Title: Improvements in or relating to Preparing Pigment Zinc-oxide.
IPC: C01G9/02
Filed: 1918-12-05
Abstract: 122,170. American Zinc, Lead, & Smelting Co., (Assignees of Wemple, L. E.). Jan. 9, 1918, [Convention date]. Pigments.-A process for preparing pigment zinc oxide, free from coloured oxides of lead and cadmium and from soluble zinc salts such as zinc sulphate, consists in first producing: by oxidizing in the presence of sulphur a crude zinc oxide containing a small proportion of zinc sulphate and having any lead and cadmium present as sulphates also, and then treating this crude product with a reducing agent such as carbon under such temperature conditions that the zinc sulphate is eliminated or decomposed whilst the lead and cadmium sulphates remain unchanged. The sulphated crude zinc oxide may be obtained as the immediate product of the usual volatilization process if the raw material contains sufficient sulphur; otherwise, sulphur may be added to the raw material, or the volatilized product may be treated with sulphur. A convenient reducing agent is lampblack, mixed with the crude oxide in the proportion of one to two per cent., the mixture being heated for about half an hour at a temperature between 900 and 1200‹ F., preferably in a muffle to prevent contamination with fuel ash. The material is then stirred with free access to air to burn off any remaining excess of carbon and to facilitate the escape of sulphur dioxide and other excluded gases. The stirring and consequent rapid cooling prevent agglomeration of particles and the formation of crystalline compounds. Some grades of crude oxide produced by volatilization furnaces contain appreciable amounts of carbon or other reducing agents, and the necessity for adding a reducing agent for eliminating the zinc sulphate may be avoided by regulating the volatilization process so that the crude oxide contains either sufficient carbon to permit direct heating, or excess carbon adapted for admixture with other grades deficient in carbon. It is possible to use as the reducing- agent oxide of lead or cadmium or other metal having a white sulphate, but such oxides must be used in carefully regulated quantities as a slight excess would discolour the final product. The pigment zinc oxide prepared by this process contains lead solely as insoluble white sulphur compounds, and sulphur in insoluble form in excess of that required to sulphatize the lead present, probably as zinc sulphide or basic zinc sulphate. Methods of testing the colour, fineness, covering power, and oil-absorbing capacity of the pigment are described.

Title: Liquid fuel compositions
IPC: C10L1/18
Filed: 1958-06-27
Abstract: A hydrocarbon fuel of the gasoline boiling range contains a lithium salt of an organic acyclic branched carboxylic acid, the carboxy group of the acid being attached to a methylene group in an aliphatic radical.  Suitable acids are C5 to C18 acids and are exemplified by 3-methyl-, 3,3-dimethyl-butanoic acids; 3-methyl-, 4-methyl-pentanoic acids; 4,5-dimethyl-, 3-ethyl-, 4-tert. butyl-, 3,5,5-trimethylhexanoic acids; 3-methyl-, 6-methyl-3-isoamyl-, 6-methyl-3-propyl-3-isoamyl-heptanoic acids; and iso-octanoic acids produced by oxidising a mixture comprising isomeric primary alcohols of 8 C. atoms having no branching on the 2-carbon.  The lithium salts may be added directly to the fuel or they may be introduced separately into the combustion chamber of the engine; thus they can be added with water/alcohol mixtures for use in aircraft engines or with tetraethyl lead/alcohol mixtures for use in automotive engines. The salts are said to be effective in unleaded fuels as well as in fuels containing up to 6.0 ml. of tetraethyl lead per U.S. gallon. Sufficient salt is added to give 0.005 to 2.0 gm. of lithium per U.S. gallon of fuel.  Unspecified fuel additives may also be incorporated in the fuel, e.g. dyes, rust-inhibitors.  Blending agents to enhance the solubility of the salts in the fuel, e.g. unspecified alcohols, glycols, esters, ketones and amides, may also be included.

Patent GB-444454-A (GB)
Title: Improvements in and relating to impulse generators employing electric discharge devices
IPC: H03B19/12
Filed: 1935-07-22
Abstract: 444,454. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. July 22, 1935, No. 20777. Convention date, July 21, 1934. [Class 40 (v)] The grid of an impulsegenerating valve is rendered negative in response to the flow of plate current, there by preventing further flow, and the negative charge on the grid condenser is subsequently reduced by a succession of periodic impulses, until plate current is reestablished and the cycle repeats itself. The Figure shows the circuit employed when the valve is of the discontinuous control type. The plate circuit of the valve includes a resistance 14 and an alternating or pulsating supply source 10. During a positive half-cycle of plate potential, plate current through the resistance 14 establishes a negative potential at the tapping point 17 and gives a negative charge through a rectifier 16 to the grid side of the condenser 15 which is connected across the grid and cathode of the valve. Plate current is thus cut off, and the subsequent positive half-cycles of plate voltage produce no current until the charge on the condenser 15 is removed or sufficiently reduced. This removal is effected by a succession of positive impulses applied from a supply transformer 18 through a rectifier 23 and high resistance 20. In this way the frequency of the plate current pulses, which may be taken off from terminals 11, is an integral fraction (say one-fifth) of the supply frequency. The frequency generated is varied by adjusting the tapping 17. In a modification using a hard valve (Fig. 3, not shown), the plate circuit includes the primary of a transformer, the secondary of which serves to charge the condenser 15 through the rectifier 16. Specification 408,624 is referred to.

Abstract: 385,342. Rockets. ZWERINA, R., 5, Brigittagasse, and STOLFA, H., 30, Harteckerstrasse, both in Vienna. July 21, 1931, No. 20836. Convention date, July 28, 1930. [Class 9 (ii).] The propellant charge 4, Fig. 3, of a rocket 1 consists of a single hollow body which is closed at one end and open at the other and which is divided into a number of compartments 8 by the insertion of one or more plugs 7. The plugs may consist of a combustible substance which may be of the same composition as the propellant charge. By altering the positions of the plugs, the area of the burning surface of any compartment may be altered. Ribs 16, or grooves, may be provided to increase the burning surface. The compartments may be loosely filled with a propellant charge or with an illuminating composition. The speed of the rocket during flight may also be controlled by varying the composition of the charge 4 from compartment to compartment. In the modification shown in Fig. 2, the exhaust orifice 3 is formed in a combustible insertion 15 and gradually increases in size as the insertion burns during flight. The Specification as open to inspection under Sect. 91 describes also a construction comprising a number of rockets connected end to end in such a manner that when one rocket is burnt the corresponding part of the casing detaches itself from the remainder. In the form shown, two rockets 1, 2, Fig. 4 (Cancelled), are interconnected by two discs 13 of celluloid, and are provided respectively with insertions 14, 12, which constitute the walls of the exhaust openings. The opening in the insertion 14 is normally closed by a solid plug 7 of a combustible substance. This plug serves to ignite the charge of the rocket 1 when the charge in the rocket 2 has completely burnt out. Grooves 17 are provided to increase the area of the burning surface. In another modification, a spring-actuated valve is arranged to cover the exhaust orifice in order to regulate the flow of the propulsive gases. This subject-matter does not appear in the Specification as accepted.
