Title: Improvements in high-altitude aircraft
IPC: B64D13/04
Filed: 1940-01-20
Abstract: 538,950. Aircraft cabins. BRISTOL AEROPLANE CO., Ltd., NIXON, F., and MARPLES, E. I. B. Jan. 20, 1940, No. 1258. [Class 4] A pressure cabin having an outlet valve controlled by a pressure-responsive device within the cabin in order to maintain a constant pressure above a pre-determined minimum, has means for maintaining a constant or controlled flow of air from a blower driven from a separate engine, said means acting on the throttle of the engine or the intake of the blower. In one form an outlet valve 13 on the cabin 10 is controlled by a capsule 11 and air is supplied to the cabin by a blower 16 driven by an engine 15 which is supercharged by an additional blower 25 taking air from the cabin. The output conduit 17 of the blower 16 has a restricted passage 18 and the pressure drop across this passage is utilized to control a throttle valve 24 in the engine intake. Alternatively or in addition the input to the blower 16 may be controlled by a valve 29 actuated by a capsule 27 subjected on one side to the pressure in the intake conduit of the blower. In another modification the pressure drop across the passage 18 controls the valve in the intake of the blower 16. In another modification wherein there is a varying consumption of air in the cabin a capsule subjected to the difference of pressure between the cabin and the delivery conduit of the blower actuates a throttle valve in the engine intake which is branched off the blower conduit. In this case a displacement blower may be used, but if a centrifugal blower be used its intake should also be controlled.

IPC: C04B35/16
Filed: 1944-01-24
Abstract: A fused material consisting of, or containing a predominating amount of, non-porous highly refractory magnesium orthosilicate is made by melting preferably in an electric furnace magnesium silicate rock in contact with magnesia under conditions of limited reduction and separating by gravity.  The limited reduction involves 1, using solid carbonaceous reducing substance in an amount not exceeding that required for the reduction of compounds of iron and related metals present and ores of, e.g., vanadium, chromium manganese, nickel-magnesium silicate, nickel oxide or cobalt which may be added to produce a ferro-silicon alloy of low silicon content; 2, replacing part or all of the carbonaceous reducing substance by reducing gas, e.g., carbon monoxide or producer gas, or ferro-chromium to reduce iron, vanadium, nickel cobalt and magnesium from their ores and to add refractory chromium compounds to the refractory.  In any case the bringing of a substantial excess of solid carbonaceous material and magnesium silicate or oxide into contact must be avoided. Specification 482,243 is referred to.ALSO:A fused material consisting of, or containing a predominating amount of, non-porous highly refractory magnesium orthosilicate is made by melting, preferably in an electric furnace, magnesium silicate rock in contact with magnesia under conditions of limited reduction and separating by gravity.

Title: Improvements in or relating to the application of granular material, for example sand, to the surfaces of bricks, building blocks and the like
IPC: B28B11/06
Filed: 1956-01-17
Abstract: 808,288. Coating bricks &c with sand &c. JOHNSON, J. A., and SEDGLEY, F. V. W. Jan 2, 1957 [Jan 17, 1956], No. 1606/56. Class 87(2). Granular material, e.g. sand, is applied from a sand box 17, which is mounted on a frame 10, to the surfaces of bricks, &c., which have been raised into the box through a hole 19 in its base, and, after distribution, is embedded in said surfaces. Two pairs of opposing vertical plates 22, 23 are fixedly mounted on rods 26 in the box and vibrate therewith under the action of motor 18. Each brick passes upwardly on lift plate 31 through the vertical passage, of similar cross section, formed by these plates which have recesses 24 on their internal surfaces communicating through opening 25 with the sand mass in box 17. In operation sand passes through these openings, and after distribution, is embedded in the brick by the beating action of the vibrating plates. Lift plate 31 is raised by the initial clockwise movement of a rocking lever 41 which may be operated by the discharge mechanism, Fig. 8 (not shown) of the brick making press from which bricks are fed to the sanding apparatus. The top of lever 41 is connected by a link having parts 52, 53, the former of which is pivotally connected to a forked arm 47. This arm is coupled by a pivoted link 48 to a clevis 49 fixed beneath the table 31. The clockwise movement of the lever 41 is continued, and link parts 52, 53 are released for guided relative movement by the rotation of a cam 59, Fig. 6, which disengages the projections 58 of the blade springs 57 and the shoulders 56 of member 53 so that lever 41 now moves in contact with a rotatable bar 66 independently of the lift plate which thus returns to its lowered position under gravity. Vertical bars 67 which support bar 66 are thus forced downwards and rock a bell-crank lever 72 which moves a pusher plate 78 inwardly so that sanded bricks are moved onto a conveyer 81. Specification 721,543 is referred to.
