Title: Apparatus for the registration of pieces of material prior to feeding them to a sewing machine or other working machine
IPC: D05B33/02
Filed: 1939-03-23
Abstract: 526,640. Feeding sheets; delivery apparatus. MELZER, E., and SIEGMUND, H. March 23, 1939, No. 9224. [Class 100 (i)]  Pieces of material are registered, prior to feeding to a sewing or other machine, on a table having abutment rails on two contiguous sides, the material being deposited on a sliding plate by a suction gripper and then moved against the abutment rails. The table 2 is supported on vertical posts 43 slidable in bearings 6 and is normally flush with a plate 12 which surrounds the table on three sides and along two adjacent sides has flanges 13, 14 against which the pieces of material are registered. The pieces are taken from a box or a number of boxes by a suction gripper 16 which transfers them to the table 2. A smooth plate 27 movable on inclined horizontal guides 28, 29 is then situated over the table and receives the material. The plate is withdrawn and owing to its movement in an inclined path causes the sheet to be moved up to the guides 13, 14. The flange 14 is made smoother than the plate 27 so that the lesser friction ensures that the material will not stick to the flange and so not move up to the flange 13. The plate 27 is reciprocated by crank discs 42, 43 and has inclined slots 48, the flanges being slotted to receive the remaining tongues. The table top and sliding plate may be inclined.

Abstract: 1520172 Laminates HONNY CHEMICALS CO Ltd 8 March 1976 09242/76 Heading B5N In a process for bonding rubber to a ferrous metal substrate, copper is deposited on the substrate followed by an adhesive layer comprising an interpolymer derived from 40 to 99% of one or more conjugated dienes, from 1 to 45% by weight of one or more vinyl-substituted heterocyclic bases and from 0 to 40% by weight of one or more additional copolymerizable monomers, contacting the adhesive layer with a curable rubber composition and uniting the rubber with the substrate by the application of heat and pressure. The copper coating may be applied by electroless plating, e.g. by dipping or by electroplating. Many suitable dienes and additional monomers are specified, the heterocyclic bases being preferably of the pyridine, quinoline and isoquinoline series containing only one CH 2 =C< substituent and the rubber may be natural rubber, polybutadiene, polyisoprene, a copolymer of butadiene with styrene or acrylonitrile, or polychloroprene. The substrate. may be in the form of wire, the process being applicable in the manufacture of steel reinforced tyres, belts and hoses.

Title: Improvements in adhesives and coating compositions
IPC: C08L61/24
Filed: 1941-07-23
Abstract: 551,404. Improved adhesive and coating compositions. DEARING, W. C. July 23, 1941, No. 9282. Convention date, July 18, 1940.. [Class 2 (iii)] A. stable dry mixture adapted to form on addition of water an adhesive or coating composition comprises a urea-formaldehyde resin and an ammonium salt of a non-volatile acid, a 1 per cent. solution of which acid has a pH not greater than 4. Specified ammonium salts are the sulphate, dihydrogen phosphate, oxalate and diammonium hydrogen phosphate. In preparing a dry mixture for use as a water paint the pigment may be mixed with the resin by grinding but preferably is dispersed in an aqueous solution of the resin which is then dried, e.g. in a spray or vacuum drum drier. Before evaporation a plasticizer, e.g. ethylene glycol, may be added. The mixture may be prepared simply by mixing fine crystals of the ammonium salt with the resin. The proportion of salt is that which will cause the resin to harden with the desired rapidity after the addition of water. A suitable resin is obtained by heating one mol. of urea with 2 mols. of formaldehyde (37 per cent.) which has been brought to pH 4.5-5.5 with caustic soda. In examples, an adhesive is made by mixing 1 part of dry ammonium sulphate with 100 parts of the dried urea-formaldehyde reaction product, and a paint by evaporating a dispersion of 100 parts titanium oxide pigment and 1 part of ethylene glycol in an aqueous solution of 100 parts of urea-formaldehyde reaction product and mixing 1 part of ammonium sulphate with 200 parts of the spray-dried product.

