Title: Improvements in writing instruments
Inventor: SHAW JACK HILLEL
IPC: B43K24/08
Filed: 1959-02-17
Abstract: 886,414. Writing instruments. SHAW REGENT Ltd. May 16, 1960 [Feb. 17, 1959], No. 5502/59. Class 146(3) In a retractable writing instrument, e.g. a ball-point pen, comprising a rearwardly biased writing unit 12, a plunger 19 depressible to project the writing unit, and a latch member 23 cooperating with a fixed stop 29 in the barrel to lock the unit in projected position, the latch member 23 has an abutment part 24 which is positioned between a downwards directed abutment on the plunger 19 and an upwards directed abutment on the writing unit 12 or the biasing means therefor and which bears slidably against the side of the barrel remote from the stop, the abutments on the plunger and on the writing unit being capable of exerting on the abutment part 24 a couple which tends to rotate the latch member in the direction required to engage it with the stop. The plunger has a forked portion at its inner end between the arms 21 of which the member 23 is positioned. The abutment part 24 of the member 23 is disc-shaped and in the projected position shown the flat forward face thereof lies in contact with the flattened rear surface of a pin 17 mounted on the rear end of the writing unit 17. The rear end 27 of the latch member projects through a hole in the side of the barrel the rear edge of which constitutes the stop 29. When the end 27 is pressed into the barrel the writing unit is retracted by a spring 16, the end 27 being then housed almost completely in the space between the arms 21 so that the part 24 engages the pin 17 only with its lower left-hand portion as seen in Fig. 1. When the plunger 19 is depressed to project the unit the front ends of the arms 21 engage bevelled portions 25 on the part 24 and this, together with the rearward thrust exerted on the part 24 by the spring 16 through the pin 17, tends to rock the latch member clockwise so that when the end portion 27 thereof registers with the hole in the barrel it will move radially outwards into it and thereby lock the unit 12 in writing position.,

Patent GB-374008-A (GB)
Title: Improvements in slag treatment and apparatus therefor
IPC: C04B5/06
Filed: 1931-02-23
Abstract: 374,008. Mixing-apparatus. DUNN, E. P., Ferny Creek, Victoria, Australia. Feb. 23, 1931, No. 5657. Convention date, March 8, 1930. [Class 86.] A process for treating molten slag to produce constructional material, aggregates, artificial stone, &c. of uniform composition, consists in removing impurities from the slag by settling and also by oxidation, adding substances, e.g. silica, to combine chemically with the slag, and mechanically incorporating solid materials. The preliminary step of agitating the slag to homogenize it, is preferably included. Apparatus shown in Fig. 1 includes a settling device and mixer 2, a desulphurizing furnace 8 and a rotary furnace 13. The slag flows into the mixer 2 down a shoot 1 and therein passes under a baffle 5 to the outlet 6. Solid particles settle and are removed from an outlet 4. In the desulphurizing furnace, the slag flows in a thin stream over a series of inclined beds 9 where it is exposed to oxidizing gases from a firebox 11. The beds 9 are formed with projecting ridges or teeth to break up the stream. The slag then passes to a rotary furnace 13 in which material such as sand is chemically oombined with or dissolved in the slag. The sand is preheated in a rotary drum 16, heated by the waste gases from the furnace, and from the drum passes to a hopper 18 and is charged into the furnace by a screw conveyer 19. The furnace is formed with internal ribs 13c adapted to lift and drop the material. When the material to be combined is in lump form, a furnace shown in Fig. 8 is used instead of the rotary furnace. The lump material is placed in a series of compartments 33 through which the slag flows in succession. Solid materials may be incorporated with the molten slag in a rotary vertical cylinder 21, Fig. 4, having transverse bars 22 which may be hollow and cooled from within. The slag and added material are fed into the top of the cylinder and the mixed composition falls into moulds 25. Alternative mixing devices are (a) Fig. 7. a narrow trough 29 containing a series of star wheels 30 which may be hollow and cooled ; (b) Fig. 6, a fixed cylinder 26 containing a revolving mixing screw 28 and (c) a modification of the device shown in Fig. 6 having the screw fixed and the cylinder revolving.

