Title: Improvements in and relating to electric controlling and regulating systems
IPC: G05F1/00
Filed: 1932-12-16
Abstract: 413,634. Control systems for consuming devices; automatic control of A.C. voltage; protective arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Nixdorff, S. P. ; 18, Hampton Avenue, and Alexanderson, E. F. W. ; 8, Adams Road, both in Schenectady, New York, U.S.A.) Dec. 16, 1932, No. 35753. Convention date, Dec. 16, 1931. [Classes 38 (ii) and 38 (iv).] Phase changing.-In order to control or regulate an alternating current circuit a discontinuous-control, or vapour-filled, electric valve energized from the circuit has its grid circuit subjected to a potential which is modified by a saturable reactor, the reactance of which varies with the output of the valve, so that the valve oscillates between fully conducting and non-conducting conditions. The reactor may be used as a series reactance, the average value of which determines the current or voltage in the A.C. circuit. In a further modification, for maintaining a generator in phase with a network from which it has been disconnected, the reactor is used as an element in a phaseshifting circuit supplying the grid potential. Fig. 1 shows the invention applied to control the current in an A.C. circuit, in particular the starting, stopping, or speed control a commutator motor 10, in accordance with the operation of a phase-shifting transformer 25 which, with a phase-shifting circuit 21, 22 determines the phase relation between grid and anode potentials of valves 16, 17. When anode current flows the windings 14, 15 saturate the reactors 12, 13 and the voltage applied to the phase-shifting circuit dies away, so that the grid voltage vector shifts in relation to the anode voltage vector and the valves become suddenly nonconducting, whereupon the cycle recommences. The average value of the series reactance in the A.C. circuit will depend upon the setting of the phase-shifting transformer 25. Fig. 3 shows the automatic regulation of A.C. voltage of load circuit 11. This voltage is applied, through an amplifying resistance-bridge 30 and a rectifier and filter circuit, as a unidirectional voltage bias in series with the voltage applied to the grids of the valves by a phase-shifting circuit 21, 22 which, as in Fig. 1, is subject to the voltage across the series reactances 12, 13 which become saturated when the valves conduct. Fig. 5 shows saturable reactances 53 in a phase-shifting circuit energized from a supply network 41 and normally arranged to render the valves 46, 47 nonconducting. Should the circuit breaker 42 open and a phase difference occur between the generator 40 supplying the anodes and the network 41 supplying the grids of the valves, these are rendered intermittently conducting to apply by means of the resistance 44 an average load compensating for the load lost by the disconnection of the network and preventing loss of synchronism.

Title: Improvements in or relating to methods of making panels for women's garments
IPC: A41B9/00
Filed: 1959-10-22
Abstract: 903,643. Knitting-machines. GORDON, B. D. Oct. 22, 1959 [Feb. 2, 1959], No. 35826/59. Class 74 (2). Breast cups for a swimsuit or brassiere described in Specification 903,644 are fashioned on a fully fashioning machine by backracking of the fashioning points after the completion of each course so that continuous transfer of loops from the same needles in a widening direction is achieved. The needles effecting this fashioning form a group on one side of the centre-line of the cup. This effect is illustrated by the group AA<SP>1 </SP>in Fig. 1 and the eyelet formation created by widening movement of the transfer points is shown by the line A<SP>1</SP>B<SP>1</SP> in Fig. 1 or EF in Fig. 3, which occurs in a single wale. During the above loop transferring operation on one side of the fabric a normal loop transferring operation is made on the other side after the completion of each course so as to widen the fabric and create a line of openings A<SP>1</SP>1<SP>11</SP> or E<SP>1</SP>F<SP>1</SP> which extend across the fabric. After the widening operation a few courses are knitted during which the transfer points are not operated and subsequently the transfer points are given reverse movements to narrow the fabric. The front of the swimsuit or brassiere is knitted in two separate halves which are subsequently sewn together along their inner selvedges at 24.

Abstract: 172,871. Anderson, R. W. Dec. 29, 1920. Non-conducting coverings for heat.-In order to secure a heat-insulating covering 8, Fig. 2, to ships' bulkheads or similar surfaces 1 from which project stiffeners or like abutments 3 without the necessity of perforating the bulkhead 1, sheets of expanded metal or other metallic mesh 9 are placed over the insulation 8 and are drawn up tightly against it by means of a number of bars 10 placed exterior to the mesh 9 and engaged by bolts 5 and nuts 11 or similar tightening-means carried by the stiffeners 3. In the construction shown in Fig. 2, the web 2 of the stiffener is of greater depth than the insulation 8 and a local insulation 8a held in place by expanded metal 9<a> laced to the mesh 9 is necessary to cover the projecting portion of the web 2. Such local insulation 8<a> may also be held in place by lengthening the bolts 5, or, as shown in Fig. 8, by the use of auxiliary eye-bolts 13 mounted on the bolts 5 and co-operating with a second series of rods 15. When the web 2 is of less depth than the insulation 8, no local insulation 8a is necessary, and, in some cases, where the stiffener 3 has a flange 2a, it may be necessary to perforate this flange 2a, as shown in Fig. 20, for the passage of the eye-bolts 20. In the modification shown in Fig. 18, the web 2<c> is of great depth and two flanges 2a are provided, the insulation 8, 8<b> and 8<c> being secured in position by means of the meshes 9, 9b and 9<c> and co-operating bars 10, 18<a>, and 18.

Abstract: 1320608 Change-speed gearing DAIMLERBENZ AG 4 Aug 1971 [4 Aug 1970] 36599/71 Heading F2D Change-speed gearing having at least three speeds has hydrodynamic and force-engaged coupling units so arranged that under drive gear change is exclusively effected by charging and/or discharging the hydrodynamic units and release of appropriate coupling units which are only engaged when they are not under drive. There are less hydrodynamic units than gear changes effected as parts at least thereof serve a plurality of changes. In Fig. 1 a drive shaft 10 acts through a converter 11 and gearing comprising hydrodynamic couplings 14, 15 and epicyclic gearings 20-22 having force-engaged coupling unit brakes 24-26 to drive an output shaft 23. The brake 26 is used to engage reverse gear. In first gear couplings 14, 15 are empty and brakes 24, 25 are engaged, drive then being directly from the shaft 12 through all the gearings 20- 22 to the output shaft 23. Release of the brake 24 and filling of first coupling 14 and then coupling 15 above eliminates gearings 20, 21 successively from the drive while subsequent release of brake 25 and filling of both coupling 14, 15 causes gears 21 and 22 to rotate as a unit to drive shaft 23 directly. Thus in each gear change the brakes are only released and when in the reverse gear changes they are re-engaged this occurs when they are not being driven. In Fig. 1 a clutch 127 is provided to bridge the couplings 14, 15 to drive the gearing 120-122 directly and in Fig. 7 a coupling 230-232 is associated with each gearing 220-222 so that with brakes 233-235 applied and all the couplings empty a mechanical drive is provided and a further seven speeds are obtained by consecutively releasing a brake and filling a coupling.
