Title: Improvements relating to electrical switches with means for extinguishing the arc bygas under pressure
IPC: H01H33/00
Filed: 1930-06-04
Abstract: 356,221. Hightension switches. RUPPEL, S., 8, Palmengartenstrasse, Frankfort . on - Main, Germany. June 4, 1930, No. 17334. Convention date, June 3, 1929. [Class 38 (v).] In switches with the arc disrupted by a blast of air and with two breaks per phase or pole, the separate breaks are arranged in separate casings oppositely directed but in line, or disposed at an angle to one another. In.the form shown in Fig. 1 two insulating casings 9, 10 are mounted in line and supported by a member 8 carried by the insulator 11 on the air supply chamber 13. The casings 9, 10 carry the fixed contacts 1 into and out of which the telescoping contacts 2 move under pneumatic action. The movable contacts are supported within the insulating cylinder 4 carried by the air-supply tube 12, and are provided with pistons 3. When air pressure is supplied to the inside of the tube 12 the contacts 2 are forced apart into engagement with the fixed contacts ; when the pressure is supplied to the space between the tube 12 and the insulator 11 the contacts are forced away from the fixed contacts and the arc extinguished by the escaping air blast. In an alternative construction the insulators 9, 10 are inclined to one another in V-form, the contact-members being operated independently. In the modified construction shown in Fig. 3 the switch is operated by manual or other operation of the shaft 30 which causes movement of the actuating link 28 within the supporting insulator 11. The link 28 is connected through further links 24, 23 to a link 22 jointed to the rectilinearly moving contactmember 2. This construction is duplicated for the two breaks which are disposed in the insulators 9, 10 inclined to one another and both are operated, together, by the mechanism described which for a small movement of the operating shaft gives a large movement of the contact rods. The air blast is supplied through the pipes 17, 18.

IPC: H05H3/06
Filed: 1953-06-23
Abstract: 734,551. Discharge apparatus; producing neutrons. SCHLUMBERGER WELL SURVEYING CORPORATION. June 23, 1953 [July 2, 1952], No. 17413/53. Classes 39 (1) and 39 (4). A discharge tube for producing nuclear reactions comprises a hollow anode 12 containing ionizable gas which leaks slowly through the anode, a surrounding cathode 11 between which and the anode a high-voltage difference is established, and a substance on the cathode in which the nuclear reactions occur under bombardment by positive ions. The ionizable gas may be deuterium or tritium and the anode is of palladium or platinum. The anode is heated by an interior coil 14. The cathode 11 may be of nickel, tantalum, tungsten, zirconium or uranium. The substance on the cathode may consist of a deposit or plating of zirconium or tantalum containing deuterium or tritium. Under the high-voltage difference, electrons released by field emission from the cathode bombard the gas issuing from the anode, for example producing deuterons from deuterium. The deuterons travel to the cathode and bombard for example .tritium contained in the substance on the cathode to produce neutrons. The cathode if constructed of zirconium or uranium will additionally function as a getter for absorbing such deuterium as is not ionized. An additional getter apparatus such as a corrugated zirconium or uranium cylinder 17 heated by a coil 18 may be contained within the discharge tube. Preferably the gas pressure in the tube is maintained in the range of 10<SP>-4</SP> to 10<SP>-6</SP> millimetres of mercury. An axial magnetic field may be provided. In another embodiment the anode is coated with a beta-particle emitting substance. It is stated that the beta particles establish the required high-voltage difference, and an external voltage source is not required. The tube may be used in neutron well-logging methods such as described in Specification 724,441.

Filed: 1961-05-15
Abstract: 1345137 Explosive charges NITROCHEMIE GmbH 15 May 1961 [14 May 1960] 17689/61 Heading F3A A controlled and intensified explosive effect is obtained by combining a primary hollow charge 1 with a secondary ring-shaped charge 2 detonating the secondary charge 2 at least 5 microseconds after the hollow charge 1 has been detonated, and directing the blast from the charge 2 through a cone 3 on to that region of the target 4 which receives the blast from the preceding detonation of the hollow charge 1. The secondary charge 2 may be shielded from the hollow charge 1 by a steel cover 5 having a cone-shaped aperture and be provided with a tubular iron liner 6. The hollow charge 1 may be enclosed within a steel shell 8 and have a cone-shaped recess lined with copper. The transmission of the detonation from the hollow charge 1 to the secondary charge 2 in the embodiment shown is effected by four equispaced fuse cords 9 carrying detonators at their ends. Alternative methods of consecutively firing the charges 1, 2 include the use of electrical high-speed delayed action fuses, interposed priming caps, bodies propelled by the primary detonation, and a detonating membrane. The invention finds application in the perforating of rock overlying petroiferous strata as well as for military purposes, e.g. in projectiles or rockets.

