Title: Method of and apparatus for welding electrically thermoplastic sheet material
IPC: B29C65/00
Filed: 1950-05-26
Abstract: 679,283. Seaming thermoplastic sheets. COMMUNICATIONS PATENTS, Ltd. May 26, 1950 [May 27, 1949], No. 13333/50. Class 42 (i). [Also in Group XI] Thermoplastic strip or sheet material is welded by subjecting it to pressure and heat applied between metal ribbons 12, 17, both heated by passage of current for a short period determined by an adjustable timing means, the ribbons being allowed to cool before removal of the thermoplastic. The two metal strips 12, 17 have a thickness of 0.01-0.5 mm. and may be maintained at a temperature just below the softening temperature of the plastic, being heated to welding temperature for a period controlled by the discharge of one or more capacitors. The strips 12, 17 of nickel chromium iron alloy are mounted on bars 5, 6 from which they are insulated by layers of silicone rubber. A.C. is supplied from a transformer 33 to the ends of the strips which pass over rollers 18 on the bars 5, 6 to clamps 14 and may be held taut by springs. The bar 5 is fixed to a casing 4 containing the electric gear and the bar 6 is on arms 7 hinged to the rear of the casing 4. The bar 6 is moved down against a spring to the lower bar 5 by a solenoid 10 to clamp the plastic on operation of a foot- or hand-operated switch 30. D.C. is supplied at 24 and when the switch 30 is off, relays A-C are released and an indicator lamp 31 is lit. When switch 30 is operated, relay A lights indicator lamp 32 and operates through contacts Al, relay B, which energizes the solenoid 10 to operate the clamp. Relay B also actuates through contacts B<SP>1</SP>, relay C which energizes through contact C3 the transformer 33 to pass current through the heating strips 12, 17. Relay C through contacts Cl disconnects relay A from the D.C. supply, so that relay A is energized only by the capacitor 26, and when this is discharged relay A terminates the heating of the strips by operating contacts A4. Release of relay A leaves relay B operated by the charge of capacitor 27 and when this is discharged relay B is released and the solenoid 10 is de-energized, whereupon the bars 5, 6 open under action of the spring. Capacitors 26, 27 are associated with potentiometers 28, 29 to adjust the timing, the latter being adjusted by control knobs 22, 23. Other timing means, e.g. clockwork or electronic valves may be used. Personal operation may be replaced by automatic means for feeding the plastic to and from the apparatus. A small current may be passed constantly through the strips 12, 17 by by-passing contacts A4, C3 of the primary of the transformer 33.

IPC: C22C1/02
Abstract: 133,981. Blackwell, H. A. July 30, 1918. Alloys; thermo-aluminic and like mixtures and metal-extracting processes.-Ferro-tungsten is obtained by subjecting tungsten ore, such as wolframite, scheelite, hubnerite, &c., to a preliminary magnetic separation, followed by roasting or calcining, without any chemical or other metallurgical treatment or preparation, and subsequently mixing the same in fine granular or powdered form with aluminium or other analogous reducing-element in granular form in the requisite proportions, and setting the mixture into reaction. If the oie contains very little iron oxide and manganese oxide, a suitable proportion of these bodies is added. Unless the ore contains sufficient lime or analogous fluxing-material, fluor-spar or other flux is added. Alloys of copper, nickel, aluminium, &c. with iron and tungsten are obtained by mixing with the oxides or ores of the former metals roasted or calcined tungsten ore, previously purified as stated above, together with aluminium or analogous reducing- element, and setting the mixture into reaction.

