Title: Improvements in and relating to thermosetting moulding compositions
IPC: C08L61/22
Filed: 1947-07-02
Abstract: Thermosetting moulding compositions suitable for moulding high-frequency insulators, valve bases, coil housings, television parts, &c., comprise a melamine-formaldehyde resin, an aniline-melamine-formaldehyde resin, and silica flour; the constituents are preferably mixed in the ratios 20 : 20 : and 60 by weight.  A small proportion of an aniline-cresol-formaldehyde resin may be included in the composition, and also cotton flock, glass fibres and mica.  Tables are given in the Specification of compositions containing the above ingredients in various proportions and of the variation in flexural strength, shrinkage, and arc resistance of the moulded products obtained therefrom. The aniline-melamine-formaldehyde resin has a mol. ratio of aniline to melamine of at least 2 1/2 to 1 and is prepared by adjusting a mixture of 890 parts melamine and 1710 parts 37 per cent formaldehyde to a pH of 8.5, heating until slightly hydrophobic, adjusting the pH to 10, concentrating for 1 hour under 60 cm. pressure, adding 1970 parts aniline, and further concentrating under 71 cm. pressure at 88-130 DEG  C.

Title: Index signal generating device
IPC: H04N9/24
Filed: 1959-05-22
Abstract: 926,182. Colour television tubes. D. E. SUNSTEIN. May 22, 1959, No. 1759/59. Class 39 (1). [Also in Group XL (b)] In a colour television receiver employing a cathode-ray tube with a screen, Fig. 1, made up of repeating groups 26 of red, green and blue colour-reproducing strips and which incorporates indexing strips 30 to indicate the instantaneous beam position during scanning the indexing strips repeat at a rate which is a non- integral number greater than 1 times the rate at which the colour groups repeat. The rate may, for example, be 1¢, 2¢, 3¢ &c. times the colour group rate, the preferred rate, which is illustrated in Fig. 1, being 2¢ times. The Specification shows, with reference to Figs. 2-5 (not shown), that the resulting indexing signal obtained from strips 30 is not subject to phase errors in accordance with the modulation of the scanning beam to reproduce different colours. In order to produce an indexing signal at the frequency of scanning the colour groups it becomes necessary to divide down the frequency of the original indexing signal. This will produce in the derived signal an ambiguous phase relationship with the colour groups. To avoid this, an edge portion of the tube screen, Fig. 6, which is scanned before the main part of the screen, is provided with further indexing strips 10 which are positioned to form a continuous series with strips 30 but which are spaced so as to produce an indexing signal at a frequency equal to or a subharmonic of the frequency of scanning the colour groups. As illustrated in Fig. 6, strips 60 occur at onehalf the rate of the colour groups. The signal from strips 60 is in unambiguous phase relationship with the colour groups and may be employed to establish the correct phase relationship in the frequency division operation performed on the signal from strips 30 (see Group XL (b)). Specifications 926,183 and 926,184 are referred to.

Title: Improvements in or relating to apparatus and methods for welding tubes or electric cable sheaths
Inventor: DONELAN JAMES ARTHUR
IPC: B23K9/025
Filed: 1959-05-25
Abstract: 888,097. Making tubes and electric conductors; welding by fusion; skelping by rolls or dies. PIRELLI-GENERAL CABLE WORKS Ltd. May 17, 1960 [May 25, 1959], No. 17709/59. Classes 83 (2) and 83 (4). In apparatus for arc-welding the longitudinal seam of a tube or cable sheath formed by bending metal strip, the welding torch 5 and one or more sets of forming rolls 9 or dies through which the strip 10 passes are mounted on a carriage 2 movable in the direction of the seam, and a device 23, released when the welding arc is extinguished, locks the carriage 2 in the normal welding position. The torch 5 and rolls 12 and 13 are mounted on a sub-carriage 6 movable on the carriage 2 manually or by a piston in a cylinder 8. When the welding current is switched off or the arc is extinguished, a valve 31 is actuated to release the locking device 23 and the capstan 14 on which the welded cable is wound is braked. As the capstan 4 slows to a stop the pull of the strip 10 on the forming rolls 9 and/or a separate power device moves the carriage 2. The subcarriage 6 may be moved so that the torch 5 overlaps the end of the weld. When the capstan 14 is restarted, the carriage 2 is pulled by the strip 10 until an abutment 25 engages an adjustable stop 24 and actuates a limit switch 27. The welding current is thereupon connected up and the arc is struck by a highfrequency current. Subsequently a piston and cylinder arrangement 18 is used to return the carriage 2 to be locked in its normal position by the device 23. In a modification, the forward movement of the carriage is terminated and the arc is struck under the control of a tachometer-generator driven off the tube and having output terminals connected to the welding torch switching mechanism. This generator may also be used to control the release of the locking device 23. Specification 741,303 is referred to.

Title: Machine for sealing an aperture in a container wall
IPC: B65B7/28
Filed: 1963-05-06
Abstract: 1,047,582. Stoppering. AMERICAN CAN CO. May 6, 1963 [May 11, 1962], No. 17793/63. Heading B8T. In a machine for sealing an aperture in an aerosol container by inserting a plug therein, the container is supported horizontally on a reciprocal cradle 24 which is then moved towards a sealing head 21 to urge the container against the head with its aperture aligned with a plug guiding channel 22. The plug is cut from a string of resilient material J fed through a member 142 and into the path of a reciprocal shear member and slide 26. The end of the string is received in a hole 69 of the slide whereupon the slide moves horizontally in a slideway 60 to cut off the plug and bring it into alignment with the channel 22. A reciprocal plunger 27 is then driven to push the plug from the slide into the channel and to hold it therein whilst vacuumizing and pressurizing of the propellant space A of the container is effected via the channel 22, passage 98 and conduit 99 connected through valves with vacuum and pressure lines 101 and 102 respectively. During the vacuumizing &c. operations the slide is moved back to its original position, a slot 70 in the slide enabling it to be removed from engagement with a reduced part 96 of the plunger. The plunger 27 is then moved to push the plug further through the channel 22 and into the container aperture. Near the end of this plunger stroke the string J is urged forwardly an amount equal to a plug length into the hole of the slide in preparation for a further cycle of operations. The container cradle is moved away from the sealing head and the plunger removed from the channel 22 and an aligned opening 84 in a plate 31 on which the head and slide are mounted. Actuation of all the reciprocatory parts is preferably by fluid pressure devices of the piston and cylinder type operated in timed relation through a timing mechanism comprising a motor-driven camshaft; the latter carries a number of edge cams operating switches controlling fluid flow to the various devices. As shown, piston and cylinder devices 46 and 74 drive the cradle and slide respectively; the plunger is driven by two such devices 93 and 86, the former providing the first movement of the plunger to the position shown in Fig. 6 (not shown), and the latter to complete the plug sealing operation. The plunger drive includes a yoke 153, Fig. 5 (not shown), which operates during the latter part of the plunger stroke to move the string J forwardly into the slide. The string passes through the member 142 and a slotted sleeve 141 on which a slider 147 with string gripping fingers 151 is mounted. A spring urges the slider outwardly and during such movement the fingers slide about the string, but on forward movement of the slider by the yoke the string is urged forwardly.
