Title: Improvements in Electric Switches.
Inventor: ABEGG EDUARD
IPC: H01H19/10
Filed: 1918-12-31
Abstract: 136,918. Abegg, E. Dec. 31, 1918. Quick-action switches. - In a rotary switch, the quick action is produced by straining and relaxing a soft material having about the same elasticity as rubber, and connected with the contact member and the operating-member. In the construction shown in Fig. 1, the handle 3 drives the spindle 4, which has a one-way connexion with the plate 11 fixed on the upper face of the cylindrical resilient block 10, which is free on the spindle and has the contact member with the contacts 18 secured on its lower face. The resilient member may be reinforced by a coiled spring 16 surrounding it. The contact member takes a bearing on a plate 8 secured to a projection of the switch base, and the plate has recesses engaged by projections on the contact member to hold the contact member until the resilient member is sufficiently strained, when the contact member is lifted slightly and escapes from the detaining- means, and the resilient member carries it round rapidly. The bow-shaped bridging-contacts consist each of a number of plate segments with upturned ends 18 passing through an insulating plate on the end of the contact member and secured by pins 20. One of the outside plates 17 is longer than the others and engages the side of the fixed contact, so that a slow break of contact does not result when the contact member is lifted slightly preparatory to the rapid action. As applied to a lamp-holder, Fig. 3, the movable contacts 27 are carried by pieces 28 of the resilient material and are forced into engagement with the fixed contacts 26 when the rectangular member 29 on the operating-handle is rotated. With further rotation, the resilient pieces produce a quick break.

Title: Improvements in or relating to hydraulic turbines
Inventor: KERENSKY GLEB
IPC: F03B15/20
Filed: 1959-06-26
Abstract: 949,772. Fluid-pressure servomotor control systems. ENGLISH ELECTRIC CO. Ltd. Feb. 16, 1960 [June 26, 1959], No. 22045/59. Divided out of 937, 653. Heading G3P. [Also in Division F1] A hydraulic turbine is provided with conventional primary quantity controlling mechanism as described in Specification 937,653 and secondary regulating means in the form of a relief valve at the turbine end of the penstock, both mechanisms being under the control of a turbine speed governor. The relief valve 108 is actuated by a control valve 105 which on opening relieves pressure from a space 106 to allow the valve to open under the action of pressure in the space 107. The valve 105 is controlled by the governor acting through a lever 101 and a dashpot 102,103 on a cam 104. The valve 108 closes under the collapsing effect of the dashpot which is provided by leakage through passage 112 and restriction 111. Towards the end of the closing movement of the valve 108, the passage 112 is closed by a valve 113 and the closing movement is retarded by the leakage being restricted by a restriction 114 or leakage past the valve 113. Thus for small movements of the governor,the valve 108 is actuated due to this reduction of the reclosing action of the valve. In a modification the by-pass round the dashpot is closed completely during opening movements of the valve 108. In a further modification, the dashpot is springloaded so that the relief valve is normally held in a partly open position.

Title: Non-reciprocal component with a wide band slot line
IPC: H01P1/38
Filed: 1974-05-17
Abstract: 1470789 Isolators and circulators LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 17 May 1974 [18 May 1973] 22102/74 Heading H1W A non-reciprocal microwave device, e.g. an isolator or circulator, comprises a slot-line disposed directly or indirectly upon a plate of gyromagnetic material having a thickness greater than three times the width of the slot and subject to a transverse magnetic field parallel to the plane of the line and of an intensity substatially below that necessary to produce gyromagnetic resonance. The device operates by field-displacement, wave-energy travelling in the "forward" direction being concentrated near the plane of the slot-line and wave-energy travelling in the "reverse" direction being concentrated near the plane of the gyromagnetic plate remote from the slot-line. Thus, in the isolator of Fig. 2 (a) where a slot-line 1, 1<SP>1</SP> is directly disposed on a gyromagnetic plate 5, forward-travelling waves are transmitted without attenuation whilst reverse waves are absorbed in a dissipative pad 6 attached to the exposed face of the plate 5. Input and output means of the slot-line may be in the form of coaxial connection 3<SP>1</SP> (one shown) axially spaced along the line. In a modification (Fig. 7, not shown), a layer of low-loss non-magnetic, dielectric material is interposed between the slotline and the plate 5. The thickness of this layer is less than twice the slot width w. The pad 6 may consist of dissipative gyromagnetic material. In the modification of Fig. 11, the pad 6 is eliminated and reverse attenuation obtained by subjecting part of the gyromagnetic plate 5 remote from the slot-line to a field H<SP>1</SP> of value sufficient to cause energy dissipation. Fig. 9 shows a 3-dimensional view of a circulator in which both faces of the gyromagnetic plate 5 are provided with slot-lines and four ports are provided in the form of coaxial connectors 91, 92, 93, 94. Circulation between the ports in the order set forth is obtained by virtue of the fielddisplacement effect above described.
