Title: Improvements in or relating to a method of manufacturing electric discharge tubes
IPC: H01J5/24
Filed: 1950-07-13
Abstract: 676,054. Thermionic valves. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 13, 1950 [July 16, 1949], No. 17554/50. Class 39 (i). [Also in Group XI] In making a discharge tube comprising a cylindrical glass bulb without flange which centres the tube in its holder and has a locating member 41 on its periphery, the bulb is placed in a cold state on a plane glass base 28 through which contact pins connected to an electrode system are sealed, and of diameter equal to the outer diameter of the bulb, then the adjacent edges softened by heating but not melted and subsequently sealed together by mechanical pressure such that the shape and diameter of the bulb at the sealing area remains unaltered. The base with bulb on top are mounted in a lower holder 30 of a turret, then the holder raised so that the tube parts are secured also in an upper holder 29, both holders rotating at the same speed. After preheating the contacting edges are locally softened in turret positions 8, 9, 10 (none of the turret positions is shown), and pressed together in position 11 by rollers 40, 40<SP>1</SP>, inclined at 45 degrees, then after heated in position 12 and allowed to cool in positions 13-20. The temperature of the edges is kept below 900‹ C. and the sealing takes less than 15 seconds. The upper holder 29 may supply inert gas to the inside of the bulb to prevent flame combustion products acting on the electrode.

Title: Improvements in and relating to instruments for linear measurement and/or tolerance testing of workpieces
IPC: G01B5/08
Filed: 1956-06-07
Abstract: 814,822. Optical linear-dimension gauges. EBAUCHES S.A. June 7, 1956 [Sept. 26, 1955], No. 17568/56. Class 106 (2). A gauge for testing borehole diameters comprises a body 1, Fig. 1, with an eye piece 50, a head piece 5, Fig. 3, including a feeler 13 movable across the line of sight against the resistance of a disc-shaped braking plate spring 22, and apertures in the head piece 5, feeler 13, and plate spring 22 whereby the setting of the feeler can be read. The setting is determined by means of a transparent scale 18 secured to the feeler 13 and movable therewith relatively to a graticule 9 provided with a reference mark. The position of the graticule 9 can be set by adjusting screws. To measure the diameter of a bore hole the feeler member 13 is pushed into the head piece 5 and the head inserted in the bore in such a manner that the axis of the body 1 is inclined with respect to that of the bore in a plane containing the longitudinal axis of the feeler member 13 so as to space the member 13 away from the wall of the bore hole. By pushing a button 47, Fig. 1, a lever 45 displaces a sliding tube 39 which in turn causes an arm 32 to push the feeler 13 out of the head 5 and against the wall of the bore hole. The pressure on the button 47 is then released to permit the arm 32 and the sliding tube 39 to return to their original position under spring action. The body 1 is then swung until the medial plane of the feeler 13 is at right angles to the axis of the bore hole, a motion that causes the feeler 13 to be pushed inwards against the action of the braking spring to remain in the innermost position to which it has been displaced. After the measuring head has been removed from the bore hole and the eyepiece 50 applied to the eye, the eyepiece 50 is turned to adjust the distance between lens 48 and lens 49 until the position of the feeler can be read. The feeler 13 is in the form of a flat plate and the braking disc 22 has at least one rim of the opening therethrough bent up to bear resiliently against the feeler 13. Reference has been directed by the Comptroller to Specification 646,992.

Title: Improvements relating to extrusion presses
IPC: B29C48/10
Filed: 1956-06-07
Abstract: 793,497. Extrusion-machines. LONZAWERKE ELEKTROCHEMISCHE FABRIKEN GES. June 7, 1956 [June 8, 1955], No. 17618/56. Class 87(2). In an extrusion-machine having a pressing worm 3, Fig. 1, and a heated die head 1 a spring- loaded valve 7 is placed in the die head and is opened only when a certain pressure exists in in the chamber 4 behind the valve. When this pressure exists the plate springs 9 yield and the valve moves to the open position shown. The purpose of the valve is to keep a high pressure in the screw chamber 2, this high pressure resulting in a reverse " leak flow " of plasticized material back towards the hopper 2a, and this flow carries air bubbles back with it. Fig. 2 shows apparatus for extruding tubes, the core 22 being urged downwardly by springs 9 and upwardly by the pressure existing in space 4a. When the core rises an outlet gap 25 is formed between the lower face 7a of the core and the die body 21. Air may be blown into the extruded tube, through hollow core stem 23, to inflate it.
