Title: An Apparatus for, and Method of, Manufacturing a Multi-Layer Shoe Part.
IPC: A43D11/02
Filed: 1966-05-07
Abstract: 1,150,271. Boots. GEBR. BIEDERMANN K.G. 12 April, 1966 [7 May, 1965], No. 15935/66. Heading A3B. In the manufacture of multi-layer shoe parts a concave mould 3 with a leather vamp held thereon by suction is first displaced along its longitudinal axis to a position below a press head 4, which is heated if a thermoplastic toe cap is to be used, and in which a switch pin 20 contacts a switch 22 and initiates a fluid operated piston and cylinder system. If a non-thermoplastic toe cap is to be used the vamp is coated with adhesive before the mould is moved under the press head. A piston 10 lowers a suction holder 5 causing a suction tube 29 to engage a toe cap 32 on a stack 31. The piston is retracted and a piston 13 moves the suction holder axially until it enters a bore 23 in the press head, the suction tube extending through an opening (25), Fig. 2 (not shown). The head 4 together with the suction holder is lowered by a piston 9 and the toe cap, preheated if it is thermoplastic, is forced off the tube 29 and into adhesive engagement with the vamp in the mould. A coupling 27 including a vertical slot 33 in which a shaft 28 of the holder 5 is vertically displaceable accommodates the vertical movement of the holder 5. The press head 4, holder 5 and mould 3 are returned to their starting positions, the vamp with the toe cap secured thereto is sprayed with adhesive by a spray gun 15 and a lining leather is applied to the adhesive surface. The mould 3 is moved under the press head which is lowered to press the components together. The head 4 is lifted and the mould returns to its starting position. It is possible to substitute hand or foot actuated operating means for at least some of the movements. Multilayer shoe parts other than fronts may be manufactured in suitably shaped moulds.

Abstract: 221,582. Watson, H. B., and Billetop, T. C. June 20, 1923. Casting soap &c. - Relates to machines for moulding and discharging semi-solid &c. substances, such as soap, wax, tallow, butter, lard, sugar compounds, glue, &c., of the type comprising a series of open ended moulds located in a common cooling tank through which a cooling- liquid is circulated, each of said moulds being fitted with a piston which, when the mould is being filled in its vertical position, forms the 'bottom of the mould, and which pistons are connected to a common operating part by which they can be moved to eject the moulded pieces. The tanks K<1> - - K<4> and the pistons therefore are mounted on a structure C, adapted to rotate upon a horizontal axis A, in diametrically opposed pairs on opposite sides of said axis, and the relative movement between the moulds and pistons is obtained by imparting radial movement, by means actuated by the rotation of the structure, to either the tanks or pistons, the other elements being fixed to said structure. In the form shown in Fig. 1, the tanks are slidably mounted in bars M<1>, M<2> fixed to the structure C, while the piston rods p<1> of the pistons are fixed to the longitudinal sides of said structure. Each tank is fitted with a pair of rollers R which, when the structure is rotated, by means of gear wheels E, G, engage with fixed cam surfaces S, S<1> carried by brackets S<1>. In operation, assuming the tank K<3> to be in its uppermost position, the moulds thereof are charged with the material to be cooled and moulded, and the structure is then rotated. When the rollers R on said tank engage with the cam S, the tank is moved vertically upward and the moulded substance is ejected by the fixed pistons. At the same tme, the moulds n the opposed tank F<1> are brought into a position for charging. The moulds in each tank are charged and discharged successively. In a modification, the respective pistons of two opposite sets are connected together and weighted so as to be operated by gravity during rotation of the structure.

Title: Process and apparatus for making ribbons of glass or similar thermoplastic materials by drawing
IPC: C03B15/02
Filed: 1966-04-12
Abstract: 1,137,161. Flat glass manufacture. COMPAGNIE DE SAINT - GOBAIN. 12 April, 1966 [12 April, 1965], No. 15993/66. Heading C1M. In a process for the manufacture of ribbons of glass or similar thermoplastic material by vertically drawing from a bath of molten material on each side of the plane extending along the length of the ribbon and through the line of draw there is provided at least one cooling unit comprising a plurality of surface elements arranged side-by-side along a line transverse to the direction of motion of the material, said surface elements being capable of exchanging heat with the material by radiation, and the cooling of the surfaces of the material is controlled by regulating individually the temperature of each of said surface elements. The surface temperature of each of the surface elements is maintained at a value of more than 0À3 times that of the surface of the ribbon of material. In the preferred embodiment for cooling a vertically drawn sheet of glass cooling units 8 are disposed on either side of the point of draw. Each unit 8 is formed from a tube having a single horizontal longitudinal separator 9 and a plurality of vertical partitions 13 dividing the lower half of the tube into separate compartments 12. Cooling air is separately and controllably fed into each compartment and is exhausted through ports 15. Coolers of conventional construction 7 may be located above the units 8, such coolers 7 each being supplied with its own controllable supply of cooling fluid (e.g. air or water). In other alternative embodiments cooling units are described comprising such as nests of parallel tubes with V-heads, and rectangular boxes subdivided into a plurality of compartments. Conventional coolers 7 may also be located between the cooling units and a glass ribbon being drawn. The surface elements of the cooling units may be so designed that a temperature gradient can be established between the outer and inner surfaces of each. This may be achieved by making those parts facing the glass ribbon of a relatively poor conductor of heat but which will withstand the operating temperatures, for example of cement or a plastics material. Alternatively, the surface elements may contain an inner wall, the space between which and the wall facing the ribbon being filled with an insulating material, or they may be double-walled, thus enclosing the cooling fluid with another fluid, e.g. air. The cooling fluid may be a liquid having a high boiling-point.

