Filed: 1924-03-12
Abstract: 213,246. British Thomson-Houston Co., Ltd., (Assignees of Garrett, B. A.). March 23, 1923, [Convention date]. Force-feed lubricating for gearing. A gearwheel pump drawing lubricant from a gear casing 10 and delivering it to the teeth of the gear wheels 5, 6 and to the bearings 9 of the wheel shafts 7, 8, is driven from one of the shafts and is located above the level of lubricant in the casing, means being provided whereby the pump is primed automatically when the gearing is started up. An extension 12 of the shaft 7 extends through a pump casing 13 secured to the end of the casing 10 and drives a gear pump 14 which delivers lubricant to the bearings and gear teeth through conduits 16, 19 and 20. The suction pipe 15 communicates with the casing 10 through a vertical conduit 17, a pipe 18 and a strainer 22. The .pump is primed when starting up from a reservoir 23 provided above the level of the pump and connected to the pipe 18 by conduits 24, 25. When the gearing is idle, the level of lubricant in the casing is such that the wheel 5 dips into it, so that when the gearing is started up the wheel 5 coacts with a curved' plate 29 to form a pump forcing lubricant into the reservoir 23, the lubricant being directed into the reservoir by a curved surface 27 formed in the cover 11 of the casing. A non-return wheel 28 in the pipe 18 prevents the return of lubricant from the pipe 17 to the casing. When the level in the pipe 17 reaches the pump, the latter commences to function, and the level of oil in the casing falls below the wheel 5.

Filed: 1959-02-27
Abstract: 876,558. Radio-wave reflectors. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Feb. 27, 1959 [Feb. 28, 1958], No. 6976/59. Class 40(7) Corner reflectors are formed from plane sheets of conductive material in which spaced parallel grooves or corrugations have been formed. The effect of the reflector is thus dependent on the polarization of incident energy. If the electric vector of the incident wave is substantially parallel to the grooves in the reflector then good reflection results whilst if the electric vector is perpendicular to the grooves little energy is reflected. The figure shows an embodiment consisting of three sheets 1, 2 and 3 in three planes defined by mutually perpendicular great circles of a sphere. The reflector surfaces may comprise panels fixed to a framework. The sheets 1 and 3 have corrugations arranged in planes which are parallel to sheet 2 while each section of sheet 2 has its corrugations at 45 degrees to the junction lines with sheets 1 and 3 as shown. Instead of a group of eight reflectors only one individual corner reflector may be constructed. The panels may have grooves machined in their surfaces instead of being corrugated. The reflector may be enclosed in a protective housing transparent to radio waves.

Filed: 1943-05-05
Abstract: 563,800. Toughening glass. PARFITT, A. W. (Temp-R-Lens Corporation). May 5, 1943, No. 7095. [Class 56] A method of toughening a lens, watch glass, or like article consists in heating the article almost to the softening temperature of the glass, and then chilling it by means of a solid conductor, or a jet of gas, applied at the centre point of a desired strain pattern in the glass. The chilling apparatus comprises an upright member 22, Fig. 4, provided with a pivoted arm 25 which carries at its outer end a carbon rod 27 having a rounded point 28 at its lower end. A second carbon rod 29 having a rounded point 30 is mounted below and in line with the rod 27, and the two parts are drawn together by a spring 33. In use, the heated lens 31 is supported in a horizontal position between the points 28 and 30, either by the pressure of the points or by a suitable carrier. The points' rapidly conduct heat away from the glass to form a strain pattern, shown in Fig. 2, which can be seen by examination with a polariscope. The carbon rods can be replaced by metal rods, but in this case small pads of asbestos are placed between the points -and the glass to 'prevent the glass from cracking. The pads can be dispensed with if the points are spaced a little distance from the glass. In another construction, the rods are replaced by metal tubes from which a fine jet of gas is directed against each surface of the glass.

Abstract: 247,760. Wenzel, J. E. March 17, 1925. Feeding webs.-In a device for drawing off fabric webs from drying machines wherein the web is carried in loops depending from rods b supported on rails b<1> and carried by endless chains, the web is drawn off intermittently by constantly driven friction rollers k, k<1> against the tension of a heavy roller c lowered into the loop of the web by a cord d. While the cord c is being lowered into the loop of fabric, the web is held by a brake o, carried by a weighted lever 120, cooperating with a smoothing rail i. Movement of the roller c is effected through the cord d by a chain 3 to a projecting pin q on which the cord is attached, the roller being raised as the pin q descends. Operation of the brake lever 120 is effected by a threearmed cam 11, against which a roller 13 on the lever is pressed by gravity, and a six-toothed star wheel 19 secured thereto, rotation of the cam being effected by the engagement of the pin q and a second pin p on the chain with the star wheel. Motion is imparted to the chain 3 through gearing from a motor 7, and from a wheel 8 on the shaft of the sprocket wheel 5 by a chain 9 to a guide roller g, and from thence by a third chain to the roller k from which the roller k<1> is driven by gearing. In operation, with the roller c supported in its housing d<1> and the pin q having just passed round the sprocket wheel 6, the loop B, or loops of two webs side by side, being dealt with is moved underneath the roller and, as the pin q rises, the roller c is lowered into the loop, the star wheel and cam having been moved by the pin p to bring the brake into position to prevent the feed of the web. While the pin q is passing over the top of the wheel 5, the roller c draws the two webs into alignment and in its downward movement, after passing over the sprocket wheel 5, the pin q rotates the star wheel 19 to cause the cam 11 to lift the brake and allow the rollers k, k<1> to draw off the web as the roller c is raised. A second smoothing rail h, concentric with the pivot, 12 of the lever 120, is provided. The pull applied by the rollers k, k<1> may be altered by making the roller k<1> adjustable round the roller k.
