Title: Improvements in methods and apparatus for the manufacture of tubes made of a fusiblematerial which can be drawn out, more particularly of glass tubes
IPC: C03B17/04
Filed: 1928-11-08
Abstract: 300,646. Favre, P. A., (Assignees of Blum, P.). Nov. 17, 1927, [Convention date]. Drawing ; forming glass tubes.-In a method of making tubing, a glass cylinder with an axial bore is heated until it is plastic, and is then drawn in the direction of its length to form tubing of the required diameter. The cylinder a, Fig. 1, is threaded on to a metal former b consisting of a tube which terminates in a bulbous enlargement b<1>. The lower end of the cylinder is heated by suitable means, such as burners c, until the glass melts and flows by its own weight around the bulb b<1>, as shown in Fig. 4. A tubular bait d is stuck on to the glass and is drawn downwards by suitable apparatus, such as opposed endless belts e, and the drawing is continued at such a speed that the glass drawn away from the bulb b<1> forms tubing of the required diameter. As the hot glass is drawn away, the cylinder a slips downwards and is progressively melted. As the tubing leaves the drawing-belts, it is notched at intervals by any suitable means, and an oscillating member breaks off the lowermost length and deflects it into a shoot. Means are provided for bringing a new cylinder into place above the burner when one is exhausted.

Abstract: 1,090,406. Electron multipliers; image converter tubes. MULLARD Ltd. June 25, 1964 [Aug. 19, 1963; Sept. 18, 1963], Nos. 32722/63 and 36758/63. Heading H1D. In an electron image intensifier comprising a matrix formed with an array of elongated channels having resistive and secondary-electron emissive surfaces extending between conductive input and output faces E 1 , E 2  of the matrix, photo-emissive surface areas are formed on the input face of the matrix or inside the channels thereof but extending to and contacting the input face. Electrons emitted by a photoemissive layer Pi on the input face are drawn into the channels by the accelerating field between E 1  and E 2 , but, if necessary, a transparent electron-reflecting electrode may be provided on the adjacent envelope wall. The input electrode E 1 ' may be light-reflective or transparent. Photo-emissive areas Pc may be formed inside the channels along 20% of their length, or along their full length if a material which is also secondary-electron-emissive is used. The matrix may be formed by glass tubes T 1 , T 2  sealed together with a transparent glaze G having a lower refractive index than the glass of the tubes, whereby light entering the tube walls may be subject to multiple internal reflections at least some of which may cause photo-emission, thus providing greater efficiency without loss of resolution. Alternatively, the sealing glaze may be opaque. The image intensifier may be manufactured or modified as described in Specifications 1,064,072; 1,064,073; 1,064,074; and 1,064,076. The matrix may be of glass and the electrodes E 1 , Eg and photoemissive areas of tin oxide or chromium, and antimony, respectively. After assembly in an envelope, the matrix is treated with caesium vapour to activate the photo-emissive areas and render the exposed channel surfaces resistive and secondary-emissive.
