Title: Double side band-quadrature carrier modulation system
IPC: H04L27/02
Filed: 1972-08-15
Abstract: 1395804 Digital transmission; phase and amplitude modulation CODEX CORP 15 Aug 1972 [14 Sept 1971] 38028/72 Heading H4P A double side band differential PSK quadrature amplitude modulated system employs multiples of bit combinations defined by sets of four equal quadrature vectors each set being mutually concentric, and equi-rotationally displaced from and having differing amplitude to immediately adjacent sets. This permits a smaller amplitude difference than if the vectors were not rotationally displaced for the same signal/noise ratio. A stream of bits at rate n/T is passed into an n bit shift register 10 connected to circuit 12 (given in detail in Fig. 4a, not shown), forming M=2n pairs, output words from which control D/A converters 14, 16 issuing a bi-level output. Once each T seconds the outputs are gated to form a pair of narrow pulses of appropriate amplitude, each of which is filtered in linear filters 18, 20. The filter outputs are multiplied by sin w and cos wt the latter being subtracted from the former before transmission. At the receiver Fig. 6, incoming signals are demodulated respectively by cos wt and - sin w locally generated signals and passed through low pass filters, to remove double frequency terms. This recovers phase and quadrature waveforms which are sampled every T seconds. The carrier may be also extracted. As there may be intersymbol interference an adaptive equalizer may be incorporated. A system employing 16 4-bit combinations is described in the Specification, the bit combination represented by any point being in Gray code relation to adjacent points on the same ring. Vectors may have amplitude ratios of #2: 3: 3#2: 5.

IPC: B64F1/06
Filed: 1956-12-13
Abstract: 815,397. Launching aircraft RAYNAUD, C. Dec. 13, 1956 [Dec. 27, 1955], No. 38102/56. Class 4. [Also in Group XXI] Launching apparatus comprises a slideway 2 in which are arranged blocks 3 constituting chambers 4 for a propellant. The slideway has openings 5, Fig. 5, in which can slide ribs 6 extending from a body 1. Chambers 4, open towards the surface contacted by the body 1, are so inclined that gases issuing therefrom are directed forwardly of the apparatus. The blocks 3 are interchangeable and separated by packing of plastic or fibrous material, e.g. pressboard, to damp-out shocks and give fluid-tightness. The body 1 has in the base an elongated opening of the same width as the chambers 4 and leading to a gas-receiving chamber so shaped that the gases strike the front wall of the chamber and are deflected rearwardly to a nozzle 9 to give a rocket-thrust to the body 1. A rear deflecting wall 11, Fig. 4, may also be provided, the nozzle 12 then being of circular section, Fig. 5. Through grooves 32, Fig. 9, in the slideway flows a lubricant into which dips a wiper 31 on the ribs 6 to project the liquid on to the contacting surfaces. The liquid may be a solution or suspension of wetting agents (sulphonated fatty acids) and graphite in water. The gas-emitting substance placed in the chambers 4 may be a powder, liquid, explosive or pyrotechnic composition such as potassium chlorate 735 gms. hexamethylenetetramine 140 gms. and sulphur 96 gms. This composition may be placed in prepared cartridges placed in the chambers 4. The cartridges in successive chambers may have differing speeds of reaction according to the acceleration of the body 1 as it moves along the ramp, or the cartridges may contain differing quantities of the composition. In Fig. 7 a cartridge 13 contains a pyrotechnic composition 14 and a detonator 15 to be initiated by firing pins 16 when they are hit by strikers 17. Springs 21 stress the strikers away from the pins 16 until the strikers are forced inwards by pivoted fingers 18 rocked by cams 22 on the body 1. The cartridges may also be fired by a resistance wire when contacts are closed by the cams. When liquid propellants are used, these may be injected into the chambers 4 and electrically ignited, injection and ignition being controlled by a plunger on the body 1. A timing device may be used to bring the ignition out of phase with the passage of the front wall of body 1 over a chamber. Means may be incorporated to supply a volatilisable substance to the chambers 4. The apparatus may operate as a rocket or the gases may intitiate the reaction unit of a device launched from the ramp. The body 1 may have a hook 30 for attachment to a device which is to be launched by the apparatus, which may then be fitted with tracks for wheels or shoes of the device to be launched.

Title: Removal of metal contaminants from high boiling oils
IPC: C10G67/02
Filed: 1956-12-18
Abstract: Petroleum fractions boiling above 900 DEG  F. are treated to remove metallic and organic contaminants by hydrogenating at a temperature gradient within the range 750-825 DEG  F. at 400-300 p.s.i. and space velocity of 0.25-5.0 v./v./hr. in the presence of a sulphurinsensitive hydrogenation catalyst to form coky particles, removing the fraction from the catalyst, separating the coky particles from the fraction and recovering the decontaminated fraction.  The reaction is exothermic and it is preferred to operate with an outlet temperature about 50 DEG  F. higher than the inlet, e.g. with a heavy Texas crude the preferred temperature gradient is 750-800 DEG  F., and with Venezuelan crude the preferred temperature gradient is 775-825 DEG  F.  The process removes nickel, venadium, iron, which may comprise porphyrins and difficultly soluble carbonaceous material.  It may be applied to gas oils, reduced crudes, vacuum flasked crude petroleum residua, extract and raffinate fractions from solvent extraction of petroleum oils, fractions obtained by deasphalting crude petroleum fractions and other crude petroleum residua.  Suitable catalysts are cobalt or nickel molybdate, molybdenum oxide or sulphide, cobalt or nickel vanadtate, vanadium sulphide and cobalt, nickel or tungsten sulphide or mixtures thereof, supported on alumina, magnesia, carbon, zirconia or diatomaceous earth.  Suitable unsupported catalysts are cobalt, nickel, tungsten or molybdenum sulphides or mixtures thereof.  A fixed bed reactor may be used, or fluidized power type with the catalyst suspended in the vaporized feed-stock, or the catalyst may be suspended in the liquid feed-stock under high pressure conditions to form a slurry.

Abstract: 1,243,410. Vanadium pentoxide. SIEMENS A.G. 1 Aug., 1969 [13 Aug., 1968], No. 38595/69. Heading C1A. [Also in Division H1] The transition temperature at which the resistivity of vanadium dioxide exhibits a sudden change is shifted by the substitutional incorporation of both iron and tungsten, preferably in 1:1 atomic ratio. Both iron and tungsten may each be present in amounts up to 5 at. per cent of vanadium. The transition temperature of the composition may be as low as 0‹ C. To prepare the composition, vanadium pentoxide is first heated in hydrogen at 550‹ C. and is then heated at 1000‹ C. for 6 hours, to convert it to dioxide containing some trivalent metal. Vanadium pentoxide, iron III oxide and tungsten VI oxide are mixed in and the mixture is sealed in an evacuated capsule and heated at 1000‹ C. for 6 days. It is stated that any oxides of the metallic components may be used in this method to obtain the same product. A resistor is described in which a needle-like crystal of the resistance material is mounted on an insulating substrate and provided with electrodes. If a resistor made from the materials is fed from a constant current source its temperature is stabilized at the transition temperature (it operates with a low impedance channel within surrounding high resistance material) and the resistor may be used to thermostat other components. A superlattice structure is shown by these materials on one side of the transition temperature but not on the other. The material may be piezo-resistive (see Specification 1,239,333).