Filed: 1943-09-30
Abstract: Natural rubber including guttapercha, and synthetic rubbers are cured by a process which comprises heating them with a quinone dioxime ester of an aromatic or substituted aromatic acid in the presence of an oxidizing agent.  The preferred esters are paraquinone dioxime-benzoate, -m-nitrobenzoate, -di (m-nitrobenzoate), -p-chlorobenzoate and -di (p-chlorobenzoate), though any of the esters of quinone dioxime, thymoquinone dioxime, naphthoquinone dioxime and anthraquinone dioxime with alkyl benzoic acids, mono or poly nitrobenzoic acids, mono or poly chlorbenzoic acids, hydroxybenzoic acids and thiosalicylic acids may also be employed. Preferably from 0.2 to 10 parts by weight of the ester to 100 parts of the rubber is used together with up to 25 parts of the oxidizing agent which may be lead peroxide or red lead.  The synthetic rubber may be polybutadiene, polychloroprene, an interpolymer of butadiene with acrylonitrile or styrene, or a low temperature interpolymer of an iso-olefin with a diolefin such as that described in Specification 523,248, [Group IV].  The curing agents are preferably added to the rubber while it is in the solid state or in solution in benzene or paraffin naphtha; curing being preferably effected at 75 DEG  to 175 DEG C. for a period of 5 to 60 minutes.  Examples are given illustrating the superiority as regards freedom from scorch of aromatic quinone dioxime esters over paraquinone dioxime when these compounds are added separately to similar mixes containing different rubbers and substances chosen from lead peroxide, red lead, sulphur, zinc oxide, stearic acid, carbon black and softening oil.  Clay and pigments may also be added. Specification 475,034 also is referred to.

Title: A method for substituting alkyl groups in the aromatic nucleus
Filed: 1927-06-16
Abstract: 288,122. Verley, A. March 31, 1927, [Convention date]. Alkylated aromatic compounds.-Aromatic compounds are alkylated by means of a. mixture of an alcohol and sulphuric acid containing alkali pyrosulphate. Sodium or potassium pyrosulphate is dissolved in commercial sulphuric acid, alcohol is added whereby alkyl sulphuric acid and alkali bisulphate are formed, and this mixture reacts with aromatic hydrocarbons, halogen substituted hydrocarbons, phenol ethers, ethers, aromatic acids &c. Thus with phenylacetic acid an alkyl group is introduced in the para position. To obtain alkyl derivatives of free phenols a previously prepared monosulphonated derivative of phenol is used, thus when phenol-p-sulphonic acid is acted on by a mixture of sulphuric acid, pyrosulphate and methyl alcohol the o-methyl derivative is obtained, and the sulphonic group is removed giving o-cresol. By using m-cresol and isopropyl alcohol, thymol is obtained. In examples (1) toluene, isopropyl alcohol and sulphuric acid containing sodium pyrosulphate are agitated together and the temperature allowed to rise. The product is treated with water and the upper layer drawn off and washed and separated by fractionation into p-cymene and toluene; (2) benzoic acid, methyl alcohol and sulphuric acid containing sodium pyrosulphate are heated and agitated, on treating the product with water a layer of m-toluic acid and its methyl ester is obtained, and these are, separated in known manner.

Abstract: 549,781. Oil engines; reversing. HARPER, W. A., and REBBECK, Sir F. E. Dec. 13, 1941, No. 16121. [Classes 7 (iii) and 7 (v)] In a two-stroke multi-cylinder engine having a reciprocating fuel pump to each cylinder, the pump plungers are actuated by the engine driving mechanism through a link and rocking lever. Fig. 1 shows three cylinders 1, 2, 3 of an engine having fuel pumps 1F, 2F, 3F actuated by levers B connected to the crossheads A of the eccentric gears 7, 9 driven by the pistons which serve to control the exhaust. In order to time the injections rightly in relation to the pump deliveries, the fuel pump of one cylinder is driven from the driving-mechanism of the exhaust piston of another cylinder ; thus the pumps 1F, 2F, 3F are arranged to supply the cylinders 3, 1, 2 respectively. Three more cylinders and fuel pumps may be similarly arranged. The timing of injections may be further adjusted by mounting the levers B on eccentric fulcra E, Fig. 4, adjustable by means of screws J, which may be connected for simultaneous actuation. In a reversing engine, the connections between the pumps and cylinders are altered, for running astern, by means of valves, and the eccentric mountings of the levers B are also adjusted to alter the timing for the reverse drive. In doubleacting engines the fuel pumps are driven from the members connecting the exhaust pistons at the two ends of the cylinders, and in order that all the fuel pumps may deliver fuel on the upward strike, the levers B for driving the pumps for one end of the cylinders have their fulcra E at one end, and the connections to the pump plungers intermediate of the levers.
