Title: Improvements in and relating to colour photography
Inventor: NORDMAN CHARLES
IPC: G03C7/14
Filed: 1930-09-17
Abstract: 363,387. Colour photography. NORDMANN, C., Observatoire de Paris, Avenue de l'Observatoire. Paris. Sept. 17, 1930, No. 27696. Convention date, Sept. 17, 1929. Drawings to Specification. [Classes 97 (i) and 98 (ii).] Colour-record images on lenticular films, which may be projected without dominant hues in ordinary projection apparatus, are produced by employing in front of and close to the lenticular film in the taking camera a convergent lens which causes the axes of the beams of light which reach each lenticular element from the centre of the colour-selecting filter to converge to a point at a finite distance behind the lenticular surface ; and printing upon a sensitive lenticular film from the original so produced a contact copy in which, therefore, the axes of the beams of light from the centre of the image of the colour-selecting filter in each lenticular element, when the copy is illuminated from behind, will converge to a point at a finite distance in front of the lenticular surface. On projecting the copy, the colour-selecting filter is placed in front of the copy at this point, unless the point falls within the projecting objective, when the appropriate conjugate point must be chosen. The convergent lens may be combined with or separate from the camera objective. If the original film itself is to be projected, a convergent lens similar to that used in the taking camera must be placed in front of and close to the original film in the projector. Specifications 360,524 and 362,490 are referred to.

Title: Improvements in aircraft wings
Inventor: LOBELLE MARCEL JULES ODILON
IPC: B64C3/56
Filed: 1955-09-29
Abstract: 797,376. Aircraft wings. M. L. AVIATION CO., Ltd. Sept. 18, 1956 [Sept. 29, 1955], No. 27759/55. Class 4. An inflatable aircraft wing is fitted with an internal bracing structure capable of being collapsed to allow the wing to be collapsed, and of sufficient rigidity when locked in the operative position to maintain the general form of the wing sufficiently to keep the aircraft airborne in the event of loss of air from the wing whereby the wing can function with its interior either at atmospheric or at super-atmospheric pressure. In Figs. 1 and 2, the framework comprises a number of ribs 1 braced at 2, 3, and connected together by spar elements each formed from lower and upper rods 6, 7 braced at 8 and 9. Two such elements hinged at 13 are hinged to adjacent ribs at 12 and constitute a collapsible toggle, being shown extended at 15a, partly collapsed at 15b, and fully collapsed at 15c. The framework when extended is braced by wires 24. A fastening 16 at each hinge 13 engages automatically when the toggles are extended, and is releasable by pulling a cord 20 to collapse the toggle. Each cord 20 is attached to a line 21 extending to a loop 22 outside the wing through a seal 23, so that loop 22 may be pulled to release the toggles. An inflatable flexible skin 26 covers the framework. Partitions 30, 31 are secured to the skin adjacent the spar-like elements, and are apertured only to permit passage of the ribs and bracing wires. The inflating gas is admitted between the partitions by means not shown, and flows through these apertures to the remainder of the wing, setting up temporary pressure differentials across the partitions, which thus urge the toggles to the extended position, where they are automatically secured by fastenings 16. On deflation, cord 22 is pulled, releasing the fastenings, and reversed pressure differentials assist in collapsing the toggles. In a further embodiment, the wing is swept back, the ribs being staggered, and to allow the skin 26 to fold without tension stresses, the two elements of each toggle are of suitable unequal sizes. The pairs of diagonal bracing wires 24 are each replaced by a single pivoted diagonal rod. The wing may be made in two sections secured together at the aircraft's plane of symmetry, or may be in one piece extending from wing tip to wing tip, the wing being braced by wires extending from the undercarriage structure, as in Fig. 3 (not shown).

Title: Improvements in and relating to the automatic regulating of a periodic variation of a process variable
IPC: G05D11/13
Filed: 1960-08-12
Abstract: 949,199. Automatic control. HUTTENWERK OBERHAUSEN A. G. Aug. 12, 1960 [Sept. 11, 1959], No. 27964 /60. Heading G3R. In a system for automatically controlling a process variable subject to a periodic variation, measurement of the variable is stored and, after a time corresponding to one period minus the time lag of the control system, is introduced into the control system. In Fig. 1 a drum furnace 1, rotated about a horizontal axis by a motor 2, contains molten metal having a carbon content. A refining agent, e.g. oxygen, the flow of which is controlled by means 9, is supplied through nozzles (not shown) which dip below the level of the metal and the carbon monoxide produced is burnt by further oxygen supplied above the surface of the metal. Means 3 derive a signal representative of the carbon monoxide content of the exhause gases and this content is maintained at a desired value by applying the signal through a transformer 4, a controller 7, and an amplifier 8 to adjust means 9. The desired value is set by means of a signal generator 6 and a differential component of control is added by means 5. Irregularities in the furnace as it revolves cause a variation in the depth of immersion of the nozzles and the consequent effect on measuring device 3 is recorded on an endless magnetic tape recorder 15 driven in synchronism with furnace motor 2. By suitably positioning record and reproducer heads (not shown) on the recorder the recorded signal is applied to controller 7 after a delay corresponding to one furnace revolution less the time for an applied correction to become effective at measuring device 3. Since the last mentioned time lag is constant despite variations in the speed or rotation of the furnace, a motor 20, positioned by a followup servo-system in accordance with furnace speed, adjusts the length of tape loop between the record and reproducer heads. A positional follow-up signal produced by a signal generator 10 associated with means 9 is applied to the input of controller 7 through a differentiator 12 and also through recorder 15 to delay it by a time corresponding to one revolution of the furnace.

