Title: Method of manufacturing heating conductors for electric heating apparatus
IPC: C23C14/04
Filed: 1953-09-02
Abstract: 737,058. Coating with metals. WURTTEMBERGISCHE METALLWARENFABRIK. Sept. 2, 1953 [Sept. 2, 1952], No. 24314/53. Class 82 (2). [Also in Groups XI and XXIII] Electrically heated articles such as frying-pans or baking- or boiling-vessels have walls 1 of insulating material such as porcelain or of metal covered with enamel 2 on which are deposited metal strips 3 forming heating resistances by condensation of metal vapour or cathodic sputtering in vacuo. The insulating walls are heated and are covered by a stencil with openings giving the required pattern, e.g. a spiral or zigzag line to the deposit, which may be a noble metal, e.g. gold. Contact portions 4 of the strips 3 are thickened with metal by applying further metal through a second stencil, and by applying a metallic burning-in paste, or by insetting or fusing small metal plates into the insulating support, preferably before deposition of the metal strip which is of uniform thickness. The insulating surface may be roughened by etching or may carry an insulating layer improving adhesion of the metal strip. The metal strip 3 after deposition may be burnt into the insulating strip at a temperature above its normal working temperature. The strip 3 may be embedded or covered by a screening insulating or protecting layer 6, e.g. of enamel entirely covering the support and strip except at the contact surfaces 4. The enamel is one in which the alkali oxides have been replaced by oxides of lower ionic conductivity (see Group XXIII). A contact arm 5 is provided.

Filed: 1922-07-17
Abstract: 205,142. Darnell, C. H., Evans, E. W., and Evans, R. C. July 17, 1922. Ruling-machines.-In a machine for ruling paper on one or both sides both transversely and longitudinally at a single passage through the machine, the lines transverse to the direction of motion of the paper are produced by rules adjustably mounted on positively driven rollers. The paper is fed from a roll 32, Fig. 2, over guide rollers 33 to a drum 4. Continuous longitudinal lines are ruled as the web passes around this drum by ruling-discs 5 mounted on a spindle 6 and engaging with an inking-roller 12. The discs and inking-roller are carried by a frame 35 pivoted at 34 so as to be adjusted by a screwed rod 37 and nut 36. The transverse lines are ruled by a transverse ruler 24 carried by a frame 35<1> pivoted and adjusted similarly to the frame 35. The transverse ruler consists of a central core 25, Fig. 3, to which the rules 28 are secured by wedge-shaped pieces 26 screwed into it. When both sides of the paper are to be ruled, the web passes from the drum 4 over a blotting-roller 43 and guide rollers 44 to a similar arrangement to the above. On leaving the second ruling-drum, the paper passes over rollers 50, 51 to trimming-mechanism and feed rollers 52, and is cut into lengths by a rotary knife 54. The lengths of paper fall on to an endless belt 55 operated intermittently by a cam 58, levers 63, 66, 61 and ratchet and pawl mechanism 62. The machine is driven from a central shaft 45, gear wheels 46, 47 driving the drum 4, which rotates a pinion 23<1> on the spindle of the transverse ruler 24. The disc rulers and the inking rollers may be driven either frictionally or by gearing. Separate reservoirs may be provided for the disc rulers so that lines of different colours mav be ruled. A hand or treadle operated modification of the machine is described for ruling single sheets on one side only both transversely and longitudinally at a single passage through the machine, the ruling-devices being constructed and driven as described above, and being operated by cam surfaces on the drum 4 through bell-crank levers so as to be moved against the paper and drum as the sheet passes over the drum.
