Title: Improvements in or relating to electric power switches
IPC: H01H33/75
Filed: 1931-07-02
Abstract: 379,804. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. July 2, 1931, No. 19155. Convention date, July 3, 1930. [Class 38 (v).] In a switch of the "expansion" type, in order to ensure that adequate vapour pressure is developed by the arc so that when the pressure is relieved the vapour expansion will be sufficient to ensure de-ionization of the arc path between the contacts 21, 22 immersed in water or oil, the cover 14 of the pressure chamber 10 is held down by springs 17, 18 and when raised opens up a large peripheral passage for the expansion. In addition, the cover has a depending flange portion 19 so that when it has been raised slightly the flange passes beyond the inner edge of the container thereby exposing an additional area of the cover to the pressure developed in the container and ensuring that the cover does not return until the pressure has decreased substantially. In an alternative construction, the pressure chamber is yieldingly mounted on a base within an exhaust chamber containing liquid and communicating with the pressure chamber. When the necessary pressure is developed, the chamber is lifted to allow the expansion to take place. As shown in Fig. 3, the expansion chamber (containing liquid and immersed in liquid) is made up of an insulating cylinder surrounding the fixed contact fixed to the base and carrying, fixed to its upper end, an insulating ring 43. Above the ring 43 a nest of rings 49 is arranged with orifices to admit the pluglike contact and with spacing rings 44 between. The whole structure is held together by spring bolts between upper and lower endplates 50, 41. In the case of rupture of heavy currents an adequate pressure is developed at the lower end of the chamber by a short arc and the lower ring 49, together with all above it, is lifted against the action of the springs 59, 60. This leaves two passages above and below the lowest spacing rings 44 for the expansion and provides for the additional pressure surface to prevent premature return of the rings to the normal position. With less heavy currents, a longer arc is necessary to develop the pressure which is no longer confined to the lower part of the chamber and is effective to separate the upper rings and thereby provide additional spaces for the expansion.

Title: Improvements in linear dimension gauges
IPC: G01B3/22
Filed: 1939-07-01
Abstract: 530,231. Linear-dimension gauges. STEVENS, A. H. (Sheffield Gage Corporation). July 1, 1939, No. 19219. [Class 106 (ii)] Gauging elements 13, 14 project through a table 11 or arbor at substantially right angles thereto, and motion transmitting means 42 operatively connected to an indicating device and to one of said gauging elements are yieldingly supported on the other gauging element. The posts 13, 14 project upwardly through a slot in the table and have gauging points 15, 16. The post 13 is fixed to a bar 22 carried by parallel leaf springs 26 from a block 29 secured to a plate 30 bolted to a wall 32 of the housing. The post 14 is fixed to a saddle 49 carried on a bar 35 supported by leaf springs 39 secured to the plate 30. The end of the bar 35 next the indicating means is of goose-neck form 36. The transmitting means comprising a block or lever 40 having a horizontal contact surface 41 engaging the plunger 17 of a dial indicator. The block is carried by flexible spring blades 42 at preferably 90 degrees secured to the end 23 of bar 22. Any horizontal movement of bar 35 is transmitted through the contact point 44 with a corresponding vertical movement of the plunger 17, but horizontal movement of the bar 22 is not transmitted. Thus only relative movements of bars 22, 35 are transmitted. A stationary pin 45 passes with suitable clearance through a hole 46 in the block 40 and limits swinging movement of the block. The post 14 is manually adjustable on the bar 35 by means of a screw 56 and half nut carried by the saddle, the screw being turned through bevel gear from a button 52 and the movement locked after adjustment by operating handle 63, For rapid adjustment the half nut may be disengaged from the screw by pulling on a knob 66 when the post 14 may be moved by hand. The table 11 may be moved vertically by rack gear operated from handle 78<SP>1</SP>. In a modification two pins pass diametrically through opposite holes in a hollow arbor and are respectively carried by blocks, one of which is supported by a pair of parallel spring blades and the other by the first block being connected to it by two blades at right angles. This block carries an anvil engaging the plunger of the indicator which moves a target to throw a shadow on the scale.

Title: Turbofan engines
Inventor: NEITZEL ROBERT ERVIN
IPC: F02K1/38
Filed: 1969-04-15
Abstract: 1,270,434. Gas turbine ducted fan engines. GENERAL ELECTRIC CO; April 15, 1969, No.19238/69. Heading F1J. The invention relates to a method of operating a gas turbine ducted fan engine in which at least a portion of the hot gas stream and at least a portion of the fan air stream are mixed before discharge from a common nozzle. The rate of rotation of the fan is adjustable also the energy level of the hot gas stream is adjustable and in accordance with the invention the rate of rotation of the fan is reduced and the energy level of the hot gas stream is increased substantially simultaneously whereby a desired propulsive thrust is maintained while effecting a reduction in the overall noise generated by the engine. The invention is described with reference to an engine as described in Specification 1,258,331. The back pressure on the turbine (14) which drives the fan (16) is increased by closing the flap valves (48) of the exhaust gas chutes (34) of the mixer (30) thereby reducing the rate of rotation of the fan. The pressure drop across the fan-driving turbine (14) is further decreased by opening the valves (62) whereby a portion of the hot gas stream is diverted from the fan-driving turbine into the fan air duct (22). The energy level of the hot gas stream may be increased by increasing the rate of fuel flow to the combustion equipment.

Abstract: 1,079,277. Transistor bi-stable circuits. STANDARD TELEPHONES & CABLES Ltd. May 7, 1965, No. 19345/65. Addition to 905,285. Heading H3T. In a bi-stable circuit of the form described in Specification 905,285, in which a pair of remanent magnetic cores remember the state of the circuit in the event of power supply failure, each core is provided with a third winding coupled to the control electrode of the appropriate electronic switching device. As shown, assuming NPN transistor Tr1 is conductive and Tr2 is non-conductive, core K1 is biased to a positive saturation state by premagnetizing current via NPN transistor Tr3 and core K2 is additionally biased to a stronger positive saturation by the collector current of transistor Tr2. In the event of failure of the supply voltage, the current of transistor Tr3 is arranged to decay more rapidly than that in the other transistors hence core K1 is switched to negative saturation. Upon restoration of the supply voltage, core K1 is restored to positive saturation, a pulse induced in winding 3 turning off Tr2 and restoring the circuit to its original state which may be reversed by signals at P1 or P2. Diodes D1, D2 prevent switching of Tr1, Tr2 upon disconnection of the power supply.
