[Class 125 (ii)] [Also in Group XXIII] Bottles and other receptacles are washed and filled by being caused to pass through a number of baths, under the action of gravity, in a direction transverse to their axes, and in direct contact with supporting surfaces which are arranged to present longitudinal and transverse slopes, the latter of which cause the receptacles to be inclined transversely in certain parts of their path for emptying and filling operations. The receptacles are fed along an inclined plane 21, Fig. 3, into a washing bath 11 in which they travel successively along a guideway 22, an inclined ramp 24, and a guideway 23; guides positioned above these supports serve to immerse the receptacles in the liquid in the bath. From this bath, the receptacles pass on to a transversely-inclined guideway 30 in a draining and emptying vessel 12, guides 31, 31<SP>1</SP> being provided for the receptacles. The receptacles are then fed down an inclined plane 34 and along a perforated guideway 35 in a rinsing or neutralising bath 13. The filling bath to which the receptacles then pass comprises, as shown in Fig. 5, an inclined plane 38 leading to a surface 39 and followed by a transversely-inclined surface 41 situated at a lower level; upper and lower guides 40, 42, are also provided in this bath. The receptacles are then passed to rinsing, corking, labelling and capsuling stations. If desired, power means may be provided, in addition to the gravity feed; for example, conveyers may be used for transferring the receptacles from the bath 12 to the bath 13 and from the bath 13 to the bath 14 in order to avoid the necessity of lifting them manually. Currents of liquid may be created in the baths in order to accelerate or retard the passage of the receptacles.

A surface of a metallic workpiece is locally heated in a chosen pattern, especially so as to cause diffusion into the surface of a desired treating material, by directing an electrolyte upwardly at said surface as a jet from a nozzle electrode, the nozzle having a configuration related to the pattern of heating desired, and passing current between the electrode and the workpiece to generate heat at the workpiece face, the electrolyte cascading downwardly from said face so that it cannot form a pool on the surface. The nozzle and workpiece may be vibrated relatively to one another, the jet of electrolyte may be pulsed e.g. up to 100 pulses/ second, and the heating current may be a combination of D. C. and A.C. up to 50 mc/s. The nozzle may be a tube of circular or triangular cross-section, or may be of trilobal form with a circular bore or of triangular form with three triangular bores within it. By varying the operating conditions the heated areas may be of the same form as the electrodes or may cover larger or smaller areas within the electrode peripheries. In a modification in which the workpiece has an internal bore heating of this internal surface is achieved as by pumping electrolyte through it while the workpiece is held between two apertured insulating plates supporting tubular electrodes through which the electrolyte is passed.

Title: Process for the preparation of metal alloys particularly for titanium, chromium, tungsten and like alloys
IPC: C22B5/04
Filed: 1932-04-28
Abstract: Alloys of titanium, tungsten, chromium, &c. are made by the exothermic reduction of their oxides by a melted mass containing iron, carbon, aluminium, silicon, calcium, magnesium, or their compounds, or mixtures of these reducing substances, in such a manner that with appropriate fluxes a fluid slag is produced at a low temperature.  The mass may be deprived of the superposed slag and put into reaction with a new oxidizing mixture to enrich the mass with the desired metals.  For making non-oxidizing alloys the process may comprise the two stages of exothermic reduction of oxide containing material to produce a ferro-chrome high in chromium, and the incorporation of the ferrochrome with molten iron under a protective slag.  This two-stage process forms the subject of Specification 402,430.
