IPC: C25D1/10
Filed: 1929-02-07
Abstract: 330,501. Thorogood, R. P., and Good, J. Feb. 7, 1929. Records, duplicating; ribbon records.-A metal matrix in ribbon form for use in the manufacture of sound records is made by electrodeposition on to the face only of the master record f, which is also of ribbon form and is wound helically in a long length around a carrier b with its convolutions spaced apart. The record ribbon f is wound in a helical groove e which is formed in the surface of the carrier b, and a rubber &c. cord g may be wound between and over the edges of adjacent convolutions of the ribbon, as shown in Fig. 3. Alternatively, the carrier b may be of non-conducting material and have a helical rib for separating the convolutions of the ribbon f. The carrier b, of hollow cylindrical form, and an anode c, arranged around the carrier, are supported within a vessel a containing -the electrolyte. The anode c may be of tapering form and, to avoid voltage drop along the conducting surface of the ribbon f, a metal strip connected with the negative pole of the source of current supply is provided with a number of tongues, adapted to bear against the said conducting surface at different points along its length. The carrier b may be rotated by means of a belt-driven drum m, and the ribbon f may be formed of a metal adapted to serve as a cathode, or it may be coated with graphite &c. Duplicate sound records are produced from the matrix ribbon by pressing the latter, under heat if desired, with a plain ribbon of celluloid &c.

Abstract: 860,322. Laminating. NEWCOMB, R. K. Feb. 5, 1959 [Feb. 10, 1958], No. 4137/59. Class 140. [Also in Group XVI] A machine for laminating two webs or a web and a succession of sheets comprises a pair of rolls A and B with substantially parallel axes one above the other and urged together to form a substantially horizontal nip, means for rotating the rolls, means for feeding a web I around one of the rolls and into the nip, a table or other support means 25 leading into the nip to guide the other web or the sheet H into the nip, a reservoir for a liquid adhesive formed at the entrance to the nip between the two webs or the web and sheet, and dams E at the sides of the two webs or web and sheet, or part thereof to be coated to close the ends of the reservoir, whereby as the webs or web and sheet are drawn into the nip, the liquid adhesive may be coated evenly and thinly over the adjacent surfaces of the two webs or web and sheet. As shown, an endless belt Q, e.g. of PTFE, passes over the table 25 and carries the sheet or web H into the nip, and the laminated product from the web through the nip between the rolls M and N of a second pair. The apparatus is driven from a motor J and the product wound up at P. The faces of the dam are shaped to conform with the faces of the roll A and the table 25. The surface of one of the rolls A and B, e.g. the lower, may be of resilient material, e.g. rubber or neoprene. In place of the belt Q, a sheet of cheap newsprint or kraft paper may be used to carry the sheet or web H into the nip and rolled up separately on emerging from the apparatus, or a continuous backing web may be used which forms part of the finished laminate. The web I may be a transparent film of a cellulose ester, e.g. the acetate, polyvinyl chloride or copolymers thereof, polyesters, polyamides or a combination thereof, and a second like web may be used on the other side of the laminate. The other web or sheets may be of paper and may be printed. The adhesive may be latex or an emulsion or solution of vinyl polymers or copolymers, vinylidene chloride copolymers, synthetic rubbers, acrylic ester copolymers and mixtures thereof, natural gums, ester gums and mixtures of two or more of these. When the second web or sheet is printed paper, if it is peeled off a few moments after laminating to the first web, the image is transferred, and a positive transparency may be obtained which may be used for quick processing of lithographic plates.

C. engine and timing the ignition pulse in each cycle comprises an inductive pick-up associated with the spark-plug lead to the first cylinder, feeding the induced pulses to an averaging circuit for determining RPM and to stroboscopic apparatus incorporating means for altering the phase of the light pulses by a measured amount to make them coincide with top dead centre, the phase change corresponding to the angle of advance. The handheld unit shaped like a gun and incorporating a stroboscopic flash-tube and a meter, is directed at timing marks on a scale attached to the engine and includes a knob operating a switch 32, Fig. 6, and the slider of a potentiometer 40. With switch 32 open, the leading edge of each pulse induced in pick-up 22 is fed via transistors 84, 86 to a monostable multi-vibrator comprising transistors 88, 90 to change its condition, simultaneously blocking transistor 86 to prevent spurious pulses from affecting the multi-vibrator. The uniform pulse output from the multi-vibrator is fed via transistor 81 to an averaging circuit 15 and RPM meter M. The leading edges of the multi-vibrator pulse output are also fed via line 101 to actuate the stroboscopic flash-tube, whereby the timing of the ignition pulses is indicated on the scale attached to the engine. With switch 32 closed, relay 34 is energized to change over switches 76, 78, 94. The duration of the pulse from the multi-vibrator is now determined by potentiometer 40 which is adjusted so that the stroboscopic flashes, now coinciding with the trailing edges of the multi-vibrator pulses, occur when the engine is at top dead centre. The averaging circuit 15 measures and indicates the pulse width corresponding to the angle of advance or retard.

Abstract: Catalysts are prepared by combining with or applying to a preferably porous carrier, a metal compound bonding substance capable of adsorbing water vapour and/or organic vapours, drying and applying a catalytic material in powder form in an atmosphere containing water vapour and/or organic vapours.  Alternatively, the powdered catalytic material may be applied to the dried carrier containing the bonding substance in the presence of an amount of water and/or organic liquids so limited as to be completely adsorbed by the catalytic material without affecting the powdery nature thereof.  The dried carrier containing the bonding substance may itself be catalytic, and its efficiency is improved by the subsequent treatment with the additional catalytic material in powder form.  Before or after the application of the powdered catalytic material, the carrier containing the bonding substance may be treated with a mixture of hydrogen chloride and oxygen at elevated temperature or by heat alone.  The bonding material is applied to the carrier by impregnation with or precipitation from solutions or the bonding material and carrier may be coprecipitated.  The catalytic material may be a metal, metal oxide or other metal compound or mixture thereof, and the metal of the catalytic material may be the same as or different from that of the bonding substance.  The carrier may be metallic or non-metallic.  Numerous examples are given.  The catalysts are suitable for oxidation, chlorination, hydrogenation, dehydrogenation, cyclisation, addition, hydration and alkylation reactions.

Abstract: 1,171,339. Thermal storage space heaters. WITTE HEIZTECHNIK G.m.b.H. 2 Feb., 1967 [3 Feb., 1966], No. 5032/67. Heading F4U. In a thermal storage space heater, the peripheral measurement of the transverse crosssection of an air flow path through or adjacent the storage core increases in the direction of air flow. As illustrated, a fan 4 blows air into the core 2 through a passage 15, the air leaving the core through passages 16 and 17. The combined peripheral measurements of the outflow passages is thus approximately twice the corresponding measurement of the inflow passage, and, in the illustrated construction, the outflow crosssectional area is greater than the inflow crosssectional area. In other constructions, the outgoing air flow may contact core walls of zig-zag section and there may be more than one inflow passage.
