Title: A method of producing incandescent lamp filaments
IPC: H01K3/02
Filed: 1961-08-10
Abstract: 927,007. Making incandescent lamp filaments. EGYESULT IZZOLAMPA ES VILLAMOSSAGI R.T. Aug. 10, 1961 [Aug. 12, 1960], No. 28964/61. Class 39 (2). [Also in Group XXII] In a method of producing helical filaments with a large number of turns per unit length and/or a high ratio of the diameter of the core on which the filament is wound to the diameter of the wire of the filament, another wire removable by chemical means is wound around the filament wire which is then formed into a helix by winding on a core and heat treated, the surrounding wire being them removed chemically and the core extracted. The winding core may be of tungsten and is of smaller diameter than the usual core by twice the diameter of the surrounding wire. The latter may be of molybdenum or iron and its diameter is half the clearance to be maintained between adjacent turns of the helix, being wound with adjacent turns substantially in contact. A helix of other than circular cross-section may be produced using a core of non-circular cross-section.

Title: Improvements in or relating to egg products and processes for producing same
IPC: A23B5/04
Filed: 1928-10-09
Abstract: 327,701. Epstein, A. K. Oct. 9, 1928. Preserving egg yolks.-Egg yolks are preserved by addition of a suitable substantially neutral edible salt and either, or both, a substantially neutral edible water-soluble organic hydroxyl compound containing at least one hydroxyl group and capable of lowering the freezing point of water, or an edible substance producing hydrogen ions when in contact with the egg material, so as materially to modify the physical characteristics of the egg material when thawed after being frozen, and freezing the mixture. The salt added is preferably sodium chloride. Di-sodium hydrogen phosphate treated with sufficient sodium di-hydrogen phosphate to give a substantially neutral phosphate mixture, or tri-sodium citrate to which sufficient citric acid is added to render it neutral, or tri-sodium phosphate admixed with sufficient phosphoric acid to make it substantially neutral may also be employed. The organic hydroxyl compounds used include glycerine, cane sugar, lactose, or their equivalents. Acetic, lactic, citric, tartaric, malic, succinic or phosphoric acid or concentrated or dried lemon juice may be used as the substance producing hydrogen ions. Sufficient acid may be added to retard putrefaction when the yolk is in the liquid state. In an example, 4.6 lbs. of salt, 4.6 lbs. of sugar and 0.5 per cent of acid are added to 90 1bs. of the yolk material which is then frozen until required for use. When thawed the material has the consistency desired. In another example, 5 pounds of cane sugar and 5 pounds of sodium chloride are mixed with about 90 lbs. of yolk and frozen. According to the use to which the final product is to be put other ingredients such as mustard oil or other condimental or flavouring substances may be added before freezing. In a further example, 8.4 lbs. of the salt, e.g. sodium chloride, and of a lb. of glacial acetic acid diluted with an equal amount of water, or of an equivalent acid, are mixed for a few minutes in a mixer with 91 lbs. of yolk material and then mixture poured into the cans and frozen. The acetic acid may be replaced by <2>/3 of a lb. of a 50 per cent aqueous solution of tartaric acid. If 4.5 lbs. of salt are used in the mixture a larger amount, about 0.8 lbs., of acid may be used. Generally 0.5 to 1.5 per cent of acid and 2 to 8 per cent of salt are used. The acids used mav be dissolved in water or other suitable solvent. The salts may be added dry or wetted with water or the acid solution. The thawed product has a smooth texture and the fluidity and mobility can be controlled by the additions employed to enable it to be readily incorporated and emulsified with oils and other materials. The effects obtained when only acid or hydroxyl compound is added to the yolk material before freezing are described. Reference is made to the Public Health (Preservatives &c., in Food) Regulations, 1925.

