Abstract: 1,227,937. Antiskid control systems. KELSEY-HAYES CO. 20 March, 1969 [27 Sept., 1968], No. 14837/69. Heading F2F. In a pumped fluid pressure brake system the skid-sensor controls a valve admitting fluid pressure to the drivers-brake-valve to move it from its application to its release position. As described separate systems are provided with electric sensors to determine front and rear wheel skid conditions Fig. 2. Hydraulic system.-The driver's brake control comprises four valves 46, 48, 50, 52 with a common actuating bar 55. Pumps 100, 106 each supply fluid to one front and one rear control valve associated with one shoe actuator in both front and rear drums respectively, Fig. 1. One of the control valves is shown in greater detail in Fig. 3. Operation of the brake pedal acts through feel spring 66 on piston 54 which moves left to engage piston valve 56 allowing pressure to flow from inlet 14 to brake line 118 (see also Fig. 1). As brake pressure builds up to pedal pressure, piston 54 is moved right against springs 66 allowing valve 56 to close. Double springs in the front control valves make allowance for weight transfer on braking. The electric "skid-signal" energizes torquemotor 38 to rotate shaft 140 and move bladespring-biased actuating lever 142 down thereby raising shuttle-valve-element 156 to allow fluid to flow past lower seat 162 through passages 166, 96 to chamber 94 around piston 54 which is forced back to release brake pressure through bore 70 in piston valve 56 and via port 128 to reservoir. A check valve holds pressure on piston 54 until deceleration signal on torque motor 38 reduces to allow shuttle valve 156 to open the upper port 164 relieving pressure on piston 54 (via port 168 to reservoir).

The tertiary carboxamide may itself be used as the non-aqueous solvent, preferred such compounds being dimethylacetamide, dimethylformamide and N-methyl-2-pyrrolidone. The water is removed from the reaction mixture either chemically or physically. Chemical methods involve the use of a non-interfering drying agent which may be included in the reaction mixture or used externally to dry the refluxing solvent. Internal agents may be dimethoxypropane or an alkanoic acid anhydride or a sulphonic acid anhydride or a sultone, the latter two agents also representing substances which form the acid condition providing sulphonic acid, of the inventive process. Suitable external drying agents may be anhydrous magnesium sulphate, sodium sulphate or calcium chloride or calcium carbide or molecular sieve materials. These are usually employed in conjunction with physical removal of the water by azeotropic distillation, whereby a watercontaining azeotrope is distilled out of the reaction mixture during the heating operation. Such azeotropes are produced by including a suitable azeotrope-forming liquid, e.g. aromatic hydrocarbons, haloalkanes, or alkanes, in the reaction mixture and distilling off the aqueous azeotrope, when it may be dried by passage over a drying agent and the water-free solvents then re-cycled to the reaction mixture. The preferred acid is methane-sulphonic acid or its precursor methanesulphonic anhydride or 1,3 -propane - sultone. Reference has been directed by the Comptroller to Specification 1,204,972.
