Abstract: 431,595. Aeroplane wing spars. DUNCANSON, F., Seaplane Base, Brough, near Hull. April 3, 1934, No. 10019. [Class 4] Sheet metal tubular spars of the kind in which the tube is strengthened at intervals by transverse diaphragms are constructed by first securing to the diaphragms a shell formed of arcuate sheet metal plates and subtending an angle substantially in excess of 180‹ at the centre of the spar section and then uniting to the shell and diaphragms a second shell complementary to the first. In one form, Fig. 1, sections 10, 11 built up from arcuate strips united by riveted butt straps 13 have secured to them corrugated longitudinal stiffeners 30, 31 respectively and bracket members for the attachment of rib booms and struts. Each section is formed with out-turned flanges 20, 21 respectively. Section 11 is then united to diaphragms 12 and the spar completed by riveting upper section 10 to diaphragms 12 and riveting together flanges 20, 21. Corrugated stiffeners 30 on the upper or compression surface of the spar are of greater area than stiffeners 31 on the lower surface ; flanges 20, 21 in the arrangement shown are, therefore, substantially in line with the neutral axis of the spar. The butt straps 13 of one section are staggered with relation to those of the other. The rivets are inserted from the inside near the spar root ; nearer the wing tip, screws threaded into tapped holes in the diaphragms or into nuts previously secured thereto may be used or hollow instead of snap head rivets. At points where additional stiffness is required diaphragms 12 may be of box section or formed from conical pressings 14, 15, Fig. 1, riveted together. Fig. 4 shows a spar comprising segmental Z section diaphragms 22 shaped as shown in Fig. 5 to fit the upper shell of the spar and disposed between each pair of diaphragms 12 throughout the greater part of the spar length. In a modified form the upper shall may be formed to embrace a greater arc than the lower. Specification 326,870<*>, [Class 4], is referred to.

Slide 27 and its sensing cam 28 is coupled by spring 29 to clamping slide 30 and moves, guided by screws 31 to clamp pointer 23 against rail 25. A second, indicator cam 4 on adjuster 2 is coupled through lever 5 and spring loaded rod 6 to indication slide 7 movable against exposure seale 10. Lever 35 is moved to the left to cock the shutter and set the diaphragm and, through its engagement with arm 34, carries slide 27 and clamping slide 30 with it. Pointer 23 is then freed. When ring 48 is set to "Auto", pointer 23 acts as stop for the slide 27 when lever 35 has run down to the right. When the ring is set to " Flash" by selecting a diaphragm value, a cam 47 engages and rotates counter-clockwise the lever 46 to move away from pin 44 on stop 41. When the shutter is then cocked as above, lever 35 engages arm 36 at the end of its travel and releases pawl 37. Stop 41 then swings until pin 44 re-engages lever 46. As the shutter is released lever 35 runs down as before until slide 27 and 30 engage pointer 23 in its position, as clamped by stop 41, corresponding to the chosen diaphragm value. Linear 35 is thus halted and the aperture is set.

Abstract: 1,147,019. Olefin polymerization. SOLVAY & CIE. 5 March, 1968 [20 March, 1967], No. 10658/68. Heading C3P. A process for withdrawing an olefin polymer suspension from a reactor in which the polymerization of olefins is carried out continuously under low pressure in an inert diluent and in the presence of a catalyst, comprises withdrawing a substantial amount of the crude polymer suspension from the polymerization reactor and pouring it into a decanting zone, withdrawing a portion of the polymer enriched broth at least corresponding to the production of the polymer in the reactor and recycling to the polymerization reactor the slightly concentrated polymer containing liquid which is extracted from the decanting zone, through a recycling conduit. At least one of the constituents of the reaction medium is introduced into the slightly concentrated polymer containing liquid which has been extracted from the decanting zone and is being recycled. The constituents preferably added in this way are the monomer, diluent and chain transfer agent, the catalyst being introduced directly into the reactor. The proportions of polymer enriched broth and slightly concentrated polymer containing liquid leaving the decanting zone may be adjusted by means of a regulating valve mounted in the recycling conduit. In the Figure, an apparatus suitable for carrying out the process is shown. Crude polymer suspension is removed from the reactor 1 via the tube 3 and conveyed into the decanter 6. A portion of the concentrated broth discharged from the decanter is conveyed back to the reactor 1 by means of the conduit 7, while the other portion is withdrawn through the valve 9. The slightly concentrated polymer containing suspension is conveyed from the separator to the reactor via the conduit 10 and regulating valve 11. The tube 12 allows the introduction of reaction medium constituents. In an example, a hexane solution of ethylene is polymerized in the presence of a catalyst constituted by the product of the reaction between Mg(OH)Cl and TiCl 4 , the catalyst being activated by triisobutyl aluminium.

IPC: F42B22/08
Filed: 1916-07-28
Abstract: 104,328. Dalen, G. Feb. 24, 1916, [Convention date]. Mines, marine; torpedoes, locomotive.-Relates to hydrostaticallycontrolled devices for regulating the buoyancy of mines and torpedoes, and consists mainly in the use of a hunting switch or like gear which causes the mine to assume a given specific gravity for a given depth of submersion, in order ultimately to come practically to rest at a depth for which the specific gravity of the mine is equal to that of the water. In the form shown in Fig. 1, the diaphragm 8, by means of which the buovancy of a mine 1 is adjusted, is worked through a bell-crank lever 6 by a piston 5 moving in a cylinder 4. A liquid is supplied to the cylinder and allowed to escape therefrom under the control of a valve 11 connected to the hydrostat 2. The liquid is obtained from a tank 10 under a head of compressed air. The seat 14 of the spring 3 of the hydrostat is connected to the piston 4, so that it is displaced simultaneously with the diaphragm 8 to restore the valve to the central position when the buoyancy has been changed to an extent corresponding to a change in the hydrostatic pressure. The slide valve shown may be replaced by a three-way cock. In a modification, the seat of the spring of the hydrostat is fixed, and the hydrostat and the diaphragm 8 are connected to the opposite ends of a lever fulcrumed on the rod of the valve 11. In another modification, the liquid in the tank 10, instead of being forced out by compressed air, is subjected to a piston which is screwed forward by a wound-up spiral spring through the medium of a spur gear. In still another modification, the diaphragm 8 is worked through a screw-and-nut gear and a worm gear by an electric motor controlled by a switch, of which one member is moved by the hydrostat by means of a rack and pinion, and the other member is moved by the diaphragm 8 by means of link-work.
