The guide pulley is under the influence of a restoring spring which is in the form of a spiral spring 8 and the spring force of which is transmitted to the guide pulley by means of a tension cord 20 adapted to be wound about a spring housing 9 rotatable about a non-rotatable pivot member, the spiral spring being secured at its inner end to the pivot member of the spring housing and at its outer end to the spring housing. The outer periphery of the spring housing comprises a spiral groove 17 for the tension cord. With appropriate dimensioning of the spiral groove on, the spring housing the restoring force on the pulley may be kept constant over the entire pulled out length. The non-rotatable pivot member may also comprise a profiled extension with a supporting roller 13 which rolls along an associated track. Arranged on the right hand end of the housing box is a detent device 25 into which the transverse pin 24 of the spring arm 23 locks after sliding over the inclined surface 27. In this position return of the guide pulley is impossible. However, if the hand piece is subsequently pulled, the pin is disengaged and the restoring spring can carry out its action. In an embodiment, the guide pulley and the spring housing are separate from each other. (For Figures see next page)

IPC: C03C1/00
Filed: 1916-06-29
Abstract: 101,685. Strandh, H. I. F. May 23, 1916, [Convention date]. Production of metal.-In manufacturing glass, particularly when the alkalis are added as sulphates, the batch mixture is divided into two portions, which are placed in the furnace separately, so that the first portion, which contains alkaline sulphates, silica, and carbonaceous matter, is melted before the second portion, containing, say, compounds of calcium and silica, is added. The alkaline sulphate is converted into silicate during the melting of the first portion, and the remaining portion is then added. In a modified method, the different portions of the batch may be placed in different layers or in different parts of the furnace and be heated all at one time. The least fusible of the constituents of the batch are preferably placed as a bottom layer in order to protect the furnace material, and the most easily fusible materials are placed near the furnace walls where the temperature is lowest. Calcium carbonate, arsenious acid, or other gas-pro. ducing substance may be added during the later stages of the melting to cause the mass to be stirred by the escaping gases.

Abstract: 743,796. Colour television tubes. GENERAL ELECTRIC CO. April 9, 1953 [April 12, 1952], No. 9667/53. Class 39 (1). In a colour television receiver of the reflection type the phosphor screen comprises an apertured plate 23, Fig. 1, of insulating material, e.g. organic plastic or glass, with apertures 24 arranged in concentric arcs, a thin layer of conductive material on the surface of the plate 23 remote from the gun and phosphor zones concentric with and between the rows of apertures. Specific materials for the apertured plate may be " photoform " glass, and a mixture of polyvinyl alcohol and potassium dichromate. The apertured electrode is made by exposing portions of it to ultra-violet or visible light, baking it and then etching with a bath of hydrofluoric acid which preferentially etches the previously exposed portions. In one particular process the plate 23 is covered with an opaque member 31, Fig. 4, with arcuate slots having a common centre of curvature 32 and corresponding to the desired apertures to be produced, the correct slanted axes of the apertures being obtained by placing the U.V. source 33 at the same point as the virtual beam source 22 in the completed tube. The entire arrangement is enclosed in a medium having the same refractive index for ultraviolet light as member 23. The preferential etching is stated to produce conical apertures 24, Fig. 1. An aluminium coating may be formed on the side of the member 23 to face reflector 29, and preferably on the other side as well, as by immersing in a bath. The tricolour phosphors are then deposited on the side adjacent reflector 29 in arcuate strips between and concentric with the arcuate slots, preferably by a printing process. The apertured screen 23 and reflector 29 are held in spaced relation by spacers 36, 37 of semiconductive glass, conductive clamping plate 38 and U-shaped clamps 35, 39 of which one is disposed at each corner. Reflector 29 is a transparent sheet with a transparent electrically conductive coating 30.
