Title: Improvements in and relating to aircraft controls
IPC: B64C13/24
Filed: 1944-07-06
Abstract: 587,682. Controlling aircraft. GENERAL AIRCRAFT, Ltd., and WELS, O. July 6, 1944, No. 12955. [Class 4] In an aircraft having port and starboard control surfaces arranged for alternative deflection in the same direction and in opposite directions, e.g. elevons, and provided with tabs which assist their operation in the sense necessitating the greater effort but have no effect, or a reduced effect, in the other sense, the tab on the port control surface is connected to and operated by the starboard control surface or its associated control mechanism, and vice versa. In one form, Fig. 1, the wing 1 carries port and starboard elevons 2, 2a operated through linkages 6, 7 and 6a, 7a by a control column 4 and wheel 5, fore and aft movement of the column producing movement in the same direction as elevators and rotation of the wheel producing differential movement as ailerons. Port and starboard tabs 3, 3a are connected by rods 9, 9a (see Fig. 2 (not shown)) to the hinges 8a, 8 on which the elevons are mounted. When the elevons are operated as elevators, no relative deflection of the tabs occurs, but, when the elevons are operated differentially, the tabs are deflected,and assist operation. In another form, Fig. 3, the port and starboard tabs 3, 3a are connected through linkages 9, 9a to levers 10a, 10 forming part of the control mechanisms 6a, 7a and 6, 7 of the starboard and port elevons respectively. The operation is similar to the construction of Fig. 1. In a further form, Fig. 4, applicable to the case in which a greater effort is required to move the elevons in the same direction than is required to move them differentially, bellcrank levers in the linkages 6, 7 and 6a, 7a are connected by links 15 and 15a to the upper and lower arms of a lever 13 pivoted at 14 to another lever 11 pivoted to the aircraft at 12, the linkages 9, 9a of the tabs 3, 3a being connected to the lever 11. When the elevons are operated as elevators, the lever 11 is not moved and consequentially the tabs 'will be deflected relative to the elevons. When the elevons are operated differentially, the lever 11 swings to left or right and operates the'tabs differentially in the same sense so that no deflection occurs. A practical form of the construction of Fig. 3 is illustrated in Fig. 5 (not shown). The tabs are adjustable by the pilot for trimming purposes, see Fig. 6 (not shown).

Abstract: 1,101,075. Hydrostatic gear control. JOSEPH LUCAS (INDUSTRIES) Ltd. 8 April, 1965 [31 March, 1964], No. 13272/64. Heading F2D. [Also in Divisions E1 and G3] In a machine such as a coal-cutter having two pump-motor drive-transmission systems comprising a first pump 14 feeding a first motor 10 driving a coal cutter 12, and a second pump 18 feeding a second motor 17 driving a trolley 11 which traverses the cutter 12 across a coal face 13, the capacity of the second pump 18 only is varied by a swash-plate 26 controlled by a stepped servo piston 24 controlled by an internal spool valve 29 which responds to the working pressure 15 between the first pump 14 and motor 10 to increase the capacity of the second pump 18 when said pressure increases. Thus, when the cutter 12 reaches a pre-cut recess 22 at the end of the coal-face, pressure 15 vanishes, permitting a spring 35 to move the spool-valve 29 to the right to set the delivery of the traverse pump 18 to a minimum determined by an adjustable stop 47. When, after actuating a traverse-reversing valve 19, the cutter 12 again contacts the coal face, pressureincrease in the line 15 acts on the face 46 of a rod 34 to move the spool valve 29 to the left, with consequent follow-up of the servo piston 24 to increase delivery of the traverse pump towards its maximum. Overload protection is provided by a further valve 43 also subjected to pressure 15 of the cutter pump to limit the maximum setting of the traverse pump 18. Servo pressure for controlling the swash-plate 26 of the traverse pump 18 is provided by delivery pressure 20 of that pump acting constantly on the small left end of the servo-piston 24 and fed to its larger right end, when required, through a passage 27, restrictor 28 and inlet port 31, normally covered by the spool valve 29, which latter similarly covers an exhaust port 32, exhausting the right face of the piston 24 on appropriate movement of the valve. The overload valve 43 independently exhausts the right face of the piston 24 when cutterpump pressure 15 is sufficient to rock a lever 38 against an adjustably-loaded spring 39 by acting on a piston 42. The restrictor 28 prevents simultaneous exhaust of the left face of the piston 24 so that the latter is moved right to reduce capacity.

Patent GB-138544-A (GB)
Abstract: 138,544. Siemens Bros. & Co. and Pettigrew, T. July 2, 1919. Automatic and semiautomatic exchange systems.-In a system in which a selector G is accessible both from an ordinary subscriber S and from an operator's switchboard O, the operator's junction J has access to it over one or more contacts, individual to the junction, of a relay Y energized when the called subscriber replies. In this way, the supervisory signal SL at the operator's position is controlled by changes in the junction circuit, unnecessary changes in the circuit of a calling subscriber being thus avoided. The automatic subscriber S sets up a call in the usual manner, the impulse relay A being operated over its windings 2, 3. When an operator inserts a plug in the jack of a junction J, the relay L, energized over the coil RC, operates the preliminary selector VW<1> in the usual way. When an idle selector G is found, the impulse relay A is energized over its winding 3 and coil RC. The operator connects up her impulse-sender I by depressing key K, and operates the impulse relay A over its winding 3. When the called subscriber answers, relay Y connects winding 2 of relay A to the tip side of the junction, thus energizing relay SR, which open-circuits the supervisory lamp SL. When the called subscriber hangs up, relay SR de-energizes and the lamp SL again glows.
