Abstract: 1402363 Antiskid braking systems; valves AISIN SEIKI KK 21 Feb 1973 [25 Feb 1972 6 March 1972] 8411/73 Headings F2F and F2V In a vehicle antiskid braking system in which pressure is transmitted by a fluid pressure operated master cylinder 311, skidding is relieved upon detection of a skid condition by returning the pressure fluid used to operate the master cylinder to a reservoir 352. As shown, during normal braking a power piston 308 operates master cylinder 311 by fluid transmitted to a booster chamber 331 of a control valve unit on depression of a pedal 305 which causes rightward movement of a piston 304. A seat 317 of piston 304 engages a valve face 321 of a valve member 320 thereby closing the communication which normally exists between chamber 331 and reservoir 352 by way of a bore 354 provided in a piston 307, a blind bore 316, axial and radial bores 315, 314 in piston 304, chamber 330 and line 353. Thereafter, valve member 320 moves rightwardly to unseat a face 322 thereof from a seat 324 and establish communication between chamber 331 and an accumulator Acc. by way of a compartment 326, groove 328, path 349, grooves 337, 339, respectively provided in a valve member 335 and bore 336, and line 355. On detection of skidding a solenoid coil 344 is energized drawing valve member 335 rightwardly closing communication between path 349 and line 355 and intercommunicating a groove 338 in valve member 350, and path 350. Fluid in the chamber 331 is then returned to reservoir 352 by way of path 350 and groove 338, a radial bore 346, an axial bore 345 and a radial bore 347 respectively provided in valve member 335, annular groove 341 and line 353. If the accummulator or pump P supplying it fails, a mechanical connection is established from pedal 105 through piston 304, piston 307, and a projection 332 on piston 308 to apply the master cylinder directly. In a further embodiment two solenoid operated valves are provided controlling two valve members, one solenoid coil of which remains energized on brake release for a short while under the control of a capacitor so that rapid repressurization of the booster chamber is possible.

Filed: 1962-03-09
Abstract: 987,634. Colour photography involving masking. AGFA A.G. March 9, 1962 [March 14, 1961], No. 9204/62. Heading G2C. A light-sensitive photographic material comprises two silver halide emulsion layers on a transparent support, one of said layers being sensitive to the blue and red region and containing a mixture of two colour couplers which react with the oxidized developer to give a blue-violet dye image and the other layer being sensitive to the red and green region and containing a mixture of two colour couplers which react with the oxidized developer to give a greenish-yellow dye image. The term "blue-violet" means transparent to the blue region and "greenish-yellow" transparent to the green and red regions, but predominantly the green. To reduce the sensitivity to blue, a yellow filter layer may be incorporated or dyes may be added to the emulsion layers. The emulsion layers may be coated on opposite sides of the support. In the examples a polycarbonate support is coated on one side with a yellow filter layer of colloidal silver in gelatin and then with a redsensitized silver bromide gelatin layer containing tartrasise and a magenta and a cyan coupler. The other side of the support is coated with a red and green sensitized silver bromide emulsion containing a cyan coupler and a yellow coupler. After exposure to a multi-coloured original and development, a complete mask is obtained for use in colour separation records. These records are produced by registering the mask with the original and exposing through the appropriate colour separation filters. Specification 811,311 is referred to.
