Title: Improvements in or relating to method and apparatus for continuous casting of metal tubes
IPC: B22D11/00
Filed: 1966-06-23
Abstract: 1,138,072. Continuous casting-machines. PHELPS DODGE COPPER PRODUCTS CORP. 23 June, 1966 [1 July, 1965; 1 March, 1966], No. 28241/66. Heading B3F. In the continuous casting of metal tubes the centrally disposed mandrel 23 is initially raised out of the mould 22 so that a solid rod is cast, the mandrel being gradually lowered into the mould so that a tube 54 is eventually cast. The mandrel may be vibrated either together with or separately from the mould 22. Alternatively, the mandrel may be rotated (Fig. 5, not shown), either continuously in one direction to counteract the swirling effect of the molten metal as it flows from an induction coil 17 heated crucible 12, or oscillated rotatingly in each direction. The mould 22 includes a watercooling jacket 50, the water passing through the jacket to impinge on the tube 54 and run down into a quench chamber (55), (Fig. 2, not shown) through which the tube 54 is pulled by pinch rolls (61). The mandrel 23 is guided in the mould 22 by a guide bearing 20 and adjustment of the mandrel, angularly and laterally, can be achieved whilst casting is in process by adjusting bolts 38, 39 acting on another guide bearing 32 that guides a guide post 31 that is connected to the mandrel 23. The mandrel 23 may be water-cooled by internal tubes (92), (95), (Fig. 4, not shown), and a strain-measuring device 28 below the mandrel hoist 26 measures the drag on the mandrel by the withdrawing of the cast tube.

Title: Echo-sounding apparatus with steerable beam
Inventor: HOPKIN PETER ROY
IPC: G10K11/34
Filed: 1963-04-10
Abstract: 1,038,064. Echo-sounding. SMITHS INDUSTRIES Ltd. July 9, 1964 [April 10, 1963], No. 28395/64. Heading H4D. In a ship-borne pulse echosounder an electronic switching arrangement is used to sequentially energize individual transmitting transducers in a linear array to provide a steerable fanshaped beam. A steering signal voltage V is applied across a potential divider 11 having tapping points each connected to the cathode of a respective rectifier 12, and a ramp voltage from a generator 13 is applied to the anodes of the rectifiers 12. A rectifier 12 will conduct when the ramp voltage exceeds the tapped-off fraction of the voltage V applied to its cathode and there will therefore be phase lags between the commencement of conduction of the several rectifiers 12. The current pulse due to the start of conduction of each of the rectifiers 12 is amplified by an associated amplifier 16 to trigger a silicon controlled rectifier 17, thereby discharging a capacitor 18 through the energizing winding 19 of an individual transmitting magnetostrictive transducer. The transmission of the sound energy pulse is initiated by a device 14 triggering the ramp generator 13, the direction of the plane of the fan-shaped beam being determined by the phase lag between the energizations of the several transducer windings 19, which phase lag is controlled by the magnitude of the steering voltage V. A damped pendulum may be used to generate a steering voltage V dependent on the heel angle of the ship so as to maintain the direction of transmission of the beam vertically downwards irrespective of rolling of the ship, or a bias voltage may be applied in addition to the voltage V in order to maintain some other direction of transmission. Alternatively, or in addition, the voltage V may be made periodic to permit repeated scanning of the beam. In modifications, the rectifiers 12 may be reversed in polarity and the ramp voltage may decrease with time instead of increasing, or the rectifiers 12 may be replaced by other forms of voltage comparator, e.g. ones comparing the sum of the applied fraction of the steering voltage V and the ramp voltage with a given voltage.

