Title: Improvements in and relating to angular motion transmitting apparatus
IPC: G08C19/38
Filed: 1947-08-01
Abstract: 639,475. Dynamoelectric machines. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 1, 1947, No. 21098. Convention date, Aug. 1, 1946. [Class 35] [Also in Group XXXVIII] The rotor of a resultant field type receiver is wound like the armature of a D.C. machine and is fed through a commutator so that it runs continuously when its field and that of the stator are out of alignment. The rotor is geared to the stator, Fig. 1 (not shown) or to the brush-holder, Fig. 2 (not shown), or to the rotor 37, Fig. 3, of an intermediate Selsyn instrument so as to restore alignment when the direction of the stator field or, as shown in Fig. 6, of the rotor field, is changed by the 'operation of a Selsyn transmitter of conventional type. In the arrangements of Figs. 1 to 3, two auxiliary brushes may be added to the rotor for improving the torque and reducing hunting, either by shorting the two auxiliary brushes, when they must be perpendicular to the main brushes, or by connecting each auxiliary brush to one main brush. In the arrangement shown in Fig. 6 the single phase winding 7a is wound on two salient poles 5a, the polyphase winding, comprising the armature being fed by brushes 14c, 14d, 14e, and rotating the field winding 7a through gearing. The system contains an automatic repeat-back feature, in that if the receiver rotor does not achieve the correct alignment of the receiver fields, the transmitter rotor does not stay in its moved position.

Abstract: 959,891. Textile treating apparatus. ELASTIC FABRIC CO. June 16,1960 [June 16, 1959], No. 21267/60. Heading D1L. A plurality of strips of fabric are treated so as to provide the fabric with a high degree of stretchability and elasticity by feeding the strips of fabric from separate reels over a common roller to form a composite multilayer strip, continuously feeding the composite strip in a free loop form through a shrinking fluid bath at a rate sufficient to prevent any shrinking of the fabric in the bath, and supporting the composite strip in such a manner as to permit its unrestricted shrinking in all directions as it is fed from the bath. The strip may be supported on a vibratory conveyer while it shrinks, the shrinking bath may be caustic and the composite strip may be washed and coloured. Referring to Fig. 1 a plurality of reels 8, 9, 10 and 11 carry identical fabrics which are brought together and passed between rollers 21 and 22 the degree of wrap-round roller 22 being adjustable by weight 28 and then in the form of a tensionless free loop under follower roller 42,between rollers 30 and 31 where excess solution is removed and finally on to a conveyer 50 which may be isolated so that the fabric shrinks in an unrestricted manner. Rollers 22 and 31 are coupled to a motor 32 and the follower roller is arranged to reduce via an electrical circuit the speed of roller 31 when the free loop grows too small.

Title: Power storing mechanism for planing and other machine tool tables with a reversing movement
IPC: B23Q1/00
Filed: 1953-08-05
Abstract: 747,349. Planing-machines. LIBGOTTE, L. F. Aug. 5, 1953, No. 21562/53. Class 83 (3). Power-storing mechanism for planing &c. reversing machine-tables comprises means for braking the table at the end of a quick-return movement and storing the kinetic energy during the working stroke, the stored energy being released for the next quick-return run. In a planing-machine, a buffer-system comprising telescoping tubes 1, 2, is supported beneath the table by brackets 15, 16. Stop-members 4, 4A, and 5, 5A, Figs. 4 and 6, contain the buffer system, and guide it in the case of heavy planing-machines. Springs or rubber blocks may be used within the buffer. On movement of the table to the right, Fig. 6, on a quickreturn, an extension of the buffer 2 strikes a stop 9 adjustably secured to the machine frame and the buffer system is thereby compressed between this stop and the table stops 4, 4A. At the end of this movement a pair of spring latchmembers 11, 12, Fig. 2, clip over the end of a collar 19 secured to the buffer part 1. Energy of the braking action on the table is thus stored in the buffer which remains compressed during the working stroke. At the end of the latter a sleeve 7 carrying a wedge 14 strikes a further stop 10, Fig. 8. The wedge slightly compresses the buffer through a collar 13 and releases the latch members allowing the energy in the buffer to assist on the quick-return motion. Specification 711,183 is referred to'.

IPC: H01M8/04089
Filed: 1966-05-16
Abstract: 1148935 Fuel cells BROWN BOVERI & CO Ltd 16 May 1966 [19 May 1965] 21650/66 Headings G3 and R4 The voltage of the last cell or last two cells of a battery of solid electrolyte fuel cells fed serially with fuel gas is compared with a reference voltage and the difference used to control a fuel-flow regulator so that the supply of gas to the last cell or cells is the maximum consistent with complete fuel utilization. The reference voltage may be an auxiliary battery, a potentiometer in parallel with the load resistance or one of the central cells of the battery. The regulator may be a motor-driven needle valve or a solid electrolyte cell fed with the voltage difference of the cell or cells and the reference source. Gaseous oxygen is generated or used up depending on the direction of the voltage and the ensuing oxygen pressure change drives a piston along a porous cylinder through which the gas is supplied. The electrolyte of the cells may be ZrO 2  and Y 2 O 3 .

Abstract: 700,258. Control of A.C. motors. SIEMENS SOC. VER AZIONI. Sept. 18, 1951. No. 21930/51. Class 38(3) A split phase induction motor is started by closure of a switch 1 to pass a heavy current through the motor main winding 3 and through a winding-section 4 of an electromagnetic relay I. Contacts 7, 8, are thereby closed to energize the motor starting winding 6 until (under normal operating conditions) the motor current reaches its running value and the armature 5 drops. If the motor fails to start, however, a bimetallic strip 9 of relay II becomes effective to close contacts 10, 11, so energizing another winding-section 12 of the relay I. Since the fluxes due to the winding- sections 4, 12, are in opposition and are substantially equal, the armature 5 drops to disconnect the motor winding 6. An overload relay III may be provided.
