Title: Improvements in or relating to Hydraulic Speed Varying Devices.
IPC: F16H61/40
Filed: 1915-01-04
Granted: 1915-12-09
Abstract: 13,620. Selas Co., and Turner, E. Jan. 4, 1915. Safety-vadves. - Relates to valves for controlling the by - pass passage between the pump and motor of an hydraulic transmission gear. The pipes a<1>, a<2> are connected to the pump and motor, and the pipe a<3> connects the pressure and suction sides of the pump so as to by-pass part of the delivery. A piston d slides on the rod b<1> of the valve b, and is adapted to be lifted against the spring h by a pre-determined pressure. When the piston reaches the collar h on the valve spindle, the valve is lifted. The load on the piston d may be adjusted by the collar g through which the valve rod slides, while the valve may be permanently held open to any required extent by adjusting the nut f, thus allowing a part of the liquid to be by-passed under all pressures, and determining the maximum speed of the motor. In a modification, the piston d is rigidly attached to the valve rod.

Title: Improvements in Means for Measuring and Regulating Temperature Differences.
Inventor: WILSON JOHN CROSIER

Granted: 1915-08-10
Abstract: 18,495. Wilson, J. C., and Packard, H. N. Aug. 16, 1913, [Convention date]. Thermometers and pyrometers; anemometers. -In apparatus particularly applicable to steam, gas, and like meters, such as are described in Specification 30,405/09, for measuring the difference in temperature between two given points, or maintaining a predetermined difference in temperature between such points, by means of the changes in electric resistance due to temperature changes, one or both of the resistances is formed of substances so selected both as to nature and quantity that through a wide range of temperature a certain difference in resistance always corresponds to a fixed temperature difference. In the gas-meter shown, the gas flows through a conduit 1 and is heated by a resistance 2, its temperature before and after heating affecting resistance thermometers 3, 4, of equal resistance at equal temperatures, arranged in two adjacent arms of a wheatstone bridge, which is adapted to be initially balanced by an adjustable resistance 10. A constant temperature difference between the thermometers 3, 4 is automatically maintained by means of a rheostat 7 adapted to be controlled by suitable means from the wheatstone bridge to vary the heating-current, which is measured by a watt-meter, whereby the flow of gas is also measured. When the gas is being heated, the difference in the resistances of the thermometers 3, 4, which are preferably formed of nickel wire, is balanced by a resistance 11, which is formed, for example, of nickel and manganese so proportioned as to compensate for the differences in the temperature-resistance coefficient of the nickel thermometers at different temperatures. Variations in the specific heat and moisture content of the gas may be similarly compensated.

Inventor: GENTER ALBERT LEGRAND
IPC: B01D29/84
Filed: 1915-01-26
Abstract: 1302. Genter, A. L. Jan. 26. Filter presses; filters with vertical filtering- partitions; bag filters.-In cake-forming filters operated under pressure, the cakes are compressed by a solid or porous plate D, Fig. 1, arranged at a suitable distance from the filtering-partition B and so supported that, when the cake has attained such a thickness that it contacts with the plate D, the resulting disturbances of the hydraulic equilibrium causes the plate D to move automatically in the direction of the filter partition B and compress the cake. The rod d on which the plate D is mounted is fitted with a pointer f to indicate the thickness of the cake. When the plate D is porous, the cake may be washed and afterwards treated with steam or compressed air. In the form of apparatus shown in Fig. 3, a series of sliding filter plates E are provided, which successively act as pressure plates as the successive cakes are formed. In filters comprising filter plates suspended within a common pressure vessel, the press-plates are arranged on guides between the filter plates, or the filter plates may be arranged to act as press-plates. The arrangement may be modified so as to act simply as an indicator of the thickness of the press-cake.

Abstract: 3871. Stanbridge, H. March 11. Drilling; drills.-Relates to the manufacture of centrifugal safety-shutters for percussion fuses of projectiles, in which the shutter is controlled by a spring, one end of which is disposed within a recess in the shutter and is covered by a guard. According to this invention, the guard a<3>, Fig. 3, instead of being separately formed and attached at a<6> by soldering &c., is left as an integral part of the shutter by suitably cutting away the metal to form the recess. In one method, the metal is first cut partly through to such a depth as to leave the required thickness of metal for the guard a<3>. This may be done by using a cutter B, Fig. 4, having a stop b<1> thereon, in conjunction with jigs such as that shown in Fig. G, comprising a plate having a hole c<1> therethrough, and pins c<2>, c<3> to hold the shutter in position. Or the cutting may be done by profile milling. Finally, the portion a<5>, shown shaded in Fig. 3, is punched out.

Granted: 1915-11-18
Abstract: 9662. Martin, E. July 10, 1914, [Convention date]. Alkali aluminates; alumina.-Alkali aluminates are obtained by heating aluminous earth, such as bauxite, with calcium carbonate and a small proportion of an alkali salt, such as sodium sulphate, double aluminates being first obtained, which are decomposed on subsequent washing with sodium carbonate solution. The proportion of calcium carbonate should be enough to combine with the alumina and also with the impurities. The product is leached, preferably in two stages, with sodium carbonate solution, sodium aluminate being obtained, which is treated by auto-precipitation or carbonation, or both, to obtain the alumina. To avoid solution of the silica, the sodium carbonate is used in the ratio Al2O3 : Na2O=1: 10, the concentration being 75-100 grm. Na2CO3 per litre.

Title: Optical diffusing plate and display device
Inventor: AGANO TOSHITAKA
IPC: G02F1/13357
Filed: 2000-01-18
Abstract: PROBLEM TO BE SOLVED: To obtain satisfactory light-diffusing performance and a good contrast ratio by forming a passing region, where incident collimated light mainly passes and a non-passing region having relatively low light-transmission property and applying the both materials for these regions at a time. SOLUTION: An optical diffusion plate 16a is produced by fixing light- transmitting spheres (beads) 20, which constitute a diffusing layer with a light- absorbing binder 22 to a light-transmission supporting sheet 18. The collimated light emitted from a backlight part and passing a liquid crystal panel 12 to carry an image is refracted (diffused) by the spheric beads 20, passes through the contact area between the beads 20 and the supporting sheet 18 and near this area (contact part) which is the passing region for light, and is diffused sufficiently. Since a binder 22 has light-absorbing property, the non-passing region except for the contact part of the beads 20 and the supporting sheet 18 acts as a black mask. Thus, the external light from the observer's side is not reflected or diffused by the optical diffusion plate 16, and there is no decrease in contrast.
