Title: Controlling braking force in a wheel brake system on a powered vehicle
IPC: B60T8/28
Filed: 1970-08-26
Abstract: 1326616 Anti-skid braking systems AISIN SEIKI KK 26 Aug 1970 [26 Aug 1969] 41094/70 Heading F2F In a vehicular braking system with antiskid control the brake reaction at an actuator 20 of one wheel 21 is used to control the braking effort at the other 28 when the wheel 21 commences to skid. In normal braking fluid pressure passes from pressure chambers 15, 16 of a dual master cylinder 10 to the actuator 20 through pipe 19 and to an inlet 25 of a brake pressure limiting valve 24 respectively. Fluid under pressure passes into an actuating chamber 22 of actuator 20 to expand two pistons 61, 62 which actuate the shoes of a drum brake, rightward movement of piston 62 causing the pressure in a brake reaction sensing chamber 30 to increase, which pressure is transmitted to a further inlet 33 of valve 24. A piston 34 is there - by held in the position shown in which a valve member 40 having grooves 46 permitting communication between two chambers 26, 42 uncovers a port 41, fluid passing through the port to rear brake actuator 29 by way of passage 47, a groove 45 in a shoulder 39b of piston 34 outlet 45 and pipe 27. When the wheel 21 starts to lock, fluid pressure in the chamber 30 is decreased causing a corresponding decrease in valve chamber 49, piston 34 then moving leftwardly to close port 41 and relieve the pressure in the rear brake cylinders 29. The limiter is also made responsive to load by the provision of a lever mechanism connected to the rear axle of the vehicle, the vertical rod 59a of which ever acts on a ball 59a to control the movement of piston 34. In a modification in which the front brakes are discs, the brake reaction is measured by means of load gauges 400 Fig. 5 (not shown) electrically connected through leads (150) to strain gauges 500 forming a Wheatstone bridge circuit Fig. 6 (not shown). When the wheel 21 starts to lock signals are passed to solenoids (700a) (700b) controlling movement of the piston 34. If the pressure in line 32 fails piston 50 will remain in the position shown to block movement of piston 34 so that the rear brake pressure is unmodified.

Patent GB-877632-A (GB)
Title: Improvements in and relating to epoxidation
Filed: 1959-12-08
Abstract: Ethylenically unsaturated compounds are epoxidized by reacting with a preformed percarboxylic acid having not more than 10 carbon atoms in the molecule in the presence of sufficient acid acceptor to neutralise 15% to 80% of the acid present in the reaction mixture. The reaction is effected at -10 DEG C. to +80 DEG C. for 1/2 to 8 hours and the peracid is employed in an amount sufficient to epoxidize all desired unsaturation.  Preferred starting materials are the 4 to 6 carbon aliphatic and cyclo-aliphatic olefines such as pentene and cyclohexene. Olefines which carry alkyl and aromatic hydrocarbon-substituents on carbons alpha to the unsaturation are exemplified by a -methyl styrene, limonene, a -pinene, myrcene, allooccimene, diisobutylene, camphene, polybutadiene, copolymers of butadiene with other unsaturated compounds, tripropylene and tetrapropylene.  The unsaturated compounds may also carry hydroxy, carboxyl, sulphonic acid, halogen or aldehyde groups. Thus the process may be used to form epoxides of fatty acid esters.  Typical acid acceptors are the alkali and alkaline earth metal hydroxides, carbonates, bicarbonates, acetates, propionates, butyrates, valerates, caproates, caprylates, pelargonates, phosphates, silicates and borates.  The preferred percarboxylic acids are performic, peracetic, percyclohexanoic, perpelargonic.
