Title: Improvements in or relating to electric furnaces
IPC: H05B3/64
Filed: 1921-07-29
Abstract: 167,190. Lemoine, H. G. July 29, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Resistance furnaces.-A heating resistance for use with electric furnaces comprises a filament, strip, or helix of tungsten, chrome-nickel, carbon, or other material with a high melting-point embedded in a mass of refractory material such as magnesia, zinconia, or a mixture of these oxides. In the form shown, a strip of tungsten a, bent upon itself as shown and reinforced at the bends. is embedded in a mass b of zirconium oxide and magnesia, the circuit being completed through carbon rods c passing through the walls d of the furnace. The heating-element is manufactured by placing the tungsten strip or helix in a mould, pouring in the refractory material, and compressing the whole while an electric current is passed through the resistance. When the element cools, the strip or helix contracts, leaving a vacuum between itself and the refractory material. At high temperatures the refractory mass becomes conducting and serves as the heating resistance. The element may be made in cylindrical or conical form, and thorium, yttrium, or other similar oxides may be used instead of zirconium oxide.

IPC: C03C27/02
Filed: 1930-07-07
Abstract: Leads to be sealed vacuum tight into glass are made of alloys of iron with nickel, cobalt and manganese, such alloys being particularly suitable for sealing into borosilicate glasses.  For such glasses alloys of from 28-34 per cent nickel, 5-20 per cent cobalt and 0-1 per cent manganese, the remainder being iron, are employed.  Specific examples of alloys for sealing into particular glasses are given. For borosilicate glasses with expansivities between 3,0 and 5,5 x 106 cm. per cm. per degree alloys containing 23-28 per cent of nickel, 17-23 per cent of cobalt, 0-0,5 per cent of manganese, and 0-0,3 per cent of carbon are employed.  Generally the percentages should be connected by the relationship % nickel + 2,5 (% manganese) + 18 (% carbon)/% iron = 0,50-0,60.  For lead glass, alloys containing 23-45 per cent of nickel, 5-23 per cent of cobalt, and 0-1 per cent of manganese may be employed.  To improve the adhesion of the metal to the glass the alloy may be annealed in vacuo or in a bath of fused sodium nitrate or other salt which readily dissolves the metallic oxides.  Excess of carbon may be removed from the alloy by heating in hydrogen or in a fused salt bath containing 15 per cent sodium chloride and 85 per cent barium chloride.

Abstract: 1338679 Vegetable extracts; coffee; tea L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 19 April 1971 [19 Feb 1970] 20843/71 Heading A2B In the preparation of extracts from vegetable products in particular coffee or tea, with recovery of aromatic constituents, the collection of the aromatic constituents is effected by a gaseous sweep current at the location of escape in the gaseous state of said constituents, the sweep current being formed of a mixture of an inert gas, for example nitrogen or helium, that is difficult to condense, and a substantial proportion of a gas, for example carbon dioxide, its hydrate, argon, or water vapour, of a gas that is more easily condensable, and trapping the aromatic vapours on a snow-like structure formed in a condensing chamber by said more easily condensable gas. The aromas may be recovered either by subliming the snow and carrying the gas over the vegetable extract, or by mixing the snow and the extract and then subliming. The figure shows a suitable apparatus, coffee being ground in sealed mill 1 and extracted with water in 2, the extract being dehydrated to powder in 3, carbon dioxide and nitrogen being introduced to the mill via line 12, and the aromatised gases leaving via line 13, passing to two consecutive condensors 19 and 22, the latter being at lower temperature, and the carbon dioxide condenses carrying with it the aromatics. The snow from 22 may be sublimed and passes to chamber 23 which contains the coffee extract powder. The condensers may contain gas permeable packing or may preferably be empty.

Abstract: 605,883. Locking vehicle wheels. NEWTON, LANSDOWNE, & CO., Ltd., and KELLY, E. O. J. Aug. 20, 1945, No. 21229. [Class 79 (iii)] [Also in Group XXV] A lock for bicycles, having a sliding bolt locking a wheel, comprises a two-part casing, one part 1b, Fig. 1, of which is secured to the frame by a clip 37 with means, e.g. screws 38, manipulable only from within the part, a locking bolt 2 sliding through the casing, a removable plunger 4 passing through both parts of the casing to hold the parts together, a finger member 31, Fig. 2, within the casing for locking the bolt in shot position and at the same time engaging the finger 4 to prevent its removal, and locking mechanism within the casing operable by a key 3 to withdraw the finger from engagement with the bolt and the plunger to permit movement of the bolt to withdrawn position and removal of the plunger when desired to separate the parts of the casing. The locking mechanism, contained in the part 1 of the casing, consists of a set of two-part spring-loaded pin tumblers 5, Fig. 5, sliding in channels in plates 8, 9. The plate 8 lies in the bottom of the casing 1, while the L-shaped plate 9 lies above it, the channels for the tumblers being formed by upstanding flanges 12, 13. A spring 17 normally holds the plate 9 in the locked position, but when the key is inserted the tumblers are set to release the plate 9 as the end of the key abuts against a lug 20 on the plate which can then be moved against the spring action by further movement of the key. Above the locking mechanism are two co-planar plates 23, 24, Figs. 2 and 6, the latter being slidable to the extent of the clearance between a projecting part 23a on plate 23 and a cut-away part 24a in the plate 24. The plate 24 is moved by an upstanding lug 19 on the plate 9. Pivoted to the plate 23 at 28 is a lever plate 30, and an upstanding lug 26 on the plate 24 engages in a recess 32 in the pivoted plate 30. Movement of the plate 9 by the key thus rocks the plate 30, and an upstanding finger 31 thereon is withdrawn from a recess in the bolt 2 located above the plate 30, allowing the bolt to be retracted by the action of a spring 29. The finger 31 is also at the same time withdrawn from a recess 4a, Fig. 9, in the plunger 4 which passes through aligned slots in the two parts of the casing, thus allowing the plunger to be removed to open the casing if required. The plunger 4 is also secured by a screw passing through the part 1a of the casing from outside into a hole 4b in the plunger.
