Title: Improvements in pressure-tight cabins for aircraft
IPC: B64D13/04
Filed: 1941-04-08
Abstract: 565,860. Aircraft pressure cabins. VICKERS - ARMSTRONGS, Ltd., and WALLIS, B. N. April 8, 1941, Nos. 4701/41 and 2234/42. [Class 4] A pressure cabin for aircraft comprises an air-tight inner wall or membrane supported against the structural members, an outer fabric or other envelope, the space between the envelope and inner wall being packed with heat insulating material, and an inner lining of puncture sealing material upon the inner wall or membrane. A fuselage is shown having longerons 2 and geodetic bracing 3 similar to that described in Specifications 388,438, 452,726 and 494,233, the framing being enclosed by an outer fabric envelope 4. The inner wall 5 consists of fabric woven from warps of hightensile steel, e.g. of 375 w.g. with textile weft threads with the steel warps disposed circumferentially to resist the pressure within the cabin. Alternatively, the steel warps may be disposed longitudinally and the hoop stress taken by the circumferential frame members. The wall 5 is rendered air-tight by a thin coating of latex and the coated wall made selfsealing by securing sheets of cellular rubber 6 on the inner face with rubber solution. The spaces surrounding the members 2, 3 between the envelope and inner wall are packed with wool noils. In another form, an all-textile fabric may be used for the inner wall 5 which is supported at intervals by circumferential wires passing through cleats at the nodal points of the geodetic bracing.

Filed: 1948-08-18
Abstract: 651,421. Curving. EUMUCO (ENGLAND), Ltd. Aug. 18, 1948, No. 4813. [Class 83 (iv)] In a reciprocating machine for bending plates up to 4 inches thick and 60 feet long the bending block is made lower on one side to permit a long work-piece to be bent without raising the unbent portion from the work support. A bending tool 16 is reciprocated by a fluid cylinder 15 coupled to a cross-head 17. The workpiece is supported on a bevelled bar 23 adjustable for varying the curvature of the bead by a plurality of screw gears from a common shaft 29 driven by an electromotor and a support 20 at a lower level than the bar 23 and fitted with wearing faces 21, 22 and a ramp 140. The work-piece is fed intermittently by a pusher 34 operated by a fluid cylinder 35 over a table 33 with hinged resilient support 134 and fluidpressure support 133. When the work-piece is bent to half-cylindrical form it is moved by a pusher 40 operated by a fluid cylinder 41 on to the table 33 reversed by hand and fed in again by the pusher 34 to complete bending to shape 60, Fig. 1. Hooks 42 and chains 43 may be released to the pushers to assist the feed. Rollers 50, 51 guide the plate edges.

Abstract: 443,397. Free - wheel mechanism for cycles. NAAMLOOZE VENNOOTSCHAP METAAL INDUSTRIE IMCO, Hengelo, Holland. Feb. 15, 1935, No. 4912. Convention date, April 28, 1934. [Class 136 (ii)] A bicycle &c. having front and/or rear wheel brakes actuated by back-pedalling, e.g. through cables and cams, is provided with a free-wheel device which is attached to the rear wheel and in which the driving-connection from the sprocket is effected by a number of balls or rollers mounted in a cage co-operating, through a deformable friction element, with the axle or other fixed part, whereby the driving- connection is held inoperative when the cycle is wheeled backwards. The clutch rollers or balls 3, adapted on forward driving to be gripped between inclined surfaces 2 and a ring 4 screwed on the wheel hub, are mounted in a cage formed of two parallel flat rings 5 secured together by pins 6, and to this cage is fixed, e.g. by means of a strip member 8, a friction spring 7, which is formed of a bent strip adapted to engage the axle cone or other fixed part in such a way that on forward rotation of the wheel it affords little or no frictional resistance, while on backward rotation it grips the cone &c. and holds the cage stationary, thus preventing the jamming of the rollers or balls.

Filed: 1961-02-13
Abstract: 949,397. Machine tool details. F. A. OHLINGER, and F. T. SHEPPARD. Feb. 13, 1961, No. 5326/61. Headings B3B, B3C, B3K and B3N. A work-holder comprises means 39 for rotating a table 21 and removable means 58, 75 for causing axial movement simultaneously with the rotary movement of the table. The graduated table is rotated by a handle 56 driving through the worm 38 journalled in an eccentric sleeve 43 which can be moved angularly by a thumb lever to disengage the worm from the wormwheel 30 keyed to the table spindle 19. The table can be clamped against movement by a split ring 84 clamped by a nut rotated by a handle 89. The spindle 19 is connected by a flat key 62 to the threaded sleeve 58 engaging the threaded spigot 75. The sleeve and the spigot cause axial movement of the table for threading or boring operations. By first detaching the plug 58, the threaded parts can be replaced by parts having a thread of different pitch, or removed to allow rotation of the table without axial movement.

Abstract: 686,846. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 3, 1950 [March 7, 1949], No. 5449/50. Class 39(i) An electron optical image converter tube has an apertured spherical anode cap and a concave photoelectric cathode bordered by contiguous with and electrically connected to a conductive zone also concave to the anode, the radius of the cap being not greater than the difference between the radius of the cathode and the shortest distance between anode and cathode. The spherical part 2 of a glass vessel 1 is coated internally with a thin translucent conductive coating 3, e.g. of silver, obtained by sputtering or electric deposition and connected externally through a vacuum tight seal. On this layer is formed a photo-electric cathode 5 comprising a mixture of silver and caesium oxide particles on which a thin layer of caesium is absorbed. At the other end of the vessel 1 is a reentrant part 6 closed by a flat plate 7 carrying a fluorescent screen 8 or a thin transparent conductive layer connected by metallisation to the anode. A cylindrical metal tube 9 with an apertured spherical cap 10 comprises the anode, the aperture in the cap having a constant section over a distance equal to its diameter. The ratio of the curvatures of anode and photo-cathode should not exceed 1:4. When the electrodes are not truly concentric, the shape of the conductive wall 3 is varied or the distance between the electrodes adjusted to allow reproduction of the same size of surface.

Abstract: 534,602. Rubber articles. INTERNATIONAL LATEX PROCESSES, Ltd. March 28, 1940, No. 5598. Convention date, April 7, 1939. [Class 70] In making articles of, or containing, rubber the former is given a coating of an uncoagulated latex composition of pH value 7.0 or upwards containing a latex coagulant, and a second latex composition coagulable by the coagulant in the first composition is deposited on the coated former. The first coating may be at least partially dried or heated prior to the deposition of the rubber layer from the second composition. Thus, glass formers are dipped into a latex of pH value 8 to 8.1 containing hydrated magnesium acetate, acetic acid, " Aquarex D " and ammonia and when dried into a latex composition containing potassium hydroxide, formaldehyde, potassium oleate, sulphur, zinc oxide, accelerator and antioxidant. Further alternate dips into the two compositions may be made. Zinc acetate, calcium chloride, magnesium sulphate or calcium sulphate may also be used as coagulants. " Aquarex D " may be replaced by other well-known stabilizers.
