Abstract: 695,025. Aircraft wings. BLACKBURN & GENERAL AIRCRAFT. Ltd. Aug. 31, 1951. [June 23, 1950] No. 15703/50. Class 4. In an aircraft having wings which may be adjusted to an open or a swept-back position, the main spars 11 of the wings 10 are pivoted on a free hinge 12 and are connected by the links 13 to a fixed pivot 13. Opening and closing of the jack 14, 15 causes the wings to move from a swept-back to a spread position the hinge 12 moving in a fore and aft direction. The wings 10 are kept firm in the plane normal to the dimension in which movement takes place by either having a fixed fuselage member 23 travelling in the slot 22 in the wing, or a member 37 on the wing travelling in a slot 36 in the fuselage. Both the members 23 and 37 are so mounted as to reduce friction while keeping the wing firm. A slight angular displacement of the links 13 may be allowed for by mounting them on a spherical member carried by the pivot 13<SP>1</SP>. In a jet propelled mid-wing aircraft the parts of the wings entering the fuselage may lie between two superposed jet propulsion units.

Abstract: 1473792 Liquid discharge arrangement for centrifuge TITAN SEPARATOR AS 16 April 1975 [22 April 1974] 15735/75 Heading B2P A centrifuge comprises means defining a separating space 7, means (not shown) for introducing a liquid-containing raw material into the space 7, a discharge chamber 19 separate from the space 7, and communicating with it through at least one liquid flow passage 22, 15, 14, 13, 10, 11, a portion of which in the vicinity of the space 7 is formed by the interior of a hollow insert 12 which is mounted in an aperture in an outer wall of the centrifuge and is accessible for replacement from the outside of said wall, and a skimmer disc 20 mounted in the discharge chamber 19 for withdrawing liquid from the chamber. The centrifuge may be of the screw type in which the separating space 7 is defined between the outer drum 1 of the centrifuge and a rotor carrying a solids discharge screw conveyor (not shown). The drum 1 is secured to a flange 2 of a rotary drive shaft 3. An annular disc 9 is secured by means of screws 8 in an annular recess formed in the side face of flange 2 facing the space 7. Pockets 10 are distributed along the circumference of flange 2 and each pocket is in open communication with the space 7 through a gap 11 along the edge of disc 9. Radial holes drilled from the outer periphery of the flange inwards open into the pockets 10. An insert 12 is held in each of three holes by a locking screw 17. Each insert has a blind hole 13 connected by transverse bores 14 with a blind hole 15 in the flange. The discharge chamber 19 is defined between the flange 2 and a drum end cover 18 in which blind holes or recesses 22 connect chamber 19 with the holes 15. The skimmer disc 20 is secured to a bracket 4 and is provided with ducts 21 which communicate with a stationary discharge spout 23. The liquid level 24 in the separating space 7, and hence the radial distance between the surface of the liquid and the outlet (not shown) through which the separated solids are discharged from the space, can be varied by replacing the inserts by other inserts which extend for a shorter or longer distance into the pockets 10. In another embodiment, Fig. 2 (not shown), for separating two liquids and solids an additional set of pockets with respective inserts shorter than the inserts 12 is provided each located between a pair of pockets 10 for the removal of the higher density liquid.

Abstract: 643,222. Mechanical toys. DIE CASTING MACHINE TOOLS, Ltd., and MILLS, A. R. June 18, 1948, No. 16438. [Class 132 (iii)] A toy escape ladder e.g. mounted on a model fire-engine comprises a bottom section 30 pivoted to be raised or lowered at its base and into which an upper section 40 telescopes automatically when the bottom section is lowered. A spring 24 normally causes the ladder to pivot upwards, the upper section thus being extended due to the cable being drawn over the roller 38. To lower and collapse the ladder, cable 65 is wound on winding spindle 60, drawing carrier 50 with figure 45 down and thus causing the upper section 40 to slide down. This in turn causes cable 75 to pass back over roller 38 and to draw the ladder down. The spindle 60 may be locked by moving it laterally so that its turned end is located between two ribs on the vehicle body.
Patent GB-164401-A (GB)
Abstract: 164,401. Fuller, G. C. Dec. 29, 1919. Pocket igniters, frictional.-The body of a pyrophoric gas igniter comprises two hollow sections 2 secured together by tongues 4 and is shaped like a pistol. The U-shaped trigger 14 has a finger-piece 11 extending through a slot in the casing and a rod 13 sliding in end parts 16 on a slightly inclined guide 15 or in pieces formed integral with the casing, the trigger being of metal wire or of sheet-metal of semicircular cross-section. The rod 13 extends through an enlarged hole in a downwardly depending part 24 on a sliding carrier to which a file 26 having teeth on one or both sides is detachably secured by means of a tongue and a screw 27. The pyrophoric material fits in a chamber formed by channels in the two sections 2 at the front of the igniter, and is pressed upwards by means of a spring 33 which is pulled down a slot and pressed into a lateral recess 37 when replacing the pyrophoric material. A spiral spring 38 is inserted on the rod 13 between the rear end part 16 on the guide and the part 24 of the carrier. When the trigger is pulled back against the action of a U-shaped spring 20 within the stock 3, the trigger tilts about the rear end part 16, and a notch in an enlarged part of the rod, by engaging the part 24 of the carrier, moves the carrier backwards until the part 24 engages a cam 39 formed on the underside of the casing. The cam 39 disengages the part 24 from the notch in the rod 13, and the spring 38 forces the carrier forwards, thereby producing sparks.
