Title: A device for recovering the liquid from a liquid-containing material
IPC: B30B9/20
Filed: 1962-10-25
Abstract: 958,014. Filters. MACHINENFABRIK FRANS SMULDERS N.V. Oct. 25, 1962 [Oct. 27, 1961], No. 40389/62. Heading B1D. A rotatable disc or roller 1, Figs. 1 and 2, having a flange 1a and having a rough surface forms a pressing chamber 3 with a curved guide surface 2, composed of straight bars 4, the longitudinal axes of which extend perpendicular to the direction of movement of the disc or roller. The bars, with gaps between to allow passage of liquid, rest on curved support bars 5 which in turn rest on frame 6. The pressing chamber converges towards the outlet for material pressed therein. Passages 7 are provided in frame 6 for discharge of liquid. Spacing pieces 8 maintain the gaps between the bars 4. The shape of the pressing chamber 3 which may be locally non-converging or even diverging provided overall convergence is maintained, may be altered by exchanging the curved support bars 5, or by adjusting them radially with respect to the disc or roller by means of one or more members, adjustable relative to the frame, or each support bar may be composed of a plurality of ring segments, the positions of which are variable with respect to the disc or roller. In one embodiment, Fig. 3, the bars are arranged with their longitudinal axes radial with respect to the roller, so that they are surrounded by the pressing chamber on three sides. The upper faces of the bars 4 may be bevelled, so that the guide surface is stepped, or the bars may be provided with grooves or corrugations transversely of their longitudinal direction.

Title: Improvements relating to driving arrangements for steered motor wheels
Inventor: KRAUS LUDWIG
IPC: B60K17/30
Filed: 1964-10-05
Abstract: 1,037,007. Driving steerable wheels. DAIMLER-BENZ A.G. Oct. 5, 1964, No. 40492/64. Heading B7H. The steerable wheels of a vehicle are driven through preferably homokinetic universal joints G and cardan shafts g, g<SP>1</SP> from a differential gear-box D which is arranged below the axis passing through the wheel centres to reduce the resistance to steering wheel movement when cornering due to the angularity between the stub axles x, x<SP>1</SP> and cardan shafts. Due to the differential, particularly if it is of the limited slip type, the driving load and hence effect on the steering is greatest for the inside wheel on a curve and by reducing the angle between the shaft g<SP>1</SP> and stub axle x<SP>1</SP>, the reduction in the effect on the steering due to the inside wheel is greater than the increase in effect due to the outside wheel, the stub axle x of which is at a greater angle to shaft g than with a normally placed differential gear-box D 0  (shown in broken lines) on the axis through the wheel centres giving a net reduction in steering effort.

Title: Improvements in and relating to charging circuit arrangements for pulse forming networks
Inventor: SCOLES GRAHAM JOHN
IPC: H03K3/55
Filed: 1959-11-30
Abstract: 964,509. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 30, 1960 [Nov. 30, 1959], No. 40635/59. Heading H3P. A charging circuit for a pulse-forming network PFN includes an electronic device controlled by a signal derived from the PFN for diverting excess charging energy from the PFN. In Fig. 8, the PFN is resonantly charged from the secondary of transformer T via an inductor L and diode D and discharged via a load R when the switching tube S is triggered. The thyratron TH is made conductive by the output of amplifier A when the peak voltage at the anode of the hold-off diode D exceeds a value set by the potentiometer PD. When conductive, the thyratron TH limits the voltage to which the pulse-forming network PFN can charge by shunting the circuit R1, R2, C across the inductor L and the supply transformer T. Relay RY is energized when the thyratron TH conducts, changing over the supply to the split phase motor RM (Fig. 9) which reduces the setting of the adjustable autotransformer VR feeding the transformer T of Fig. 8. In circuits operated from D.C. supplies, a grid-controlled rectifier can be similarly controlled. In Fig. 7, tube V is coupled inductively to the charging inductor L so as to divert charging energy when the potential across potentiometer PD exceeds a predetermined level.

