Title: Improvements relating to induction generators
Inventor: COLLINS DEREK NORMAN
IPC: H02K17/42
Filed: 1957-07-09
Abstract: 891,482. Induction generators. VATRIC (CONTROL EQUIPMENT) Ltd. July 9, 1958 [July 9, 1957], No. 21722/57. Class 35. An induction generator has two concentric stators between which a drag-cup 3 rotates, the inner stator which carries the generating windings 5 being arranged to shunt the flux generated by the field coils 2 in the outer stator so that no voltage is generated when the cup is not rotating. Each inner pole-shoe I.P. bridges two outer pole-shoes O.P. so that when the machine is at rest the field flux traverses path m, n, o, p shown in solid lines. Rotation of the cup displaces some of the flux into the quadrature circuit q, r, s, t shown in broken lines, so that it links the generating coils 5. The inner and outer stators may be reversed. The two stators may be relatively rotated for adjustment.

Title: An improved process for the preparation of dibasic calcium hypochlorite
IPC: C01B11/06
Filed: 1943-12-29
Abstract: 574,979. Dibasic calcium hypochlorite. PENNSYLVANIA SALT MANUFACTURING CO. Dec. 29, 1943, No. 21784. Convention date, Dec. 30, 1942. [Class 1 (iii)] Dibasic calcium hypochlorite of increased crystal size and improved filtrability is produced by mixing a suspension of this compound with calcium hydroxide, powdered or suspended in water or hypochlorite solution, and adding hypochlorite ions sufficient to substantially convert the lime to dibasic hypochlorite but insufficient to form appreciable amounts of less basic calcium hypochlorite. The initial suspension may be produced by treating a calcium hydroxide suspension with hypochlorite ions. Hypochlorite may be added in both stages as solution, suspension, or as chlorine gas-preferably at a moderate rate, e.g., 0.5 to 2.5 per cent. of the theoretical chlorine equivalent per minute. Waste hypochlorite solutions may be utilized. The ratio of initial to final dibasic hypochlorite is not less than 0.1 and is preferably 0.15 to 0.75 or sometimes higher. To avoid precipitation of less basic compounds the temperature should not be below 25 ‹C. It is preferably 30- 40‹C. but may be higher provided decomposition is not excessive. Cooling is provided if necessary. The process may be repeated until excessive nucleation sets in owing to the decrease of crystal area per unit weight. The addition of salt up to saturation content, preferably just before separation of the crystals from the solution so as not to impair crystal growth, but if desirable at any previous stage, results in increased yields, provided sufficient calcium hydroxide is present to react with the calcium hypochlorite salted out. Examples of operation are given, the stated yields being 60- 95 per cent.

Abstract: 1,087,823. Crimpable filaments. FARBWERKE HOECHST A.G. May 24, 1965 [May 26, 1964], No. 21886/65. Heading B5B. Three-dimensionally crimpable filaments are made by introducing at least two streams, which differ only in temperature, of a linear polymer, each of a homogeneous melt, to an extrusion nozzle and withdrawing the filaments therefrom. The streams of linear polymer may have been melted in melting devices maintained at different temperatures (Fig. 1), or in the same melting device, but divided into partial streams conveyed to the nozzle in conveying means maintained at different temperatures (Fig. 2). The difference in temperature between the hottest or hotter and the coolest or cooler stream is preferably 5-35 C. and desirably 10-15 C. The streams are suitably combined in a common nozzle hole at the end of the nozzle from which the filament is withdrawn, (Fig. 3). The nozzle holes may be of any desired shape, e.g. of circular, elliptic, T- or Y-shaped, starshaped, or triangular cross-section, and are advantageously of rectangular cross-section. Filaments so made are crimped by subjection to temperatures of 120-180 C. for 1-5 mins. while the filament is free from tension. Specified materials include polyamides, polyesters and polyolefins.