Title: Improvements in and relating to lighting apparatus for gas cooker burners
IPC: F24C3/10
Filed: 1947-10-24
Abstract: 651,469. Lighting burners. CERNE, I. Oct. 24, 1947, No. 28510. [Class 75(iii)] [Also in Group XXIX] In lighting apparatus for gas cookers in which any one of a number of main burners 2, Fig. 1, may be lighted from a single permanent flame 13 by means of a lighting jet which by means of a " combination " valve 20 is supplied with gas whenever the burner in question is turned on, the said " combination" valve provides for the gas supply to the burner and to the lighting jet and also controls the size of the jet and main burner flames. Gas is supplied from a manifold to each of four gas burners 2, Fig. 1, through a pipe 5 controlled by a' valve 20 which also controls the supply to a lighting tube 15, 16, 17 or 18 with which each burner 2 is associated. Gas issuing from any of the lighting tubes is ignited by the permanent flame 13 controlled by a valve 21, and a jet-flame is directed towards and ignites the associated burner 2. The flame 13 and valve 21 may be dispensed with, a permanent flame being provided at the outlet of one of the lighting tubes 15 to 18, which flame is extended into a jet when the valve 20 controlling the associated burner is turned on. Alternatively the lighting tubes 15, 16 and 17 may be combined in a single tube having three outlets radiating jets which are ignited by a permanent flame from the lighting tube 18. A valve 20 for controlling a lighting tube providing a small permanent flame may comprise a rotary plug 54, Fig. 2, having passages 55, 56 for connecting an inlet 24 with outlets 52, 53 leading, respectively, to a lighting tube and its associated burner. At start the plug 54 is rotated so that a narrow channel 59<SP>1</SP>, Fig. 3d, leading from the passage 56 is aligned with the outlet 53 to permit a small gas flow to the lighting tube where it is ignited. On continued rotation of the plug 54 the main outlet of the passage 56 is aligned with the outlet 53 to produce a jet igniting a small gas flow at the main burner, supplied through a narrow slot 58', Fig. 3c, then aligned with the outlet 52. The burner flame is increased to a maximum by further rotation of the plug to align the main outlet of the passage 55 with the outlet 52, whilst at the same time the gas supply to the lighting tube is reduced, when a narrow channel 59 leading from the passage 56 is aligned with the outlet 53, to provide a small permanent flame. The size of the main burner flame may be controlled by further rotation of the plug 54 to adjust, with respect to the outlet 52, a tapering channel 58 leading from the passage 55.

Abstract: 773,484. Method and apparatus for producing originals for preparing intaglio plates. METTENHEIMER, G. W. Oct. 7, 1955 [Oct. 9, 1954], No. 28702/55. Class 98(2) To improve richness of tone of intaglio reproductions of a half-tone diapositive exposure is effected through the diapositive, a gravure screen and a transparent foil in that order on to a light sensitive surface, and then a 'second exposure is made through the screen alone in contact with the light sensitive surface and without lateral displacement therefrom, the emulsion side of the diapositive and the dot side .of the screen being placed away from the exposing light. The exposed surface may then be developed and contactprinted to make a diapositive for preparing a printing plate. In apparatus for the purpose an open frame 1 is provided with two longitudinal clamping strips 4 engaging recesses 2 to secure a gravure screen 14 to the frame, and a plate 8 fitting within the frame has bevelled parts 11 having an adhesive coating for temporary attachment of a sensitized film 12 thereto. A transparent (spacing), foil 13 is placed over the sensitized film 12 and the plate 8 assembly is inserted into the frame 1 to make contact between the foil and the gravure screen carried by the frame, a diapositive 18 is placed on the gravure screen and the whole is then arranged in a reproduction cassette having a vacuum operated device, for the first exposure in which, because of the spacing foil, no dots may be exposed from maximum image depth portions of the diapositive. For the second exposure plate 8 is taken out of the frame 1 for removal of the foil 13, the diapositive 18 is also removed, and the plate 8 is re-inserted to place the sensitized film against the gravure screen, registration being maintained by an interfitting arrangement of pins 10 carried by the plate 8 and bores 7 in transverse members 5 of the frame 1. The second exposure produces or completes the screen network for eventual support of the doctor blade.
