Title: Improvements in and relating to the siliconizing of alloys containing iron
IPC: C23C10/16
Filed: 1952-07-11
Abstract: Silicon-containing protective layers are formed on alloys containing Fe and at least 3 per cent Mo or W or both, by treatment with a volatile silicon-halogen compound in a non-oxidising atmosphere at a temperature above 1000 DEG C. and below the melting point of the alloy.  The Mo or W may be present only in a thin surface layer produced e.g. by spraying, cladding, electrolysis, diffusion, vapour deposition or in a fused bath as described in Specification 635,595. Siliconizing gas may be formed by passing argon, helium, hydrogen, nitrogen, cracked ammonia or mixtures thereof freed from oxygen and water vapour, through liquid Si Cl4 at 0-30 DEG C. or by passing HCl vapour over ferro-silicon.  Such gas may be passed over a large surface area of metallic silicon or silicides at a temperature higher than the siliconizing temperature to convert part of the Si Cl4 vapour into sub-chlorides.  The treatment may be applied to steels the free carbon content of which does not exceed 0-4 per cent, the remaining carbon being bound by Ti, Nb, Ta, V, Zr, Cr, Mn or to alloys of iron with Cr, Ni, Co, Zr, Mn, Ti, Nb, Ta, V, even when the iron content is less than that of e.g. Ni or Co.  Examples refer to the treatment of an Fe-Mo alloy containing 7 per cent Mo; of a steel molybdenised in a fused bath of Na2 MoO4; of a steel coated by spraying with an Fe-W alloy containing 8 per cent W; and of a steel coated with Mo by treatment with H Cl gas passed over Mo powder.

Filed: 1916-12-07
Abstract: 111,361. Bill, R. W. Dec. 7, 1916. Quick-break switches; interlocking with lids.- Relates to quick-break electric switches of the iron-clad type and consists in so mounting the operating crank h, which extends wholly or halfway across the casing, in its bearing or bearings in the sides of the casing that the crank and its attached external handle n can be dropped into place entire when the lid b of the box is open; and in the provision of a self-adjusting universal connexion between the operating crank and the common actuating-bar f. In the construction shown in Fig. 1, the bearings for the crank are formed partly in the box a and partly in the lid at the division between them. When in place, the crank is secured at one end by an apertured plate m which encircles the trunnion h<1> and is secured to the box. The actuating-bar f, which is pivoted on the same pivots as the contact members d, has fixed upon it a U-shaped bracket i which receives the operating-crank h as a loose fit within it. The crank is retained within the bracket by means of a split pin passing through the upper ends of the bracket and the crank may be enlarged at k and slotted at l to allow of the passage of the split pins. The quick action is produced by spiral springs arranged round the switch pivots and having one end fixed and the other end engaged by the situating-bar so as, in the off movement, to be strained by the actuating- bar until the bar positively engages the contact members when a quick break results. A projection p engages the handle and prevents the switch being closed when the lid is open; the projection p is engaged by a hook part o on the handle when the lid is closed and the switch also closed so as to prevent the lid being opened.

Abstract: 1,188,776. Gas chromatography. SIEMENS A.G. 11 April, 1968 [14 April, 1967], No. 17713/68. Heading B1L. Gas chromatography column TS comprises two sections; the first (in the direction of flow) being surrounded by helical tube H, and the second being surrounded by concentric thermally conductive tubes Z and W and insulated with material I. The first section may be heated by means of heater B or cooled by coolant K which flows through helical tube H. The second section is heated in such a way as to produce a temperature gradient which decreases in the direction of flow; this may be produced by means of heater HK and cooling body KK, or alternatively by non-uniform electrical heater windings or by surrounding tube TS with a frusto-conical heater body whose apex points against the direction of flow. When coolant flows through tube H, the first section acts as a closed thermal gate to volatile material entrained in the carrier gas stream and none passes to the second section. When the first section is heated by heater B, the volatiles which have collected in the first section are evaporated and pass to the second section, whence they are separated by differential adsorption under the temperature gradient and emerge for detection as distinct bands.