Title: Improvements in and relating to gaseous electric discharge devices
IPC: H01J61/073
Filed: 1935-05-07
Abstract: 446,860. Thermionic cathodes. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. May 7, 1935, No. 13447. Convention date, May 8, 1934. [Class 39 (i)] A cathode for use in gaseous electric discharge devices, such as high pressure metal vapour lamps, comprises an elongated body of refractory metal having a curved configuration and contained within a loosely-mounted closely-wound helix of refractory wire, with the loose turns at the region of curvature containing the body eccentrically and bearing against the body at the inside of the curve, a thermionically active substance being disposed on the body and the helix, and in the interstices between them. In one form the cathode comprises a V-shaped portion 17, Fig. 3, projecting into the discharge space and surrounded by a single turn. The ends are connected together by a cross-bar 15 supported on the leading-in wire 13. In another form, for heavier currents, the refractory body is wound into a helix 22, Fig. 5, with its axis perpendicular to the lamp axis. The ends of the helix are brought out to separate leads 23. In each case the refractory body is surrounded by a closely-wound helix loosely mounted thereon, forming a store of electronemitting material, At the curved parts the helix bears on the inside of the curve, the turns on the outer side separating slightly and serving to facilitate starting where they project into the discharge space. A lamp is described for use with the cathodes, comprising a tubular envelope supported within an outer jacket by ring spacers at each end which are clamped together by two longitudinal braces one of which acts as the lead to the cathode at the far end. A starting electrode of metal gauze is wrapped about the envelope one-third of the length of the discharge from one electrode and is connected to the other electrode. The portion of the envelope near the ends of the tube may be of uranium borosilicate glass through which the electrodes leads are sealed, and which also absorbs infra-red radiation and maintains the ends of the tube at a higher temperature. The filling may be argon at 5 mms. pressure and mercury, sodium or cadmium in the unsaturated condition. The space between the inner and outer envelopes may contain nitrogen at a pressure of half an atmosphere. Specification 433,520 is referred to.

Abstract: 1,188,485. Orientating caps. ANCHOR HOCKING CORP. 14 March, 1969 [14 March, 1968], No. 13498/69. Heading B8S. Caps from a hopper are discharged down shoot 2 and orientated by engagement with horizontal star wheel 9, with vertical wheel 13, and with the guiding surfaces of the shoot. Thus, Fig. 5, the caps 3A which have their open face downwards on the bottom 7 of shoot 2 pass over the wheel 13 and under the wheel 9 without change of orientation. Caps 3B which have their hollow portions upwards are tilted as they pass over wheel 13, the tilting being assisted by the bars 11 carried by wheel 9 so that the caps assume the vertical position and are then guided by the shape of the shoot and by cover plate 17 to be displaced by 180 degrees into the reverse position. In this way all the caps discharged at the bottom of the shoot are uniformally orientated with their open end downwards.

Title: Improvements in bleaching process and composition
IPC: D06L4/23
Filed: 1944-07-18
Abstract: The cold bleaching of cellulose fibres (e.g. cotton or wood pulp) is effected by the action of a bleaching composition comprising a bleaching agent containing halogen in combination with an alkali or alkaline-earth metal (e.g. sodium or calcium hypochlorite), and an inorganic glycosate (preferably a b -glucosate) which is soluble in water but capable of precipitation by bivalent ions to form colloidal particles.  By "inorganic glucosate" is denoted a compound of the general formula <FORM:0591537/IV/1> (wherein X represents hydrogen or an alkali metal, Y an  alkali metal or the residue of a phosphorus oxyacid or an alkali metal salt thereof and R a carbohydrate radical) preferably prepared by condensing a b -glucoside with an inorganic salt or other compound of an alkali metal or phosphorus, e.g. sodium glucosates (X = Y = Na), phospho-glucosates (X = H, Y = PO3H2), sodium pyrophosphoglucosates (X = H, Y = P2O6Na3) and sodium tetraphosphoglucosates (X = H, Y = P4O12Na5).  The proportions of the glucosate may be from 1 to 100 (but usually not more than 25) parts by weight per million parts by weight of bleaching solution.  In examples, caustic boiled and washed cotton linters are treated with cold calcium hypochlorite solution in the presence of various quantities of sodium tetraphosphoglucosate (in which R is a glucose residue) and, for comparison, in the absence of the glucosate.
