Abstract: 933,585. Aircraft controls. ENGLISH ELECTRIC CO. Ltd. Nov. 20, 1959 [Nov, 20, 1958; Jan. 23, 1959; Sept. 17, 1959], Nos. 37450/58, 2648/59 and 31716/59. Class 4. A power-boosted aircraft pitch control system for improving the rate of response in pitch of an aircraft to movement of the pilot's control comprises, in combination with tailplane control means including a pilot's control stick, a tailplane power control jack, and a mechanical linkage connecting the control stick and the jack, an accelerometer positioned in the aircraft to measure acceleration of the aircraft in pitch and to provide an acceleration-responsive electrical signal, electrical transducer means connected to said tailplane control means and operative to provide a signal which is a measure of a physical quantity depending on the control action applied to the pilot's control stick, electrical computer means connected to respond to the acceleration responsive signal and to said signal which is a measure of said physical quantity and operative to produce a boost signal which increases with increase of the signal which is a measure of said physical quantity and decreases with increase of the acceleration-responsive signal, and a connection between said electrical computer means and said power control jack to supply the boost signal to the control jack to supplement the pilot control transmitted along said mechanical control linkage. The pilot's control stick 1 is connected through linkage 2 to the control valve 5 of a jack 3 operating a tailplane 4. The system has an aritificial feel unit, shown diagrammatically at 6, but which may be of the kind disclosed in Specification 727,513, and stick 1 operates the wiper of a potentiometer 7 which supplies a signal #p, i.e. the tailplane angle applied by the stick 1 in the absence of power boost, over line 8 into a function generator 9. A further signal representing g loading derived from an accelerometer 11 and a signal ## representing the first derivative of the pitch angle with respect to time are fed respectively over lines 10 and 19 to generator 9. Height and Mach. number parameters are fed from an aircraft air data system computer 20 through conductors 15 and 16 respectively into another function generator 12 from where signals K 1  and K 2  respectively representing the gain of the power boost system and the value of #/g under steady state conditions are fed through conductors 13 and 14 into the function generator 9. The output signal of generator 9 is K1(#p-K 2 g) + G## and this is fed through conductor 17 into a power control jack actuator 18, the symbol G representing a gain factor. The unit 18 thus feeds an additional boost signal to valve 5 to increase the tailplane incidence by an amount over that demanded by movement of stick 1 to ensure satisfactory pitch handling characteristics of the aircraft. The unit 18 may be switched in or out as desired. Circuitry for generators 9 and 12 is described.

Abstract: 1317736 Magnetic separators VANDERBILT UNIVERSITY 5 Aug 1970 [5 Aug 1969] 37710/70 Heading B2J Particles of different electrical conductivity are separated by moving the particles through successive regions of increasing, substantially constant and decreasing magnetic field strength whereby the velocity, orientation or point of exit from the magnetic field is varied dependent on the electrical conductivity. In the case of variations in velocity and orientation, separation is completed by subsequently applying a separating force or using a mechanical separator. In a first embodiment (Fig. 1) particles 15 are dropped between vertically staggered poles 13, 14 of a permanent or electromagnet 11, 12. Particles will fall unaffected (21) or be deflected (22 and 23) according to their conductivities and densities. In a second embodiment (Fig. 2, not shown) in. which the pole pieces are level, a subsequent separating force is applied by a fluid jet to separate the particles according to their different velocities. In a modification of this embodiment the particles are projected horizontally between vertically aligned poles and the subsequent separating force is provided by gravity. In a further embodiment (Fig. 4) elongated and preferably flat particles are dropped through an unbalanced magnetic field provided by a permanent or electro-magnet with only one pole piece whereby the particles are rotated according to their conductivity and only unaffected (non-conducting) particles will pass through an aperture between deflector plate 88. In modifications, particles may be rolled down an inclined plane through a magnetic field, or may be wound by inclined troughs or endless conveyor belts. Super-conducting electromagnets may be used. The process may be preceded by a conventional magnetic separator.