Abstract: 511,305. Centrifugal pumps. GILKES & GORDON; Ltd., G., and JACKSON, E. A. March 26, 1938, No. 9304. [Class 110 (i)] A centrifugal pump is primed by setting the runner in rotation, establishing a water seal on the outlet side of the pump, by hand or automatically, due to the rotation, and then exhausting the air space between the seal and the static liquid level of the supply. Fig. 2 shows one arrangement using a primary pump 9, preferably of the water-ring type, having its inlet 10 coupled to the inlet 2 of the main pump, sucking air from the pipe 2, and delivering it through a pipe 11. Sealing water is supplied to a gland 13. Valves may be used in the connections to the pump 9 and the pipe 14 may be led where desired. In another arrangement the priming pump is located within the casing of the main pump, the two runners having a common shaft. An additional water supply pipe leads from the main pump delivery to the inlet of the priming pump. A further modification in which the main pump delivers axially, has the priming pump arranged in the casing adjacent the water seal. The latter pump may have a double runner. Where the main pump is of the double-entry type, the suction of the priming pump is devided and connected to the two inlets. Alternatively the impeller disc of the main pump may be perforated so that air can pass through it. The invention may be applied to all types of centrifugal pumps.

Title: Method of and apparatus for the continuous preparation of solid or semi-solid emulsions
IPC: B01F3/08

Abstract: 569,731. Food fats. ZARECKI, Y., and PALESTINE OIL INDUSTRY SHEMEN, Ltd. June 15, 1943, No. 9597. [Class 84] [Also in Groups II and III] In making solid or semi -solid emulsions, the liquid forming the continuous phase is initially introduced and continuously fed into a closed vessel having an adjustable outlet at the top, the liquid forming the discontinuous phase is continuously introduced under pressure, and the emulsion separating about the mixed liquids is uninterruptedly forced out of the vessel, by the pressure of the liquids therein, the rate of withdrawal of the emulsion and the pressure in the vessel being regulated by adjustment of the outlet. In the manufacture of margarine, for example, water cooled to 2-3 C. is forced into vessel 1 through-nozzles 6, and fat warmed to 45-48 C. is forced in through nozzlers 7 under a pressure of about 7 ats. The temperature in vessel 1 is regulated by withdrawing water, through cock 12 and recirculating it after cooling and the pressure therein is maintained, at about 2 ats. Emulsions rising to the top of the vessel is formed into a compact mass and has excess water removed by means of a rotary worm conveyer 16, and is forced out through tapered outlet 4. ln normal operation, water byepassed through pipe 21 rotates a blade wheel 19 to maintain open an electric circuit, but if the emulsion accumulates in the vessel to such an extent that the rotation of the blade wheel is stopped, the circuit is closed to: operate a lamp or bell.

Void [Abridged as open to inspection under Sect. 91 of the Acts, April 3, 1932]. [Class 40 (v).] In a push-pull amplifier, differences between the operating characteristics of the two valves 1, 2 are compensated by using a voltage derived from the output current of each valve to vary its amplification for different values of input potential. The signals are applied to the grids 7, 8 in phase opposition by a transformer 13, and each grid is individually biassed by batteries 16, 17, to balance the amplifier under no-load conditions in the region of small anode current, and by resistances 25, 26, through which the anode current flows, to superimpose an additional bias to equalise the plate currents when signals are being received. According to modifications, the compensating voltages are applied to the plates 3, 4 are algebraic parts of the total plate voltages, or to the screen grids, when such valves are used.

A method of malting grain involves steeping the grain in water until it has a water content of about 38 weight percent; allowing the steeped grain to partially germinate; re-steeping the partially germinated grain in water, thereafter aerating the grain produced with an oxygencontaining gas, and repeating the re-steeping and aeration at least once to produce a steeped grain having a water content of at least 48 weight percent; and allowing the grain having a water content of at least 48 weight percent to germinate further. Grain possessing this last water content may be re-steeped or subjected to a gas (carbon dioxide) or gas mixture poor in oxygen.
