Title: Improvements in and relating to electrical regenerative control apparatus and systems
IPC: H02P5/753
Filed: 1920-06-28
Abstract: 169,297. British Thomson - - Houston Co., Ltd., (General Electric Co.). June 28, 1920. Alternating-current motors; motors, controlling.-In controlling alternating-current motors bv varying the number of poles, the transitions between different pole-numbers are caused to take place at such speeds as will avoid undue. strains in working. The invention is particularly applicable to induction motors used for traction purposes, and connected to brake the load regeneratively when occasion arises. In the arrangement shown in the drawing, an induction motor 1 fed from three-phase mains 4 through a variable-ratio transformer 5 is provided with mechanical speed-responsive gear whereby four guided rods 59, 60, 61, 62 change position from left to right or vice versa when the motor passes through four critical speeds, the rod 59 responding to the lowest and the rod 62 to the highest speed. By the design of the gearing, the critical speeds are those which correspond to the points of smooth transmission from 8-pole running to 6-pole running, and from 6-pole to 4-pole, the two lower speeds referring to motoring and the two higher to braking. The Specification gives a set of characteristic curves and numerical values of the transition speeds for a particular example. The speed-responsive gear comprises an auxiliary motor 37 running without load and driving one element of each of four differential bevel gears 42, the opposite elements of the four gears being driven through bevel wheels of the designed speed ratios by a countershaft 49 from the main motor 1. The idle wheels of the differential gears are cut with cam-slots which throw over the respective rods 59 &c. at the critical points. The rods act upon a pole-selector switch 64 through a set of electromagnetic switches 84, 90, 95, electromagnetically actuated valves 75, 76, and a double-action pneumatic cylinder 65. The transitions are further governed by a manually operated pole-selector 63, which when initially set, say for 8-pole running, prevents any automatic change in the pole-number unless regenerative braking sets in; but when set for a different pole-number allows the transiticn to be effected by the automatic gear at the proper speed. The Specification describes in detail the further connections and electrical interlocks required for preventing accidental or improper pole-number transitions. In order to admit of multiple-point control, the requisite branch leads are grouped into a cable 127 extending to the other control points.

Abstract: 758,771. Aerials. BELLING & LEE, Ltd. May 31, 1955 [June 16, 1954], No. 17693/54. Class 40 (7). An aerial system intended to uperate in resonance on two frequencies, one in Television Band I and the other in Band III, comprises an element 10 half a wavelength long at the lower frequency and a " T "- type matching section for coupling the element to a transmission line 16 which matching section 11, 12, 14, 15 together with the centre part of the element 10 forms a folded dipole resonant at the higher frequency. The matching effected between the element 10 and the transmission line at the lower frequency is dependent on the dimensions of the T " matching section and if for this purpose it appears that the points of connection to the element 10 should be closer together than half a wavelength at the higher fre. quency then the end portions 14 and 15 can be loaded by the inclusion of an inductance or by extending them in the form of a loop. To increase the gain of the system at one or both frequencies appropriate parasitic director and/or reflector elements can be provided. The elements 11 and 12 may be coupled mechanically by means of an insulator 13. It is pointed out that an aerial system (Fig. 2, not shown) in which the insulator is placed in a break in the middle of element 10 with the transmission line 16 coupled at either side of the break, the rods 11 and 12 being continuous, is the electrical equivalent of the system of Fig. 1.

Abstract: 1468574 Testing containers for leaks: manometers SOC ANON DES USINES CHAUSSON 23 April 1974 [10 May 1973] 17799/74 Headings G1L and G1S A container 2, Figs. 1, 4, to be tested for leaks is pressurized and compared with a leak tight and similar reference container 1 by connecting both containers to a source of pressure gas 25 through a duct 7 and a three way distributer 6. A differential manometer 8 connected to both containers via a bulb 39 and a deformable diaphragm case 37 to indicate a possible leak when the distributer 6 is operated to isolate the containers from the pressure supply, has a light source 42 and a photo-electric liquid level reading cell 44, Fig. 3, connected to an amplifier 45 and a warning lamp or buzzer 46. The volumes of the case 37 and the bulb 39 are sufficient to contain all the liquid 36 if there is a great difference in pressure between 81 and 82. The testing gas from 7 also operates a piston 31 which closes a switch 33 and lights a.lamp 34 to indicate that the pressure is the same on both sides of the piston V in the containers 1, 2. Before the test begins however the connections 3 and 4 to the containers are made and opened automatically by pistons 17, 18, which are themselves operated by a relay 50 controlling a compressed,gas distributer 51 connected to a second gas source 7a and providing a draining off position 51a and a working position 51b. After the connections are made, the control gas from duct 7a is passed through a delaying device 56 which lets gas pass only after the connections to the containers are actually closed. After this delay period the control gas operates a relay 28 which brings distributer 6 into the working position 6b to supply test gas to the containers from duct 7 and source 25. After a further period of time, the delay device 57 opens to release relay 28 and switch the distributer 6 to a position 6a where it isolates the containers from the gas source 25 and connects them only to manometer 8. The manometer may or may not signal a leak, but at the end of the period a time switch 48 sends a signal to the relay 29 which brings the distributer 6 to its draining position 6c. In Fig. 2 (not shown) the test apparatus is shown in the form of a test bench or console with equal length flexible test gas hoses (22) (24) connected by distributing ends (23) to the special caps 4 which have gas holes 20 in their ends. Other additional caps (3a) (4a) can be provided for extra apertures in the heat exchangers (1) (2) to be tested.
