Abstract: IMPROVEMENT IN HANDLE OPERATED INCLINER CHAIR               ABSTRACT    An incliner chair has a combined seat and backrest member moveable from a normal occupant sitting position to an occupant inclining position by means of a mechanism attached to a stationary chair frame, by an occupant-operable handle. The handle causes a rotary element connecting identical mechanisms on either side of the chair to actuate linkages that simultaneously thrust out a footrest member and pull down and forward the rear of the seat part with its attached back while thrusting up and forward the front of the seat. A two link control assembly is provided to control and guide the back from moving backward from its normal position to the inclined position and comprise a control link attached intermediate its length to a toggle plate which is itself pivotably connected to the chair frame upwardly and rearwardly of the axis of the rotary element. The toggle plate is pivotably attached to a primary thrust lever at a point allowing the back control lever to be pivoted intermediate it and the toggle frame pivot point. One end of the back control link is attached to the rear of the seat bottom and the other end is attached to a guide link which is in turn attached to the chair frame, and is the second link in the control assembly.

Abstract: ABSTRACT OF THE DISCLOSURE     IMPROVEMENTS IN OR RELATING TO LINEAR MOTORS AND CONTROL          CIRCUITRY THEREFOR     The relative position of the armature and stator of a linear motor is controlled using the outputs of two optical transducers 14 and 15 in phase quadrature from an optical graticule disposed along the length of the stator.  An analogue, velocity-indicating signal is derived from the output of the photoelectric devices 14 and 15 which are also digitised and used to cycle an up/down counter 317 which produces as an output a ten-bit digital word representing the armature position.  The outputs of this counter 317 are used as the ten higher order bits of the twelve-bit digital word representing the armature position which is compared by means of a comparator 316 with a demanded armature position.  The two lower order bits of the actual-position word are derived directly from the digitised outputs of the devices 14 and 15 so as to eliminate the effect of variation in the exact position at which the counter 317 is reset to zero by a position-detecting switch 340.  While the positional error is large, the motor is servoed in accordance with a predetermined velocity profile and, when the higher order bits of the position error word are zero, the circuitry switches over to a position-servo mode using as the actual position signal, the analogue output of one of the two photoelectric devices 14 and 15.  The commutation of the motor coils 415 and 416 is controlled in accordance with the seventh and eighth bits of the output of counter 317, the graticule spacing being chosen so that it equals the commutation spacing divided by 2 raised to an integral power.          The polarities of the drive signals to the motor coils 415 and 416 is additionally controlled in the position servo-mode in accordance with the slope of the analogue output of the selected photoelectric device 14, 15 so as to achieve the correct, negative feedback action.

Abstract: ABSTRACT OF THE DISCLOSURE        A control system for controlling a multilayer headbox for a paper machine.  There are three channels converging in the direction of flow and through which stock is conducted from separate inlets to discharge slots at the slice opening for discharge of layer-forming stock jets.  Each channel is connected by a feed pipeline for stock supply by means of a motor-driven pump, the speeds of which are controlled by individual speed regula-tor units.  The control system includes a first controller, which emits an output signal as a function of a possible deviation of an actual value of the pressure of the stocks inside the headbox from a set point for the pressure. The signal is transmitted to all speed regulator units in order to control the speed  of the respective motors, pump driving to alter synchronously the stock supply to the channels.  The control system additionally comprises ultrasonic transducer means arranged in proximity to the slice opening in order to obtain information about the distance between two channel-forming surfaces in respective channels, which distance information is transmitted to an electronic measuring unit connected to the transducer means and also two controllers, which each receive a measurement signal from the electronic measuring unit representing an actual distance value obtained and which compare this actual distance value with a setpoint and, in response to a possible deviation, emit an output signal to the speed regulator unit for the motor which regulates the stock supply to the channel in question.

Abstract: ANIONIC AND CATIONIC REMOVAL OF COPPER FROM CYANIDE-CONTAINING REMOVAL OF                     ABSTRACT OF THE DISCLOSURE A method for removing low concentrations of solu-ble copper in the form of cupric cation and cuprocyanide and cupricyanide anions comprises first adding ferric cation, or ferrous cation and a soluble oxidizing agent, in an amount in excess of the stoichiometric amount required to form the ferric salts of the cuprocyanide and cupricyanide anions, and after a predetermined time adding an environmentally acceptable soluble precipitant to precipitate substantially all of the remaining excess ferric cation. By this pro-cedure, very small concentrations of soluble cupric cation and the ferric salts of the cuprocyanide and cupricyanide anions, which are typically present in such low concentra-tions that they remain essentially permanently suspended in colloidal solution, are removed by the insoluble ferric compound which is present in much higher concentrations.

Abstract: ABSTRACT:                In a rotary fan beam computed tomography appar-atus using recurrent relative displacement between the source and detectors (e.g. a deflected spot X-ray tube) for the recalibration of detectors in chain-like sequences across the detector array by successive pair-wise common-path sensitivity comparisons starting from a terminal detector, each sequence normally involves 30 or more suc-cessive comparisons, and consistent but unpredictable errors are found to occur,  leading to incorrect Hounds-field values in the computed image matrix. The improve-ment comprises locating at least one radiation trans-parent detector of high stability in front of the array at an intermediate point and using the output to further correct the chain-corrected detector sensitivity  values. One detector comprising a plastics scintillator optically coupled to a photomultiplier is described, whose output pulses are counter during a rotational scan and compared with the mean corresponding measurement from other detec-tors lying behind the one detector, to form a  sensitivity ratio. From a corresponding ratio and data derived during calibration, a measured sensitivity value for the other detectors, is  determined for each scan and is compared with the corresponding chain-corrected sensitivity value to generate a further sensitivity correction value which is then distributed among the detectors of the comparison sequence.
