Title: Vtol multiple control system
Inventor: GIRLATSCHEK SIEGFRIEND
IPC: G05D1/00

Abstract: 1,074,703. Automatic control of aircraft. VEREINIGTE FLUGTECHNISCHE WERKE G. m.b. H. FRUEHER "WESER" FLUGZEUGBAU/FOCKEWULF/HEINKEL-FLUGZEUGBAU. June 22, 1964 [Feb. 14, 1964], No. 6251/64. Heading G3R. In a stabilizing system for a VTOL aircraft having three identical automatic control chains, if the control signal in one chain diverges beyond a predetermined extent from the signals in the other chains, the faulty chain is switched out together with one of the other chains. In Fig. 6, three signals U1 U2 U3 derived from pick-offs of identical attitude gyros (not shown) are normally applied in parallel to three amplifiers V1 -V3 the normally paralleled outputs of which control electro-hydraulic attitude jet correcting means Q of a VTOL aircraft so as to stabilize its hovering attitude in a reliable manner. Different pairs of signals from U1 U2 U3 are respectively applied to opposed control windings of transductors St1 St3 St5. These transductors are arranged in the input circuits of rectifiers energizing relays A, B, C and when the signals are equal, the impedances of the transductors prevent relay operation. In the event of one signal being different owing to a fault, two of the relays operate appropriate contacts a1-c2 to disconnect the faulty signal and one of the other two to leave only one in control. Operation by momentary disturbances is prevented by delay circuits R, C. Relay operation is achieved by the transductor output overcoming a diode system D3 which together with Zener diode VS also ensures that the relay is held operated thereafter from the D. C. source shown. Under such fault conditions the pilot may change over control to the other good signal by operation of a switch S. Three further transductors St7 St9 St11 compare pairs of outputs from amplifiers V1-V3 and cause relay operation in the event of a fault by operating appropriate contacts a5 -c6 to leave only one output in control in a manner similar to that for controlling the inputs. Further relay contacts a3-b4 operate an alarm or indicator lamp under fault conditions and also prevent operation of all three relays. Modifications are described employing push-pull operation of transductor or transistor-controlled relays.

Filed: 1924-03-13
Abstract: 234,926. Rose, W., and Rose Bros. (Gainsborough), Ltd. March 13, 1924. Packing tea or the like into paper bags or cartons.-Relates to machines, for filling tea and the like into bags or cartons, in which a packet wheel having receptacles for the bags is intermittently rotated to bring the bags to successive positions of rest for filling, folding, &c. According to the invention, a packet wheel is formed with a number of channel-shaped boxes open at the side nearest the periphery of the wheel, and a guard ring partially surrounds the wheel to retain the bags, which after filling or other operations, are ejected through the open sides of the box by a horizontally acting member. The support plates for the bags in each box are adjustably and frictionally held, and adapted to be acted upon by a vibratory device. As shown, the bags are inserted in the machine at position W, Fig. 1, and undergo filling or other operations before arriving at the position X by a series of intermittent anticlockwise rotations. The packet wheel 1, Figs. 1 and 4, carries a number of channel-shaped boxes 2, open at each end and at the side corresponding with the periphery of the wheel. A support plate 22 is arranged in each box on a sliding bar 23, to support the bags, which are inserted at position W, and a roller 28 on a pin 29 engages a concentric and vertically adjustable runway 30, the upper face of which is of inclined or helical shape so that the bag is raised to a predetermined position in the box. The support plate 22 is normally frictionally held in position by a plunger 55 with a pad 56 operating in a boss 54, and urged against the sliding bar 23 by springs 58, 58<a>. In order to remove the frictional pressure of the pad so that vibrating movements may be imparted to the plate 22, a runway 68 acts upon a bell crank lever 64, 65, which is actuated to withdraw the pad. The vibratory movements are imparted by a cam having a wavy contour in a sector 34 which is engaged by the roller 28. The sector 34 is vertically adjustable and may be horizontally reciprocated by means of cams 53, 53a engaging the rollers 48, 48<a> or arms 47, 47<a> connected to the arms 37, 37<a> carrying the sector by a lever 49 and link 44. A guard ring 71 retains the bags laterally in the channels during rotation, and after filling, folding, or other operations have been performed, the bag is ejected at position X. The ejector comprises a member 6 acting through openings 5 in the sides of the boxes and thrusts the packets laterally into a delivery channel 21. According to the Provisional Specification, a rammer may be employed to ensure contact of the roller 28 with the runway 30.

IPC: B23K11/087
Filed: 1954-03-08
Abstract: 781,872. Welding by pressure. TAYLORWINFIELD CORPORATION. March 8, 1954, No. 6634/54. Class 83 (4). In a flash butt-welding machine having fixed and movable platens, each platen being provided with a pair of strip clamping dies, a strip spacing gauge is connected to one platen, the gauge is guided for movement in a vertical plane for positioning between the dies and the gauge has guide bars at its opposite ends for insertion between the platens. Clamping dies 14, 15 are mounted on a fixed platen 11 and dies 17, 18 are mounted on movable platen 12. The dies may be clamped by means described in Specification 766,339. An arm 24 acted on by a fluid-operated actuator 25 is pivoted at 26 to the fixed platen and supports through a pivoted link 23 a carrier 22 for a spacer gauge 19 having several parallel gauging faces thereon. With the platens in the work-loading position the arm 24 is lowered by the actuator 25 and the carrier 22 swings outwardly to position the spacer gauge intermediate the dies and a key 34 engages a slot 33 in the carrier to guide the latter. The tapered guide bars 27 at the ends of the spacer gauge engage guide blocks 28 on the dies and cutter bars 32 on the spacer gauge clean the die faces as the spacer bar is lowered through the dies. The spacer bar is then retracted somewhat into correct spacing position. The strips 20, 21 are moved by rollers 29, 30 towards each other and their ends abut the spacer bar. The dies are then clamped on to the strips in the position shown in Fig. 4. To permit the spacer bar to be withdrawn the platens are slightly separated by a short stroke hydraulic actuator 36, Fig. 6, the piston 35 of which is connected to the platen 12 and the cylinder of which is connected to the pistonrod 38 of the upsetting actuator 39. In the work-loading position the actuators are in the positions shown in Fig. 6. Fluid pressure is applied to the conduit 42 and piston 35 and platen 12 move to the right until piston 35 engages the bottom of the actuator cylinder. The spacer bar is now withdrawn swinging outwardly from the platen 11 and welding of the strips is then effected, the direct contact established between the piston of the upset actuator and the platen 12 allowing large upset pressure to be applied independently of the actuator 36. After welding, fluid is applied to both actuators to cause the piston of the actuator 39 and thus the actuator 36 to move to the right until a nut 40 thereon abuts a stop and to cause piston 35 to move to the left relatively to the actuator 36. The work-loading position of the platens is thus obtained.
