Abstract: In the fixation of nitrogen, say as oxides of nitrogen by reaction with oxygen or as hydrocyanic acid by reaction with a hydrocarbon, by means of an electric arc whilst employing electrodes of heavy metals, at least one of the electrodes contains an alkali or alkaline earth metal alloyed with the metal of the electrode.  The heavy metals referred to are copper, silver, nickel and iron and alloys such as chromium-nickel steel, nickel-copper alloys and the like.  These may be alloyed with alkali and/or alkaline earth metals such as sodium, lithium, calcium, strontium and barium.  The production of nitrogen oxides from air and the production of hydrocyanic acid by the reaction of nitrogen with methane or petrol vapour is referred to. Specification 23959/13, [Class 1 (ii), Inorganic compounds, other than &c.], is referred to.

Abstract: 404,439. Land, garden, and road rollers. BARFORD & PERKINS, Ltd., and KNIGHT, F. B., Invicta Works, Rochester, Kent. Nov. 22, 1932, No. 32998. [Class 6 (i).] A motor-driven hand-steered roller comprises two separate driving rollers driven by differential gearing and a third roller which rolls the ground between the other two and supports the motor. The chassis comprises two side plates carrying the main rollers 5 and rigidly secured on a box-like framework 2 which carries the motor 3 and the front roller 4, the weight being distributed so that the roller pressures on the ground are equal. Power is transmitted to the rollers 5 through universal joints, a gear box, and two clutches mounted between the rollers. A shaft driven by a chain 10 from the gear box drives a differential which drives one roller 5 directly and the other through a shaft 20 and a sleeve thereon. The hand steering- lever 26 is screwed into a member bolted to the side plates. A brake is actuated by a handlever 27, the throttle by a lever 35, and the clutches by a lever 30, rod 31, crank arm 32, and a double spring connection 37. The clutches may be such as described in Specification 343,900, [Group XXXI], forward speeds being engaged when the lever 30 is in the forward position and reverse speeds when it is in the rear position. In a modification there is no reverse gear and the clutch lever operates in the plane of the steering handle. A bracket on the steering handle carries a wheel to come into contact with the ground when the front roller 4 is raised for turning a sharp corner.

Abstract: 647,545. Recording apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 16, 1947, No. 33195. [Class 106 (iv)] [Also in Groups XX and XL (c)] A reversible drum-to-drum tape, film, or like winding mechanism is characterized in that the winding drums are mechanically coupled to the planet wheels of a gear mechanism of the epicyclic type, the planet wheels being biassed with respect to the sun wheel so as to maintain the tape in tension, and the gear ratios being so chosen that the epicyclic movement of the planet wheels compensates for the effects of increase and decrease in effective drum diameters due to winding of the tape. As shown, the arrangement is suitable for indicating the tuning of a radio receiver and is provided with a tape T marked with a scale and passing over a jockey pulley J, the ends of the tape being respectively fixed to similar spools S1, S2. Each spool is attached to the shaft of one of two similar gear-wheels PG1, PG2, arranged as the planet wheels of an inner wheel SG and running in bearings in the ends of links R1, R2, pivotally mounted on the shaft of the inner wheel, and spring-biassed in the direction of the arrows A1, A2 to keep tension on the tape. The drive may be applied to one of the planet wheels, the inner wheel, or the intermediate wheel J, and an expression is given for calculating the gear ratio to give the required compensation. Friction wheels may be used instead of toothed gear-wheels. In an alternative arrangement for a two-waveband radio receiver, Fig. 3 (not shown), two indicator tapes running at different speeds are provided each having an epicyclic gear mechanism arranged around a common inner wheel.

