Title: Improvements relating to control-systems and control-gear for aircraft power-plant installations
IPC: B64D47/00
Filed: 1947-01-31
Abstract: 625,176. Aircraft engine controls. READ, J. R. Jan. 31, 1947, No. 3095. [Class 4] [Also in Groups XXVI and XXVII] The control gear for a multi-engined power plant in an aircraft comprises a manually - operable main power-lever, and a manu ally-operable throttle or power-lever for each en gine, the latter levers being normally interconnected with the main power-lever so as to move together for simultaneous opening anc closing movements, but also being capable of disengagement from the main lever so as to be movable independently of the latter to a position in the range below the position of the main lever, but not beyond such position. The arrangement shown is intended for the control of a pair of gas turbines 10, 11 driving a contra-rotating propeller 12 through clutches 13, 14, and consists of individual throttle control levers 42, 43 which may be locked to the ends of a pair of arms 47 carried by a master control lever 40. The locking arrangement for each of the throttle levers is such that when one is released the other is locked to the master lever, and abutments 47a on the cross-arms 47 prevent either of the throttle levers from being advanced to a setting beyond that of the other. Each of the three levers is telescopic, the gates being in the form of radial abutments in quadrant plates 41a, The lever 40 may be remotely controlled by the pilot, and the throttle levers 42, 43 may be adjusted by the flight engineer. The method of starting and controlling the gas turbines is as follows: (a) The starting nozzle 23 is ignited by a sparking-plug 24, the fuel valve 27 being operated by a solenoid 26 in parallel with a spark coil 29. (b) Upon moving the levers from the " stop " to " idle " position, the main nozzles 25, which are controlled by a valve 35, are ignited. (c) During movement from " idle " to " start " position, a valve 38 is operated to allow admission of liquid to the clutches 13, 14 in the propeller drive. (d) For normal conditions the levers are adjusted between the " start " and " full throttle " positions, failure of either engine being indicated by illumination of the corresponding signal lamp 62. When reverse-pitch propellers are fitted for braking purposes, the control levers may be advanced beyond the " full throttle " to a " brake " position to operate a valve 70 controlling the blade pitch setting. Specification 612,652 is referred to.

Title: Improvements in or relating to display devices
IPC: G09F23/16
Filed: 1937-02-04
Abstract: 493,278. Changing signs. CHANDLER, W. F., and HILL, H. R. Feb. 4, 1937, No. 3383. [Class 3 (i)] An optical projector 2, 3 for displaying in succession pictures &c. on a film is combined with a clock and has mechanism as shown in Figs. 1 and 3 for advancing the film. The minute-hand spindle 8, driven by the spring 4 of the clock, carries a ratchet wheel 9 with which engages a pawl 30 on a pivoted lever 26 spring-retracted at 29 and having a nose which engages a cam 23 on a shaft 13 driven by a spring 10 or by the spring 4. A second pivoted lever 27 abuts against the lever 26 and is connected thereto by a spring 28. The lever 27 has a hook which takes over a cam 24 also mounted on the shaft 13, but laterally spaced from the cam 23. The shaft 13 is thus permitted by the levers 26 and 27 and the wheel 9 periodically to rotate and to drive through one revolution, by means of equal bevel wheels 16, 17 a spindle 14 carrying an eccentric and sheave 18. The outer end of the sheave is pivoted to a rockable lever 19 supporting a pivoted spring-held hook 20, which in its reciprocation engages the film slots and drags the film 1 step-by-step through the gate. The width of the gate and the throw of the pawl 20 are adjustable to suit different length pictures to be displayed. When the clock is electrically driven, its motor may continuously wind up the spring 10. A cam may be mounted on one of the clock wheels to bring the pawl 20 out of engagement with the film slots for a certain period during each day. In a modified form shown in Fig. 6, five pictures are displayed for one second, followed by one picture displayed for ten seconds. A shaft 33 rotating at constant speed carries a wheel 32 provided with six teeth 34 engaged by a projection 37 on a pivoted lever 35. The rear of the lever 35 engages the step of a cam 39 mounted on a spindle 31 geared to the projector mechanism so that one revolution of the spindle coincides with the passage of a single picture through the gate. A detent 42 engages a stop 41 at the rear of the cam 39. A mercury switch 44 is tilted by a link 43 from the lever 35 to start the motor 45 when the lever 35 is tipped by a tooth 34, but before a revolution of the spindle 31 has been completed the lever 35 falls to engage the step of the cam 39 and stop the motor 45. If one revolution of spindle 31 were to coincide with the passage of more than one picture across the gate, more than one cam 39 would have to be provided.

Title: An apparatus for the winding of roller-driven, cross-wound bobbins
IPC: B65H54/44
Filed: 1964-01-28
Abstract: 1,006,921. Winding yarns. ALGEMENE KUNSTZIJDE UNIE N.V. Jan. 28,1964 [Feb 14, 1963], No. 3651/64. Heading D1J. The invention relates to yarn winding mechanisms in which a package 2, driven by a drum 1, is used to drive a yarn traversing mechanism 15. To reduce the torque that must be transmitted from the drum 1 to the package 2 to drive the traversing mechanism 15, an auxiliary member 21 is provided that supplements the drive to the traversing mechanism 15 via a ribbon or cord like member 13 providing a frictional one way driving effort from the auxiliary member 21. In Fig. 1 the package 2 drives a pulley 9 via a system of belts 6, 8. The pulley 9 and the traversing drum 15, are freely mounted on a spindle 11 but are interconnected by a cord 13 wrapped several times around the spindle 11. An auxiliary variable speed motor 21 drives the spindle 11 in the same direction as the pulley 9 and thus provides a frictional drive that lessens the resistive torque of the package 2 being driven by the drum 1, the speed of the motor 21 varying with the displacement of the bobbin axis as the package grows. In Fig. 3 (not shown) the package 24 drives a shaft 25 on which are freely mounted two belt pulleys 26, 33. A cord 31 is wrapped around a hub of the belt pulley 33, one end of the cord being connected to a clamp 32 on the belt pulley 26 and the other end being connected to a bracket 30 attached to the shaft 25 and extending through a slot in the belt pulley 26. The auxiliary motor 39 drives the belt pulley 33 in the same direction as the package 24, but at a faster speed, and this causes the belt pulley 33 to transmit a frictional drive via the cord 31 to the shaft 25 to reduce the resistance to motion of the package 24.
