Title: Improvements in or relating to folding wing aircraft
IPC: B64C3/56
Filed: 1943-06-01
Abstract: 574,361. Aircraft wings. FAIREY AVIATION CO., Ltd., CHAPMAN, H. E., and COSTIGAN, F. J. June 1, 1943, No. 8772. [Class 4] A folding aircraft wing in which a part c of the trailing marginal portion of the wing is foldable above or below the forward part prior to the folding of the main wing, has the part c operated by a link k connected to one arm d of a bell-crank lever pivoted about a fore-and-aft axis f on the rear spar of the wing, the other arm e being connected to an operating rod movable transversely of the aircraft. The upper end of the link k is connected by a universal joint to the front of the part c which is shown hinged at its upper edge c<1>. As shown, the operating rod s is connected to an intermediate point r of a floating lever q, one end of which is connected by a link p to the arm e of the bell-crank lever and the other end to a bolt u' for locking the part c in its extended position. The bolt engages holes 12, 13 formed in parts w, x, Fig. 3, on the wing spar and folding part c respectively, and is withdrawn by the rod s prior to the movement of the bell-crank lever. When the part c is folded, a spring-pressed member y closes the gap between the holes 12 and prevents the bolt u from being shot home until the part y has again been displaced by the member x and the holes 12, 13 are in register. Specification 496,003 is referred to.

Title: Process for extinguishing fires by means of precipitates of inorganic substances
IPC: A62D1/00
Filed: 1940-05-17
Abstract: 539,018. Fire-extinguishing. REICH, I. O. May 17, 1940, No. 8852. Convention date, June 7, 1939. [Class 47 (ii)] Fires are extinguished by means of inorganic precipitates which are produced by means of solutions at a point or points beyond the pumps on the way to the burning body. For example, two or more simple or compound solutions are put under pressure and sprinkled from two convergent nozzles, or brought together at one nozzle only. As an example, solution of calcium chloride and sodium carbonate are used to give a precipitate of calcium carbonate.

Abstract: 1386557 Moulding seals TRANSCANADA PIPELINES Ltd 23 Feb 1973 [2 March 1972] 9132/73 Heading B5A [Also in Division F2] A mould (not shown), for making a cupshaped seal 20 for a pipeline pig, is in two parts formed respectively with a part-spherical concave surface and a part-spherical convex surface, which surfaces are arranged adjacent each other but with their axes of symmetry parallel (not co-linear), so that the wall thickness of the seal moulded between the surfaces increases progressively from one edge region 22 of the seal to the diametrically opposed edge region 34. The greatest wall thickness may be twice the least.

Abstract: 887,890. Locking rotary elements by positive detents. SOC. AUXILAIRE D'INDUSTRIE (SADI) S.P.R.L. March 21, 1958 [May 14, 1957], No. 9188/58. Class 80 (4). [Also in Group XXIX] Means for stopping a rotary shaft 1 after a predetermined number of revolutions in either direction for use in the control of valves or gates, comprises a nut 10 which travels, without rotation, axially along a threaded sleeve 6 driven through a planet reduction gear 4 by the shaft 1, until arrested by one or other of two stops 12, 15 according to the direction of rotation, whereupon the nut 10 is turned with the sleeve 6 by a lug 11 or 13 and a peripheral lug 24 or 25 on the nut strikes the tail 21 or 22 of a stop-pawl 19 or 20 pivoting the latter downwards against a return-spring 23 into the path of a projection 27 on the shaft hub 2, thereby stopping the shaft 1 and also actuating a signal through an arm 26. The planet reduction gear comprises a planet 4 carried by the input shaft hub 2, and meshing two ring gears with dissimilar numbers of teeth, one, 5, stationary, the other formed by the threaded sleeve 6. The number of revolutions of the shaft I before being stopped is thus determined by the reduction ratio of the planet gear and the axial travel of the nut 10, which latter can be adjusted by screw-adjustment of one, 15, of the axial stops.

[Class 89 (i)] Screws and nuts are locked by means of a washer-like device fastened to the nut or threaded article with which the screw engages. The fastener comprises a sheet metal section 10 having a base 11 provided with integral thread engaging means 15, 16 so positioned relatively to the threads of the nut that when a screw passes through the nut into engagement with the fastener the thread engaging means forcibly engage the screw being deflected elastically both laterally and axially. The base 11 is initially flat and is formed with turned over ends 12, 13 to engage a threaded abutment 9 on a part to be adjusted. The base 11 cambers slightly on engagement of the parts 15, 16 with the screw thus applying additional spring locking pressure. The screw is retained, in the other part B, against axial movement by a washer 2. The fastener may be applied to a nut by grooving the nut at 32, 33, Fig. 7, to receive the turned over ends of the fastener. Applications to adjustments of carburetters, headlamp reflectors, and the cores of electrical coils are mentioned.

Patent GB-701807-A (GB)
Title: Synthesis of carotenoid polyene compounds having vitamin-a activity
Filed: 1951-04-23
Abstract: Vitamin A-active material is synthesized by condensing b -ionylidene acetaldehyde with an ester of b -methyl glutaconic acid preferably in the presence of a basic condensation catalyst and thereby forming an a , g -dicarboxy condensation product and decarboxylating said a -g dicarboxy condensation product to produce the corresponding a -monocarboxy compound.  The mono-acid may be reduced directly or after esterification by means of L1 AZ H4 to vitamin A alcohol.  The condensation may be effected using an alkali metal as condensation catalyst. Decarboxylation may be effected by heat alone or in the presence of an organic base and metal catalyst, e.g. a tertiary amine and a copper salt.  Saponification of the condensation product may be effected prior to decarboxylation.  Esterification of the vitamin A alcohol may be effected by means of an alkyl halide in the presence of methyl ethyl ketone, an alkali metal halide and an alkali carbonate.  The cis vitamin A product may be converted to trans vitamin A by means of an isomerization catalyst, e.g. iodine. Specifications 633,749, 663,791 and 668,604 are referred to.

[Class 142 (ii)] In a warp let-off device in which a coupling is interposed in the drive of the beam and the tension in the warp is kept uniform by a tensioning device, relative movement between the coupling members 72, 82 is determined by the position of the tensioning device 4 and by a cam 78 or an eccentric rotated by the main drive of the loom. The beam 1 is driven by worm 44 and worm-wheel 45 and bevel gearing 84 from a shaft 15 driven from the main shaft. The coupling 72, 82, which may be a friction coupling, has one member 72 movable by a lever 75 secured by toggle mechanism 73, 74 to a regulating rod 71 secured to the lever 66 carrying the tension beam 4. The toggle mechanism 73, 74 is also controlled by a lever 77 and cam 78 on the shaft 15. In another arrangement, the one coupling member 72 is controlled by the movement of the tension beam 4 and the other is moved by an eccentric upon the shaft 15. In this form, a cam similar to cam 78 is operative to hold the lever 66 and tension beam 4 in a fixed position during the part of the loom cycle in which weft thread is beaten up into the fabric. Alternatively, a hydraulic mechanism may be provided for this purpose.