Filed: 1974-04-23
Abstract: 1428314 Rotary IC engines H G ABBEY 23 April 1974 17792/74 Heading F1F A rotary internal combustion engine comprises a rotor 10 fixed eccentrically to a shaft 12 coaxial with the circular cavity defined by stator 11, the cavity being divided into working chambers A, B, C, D by radially slidable plates P 1 , P 2 , P 3 , P 4  mounted in stator 11 and urged inwardly into continuous seating contact with the rotor 10 by springs 63 and pneumatic piston and cylinder devices 60, 62, each slide plate P 1 , P 2 , P 3 , P 4  having at its axially opposite ends radially inwardly extending legs F a , Fb which are guided in radial slots in the stator end-plates, and the zenith Z of the rotor 10 being spaced from the stator cavity wall so that as it sweeps through each working chamber it divides the same into two portions either side of the zenith and inter-connected via the space between zenith Z and the cavity wall. The rotor 10 has a peripheral collar 10A rotatably mounted thereon, sliding between the rotor collar and the slide plates being minimized due to the inward pressure of the plates. Each slide plate, Fig. 4, has ring seals 42a, 42b around legs F a , F b  and urged outwardly by O-rings 41a, 41b, and inwardly biased seal plugs 39a, 39b which are recessed to receive respective ends of a sealing bar 38 which sealingly engages the surface of rotor 10. The main body of the plate has sealing rings 43, 44, the inner one of these sealingly engaging stepped portions of radially extending sealing bars 48a, 48b, in the axial end-faces of the plate. Each working chamber is provided with a respective combustion cavity Ca, Cr, C c , Cd, each having respective intake and exhaust valves and ignition means such as shown at 13, 14, 17 for cavity Ca. In operation, Fig. 19, a previously compressed charge is about to be ignited in chamber A, combustion products are being exhausted through valve 22 from chamber B, compression of previously inducted charge is starting in chamber C, and chamber D is taking in charge through inlet valve 30. In Fig. 20, power stroke is occurring in A, exhaust is completed in B, compression is continued in C, and induction is just finishing in D. Fig. 21 shows end of power stroke in A, induction in B, ignition in C, compression in D and Fig. 22 shows exhaust in A, end of induction in B, power stroke in C and ignition in D. During the next revolution of rotor 10 the chamber B undergoes ignition in phase II, Fig. 20. Thus it can be seen that each cycle takes two revolutions of rotor 10. In an alternative embodiment Figs. 23 to 28 (not shown) a two-stroke cycle is shown wherein the four working chambers are divided into two pairs of chambers, each pair being inter-connected by a transfer duct so that induction and compression occurs in one chamber of the pair and combustion and exhaust in the other. The compression ratio may be charged by altering the position of the slide plates.

Abstract: 876,262. Temperature alarms and measurement. SOC. BELGE DE L'AZOTE ET DES PRODUITS CHIMIQUES DU MARLY. May 1, 1959 [June 5, 1958], No. 18016/58. Classes 40 (1) and 118.  Pre-ignition in furnaces for the pyrolysis of hydrocarbons is detected by means of one or more series of thermocouples associated with the gas passages in the distributer of the furnace, each series having an even number of thermocouples connected in opposition so that the electrical output is zero unless a temperature rise occurs in one passage. Such an arrangement is particularly suitable for use with a distributer as in Specifications 824,328 and 876,261. Fig. 2 is an end view of the distributer (side view in Fig. 1, not shown) in which the solid and dotted lines indicate respectively the two metals of which the thermocouples are made, these being situated in ducts 11 transverse to the ducts 5 carrying the reactants (hydrocarbon and oxygen). There is an even number of junctions and all are connected in series so that a reading on the meter 14 will indicate that the temperature in one passage is greater than the average. This signal can also be used to shut off the reactants and introduce nitrogen instead. To allow for preignition in two adjacent tubes simultaneously (which would not be shown in the arrangement of Fig. 2) two separate series of thermocouples can be provided (Fig. 5), each with its own indicator. In another modification (Fig. 6) the transverse ducts 16 do not extend right across the distributer and are only half as numerous so that each thermojunction is associated with four of the passages 5. The junctions are all connected in series as before, and two additional junctions 18 in the middle pair of ducts are provided to detect any irregular heating in the whole of the distributer. The transverse ducts containing the thermojunctions are preferably located about a quarter of the way up from the bottom of the distributer, and serve also to conduct further oxygen to stabilize the individual flames at the outlets of the passages 5. Specification 839,430 also is referred to.
