IPC: B64C1/00
Filed: 1923-11-19
Abstract: 229,379. Armstrong Siddeley Motors, Ltd., and Lloyd, J. Nov. 19,1923. Strut and tie-rod connections.-Sleeve-like clips encircling a tubular member for the attachment thereto of ties and struts in aircraft and other structures are secured in position by fasteners, adapted to flex under load, passing right through the joint, one or both ends of each fastener having a screwed nipple with a head bearing on the outside of the joint and a cylindrical body extending into the interior of the tubular member. The heads and nipples tilt and exert a pinching action upon the joint as the fasteners flex under load. Figs. 1 and 3 show a portion of a tubular member A to which are secured various struts F, J, K, L and' ties. The tube A is surrounded by a split sleeve B which is encircled by a two-part clip C, C<2> having lugs C<3>, C<4> provided with holes for the attachment of ties and of the struts J, K. Further strengthening pieces H<5>, H<6> are riveted through the lugs C<3>, C<4> where the struts are attached. The sleeve B and clip C, C<2> are secured to the tube A by members D having screwed ends which are engaged by nipples E having cylindrical portions E<2> engaging corresponding holes. The heads of the nipples are non-circular and look nuts or other locking means are provided. Any bending of the members D results in the nipple heads exerting a pinching action on the joint. The strut F is secured to an evebolt H and the strut L has a shank L<2>, both the eyebolt and shank passing right through the joint, the shank L<2> clamping a wiring lug M against a boss on the member H<5>. The strut F has a liner F<2> and socket G secured by members similar to the members D, the liner being omitted from the other struts. Fig. 6 shows a simpler joint in which a flanged clip N surrounds a sleeve B, strengthening- plates 0 being riveted thereto to reinforce the strut connection. Fig. 8 shows a tube end having a sleeve B, hollow plug Q, and clip U secured by members D, a strut T and a wiring lug S being secured to the plug Q by an eye bolt R. A screwed stem W may secure another strut in position. The members D may each have a permanently fixed head at one end.

The shaft 21 rotates in a bush 20 and contains within its interior a spring biased push rod 24 connected at one end to the inductor holder 17 and at the other end to an actuator cylinder 26. When it is desired to change one inductor 18 for another, the actuator cylinder 26 shifts the holder 17 so that the coolant and electrical connections 28 of the inductor are disengaged from the coolant and electrical connections 27 of the transformer secondary. The holder 17 is then indexed to the required angular position, whereupon the actuator cylinder 26 is exhausted to enable the connections 28 of the fresh inductor to automatically engage connections 27 of the transformer secondary. The traverse of carriage 12 is controlled by limit switches adjustably positioned along rails 9 and the heating and cooling sequences by timers. As shown, a rotary shaft 4 carries four rotary crank-shafts 7 and indexes them successively into the heating position and quenching position. Instead of the quench tank 2 shown, the inductors 18 may have spray quenches. Once programmed, the apparatus automatically performs all the hardening operations on all the bearing surfaces, including the exchange of inductors. If used with an automatic feeding loading and unloading apparatus, continuous automatic operation is possible.

Abstract: 335,068. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. W., and Kell, R. D.). Oct. 17, 1928, [Convention date]. Thermionic amplifiers and relays.-In a multivalve amplifier in which the coupling-elements are constituted solely by resistances so that the amplifier responds equally to alternating or direct current impulses, instability due to temperature changes in the coupling-resistances is prevented by causing fluctuations in the output circuit of the valve 5 to control the intensity of an auxiliary source of light 25 directed on photo-sensitive cell 8 receiving the main light-and-shade effects to be transmitted. Any excessive current swings a square piece of paper 31, Fig. 2, mounted on the indicator 32 of a galvanometer in front of an aperture in a screen 30, so as to diminish the amount of light from a lamp 29 tailing on the input cell 8; whilst any diminution in output the paper 31 so as to increase the action of the lamp 31. The valve 3 is coupled to the valve 4 through an anode resistance 14 and a resistance 17 directly connected to the grid, without the interposition of a. coupling-condenser.
