Abstract: 1,262,391. Latching and unlatching switches. TELEMECCANICA ELETTRICA OFFICINE MECCANICHE RIUNITE S.p.A. 22 May, 1969 [14 June, 1968], No. 26058/69. Heading H1N. An electric switch push-button is latched in against the action of a retractive spring automatically at the end of the inward non-rotary movement and is unlatched by partial rotation of the push-button against the action of a spring tending to restore the push-button to its original angular position. As shown, pushbutton 5 is joined to slider 2 by screw 6 and has two recesses 10, which, when push-button 5 is pushed in against the action of retractive spring 4, are engaged automatically by the two arms of a U-shaped spring 11 held in place by hexagonal plate 13 which is force-fitted into the bore of housing 1. The bottoms of the recesses 10 are curved so that when push-button 5, knurled at 7, is partially rotated the curved bottoms of recesses 10 cam the arms of spring 11 open to release slider 2. Spring 4 is fast with slider 2 at one end and fast with housing 1 at the other end so that when push-button 5 is rotated to release the latch, spring 4 is twisted to return pushbutton 5 to its original angular position upon release. Slider 2 has projections 8 which slide in channels in housing 1 to limit angular movement. The end of slider 2 has two recesses 20 which are engaged by split plate 14 to retain slider 2 in housing 1 and to operate the contacts (not shown or described).

Drawings to Specification. Classes 100 (ii) and 100 (iv). [Also in Groups VIII and XV] Marks of different colours are produced on sheets of paper and like receiving surfaces by means of a marking liquid comprising an ink and a colour reactant substance, the sheet being in parts unsensitised and in part sensitised with a substance which reacts with the colour-reactant in the ink to produce a colour different from the ink, the marks on the unsensitised portions having thus the normal colour of the marking liquid while the marks on the sensitised portions have a colour which is a blend of the colour of the ink and that due to the colour reactions. Marking compositions specified are 3 per cent crystal violet lactone, 3 per cent Red dye Sudan III and 94 per cent chlorinated diphenyl having a 48 per cent chlorine content. The violet lactone may be replaced by malachite green lactone, Michler's Hydrol or its methyl ether or 3.3-bis(p-alkylaminophenyl) phthalides in which the alkyl group is methyl, ethyl or dipropyl. The sensitising material which is reactant with the above may be attapulgite, halloysite, magnesium trisilicate, kaolin, bentonite, zinc sulphide, calcium fluoride and zeolites in which the base exchange cations are replaced by cations of metals. In another example the fluid comprises 3 per cent of the acetate of rhodium B base, 3-8 per cent ferric ammonium sulphate and 94-89 per cent glycerine or hydrogenated methyl abietate and the surface is sensitised with tannic acid. The printing fluid may be applied from a type member having microscopic interconnecting pores or channels e.g. as described in Specifications 531,548, 550,023, 606,169, [Group IV (a)], and 608,998, by a ribbon impregnated with the fluid, or may be contained in droplets in a coating applied to a sheet placed adjacent to the underlying sheet coated with the co-reactant substance.

IPC: B23K13/02
Filed: 1924-11-08
Abstract: 234,373. Schr÷der, E. Nov. 8, 1924. Welding; brazing.-In a process of electric welding or brazing in which currents are induced in the zone of the seam by passing the parts through an alternating magnetic field, high-frequency current is used in conjunction with a field of restricted crosssectional area so that the points of crossing of the circle of induced current lie near one another in the immediate neighbourhood of the seam and thus conjoin their heating zones. Plates P, P<1> are held in contact by holders H, H<1> between the poles F of a magnetic field. The surface area of the poles is limited, being one square centimetre for plates one to two millimetres in thickness. With a field intensity of 7000-8000 lines per square centimetre, a high-frequency field current having a frequency of about 5000-7000 is used. The flow of induced current'in the work thus passes through the welding zone twice. By moving the plates between the poles the zone may first be given a preliminary heating and then a subsequent heating to welding temperature. The poles of the magnetic field may be arranged as shown in Fig. 3, the field being closed by a holder K. In welding tubes, the weld may be completed and the tubes fed by rollers. Currents of frequency up to 10,000 or 12,000 may be used. In brazing, the brazing material is put on the seam in the form of wire, tape or powder.