Title: Improvements in and relating to methods of activating cathodes for electric discharge devices
IPC: H01J9/04
Filed: 1942-04-29
Abstract: 554,958. Cathode materials. BRITISH THOMSON-HOUSTON CO., Ltd. April 29, 1942, No. 5778. Convention date, April 30, 1941. [Class 39 (i)] A cathode of tungsten, nickel, molybdenum, tantalum or other oxidizable foundation metal is coated by dipping it in a fused mass of practically anhydrous barium strontium or calciumhydroxide and the hydroxide is then converted into oxide by heating it in a non-oxidizing atmosphere such as hydrogen. In a modification the hydroxide may be fused in situ on the cathode, as by heating a surface capable of holding a pellet, or by sprinkling powder on a heated cathode. Oxidation of the foundation meal is avoided. The temperature of the fusion should be low, 475-500 C., to avoid oxidation. The coating may be carried out in air or, preferably, in hydrogen or nitrogen. The conversion to oxide is carried out preferably before mounting in the discharge device, by heating in a current of hydrogen at atmosphere pressure, or argon or helium, for 1 minute at 650-800 C., and then preferably for 15 seconds at 900-1100 C. The resulting cathode is stable in air and needs little or no further activation after mounting ; if a long time intervenes before mounting it may be lacquered or kept in a vacuum or protective atmosphere. The cathode may be cold or thermionic, and is useful in either gas or vacuum tubes, such as television tubes, rectifiers, amplifiers and vapour or fluorescent lamps.

Abstract: In the emulsion polymerization of a mixture of 40 to 100 per cent of a diolefin and 0 to 60 per cent of a mono-olefinic monomer, the monomers are dispersed in water with a catalyst and 0.1 to 1.5 per cent of a "soap," the dispersion is heated with agitation until a latex containing more than 5 per cent solids is obtained, more soap is added in one or more increments or continuously and polymerization continued to produce a concentrated latex of large particle size. The "soaps" are emulsion stabilizers having a hydrophilic alkali metal or ammonium radical and a hydrophilic organic radical.  They may be formed in situ.  Specified are salts of rosin acids, e.g. pimeric, sapinic, colophonic, abietic and abietinic acids such as sodium abietate and potassium rosinate; of fatty acids, e.g. stearic, beheric, margaric, arachidic, palmitic, myristic, oleic and lauric acids such as sodium, potassium and ammonium oleates; of sulphonic acids, e.g. sodium naphthalene sulphonate; sulphates, e.g. sodium lauryl sulphate; sulphonated ethers R-O-RySO2-OX, esters R-COORySO2-OX, and amides RC-NH-RySO2-OX, where R and Ry are aliphatic monovalent and divalent hydrocarbon radicals respectively and X is alkali metal or ammonium.  Also included are neutralized alkylamines, e.g. dodecylamine hydrochloride and substituted alkylamine esters of fatty acids such as diethyl-ethanolamine oleate. Diolefins specified are butadiene-1,3, isoprene and other alkyl-substituted butadienes and the co-monomers may be styrene, acrylonitrile, methacrylonitrile, methyl acrylate, methacrylate and a -chloracrylate, 2,3-dichloro-styrene and vinyl pyridine. Suitable catalysts are potassium persulphate and potassium ferricyanide.  The emulsions may contain also n-or tert.-dodecyl mercaptan, trisodium phosphate, and inert hydrocarbons, and the sodium salts of polymerized alkyl naphthalene sulphonic acids. In an example: (2) a butadiene emulsion is heated at 125 DEG  F. for 12.5 hours to obtain 20 per cent solids content, when an aqueous solution of sodium hydroxide and a solution of stearic acid in warm styrene are added. After 43.5 hours an aqueous solution of potassium oleate is added and polymerization continued to 59 per cent solids content.
