Title: Apparatus for forming hollow cylindrical structures
IPC: B29C53/70
Filed: 1972-03-07
Abstract: 1356863 Forming hollow bodies by winding A PIOLA 7 March 1972 [10 March 1971] 10645/72 Heading B8G [Also in Division B2] A winding apparatus for making a hollow cylindrical body comprises a vertical cylindrical mould 1, a carriage 2 having ground-engaging wheels 3 and further wheels 5 that engage the mould 1. A drive member 17 on the carriage 2 meshes with a reaction element 7 encircling the mould 1 and causes the carriage to move around the mould. The carriage carries a column 21 on which is a vertically sliding member 23. A motor 16 causes (a) the member 23 to reciprocate on the column 21; and (b) the member 17 to rotate about the mould 1. The carriage carries one or more holders 41 for reels 42 of reinforcing material, there being guide means 51 on the slide member 23 to apply the reinforcing material 55 on to the surface of the mould 1. The carriage also carries means 44, 45 for impregnating the material 55 with a liquid resin containing polymerizing catalysts. The reaction element 7 may be a chain, a belt or a stationary rack. The rate at which the slide member 23 reciprocates vertically may be varied with respect to the speed at which the carriage 2 travels around the mould 1. In Fig. 1 (not shown) the slide member 23 carries a reel (37) of reinforcing material in web form, the slide member 23 moving up and down the column 21 to traverse the web (54) on to the mould 1. Spray guns (35, 36) carried by the slide member 23 spray the web (54) with a catalystcontaining liquid resin and presser rollers 40  press the web against the mould 1. The web may be of glass fibres, rock wool, asbestos, rayon, nylon or the like and is applied to the mould before the reinforcing material 55 is applied. Prior to distributing the web from the reel (37) on to the mould 1 the mould 1 may be sprayed with an anti-adhesive material, such as silicone, wax or the like, or alternatively a layer of an anti-adhesive material, such as siliconized paper or the like is wrapped around the mould in similar manner to the web (54).

Title: Method and apparatus for the recovery of pulp fibres from waste paper
IPC: D21C5/02
Filed: 1974-03-12
Abstract: 1463119 Pulping waste paper BELOIT CORP 12 March 1974 [22 March 1973] 10958/74 Heading D2A To recover substantially dry pulp from waste paper an amount of aqueous moisture and a liquid immiscible with water are added to the waste paper, the mixture is defibred at elevated temperature and pressure, then the aqueous moisture is removed from the fibres to a predetermined dryness by reducing the pressure to atmospheric and the immiscible liquid is removed substantially completely from the fibres. The immiscible liquid, preferably tetra- or tri-chlorethylene, protects the fibres and prevents dumping while the moisture breaks the bonds between fibres. As shown waste paper is supplied to a chamber 12 where it is subjected to a countercurrent of superheated steam 14 and a spray 15 before being passed through a rotary valve 16 into a pressurised mechanical defibrer 19 where preheated immiscible liquid is added on line 46 to bring the mixture to about 96% liquid, 2% water and 2% pulp. The mixture then passes to a separator 21 having a rotating tubular screen 22 divided internally by a stationary wall 27. Fibres pass around the outside of screen 22 to an outlet 31 while the immiscible liquid, carrying any contaminants, flows out through outlet 23 to be recycled and replaced by preheated fresh immiscible liquid on inlet 26. The mixture on line 31 is fed to a second pressurised defibrer 32 and thence to a demoisturing tank 35 at atmospheric pressure. Most of the water and some of the immiscible liquid evaporate off in the tank 35 to be recycled by system 35b. The remaining mixture is fed to a mechanical press 38 where the immiscible liquid is removed to be subsequently filtered at 44, heated at 45 and fed back to defibrer 19. Fibres from the press 38 are passed to a chamber 39 where they are subjected to a countercurrent of superheated steam to evaporate the remaining immiscible liquid substantially completely, and to control the dryness of the fibres.

Filed: 1970-03-07
Abstract: 1281984 Measuring peak voltages MARCONI INSTRUMENTS Ltd 14 Jan 1971 [7 March 1970] 11031/70 Heading G1U A peak detecting circuit comprises a first storage capacitor C1 having a short discharge time constant, and a second storage capacitor C2 having a discharge time constant which is normally long relative to that of the first capacitor but which is reduced when the voltage stored by the first capacitor drops below a selected level. The input signal (I.P.) charges capacitor C1 via a transistor T1, which in turn charges capacitor C2 via a diode D. So long as C1 is sufficiently charged, a further transistor T2 is cut off and capacitor C2 has a very high resistance discharge path. If the input signal is removed, capacitor  C1 starts to discharge through a resistor R, and as soon as its voltage falls below that on C2 a feedback path via output amplifier C3 cuts off the charging path for C1. Further, when, as it continues to decay, the voltage on C1 falls below a reference level V REF  transistor T2 conducts to discharge capacitor C2.

An explosion-proof sealing box is attached to the side of the terminal box of an electric motor so that the high rate of rise of pressure generated under faulting conditions is counteracted by rapid pressure relief by the easy expansion of insulating material through a frangible partition in the sealing box close to the fault location. The sealing box 3, secured to the terminal box 1, is divided by the frangible partition 4 into main 5, and subsidiary compartments 6, the main compartment 5, containing an insulating material 16, either oil or a thermosetting resin, completely surrounding the crutch of cable 7, and the subsidiary compartment 6, containing either air or a foamtype plastic material. If the pressure rises above a predetermined value the insulating material expands, fractures the partition 4, and insulating material flows into the subsidiary compartment. This provides a temporary pressure relief measure and further relief is provided in a side wall of the terminal box 1, by means of aperture 24, covered by frangible diaphragm 25.

Filed: 1920-04-21
Abstract: 166,711. Rustproofing Syndicate, Ltd., and Newman, T. F. April 21, 1920. Coating.-Ferrous metals are rendered rust. proof by coating first with copper and then with an alloy of tin-mercury or tin-zinc mercury. The articles are freed from grease and oxidized scale, and after traces of acid are removed are immersed for a second in a solution of copper sulphate with sulphuric acid. After neutralizing adhering acid in a lime or other bath the articles are placed in a boiling solution of caustic soda containing a quantity of granulated tin and a smaller amount of mercury. If the articles are immersed in contact with a perforated zinc-lined basket, the zinc acts as the positive electrode and a deposit of copper-tin-zinc-mercury is formed electrolytically. The preliminary copper coating may be deposited bv electrical or other means. The articles may subsequently be heavily coated with any metal.

Abstract: 288,988. International General Electric Co., Inc., (Assignees of A. E. G.-Union Elektricitõts Ges.). April 16, 1927, [Convention date]. Exciting.-A continuous-current dynamo-electric machine, particularly for use in electric arc welding, has shunt and series excitation, the coils of the shunt winding being arranged in the normal manner so that alternate poles have opposite polarity whereas the series winding assists the shunt winding on some of the poles and opposes it on the other poles, and the effects of the compounding and counter-compounding coils are caused to differ. As shown, the series coils 7, 8 assist the shunt coils 3, 4 and the series coils 5, 6 oppose the shunt coils 1, 2. The object of the invention is to limit the shortcircuited current and to obtain a substantially constant current over a given voltage range. In order that a short-circuit current may be generated, the series coils 7, 8 have a greater number of turns than the other series coils, Alternatively, the brushes may be rocked, the air gap under the poles III, IV may be made smaller than the air gap under the poles I, II, or the counter-compound winding may be shunted. Specification 25744/07 is referred to.