Filed: 1969-04-30
Abstract: 1,224,454. Angular bending. DOMINION BRIDGE CO. Ltd. 30 April, 1969 [4 March, 1969], No. 21946/69. Heading B3E. A method of forming an elongate trough member from an elongate planar workpiece comprises applying opposing forces to the longitudinal edges of the workpiece in a direction inward of the edges and at right angles to the edges to move the edges towards each other, and constraining the edges to move in a common plane. In one embodiment a workpiece 11, having an initial upward prebend, is inserted between pressure plates 8 and 9 and is bent by moving guides 6 toward pressure plate 8 by means of an hydraulic piston and cylinder assembly 10. An adjustable limit switch 15 is provided to limit the inward movement of the guides 6. In a second embodiment a workpiece 31 is inserted between pressure plates 20 and guides 23 are moved towards each other by means of transverse right- and left-handed screws 24. As the initial compressive force is imparted to the workpiece, jacks 30 engage the central mid-portion of the workpiece causing it to bow upwardly, thus causing jaws 25 to pivot about pins 26. In a third embodiment, a workpiece 56 is placed between pressure plates 49 and 58 in a plane eccentric to the plane of pivot pins 48 and 68 so that upon initial application of a force by means of chains 63 an upward force will be generated so avoiding the use of jacks or an initial prebend. An air hose 65 assists in the initial movement when a heavy load is required to bend the workpiece.

Abstract: 222,298. Marks, E. C. R., (Ateliers de Construction de Chaudronnerie et d'Estampage d'Awans Soc. Anon.). Sept. 4, 1923. Charging. - A skip for charging blast furnaces is provided with a cover at the point of coupling to the hoisting mechanisms, and means are provided for maintaining the cover in a slightly raised position when the whole weight of the skip is taken by its bottom, the cover closing, under its own weight, when the weight of the skip is taken by the furnace throat. As shown, the hoisting cables 1 act, through pulleys 2, 2<1>, on a cross-piece 3 connected to a frame 5 through the medium of springs 4 and attached, by a rocking-beam 13 and pivoted links 18, 18<1>, to arms 14, 14<1> which are pivoted to the frame 5 and carry at their outer ends cables 15 supporting the cover 12. Sleeves 20 are provided inside the springs 4 to limit their compression. Fig. 1 shows the skip being raised, the whole weight being taken by the movable bottom 11; the springs 4 are consequently compressed to their limit and the cover 12, which is guided by the rod 6, is retained in a slightly raised position. Immediately the skip is seated on the furnace throat and its weight taken thereby, the springs 4 expand and the cross-piece 3 moving downwardly causes similar movement of the outer ends of the arms 14, 14<1> to lower the cover on to the skip. Further lowering of the frame 5 causes the bell 11 to descend so that the contents of the skip are discharged, the cover 12, during discharge, remaining seated on the skip.

Title: Improvements in electrically-driven web-winding equipment
IPC: B65H23/195
Filed: 1945-08-30
Abstract: 603,723. Automatic control systems for winding equipment. MASON, F. R., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 30, 1945, No. 22373. [Class 38 (iv)] In web-winding equipment, constant linear speed of the web is maintained automatically, by control of the motor and associated generator excitations. The web W is wound on reel B by the D.C. motor D, the armature DA of which is in series with armature GA of generator G, driven by three-phase motor M from supply mains L. Separately excited fields DF, and GF of motor D and generator G respectively, are in series with constant voltage exciter E. A metadyne exciter A is connected across the field GF with the control excitation provided by opposing fields AR, in parallel with rheostat R across exciter E, and AV, supplied from tachometer generator T, the output of which is a measure of the web speed being driven therefrom. The armatures of generators E and A are driven from motor M. Closure of push-button S starts motor M, by energizing contacted coil CC, to close contacts C, in line L, and the holding contact CA. A normally closed stop switch breaks both of these circuits. Contact RI is closed so as to permit starting-up of motor M only when rheostat R is in the position of minimum reference voltage across field AR. The winding operation is commenced by closure of contacts C to start motor M and generator G. Initially, the voltage generated by metadyne A is zero, the armature AA effectively short-circuits field GF, and the output voltage of exciter E is applied to the field DF. Operation of rheostat R to increase the metadyne excitation, and consequently the output voltage, raises the voltage applied to the field GF and reduces that across field DF. Reel motor D starts and the speed rises progressively as rheostat R is operated. At the desired speed the opposing fields AV, AR balance substantially and as the radius RR increases the tachometer generator T speed rises and thus raises the excitation of field AV, reduces the excitation of field GF and raises that of DF so lowering the speed of reelmotor D to ensure constant linear speed of the web. An electromagnetic brake, applied to reel driving motor D, is released on the supply being made to motor M.