Abstract: 519,639. Prepayment mechanism for meters. METERS, Ltd., and BROWN, R. T. Sept. 26, 1938, No. 27976. [Class 27] Comprises coin - freed prepayment mechanism for a gas or like meter wherein manual manipulation of a handle or knob applies a force tending to open the gas valve. actual opening movement however not taking place until a predetermined movement of the quantity wheel, preceded by insertion of a coin, has taken place. In the construction shown the spindle a of the operating handle s carries a pin or lug c engaging a pin h on an arm or lever i loosely mounted on the spindle, the outer end of the arm having a pin j connected by a spring to an arm on the gas valve spindle (not shown). Thus, whenever the handle s is rotated the spring is tensioned and an opening force applied to the gas valve arm. When no prepayment has been made the gas valve is held closed by a cam k pivoted on the spindle a and controlled by the quantity wheel g. A Geneva stop device m on the cam k is connected by a pinion not shown to a wheel n fixed to. the quantity wheel. Thus, when a coin is inserted and the quantity wheel rotated the cam k is rotated and its outer end moves away from the gas valve arm allowing the valve to be fully opened by the spring connected to the pin j. The effect is that, although the movement of the cam k may be quite slow the valve makes a 'rapid full-opening movement.

[Class 38 (iv)] A.C. power of constant phase and frequency is supplied from commercial mains through a wound rotor type of A.C. motor, the elements of which are adjusted as required by space discharge devices sensitive to a change in phase and frequency between the load current and a standard source. Such a power supply may be provided for a facsimile or other telegraph system. Two systems are described. According to Fig. 1, vapour-filled discharge devices 14, 16 have anodes supplied from the load circuit and grids supplied through a phase adjuster 34 from a standard source 30 preferably in quadrature. Phase changes thus increase or decrease the mean current through a relay 38 in the anode circuit and energize appropriately the armature of a reversible motor 52 which adjusts a rotor 6 lying in the field of a stator supplied from the commercial source to maintain the phase constant. According to Fig. 2, the motor 6 and a constantly running motor M1 are coupled through a differential gear D with a D.C. series motor M1 When the anode current varies due to phase change or to frequency variation, the change in speed of the motor M1 causes movement of the rotor 6 to annul the change in phase and frequency. A D.C. grid bias may be introduced, variable by switch or potentiometer, to provide manual adjustment of phase and frequency.

Abstract: 735,463. Cathode-ray tubes. GENERAL ELECTRIC CO., Ltd. Nov. 6, 1953 [Nov. 7, 1952], No. 28124/52. Class 39 (1). A post-deflection accelerating field in a cathode-ray tube is produced by a helical conductive path of varying width along its length, formed on an insulating surface surrounding the path of the electron beam. The path is maintained at a positive potential and carries a direct current. The field equipotentials are made orthogonal to the electron beam over its range of deflection. The insulating surface may be conical, opening towards or away from the centre of deflection, or planar, extending at right-angles to the mean path of the beam. The planar surface is formed by an apertured disc. The insulating surface may precede the deflecting system, suitable screening ensuring that the accelerating field is produced only in the region between the deflecting system and the target. As shown, the helical path 9 is formed on the conical portion 2 of the envelope. At one end it is in contact with the anode coating 11, and at the other end with the aluminium coating 8 on the fluorescent target. A partspherical gauze may bound the helical path at the end opposite the target. The gauze is coated with carbon to inhibit secondary emission. The conductive path consists of a mixture of kaolin and graphite or lamp black. A coating is deposited on the insulating surface from a suspension in butyl acetate and nitrocellulose. A helical gap is then cut in the coating by a rotatable blade. As the blade rotates it is moved forward by a cam surface shaped to inpart the desired variation in the width of the helical path.

Abstract: 1,193,982. Self-adaptive automatic control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 20, 1967 [June 23, 1966], No.28324/67. Heading G3R. In a self-adaptive closed-loop control system for a process variable, an auxiliary positive feedback loop produces oscillation of the variable of limited amplitude and the frequency of oscillation determines the frequency of operation of a switch introducing a differential or integral component into the main control loop. As shown, a variable of a process 4 is stabilized by a negative feedback loop 1 including an amplifier 3 and members 2a, 2b which derive proportional and integral components respectively. An auxiliary, positive, feedback loop 6 including a high pass filter 10 and an amplifier 11 produces oscillation of the variable which is limited to a small amplitude by the characteristics of amplifier 3 the gain of which decreases if process gain increases. The frequency of this oscillation is a function of the process control time lag and pulses having this frequency are derived by a network 8 to control a monostable multi-vibrator 9 so that a switch S, which may be electronic, operates continuously with a mark-space ratio corresponding to the frequency. The consequent variation of the time during which an integral component is derived adjusts the response of the control system to suit any change of process control time lag. Member 2b may also introduce a differential component of control.
