Abstract: 485,440. Supplying liquid fuel. AEROPLANI CAPRONI SOC. ANON., and FUSCALDO, O. Sept. 7, 1937, No. 24365. Convention date, Sept. 14, 1936. Addition to 481,786. [Class 7 (iii)] In an engine having an electromagnetic fuelinjection valve as described in the parent Specification, the operation of the pump for supplying fuel to the valve is modified by subjecting the pump piston to the air pressure in the induction pipe, instead of to the pressure in the engine cylinder. The Figure shows a fuel injector 6<1> actuated by an electromagnet 6 and supplied with fuel through a pipe 20 by a pump 12 having a differential piston 9, 10, the larger portion 9 of which is in communication with the air intake 3 by a pipe 15 opening at 16 on the engine side of the throttle valve 4. The other side of the piston 9 is open to atmosphere at 17, or, if a compressor is used, is connected by a pipe 18 to the other side of the throttle valve. When the inlet valve 2 is opened, the depression caused at 16 operates the fuel pump to supply a charge of fuel. After the valve 2 closes, the fuel pump is returned by a spring 24 and draws in a fresh charge through a pipe 22 and port 23. The action of the spring 24 is varied by an opposing spring 25, which is adjustable by means of a screw abutment 26 actuated manually or automatically, so as to prevent increase in fuel injection when the engine speed decreases due to closing of the throttle valve.

[Class 138(ii)] The clothes in the washing chamber 1 of a washing-machine are exposed to propulsive currents of liquid through mouthpieces 2, 3 which are arranged in staggered relation on the opposite sides of the chamber 1 and are disposed so that, where they enter the chamber, their cross-section increases in width from the bottom of the section upwards, in the case of the mouthpieces on one side of the chamber, and, in the reverse direction, in the case of the mouthpieces on the other side of the chamber. Each mouthpiece may be of elongated tubular section as shown at a, Fig. 1, or be built up of a number of tubes of gradually increasing cross-section as shown at b. The lower part of the chamber 1 is connected to a pump 4 which may be of diaphragm, piston, or other type. As shown in Fig. 1, the piston 6 of the pump 4 is connected by a rod 7 to a pivoted lever 9 which is actuated by a rotary cam 10 against a spring 11. The cam is adapted to push the lever 9 downwards and then suddenly to release it, whereupon the spring 11 causes the piston to force the washing liquid through the mouthpieces 2, 3. A screw 13 regulates the tension of the spring 11, and thereby controls the force of the liquid discharge. A heating-element 15 may be arranged around the upper part of the pump housing. In the modification shown in Fig. 3, the washing chamber is of ring- shape in cross-section with the mouthpieces 2, 3 obliquely disposed in staggered relation in the inner and outer walls of the chamber.

Abstract: 1451677 Electrodes for alkaline accumulators BATTELLE MEMORIAL INSTITUTE 5 June 1974 [7 June 1973] 25037/74 Heading H1B [Also in Division C7] A nickel hydroxide electrode for galvanic cells is made by coating a porous organic core having a fibrous or reticulated texture with powdered Ni or a decomposable Ni compound. The coated core is then heated to remove the core and sinter the Ni powder prior to depositing nickel hydroxide in the pores. The core may be a felt or non-woven material of natural or synthetic fibres or reticulated plastics foam e.g. polyacrylonitrile, polyester, polyamide, polypropylene, polyether, and polyurethane. The Ni or compound powder is < 50 microns, average diameter 10 microns and coating is effected by fluidized bed, or spraying as a suspension in a liquid or gas. The coated core is then heated to at least 700‹C in an oxygen containing atmosphere and then at 800-1200‹ in a reducing atmosphere. The sintered body is then impregnated with a nickel salt solution and treated with an alkaline solution to form nickel hydroxide. Alternatively the body may be polarized cathodically in an aqueous solution of nickel nitrate and nickel hydroxide at pH 5-7 and current density 0.05A/cm<SP>2</SP> or the nickel hydroxide may be introduced by electrophoresis or deposited from a suspension. 0.5-1 wt. per cent lithium may be introduced by adding lithium hydroxide with the nickel hydroxide.

Title: Improvements in and relating to the sulphonation of benzene and to the extraction ofgaseous sulphur trioxide
Inventor: MILNER DAVID WILLIAM
IPC: C07C309/29
Filed: 1952-10-07
Abstract: Benzene monosulphonic acid or benzene-m-disulphonic acid is prepared by dissolving sulphur trioxide in liquid benzene monosulphonic acid, and reacting the dissolved sulphur trioxide with benzene or with the liquid benzene monosulphonic acid.  The reaction with the sulphur trioxide may take place at a temperature below that at which substantial sulphonation of the benzene monosulphonic acid takes place, e.g. at a temperature below 80 DEG  C.  The process may be modified in that up to 13 per cent concentration by weight of sodium and/or potassium benzene monosulphonate is added to the benzene monosulphonic solvent to depress its melting-point.  A stoichiometrical excess of benzene may be added to the sulphur trioxide solution to form benzene monosulphonic acid, after which the excess benzene is converted to benzene monosulphonic acid by the addition of a stoichiometric proportion of sulphur trioxide. The benzene m-disulphonic acid is preferably formed by heating the solution of sulphur trioxide in the liquid benzene monosulphonic acid.  The sulphur trioxide solution may be formed by scrubbing gases resulting from the combustion of sulphur with liquid benzene monosulphonic acid, e.g. at a temperature below 100 DEG  C., preferably below 80 DEG  C., where benzene monosulphonic is the final product, and at a temperature exceeding 100 DEG  C. where benzene-m-disulphonic acid is the final product.  When the sulphur trioxide is provided by the gases leaving the converters of a sulphuric acid plant, the gases are cooled to about 250 DEG  C., further cooled by heat exchange with a solution of sulphur trioxide in liquid benzene monosulphonic acid and then scrubbed with liquid benzene monosulphonic acid.  The process may be carried out in a continuous manner by continuously scrubbing sulphur trioxide from gases resulting from the combustion of sulphur with liquid benzene monosulphonic acid at a temperature below 100 DEG  C., preferably below 80 DEG  C., continuously feeding benzene to the resulting scrubbing liquor, and maintaining the resulting mixture at a temperature below 100 DEG  C., preferably below 80 DEG  C., to allow the formation of benzene monosulphonic acid.  The above continuous process may be modified in that the scrubbing is carried out with liquid benzene monosulphonic acid at any temperature, and the resulting solution is heated by part at least of the combustion heat contained in the gases to form benzene-m-disulphonic acid continuously.  A number of detailed examples are given.ALSO:Sulphur trioxide is extracted from mixtures of sulphur trioxide with oxygen and/or nitrogen by scrubbing the gas mixtures with liquid benzene sulphonic acid to dissolve the sulphur trioxide.  The gas mixture may be derived from the converters of a pyrites or sulphur-burning plant such as in a sulphuric acid plant.
