Patent FR-2249877-A1 (FR)
IPC: C07C205/47
Filed: 1974-10-25
Abstract: Alpha-dihydroxyanthraquinones used as intermediates in the synthesis of many dyestuffs, such as the Alizarin Saphirols (e.g. Color Constitution No. 63000, 63005, 63010, 63011, 63315 and 63610) can be replaced on an equimolar basis by alpha-di(lower alkoxy)anthraquinones. The alpha-di(lower alkoxy) anthraquinones can be converted in a single step, by treatment with oleum, to the corresponding alpha-dihydroxyanthraquinone-beta-disulfonic acids in almost quantitative yield. The corresponding diamine is obtained by dinitrating followed by reduction of the nitro groups. The known intermediate, leuco 1,4,5,8-tetrahydroxyanthraquinone (see C.I. No. 62500) can be obtained either by reduction of the diamine or by reduction of the dinitro compound. In one embodiment, the alpha-di(lower alkoxy)anthraquinone is obtained from dinitroanthraquinone by treatment thereof with methanol and KOH.

Title: Cone piston brake expander - has piston length automatically adjusted to take upe wear of linings
IPC: F16D65/56
Filed: 1975-01-03
Abstract: The cone piston expander mechanism has piston length increasing if the cone penetrates beyond a certain distance between the pistons. Such expanders are frequently used in drum brakes where the piston extension would be used to compensate for wear in the linings. Each piston crown (34, 35) is grooved to locate on the brake shoe and is thereby prevented from rotating. The crowns are mounted in screw threads in the piston bodies and each of the latter has teeth cut on the outside of the base of the skirt. The teeth mesh with gears mounted on a transverse shaft which is driven by a ratchet system. A projection on the end of the cone (10) which expands the pistons (18, 19) via rollers (12, 13) and ramps (16, 17) rotates the pawl (25) carrier by a pin (21) locating in a slot (22). When the lining wear beyond a certain point, the pawl can pass over one more tooth, (36) on the ratchet as the brakes are applied. When the brakes are released, the ratchet then rotates the pistons automatically screwing out the crowns.
