Title: Improvements in and relating to lightning arresters
Filed: 1931-08-06
Abstract: 387,696. Protective arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hull, A. W. ; 1435, Lowell Road, Schenectady, New York, U.S.A.) Aug. 6, 1931, No. 22295. Convention date, Aug. 6, 1930. Addition to 344,092. [Class 38 (iv).] A lightning-arrester as claimed in the parent Specification has the envelope formed in part by one of the electrodes 52 and the other electrode is supported by a re-entrant stem 53. A tubular shield 59 covers the joint between the outer electrode and the glass wall 50. A resistance element 54 of material such as is described in Specification 292,110, [Class 38 (iv), Electric supply and transmission systems &c.], which decreases in resistance with increasing current, may be enclosed in the re-entrant stem 53 accompanied by an insulating fluid such as mineral oil. The Specification as open to inspection under Sect. 91 described also an arrangement of arrester tubes according to the parent Specification connected in series and placed within a hollow insulator, the first and last tubes being connected to conducting caps at each end of the insulator, and an arrangement by which the current through an arrester according to the parent Specification generated a magnetic field so arranged with respect to the gap between the electrodes as to exert an interrupting effect upon the current. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to radio apparatus for detecting aircraft
IPC: G01S1/02
Filed: 1937-08-13
Abstract: 500,588. Indicating proximity of aircraft. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and PLAISTOWE, D. L. Aug. 13, 1937, No. 22355. [Class 37] [Also in Group XL] In a radio system for detecting aircraft comprising a television indicator, a short-wave transmitter and a plurality of short-wave receivers distributed over the detection area and connected to the television indicator by transmission lines, the transmitted waves are modulated with impulses of a frequency corelated with the scanning line frequency of the indicator, and the signals from one or more of the receivers are applied as picture signals to the television indicator. The deflection plates 4, 5 of the cathode-ray tube 1 are supplied with a frame frequency of 50 cycles and a line frequency of 10,000 cycles from the time-base circuits 7, 8 which may be driven from the master source 6.- The output from the line - time-base circuit 8 is fed to the network 9 designed to produce short rectilinear synchronising pulses of, line frequency which modulate a short wave transmitter 11 in the modulator 10 such that the modulation impulses are of longer time length than the synchronising impulses. Radiation from the transmitting aerial 12 is picked up by the distributed receivers 13-16 and applied to the control grid of the cathode-ray tube 1 through transmission lines 17-20, switches 22-25, and the mixer stage 21. In the absence of any reflector in the vicinity of the receivers a black bar is seen down one edge of the television " raster " (assuming the framing direction to be vertical) due to the elongated pulses transmitted. If an aircraft is near one of the receivers, that receiver picks up an indirect wave reflected from the aircraft which is out of phase with respect to the direct wave and an additional black bar, which moves with the aircraft, is seen on the " raster." By opening all the switches 22-25 and closing them one at a time the direction of the aircraft can be determined.

Title: Improvements in or relating to motor - fuel
IPC: C10L1/02
Filed: 1946-07-26
Abstract: A motor fuel contains an incompletely dehydrated industrial alcohol together with methyl benzoate or benzoic acid.  The distillation heads of oil of ylang-ylang, which contain methyl benzoate, may be used instead of methyl benzoate itself.  In an example, a motor fuel consists of petrol, industrial ethyl alcohol and methyl benzoate or distillation heads of oil of ylang-ylang.  The Specification as open to inspection under Sect. 91 refers to a motor fuel containing an industrial alcohol and an ester having a simple or complex aromatic or terpenic nucleus in its molecule, particularly methyl benzoate or a substitution derivative thereof, or the corresponding acid.  This subject-matter does not appear in the Specification as accepted.

Title: Fluidized catalytic cracking of a gas oil feed and simul taneous upgrading a gasoline feed
IPC: B01J8/26
Filed: 1974-05-20
Abstract: 1470073 Cracking; reforming naphtha UOP Inc 20 May 1974 [21 May 1973] 22405/74 Heading C5E [Also in Division B1] In a process for cracking a gas oil and simultaneously upgrading a gasoline (a) the gasoline and freshly regenerated catalyst are fed (by lines 3 and 4) to an upstream part (5) of a dilutephase riser reactor (1), (b) the gas oil is fed (by lines 6 and 7) to the reactor at a point (8) downstream of that at which the gasoline and catalyst are fed, (c) used catalyst and product are discharged (at 11) from the reactor, (d) the product is separated from the catalyst (at 12 and 18) and recovered (at 21), (e) the used catalyst is is regenerated under conditions such that the coke on the catalyst and the CO produced are both burned, and at least part of the heat of combustion of the CO is transferred to the catalyst, and (f) the so regenerated catalyst is used in step (a) above. As shown, used catalyst is stripped at 9 and passes by line 24 to a first dense bed 26. Regeneration gas from line 30 is heated if necessary (usually only at startup) at 31 and distributed at 32. Regenerated catalyst is lifted by the regeneration gas through riser 29, where CO is oxidized substantially completely. This may be assisted by regeneration gas supplied by line 50, or fuel for heating by line 48. The catalyst is separated from regeneration gas at 34 and 40, and stripped in a second dense bed 37 before return by the line 4. The reaction conditions in the downstream part of the cracking zone are less severe than in the upstream part, that is lower temperature, lower ratio of catalyst to oil and shorter residence time. The gasoline feed may be a coker naphtha, a visbreaker naphtha, a pyrolysis naphtha, a straight-run gasoline or FCC gasoline. The preferred catalysts are of the zeolite type.

Abstract: 615,141. Electric welding. WILLIAMS, B. H. LEPINE-. July 29, 1946, No. 22480. [Class 83 (iv)] In a fluid-pressure operated, electric flashwelding machine the movement of the head d during flashing is effected by controlling the medium directly by a throttle valve which is byepassed by a further valve to control the upsetting. A double-acting piston k is used to which full line fluid pressure is fed on one side through a control valve l. The flow from the reverse side passes through a throttling valve m during flashing and is freed for upsetting when the throttle m is byepassed by the valve n. The co-operating head b is fixed and the electrodes a, c are connected to the secondary of a primary-tapped transformer. The valves l and n are two-way for head retraction and are hand, electronic or automatically table-controlled.
