Abstract: 832,707. Paper marked by pressure. UARCO Inc. April 15, 1957 [Aug. 3, 1956], No. 12209/57. Class 96. The surface of paper to be marked by pressure is covered with particles of darkcoloured matter, e.g. pitch from a petroleum base, magnetite, pyrolusite, chromic oxide, or cadmium red, each particle being coated with a pigment of light colour, e.g. titanium dioxide, optionally with a thin film of colourless wax between, to facilitate adhesion between the two pigments. The coated particles withstand ordinary handling but are crushed under the impacts of typing to expose the dark-coloured matter. As illustrated, dark particles P from an agitated bath 4 of wax solution are deposited on a conveyer 8 on which they are heated to 100 C. to drive off solvent from their wax coating. They pass through screens 10 to break up or remove agglomerates, and fall through a tower 11 containing titanium dioxide smoke, to a conveyer 15, through screens 16 and on to a travelling web of paper 27, particles not adhering being returned to the screen 16. In a modification, the two kinds of particles are intermingled and rolled together between a stationary and a rotating plate, heat being supplied to melt the wax coating.

Title: Improvements in or relating to variable-speed transmissions
Inventor: KELBEL DONALD W
IPC: F16H47/08
Filed: 1956-04-24
Abstract: 805,172. Change - speed gear. BORGWARNER CORPORATION. April 24, 1956 No. 12607/56. Class 80 (2). The percentage of input torque passing through a hydrodynamic torque-converter 16, combined with multi-ratio planetary trains 17, 18 for torque-splitting in some ratios, is 100 in first and reverse, 57 in second and 40 in direct-drive high. Both trains have intermeshed planets meshing a sun and ring gear. In first, a rear clutch 22 is engaged to connect the rear sun 47 through a sleeve 14 to the front planetcarrier 39, both these reaction members being then held by a brake 20. All the input torque passes from the engine shaft 10 through the torqueconverter 16 to the sun 35 of the front train 17, the ring 36 of which passes a reduced drive through an inner shaft 13 to the planet-carrier 51 of the rear train 18 which passes a further reduced drive from its ring 48 to a final output shaft 11. In second, the rear train 18 is kept in reduction by the brake 20, the rear clutch 22 is released and a front clutch 19 engaged to drive the front planet-carrier 39 mechanically by the input 10. At the coupling point of the torque converter, the front sun 35 is driven through the converter at substantially the same speed as the mechanically-driven planet-carrier 39, and the split torques combine at 1 to 1 in the front train, the ring 36 of which drives the rear train 18, still reducing as in first. In one-to-one third speed, the brake 20 is exchanged for the rear clutch 22, whereby the rear sun 47 receives a direct mechanical drive through the front clutch 19 and front carrier 39, whilst, above coupling- point, the rear carrier 51 is driven at substantially the same speed by the front ring 36. Torque combining occurs in both trains. In reverse, the rear clutch 22 is engaged together with a brake 21, the latter holding the connected rear carrier 51 and front ring 36. All the input torque passes through the torque-converter to the sun 35 of the front train, which reverses and reduces, the front carrier 39 driving the sun 47 of the rear train, which reduces only. The brakes and clutches are fluid-pressure operated.

Title: Gear Pumps
Inventor: WARNE EUGENE HAROLD
IPC: F04C2/08
Filed: 1966-03-23
Abstract: 1,170,773. Gear pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. March 8, 1967 [March 23, 1966], No.12801/66. Heading F1F. In a gear pump having a pair of externally meshing gears the teeth of both gears are asymmetrical and have involute operating faces. The asymmetry occurs due to relieving the teeth on their inoperative faces as compared with a symmetrical involute tooth. The inoperative faces extend uniformly throughout the axial lengths of the gears and may also be of involute shape. The relieved portions of the teeth prevents the build up of hydraulic pressure in the space between two pairs of successive meshing teeth and thus reduces tooth wear.

Abstract: 436,737. Organs. TAYLOR, J. I., and COMPTON ORGAN CO., Ltd., J., Chase Road, North Acton, London. April 30, 1934, No. 13029. [Class 88 (ii)] A stop - combination action for an organ comprises two sets of contacts in rows at right angles, the contacts in one set comprising pairs of notched members, and in the other consisting of upstanding springs, each upstanding spring coacting with either one of a pair of the notched contacts. Each row of notched contacts k<1>, k<2> corresponds to a stop and each cross-row of upstanding contacts b to a piston c allocated to a stop-combination. The combination is prepared by depressing the stop keys corresponding thereto, each key depressed energizing a "stop selector magnet" l drawing a bar k against the spring action of a pair of contacts m<1>, m<2> until the notched contacts k<2> are opposite the upstanding contacts b. To set the combination, the general " setter-piston " i and the manual piston c allocated to the combination are pressed, the piston i by a magnet h<1> lowering a multiple switch h so that current through the piston c may energize a " set piston magnet " f drawing a bar e with triangular apertures e<1> through which the upstanding contacts b pass, against the action of a spring g. On release of the pistons i, c the bar e carries the contacts b into notches k<2> of selected stops and into notches k<1> of stops not selected. To bring the combination on, the allocated piston c alone is pressed and, switch h being now in raised position, a multiple switch d is thus closed carrying current to the upstanding contacts b. A contact b in a notch k<2> (or kl) completes a circuit to the " on (or " off ") coil of a stop through contact m<1> (or m<2>), unless the stop is already " on (or " off ") in which case this circuit to the " on " (or " off ") magnet is already broken at m<1> (or m<2>) thus economizing current.
