Patent GB-439947-A (GB)
IPC: G03C7/14
Abstract: 439,947. Colour photography. GROVES, W. W., 30, Southampton Buildings, Chancery Lane, London.-(I. G. Farbenindustrie Akt.- Ges. ; Frankfort-on-Main, Germany) May 11, 1934, No. 14284. [Class 98 (ii)] In printing from a lenticular colour-record original onto a lenticular sensitive film, moirÚ is avoided by using a sensitive film in which the junctions between adjacent lenticles are either sharp angles A, Fig. 1, or concave bridges BC, Fig. 2, of breadth not exceeding about 7 per cent that of a lenticle, and the printing is effected without the use of other means for avoiding moirÚ. The films may be selected by microscopic examination of a filter or diaphragm viewed through a junction between the lenticles, and this may be done before the films are coated with emulsion. When films are embossed by casting them on an engraved support as in Specification 341,948, only the first film cast need be examined, and if the film is unsatisfactory another casting support must be made and tested, and the process repeated if necessary until a satisfactory one is obtained.

Title: Method for the Automatic Control and Regulation of the Basic-Oxygen Process.
IPC: C21C5/30
Filed: 1966-10-03
Abstract: 1,167,873. Automatic control of the basic oxygen refining process. FRIED. KRUPP G.m.b.H., and SIEMENS & HALSKE A. G. Oct. 3, 1966 [Oct. 4, 1965], No. 44060/66. Heading G3R. An oxygen blowing process for refining molten carbon-containing metals is effected in an optimum manner by using an electronic computer 16 to automatically regulate the position of the lance 1 and the setting of the valve 23 controlling the oxygen flow to the converter 3, the computer comparing the actual value of a characteristic of the metallurgical course of the process with a set value of that characteristic and comparing the actual value of a characteristic of the waste gas flow with a set value of that characteristic. In the described embodiment the characteristic of the process is the distribution of oxygen O c  between the bath of metal and slag and the waste gas, the value O c  being calculated by the computer using a known equation, measured values of flow of waste gas and flow of oxygen and analysis of the waste gas. The characteristic of the waste gas flow is the waste gas heat flow Q which is calculated by the computer using a known equation, the oxygen distribution O c , the flow of oxygen and calculated values of carbon monoxide and carbon dioxide in the waste gas. Other characteristics of the waste gas flow suitable for use are the speed of combustion of the carbon in the metal, the chemical composition of the gas, or the temperature, the steam pressure or the steam flow in the waste gas cooler. The set value of the process characteristic may be altered during blowing in dependence on time and/or at least one variable, e.g. the flow of oxygen, the temperature of the bath, the conductivity between the lance and the bath or the converter noise. The alteration may be effected empirically on the basis of desirable values known from experience. The set value of the waste gas characteristic may be varied with time and/or the flow of oxygen and/or bath temperature and/or the progress of the combustion of carbon. In the described embodiment calculated actual values of O c  and Q are compared with set values to derive error signals which are respectively fed to PID controllers 34, 35 determining the lance position (X) and the oxygen flow dOB/dt these parameters being controlled to maintain the actual values equal to the set values. The output from controller 35 is also fed to a divider 36 supplied with the blowing ratio B obtained from controller 34, the member 36 relating the valves B, dOB/ dt and X by a known equation so that variations of oxygen flow (dOB/dt) cause corresponding variations in lance position (X) to ensure that the oxygen distribution (O c ) is maintained at the value existing before the oxygen flow was varied.

A centripetal plasticizer for use in association with extrusion or injection moulding machines comprises rotors 12, 13 defining a shear gap 19, whose rotational axes are non-coaxial. As shown, rotor 13 is driven by a motor 40 and its drive shaft 17 incorporates a helical flight 18 which delivers material from a hopper 14 to the shear gap by flow thereof around the periphery of the rotor. Rotor 12 is driven by a motor 43 via a gear 41 integral with rotor shaft 21, this shaft incorporating a passageway 23 for delivery of the plasticized material. Rotors 12 and 13 are rotated in the same direction and preferably at the same speed, the shear force being proportional to the radial distance between the rotor axes and the angular velocity of the rotors and inversely proportional to the axial distance between the opposed faces of the rotors. The shear effect is modified by introducing a difference in the angular velocities of the rotors. In modifications, flight 18 may be dispensed with, feed of material being direct to the shear gap, and a single motor only may be used.

In a Joule Thompson cooling apparatus in which a gas is liquefied to cool a load, the compressed gas supply to the Joule Thompson nozzle is modulated by valve control. As illustrated in Fig. 1, a control unit 95 is included in the line between a bottle of compressed gas and the Joule Thompson apparatus. A valve 107 is influenced by springs 100 and 104, downstream gas pressure on a face 97, and a bellows 99 which is connected with a bulb 110 in the Joule Thompson cooler and towards which the nozzle is directed. In the embodiment of Fig. 2 a metal rod 115 is so arranged with respect to the nozzle 83 and has such a coefficient of expansion relative to the remainder of the cooler that rising liquid level in the latter causes the flow cross-section of the nozzle to be reduced. In a modification, Fig. 3 (not shown), a bellows (120) in the cooler contracts with rising liquid level to operate a baffle (123) to reduce the flow crosssection of the nozzle. The Joule Thompson cooler together with its flow control may be incorporated in a cold gas engine as a second cooling stage, Fig. 4 (not shown).

A signal generator, e.g. a V.H.F./U.H.F. beacon for emitting a distress signal is arranged to produce an output signal consisting of two interlaced signals comprising two different but related carrier frequencies. This enables the beacon to be used with receiving equipment which operates on one or other of the two frequencies. As shown, a beacon comprises a crystal-controlled oscillator 1 producing a carrier frequency of 121À5 Mc/s. which is applied via an amplifier 2 to driver and power amplifier stages 3, 4 where it is amplitude modulated by a 1 kc./s. signal supplied via amplifier 5 from oscillator 6. This modulated carrier wave is supplied to serially connected filters 7, 8, filter 7 rejecting the second harmonic of the carrier wave and filter 8 rejecting the carrier wave. A frequency-doubler circuit including a varactor diode 10 is connected to the junction of filters 7, 8. A generator 11 produces a ¢ c./s. square wave which operates a transistor switch 12 so that a bias supply at 13 is applied for periods of one second with intervals of one second to a diode 9 connected across filters 7, 8.

Both nut and sleeve may be provided with mutually cooperating longitudinal ribs 20 to prevent relative rotation between nut and sleeve when the bolt is tightened. In order to prevent the nut and sleeve from rotating in the hole, the edges of the sleeve adjacent a longitudinal slot 18, see Fig. 3, may be bent outwardly to form lips 21 which engage the wall of the hole when the bolt is tightened. Alternatively, outwardly directed tongues may be formed at a rear edge, as viewed in the direction of rotation, adjacent to slot 18.
