Title: Automatic buffing machine
Inventor: HAWKINSON EARLE W
IPC: B29B17/02
Filed: 1958-09-16
Abstract: 849,139. Rasping tyres. HAWKINSON CO., P. E. Sept. 16, 1958, No. 29633/58. Class 31(1). A tyre buffing or rasping machine comprises in combination a base 1, a vertical column 4 extending therefrom at the top of which is mounted a horizontal slide 7 bearing a motordriven shaft and hub 8 on which a wheel 9 with the tyre to be treated is carried, a power-operated second horizontal slide 17 moving in guides 15 secured to the base normal to the direction of movement of the slide 7 and having mounted thereon a pivot 23 which carries a third horizontallymovable slide 33, in a guideway 25 forming an adjustable radial arm on which a buffing-wheel or rasp 44 is carried and which is capable of an automatic power-operated oscillatory movement across the tread of the tyre, the feed, or movement of the buffing wheel towards the centre of the wheel 9, being controlled automatically by means responsive to the oscillatory movement of the guide 25 to cause a step-by-step adjustment of radius of the buffing arc. The slide 7 is manually adjustable by a screw 13 and wheel 14, and the slide 17 is movable by a screwed shaft driven by a motor 22 to bring the tyre and buffing-wheel 44 initially into a buffing position, adjustment of the slide 7 being generally for buffing a shoulder-portion of the tyre. The oscillatory movement of the guideway 25 is effected by a fluid-pressure cylinder 52 and plunger-rod 54 pivotally secured at its outer end to a bracket 55 depending from the guideway and radially spaced from the supporting pivot sleeve 23. The fluid pressure system is operated by a pump 59 drawing fluid from a tank 59a and comprises a reversing valve 60 and pressureregulating and metering valves 62, 61, respectively. Reciprocating action of the rod 54 is effected by reversing switches engaged by a replaceable trip-bar which is changed to vary the length of stroke of the plunger. Further switches are provided in a control-box 72 to control the motors 22, 11 and 59b and to render the pressure-fluid system inoperative so that the oscillatory movement of the buffing-arm may be made manually. The buffing wheel feed is automatically advanced during the oscillatory movements of the slide 33 by a cam element 82 extending upwardly from the slide 17 and radially-spaced from the pivot 18, also secured to the slide 17. During the swing of the guideway 25 over the cam support 81 a push-rod 83 engages a rocker 85, 91 carrying a ratchet mechanism 92, 96 whereby a screwed shaft 36 is rotated unidirectionally to move the slide 33 with the buffing-wheel and its drive horizontally towards the pivotal axis. The automatic feed may be rendered inoperative by turning a knurled knob 95 until the pawl-spring 97 is moved past its dead-centre position and thus holds the pawl disengaged. Manual adjustment of the feed may be effected by a hand wheel 42 and chain 38 which drives a sprocket mounted on the shaft 36. U.S.A. Specification 2,787,089 is referred to.

Title: Improvements in or relating to methods of manufacturing Dispenser Cathodes
IPC: H01J9/04
Filed: 1967-06-28
Abstract: 1,178,045. Cathode materials and processing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 June, 1967 [1 July, 1966], No. 29776/67. Heading H1D. In a method of manufacturing a dispenser cathode comprising a porous sintered tungsten body impregnated with barium-calcium-aluminate, the barium and calcium carbonates and alumina constitutents required for forming the aluminate are obtained by co-precipitation and are mixed with a soluble carbon-containing compound, preferably sugar, and a binder. A layer of this mixture is then brought into contact with the surface of a porous body to be impregnated and the body and layer are gradually heated in a hydrogen atmosphere, e.g. at 1000‹ C, until the carbonates are dissociated and all the developed gases have been removed, the temperature is then gradually increased to 1400‹ C. to form the aluminate and reduce any tungsten oxide formed, after which the temperature is then further increased to above 1600‹ C. to melt the aluminate which is then absorbed in the porous body, and the impregnated bodies are cooled. Preferably the coprecipitated mixture consists of 5BaC0 3 , 3CaC0 3  and 2Al 2 O 3  suspended in nitrocellulose with 3% by weight of sugar added. A continuous series of unimpregnated bodies may be passed at a fixed rate through a tunnel furnace 5, which is divided into zones of different temperature and length, as shown in Fig. 2b, and a stream of hydrogen is passed through the furnace in the opposite direction to that in which the tungsten bodies are travelling. The layer 2 of the co-precipitated mixture may be formed on a non-porous tungsten substrate 1 and shaped or curved rods or discs of sintered porous tungsten are placed on top of layer 2, or the aluminate constituents mixture may be applied directly to the sintered tungsten surfaces by spraying, immersion, pouring or by cataphoresis. Dimensions of an example of an impregnated tablet, which may be used in an indirectly heated cathode, are given.
