Title: Improvements in Electric Switches or Circuit Interrupters.
IPC: H01H3/32
Filed: 1918-11-19
Abstract: 134,376. Coates, W. A., Dale, W. B., and British Westinghouse Electric & Manufacturing Co. Nov. 19, 1918. Automatic circuit-breakers; electro-magnetic switches.-In automatic circuit-breakers of the loose-handle type in which the operating-handle, or its power-operated equivalent, is connected to the switch-actuating mechanism through a hooked catch which is disconnected (when abnormal conditions arise) by an electro-magnetic tripping device, the catch and tripping device are so arranged that the operative point of connexion of the tripping-means with the catch remains at the same distance from the catch throughout the whole range of movement of the catch during the closing operation of the switch, so that the switch can be tripped equally well at any point in the path of movement of the operating-lever. As shown in Fig. 1, applied to a circuit-breaker electro-magnetically operated by the solenoid plunger 12 through toggle-links 8, 9 and an operating-lever 11 connected between the plunger and the fixed pivot 10 of the toggle, the catch 13 pivoted at the toggle joint is connected by a link 18 to the operative end of the tripping-armature 16 at the point 19 which is co-axial with the fixed pivot of the toggle. Consequently, throughout the closing movement of the switch, the pivot 19 remains unmoved until the tripping-armature is attracted, whereupon the movement of the pivot 19 is transmitted through the link 18 to the catch which releases the toggle linkage, thereby allowing the switch to resume its ' off ' position, under gravity. The operating-lever is raised by the spring 20 to restore the catch into engagement with the pin 15,. if the abnormal conditions have ceased. When the switch has been brought to the closed position by the plunger, it is held there (so that the closing electro-magnet may be de-energized) by a spring detent 21 which may be manually released to trip the switch. The pivoted armature 16 and the link 18 may be replaced by a solenoid core having a flexible connexion passing through an orifice in the fixed pivot of the toggle mechanism and connected with the catch 13. In the construction shown in Fig. 3, the main switch lever 3 is operated by an intermediate lever 29 pivoted at the same point 27 as the operating- lever 26 and connected thereto by a. catch 32. During the closing movement, the cable moves in close proximity to the surface 38, concentric with the pivot 27, of a bar 35 which is connected with the tripping armature 16 so that, when the surface is moved parallel to itself towards the centre by the operation of the armature, the switch is tripped equally at whatever points has been reached in the closing movement.

Title: Improvements in and relating to thermionic valves and circuits
IPC: H03K4/28
Filed: 1950-07-31
Abstract: 690,438. Thermionic valves. HARRIES, J. H. O. July 9, 1951 [July 31, 1950], No. 19004/50. Class 39(i). [Also in Group XL(c)] A thermionic valve is provided with an element or elements of lossy dielectric material in the electric fields between two or more of the conductors forming the electrode assembly, the material of the elements having a power factor sufficient to substantially increase the power factor between the conductors when the elements are inserted between the conductors, the elements being so arranged that they do not conductively bridge the gap between the conductors. The dielectric elements d may be secured within the beam-forming plates p of a beam tetrode and the screen grid sq may be provided with fins f to increase the capacity; in a tetrode without beam forming plates, Fig. 5 (not shown), the elements may be secured to fins on the screen grid. In another construction, Fig. 3 (not shown), the elements are mounted on the beam forming plates of a beam, tetrode on the sides facing the anode. The elements serve to damp out oscillations which may be caused if the anode goes negative and preferably have a power factor greater than 0.1. They may comprise particles of carbon, iron, copper, nickel, or silicon carbide bonded together by a ceramic binding material, or may be of the ceramic known as " polyiron", and they may be enclosed in glass tubes. The material may be applied in liquid form on to an electrode as a series of layers, and baked after each layer has been deposited. The Provisional Specification states that the dielectric material may be an impure ceramic material of high power factor, or may be of carborundum, lead oxide or other conductors in a glass, ceramic or other suitable bond.

Title: Improvements in and relating to electric circuit breakers
Inventor: ATHERTON THOMAS GEOFFREY FENTO
IPC: H01H73/50
Filed: 1955-07-01
Abstract: 784,006. Automatic circuit-breakers. DORMAN & SMITH, Ltd. Feb. 14, 1956 [July 1, 1955], No. 19037/55. Class 38 (5). A circuit-breaker comprises an insulating case 9 with a detachable side (not shown), an opening 13 in the top for an operating handle 14 and openings through which terminals 15 project, a pivoted moving contact arm 23 connected by linkage 22, 20 to the handle 14, a bimetal strip 41 in series with the contact arm, a pivoted member 30 on which the link 22 is fulcrumed, and a trip member 34 which under overload or short-circuit conditions is moved out of a position in which it normally supports the pivoted member 30. Under normal conditions, movement of the handle 14 causes the link 22 to pivot about its fulcrum on the member 30 to open or close the contacts 23, 26, the pivot 21 between the links 20, 22 moving in arcuate slots 25 formed in the casing and side concentric with the fulcrum point. In the event of overload, the bi-metal 41 acting through an adjusting screw 42 turns the trip member 34 to move a projection 33 of the member 34 out of engagement with the member 30 and the member 30 is moved from under the link 22. A spring 24 now turns the link 22 and the contact arm 23 about the pivot 21 to open the contacts. As the arm 23 rotates, it strikes the linkage knocking it back over centre to return the handle to the off position, the circuit-breaker being automatically reset as springs 36, 44 restore the members 34, 30. In the event of a short-circuit, an iron channel-shaped member 37 is magnetized by the current in the bi-metal strip and attracts the trip member 34 to produce tripping in the manner described above. The member 37 is pivotally mounted for adjustment purposes only.

Title: Improvements in or relating to ultra high frequency apparatus
IPC: H03C3/28
Filed: 1938-06-28
Abstract: 504,238. Modulating - - apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 28, 1938, No. 19177. Convention date, July 28,1937. [Classes 40 (iii) and 40 (v)] Modulation of an ultra high frequency is effected by varying, in accordance with the modulation, a resonant line which is employed for stabilization of the oscillator. The outer or inner member 15 or 17 of the concentric resonant line 13 is made of magnetostrictive material, and modulation currents from source 23 applied to the solenoid 21 vary the effective length of the line by varying the capacity between the armature 19 and the end of the outer member 15 and, in consequence, the frequency of the oscillator 25 which is coupled to the line is modulated. The member 15 may be slotted to reduce eddy currents. The diaphragm at the end of the line may be bi-metallic, one of the metals being magneto-strictive, Fig. 3 (not shown). A solenoid energized by modulation currents is placed adjacent the diaphragm which bulges and so varies the effective capacity of the line. The Specification as open to inspection under Sect. 91 comprises also an arrangement in. which the diaphragm is not magneto-strictive and is influenced by a solenoid. carrying an intermediate carrier frequency, amplitude modulated with the signals. Reaction between the magnetic field and eddy current in the diaphragm produce movement of the diaphragm which, however, due to its inertia, is only able to follow the signal frequency variations. In another arrangement, a piezo-electric crystal, whose dimensions are varied by modulating potentials, is employed to vary the capacity between the inner and outer members of the line ; or the end of the outer member of the line may comprise an acoustic diaphragm upon which sound waves are impressed directly. The invention is applicable to the control of the local oscillator of a superheterodyne radio receiver employing automatic tuning; and may be applied to vary the coupling between an oscillator and its load to obtain amplitude modulation. This subject-matter does not appear in the Specification as accepted.
