Title: Improvements in cylindrical moulds or drums for wood-pulp and cellulose
IPC: D21F9/04
Filed: 1920-07-27
Abstract: 170,918. Aktiebolaget Karlstads Mekaniska Verkstad, and Wagner, R. E. July 27, 1920, Cylinder paper machines; cylinders and drums; pulp, catching and recovering.- Cylindrical moulds or drums for wood pulp aud cellulose, such as are used for wet machines, pulp vats, thickeners for pulp, water extractors and collectors, comprise a rotary perforated cylinder divided into cells or compartments 3 by partitions 23 mounted between members 21, 22. Within the cylinder is a stationary suction box composed of two disc-like members 26, 27 joined by a peripheral cylindrical wall 28. The shaft 11 passes in a tube 29 through the box. The upper part of the mould rotates in a pulp container 1. A small chamber 8 in the suction box presents a wall 10 against the compartments when they first enter the container. The first layer of pulp thus settles on the mould by gravity and water drains into the compartments. The water drains out of the compartments through an opening 9 into the chamber 8. Thus the mould is provided with a straining-layer of pulp before suction is applied, which suction continues until immediately before the pulp layer is removed from the mould.

Abstract: 714,078. Electrolytic surface treatment of aluminium. EVER READY CO. (GREAT BRITAIN), Ltd. Aug. 27, 1952, [Sept. 24, 1951.] No. 2334.4/51. Class 4I. Articles of aluminium or an aluminium-rich alloy are polished by immersion in a heated electrolyte comprising phosphoric acid, sulphuric acid, a phosphoric acid ester of a polyhydric alcohol or a salt thereof, and water; after a period, during which etching is effected, the article is connected as anode to direct current voltage. Suitable proportions for the electrolyte are 45-80 per cent by weight of phosphoric acid, preferably orthophosphoric, 5-20 per cent of sulphuric acid, and 1-5 per cent of the phosphoric acid ester or salt. The latter constituent may be glycerophosphoric acid or its sodium or potassium salt. The period before passage of current may be 3o-6o seconds, the bath temperature 70‹-90‹C. and the anode current density 100-180 amps per sq. ft. The anode support may be reciprocated to agitate the electrolyte. The cathodes may be of lead or graphite and are preferably of area substantially greater than the projected area of the article under treatment. The article after electrolytic treatment may be washed in water containing a wetting agent, and a thin surface film present thereon removed by immersion in a solution of chromic and phosphoric, or chromic and sulphuric, acids or of salts of these acids. The articles may then be anodized in a chromic acid or sulphuric acid bath to produce an opaque or transparent coating and the coating dyed and/or sealed. An impact-extruded or deep-drawn article e.g. an electric torch case may be subjected to a light mechanical polishing before the electrolyte polishing.

Title: Malonic acid esters and their polymers
IPC: C08F18/08
Filed: 1944-11-14
Abstract: Diallyl acyl malonates of the general formula <FORM:0592421/IV/1> wherein R and R1 are aliphatic carboxy acyl radicals, or R may be hydrogen, and X is hydrogen, halogen or an alkyl group are prepared, by reacting a dialkyl sodio-malonate with a carboxy-acyl halide whereby the sodium is replaced by acyl groups, treating the resulting dialkyl acyl malonate with an allyl alcohol of the general formula CH2=CX.CH2OH in the presence of an ester-exchange catalyst and recovering the diallyl acyl malonate so obtained by distillation, or are prepared by reacting a diallyl malonate with sodium whereby one or both hydrogen atoms attached to the alphacarbon atom are replaced by sodium and then reacting with an acyl halide so replacing sodium by the acyl group.  The acylation step is preferably carried out at 20 DEG  to 35 DEG  C.; the ester-exchange may be effected with any mineral or sulphonic acid and, preferably, in the presence of excess of the allyl alcohol. The acyl malonates are stated to be novel and may be polymerised alone or co-polymerized with other monomeric substances especially mono - vinyl and vinylidene compounds such as styrene, acrylonitrile, methacrylonitrile, methyl-, ethyl and butyl-methacrylates, butyl acrylate, vinyl chloride or vinylidene chloride.  Polymerisation is effected at temperatures up to 100 DEG C. in the presence of polymerization catalysts such as ultra-violet light, organic peroxides, sodium borate or sodium peroxide; an inert organic solvent, for example, dioxane, benzene or toluene may be present.  Copolymerisation with a vinyl-chloride-vinylidene chloride mixture may be carried out in aqueous emulsion.  In an example, an ethereal solution of diethyl malonate is treated with sodium and then with acetyl chloride and distilled to yield fractions of diethyl mono- and di-acetyl molonates which are separately heated with excess allyl alcohol in the presence of p-toluene sulphonic acid to form the corresponding diallyl acetyl-malonates.  Reference is made to similar compounds in which the acyl groups are derived from propionic, butyric, valeric and chlor-acetic acids and the ester-forming radicals from methallyl, ethyallyl, propyl allyl, butyl allyl, chlorallyl and bromallyl alcohols.  The Specification as open to inspection under Sect. 91 includes the preparation of esters of the above general formula wherein R and R1 may be acyl radicals or R may be an alkyl group for example, benzoyl, salicylyl, phenyl acetyl, methyl, ethyl, propyl and butyl.  This subject-matter does not appear in the Specification as accepted.

' In glass furnace charging arrangements in which the batch materials are deposited on the surface of the molten glass in the form of a sheet or layer and propelled into the furnace by mechanical means, e.g., as described in Specification 627,642, the direction of movement of the sheet or layer is controlled by applying a retarding force at one or more points thereof. In one form, Figs. 2 and 3, a water-cooled element 7 is arranged in front of a rotary feeder 3 which acts on the sheet -of batch material 5 deposited by a hopper 11 on the surface of the molten glass in an extension 4 of the tank. This element is mounted . in adjustable supports 14, 15 so that its' height and inclination may be varied, and is arranged to produce a differential retarding action across the width of the sheet so that the latter is caused to swing to the right. In a modification, Fig. 5, the element.,is curved so as to effect a maximum retarding action at the edges of the sheet and a minimum or zero retarding action at the centre, the sheet being thus caused to spread out fanwise. A similar element may be used' when two sheets of batch are fed side by side by two rotary feeders, see Fig. 6 (not shown). In a second form, Fig. 7, a series of water-cooled elements 10, the. heights of which are individually adjustable, are arranged between the rotary feeder 3 and the point where the batch is deposited by the hopper 11. Fig. 9 (not shown) illustrates the application of the invention to a charging mechanism comprising a reciprocating feeder 13.
