Abstract: 570,661. Casting structures in situ. HAWES, A. H. May 24, 1943, Nos. 8195 and 18090. [Class 20 (ii)] Shuttering for casting concrete walls, beams. &c., comprises panels 20, Figs. 1, 2, of wood or metal, having reinforcement, e.g., angle irons 21 on one face, spaced inwardly from the edges, and provided with clamping means whereby the panels may be secured in alignment by. longitudinal angle sections 30. The clamps comprise strips 22 secured to the reinforcement 21 and to the panels and provided with screws 25 for locking the panels to the longitudinals 30, and with a spigot, e.g., a screw 28 at the top of the panel and a socket, e.g., a hole 27 at the bottom of the panel, or vice versa, so that superposed panels may be held in alignment whilst permitting the removal of a lower panel without disturbance of the panel immediately above. The panels are provided with holes 38 for the passage of wires 37 which are gripped by screws 40, Fig. 7, in bars 39, and strained by screw 41 bearing against vertical tubular scaffolding 43. ,Distance pieces 44 between opposite panels maintain the longitudinals 30 in contact with the scaffold tubes, which may be coupled end to end by sleeves 60 and screws 62. The wall is cast course by course by removal of lower panels and the repositioning of these panels at a higher level. Where wires are not required to pass through the wall, they may be secured by screws in lugs on the longitudinals, and strained in similar manner by the thrust of a screw against the scaffolding. Longitudinals 30 which meet, at an angle, e.g., at a corner, interengage by a spigot and socket connection and these longitudinals may be extended so as to be clamped against a scaffold tube 43, Fig. 11, by wires 51 and a thrust screw 41. For casting concrete about an I-girder, Fig. 8, side shutters coupled by wires 37 above and below the girder are employed, these shutters having a base panel clamped thereto by a thrust screw 41 which strains a wire 70 positioned about the girder by pressure against a scaffold tube 43 against which the base panel bears. The claims are limited to the form and positioning of the shuttering and scaffolding, the means for securing the shutters being claimed in Specification 570,678.

Title: Improvements in or relating to means for controlling aircraft, submarines and like totally immersed craft or structures
IPC: B64C13/00
Filed: 1928-03-19
Abstract: 314,105. Thurston, A. P. March 19, 1928. Steering, and balancing.-An aircraft, submarine or other totally immersed craft or structure such as a kite has control surfaces such as the elevator, rudder or wing tip ailerons provided with a small rider plane in front of the leading edge, and means are provided for altering the inclination or position of the rider plane relative to the control surface so as to form a gap of variable inclination towards either side of the control surface. A similar rider plane or a hinged flap is provided behind the trailing edge of the control surface with means for similarly varying its inclination or position. Ths rider plane or flap may be linked to the forward rider plane to assist the positive movement of the, control plane or to effect the movement when a freely pivoted plane is used. Alternatively, the main control plane may be fixed and its aerodynamic effect controlled solely by the rider planes. Fig. 2 shows a crosssection of an elevator 4 pivoted about an axis 5 at each lateral end of a tail plane, the elevator having brackets to which two planes. 7, 8 of symmetrical cross-section are pivoted. Arms 11, 12 on the planes 7, 8 are linked to fixed arms 13 on the tail plane and cables 16, 16<a> connect the arms 12 to a pilot's control. Movement of the cables 16, 16a positively moves the plane 4 and at the same time adjusts the planes 7, 8 as shown. Alternatively the plane 4 with its brackets carrying the planes 7, 8 and the arms 13 may be freely pivoted about the axis 5 so that movement of the cables 16, 16<a> first adjusts the rider planes and the air pressure on the rear plane adjusts the plane 4. In another modification, the plane 4 and arm 13 are moved positively and a lost motion mechanism is provided to actuate the planes, 7, 8 after a predetermined movement of the main control plane. A similar series of planes is de.- scribed as mounted on the upper part of a vertical fin to act as a, rudder and upon transverse axes beyond the wing tips to act as ailerons. The wings may be fitted with alulas as described in Specifications 180,359, 310,988, and 313,419.
