Abstract: 1,218,680. Change-speed control. FORD MOTOR CO. Ltd. 21 April, 1969 [13 May, 1968], No. 20191/69. Heading F2D. A centrifugal governor valve 70, mounted radially on the output shaft of an automatic transmission on a motor-vehicle, and providing governor signal pressure 88 for controlling ratio-shift valves in conjunction with TV pressure regulated by engine inlet-manifold depression, comprises a primary mass 82, radially slidable outwards under centrifugal force in opposition to a spring 98 to throttle a port 92 leading to exhaust 96, thereby producing speed-responsive back-pressure in a governor feed line 88, fed from an input-driven pump and control line 120 through a feed-valve 110, designed to maintain a constant pressuredifferential across a restrictor 132 between the feed valve 110 and governor line 88. This prevents loss of pressure in the pump-fed control line 120 at low speeds when the governor port 92 is open to exhaust and provides a more precise control of governor pressure at those speeds. The governor feed-valve 110 comprises a valve-spool with a land 116 metering to an outlet 122 under rightward loading by a spring and governor pressure 88 acting through a restrictor 130, and leftward loading by feed pressure on the upstream side of the restrictor 132. The governor pressure characteristic at high speed is modified by a secondary ball-mass 84, outwardly loaded by a spring and centrifugal force, which, at high governor pressures are overcome by inward loading by governor pressure 88 to open a port 104 to exhaust 108. The transmission, Fig. 1 (not shown), is the usual torque-converter-driven three-speeds and reverse Simpson planetary gear-set.

Title: Improvements in or relating to photographic reproduction processes
Inventor: AXFORD ANTHONY JOSEPH
IPC: G03C8/06
Filed: 1959-06-12
Abstract: 878,064. Photographic diffusion transfer materials and processes. ILFORD Ltd. June 1, 1960 [June 12, 1959; July 20,1959], Nos. 20284/59 and 24878/59. Class 98(2) The material comprises a transparent film support, a reception layer containing nuclei, a white pigmented colloid layer or alternatively the presence of pigment in the reception layer, and a thin layer of gelatino silver halide emulsion. Exposure from the emulsion side and processing in the presence of a silver halide solvent as by immersion or application of developer solely to the emulsion surface, provides a positive image in the reception layer which can be viewed through the support against the background of the pigment. Preferably a neutralizing material such as acid phosphate is included in the reception layer, and the layer sequence has the advantage that such substance is inoperative until the developer penetrates the emulsion. Numerous further features and modifications include use of a viscous developer, retention of such on the emulsion by the presence of a further sheet which may or may not be removed, use of an outer, light-insensitive emulsion layer to provide a reservoir of silver halide and increase intensity of the positive image, and the incorporation of antihalation substances. A specific example of material and developer is provided. Specifications 614,155, 654,631, 746,948, 751,955 and 875,644 are referred to.

Title: Improvements relating to drum-type electrical controllers
IPC: G05G5/04
Filed: 1935-07-17
Abstract: 452,951. Controllers. SCARF, C. T., 58, Hale Road, Hale, Cheshire, LAST, C. H., 101, Wilmslow Road, Rusholme, Manchester, and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd., 1, Kingsway, London. July 17, 1935, No. 20392. [Class 38 (iii)] In a controller of the kind in which a rotary member or drum is arranged to be rotated in both directions from its " off position to which it is biassed, a member 7 is adapted to be given, as the result of movement of the drum under its biassing means, a sudden movement against a biassing device 13 so as to be brought into the path of movement of the drum or a member 4 secured thereto and to romain by virtue of its inertia in the said path of movement sufficiently long to intercept the drum or the member 4 and arrest it in the " off position. The controller has the usual star-wheel 1 and cooperating lever 2, and secured to the drum shaft is a disc 4 with a radially-sided notch 5 and a projection 6, the circumferential width of the projection 6 is considerably less than that of the notch 5. A bell-crank lever 7, pivoted at 8, has a hooked arm 10 which engages the notch 5 in the off position of the drum, and a roller 14 biassed by a spring 13 to engage the edge of the disc 4, the projection 6 engaging the roller 14 in the off position of the drum, the length of the hook 11 is smaller than the depth of the notch 5. When the drum is released from an operative position it moves to its " off " position and the projection 6 strikes the roller 14 to rotate the lever 7 and cause the hook 11 to move into the notch 5. If the drum is moving so quickly as to be liable to overshoot the " off " position the lever 7, due to its inertia, does not move back quickly enough to lift its hook 11 clear of the notch 5, and the drum is prevented from moving too far. With a slow movement of the drum through its '' off " position the movement of the lever 7 follows the shape of the disc 4 and the hook 11 will move back to clear the notch 5.
