In a hydraulic brake system for vehicles, the brakes are applied at low pressure by a first movement of the brake pedal 32, which through linkage 53, 46 causes a valve rnember 61 to shut off the return to a reservoir 14 of the delivery from a continuously running pump A and later to open a non-return valve 59 to allow pressure to be supplied from an accumulator B. Further movement of the pedal sufficient to take up play " a " in a lost-motion connection 52, causes rod 94 to be moved so that a disc 80 on the vehicle transmission shaft engages the extensible pulley 78, Fig. 5, of a servo-device wherein centrifugal weights 88 fly apart to cause actuation of a servo-hydraulic piston and cylinder unit 69, 70 which is disposed in the hydraulic line to the brake cylinder 5 and thus the pressure therein is further increased to a much higher pressure. By this arrangement the accumulator B may be only required to supply a relatively low pressure or may be omitted from the system altogether.

Abstract: 1,032,348. Brake adjusters. BENDIX CORPORATION. May 7, 1964 [May 15, 1963 (2)], No. 19064/64. Heading F2E. An automatic adjuster for a drum-brake comprising a cable 30 connected by a cage 32 to a lever 36 so as to cause the latter to rotate a serrated wheel 21 operating a screw-and-nut adjuster 16 for brake shoes 12, 14 is characterized by a resilient element 34 stretched between points 46 and 54 on the cage and which at 54 connects with the lever 36 as well so as to allow relative movement at that end between the cage and the lever. The cable 30 is hooked to a pin 22 fixed on the backing plate and passes around a guide 31 on the shoe 14. A spring 38, weaker than the spring 34, tends to rotate the lever 36 away from contact with the wheel 21. When the brake shoes are applied by the fluid motor 24 tension is induced in the cable 30 which causes the lever to rotate the wheel 21. Reaction from the shoes increases on the strut 16 until the screw 20 jams in the nut and turns no further and subsequent increase in tension is taken up by the spring 38. Figs. 3, 5 and 7 illustrate embodiments in which the invention is applied to other constructions of shoe-drum brake.

Title: A process for the preparation of addition compounds of hypochlorous acid or hypobromous acid with unsaturated organic compounds
IPC: C07C29/66
Filed: 1932-07-07
Abstract: Addition compounds of hypochlorous or hypobromous acid with organic compounds having one or more double carbon linkages in the molecule are manufactured by reacting the said unsaturated compounds in the presence of water with hypochlorous or hypobromous acid esters of tertiary alcohols (obtainable by passing chlorine or bromine into a mixture of water, tertiary alcohol, e.g. tertiary butyl or amyl alcohol, and alkali hydroxide or other basic substance).  As organic compounds having one or more double carbon linkages in the molecule may be employed aliphatic olefines, e.g. ethylene, propylene or butylene, cyclic olefines, e.g. cyclohexene or pinene, diolefines, e.g. isoprene, oleic acid, cinnamic acid, eugenol, citral, allyl alcohol or crotonic acid.  In a modification of the process, the hypochlorous or hypobromous acid esters of tertiary alcohols are caused to react in the presence of water on tertiary alcohols, which give rise to the formation of unsaturated hydrocarbons and water.  In examples: (1) ethylene is introduced into a vessel provided with a gas-tight stirrer, a thermometer and a sieve-plate, containing water and the hypochlorous acid ester of tertiary butyl alcohol (obtainable from tertiary butyl alcohol and hypochlorous acid), yielding ethylene chlorhydrin; (2) a mixture of tertiary butyl alcohol containing water and the hypochlorous acid ester of tertiary butyl alcohol is refluxed to produce isobutylene chlorhydrin; (3) propylene is reacted as in (1) producing propylene chlorhydrin.  Samples have been furnished under Section 2 (5) of: (1) isoprene dichlorhydrin, produced by reacting isoprene in ice water with the hypochlorous acid ester of tertiary butyl alcohol; (2) cyclohexene chlorhydrin (2-chlorocyclohexanol-1), produced similarly from cyclohexene; (3) cyclohexene bromhydrin (2-bromocyclohexanol-1) produced similarly by employing the hypobromous acid ester of tertiary butyl alcohol (obtained by adding bromine to aqueous tertiary butyl alcohol in the presence of yellow mercury oxide); (4) oleic acid chlorhydrin (9 : 10-chloroxystearic acid) produced by reacting potassium oleate in ice water with the hypochlorous acid ester of tertiary butyl alcohol and liberating the acid by means of nitric acid; (5) cinnamic acid chlorhydrin (phenylchlorolactic acid) produced by reacting potassium cinnamate in ice water with the same ester and liberating the acid by means of hydrochloric acid; w-chlorostyrene is obtained as a bye-product.  The Specification as open to inspection under Sect. 91 comprises also the formation of the hypochlorous or hypobromous acid esters of tertiary alcohols in situ by bringing together the tertiary alcohol, water and chlorine or bromine, preferably in a weakly alkaline medium.  This subject-matter does not appear in the Specification as accepted.