On starting up, valve 3 is open and valve 10 closed and the tapped-off stream is removed to the heat exchanger 5 from the main stream by a centrifugal pump 4. When steady conditions prevail, pump 4 is stopped and, with valve 10 open and valve 3 closed, the tapped-off gas is supplied to the heat exchanger 5 from the outlet of the jet pump 2, via the line 11. Pumping thereafter will be determined by the heat supply to the heat exchanger 5.

Title: Yarn texturing
IPC: D02G1/08
Filed: 1973-09-06
Abstract: 1398371 Texturing yarns; regulating tension; false-twisters R C SPURGEON 6 Sept 1973 41950/73 Headings DID D1F and D1W In a process for false-twist texturing continuous multifilament synthetic e.g. nylon or polyester, yarns wherein such yarn is pulled by the final take-up means through successive heating, twisting and untwisting zones, the yarn is controlled (as by twist stop(s) and yarn check(s)) at spaced locations along its path so that no twist applied in the twisting zone runs back into the heating zone and no relaxation i.e. slackening and/or change in length, occurring in the untwisting zone is reflected in the twisting zone. Thus the twisting is applied uniformly with consequent uniformity in the textured yarn which is described as devoid of "spiky" or "bristle-like" projections. The twisting zone may provide both primary and secondary twisting. As shown, yarn Y passes successively through a tensionlevelling device 10, an electric heater 12, twiststop device 14, false-twisting apparatus 16 and a check device 18. In the device 10 a change in the tension of the yarn downstream thereof causes or allows rings 24 and 30 to move up or down standards 22 and 28 thereby changing the degree of yarn wrap around the surface of a roller 20 (rotating at a constant speed which exceeds the linear speed of the yarn end and is in the yarn advancing direction) and thus the slippage therebetween with a resultant regulation of yarn tension. Apparatus 16 comprises an individually driven rubberedged disc 66 frictionally engaging the yarn normally to the direction of trawl thereof or, as shown, at an angle e.g. 60‹, thereto: it is combined with device 18 comprising another individually driven friction disc 70, the extent of yarn wrap around the edges of the discs being determined according to the position of guide 84 relative to guides 82 and 86. In a modification, Fig. 3 (not shown) the primary (false-) twisting is effected by a hollow spindle, through which the yarn passes and makes one turn around a cross-pintherein, cooperating with a disc 70.

Abstract: In the distillation of water or other scaleforming liquids in an evaporator 20 provided with tubes 32 surrounded by a chest 30, wherein the feed water is boiled in the tubes, the vapour is passed to compressor 40 and most of the compressed vapour is then used as a heating-medium in chest 30, the formation of heavy scale inside the tubes is prevented by passing a portion of the compressed vapour through line 82 into a vessel 80 which contains an acid, and forcing the acid through line 86 into the water which is being fed into the evaporator through conduit 22. Alternatively, the acid may be dissolved in some of the feed water and the concentrated solution is then allowed to diffuse slowly into the feed stream.  Hydrochloric, sulphuric, acetic and citric acids and sodium bisulphate are specified as scale-treating materials, and reference is made to inhibitors for preventing the attack on metal by acid.  The distillate is withdrawn from chest 30 via line 46, together with a mixture of gas and vapour.  The vapour is condensed in vent-condenser 16, and the condensate p  joins the main distillate flowing down line 52.  The feed water enters the system through conduit 10, and first passes through preheater 12 where it passes in heat-exchange relation with the distillate and the blowdown, withdrawn from the evaporator by pump 58.  The preheated feed flows through vent condenser 16 into <PICT:0935178/III/1> conduit 22, where it is treated with acid, and then enters the evaporator.  The appropriate time to open the vent-valve on condenser 16 is indicated by pressure-gauges 110 and 112. Auxiliary heat can be supplied to the evaporator by means of the cooling liquid from the jacket of the diesel engine which drives compressor 40; the exhaust gases from the engine may also be used.
