Abstract: 435,712. Stabilizing fins for flying- boats. SAUNDERS-ROE, Ltd., KNOWLER, H., and FARROW, J. R., Medina Road, East Cowes, Isle of Wight. April 21, 1934, No. 12056. [Classes 4 and 113 (ii)] The lateral stabilizing fins of flying-boats are backward swept at an angle exceeding 15‹ to the perpendicular to the line of flight into a position in which their leading edges lie approximately parallel to the line of the wave which is thrown outwardly and backwardly on both sides of the bow of the hull when moving through water. The amount of sweep back for any given hull may be determined by towed model tests. Several forms of float are described, all of streamline section so set as to have little or no positive angle of incidence in flight at cruising speed. Fig. 1 shews a hull having fins b, b<1> of which the trailing edges are parallel to the swept back leading edges. In a modification, Fig. 3, the trailing edges c<3> are normal to the direction of flight but are cut away at c<4> to reduce the resistance set up by the spray thrown up from the main step. According to further modifications the fins may have rounded corners in plan view and their tips rounded as shown in Fig. 6, and may form a continuation of the transverse section of the hull bottom. The fins are located either amidships or somewhat forward of amidships.

Abstract: 1393212 SCR control circuits ELECTRICITE DE FRANCE 14 March 1973 [28 June 1972] 12218/73 Heading H3T [Also in Division G3] In a temperature control for an A.C. energized heater 3 a triac 4 is fired substantially at zero voltage crossovers of the A.C. supply by a circuit comprising an N.T.C. thermistor sensor Th27 connected as shown to a UJ transistor Q26, a desired temp. resistor 25 and supplied by rectified D.C. from a source 10. In operation, during negative half-cycles of the A.C. supply a transistor Q21 produces a square wave signal the level of which depends upon the setting of the desired temp. resistor 25. This signal is applied between the base B 1  and emitter of Q26. The voltage between the bases B 1  and B 2  varies in proportion to the resistance variations of Th27 and thus to the sensed temperature. The peak point voltage of Q26 varies in the same direction as the B 2 -B 1  voltage and will thus depend on the value of Th27, varying inversely therewith, i.e. the peak voltage increases as the sensed temp. increases. When the square wave signal level is greater than the peak point voltage of Q26, the latter fires and sends the square wave signal to the terminals of R28. An amplifier Q29 amplifies the signal producing an output in phase opposition thereto and in phase with the A.C. supply voltage. A capacitor C32 produces a positive pulse from the leading positive-going edge of the square wave and a negative firing pulse from the trailing edge to fire the triac as the A.C. voltage is passing through zero.

Title: Improvements in or relating to the desulphurisation of hydrocarbon oils
Inventor: WEBSTER ALFRED BENTLEY
IPC: C10G27/12
Filed: 1961-04-06
Abstract: The sulphur content of hydrocarbon oils, at least 50 vol. % boiling above 250 DEG  C., is reduced by treating the oil with an organic peracid, or a mixture of organic acids and hydrogen peroxide such as to give rise to the formation of a peracid, to yield products containing both oxygen and sulphur, and subjecting the thus treated oil to a thermal after-treatment, preferably above 350 DEG  C., which decomposes at least a proportion of said products to give hydrocarbons and volatile sulphur compounds.  The hydrocarbon oil may be treated dissolved in a low-boiling organic solvent, for example benzene or carbon tetrachloride. Preferred oxidants are mixtures of hydrogen peroxide with formic or acetic acid. The thermal treatment may be effected in the presence of an alkaline material such as dolomite or lime.

Abstract: 615,516. Cathode-ray oscillographs. SPERRY GYROSCOPE CO., Inc. June 29, 1944, No. 12435. Convention date, June 22, 1943. [Class 37] [Also in Group XL (c)] In a means for producing timing markers for an intensity-modulated cathode-ray tube, the output from a pulse generator is applied to a first control grid of the cathode-ray tube to produce bright timing markers in the absence of received signals and the output from the pulse generator is also applied through an inverter to a second control grid, the inverter being rendered operative in the presence of received signals, so that its output suppresses the cathode-ray beam to produce dark timing markers which contrast with the bright signal indication. The invention is described as applied to a pulse radar system in which the responses are displayed by intensity modulation on a cathode-ray tube 38, Fig. 2, in which the horizontal deflection is proportional to azimuth and the vertical deflection is proportional to range (i.e. B scan). Bright range marker lines 104 are produced by applying positive marker pulses to the control grid of the cathode-ray tube, but these markers are not distinguishable in the presence of large responses such as 92A and 92D and according to the invention the marker pulses are inverted during periods of echo reception and applied to a second grid to bias the tube off and produce dark range lines 113 and 114 through the bright responses. In Fig. 1, the aerial reflector 14 is mechanically scanned in azimuth, and echoes from the video output stage 12 of the transmitter-receiver 11 are fed through the cathode follower 26 and limiter 27 to the control grid 41 of the cathoderay tube 38 which is scanned by currents through the horizontal and vertical deflecting coils 21 and 20 synchronized with the aerial scanning motor 17. The tube is rendered unresponsive to the direct transmitter pulse by a gate pulse fed through the conductor 47 to the cathode 39 and the bright range markers 104, are produced by feeding positive marker pulses from the synchronized calibrator generator 24 to the control grid 41 through the cathode follower 34 and limiter 27. The calibrator pulses are also fed to the grid of the triode 36, the cathode impedance of which is constituted by the negatively biassed triode 37 to the grid of which the positive video signals are applied after D.C. restoration by the rectifier 75. In the absence of echo signals, the valve 37 is non-conductive and the calibrator pulses are not transmitted by valve 36, but during periods of reception of echo pulses, valve 37 is conductive and the calibrator pulses appear as negative pulses in the anode circuit of valve 36 and are applied to the normally positive second control or screen grid 42 of the cathode-ray tube to bias the tube off and produce the dark range lines 113, 114, Fig. 2.
