Title: Improvements in or relating to methods and apparatus for sealing glass plates or shells to the main body of the envelope of an electron discharge device
IPC: H01J9/26
Filed: 1946-07-08
Abstract: 614,261. Cathode-ray tubes. CINEMATELEVISION, Ltd., and BARTLE, O. July 8, 1946, No. 20284. [Class 39 (i)] A method of sealing a plate or shell to the main envelope portion of an electron discharge device such as a cathode-ray tube comprises fitting the neck of the envelope over a collapsed jig, extending the jig so that it supports the plate or shell horizontally, and thereafter performing the sealing operation. The jig comprises three or more arms 4, Fig. 1, with adjustable extensions 5 the arms 4 being pivoted so that by moving a handle 7 in a slot 8 the arms can be collapsed or extended. The jig is mounted on a self-centering chuck 2 having three. arms 11 which are movable in a radial direction. In the sealing operation the neck of the envelope of the discharge tube is displaced upwardly so that the plate or shell is lifted by the envelope off the ends of the extension members 5 and the jaws 11 are then tightened to hold the envelope in this position. The unit is then rotated slowly, the parts to be sealed together are heated, and a roller or rollers is pressed down on the plate or shell until the latter is pressed down into contact with the top ends of the extensions 5 ; the speed of rotation may now be increased until the operation is completed. The invention may be applied to sealing a glass plate which may or may not carry the fluorescent screen, or a convex or concave glass shell for correcting optical distortion which may be spherical or aspherical in shape to the main envelope portion of a cathode ray tube, or to sealing a metal plate to form part of the wall of a cathode-ray tube of a type where the image is viewed or projected from the side of the fluorescent screen scanned by the electron beam.

Abstract: 704,073. Grinding fishing lines. HEDGE, M. K. Nov. 21, 1951 [Aug. 21, 1950], No. 20666/50. Class 60 [Also in Group XXV] A machine for smoothing a fishing line 29 by grinding comprises a tool 12 having a convex surface and arranged to rotate about an axis passing through the surface, and means for guiding the line so that it makes contact with the surface over a substantial length thereof. The tool is mounted on a central shaft 14 driven by a belt from an electric motor 15.. Two adjustably mounted sets of pulleys 17, 18 and two adjustably-loaded sets of jockey pulleys 21, 22 are provided to guide the line which is fed from a drum 30 to a drum 36 by being passed successively over the pulleys 17, 18, and alternately on each idle pass between these pulleys, over the pulleys 21, 22. The drum 30 and the pulleys 17, 18 are freely mounted on shafts which are rotated to reduce starting friction while the drum 36 is driven through a belt from an electric motor 27. The shaft 31 carrying the drums is mounted in adjustable bearings and rings 33 and 35 are arranged to guide the line between the drums and pulleys. The convex surface of the tool causes each pass of the line to move sideways and thereby rotate. Guides 44 prevent the line' from leaving the tool which is made of steel and may be covered with fine abrasive. Operation of either of two linked levers 41 applies brake pads to a drum 42 secured to the underside of the tool and actuates a switch 43 to de-energize the electric motors. Brushes 40 clean the line before it is wound on to the drum 36.

Abstract: 1,213,235. Sliding clasp fasteners. LIGHTNING FASTENERS Ltd. 8 May, 1968 [1 May, 1968], No. 20669/68. Heading B5A. [Also in Divisions E2 and H5] A method of manufacturing a stringer for a sliding clasp fastener, the stringer consisting of a carrier tape 15 and continuously connected coupling elements 10, comprises passing each element part way through the tape so that a portion, e.g. the coupling head 11, of each coupling element projects from one face of the tape. The elements are prevented from separating from the tape by widening the portions of the elements penetrating the tape. The portion of the coupling elements inserted through the tape may be either the coupling head 11 or the end 13 remote from the coupling head. The elements are widened by the application of pressure and/or heat. This may be done by means of a block and roller, or two rollers. The roller is designed to permit heating by the application of high frequency electrical energy. In addition the sliding clasp fastener having a stringer produced by this process is described together with a modification of this fastener in which the fastener is of the concealed type.
