As shown in Fig. 1 an entrance mirror having a conical reflecting surface is disposed symmetrically on the lens axis. The axial rays deflected by the surface then fall on the convex reflecting surface of a secondary mirror 122 and are reflected therefrom toward points on a focal circle f p , f' p . The lens arrangement shown is well adapted to use in the "monopulse" system. That is, if sensors 126 for the energy being received are placed at 90 degree intervals along the focal circle fp, f' p , it is evident that appropriate sum and difference signals may be derived to determine whether or not the source (not shown) of the incident energy lies on the lens axis, and, if such source is not on the lens axis, the direction of such source relative to the sensors 126. The embodiment of Fig. 2 (not shown), shows the meridional section of a lens arrangement adapted to focus an initially divergent beam of wave propagated energy into a line.

[Class 51 (ii)] [Also in Group II] A constituent metal such as aluminium, is extracted from an alloy such as one with iron or silicon by means of a solvent metal such as zinc, zinc alloy, or mercury, in a furnace comprising means for passing the solvent metal in molten or vapour form through the alloy, collecting the resulting alloy ' in a chamber beneath the furnace, and separating the extracted metal from the solvent metal. The plant shown comprises a furnace structure wherein the alloy to be treated is moved in a series of containers 1 between an inlet 2 and outlet 3 and is subjected to the solvent action of molten zinc supplied through a passage 19, the resulting aluminium-zinc alloy being collected in a chamber 11 having outlets 4, 5 for floating and sunk impurities. The molten alloy is led by a passage 7 to a still 9 wherein the aluminium and zinc are separated, the aluminium being collected in a chamber III and the zinc passing to a chamber 14 from which it is supplied to the containers 1. Heating of the various chambers is effected by flues 32 through which gas admitted at 30 and burnt by air from flues 36 is passed. In modifications each container 1 before being finally discharged may be subjected to the action of zinc vapour in a chamber interposed in the vapour passage 13 between the still 9 and the chamber 14 ; or the whole of the extractions may be effected by zinc vapour, in which case the chamber 14 is dispensed with, and the vapour is led upwards through an extraction chamber to which the material to be treated is fed in successive small charges. Specification 537,400, [Group II], is referred to.

Abstract: 1338579 Electro-phoresis F R ELEVITCH 16 Nov 1970 [17 Nov 1969] 54511/70 Heading C7B [Also in Divisions B1 and B5] In preparation for the electro-phoresis of a specimen (e.g. of proteins or blood serum) in a gel, the gel is shaped and stored ready for use in apparatus comprising an impermeable base member 11 (which may be in the form of a multiplicity of segments or a continuous strip) and a cover member 10. The gel, which is in the form of a layer of aqueous permeable gel optionally containing reagent, is located between the members and is adherent to the base member, the inner surface of the cover member being uniformly coated with a normally solid thermoplastic essentially hydrocarbon material which is in surface contact with the gel and non-adherent to it. Thereby, the gel can be stored and the cover be easily separated there from when ready to perform the electro-phoresis. The layer of gel may be not more than 1 mm thick and this permits rapid migration under an applied voltage of 10 to 15 volts per cm. In the embodiment shown, the inner surface of cover member 10 has ribs 19 and projections 24a, 24b; in assembling the apparatus the edges of cover 10 are heat or adhesive-sealed to base member 11, gel is poured in through a vent 26 and the vent is capped or sealed. If the base member is a continuous strip it may then be cut into segments. For use, the cover member is stripped off and sample introduced into the wells formed in the gel by ribs 19 and projections 24. The base and/or cover member may be of polystyrene, polyethylene or polypropylene. The inner surface of the cover member may be pre-coated with a paraffin wax solution. The gel formulation may be 10% sucrose, 1 to 1.2% agarose in an aqueous solution of sodium barbital /HCL pH 8.6, optionally containing 0.50% to 0.2% polyvinyl alcohol. Other gels comprise starch, agar or acrylamide. In another embodiment Fig.10 (not shown) a package 110 comprises a plurality of base members each carrying a layer of gel without wells formed in it, one face of each base member being non-adherent to the adjacent gel layer and so forming the cover member for that gel layer.
