Title: Wave-signal transmitting and receiving system of the radar type
IPC: G01S13/18
Filed: 1945-01-29
Abstract: 590,711. Radio signalling. HAZELTINE CORPORATION. Jan. 29, 1945, No. 2307. Convention date, Feb. 19, 1944. [Class 40 (v)] In a transmitter-receiver system for transmitting pulse signals to a distant point within a given operating distance and receiving back related pulse signals, the receiver is rendered sensitive for an interval following each transmitted pulse not substantially longer than the propagation time to and from the distant point. This mode of operation results in the reduction of noise interference and of interfering radiation if a super-regenerative receiver is employed and enables the receiver to be operated at a higher sensitivity than is possible with continuous operation. The pulse transmitting and receiving system shown, which may be employed to interrogate a responding beacon, comprises the power oscillator 12, pulse modulated by the keying unit 10 and amplifier 11, and the receiver comprising R.F. amplifier 17, super-regenerative stage consisting of valve 19, quench oscillator 29 and diode detector 31, and the modulation signal amplifier 35 and reproducer36. Valve 19 and the diode 31 are normally biassed - off by means of resistors 55 and 50 which are common to the normally conducting valves 48, 47. The gain of the pentode 18 in the R.F. amplifier is also reduced by virtue of the voltage drop in resistor 57. The positive modulating pulses, curve A, from the amplifier 11 are fed to cause valve 40, which is normally biassed-off, to conduct and discharge condenser 43 rapidly. At the end of the pulse, condenser 43 commences to charge up through the variable resistor 45. The waveform B produced at the anode of valve 40 is fed through condenser 49 to the grids of valves 47, 48 which are thereby put off so that the cathode potentials of valves 19 and 31 vary as indicated at C, while the screen voltage of valve 18 varies as indicated at D and raises its transconductance above the average value for steady state operation. The duration t0-t1 of the receptive period is thus controlled by adjustment of the variable resistance 45.

Title: Self-induced magnetic field controlled gas shielded-arc welding process and apparatus
IPC: F27D99/00
Filed: 1952-01-29
Abstract: 699,944. Welding by fusion. UNION CARBIDE & CARBON CORPORATION. Jan. 29, 1952 [March 7, 1951], No. 2417/52. Class 83 (iv). [Also in Group XI] A method of electric welding in which an arc is shielded by a stream of protective gas is characterized by providing a discontinuous path of high permeability for the electromagnetic field surrounding the electrode in the vicinity of the arc, thereby distorting the symmetry of such field and causing the arc to be directed at an inclined angle toward the work-piece and advancing the electrode along the work-piece in the direction in which the arc is inclined. A gas-shielded arc welding torch 10 is positioned over a work-piece 12, to provide an are 14, under an electrode 16. The torch comprises a tubular body 17, and a nozzle 18, annularly spaced from the electrode 16, to provide a passage 21, for a shielding gas stream, e.g. helium or argon, which flows from the interior of the body 17. The electrode may be of tungsten or a consumable metal similar to that of the work metal. The nozzle is composed of non- magnetic material, such as copper, and has a cylindrical end portion 22, provided with a splitring 26, of soft iron or steel having a gap filled with non-magnetic material 28. The ring may be of soft iron or steel or a permanent magnet or of cobalt, iron-nickel and iron-silicon alloys. In operation, when the arc is struck, the splitring is magnetized by the flux surrounding the electrode and due to the sudden change in permeability at the gap the magnetic field in the vicinity of the arc is sufficiently disturbed to direct the arc forwardly as the torch 10 is moved rapidly along the welding path. An oval-shaped nozzle 30, with a similarly-shaped split ring 32, may be used for butt-welding 16-gauge stainless steel at a speed of 75 inches per minute with a welding current of 350 amperes and a flow of argon gas of 15 cubic feet per hour. For reducing the magnetic field in order to avoid excessive arc displacement a soft iron keeper 38 (Fig. 6) is used. Adjustment of the keeper along the stem of the nozzle 34 changes the strength of the horizontal component of the magnetic field at the welding zone to the desired value.

