Patent GB-1111322-A (GB)
Title: Elevator control system
IPC: B66B1/16
Filed: 1965-07-06
Abstract: 1,111,322. Lift control systems. TOLEDO SCALE CORPORATION. 6 July, 1965 [6 July, 1964], No. 28651/65. Heading B8L. [Also in Division G3] A lift motor 31 is supplied from Ward-Leonard generator 34, the field winding of which is energized through silicon-controlled rectifiers having phase control firing circuits 35. A signal representing the position of the car is derived from potentiometer 36 and is compared in summer 38 with a reference signal from generator 39 which commands the car-position as a function of time. The error signal is applied to the control circuits 35. A call request is applied to generator 39 from call selector 44 associated with potentiometer 45 having tappings corresponding to landing-positions. When a new floor-signal is applied to generator 39, it affords a positiontime control signal which is regulated so that the first, second, and third time-derivatives of displacement are limited and subject to adjustment. The generator 39 comprises an acceleration generator which is subject to limiting values of rate of change of acceleration, acceleration, and velocity, and whose output is integrated to produce a velocity signal. This signal is further integrated to afford the reference signal applied to summer 38. The reference signal results in an initial period of constant rate of change of acceleration to a maximum acceleration which continues for a second period until the predetermined maximum velocity is approached, a third period of transition from maximum acceleration to maximum velocity, a period of constant velocity, a fifth period of constant rate of change of acceleration to a maximum negative acceleration, and a period of maximum negative acceleration. The pattern signal is changed, as a stopping-position is approached, to one based on the distance from the destination, and is allowed to decrease exponentially. When the reference signal is less than that required to achieve maximum velocity, and slowdown is initiated during the acceleration period, the rate of change of acceleration continues smoothly through zero to a negative value. A stop from maximum velocity is computed by storing the displacement signal generated in achieving maximum velocity and comparing that signal with one representing the distance remaining to be traversed. This distance is ascertained by subtracting from the destination signal the pattern position signal. When the monitored difference equals the stored signal, the transition to deceleration is initiated. A stop from acceleration is computed by continuously generating the instantaneous stopping position signal during acceleration and comparing it with the destination signal. If a call for stoppage is imposed after the lift could be stopped within its acceleration, and rate of acceleration limits, the call is rejected.

Title: Improvements in or relating to spray coating systems
IPC: B05B5/08
Filed: 1954-10-08
Abstract: A method of spray coating articles whose vertical dimensions are greater than the maximum vertical dimension of an expanding spray of finely divided particles of liquid coating material projected outwardly from a central vertical axis in a generally horizontal direction is characterized in moving the articles through the expanding spray along a helical path the axis of the helical path being generally coincident with the axis of the expanding spray.  As shown in Fig. 5, the articles are suspended from an endless conveyer travelling on a helical track 56b so that <PICT:0772141/III/1> at the highest point the bottoms of the articles are level with an electrostatic spraying disc 51 and at the lowest point the tops are level therewith.  The articles are rotated as they travel through the spray.  The disc is rotated and maintained at a high potential, the articles are grounded.  To coat articles of various lengths the height of the disc may be varied or a pivoting disc may be used or suspensions of different lengths.  The articles are led to the helical track by a track 56a and and led from it by a track 56c, the tracks being suspended from supports 59.  The pitch of the helical track may be varied by securing the ends to supports 60, 61, pivoted to a centrally pivoted lever which is suspended by a cable operated by a drum and crank 65 to alter the inclination of the lever.

