Abstract: 1526746 Steel making KLOCKNER-WERKE AG 15 Oct 1975 [24 Oct 1974] 42175/75 Heading C7D [Also in Division F4] A steel making plant comprises a melting or pre-heating vessel (for scrap, sponge iron or pellets) and a refining vessel, wherein the refining vessel has a tilting axis such that the vessel may receive material from the melting or pre-heating vessel continuously, even when the refining vessel is tilted for tapping. The refining vessel may be an electric arc or induction furnace. In Fig. 1, melt from vessel 1 falls into the electric arc furnace 2, the horizontal tilting axis being shown at A. The inlet 10 is situated at one side of the furnace (Fig. 2, (not shown), and is such that melt does not contact the walls of the furnace 2 or the wall of the inlet during charging. In the case of an induction furnace, the inlet may be in the centre of the roof and may be elongated in the directions of tapping. The furnace 2 includes a gas-tight door 12 for additives (e.g. CaO) and gas evacuation duct 13, and may be fitted with lances or bottom blowing tuyeres for supplying O 2 .

Abstract: 438,740. Colour photography; reversal development. OPTICOLOR AKT.-GES., Glarus, Switzerland. July 13, 1934, No. 20633. Convention date, July 20, 1933. [Class 98 (ii)] In the production of lenticular or multicolour screen pictures by the method in which the original film exposed in the camera is developed as a negative, a print is taken from it and developed as a positive, and a print is taken from the positive and developed as a positive by the reversal process, a silver bromide solvent such as ammonia (about 2 per cent) is added to the first developer of the reversal process to increase its resolving power. The negative emulsion is highly sensitive and of coarse grain, and the positive emulsions are of fine grain. The first printing may be by optical projection, using an objective of aperture smaller than that of the lenticles in conjunction with fixed or movable plane mirrors as described in Specifications 421,084 and 422,983. In the case of films having cylindrical lenticles, at least one of the prints may be produced on a sensitive film whose lenticles are inclined in known manner at a large angle (30-90‹) to those of the film from which it is printed. Specification 10611/09, [Class 98 (ii)], also is referred to. The Specification as open to inspection under Sect. 91 states also that the various images may be reproduced in thin emulsion layers, preferably thinner than 0À008 mm. This subject-matter does not appear in the Specification as accepted.
