[Class 2 (iii)] Resinous compositions are prepared by condensing a phenol, lignin and an excess of aqueous formaldehyde in the presence of 0.5-5 per cent. of the weight of phenol of a basic alkali-metal compound as catalyst at a temperature not exceeding about 100‹C. for about 30 minutes and insufficient to cause separation into layers, adding to the resulting liquid from 0.25 to 20 per cent. of the weight of phenol of ammonia, an amine or mixtures thereof, reacting the resultant mixture at a temperature of 110‹C. for a period 5-20 minutes, insufficient to cause separation into layers, and dehydrating. Hydroxides, carbonates, borates and cyanides of the alkali meta s are specified as catalysts. sodium hydroxide being preferred. The amount of lignin is 10-130, preferably 85-110 parts per 100 parts phenol. The nuclear ratio of formaldehyde to phenol is preferably from 1.25 to 2.5. Examples are given of the working up of phenol and lignin and sodium hydroxide with aniline, ethylene diamine and ammonia ; and of the compounding of the resin i.e. with wood flour, asbestine, clay and cloth cuttings, colouring materials, mould lubricants and plasticizers, preferably with a small amount of hydrated lime to expedite conversion to the infusible state under heat and pressure. Thus, the resin is first compounded with hydrated lime, calcium stearate and montan wax, then blended with wood flour and sheeted on hot rolls for 30 seconds to give a moulding composition.

Abstract: 899,295. Gas turbine plant. DOWTY FUEL SYSTEMS Ltd. May 13, 1959, No. 16469/59. Class 110 (3). [Also in Group XXIX] A main fuel pump 1 discharges into a pipe 8 leading to an engine driven circulating pump 2 which is part of a circuit comprising a supply pipe 4, spill nozzles 3, and spill pipe 6 that opens into the pipe 8 upstream of the pump; the pipe 8 may be connected to the supply pipe 4 instead of the spill pipe 6. The output of the pump 1 is controlled by a by-pass valve 11 actuated by a piston 18, the position of which is determined by a leak-off closure 45 on a hinged beam 27. The beam 27, which is urged counter-clockwise by a spring 29, is adjustable from a manual speed control lever 33, and is acted upon by a pair of opposed bellows 34, 35, the former being evacuated and the latter subjected to the output pressure of the compressor of the gas-turbine engine with which the fuel system is associated; the bellows are of equal area. Connected to the beam on the opposite side of its pivot 28 are a pair of opposed pressure pads 38, 39, each formed of a piston acting against a rubber diaphragm; each pad may alternatively comprise a bellows or diaphragm. Pad 38 which is larger than pad 39, is connected to the outlet of the circulating pump 2 whilst pad 39 is also connected to the latter but at a point radially between its inlet 7 and outlet 5; the influence of the pads on the beam 27 is speed responsive, the governing characteristic being stable since pressure in pipe 8 is added to that of the pump 2. When the engine is used at ground level only the bellows 34, 35 may be omitted.

Filed: 1918-10-12
Abstract: 133,462. Ray, C. W. Oct. 12, 1918. Combustion-product plant. - A pump actuated by an internal-combustion engine compresses air, a portion of which is supplied to the internal-combustion engine and the remainder mixed with hot burnt gases from the internal-combustion engine and expanded in a separate engine or an independent cylinder. In the form shown in Fig. 3, an internal-combustion engine a actuates a pump b which charges with air a reservoir x from which the engine is supplied through a valve y. The remainder of the air is discharged through a valve j and a jacket space around the engine a and mixes with burnt gases escaping through piston-controlled ports. The mixture of air and burnt gases is expanded in cylinders d. According to a modified method of working, the remainder of the air in the reservoir x may be discharged through the engine a to scavenge the cylinder. A modified construction is described in which the mixture of air and burnt gases is expanded in an independent motor. According to a further modification, the air pump is driven from the internal-combustion engine through a belt or chain. Instead of supplying air from the pump to the combustion cylinder, the latter cylinder may draw in its own charge, which, after combustion, mixes with the air from the pump.

Abstract: 474,522. Valve generating circuits. SIEMENS & HALSKE AKT.-GES. June 16, 1937, No. 16772. Convention date, June 16, 1936. [Class 40 (v)] The frequency of a valve oscillator is rendered independent of temperature changes by means of a temperature-dependent impedance in the valve anode circuit which reflects a variable capacity effect into the circuit of the grid or grids and so balances variations caused by changes in the temperature of the reactance elements of the oscillatory circuit. The anode impedance may be a resistance with a negative temperaturecoefficient such as uranium dioxide, copper oxide, carbon, or dilute acids, or with a positive temperature - coefficient such as an ironhydrogen resistance. The temperature-impedance characteristic may be regulatable, e.g. by using a combination of several impedances with different characteristics and tapping variable portions of them into circuit. The Figure shows a suitable circuit employing a two-grid valve 1 with coupled tuned circuits 6, 7 and 8, 9 associated with its outer and inner grids 4, 3 and with its anode 2 connected to a load 12 through the temperature-dependent impedances 14, 15. Regulation is effected by adjusting the impedance 15.

Filed: 1973-04-09
Abstract: 1423728 Making pipes SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 9 April 1973 16891/73 Heading F2P A fibre-reinforced resin pipe is made by forming a number of tubular layers individually on a mandrel, one of the layers being a reservoir layer of material impregnated with a flowable and hardenable thermosetting resin and another layer being a constriction layer, which is applied under tension after formation of the reservoir layer, so that the resin is expelled from the latter into a reinforcement layer. In one way of performing the invention, a tape 16 of fibrous material, e.g. of square weave glass fibre, and a strip 17 of reservoir material, e.g. of flexible open-cell polyurethane or natural or synthetic elastomer foam, are wound on to a rotating mandrel 10 from a traverse 12, while strip 17 is being impregnated with a thermosetting resin, e.g. flowable epoxy, formaldehyde or polyester resin, from a spray nozzle or slit, arranged between reel 14 and mandrel 10. On the return run of traverse 12, a further tape (18) of fibrous material is wound, under tension caused by means of an adjustable friction clutch acting on reel 15. Many variations are described, thus, the constricting layer (18) which causes exudation of the resin, instead of remaining as part of the finished pipe, may be an endless band, which is continuously wound on the reservoir layer at one location and wound off at another. In order that the winding may be entirely performed with materials in an externally dry condition, the resin may be introduced between two strips of reservoir material, wound together in face-toface contact.