Title: Improvements in or relating to the manufacture of pressed or moulded articles
IPC: C08L97/02
Filed: 1928-11-16
Abstract: 325,281. Bayon, H. P., (Magnasco Roggero & Co.). Nov. 16, 1928. Moulding resin-impregnated sheets etc.; processes.-Plastic sheet material for the production of pressed or moulded articles is made by treating sheets of cellulosic material, for example woodpulp sheets, with an aqueous solution of an oxidizing acid or acid mixture, for example 10 per cent nitric acid or 10 per cent nitric and 10 per cent sulphuric acids, and then impregnating the material with a solution comprising a synthetic resin. The material is then subjected to heat and pressure to render the resin insoluble. The acid used must not be of sufficient strength to parchmentize or combine with the cellulose. Preferably the material, after the acid treatment, is impregnated with liquids comprising substances capable of combining to form a resin, for example, phenol and formaldehyde, and is then heated to form an initial condensation product in the material. Two or more sheets of the material may be compressed together at a temperature insufficient to convert the condensation product to the infusible state. Sheets of woven fabric may be interposed to reinforce the material. Shaped or moulded articles may be made by compressing the laminated sheets in moulds, and heating with or without pressure to convert the resin. In an example, sheets of wood pulp about .5 mm. in thickness are steeped in an aqueous solution containing 10 per cent by weight of sulphuric acid and 10 per cent of nitric acid for 12 to 24 hours. The acid is drained off, and the sheets are pressed or centrifuged, neutralized and washed with water. After drying, the sheets are steeped in melted phenol and then soaked in a 40 per cent formaldehyde solution to which 5 per cent of sodium carbonate is added. After draining and drying, the sheets are treated with an alcoholic solution containing 5 per cent by weight of paradi-chlorbenzene. After drying and storing, the sheets are cut to size, placed in moulds, heated to 60‹ C. and pressed for a few minutes. They are then placed in a finishing container under high pressure and heated at 160‹ C. for an hour in a bath of paraffin wax. While still hot, the article is submitted to hydraulic pressure of 2500 lbs. per square inch.

Abstract: 1,154,724. Organopolysiloxanes. MIDLAND SILICONES Ltd. 2 Aug., 1966 [11 Aug., 1965], No. 34375/65. Heading C3T. An organopolysiloxane is made by reacting a hydroxylated organopolysiloxane .with a Si compound containing at least one Si-bonded alkoxy radical, the reaction being effected in the presence of a catalyst which is a substantially neutral finely-divided solid which is insoluble in the reaction medium and has a sufficiently high surface energy to absorb the reagents, but exerts no significant molecular sieve action and which is selected from metal oxides, silica, powdered metals, metal phosphates, metal sulphates, metal chlorides, metal silicates and natural and synthetic clays. The preferred starting materials are (1) siloxanes having the general formula HO(RaSiO4-a/2) b H, wherein a is 1À99 to 2À0, b is an integer greater than 1, and each R is a monovalent hydrocarbon (h.c.) radical with or without halogen substituents; and (2) silanes of the formula R<SP>11</SP> n Si(OR<SP>1</SP>) 4-n  wherein n is 0, 1, 2 or 3, R<SP>11</SP> is a monovalent h.c. radical and R<SP>1</SP> is an alkyl radical of 1 to 3 C atoms. Catalysts specified are Al 2 O 3 , SiO 2 , fuller's earth, calcium silicate, vermiculite, kaolin, Fe, BaSO 4  and NaCl, and are usually used in amount of 0À03 to 1% by wt. of the reactants. The reaction is preferably effected at 120 to 160 C. and may be carried out in inert solvents, e.g. benzene, toluene and xylene and under a blanket of a dry inert gas. If desired the catalyst may be removed, e.g. by filtration. In a typical Example (1), an OH- terminated dimethylpolysiloxane was reacted with CH 3 .Si(OCH 3 ) 3  in the presence of fuller's earth at 150 C under a blanket of nitrogen, with subsequent stripping of volatiles and filtration to yield the desired methoxylated polysiloxane, which on mixing with tetrabutyl titanate and exposing to the atmosphere, cured to an elastomer. Uses: as intermediates in making hightemperature resinous and elastomeric compositions and R.T.V. rubbers. Diorganosiloxanes having 2 or 3 alkoxy radicals attached to each terminal Si atom cure to rubbers in the presence of moisture and can be used for coating paper, metals or other substrates, or they can be mixed with fillers, e.g. TiO 2 , ZnO 2  or CaCO 3  and used for potting, sealing, moulding and encapsulating materials.
