Filed: 1962-07-25
Abstract: 975,204. Equalizing arrangement for brakes. VAUXHALL MOTORS Ltd. July 25, 1962, No. 28577/62. Heading F2E. A brake control system for motor road vehicles having twin axles carrying two pairs of wheels comprises a single actuator member operative through primary and secondary equalizer devices between pairs of wheels on the two axles and between two wheels on each axle respectively. One of the equalizer devices is constituted by a sheathed cable while the other is constituted by a pair of levers on a common floating-pivot rotatable shaft. As shown, the common control lever actuates the brakes on the wheels 5, 6, 7 and 8 through the cable 21 which causes the rear yoke lever 16 mounted on the rear shaft 15 to rotate counterclockwise to actuate the brakes on the wheels 6 and 8 through the lever 17 rigid with the rear shaft 15. The outer sheath 22 of the cable, the front of which abuts a fixed bracket 23, acts on the front yoke lever 16 to which it is pivotally attached to rotate the front shaft 15 clockwise to actuate the brakes on the wheels 5 and 7 through the lever 17 rigid with the front shaft. The two shafts 15 are mounted in brackets 11 and 12 secured to the frame member 1 so as to be movable transversely in slots 9.

Title: Drag line scraper
IPC: E02F9/28
Filed: 1949-11-08
Abstract: 663,687. Excavating earth. LORD, F. E. (Eimco, Corporation). Nov. 8, 1949. No. 28585/49. Class 68 (i). In a drag-line scraper the scraper blade 14 is bolted to a back plate 13 welded to the vertical portions 12 of a pair of diverging arms 10, 101 that are joined together to form a nose portion 11. The drag-line 18 is secured to and passes through an anchor 16 formed on the back plate and proceeds to the hauling unit through an eye 19 formed on the nose so that as tension is applied to the drag-line the angle which the blade makes with the ground increases as the blade is rotated relatively to the anchor in a direction opposite to that of the direction of pull of the drag-line until prevented by the increasing lifting action of the drag-line that is applied to the eye. In a modified form a spring unit is interposed between the tail of the drag-line and the anchor and 'a stop on the drag-line abuts against the eye after the spring has stretched a predetermined extent so that only a certain limited torque can be applied to the scraper.

Filed: 1924-12-01
Abstract: 241,410. French, L. O. Dec. 1, 1924. Cylinders receiving liquid fuel.-Fuel supplied by gravity or pressure is admitted during the air admission period through a valve 18 to a chamber 9, which is in communication through a series of orifices 12 with a passage 11 connecting the engine cylinder with an ignition chamber 10. During the compression stroke the fuel in the chamber 9 is wholly or in part t vaporized, and a portion of the vapour enters the chamber 10 through the orifices 12, and is ignited therein, the consequent increase in pressure in the chamber 10 serving to inject the remainder of the fuel from the chamber 9 into the cylinder. The fuel is supplied past a rnanaally or governor controlled needle valve 19, and air enters with the fuel through a passage 34, this air being drawn either from the atmosphere in the case of a fourstroke engine or from the scavenging air in the case of a two-stroke engine. The valve 18 is actuated with the main air admission valve, by a lug 21 on the rocking arm 22. The orifices 12 are formed in a detachable sleeve 27, which in a small engine may be formed integral with the chamber 10, and in a large engine may be water cooled. In a modified construction, thei chamber 10, which is uncooled is situated on the cylinder axis, fuel is injected by means of a pump into the chamber 9, and a plate having a number of small orifices is provided for the lower end of the passage 11. The invention is equally applicable to four-stroke or two-stroke engines.

IPC: G03C5/18
Filed: 1928-10-09
Abstract: 324,048. Halden & Co., Ltd., J., and Holden, J. Oct. 9, 1928. Diazotype processes.-To increase the contrast between image and background and to prevent discolouration, printing materials sensitized with diazo-compounds are treated after exposure and development with a solution of an acid inorganic reducing agent such as sodium metabisulphite or stannous chloride. In an example, a print, after development by a coupling agent, such as the anilide of 2 : 3 oxy-naphthoic acid which in alkaline condition is strongly yellow-coloured, is treated with a solution of stannous chloride preferably containing a little tartaric acid whereby the yellow colour is discharged. It is stated that a developed print treated according to the invention more readily permits of alterations and additions being made to the original image in ink. The Provisional Specification states also that developed prints may be treated with reducing agents such as sodium sulphite in neutral or acid condition. Specifications 294,972 and 295,993 are referred to.
