in any convenient manner and if very large quantities of colouring materials have been used the final products may be used for colouring further quantities of solid natural or synthetic rubber.  In examples (1) the viscous liquid obtained by the polymerization of butadiene in the presence of sodium is dispersed in a solution of butylated naphthalene sulphonic acid and incorporated with a solution of Indanthrene blue 2GS, caustic soda and hydrosulphite in water. The polymerization is completed and the leuco compound of the dye oxidized by air, (2) Isoprene is emulsified with olein, Marseilles soap and water and polymerized with hydrogen peroxide.  A solution of Ponceau 3R in water is incorporated and then barium chloride is added and the polymerization finished with more hydrogen peroxide. (3) Kyrogene Black TGO is vatted with sodium sulphide and water and incorporated with the emulsion of polymerized isoprene produced in the foregoing example and air is blown into the mixture to completely precipitate the dye.  The emulsion is broken with alum and the paste formed is washed and dried.  On vulcanizing a rubber compound from the dried paste black sheets of rubber may be obtained.  (4) Naphthol AS dissolved in caustic soda and Turkey-red oil is added to the emulsion prepared as in example 2 and a solution of diazotized 3-nitro-4-toluidine is added.  The product may be used in colouring rubber, guttapercha or balata. Specification 246,817, [Class 2 (iii), Dyes &c.], is referred to.
