Title: Improvements in or relating to oil burners
IPC: F23K5/20
Filed: 1934-11-19
Abstract: 445,724. Liquid-fuel burners. KALOROIL BURNERS, Ltd., and GOLDBERG, A., Victoria Road, Park Royal, London. Nov. 19, 1934, No. 33229. [Class 75 (i)] A pressure oil burner is mounted with part of its body arranged within an oil heater or an extension therefrom so that, heated oil will be circulated by convection around the burner when it is not in operation. The Figure shows an oil heater 8 having an extension 17 which projects into an air-tube 18 and is fitted with a cap 19 carrying the burner body 16. A tubular member 27 extending forwardly of the body 16 carries the burner jet 9 which may be fitted with a filter 30. Oil may be supplied to the heater 8 in the manner described in Specification 445,720, the fuel pump being controlled by a thermostat 32 so as to start only when the electric immersion element 15 has raised the oil to a predetermined temperature. The discharge of oil from the burner jet is controlled by a valve 21 opened automatically by the oil pressure assisting a spring 23 to overcome the resistance of a spring-pressed piston 25. Oil escaping past the piston 25 is drained off through ducts 26. A relief byepass 11 fitted with a leak valve allows surplus oil to return to the fuel tank. In a modification the cap 19 is integral with the extension 17 which is formed with an aperture to receive the burner.

Title: Improvements in or relating to fibrous webs and cigarette filter plugs made therefrom
IPC: B01D39/14
Filed: 1960-09-29
Abstract: A cigarette filter plug formed from fibrous material has at least a third of its individual fibres laid transversely of the plug.  The fibres are preferably of cotton or viscose and may be bleached prior to formation of the web by chlorine treatment for about 30 minutes at a temperature not exceeding 24 DEG C., followd by rinsing, about 3 hours in a peroxide bath at 85 DEG C., passage through an acid bath, further rinsing, washing, and drying.

Title: Improvements in, and relating to, valves
IPC: F16K17/04
Filed: 1927-12-13
Abstract: 313,860. Mason, H. L. Dec. 13, 1927. Fluid - actuated valves. - Automaticallyoperated fluid-pressure valves, such as safety, reducing, or regulating valves, comprise a main valve adapted to be operated by fluid pressure operating against a load, or vice versa, and a supplementary valve-like actuator arranged on the fluid-pressure side of the main valve and whose relation to the load is adjustable independently of the load and of the fluid pressure. In the arrangement shown the main valve e is loaded by a helical spring or a spring acting through levers and toggle links, and is opened initially by boiler pressure in the passage d acting directly on the valve. The consequent drop of pressure below the valve e, assisted preferably by the hollow cone s below the valve e, unbalances the actuator-disc f, which then takes up the load and gives a high and quick lift. The relative areas of the disc f and valve e may be arranged to obtain a re-seating of the valve e with a small drop of pressure below the disc f. The axial distance between the valve e and actuator-disc can be adjusted by the coaxial spindle g, as shown. The above arrangement may be used as an auxiliary valve to control the opening and closing of a piston-actuated main valve.

Filed: 1922-12-12
Abstract: 212,633. White, A. E., (Brewster Goldsmith Corporation). Dec. 12, 1922. Drawings to Specification. Sparking-plugs.-The combustion space within the inner end of a plug, the area of the surfaces which bound it, and the aperture by which it communicates with the cylinder are determined according to the compression ratio of the engine. The combustion space and area are varied approximately in inverse proportion to the compression ratio. For ratios higher than 5 to 1 volumes are specified of from 1.25 to 0.50 c. cm., and areas of from 15 to 3 sq. cm. For ratios between 5 to 1 and 3 to 1. the corresponding volumes are 1.25 and 1.75 c. cm., and the surface areas range from 13 to 36 sq. cm. The area used in practice is the area as determined from the above figures, modified according to the heat capacity, conductivity, &c. of the materials employed. When, for example, the working temperature of the electrode is 1900‹ F. absolute, and that of self-ignition of the fuel is 1135‹ F. absolute, the area of the surface is increased in the ratio of 1900 to 1135 beyond that determined from the above figures. The net cross-sectional orifice area is determined from the formula O = Kr<n> where 0 and r represent the area and compression ratio, and K and n are constants to be determined experimentally by using plugs of differing orifice and engines of differing compression ratio.
