Title: Improvements in the manufacture of granule-coated webs
IPC: B24D11/00
Filed: 1936-06-19
Abstract: 476,959. Granule - coated webs. TENNANT, W. J. (Carborundum Co.) June 19, 1936, No. 17130. [Class 60] In making granule-coated webs, the web passes. from the place at which adhesive is applied to that at which the granular material is applied through a chamber in which the atmosphere is regulated to control the condition of the adhesive coating. The controlled atmosphere may serve to maintain the adhesive in unchanged condition or to convert it into a suitable condition for receiving the granules, e.g. by altering its viscosity. As shown in Fig. 1, a web P passes over idler rolls 2, 3, 4, receives adhesive such as glue from roll 5 and then enters a chamber A in which the temperature is controlled by heating elements 11 which may be steam pipes or electrical heaters and the humidity is regulated by the introduction of water vapour from nozzles 12 of a supply pipe 13. Circulation of the air is maintained by a fan 14. After leaving the chamber a granular material is projected upwardly on to the downwardly facing adhesive surface of the web P in known manner. In a modification the granules are dropped on to the upper adhesive surface of the web. In a further modification shown in Fig. 3, the adhesive is applied by means of automatically controlled spray nozzles 27 in the chamber B and the desired vapour pressure is maintained by the evaporation of solvent contained in a vessel 29 provided with heating elements 30. If desired, further heat may be supplied by elements 31. Condensed solvent is removed by a drain 32. When water - soluble adhesives are used the spray nozzles are operated by warmed and humidified air and in the case of adhesives such as resin, lacquer or varnish, air laden with solvent, e.g. alcohol, acetone or benzol, is preferably used. Specifications 455,639 and 457,333 are referred to.

Abstract: 901,264. Corrugating sheet materials. CHLORIDE ELECTRICAL STORAGE CO. Ltd. May 10, 1961 [May 17, 1960], No. 17347/60. Class 87(2). In the manufacture of ribbed separators for electric accumulators resin impregnated sheet material 13 is formed with ribs 13a by passing it between a smooth, stationary strip 12 and a series of transverse laths 7 forming a part of an endless conveyer 6. Pressure from spring loaded plates 15, 15a and acting through a pad 17 on the strip 12 prevents longitudinal movement of the sheet 13 relative to the laths so that, as the spacing of adjacent laths reduces on entering the straight run, excess material is trapped and squeezed in the grips to form solid ribs 13a. The ribbed sheet is passed through two curing ovens before being cut. The sheet material may be impregnated with phenolformaldehyde. Specification 824,025 is referred to.

Title: Improvements in the refining of fatty glycerides
IPC: C11B3/06
Filed: 1951-07-23
Abstract: In the alkali-refining of fatty glycerides, either by a batch or a continuous process, an aminocarboxylic acid having, per basic nitrogen atom, more than one carboxyl group in alpha position thereto is added, to prevent neutral oil from becoming occluded by the soap stock formed.  From 0.075 to 1 per cent. of additive, based on the weight of glyceride, is preferred, and may be added to the glyceride or aqueous alkali before mixing, during mixing or to the mixed components.  The preferred compounds contain more than one carboxyl group linked through a -CH2- group to the nitrogen atom. Ethylenediamino-tetra-acetic acid is particularly preferred. Other compounds include trimethylamine tricarboxylic acid and N-alkyl or N-aryl imino-diacetic acids.  Either the free acid or its neutral or acid salts (e.g. of sodium, potassium or ammonium) may be used.  The alkali is preferably sodium hydroxide, but sodium carbonate or tri-sodium phosphate may be used.  It is preferred to inject up to 2 per cent. of its weight of steam into the glyceride before it is mixed with the alkali.  Specification 687,843 is referred to.

Abstract: 1481275 Data transmission INTERNATIONAL BUSINESS MACHINES CORP 28 April 1975 [17 June 1974] 17468/75 Heading H4P The handling capacity of a serial loop data transmission system is doubled by sending data around the loop in both directions. As shown, a single cable 20, constituting a transmission loop, is connected to a loop controller 22, e.g. a computer, which places both clockwise and counter-clockwise data flows on the loop. Regenerative repeaters such as 26a, 26b in the loop each connect respective pairs of terminals such as 24a, 28c to the loop, and each includes a first directional coupler for coupling one of the associated terminals with the clockwise data flow and a second directional coupler for coupling the other associated terminal with the counter-clockwise data flow. The directional couplers may be of the strip line type, and the regenerative receivers may be provided with "wrap-control" circuitry whereby the loop controller 22 can determine, in the event of a failure, where there is a break in the loop by successively signalling the different terminals. Suitable logic arrangements for the regenerative receivers and the wrap control circuitry are described with reference to Figs. 3 to 5 (not shown).

Open-tray burners; air supply; flame spreaders and deflectors.-An oil burning heater for brooders is constructed with means for deflecting warmth to the lower portions of the brooding space and for preheating the combustion air which travels a tortuous path to the burner. Beneath a metallic base member 1 is mounted a dish-like member 3 secured to the base member by bolts 4 leaving a space 6 between the upper edge 3<1> of the member 3 and the lower side of the base member. In the centre of the member 3 is a raised boss 7 forming the burner proper. Fuel supplied by a pipe 11 burns in the concentric wells 8, 9 and 10, any overflowing fuel being carried away by the pipe 15. The base member 1 has a central orifice 16 into which fit two semicircular members 17 which together form a disc with an aperture 19 and a depending wall 21 terminating in a flange 22 in spaced relation to the surface of the pan 3. The wall 21 causes the combustion air entering at 6 to take a tortuous path and also acts as a baffle to prevent back draughts. Above the burner is mounted a flame spreader 25 which directs the flame on to the base member at about the point indicated by 30 thus warming the incoming air and supplying heat to the floor below the stove. The supply of fuel is regulated by a thermostatic element.
