Title: Improvements applicable to suspension bridges
IPC: E01D11/02
Filed: 1934-04-05
Abstract: 414,619. Bridges. BATICLE, L. U. E. A., 32, Avenue Kleber, Paris. April 5, 1934, No. 10367. Convention date, April 5, 1933. Addition to 364,524. [Class 20 (i).] A modification of the invention described in the parent Specification comprises the use of a connector between the points of the suspension cable to be rendered fixed and between these points and the end pillars, these connectors always remaining in tension. Fig. 1 shows the arrangement according to a modification described in the parent Specification, and Fig. 2 the modification according to the present invention, in which the diagonal connectors b, H, b<1>, H<1> are dispensed with, the points H, H<1> of the cable being fixed by the horizontal connectors C, H, C<1>, H<1> to the pillars. A supplementary suspension cable may be used to maintain the connector cable horizontal or further support cables h, Fig. 4, from the pillars to the connector cable are used for this purpose. For rendering multiple points on the cable fixed inclined support cables b,H, b, H <1>, Fig. 6, may be used at each end and the points on the cable are interconnected by horizontal and diagonal support cables. The points on the cable may not necessarily be connected by horizontal cables, but in the case in which the supports are on different levels by connectors parallel to the line joining the supports. When the suspension cable is used to support electric traction lines, the feeder for the lines may be used as the support cable for rendering the points of the suspension cable fixed.

Title: Shadow thermoprinting
IPC: B41M5/26
Filed: 1957-03-29
Abstract: 863,366. Photothermographic processes. MINNESOTA MINING & MANUFACTURING CO. March 29, 1957 [April 2, 1956], No. 10377/57. Drawings to Specification. Class 98(2) A graphic original is copied on to a heatsensitive copy sheet which is absorbent of radiant energy by placing the original on top of the heat-sensitive copy sheet and irradiating it with radiant energy to provide a transmitted radiant energy pattern which is absorbed by the copy sheet to give a visible image. The opaque parts of the original absorb the radiant energy and do not conduct it to the copy sheet, but it may be desirable to place an additional barrier such as silk bolting cloth between the original and copy sheet to prevent such conduction. The heat-sensitive layer may comprise ferric stearate and gallic acid in an ethyl cellulose binder, preferably together with pigments such as titanium dioxide or carbon black, or it.may comprise gum guaiac and cerium stearate in an ethyl cellulose binder together with pigmerits as desired. Alternatively, the copy paper may comprise a dark or coloured substrata obscured with a layer of normally transparent fusible material e.g. a waxy material, as is described in Specification 673,244.
Patent GB-233334-A (GB)
Title: Improvements in or relating to processes of purifying oil
IPC: C10M175/00
Filed: 1925-04-21
Abstract: Oil that contains sludge and emulsion-forming or sludge-forming substances, e.g. oil that has passed through bearings and is contaminated by products of decomposition, is mixed with such a quantity of water having such a temperature that the mixture will be at a temperature low enough to precipitate sufficient of the contaminating material to leave the oil at a proper degree of purity. Other contaminating substances are dissolved in the water.  The contaminating substances and the wash water are removed by passing the mixture through a centrifugal machine.  The water may be mixed with the contaminated oil either before or after the latter has been introduced into the machine, and additional water may be added after the mixture is in the machine.  The oil may be separated from the water in two stages, the moist oil from the first stage being heated before the second centrifuge.  Hot water may be introduced into the centrifugal separator to heat the oil that has been freed of solid particles.

Abstract: 549,033. Aircraft planes and fuselages. VICKERS-ARMSTRONGS, Ltd., and WALLIS, B. N. Aug- 25, 1941, No. 10819. [Class 4] For jointing the plating of a stressed skin aircraft structure, such as a wing, along the line of junction to an adjacent section, such as a wing root, so that the tensile and shear stresses in the plating of one section may be transmitted directly to the plating of an adjoining section, a series of spaced anchorage members is directly attached to the inner side of the skin plating of each section, the anchorage members being diposed in pairs on opposite sides of the joint and connected together by bolting means accessible from outside the structure, the outer face of the skin remaining unobstructed. Each anchorage member comprises a sole plate 92, riveted to the skin, bosses 92, and quarter-spherical members strengthened by ribs 9, 93. The ribs 93 of opposite members are machined to meet along the joint and the quarter spherical members are spigoted at 96 to transmit shear stresses. A right and left hand screwed pin 10 engages screwed holes in the bosses 92 to draw the parts together, holes being cut in the plating opposite the hemispherical recesses formed by the meeting members to enable the pin to be turned. A cover plate 13 secured by a clip 14 engaging the pin may close the opening or it; may be secured by a grub screw 15 which also locks the pin 10 against rotation.
