Patent GB-832535-A (GB)
Title: Improvements in methods of coating cathode-ray tubes with luminescent material
IPC: H01J9/227
Filed: 1957-01-10
Abstract: A homogeneous luminescent layer is formed on the screen of a cathode-ray tube by a photographic process.  A mixture of luminescent material and photo-sensitive binder is coated, e.g. by a sedimentation process, on the screen and exposed uniformly to ordinary light or ultra-violet to fix the binder.  Excess binder is then washed off.  By controlling the strength or time of exposure the final thickness of the layer can be determined.  The binder may be polyvinyl alcohol sensitized with potassium bichromate.  Another suitable binder is glue or gum arabic.  The luminescent coating may be dried after being formed and before exposure to light.

Title: Improvements in two-stroke internal combustion engines and in particular to the exhaust systems thereof
IPC: F02B25/00
Filed: 1936-01-11
Abstract: 473,686. Two-stroke engines. KADENACY, M., and ARMSTRONG WHITWORTH SECURITIES CO., Ltd. Jan. 11, 1936, No. 1018. Drawings to Specification. [Class 7 (ii)] In an engine in which the timing of the inlet and exhaust port is such that the burnt gases, discharged as a mass, induce a fresh charge into the cylinder, the conditions of discharge are so arranged that, over a range of speeds, the suction commences at the opening of the inlet ports. In particular examples, the rate of opening of the exhaust ports increases or decreases during the cycle, according to whether the exhaust lead is constant in crankangle or in time absolute. Similar diagrams, and deductions, to those in Specification 473,684, enable the best arrangement of discharge conditions to be arrived at, the method of their use being set out at great length. The exhaust arrangements described in any of the Specifications referred to therein, or in Specification 431,856 or 433,502 may be used. If the exhaust occurs over a constant time interval, inlet valves which open for a constant lapse of time must be used-e.g. slide valves loaded by springs, electromagnets or by hydraulic or gas pressure. The arrangements for an engine receiving a pre-compressed charge are discussed. Specifications 431,857, 447,537, 448,526, 451,765, 451,928, [Group XIX], 473,267 and 473,687 also are referred to.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/54
Filed: 1919-01-16
Abstract: 141,785. Cloud, J. W. Jan. 16, 1919. Fluid-pressure. - Relates to valve mechanism of the kind described in Specification 120,652 for effecting the graduated release of the brakes and comprising a brake-cylinder exhaust valve controlled by train-pipe and brake-cylinder pressure in opposition to constant reservoir pressure. According to the invention, two separate diaphragms, subject respectively to the constant reservoir pressure and to the train-pipe pressure, together with a spring, are provided, these diaphragms being coupled by a lever to the combined abutment and valve controlling the brake-cylinder pressures. As shown in Fig. 1, a pair of diaphragms 10, 12 are connected by a stem 11 pivoted at 17 to a lever 16 turning about a fixed pivot 16<1>. The diaphragm 12 is constantly subject to train-pipe pressure admitted at 5 and to the pressure of a spring 13. The diaphragm 10 is subject to the pressure in a reservoir 1 also connected to the train-pipe or to the auxiliary reservoir at 8, but through a non-return valve 9. The space between the diaphragms is open to atmosphere. The lever 16 is also connected to a plunger 19 sliding in a chamber 6 connected at 7 to the brake-cylinder exhaust port of the triple valve. Ports 22 in the chamber 6, leading to a passage 21 open to atmosphere, are normally uncovered by the plunger 19. When the brakes are applied, the pressure in the reservoir 1 is unaffected and therefore moves the diaphragms 10, 12 against the reduced train-pipe pressure in the chamber 4, the ports 22 being thereby covered by the plunger 19. When the train-pipe pressure is raised to effect the partial release of the brakes, the brake-cylinder pressure, admitted to the chamber 6 by the triple valve, acting on the plunger 19, together with the train-pipe and spring pressure acting on the diaphragm 13, overcomes the constant pressure in the reservoir 1, and the exhaust ports 22 are uncovered until the brake-cylinder pressure has fallen sufficiently for the pressure in reservoir 1 again to return the plunger 19. The ball valve 9 may be arranged in a spring-pressed valve 27, Fig. 2, adapted to permit a limited return of air from the reservoir 1, and so prevent the pressure in this reservoir from exceeding by more than 20 to 30 lb., the pressure in the train-pipe or auxiliary reservoir when it has been reduced in applying the brakes.

A remote control lever 1 for a change-speed gear A is pivoted at 3 on a rotatable tube 4, so that, by swinging in one plane, about pivot 3, it moves endwise a rod 17 within the tube whereby, through rack-and-pinion gearing 21, lever 34, link 36, lever 38, and rack-and-pinion gearing 24, a shaft 11 carrying a.gear striker arm 12 is moved axially, while by swinging the lever 1 in a plane at right-angles, the tube 4 is rotated, whereby, through lever 40, link 44 and lever 10 the shaft 11 is turned. The tube 4 and rod 17 are supported by a slotted housing 46 having a polygonal part 52 secured by screws 50 in a polygonal recess in a fixing bracket 48, so that the angular position of the housing 46 may be changed. Alternatively, the rack-and-pinion gears 21, 24 may be connected by a flexible shaft, Fig. 1 (not shown), while the tube 4 may rotate, through bevel gearing, a second tube having a lever linked to the lever 10.

Abstract: 926,257. Fluid-pressure servomotor systems. DAVID BROWN TRACTORS Ltd. Jan. 16, 1962, No. 1633/62. Class 135. [Also in Group XXXI] A tractor power-lift mechanism comprises a variable displacement pump 10 for supplying pressure fluid to an hydraulic cylinder 11 containing a ram 12 which operates the rockshaft 14 of a lift linkage and a balance lever 16 which can be moved by the rod 23 either by movement of a manual lever 29 or by movement of a draft responsive link 27 secured to the upper link of the tractor lift linkage to operate the pump. Upon movement of rod 23 the lever 16 pivots about lug 17 on the rockshaft to move the pump 10 about its pivot 20, whereby pressure fluid is supplied to the cylinder 11 until the pump is returned to the zero displacement position by the lever 16 being moved by the lug 17 on the rockshaft about the pivot 21.
