Title: Roller conveyor
IPC: F16D11/04
Filed: 1971-06-14
Abstract: 1293720 Roller conveyers HANS VOM STEIN OHG 14 June 1971 [16 June 1970 20 April 1971] 27738/71 Heading B8A In Fig. 3, conveyer rollers 21, 21a on rotatable shafts are driven by a shaft 27 through worm gearing 26a, 25 but, under the control of an article sensor 43, the drive is disengaged by movement of the worm 26a along the shaft 27 away from a pinion 30 rotatable on the shaft 27. The worm 26a is axially movable but non-rotatable on the shaft 27. Axial movement of the worm 26a to the left in the figure causes coupling projections 33, 34 of the worm and pinion 26a, 30 to be disengaged although the pinion 30 is continuously driven by a pinion 29 secured on a main drive shaft 28. The worm 26a is normally urged to the right by a spring 32 but when a shaft 40 is rotated by depression of the sensor 43, a comb 38 engages the worm 26a which moves to the left until the coupling 33, 34 is disengaged. Worms 26 are secured to the shaft 27 so that rollers 21 are driven/undriven with roller 21a. Other groups of rollers 21b, 21c are controlled in a similar manner. In a modification, Fig. 7, each roller 51, 51a has a worm 56 which is axially movable for coupling/uncoupling with a double bevel wheel 55 driven by a chain 67 via chain wheels 65 and bevel wheels 66. A comb 73 for each worm 56 is controlled by an article sensing arm 71, the arm to the left of the figure controlling the three rollers 51 by a wire 75 connected to combs 73 of these rollers. In Fig. 10 (not shown) a belt (85) drives pulleys (80, 83) of which pulley (80) has teeth (61) for releasably coupling with teeth on the worm (56). The worm gear prevents over-running of the rollers and thus provides braking for the articles

Title: Improvements in or relating to safety devices for aircraft
IPC: B64C13/42
Filed: 1947-10-17
Abstract: 635,742. Fluid-pressure servomotor-control systems. FAIREY, Sir C. R. Oct. 17, 1947, No. 27877. [Class 135] [Also in Group XXXIII] In a multi-engined aircraft, each engine has a sensitive device associated with it and operable when the engine thrust or torque falls below a predetermined value, to actuate a servotab to cause a control surface, such as a rudder or aileron, to be moved to counteract the out - of - balance forces arising from failure of the engine. In the arrangement shown in Figs. 2, 3 and 6, for a twinengined aircraft, each engine mounting includes two spring boxes 16, one of which is connected to a link 24, movement of which occurs when the engine thrust falls below the predetermined value. Each link 24 is connected by a bell-crank 25 and links 26, 26a to the control valve 27 of a hydraulic jack 28, the piston-rods 29, 30 of which carry pulleys 32 over which pass cables 33, 34 connected to a chain 39 engaging a sprocket 40 which operates the tab 36 through a screw-jack 41. Upon failure of one of the engines the associated linkage actuates the hydraulic jack 28 to move the servo-tab 36 and main control surface in the appropriate direction to counteract the unbalanced force set up. An over-riding pilot's control 37 for the tab is provided. together with micro-switches 55 by which the blades of the propeller of the defective engine may be feathered. Fig. 17 shows an arrangement for a four-engined aircraft, the spring boxes of the port and starboard pairs of engines being connected by differential linkages 81, 82, 83 and 85, 86, 87 connected to links 84, 88 operating the follow-up levers 89, 91 of the valve 27 controlling the jack 28. The points of connection of the links 84, 88 with the levers 83, 87 are so arranged that the response of the jack varies according to whether an outboard or inboard engine fails. Fig. 22 shows a further arrangement in which the spring boxes each operate a micro-switch controlling a solenoid 94, the solenoids of the respective pairs of inboard and outboard engines being in opposition and connected to a link 95 corresponding to the link 83 of the previous construction. The ends of the link 95 carry pins 96 which may be engaged by forks 97 to lock the mechanism. If the aircraft is fitted with turbine engines, each engine may be pivoted on an axis passing through its centre of gravity, and provided with a thrust arm pivoting at one end about that axis and connected at its other end to a linkage operating the jack control valve. In the case of a radial engine the ring mounting may include spring boxes which come into operation when the engine torque falls below a selected value, Figs. 14-16 (not shown).