Title: Improvements relating to carburetting water gas with heavy oil
Inventor: HAWES JACK MALCOLM
IPC: C10J1/213
Filed: 1952-02-01
Abstract: 713,976. Carburetting water gas. HUMPHREYS & GLASGOW, Ltd. Dec. 31, 1952 [Feb. 1, 1952; Aug. 13, 1952], Nos. 2762/52 and 20369/52. Classes 55 (I) and 55 (2) In a cyclic process for carburetting water gas with heavy oil, carbon residues are deposited during the gas-making period in a bank of checkerbrick and are subsequently burned off with air which has been highly heated by passing through another checkbrick bank, both banks being heated by blow gas during the blow period. The apparatus consists of a generator a, a carburetter b and a superheater c. In Fig. 1, the carburetter contains two checkbrick banks 1 and 2 separated by a space 5 into which heavy oil can be sprayed through a nozzle 6. The cycle consists of a gas making period during which the injected oil is cracked in space 5, the carbon formed being retained in bank 2. The run is followed by a blow during which both banks are heated by a blow gas and then a carbon-burning period during which air is admitted to the top of the carburetter through a connection 3X, is highly heated in bank 1 and burns off the carbon in bank 2. To dispense with the separate carbonburning period, the carburetter may have three checkerbrick banks 1, 2 and 7, Fig. 2, the pipe 3 from the generator entering the space between banks 2 and 7 whilst oil can be sprayed into the space between banks 1 and 2 from nozzle 6. In this case the blow is carried out in two stages. In the first stage, blow gases pass up through banks 2 and 1 and discharge through a stack 9. In the second stage, the gases pass downwardly through bank 7 to the superheater whilst air is admitted at 10, is heated in bank 1 and burns carbon deposited in bank 2 during the previous gas-making period. During the run, oil is sprayed into space 5 and a small quantity of steam is admitted at 11, carrying the oil gas downwards to mix with the flue gas entering the carburetter from pipe 3.

Title: Improvements relating to fluid pressure braking apparatus

Filed: 1925-02-04
Abstract: 241,507. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Dean, W. E.). Oct. 15, 1924, [Convention date]. Fluid-pressure. - In fluid-pressure brakes means are provided for temporarily cutting off the train pipe from the auxiliary reservoir upon a predetermined increase in train pipe pressure, whereby a more nearly simultaneous release of the brakes throughout a train may be obtained. The invention is shown applied to a triple valve of the retarded release type comprising a piston 3, main and graduating valve 5, 6, a spring stop 14, and an emergency vent valve 9. A supplemental reservoir 16 is provided, which is connected through a non-raturn valve 30, constricted passage 29, and passage 17 to ports 18, 19 opening into the piston chamber 2, and through a restricted passage 28 to a passage 20 which registers, both in the full and retarded release positions of the slide valve 5, with the valve passage 21 leading to the valve chamber 4 and auxiliary reservoir 8. During both service and emergency brake applications, the triple valve functions as usual, but on increasing the train pipe pressure to release the brakes, the triple valves at the head of the train, where the rise in pressure is most rapid, overcome the action of the spring stop 14 and move fully to the right, so that the ports 19 leading to the auxiliary reservoirs are closed, the latter being, however, supplied from the reservoirs 16 by the passages 20, 21. The auxiliary reservoirs being out off from the train pipe, the increase in train pipe pressure will be propagated rapidly down the train, and when the pressure in the chamber, assisted by the stop 14, is sufficient to move the piston 3 back to the full release position shown, the charging of the auxiliary reservoirs will be completed through the ports 18, 19, whilst, when train pipe pressure exceeds the depleted pressure in the supplemental reservoirs, the latter will be recharged past the constriction 29 and non-return valve 30. The constriction 28 prevents the premature return of the piston 3 to full release position.
