Title: Improvements in radio direction finding methods and apparatus
IPC: G01S1/02
Filed: 1937-08-16
Abstract: 502,408. Directive wireless systems; modulating systems. BRONZAVIA SOC. ANON. Aug. 16, 1937, No. 22519. Convention date, Aug. 19, 1936. [Class 40 (v)] In a direction-finding system in which the pick-ups of fixed directional aerials angularlydisposed relatively to one another are modulated at low frequencies which are displaced in phase by an amount corresponding to the angular displacement of the aerials, the modulation is effected by mechanically-variable condensers arranged in the aerial circuits, the variation of the condensers in each circuit being such as to maintain the circuit constantly tuned. In the Figure, the pick-ups from two mutually - -perpendicular frame aerials are coupled to the circuits 1<1>, 1<2> respectively, where they are modulated by means of the continuallyvariable rotary-plate condensers C1, C2 and C3 at the same low frequency but with a phase displacement of 90‹, the modulated signals being obtained across the points a, d. If all the rotary plates are mounted on the same shaft, the phase displacement may be obtained by mounting the two sets of plates at 90‹ to each other about the shaft. In order to maintain the circuits 11, 1<2> constantly tuned to the signal frequency, .the resultant capacity across b, c must be constant and the Specification includes a mathematical discussion of suitable conditions for obtaining this result. The modulation frequency is a function of the shape and the rate of rotation of the condensers, and a method of deriving suitable shapes is given, such shapes being illustrated in Figs. 3-5 (not shown). The two modulated signals are fed through decoupling resistances 4 to the valve 2, where they are combined, and an indication of the direction is obtained by observing the phase of the resultant low frequency, e.g. by comparing it with the phase of one of the modulating frequencies, in a radio-goniometer or suitable phasemeter 3, e.g. a cathode-ray oscillograph.

Filed: 1958-07-15
Abstract: 921,599. Adjusting radio tuning; radio receiver control arrangements. BUSH RADIO Ltd. Aug. 5, 1959 [July 15, 1958], No. 22617/58. Class 40 (5). A tuning mechanism comprises actuating members, each individual to each required operating frequency, which operate a switch to connect one of a number of circuits and also to adjust the circuit connected to the required frequency. A television tuner includes two tubes mounted within a housing 1, the inductors for tuning the receiver to one pair of frequencies being mounted along one tube, and those for a second pair mounted along the other. A core unit comprising alternate cylinders of a ferrite and brass moulded together in a plastic material is mounted within each tube and is biased with a spring to engage a face-plate 3. Mounted between the units is a switch 2 which connects either one or other of the core units into the receiver circuit. The actuators 12 associated with each required frequency are arranged such that when depressed they move the switch 2 to connect the appropriate unit into circuit and at the same time tune the unit by positioning the core inside the unit. The cores are moved by engagement with abutments 11 which fit into slots in the projections 5 and which are carried on half-nuts engaging with a screw-threaded end portion of the actuator. A rocker arm carrying two rods 28, 29 is connected to the switch and is mounted in the frame such that the movement of the actuator causes a projection 27 to engage with one or other of the rods to move the switch into one or other of its positions. A spring- loaded U-shaped latch-plate 33 having a threepoint engagement with the frame and through which the actuators project is provided so that when one of the actuators is depressed, it locks into the operated position and at the same time releases any previously-operated rod. In order to correctly position a core inside its coil, the abutments may be moved along the screwthreaded portion 13 by rotating the actuator rod. Push-buttons may be mounted on the actuator rods by means of flat strips which lie parallel to the rods and which have a bent-over portion at one end shaped to receive the ears 38 at the end of the push-rods. In the normal position this bent-over portion rests against a shoulder 39, but to adjust the position of an actuator along its push-rod, the push-button is pulled out until the bent portion engages with the ears 38 so that rotation of the button rotates the rod. The buttons may be rectangular in cross-section and may be normally prevented from rotation by an escutcheon plate. Alternative forms of pushbuttons are described including round ones having screw-driver slots and rectangular ones having holes through which a screw-drive can project to rotate the rod.

Title: Improved petroleum-refining process and products thereof
IPC: C08K5/09
Filed: 1951-09-28
Abstract: <PICT:0710714/III/1> Crude petroleum is fractionated to give a gas and gasoline fraction, a light gas oil fraction, a heavy gas oil fraction and a residuum fraction, each fraction boiling above the gasoline range is cracked to yield more gasoline and a heavier fraction, including a heavy fuel oil from the cracked residuum fraction and an aromatic cycle gas oil from the cracked heavy gas oil fraction, and the heavy fuel oil is blended with the aromatic cycle gas oil to produce a fuel oil of reduced viscosity.  In this way, a maximum yield of gasoline is obtained from the crude petroleum, while the fuel oil blend is one with little tendency to form sediment. Cracking may be carried out non-catalytically or a catalyst such as silica-alumina or clay may be employed, using fixed bed, moving bed or fluidized catalyst techniques.  In the drawing, crude petroleum passes through preheater furnace 3 to atmospheric still 1 and the bottoms from this still are passed through reheater 4 to vacuum still 2.  Light gas oil from still 1 and heavy gas oil from still 2 pass to catalytic cracking units 101 and 10 respectively.  These cracking units employ fluidized catalyst and are provided with catalyst regenerators 111 and 11 and distillation towers 121 and 12.  The residuum from still 2 passes to visbreaker coil 30 and the visbroken product is fractionated in separation tower 32.  Heavy fuel oil bottoms flowing from tower 32 meet and blend with aromatic cycle gas oil flowing from tower 12.  Specification 700,137 is referred to.

Abstract: 698,809. Vapour burners. PARR, K. Sept. 19, 1950 [Sept. 21, 1949], No. 22969/50. Class 75(i) A vapour burner is provided with a device for silencing the combustion, comprising two superposed saucer-shaped members spaced apart to provide a gas spreading passageway into which the fuelair mixture enters through a hole in the lower member, and which is adapted to prevent the ignition of the mixture therein, the upper member being protected by heat insulation from radiation of heat from the burner flame. A vaporizing tube, Fig. 1, upstands from a tray 2 in which a light fuel oil is burnt for preheating the liquid fuel, e.g. paraffin oil supplied under pressure to the tube 3, and vapour thus generated issues from a jet 5 above which is supported by pillars 7 the burner head 6. The latter comprises a pair of spaced superposed saucers 11, 13, Fig. 2, the lower saucer 11 having an aperture 12 for receiving a mixture of fuel vapour and induced air which passes through the passage 24 between the saucers to..an annular burner mouth where it is ignited, the spreading of the fuel-air mixture in the passage 24 ensuring steady, quiet combustion. The saucer 13 is supported on the saucer 11 by means of pins 14 which have extensions 16 engaging holes in the saucer 11 and are of elongated crosssection, to minimize opposition to the flow of the combustible mixture. In order to provide an even flame around the whole periphery of the burner mouth the parts 27 of the mouth where the flow is affected by the pins 14 are narrower than the remaining parts 28. In addition, a restric tion 26 provided in the passage 24 assists in rendering the flow even, the passage 24 being tapered outwardly from the restriction 26 to the parts 28 of the mouth. During operation of the burner the upper end 25 of the vaporizing tube is heated by the burner flame. The saucer 13 is protected from heat radiation from the flame by a layer of asbestos 19 supported therewithin by a metal disc 18 and a central pillar 23 from which extends. a screw 22 serving as a handle for removing the saucer 13.
