Title: Improvements in and relating to motor fuels
Inventor: MACKENZIE COLIN GORDON
IPC: C10L1/18
Filed: 1954-02-04
Abstract: A motor fuel which does not produce deposits in the fuel inlet systems of internal combustion engines comprises hydrocarbons of the gasoline boiling range and not more than 2 per cent by weight of a hydrocarbon lubricating oil containing an oil-soluble salt of an aromatic or cycloaliphatic carboxylic or sulphonic acid or of a phenol with a metal of Group II of the Periodic Table. According to a modification of the invention, instead of a Group II metal salt of a phenol, there is employed a Group II metal salt of a condensation product of a hydrocarbon-substituted phenol containing at least 4 carbon atoms in the substituent with formaldehyde, acetaldehyde or a polymer thereof.  The hydrocarbons of the gasoline boiling range may comprise catalytically or thermally reformed or cracked gasolines, or mixtures thereof, straight-run gasolines, and fuels consisting of or comprising benzene or toluene.  Blends of gasoline with benzene, toluene, alcohols or ethers may also be employed.  The hydrocarbon lubricating oil may be a residual or distillate mineral oil, a polymerized olefin, an alkylated aromatic compound (e.g., poly-tertiary butyl naphthalene) or a mixture of such oils.  Group II metals mentioned are calcium, zinc, beryllium, magnesium, strontium, cadmium and mercury, and normal or basic salts of these metals, or mixtures thereof, may be employed.  The motor fuel may contain organo-metallic anti-knock agents such as tetraethyl lead, iron carbonyl and dicyclopentadienyl iron, and also scavengers for such compounds.  When the motor fuel is leaded, it may contain a halo-hydrocarbon scavenger such as ethylene dibromide, ethylene dichloride, acetylene tetrabromide hexachloropropylene, the mono- or poly-halo propanes, butanes or pentanes, and mono- or poly-halo alkyl benzene.  Mixtures of halohydrocarbon scavengers, such as a mixture of ethylene dichloride and ethylene dibromide, may be employed.  The motor fuel may also contain additives for modifying the nature of combustion chamber deposits (e.g. organic esters of oxyacids of phosphorus) and antioxidants (e.g. 2, 4-dimethyl-6-butyl-phenol). In the examples, gasoline compositions are described containing mineral lubricating oil and zinc 3, 5-di-isopropyl salicylate or the calcium salt of mixed alkyl salicylic acids containing 14-18 carbon atoms in the alkyl groups.  According to the Provisional Specification, the Group II metal salts may be added to the motor fuel in the absence of the lubricating oil.

Title: Improvements in or relating to echo ranging systems
IPC: G01S1/72
Filed: 1955-03-29
Abstract: 781,996. Echo distance measuring. ATLASWERKE AKT.-GES. March 29, 1955 [March 29, 1954], No. 9186/55. Class 118 (2). A system for the recording of objects encountered along the course of a ship by the reflection of compressional waves comprises an array of directional transducers arranged to cover a forward sector by their adjoining directional pattern lobes, with switching means for sequentially and singly energizing said transducers for a short time, and other switching means operated with a constant time delay in relation to the first switching means for sequentially and singly connecting said transducers to a receiving amplifier the output of which is connected to a recording stylus which is rotated on a circle in angular conformity to the varying direction of reception of echoes and produces markings on a moving recording strip in correspondence to received echoes, and means for controlling the feed of the recording strip to be in the same constant ratio to the ship's speed as the radius of rotation of the stylus is to the distance from which echoes are recorded. Transducers S<SP>1</SP>, S<SP>2</SP> ... Sn, arranged to cover a total forward sector of angle 2α, are connected to contacts 23 which are energized from oscillator 28 via rotating contact 24. A second rotating contact 25 is arranged to sweep contacts 23 at an angular distance # behind rotating contact 24. Echoes received by contact 25 are fed via an amplifier 30 to stylus 5 which is driven in a circular path over recording paper 3 by means of a motor 20. Synchros 18 and 19 ensure that the rotating contact 25 is moved in synchronism with stylus 5. The recording paper 3 is driven by a motor 32 controlled at 33 such that its speed shown on indicator 34 is proportional to the speed of the ship. Transmission gearing could be used to derive. this feed directly from a log. By making the ratio of paper feed to ship's speed the same as that between the radius of rotation of stylus 5 and the echo distance corresponding to the angular delay # the record is a conformed representation of the ship's surroundings in which the centre of rotation corresponds to the ship's momentary position. Multiple contacts 25 may be provided at different values of angle #, each connected via an amplifier to its own stylus 5 arranged at a distance from the centre of rotation proportional to the angle #, i.e. on a spiral originating at the centre. More efficient coverage of a broad strip may be provided by combining the above system with two systems for scanning in range along lines which are at right angles to the fore-and-aft line of the ship. In this case two highly directional transducers are fixedly mounted on the port and starboard sides of the ship respectively and two associated styli are arranged to move in opposite directions along two rectilinear guides disposed at right angles to the length of the recording strip, leaving an unscanned central zone near the course of the ship which is filled in by the arcuate scan of, say, Œ 15 degrees.

Title: Improvements relating to the purification of crude zirconium compounds or ores
IPC: C22B34/14
Filed: 1942-07-03
Abstract: 559,117. Zirconium compounds. EVERY. C. E. (Titanium Alloy Manufacturing Co.). July 3, 1942, No. 9244. [Class 1 (iii)] Crude zirconium compounds are purified by precipitating zirconium oxysulphate by heating to 40-85‹ C. a solution containing zirconyl ions, sulphate ions, ions of an acid, e.g. hydrochloric, which is more readily decomposed than sulphuric acid, and basic ions other than zirconyl ions. The total basic ions should be at least equivalent to the total acid ions, but alkali metal ions should not be more than equivalent to the sulphate ions. The solution should contain 100-400 grams per litre of zirconium dioxide. If the silica content of the crude ore exceeds 10 per cent it should be reduced by fusing with excess caustic soda and leaching with water, or by heating in presence of carbon to a temperature sufficient to volatilize the silica. The ore is rendered soluble by fusing with alkali and/or alkaline earth oxides, hydroxides, carbonates, or sulphates, and the product is leached with water to remove soluble impurities and excess alkali metal compounds. The residue is dissolved in hydrochloric acid, with or without sulphuric acid, and salts are added to introduce the necessary sulphate and basic ions. The ratio of zirconyl to sulphate ions should be between 5 to 2 and 5 to 3. The precipitated oxysulphate may be calcined above 900‹ C. to form zirconium oxide.
