Title: Control valve, particularly for hydraulic braking systems
IPC: B60T8/26
Filed: 1966-09-15
Abstract: 1,134,809. Hydraulic brakes. WAGNER ELECTRIC CORP. 15 Sept., 1966 [28 Sept., 1965], No. 41216/66. Heading F2F. In a control valve for insertion in the brake line 13 leading to the rear wheel brakes 18, 19 of an hydraulic braking system for a vehicle, a piston 29 having opposed differential areas is urged by a spring 35 against an end cap 24 of the valve and a valve means 42 is provided within the piston 29 and is normally held open by means of a spring 49 to leave the passage leading to the rear wheel brakes open. In operation, when the brake master cylinder 3 is actuated, fluid under pressure is supplied directly to the front wheel brakes 11,12 via conduits 6, 7 and 8 and at the same time fluid under pressure is supplied via an inlet port in the valve 5 through radial passages 40, axial recess 47 and axial grooves 48 past the open valve seal 46 to the outlet port 26 leading to the rear wheel brakes. The displaced fluid pressure acts on the effective area A3 and also acts on the effective area A4 and since the effective area A3 is predeterminantly greater than the effective area A4 the piston member 28 is moved rightwardly towards a stored energy position where the spring 35 is compressed. The displaced fluid pressure also acts on the effective area A1 to urge the valve member 41 rightwardly in opposition to the force of the spring 49, such that, when the displaced fluid pressure reaches a predetermined value, the valve 42 is closed to interrupt the pressure fluid communication through the passages 40, 47 and 48 between the inlet and outlet ports 25 and 26 of the control valve 5. The interruption of the pressure flow through the passages means that the effective areas A1 and A3 are additive to create an effective area A2 as the input pressure is increased above a predetermined value the piston member 28 is urged leftwardly and the spring 35 releases the stored energy to increase the output fluid pressure in a predetermined ratio. By this means the front wheel brake assemblies 11, 12 are capable of applying a greater braking force than the rear wheel brake assemblies 18, 19 to compensate for transfer of weight towards the front of the vehicle during a brake application. When the applied force is removed from the brake pedal 2, fluid is returned to the master cylinder 3 and the valve member 41 and the piston member 28 are moved rightwardly to diminish the output fluid pressure in the line 13 and to load the spring 35. When the fluid pressure in the rear wheel brake line 13 reaches a certain predetermined low value the force of the spring 49 urges the valve member 41 leftwardly to its original open position to effect release of the rear wheel brakes.

A mixing valve for controlling the temperature of water fed to two heating circuits comprises a double-headed valve member 4, controlling two coaxial inlets 2, 3, one of which leads from the boiler and the other from a return pipe of the heating circuit. The valve 4 is mounted for rotation on a spindle 7 and a bi-metal coil spring 9 is secured at one end to a sleeve 6 of the valve and at its other end to a temperature-setting finger 10. The valve housing 1 is provided with two outlets 11, 12, leading to the heating circuits, which are controlled by a rotatable valve member 13 secured to the spindle 7. The valve 13 has two openings 14, 15 such that both outlets may be opened at the same time or either one may be closed while the other is open. The spindle 7 may be turned manually or may be actuated by a solenoid. In a modification the valve 13 is provided with three openings such that for each 90 degrees rotation of the valve the outlets are both open, one open, both open and the other open respectively. In this case the rotation of the spindle is conveniently operated by a solenoid through a time control switch, the spindle carrying a ratchet wheel actuated by a pawl on the armature of the solenoid.

Title: A process for the resolution of racemic homocysteic acids
IPC: C07C/
Filed: 1962-11-07
Abstract: DL-Homocysteic acid or the monoammonium last thereof is optically resolved by making and maintaining a supersaturated aqueous solution of the racemate or of the racemate and a small amount of optically active isomer, crystallizing an optically active isomer from the solution in the presence of crystals of optically active isomer and separating the crystals from the solution.  After the crystals have been separated from the solution, more racemate or the other isomer is added thereto and this other isomer is then crystallized out and separated from the solution.  Pure optically active homocysteic acid or the monoammonium salt thereof is obtained by dissolving optically active homocysteic acid which is contaminated with racemic acid in sufficient water, aqueous mineral acid, aqueous alkali or mixed solvent of water and a water-soluble organic solvent to dissolve the racemic component completely to form a solution which is at least substantially saturated with respect to the racemic component, and separating the optically active component remaining as a solid phase from the liquid phase.

A jig washer 1 has an extraction chamber 5 for heavy products moving off the end of a perforated material bed support, e.g. a screen 2, and the chamber 5 has a bottom wall 10, which supports the material in the chamber, and a discharge opening 11, .for the heavy products, with a discharge sill 13 to afford support to material spilling through the discharge opening, the sill being adjustably inclined to alter the rate of discharge of the heavy products. Raw coal enters the jig at 4 on to the screen 2 where it is subjected to liquid pulsations from air chambers 3 under the screen. The raw coal separates into a bottom layer of shale and a top layer of coal and middlings. The shale enters the chamber 5 and spills from the discharge opening 11 to form a natural slope 14 on the sill 13 without passing over the sill. The sill 13 is preferably perforated and on each upward pulse causes the slope 14 to be slightly lifted, so that some shale spills over the sill and more shale enters the chamber 5 to take its place. The sill 13 is hinged to the bottom wall 10 and its inclination may be automatically controlled by a float 16 and servo-mechanism 17. The coal and middlings pass over a wall 7 and are separated on a further screen 2<SP>1</SP>, the coal leaving via a trough 18 and the middlings being extracted in a chamber 5<SP>1</SP> similar to that described. The shale and middlings settle in the jig and are removed by a bucket elevator 15.
