IPC: H01H33/16
Filed: 1950-07-28
Abstract: 673,312. Air-blast circuit-breakers. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. July 28, 1950. [Aug. 2, 1949] No. 18880/50. Class 38 (v). A circuit-breaker has two contacts 14, 18 movable about a common pivot 17, the contact 18 separating first from its fixed contact 19 without forming an arc, followed by separation of the contact 14 from a tubular fixed contact 13 to form an arc in parallel with a resistance 24, this arc being extended through a nozzle 9 where it is extinguished by the air-blast, a further arc in series with the resistance being formed when the contact 14 separates from a second tubular, fixed contact 15. The contact 14 then moves to a position 14<SP>1</SP> to form an isolating gap and to give a visible indication that the circuit is open. The contacts are operated by a mechanism 21 which may be a fluid piston and which has a cam 31 acting through levers 29, 30 to open a valve 2, which is reclosed before extinction of the second arc which is blown out by residual pressure in the contact chamber. Contact 13 is mounted in the centre of an electrode 11 carried by a metal collar 6 and having an arcing tip 12 of refractory metal, the nozzle mounting 8 being separated from collar 6 by an insulator 7. In a modification, Fig. 3 (not shown), all of the parts are mounted on a single insulator supported by the air container 1, and in a further arrangement, Fig. 4 (not shown), the contact 15 is on the outlet side of nozzle 9 so that contact 14 passes through the nozzle. The contacts 18, 19 which short-circuit the breaker, may be omitted, and the circuit-breaker may be arranged with all its live parts in front of a partition, Fig. 2 (not shown).

Abstract: 1427802 Aircraft with cycloidal propellers P BASTIDE 19 April 1973 [26 April 1972] 18930/73 Headings B7G and B7W An aircraft, comprising a body 4 of oval shape in longitudinal vertical section and with the principal axes intersecting at a point O positioned above the centre of gravity position G, is provided with four cycloidal propellers 5, 5<SP>1</SP>, 6 and 6<SP>1</SP> which when operated in unison are the sole means providing lift and propulsion and when operated differentially may assist in control. Each propeller comprises a rotatable annular disc 1 on which are mounted a plurality of variable pitch blades 2 selectively adjustable by an eccentric and connecting rod mechanism in known manner. A gas turbine engine 24, having air intake 26 and bifurcated nozzles 27, drives an electric generator 25 which supplies current to an electric motor associated with each propeller. Adjustable surfaces 7, 8 and 18 and 19 are provided for control in roll, yaw and pitch respectively, though alternatively such control may be effected by variable pitch airscrews (Fig. 3, not shown). Other arrangements are described employing only two cycloidal propellers or a number greater than four. A still further embodiment (Figs. 7 and 8, not shown) comprises an all-wing aircraft having a cycloidal propeller at each lateral edge of the wing driven from a gas turbine engine through clutches, gearing and shafting. Instead of a single fuselage as shown in Figs. 1 and 2 there may be two spaced-apart fuselages rigidly connected together with cycloidal propellers mounted on the outboard side of each fuselage and with paddle wheel propellers mounted to bridge the two fuselages. An aircraft as shown in Figs. 1 and 2 may be adapted on its lower surface to be connected to the upper surface of a lighter-than-air cargo-carrying craft which supplies most or all of the lift, the cycloidal propellers of the upper aircraft providing control and propulsion.

The mining machine of a mining installation for operating on an inclined seam has a brake or clamping device that is arranged to so cooperate with a fixed guide rail 5 as to prevent accidental or return movements of the machine along the rail in the direction of the downward gradient of the rail. The device comprises two spring-loaded shoes biassed against and partly surrounding the rail and joined together by a screw threaded pin 15 that extends transversely of the rail, is rotatably mounted in one shoe to have a free, axial movement in said shoe and has a screw connection with the other shoe. The pin 15 is rigidly secured in an arm 25 pivotally connected by a pin 28 to an arm 29 pivoted at 30 on the body of the machine. The linkage of the arms 25, 29 is of such a configuration and is so located on the machine that run back of the machine causes, because of the normal light engagement of the shoes with the guide and rotation of the pin 15 to draw the shoes together to clamp onto the guide rail. The device can be neutralised by an actuator as long as power is supplied to a traction motor of the machine or an appropriate tension is maintained in the haulage cable of the machine. The actuator may be controlled by limit switches associated with tensioning means for the haulage cable or by, in the case of the traction motor, hydraulically actuated solenoid valves. The guide rail may have friction-creating coatings or ridges or recesses.

Abstract: A simple caesium salt is obtained by reacting an insoluble complex cyanide of caesium with an aqueous suspension of a solid reagent to form a precipitate containing all the cations and anions of the complex cyanide except caesium, separating the supernatent liquid, and removing water to leave the caesium salt. The complex salt of radio-active Cs 137 may be precipitated from a nuclear fission product solution by treatment with zinc and ferrocyanide ions according to U.S.A. Specification 2,769,780 and 2,952,640; the compounds precipitated include Cs2ZnFe(CN)6, Cs2ZnFe(CN)6.xZn2Fe(CN)6, CsFeFe(CN)6.xFe4[Fe(CN)6]3 and CsZnFe(CN)6.xZn3[Fe(CN)6]2; complex cyanides in which the metal in the anion is cobalt, nickel, or copper may also be obtained.  The preferred solid reagent is silver carbonate which reacts with the zinc ferrocyanide complex to form insoluble silver ferrocyanide, insoluble zinc and iron carbonates, and a solution of caesium carbonate; preferably the reaction mixture has a pH of 4-9 and a temperature of about 90 DEG C. The caesium carbonate solution is removed and may be evaporated to dryness or treated with hydrochloric acid to form caesium chloride.  According to a prior art method the complex cyanide is dissolved in strong mineral acid and treated with silver nitrate to precipitate silver ferrocyanide, leaving zinc and caesium in solution as nitrates.

Abstract: 406,913. Rectifying alternating current. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. July 10, 1933, No. 19536. Convention date, July 8, 1932. Addition to 397,745. [Classes 35 and 38 (ii).] In an arrangement for imparting a compound voltage characteristic to a grid-regulated rectifier 2 in which the magnetic axis of a synchronous motor 3 driving the grid potential distributer 9 is displaced in dependence on load current as described in the parent Specification, the displacement is effected by utilizing a part of the load current to excite a component of the field of the motor. In the arrangement shown in Fig. 1, the stator windings 3<a> of the motor are energized from an A.C. source 18 synchronous with the rectifier supply network 16, and the parts I, II of the rotor winding are excited from a constant source of D.C. 5. The parts II, III of the rotor winding are excited from a shunt 10 on the D.C. side of the rectifier so that the magnetic axis of the rotor is shifted in accordance with variations in load current thus effecting a phase shift of the grid potentials to effect regulation. In a modification (Fig. 2, not shown) the variable component for the rotor field is derived from a current transformer in the primary circuit of the transformer 1 through an auxiliary rectifier. Chokes adapted to saturate at different current values are provided in the auxiliary rectifier circuit in order to modify the voltage characteristic.
