Title: Improvements in or relating to figured ribbed woven fabrics
IPC: D03D23/00
Filed: 1931-02-07
Abstract: 362,238. Figured ribbed woven fabrics. SZILVINYI, (nee GROSS), M. VON, 28, Seilerstõtte, Vienna. Feb. 7, 1931, No. 3975. Convention date, Feb. 8, 1930. [Class 142 (iv).] A reversible fancy ribbed figured fabric is woven with two or more effect warps 1, 2 and thick and thin wefts s, by causing the warps 1 to pass over the thick and under the thin wefts in some parts, as in the stripes a, and in portions of the parts c, d, cl, d<1> and conversely causing the warps 2 to pass over the thick wefts in other parts. In Fig. 2, the black rectangles indicate the raising of warps 1 and the cross hatched rectangles the raising of warps 2, whilst blanks indicate that a weft is raised. Geometric figures are thus produced, the two effect warps being used in equal proportions over the pattern. To cause a change of warp effect as the weaving proceeds, as is necessary in the parts c, d, c<1>, d<1>, the regular succession of picking of first a thick and then a thin weft is interrupted by picking two thick or two thin wefts in succession as shown in Figs. 3 and 4, in the same or different sheds. Four healds S<1> to S<4> threaded as shown may be used. The warps may be of different colours, or of dissimilar material, e.g. thick and thin, shiny and dull. Cotton warps and plant stalk wefts such as flax, hemp, or jute may be used. In a modification hard material warps and wefts of the effect giving materials are used. The fabric may be woven on a dobby or jacquard loom.
Patent GB-490419-A (GB)
Title: Improvements in or relating to aeroplane wing flaps and multiposition actuating mechanism therefor
IPC: H02M7/62
Filed: 1937-02-10
Abstract: 490,419. Fluid-pressure servomotorcontrol systems ; aeroplane flap controls. UNITED AIRCRAFT CORPORATION. Feb. 10, 1937, No. 3989. Convention date, Feb. 15, 1936. [Class 135] [Also in Group XXXIII] Control mechanism for adjusting a movable wing-flap 16 of an aeroplane wing 12 for take-off and landing operations comprises a power piston 46 which is actuated by fluid pressure through a pipe 70 from a high pressure reservoir 66, which is supplied from an electrically actuated pump 56 or a hand pump 162. The piston 46 is connected to the flaps by cables 52 and in its upper position maintains the flap in a normal position indicated at C. The flaps are moved to, and maintained in, positions T or L for increasing the lift of the wing by controlling vents 76 and 78 in the cylinder 40 of the piston 46. For the position T a valve 74 in the line 70 from the high pressure reservoir 66 is opened by actuation of a lever 142 to admit pressure fluid to the piston 46, and a valve 84 controlling the vent 76 to the low pressure or drain tank 92 is also opened by means of another lever 94. The piston 46 thus takes up a position just uncovering the vent 76 which corresponds to position T of the wing-flap 16. To move the flap to the position L the valve 84 is closed thus closing the vent 76 and causing the piston 46 to move farther until the vent 78 is uncovered, which corresponds to the flap position L. To return the flap to its normal position the pressure to the piston 46 is relieved by closing the valve 74 and opening a drain valve 132 to the drain tank 92. This return movement is assisted, and the normal position of the flap maintained without flutter, by power cylinders 112 operatively connected to the flaps and supplied with pressure fluid through a pipe 110 from the pressure tank 66 under control of a valve 106. This valve 106 together with a relief valve 126 is interconnected with the pressure and relief valves 74 and 132 of the power cylinder 40 so that when the power piston 46 is actuated the pressure in cylinders 112 is relieved to allow the movement of the flap and when the pressure in the power cylinder 40 is relieved, fluid pressure is supplied to cylinders 112 to restore the flaps to their normal position. This interconnection is shown as a shaft 134 with a lever 136 coupled to the actuating cable 144 from the lever 142, and cable connections 138, 140. This control arrangement with the vents 76 and 78 in the cylinder 40 permits of only the three positions of the flap being obtained but in a modification, a plunger valve controlling a number of vent ports along the side of the cylinder 40 is provided so that a corresponding number of flap positions are obtainable.

Title: Method of making a cellular rubber article and product thereof
Filed: 1950-02-20
Abstract: 668,948. Moulding cellular rubber. TALALAY, J. A. Feb. 20, 1950 [Jan. 6, 1950], No. 4274/50. Classes 70 and 87(ii) Sponge rubber articles containing a cavity are obtained by subjecting a mass of a foamed dispersion of rubber to refrigeration of such degree and duration that it freezes part, but not all of the foam, irreversibly coagulating the frozen portion and providing a cavity in the mass by effecting collapse of the foam of the unfrozen part of the foam. A closed cell foam may be enclosed in a spherical mould, Fig. 1 (not shown), and the filled mould subjected to a quick, extreme, and briefly maintained reduction of temperature so that the outer layer shell freezes and after a time the non-frozen foam in the centre collapses and leaves a cavity. The outer layer of foam is then irreversibly 'coagulated, either by freezing alone or else by means of a suitable coagulant such as carbon dioxide which is passed through the interior of the mould by inlet and outlet pipes. In a modified mould, Fig. 2, each section is provided with a metal grid 16 in its moulding face, each grid extending so as nearly to touch each other when the mould is closed. These grids enable quick refrigeration to be effected thus forming spaced cavities 18. In Fig. 4, cores 19 produce a permanent cellular wall at 20, and Fig. 6 shows a mould which may be made from a length of cylindrical metal tubing. In this case the interior of the mould may be given a slight taper in order to permit removal of the finished product. Specifications 455,138, 553,513 and 619,619 are referred to.