Title: Improvements in can body ending machines
IPC: B21D51/26
Filed: 1919-11-24
Abstract: 158,746. Fitzsimons, T. F. Nov. 24, 1919. Hollow-ware.-In a machine for securing the ends of cans to the bodies by crimping, flux is applied to the ends of the bodies while they are being intermittently fed by a belt to a position where two ends are automatically applied by anvils and crimped on by groups of inwardly moving vice jaws. The bodies 22, Fig. 1, are fed into a shoot 23 whence they are admitted singly, by a lever 123 operated by a cam 128, to a conveyer 25 which is intermittently advanced by a crank on the driving-shaft 36 operating a ratchet on the shaft 41. Each body passes spiriting pads 60, which are advanced to apply flux, and then comes between two headers, in which position it is centred by bars 69 operated by a cam 63. The body, in passing, engages a roller 81, thereby actuating mechanism 80, 79 78, 77 to withdraw pins 75, Figs. 1 and 5, and advance pins 74, thus allowing one end a to fall to the bottom of each shoot 73. The headers 84, Fig. 5, are then advanced by cams on the shaft 36, acting through adjustable pins 87, anvils 91 forcing the ends over the body, then jaws 93, Fig. 4, are moved by toggles 110 and a cam-oscillated plate 61 which has slots 114 to engage the knee joint pins 112. The headers 84 &c. are then withdrawn by springs 104, 131, the pins 94 being held by pawls 97 to strip and centre the work; these pawls are withdrawn when the header slides 83 engage setscrews 102. The ends are fed to the shoot 73 from a pack 71, Fig. 12, resting on forks 132 by means of slides 140 which are oscillated by an eccentric 50. Fig. 1, through mechanism 52, 55, 58. These slides have rollers 147 which, as they move down, press pads 144 to grip the lowest ends in the pack, then they engage and move down carriers 170 and fingers 150 which force the lowest end 131 from the pads and past spring pins 154. The forks 132 are withdrawn by their rollers 135 engaging fixed inclines 136 so that the end 131 falls on the incline 171, Fig. 5, and into the shoot 73. During the return movement of the slides 140 pins 157 engage and tilt the fingers 150 to allow the pack when released by the pads 144 to settle on the forks 132. Shoes 160 keep the fingers 150 in the retracted position, thus preventing the feed, if the roller 81, Fig. 1, to which they are connected by mechanism 162, 82, is not actuated by a body 22. In a modification, the plate 61, Fig. 4, has inclined slots engaged by pins fixed in the jaws 93 which are actuated thereby. The ends may be finally sweated or soldered.

Title: Sewing machine lubrication
IPC: D05B71/00
Filed: 1951-12-17
Abstract: 691,663. Sewing-machine lubrication. FAIRWEATHER, W. C. (Singer Manufacturing Co.). Dec. 17, 1951,No. 29428/51. Class 12 (iii). A sewing-machine comprises a hollow frame provided with a shaft-bearing and an oilcollecting recess at the outward side of the bearing, means within the frame for supplying lubricant to the bearing, an oil-return conduit leading from the recess and terminating within the frame, and a vapour-lock associated with the conduit to prevent lubricant-laden air within the frame from passing through the conduit. As shown, a shaft 6 is journalled in bearings including a bushing 5 in the upper arm of a chainstitch sewing-machine. The shaft carries a hand-wheel 8 and a gear 12 meshing with a gear 13 secured to a vertical shaft 14, which at its lower end is operatively connected to an oil pump 22. The pump supplies oil through a pipe 24 to a longitudinal bore 29 in the shaft 6. The oil passes through a radial bore 30 to the gearwheels 12, 13 and through a radial bore 31 to a helical groove 32 on the shaft and to a recess 34 in the bushing 5. An oil-sling 33 formed upon the hand-wheel 8 projects into the recess and flings the oil against the walls of the recess. The oil runs down an inclined conduit 35 which has an opening 37 in which is fitted a tube 41. The tube is carried by a sheet-metal strap 38 secured to the outer periphery of the bushing 5 by a screw 39 passing through an aperture 40 in the strap. The lower portion of the tube extends into a wall 42 which is always full of oil, providing a liquid seal which prevents oil-laden air from passing up through the conduit 35. In a modification the tube 41 and strap 38 are replaced by a smaller tube and a spring strap of arcuate shape larger than a semi-circle so that it is self-clamping on the bushing. The tube contains a wire-mesh screen, the holes in which are normally closed by droplets of oil, thereby forming the liquid seal preventing escape of oilladen air through the conduit 35.
