Title: Improvements in or relating to electric measuring instruments
IPC: G01R5/14
Filed: 1943-07-03
Abstract: 565,201. Electromagnetic ammeters and voltmeters. SANGAMO WESTON, Ltd., and LOVEGROVE, H. J. July 3, 1943, No..10818. [Class 37] In a moving iron instrument of the radial vane type the movable vane is mounted on a pivot eccentric to the axis of the exciting coil and moves between two positions both close to the inner wall of the coil, the fixed vane being near to and parallel with the radial face of the movable vane in one limiting position while as the movable vane approaches the other limiting position the strength of magnetization of the vane increases. A spindle 2 carrying a pointer 3 is arranged to pivot about an axis which is eccentric with. respect to the axis of the coil 1. The pointer 3 moves between stops 5, 6 and in the absence of current through the coil 1 is held in the zero position by a controlling spring. The fixed vane 7 is secured to the inner wall of the coil 1, and the movable vane 8 is secured to the spindle 2. When current flows in the coil, like poles are generated at adjacent ends of the vanes, causing repulsion between them. The magnetization of the vanes is strongest at the edges of the vanes nearest the inner wall of the coil and decreases during the initial movement owing to the increasing distance between the vane and the inner surface of the coil. The magnetization reaches a minimum in the central position of the movable vane and then increases for the remainder of its movement. The result is that the scale readings at the top and bottom ends of the scale are opened up with respect to those at the centre and the scale may be made substantially linear from 10 degrees upwards.

Title: Process for the catalytic treatment of hydrocarbons
IPC: C01B3/22
Filed: 1958-04-08
Abstract: 880,355. Making town's gas by catalytic treatment of hydrocarbons. OTTO & COMPANY G.m.b.H., C. April 8, 1958 [April 11, 1957], No. 10976/58. Class 55 (2). Hydrocarbons having six and more carbon atoms are heated for a short time, e.g. 1 second at a temperature in the range 400-600‹ C. in the presence of steam but with little or no free oxygen present so as to effect considerable transformation of the hydrocarbons into those having a lower number of carbon atoms per molecule than had the untreated hydrocarbons and subsequently these treated hydrocarbons are passed into a catalyst-containing reaction chamber together with a gas containing free oxygen. Carburetting agents may be introduced into a hot gaseous stream leaving the reaction chamber whereby the colorific value of the final gaseous product in the stream is increased. Thermal cracking of the carburetting agents is thereby achieved which results not in the production of carbon monoxide and hydrogen but in the formation of lower olefines, e.g. ethylene and propylene. Examples are given.

Title: Automatically protected pitot static tubes
IPC: G01P5/165
Filed: 1938-04-11
Abstract: 502,060. Heating Pitot-tube apparatus electrically. KOLLSMAN, P. April 11, 1938, Nos. 11016 and 11017. Convention dates, April 9, 1937 and March 12, 1938. [Class 69 (i)] [Also in Groups XI, XXXV, and XXXVII] An electric heater B, Fig. 1, arranged to heat conductively the metallic dynamic and static pressure conduits 2, 5 of the Pitot head of'an aircraft speed-indicator in order to keep them free from ice &c. is protected from overheating by automatic means controlling the current supply to it in dependence upon the rate at which the heat is dissipated. In the form shown in Fig. 1, the Pitot tube consists of a dynamic pressure tube 2 extending within an outer shell A forming the static pressure conduit 5 and provided with static pressure openings 4. A tube 7 extends from the conduit 2 to drain any moisture which' may enter.the latter. The heater B consists of enamel-embedded wire enclosed in a copper shell which is preferably welded or soldered to the shell A. The current supply to the heater passes through contacts 17, 18 of a switch mounted on a partition 20 and comprising a bimetallic strip 19 which causes the' contacts to open at a predetermined safe high temperature. In a modification, the switch controls a relay which operates a switch in the heater circuit. In a further modification, the switch is located at a point outside the Pitot tube, and controls the heater current in accordance with the temperature of the ambient air. In another form, the current is limited by including in the circuit a resistance having a high temperature coefficient, for which purpose the heater element may be formed of nickel wire. In place of, or in addition to, the use of a temperature-responsive switch, the heater circuit may be controlled by a member responsive to the air-pressure when the aircraft is in flight, the circuit being completed only at such times. In the arrangement shown in Fig. 14, the circuit of the heater 108 is controlled by a relay 115, the energizing circuit of which is controlled both by a temperature-actuated switch 121 and by contacts 128 controlled by a pressure-actuated capsule 127 connected to the dynamic pressure duct of the Pitot tube. The heater is thus in operation only when the machine is in flight and the temperature is below a predetermined maximum.

