Patent GB-384351-A (GB)
Title: An improved method of producing metal vapour in vacuum or gas-filled discharge tubes
IPC: H01J9/04
Filed: 1931-07-15
Abstract: In the production of highly emissive cathodes in evacuated or gas-filled discharge or like tubes, the alumino-thermic reaction is performed outside the final vacuum tube in a separate vacuum chamber. For example, barium oxide is mixed with aluminium or silicon powder, and caused to react in vacuo, the product being stored in paraffin wax or other suitable protective until required.  Or magnesium may be used as reducing agent, and any unchanged magnesium may be evaporated out of the reaction product, but a trace left therein serves to bind any residual gas in the final vacuum tube, so that the barium is then vaporized in a perfect vacuum.  The barium may be replaced by any other suitable metal, such as calcium, strontium, beryllium, or caesium; in the production of beryllium, potassium may be used as reducing agent.

Patent GB-1047089-A (GB)
Title: New anthrapyridone pigments
Inventor: COOPER ALBERT CHARLES
IPC: C09B5/00
Filed: 1964-05-15
Abstract: The invention comprises anthrapyridone pigments of the formula <FORM:1047089/C4-C5/1> wherein R is H, alkyl, or cycloalkyl, X is H, acetyl or carboalkoxy and an optionally substituted g -quinolone residue is attached to the anthrapyridone ring in the 5:6- or 8:9-positions, the N of the quinolone being attached in the 6- or 8-position. The pigments may be prepared by ring-closing an anthrapyridone of the formula <FORM:1047089/C4-C5/2> wherein one of A1 and A11 is H, the other an optionally substituted 2-carboxy-anilino group, e.g. by treating with chlorosulphonic acid optionally in the presence of H2SO4, or the -COOH group may be converted to -COCl and the acid chloride heated in o-dichlorobenzene or, again, by heating with benzoyl chloride in o-dichlorobenzene. The alkyl group R and the alkoxy of X preferably contain 1-4 C atoms. The substituents in the quinolone residue may be halogen atoms or carboxylic acid groups.  The pigments may be employed as dry powders to colour rubber, synthetic textiles of polyvinyl chloride, polyethylene or cellulose acetate, paints or printing inks, for the mass-coloration of textile materials of viscose, cellulose acetate, polyacrylonitrile, polyamides, polyesters and polyolefins and as aqueous dispersions for emulsion paints, wallpaper and flushing into paint and lithographic vehicles.

Title: Improvements in or relating to the treatment of wood, and like porous material
IPC: B27K3/02
Filed: 1925-08-17
Abstract: 265,643. Smith, M., and Phipps, P. Aug. 17, 1925. Wood, treating with liquids and gases.-Wood, particularly that used in the manufacture of pencils, is softened and stained by impregnating it with the vapour of softening media, which are preferably of an oleaginous nature, by the following process. The wood is first dried, if necessary, then subjected to the action of the softening medium in liquid form, preferably in a vacuum, and finally heated to a temperature sufficient to cause the softening medium to vaporize and thereby penetrate the wood completely. As shown in Figs. 1 and 2, wooden slats, delivered from a hopper 2, are carried by a conveyer 3 through a long drying chamber 1, to which air, heated by passage through a chamber 4 heated by electric or other suitable means, is supplied by a fan 5. Preferably the temperature of the air when it enters the chamber 1 is 220-260‹ F. From the chamber 1, the dried wood is fed into an impregnating chamber and there subjected, preferably under vacuum, to the action of the softening medium, which may comprise a soap solution, an 18 per cent emulsion in water of Turkey red oil. or other oil emulsion. Finally the slats are transferred to a hot air chamber similar to the chamber 1, and heated to a comparatively high temperature to vaporize the softening medium, which thereby penetrates the wood completely. The process prevents subsequent warping of the wood, and the treated wood takes glue readily.

Title: Mastic applicator and finishing tool
IPC: E04F21/08
Filed: 1956-07-05
Abstract: <PICT:0805967/III/1> <PICT:0805967/III/2> In a mastic applicator and finishing tool comprising a tool body A movable over a surface 39 the body has a leading end and a trailing end, a mastic receiving recess A1 having an opening 5 through which the mastic is moved and a trowelling bar L forming an edge for the opening 5 and having a concave edge facing the surface 39.  The two ends of the bar L form two points of support between the body A and the surface 39 and a third point of support is positioned adjacent the leading edge of the body so that the tool body can accommodate itself to any irregularities in the surface.  This third point of support is formed by rollers 55 mounted on the ends of a lever V which is pivoted to a fulcrum plate C secured to the body A.  The body A comprises side walls 1, 2, an arcuate trailing end wall 4, a rigid bottom wall 3 in which the opening 5 is formed and a plate B fulcrumed at 7 to the wall 3 for forcing mastic T from the recess A1 out through the opening 5.  Coil springs D retain the plate B in its normal position. The trowelling bar L is flexible and is carried in a groove 51 formed in a flexible guide K.  As the bar L becomes worn it is advanced by screws 52.  Wear shoes N are secured to members M fixed to the sides 1, 2 of the body A.  The wear shoes extend under the flexible guide K for holding it against accidental removal.  When using the device, the mastic T is fed into the recess A1 through the opening 5 and the tool is applied to the wall surface 39, as shown in Fig. 2.  The operator presses on a handle F for moving the mastic pressing plate B down into the recess A1 against the action of the springs D to force the mastic out through the opening 5 as the body is moved over the surface 39.  The crown effect given to the mastic deposited on the surface 39 may be adjusted by means of a manually slidable wedge S mounted on a pressure-rod Q which has one end bearing on the centre portion of the flexible guide K.  A coil spring R is mounted on the rod Q with one end secured to the rod.  The wedge S varies the compression in the spring.  When the operator wants to apply mastic to a ceiling he swings the housing A into the desired angular position with respect to the handle F and then he moves a hand grip member J towards the handle and causes a projection 26 on a bell-crank lever H to enter any desired recess 24 in a quadrant G mounted on the plate B.  This will hold the handle in a rigid position with respect to the plate B and since this plate is held in normal position by the coil springs D, the housing A will be held in a fixed angular position with respect to the handle F.

The machine comprises a spring-pressed hammer 11, 12 for driving the staples 7 which rest on the base 2 of the machine. A pusher 5 and spring 6 press the operative staple strip towards a pivoted front shutter 9, and other strips of staples 7a are held above the strip 7 by a weight 14 with spring-pressed releaseable catches 16. A knob 21 and a lug 20 integral with or attached to the push-rod, 5 enable the push-rod to be pulled to the rear when desired. The lug 20 may be spring mounted so that is returns to its forward position after pulling the push rod to the rear. When the strip of staple 7 is exhausted, the push-rod 5 is withdrawn to the rear and a new strip of staples 7a then enters into the operative position under the action of the weight 14.
