Abstract: 1,231,029. Photo-electric displacement measurement. NATIONAL RESEARCH DEVELOPMENT CORP. Dec.8, 1969 [Dec.13, 1968], No.59477/68. Heading G1A. [Also in Division H1] In an apparatus for measuring relative movement between a "scale grating" 3 and an "index grating" 4 in the presence of a collimated beam of light, opaque elements of the latter grating, which elements alternate with transparent elements across the grating, constitute parts of a photo-electric device 4b and are adapted to respond to light incident upon the left-hand surface thereof in the configuration shown, but not to light incident upon the righthand surface. This permits the grating 4 to be used under near-normal incident light conditions in conjunction with a reflective scale grating 3, the light passing first through the index grating 4 from its non-responsive surface, being reflected from the scale grating 3, and finally striking the responsive surface of the index grating 4 and producing a cyclic output from the photo-electric device 4b. The index grating 4 may also be used in conjunction with a transmissive scale grating Fig.3 (not shown). The index grating 4 preferably comprises a glass substrate 4a on which is deposited an array of parallel strips of opaque metal linked at one end by a common transverse strip serving as an output terminal. The active medium of the device comprises an evaporated CdS layer having its upper surface doped with cuprous ions to produce a photovoltaic effect, and covered with an evaporated transparent conductive layer of Au or tin oxide. A photo-resist method is used to shape the CdS and overlying conductive layers into strips overlying the opaque metal strips and interconnected by a common transverse strip serving as a common output terminal at the opposite end to that at which the opaque strips are interconnected. If the photoresist is transparent it may be left on the device, but otherwise it is removed.

Abstract: 1,233,398. Solvent extraction. UNIVERSAL OIL PRODUCTS CO. 11 March, 1969, No. 12624/69. Heading C5E. A process for the solvent extraction of aromatic hydrocarbons from a mixed hydrocarbon feed stock comprises passing said feed stock to an extraction zone, passing a lean solvent composition comprising at least one solvent selected from the sulpholane-type chemicals and the sulpholene-type chemicals to said extraction zone, therein contacting a continuous liquid phase of said feed stock with a dispersed liquid phase of said solvent composition thereby extracting aromatic hydrocarbons from said feed stock into said solvent, withdrawing from said extraction zone a raffinate stream comprising non-aromatic hydrocarbons, and a rich solvent stream containing resulting extracted aromatic hydrocarbons, separating said rich solvent stream to provide a lean solvent recycle stream and an aromatic hydrocarbon product stream, recycling at least a portion of said lean solvent recycle stream to said extraction zone as a portion of said lean solvent stream, and recovering the resulting aromatic hydrocarbon product stream. Solvents mentioned include sulpholane, 2-methyl sulpholane, 2,4-dimethyl sulpholane, 2-sulpholene and 3-sulpholene. The description includes comparative examples in which the solvent forms the continuous phase. The feed stock may be a catalytic reformate.

Abstract: 1,252,587. Aircraft instruments. V. WILCKENS. 4 Nov., 1968, No. 52099/68. Heading B7W. A pictorial situation display system for controlling the attitude and desired path of an aircraft comprises a display screen from which bank angle, pitch angle, lateral and vertical deviation from the desired path are quantitatively estimatable, the pictorial representation of the desired path being a rectangular channel formed by a bottom plane having a centre line, and two vertical side-wall planes are erected on each edge of the bottom plane and each having a longitudinal line in a predetermined relation to the bottom plane, the line formed by the intersection of a conceptual vertical plane through the centre line of the bottom plane and a conceptual plane through the said lines of the side wall planes locating the desired path relative to a pilot's eyes. The planes are formed by dots or lines computed by external sensors on the ground and set up on a cathode ray tube screen in the aeroplane. In landing the channel is seen to bend upwards into the approach sector so that the longitudinal lines on the side-wall planes coincide with a predetermined glide slope. The height of the lines above the runway at touch down being the actual height of the pilot's eyes at touch down. At that moment the perspective angle of the upper edges of the side-wall planes stretches to 180 degrees (see Figs. 2a-2d). In an alternative embodiment the pictorial representation constitutes an aircraft symbol of an imaginary preceding aircraft (see Fig. 8), which symbol is formed of a rudimentary fuselage and wing section and inverted T-shape tailplane section. These sections move relative to each other on the display screen corresponding to the position and attitude of the flying real aircraft in relation to the desired path. At zero deviation the tailplane section fits within the fuselage section with small gaps between its ends and the fuselage, the wings of fuselage section then being horizontal and in line with the cross-piece of the tailplane section. If desired the aircraft symbol and channel symbols may be used in combination. In a landing the displayed symbol represents the real aircraft moving on a conceptual rail-like path which extends to the intersection of the glide slope and runway at which point it becomes horizontal. This point is indicated by the tailplane section dropping relative to the other section. Preferably the ideal flight path is represented on the screen by a reticule. Particularly the desired flight path is represented by a vertical line and the ground at destination by a horizontal line. A plan view of the aircraft symbol may be shown below the horizontal line to indicate lateral and longitudinal displacement from the desired flight path. Equations are given for computing the bank angle for ideal interception. Speed may be indicated by a colour code.

Abstract: 1290997 Flight simulation SINGER CO 19 April 1971 [27 March 1970] 23847/71 Headings B7G and B7W A fixed-based flight simulator includes a system for providing a realistic feel opposing movement of a simulated control member 16, the system comprising motive means 36 driven by a signal commensurate with the difference between electrical signals indicative of the position of the control member and the motive means respectively, the motive means and the control member being connected by a flexible cable 18 having a predetermined amount of slack, thereby allowing differential movement between the means and the member. For example an aileron control wheel 16 drives a rotary potentiometer 22 and a pulley 30 which is connected by a flexible cable 18 to pulley 32, driven by an electric motor 36 along with a potentiometer 40. A summing amplifier 42 receives signals from potentiometers 22 and 40, together with a signal from a tachometer generator 38 representing the speed of the motor 36, a signal from amplifier 44 representing the tendency of the control member to return to centre, and a signal from the flight computer 46 representing the simulated dynamic air pressure. The output from amplifier 42 is fed to a power amplifier along with a dither voltage from oscillator 50, and the output from this drives the motor 36. If the movement of the motor 36 and the wheel 16, and hence of the potentiometers 22 and 40, were identical there would be no difference between the positional signals, but because of the provision of a predetermined amount of slack in the cable 18 initial movement of the wheel 16 causes taking up of the slack before any movement of the pulley 32. Cable tension may be adjustable by means of a turnbuckle 64. Excessive rotation of the pulley 32 due to a malfunction will cause cams (84) and (86), Fig. 4 (not shown), rotatable with the potentiometer 40, to open microswitch (98) to cut off power to the motor.