Title: Improvements in or relating to radar systems
IPC: G01S7/34
Filed: 1945-05-02
Abstract: 599,389. Radiolocation. ROBSON, J. M. May 2, 1945, No. 11196. [Class 40 (v)] In a radar system of the kind described in Specification 598,649, wherein the main reception lobe of the directional receiver performs a continuous conical scan and traverses four predetermined positions in its orbit coincidently with the transmission of exploring pulses so that the relative amplitudes of pairs of echo signals received in opposite sectors are indicative of misalignment of the axis of the cone with the reflecting body, automatic gain control is provided to maintain the mean amplitudes of both pairs of echo signals equal. Switching waves as shown in Fig. 2 (b) are applied to the circuit of Fig. 1 at points 44, 45, 46, one wave being in phase quadrature with the other so that after full wave rectification in valves V7 and V8, Fig. 2 (c), and shaping in the clipper amplifiers V15, V16, square waves as shown in Figs. 2 (e) and 2 (f) are obtained and are applied as switching waves to the screen grids of the valves V12, V13. Thecorresponding positions of the reception lobe during these switching waves is indicated in Fig. 2 (a). Four D.C. voltages representative of the signal intensities at the four positions of the reception lobe are obtained in separate channels and are applied to the four input terminals 71, 72, 73, 74 and are so arranged that the voltages corresponding to opposite paris of lobe positions are combined and applied to the two cathodes of double diode V11. The potentiometers P1, P2 are used for threshold control. Thus signals corresponding to the mean signal received from both pairs of sectors are applied to the grids of valves V12 and V13, which have a common cathode circuit from which the A.G.C. voltage is taken at point 82. The valves V12, V13 are cut-off alternately by the waves 2 (e) and 2 (f) so that the cathode potential follows that of the grid of whichever valve happens to be conducting and thus it is arranged that a voltage proportional to the mean signal obtained in a certain pair of sectors is obtained from the point 82 when the reception lobe is in one of the sectors of that pair. This voltage, shown at Fig. 2 (g) is taken as an A.G.C. voltage for the control of the I.F. amplifier of the radar receiver.

Abstract: 1375205 Display apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Jan 1972 [26 April 1971] 11369/71 Heading G4H In order to position a selected slide in a display apparatus 1, Figs. 1, 2 (not shown) a motor 10 positions a slide magazine so that the required slide may then be extracted by means of a motor 16. A 5-bit binary input 31 (from punched tape or card, or from a telephone dial) representing the desired position of the magazine is fed to a comparator 36 together with a binary coded representation of the instantaneous position of the magazine derived from an optical shaft encoder 11, motor 10 being operated until their difference is zero; motor 16 is then actuated to raise the slide to one of two positions between a translucent screen and two groups of fluorescent lamps, the position of the slide depending on whether one slide alone or two slides one above the other are to be displayed, and the output from a shaft encoder 17 controls the illumination accordingly. If required a second slide is then selected and moved into position below the first slide. When the display is terminated, the above procedure is reversed, a photocell serving to detect jamming of a slide. The input is admitted to buffers 32 or 33 (if 32 occupied) and fed to 36 via fast bi-stable selection switches 30, 37 and a latch 34 (all controlled by a logic circuit 40) and via a memory 35 containing a biased reed switch for use in the event of a power supply interruption. The difference from 36 may be used to control both the direction of rotation and the speed of motor 10. The output from encoder 11 is monophylic and is decoded (12) for comparison with input 31; the encoders may alternatively be vane switched detectors or magnetically operated reed switches.