Patent GB-818380-A (GB)
Title: The recovery of manganese by electrolysis
IPC: C25C1/10
Filed: 1955-10-12
Abstract: <PICT:0818380/III/1> In the electrolytic recovery of manganese, the anolyte is contacted with a manganese hydroxide concentrate containing iron and either or both of nickel and cobalt, the pH of the solution is brought to 4 to 6 to precipitate iron which is separated, the pH is then adjusted to 4 to 6.5 and a soluble sulphide added to precipitate nickel and/or cobalt, to form a catholyte which is passed to electrolytic cells to recover manganese values as metal or oxide; the anolyte is thereafter recirculated for contact with further manganese hydroxide concentrate.  The concentrate may contain manganic hydroxide in which case the contact with the anolyte is effected in the presence of a reducing agent such as ferrous sulphate.  As shown in the flow sheet, the manganese hydroxide is digested in the anolyte in step 1 preferably in the presence of a reducing agent such as ferrous sulphate or metallic iron.  The manganese hydroxide may be derived from the waste effluent from uranium recovery processes which effluent is first treated for the precipitation of the bulk of the iron so that the manganese hydroxide employed includes calcium sulphate and iron, cobalt and nickel impurities.  The acidic treatment in step 1 precipitates calcium sulphate which is removed and the solution is passed to step 2 where it is treated with manganese dioxide to oxidize the iron to the ferric state.  The solution is next passed to step 3 where lime is added to adjust the pH to 5.5 to precipitate ferric hydrate and any cadmium or arsenic.  The liquid is then passed to step 4, and treated with a soluble sulphide at a pH over 4 and preferably 6.5 to selectively precipitate cobalt and nickel.  Ammonium sulphide is preferably employed.  The cobalt and nickel precipitate is separated from step 4 and the solution passed to step 5 to form the catholyte for the electrolysis step 6.  The solution may be adjusted to contain the right amount of ammonium sulphate and to bring it to the correct pH in known manner.  The manganese is preferably recovered as metallic manganese from the electrolysis step and the ammonia generated is used for making up the catholyte in step 5.  The anolyte is recirculated to step 1 after chilling to crystallize complex sulphates of magnesium, manganese and ammonium which tend to build up in the system.  Specification 818,379 is referred to.

Title: Device for training pilots and observers in handling aeroplanes
IPC: G09B9/12
Filed: 1921-11-03
Abstract: 192,754. Horn, G. Nov. 3, 1921. Teaching and training, apparatus for.- For training pilots and observers, an aeroplane, fitted with a motor and propeller and mounted in gimbal rings, has adjustable surfaces for counteracting t h e motor torque in addition to other means for controlling the lateral attitude of the machine. Movable targets are provided, or a map may be wound upon rollers beneath the machine and provision made for lateral movement of the machine or map. Fig. 2 shows one form of the apparatus in which an aeroplane body 1 is connected by stays 2 to a ring 3, which can turn freely within a ring 4. The ,ring 4 is pivoted at 5 within a ring 6, which can turn about horizontal trunnions 7 within a frame 16 capable of being traversed along a girder 13 by a screw 17. Planes 8 are adjusted to counteract the torque of the motor, and the lateral balance is controlled by enlarged planes 9 or by connections to the ring 4. The usual rear steering-surfaces are fitted. A map 14 is moved by gearing 15 at a speed known to the instructor, and the pupil, after estimating the speed, sets the sights of a telescope and drops a shot from a gun on to a selected target. A pendulum may carry a disc of paper which is pierced when the shot is released so as to indicate to the instructor whether the telescope has been correctly sighted. Alternatively, the gun may be fixed to the pendulum, the correctness of the sighting being determined by observing if the shot hits the target. To reach a laterally placed target, the aeroplane is turned and the blast from the propeller turns one or other of two fans 21 adapted to drive the screw 17 to traverse the aeroplane in the appropriate direction. A vane 22 is simultaneously thrown over to throw in either of two clutches 23. Where there is sufficient room, the aeroplane may be turned right round, mechanism being provided for slowing down and reversing the motion of the map as the aeroplane is turned. Instead of traversing the aeroplane, the map may be laterally moved as the aeroplane is turned. A modification is described in which the gimbal rings are mounted beneath a fixed framework and movable targets are carried on wires stretched between posts.
