Abstract: 712,415. Cooking vessels. ROONEY, G. W. Sept. 8, 1952 [Sept. 7, 1951], No. 21149/51. Class 66 A domestic cooking vessel 1 has an inner vessel 3 supported wholly within it, the side walls of the two vessels being substantially spaced apart and one or more drainage holes 3c being provided in the inner vessel. The inner vessel may have a downwardly extending internally threaded spigot 3a projecting from the centre of its base which can be screwed on an upwardly extending threaded boss 1a provided on the bottom of the outer vessel 1. This provides a rigid support for the inner vessel and yet enables it to be detached for cleaning purposes. In another embodiment the inner vessel is supported by a spider having two or three points of contact with the edge of the pan. Preferably the ends of the spider arms have spring clips to retain the vessel 3 in the outer pan even when the latter is upended. The capacity of the'vessel 3 is made roughly equal to the volume of the outer pan up to the bottom of this vessel. When the arrangement is used for boiling milk a quantity not more than will fill the vessel 3 is poured in and heated to boiling point, it then flows upwards outside and eventually into vessel 3 which it fills. A small quantity passing through the holes 3c circulates to maintain the temperature of the whole but boiling over is stated not to occur as the bulk of the milk is out of direct contact with the heating means.

Title: Improvements in or relating to direction finding radio receiving installations
IPC: G01S1/02
Filed: 1937-08-07
Abstract: 500,481. Directive wireless signalling. MARCONI'S WIRELESS. TELEGRAPH CO., Ltd., and COCKERELL, C. S. Aug. 7, 1937, No. 21796. [Class 40 (v)] The bearing, as well as the "sense," of a distant transmitter is determined by combining the signals from a directional aerial with signals in phase-quadrature derived fromone or more non-directional aerials, under the control of a local low-frequency oscillation, and applying them to a cathode-ray indicator. As shown in Fig. 1, the input circuit of the valve 1 includes the search-coil 3 of a radiogoniometer (not shown) in series with a coil 2, the latter being coupled directly to one " open " aerial 7, and through an amplifier 8 to a second "open" aerial 10. A transformer 13 applies a 50-cycle local oscillation. The arrangement is such that the "open" aerial components are in phase-opposition with each other, and in phase-quadrature with the directive signal components, in the combining circuit 2, 3, 4, when no signals are being received. They then give the cathode-ray trace shown in Fig. 2, when the output from valve 1 is fed to one pair of deflector plates, and the local oscillations from a 50-cycle source 13 are fed to the other pair. When the directional aerial is in the minimum position, the trace takes one or other of the forms shown in Figs. 6 and 7, the " sense " being in the direction of the smaller triangle. No other manual control is necessary. Automatic volume control, having a time-period greater than that of the oscillations from 13, is applied to exclude fortuitous signals received by the " open " aerials 7, 10. In a modified arrangement each of the open aerials feeds into a variable-mu valve, the two valves being arranged in parallel as regards the valve input circuit, but in pushpull to the local oscillations, Fig. 8 (not shown). One open aerial may be used instead of two, this being connected in parallel to the grids of a pair of screen-grid or heptode valves to which the 50-cycle source is applied in pushpull, Fig. 9 (not shown). In another modification, Fig. 11 (not shown), the operation of a " sense " switch gives a trace which shows a constricted part only if the sense is correct and not otherwise.

Title: Improvements in and relating to test systems and apparatus therefor
IPC: G01M13/02
Filed: 1944-11-08
Abstract: 583,614. Control of several motors. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 8, 1944, No. 21925. Convention date, Nov. 13, 1943. [Class 38 (iii)] [Also in Groups XIX and XXXVI] A pair of gear drives are simultaneously tested by connecting them together mechanically and connecting each to a dynamo-electric machine, these machines being supplied from a generator and controlled so that there is an electrical pump back of power from one machine to the other, the losses of the system being supplied from the generator. The output shafts 11 of the differential drives 10 under test are mechanically connected together by belts or chains 12. The input shafts 13, 14 are mechanically connected to the armatures of dynamo-electric machines 15, 16 which are connected across a generator 23 driven at constant speed by a motor 24. As the excitation of one of the dynamo-electric machines is increased it tends to run slower than the other machine and mechanical power is transmitted through the gear drives. The machine with the higher excitation then becomes a generator and electrical power is transmitted from it to the machine with the weaker field. Thus, only the losses are provided by the main generator 23. Tachometer generators 54, 55 are mechanically coupled to the machines 15, 16 driven in a predetermined speed relationship to the speed of these machines, and used to control the field winding 47 of the main exciter so as to increase or decrease the output of the generator when the speed of the machines rises or falls below a predetermined value. The power developed or consumed by the dynamo-electric machines is indicated by wattmeters 27, 28. In order to assure rapid response and to provide the desired control to the machines amplidyne exciters 31, 32, 34 are provided with field exciting windings 38, 39, 40 which are connected in series with the armature to neutralize the load current component of the armature reaction. The amplidyne exciters are provided with anti-hunt field windings 41, 42, 43 connected through condensers 44, 45, 46 across the exciters. These stabilizing field windings are energized only under transient conditions and provide a component of excitation in a direction which tends to dampen out the transient conditions of the exciter. A manually operated switch 58, which has contactors 59-65, is used to control the energization of the amplidyne exciters in order to vary the amounts of loading, to reverse the direction of operation of the gears, to test the gear mesh for both directions of rotation, or to operate only one of the dynamo-electric machines, 15, 16. Specification 539,835, [Group XXXV], is referred to.
