Title: Manufacture of artificial staple fibre
IPC: D01G1/08
Filed: 1937-08-19
Abstract: 500,886. Stapling and mixing fibres. GROVES, W. W. (I. G. Farbenindustrie Akt.- Ges.) Aug. 19, 1937, No. 22745. [Class 120 (iii)] [Also in Group IV] An artificial staple fibre mixture is made by spinning continuous threads of different titre, collecting the threads in one or more bands or bundles, cutting or tearing the band or bands into staple fibres of different lengths and loosening and mixing the fibres with the aid of a moving liquid. The threads of different titre are produced by using, in the spinning machine, nozzles with different numbers of perforations, by feeding the different'nozzles with the spinning solutions by pumps having different outputs, by feeding the different nozzles with the solutions under different pressures, by feeding the different spinning pumps with solutions of the thread-forming substance of different concentrations, or by conducting the different bundles to the cutting machine under different drafts, or by combining two or more of these methods. The bundles of continuous threads may be torn in the apparatus described in Specification 416,636 or the several bands may be separated and cut in different machines or by knives arranged on a roller at different distances from each other or by knife rollers driven at different speeds. Specification 244,715, [Class 120 (i)], also is referred to.

Class 59 In a rotatable drum of a ball or tube mill provided with a lining comprising several cylindrical sections located adjacent each other, the sections consisting of wear resistant material, e.g. rubber, rubber coated metal, steel, each section consists of a flexible, preferably resilient, band which after having its ends joined together forms a closed ring which is given such dimensions relative to the inner, diameter of the drum, that the ring is subjected to a peripheral compressive stress maintaining it in place in the drum solely by its radial pressure against the drum. As shown in Fig. 2, the ends 11 of each band 6 are vulcanized or welded together after such ends have been stressed by being urged in opposite peripheral directions. The band is longer than the inner circumference of the drum and after having its ends joined together outside the drum is introduced into the drum at one end thereof. In a modification, Fig. 3, the edges between adjacent bands are coverd by an annular band 12 of the same material; alternatively, the edges between adjacent bands may be fused together. In another modification, Fig. 4, the band comprises two ore more sections 14, 14<SP>1</SP> . which are joined together by means of a grooved bar or bars 15 extending over the entire axial width of the band. In a further modification, Fig. 5, the lining is formed of a--single band 19 which is wound helically, inside or outside the drum. and each end of the band is joined at 20 to the adjacent turn of the band.

Abstract: 295,256. Soc. Anon. Union Technique du Batiment et des Travaux Publics, (Assignees of Langevin, P., and Hocart, R.). Aug. 6, 1927, [Convention date]. Electric - diaphragm pressure gauges; piezoe l e c t r i c pressure gauges.-To measure varying pressure in liquid conduits a piezoelectric crystal subjected to the pressure is employed and connected to a four-electrode valve and measurement is made by an oscillograph. A flanged conduit e has attached to it a casing b with an elastic steel diaphragm d with reduced annular portions d<1>. The crystal a bears against the diaphragm and rests in a groove in a base plate c against which bears screws m<1>, m<2> for adjusting the pressure. The faces of the crystal are connected, the negative to the outer grid f, and the positive to the filament h of a four-electrode valve and the inner 'grid i is made positive and connected to an oscillograph j of which the period (<1>/1500 second) is below the periods concerned. The dimensions of the quartz crystal a and diaphragm d are also chosen greatly to exceed in natural frequency that of the variations in the pressure to be measured. The sensitiveness of the apparatus may be varied by the interposition between the valve and the oscillograph of amplifying means with suitable resistance and batteries, and by shunting the crystal by a variable condenser. A mirror oscillograph may be employed to record the deflections on a drum.

Abstract: 598,211. Valves for preventing backnow. ABBEY, A. (Hirshstein. J.). Sept. 5, 1945, No. 22891. [Class 135] A normally open valve for preventing backflow in a sewer line comprises a disc 12 carried on one end of an arm 13, the other end of the arm being pivoted to a yoke 26 which is adjustably attached to the valve seat and has an inclined face so that the pivotal axis of the arm is inclined to the vertical to cause the valve to open under gravity immediately backflow ceases. A back-flow along the sewer closes the valve on to its seat. The disc carries a stud 16 which fits loosely through an aperture in the end of arm 13 to allow the disc to swing freely on the arm. The other end of the arm is formed with projections bored to receive pivoting bolts 20 which screw through lugs 21 projecting from the yoke and are held therein by lock-nuts - 22. The yoke carries slotted projections by which it is bolted to ears projecting from the seating flange in such manner that it can be moved in an arc-shaped path around the valve opening to vary the position of the axis on which arm 13 pivots.

Filed: 1960-06-30
Abstract: 908,587. Automatic voltage control. AUSTINLITE Ltd. May 23, 1961 [June 30, 1960], No. 22933/60. Class 38 (4). In a stand-by power supply system in which an inverter supplies an A.C. load from a battery, and in which part of the A.C. output is rectified and fed back to the battery as in Specification 796,541, the portion fed back is automatically controlled to stabilize the A.C. output voltage. The mercury-arc inverter tube V is connected to the D.C. supply through a choke L1 and an A.C. load is supplied from winding S1 on transformer T. The A.C. output voltage is applied to a comparator J, in which the A.C. voltage signal is rectified, compared with a reference Zener diode, and any error signal amplified by a transistor before being applied through a magnetic amplifier A to the control winding of a saturable reactor AW. If the A.C. output voltage rises, the saturation of reactor AW is increased so that more current is fed back from a winding S2 to the D.C. source through a rectifier MR and choke L2. The transistor amplifier of the comparator J may also be biased by a signal proportional to A.C. load current to provide current compounding. Specifications 864,923 and 864,924 are referred to.

Abstract: 282,859. Reynolds, W. A. Sept. 24, 1926. Double walls; slab walls; wall-ties; roofs; joist floors; ceilings.-In building walls or the like, slabs of concrete &c. are secured to upright or other supporting members by means of ties consisting of plates adapted to engage the slabs and fitting into split or slotted members transversely secured to the supports, the engaging members being so formed that the slabs &c. will be drawn towards the supports when the ties are moved within the slotted members. The invention is shown as applied in the construction of a hollow wall built up of tongued and grooved interlocking slabs 2, 3, secured to reinforced uprights 1. In each upright, holes 6 are formed in alignment with the divisions 7 between the slabs, and in each hole is fitted a longitudinally split tube 8, preferably of metal, a portion of the tube extending on each side of the upright. Within the slot or slots at each end of the tube is located one or a pair of ties 11, preferably consisting of steel plates. The portion of each tie within the tube 8 is formed with a rib 13, inclined as shown in Fig. 5 so as to wedge the tie in the tube. The outer end of the tie is bent down at 12, so as to engage in the groove 4 formed in the top edge of a slab. A single tie-plate may protrude through slots on both sides of the tube 8 to connect front and rear slabs to an upright; or two oppositely disposed ties may be arranged, 'as shown for example in Fig. 7, at each end of a tube 8. When uprights which are oblong in cross-section are used, they may be bored transversely in each direction, so that according to the set of holes used, the space between the faces of the wall may be made wide or narrow. The ties 11 and tubes 8 may be embedded in concrete &c. to prevent corrosion, or may be made of non-rusting material. The invention may be applied to the construction of floors, ceilings or roofs.
