[Class 38 (ii)] [Also in Group XI] The supply of high-frequency current to the heating coil of induction heating apparatus is effected through a transformer comprising a fixed primary winding 89 located within a recess in the inner face of a cylindrical core 305, and a movable secondary winding 94 located within a recess on the outer face of a cylindrical core 328, the secondary being connected to the heating coil 63 which is arranged to move with the secondary so as to enter the work 65 to he heated when the secondary moves into coupling relationship with the primary. The secondary core 328 may be provided with an Extension 310 which completes the magnetic circuit of the primary when the secondary moves to the inoperative position. Where power factor correction is effected by a condenser 72 connected across the primary terminals 90, 91, this extension may be tapered as shown so as to introduce a gradually widening air gap into the primary magnetic circuit. Where power factor correction is effected by a condenser connected across the secondary terminals, the core extension is of the same diameter throughout its length, Fig. 9 (not shown). The cores are built up from radially disposed laminations of tapered thickness and are clamped between end rings 313, 314, 325, 326, an intermediate ring being provided on the secondary structure in modifications in which the extension 310 is separate from the secondary core 328. The windings are formed from hollow conductors through which cooling liquid, which may also pass through the secondary connections to the heating coil 63, is circulated. In one form, Fig. 13 (not shown), the secondary core extension is omitted, and a switch in the primary circuit is arranged to be opened as the secondary moves into the inoperative position. The transformer is mounted by means of a ring bracket 83 on a column 20 on which the other components of the induction heating apparatus are mounted. These components and their association with the transformer are fully described in Specification 503,130, [Group XI], which is referred to. Additional Figures illustrating this subject-matter were included in the present Specification as open to inspection under Sect. 91, but do not appear in that Specification as accepted.

Patent GB-672418-A (GB)
Title: Improvements relating to the recovery of nickel and copper from ores
IPC: C22B5/02
Filed: 1950-04-14
Abstract: A process for recovering nickel and copper from sulphides containing them comprises flash smelting the sulphides in a furnace to yield a matte containing nickel and copper and an overlying slag, subsequently or simultaneously flash smelting finely divided iron sulphide, e.g. as pyrrhotite, with a flux to oxidize and slag part of the sulphide and convert the remainder into molten drops of iron sulphide, and allowing these drops to fall through the slag and carry nickel and copper contained in it into the matte.  The nickel and copper sulphides on the one hand and the pyrrhotite on the other hand may be separately produced in the form of concentrates from a pyrrhotitic ore.  When the iron sulphide used is in the form of pyrrhotite an oxygen-rich gas, e.g. containing 90-98 per cent of oxygen, is used in sufficient quantity to oxidize one-quarter to two-thirds of the iron sulphide in the pyrrhotite used may be 20-35 per cent by weight of the nickel and copper sulphides which are flash smelted.  The nickel and copper sulphides may be smelted by injection through one or more burners, the iron sulphide being subsequently injected through the same burners, or the two may be injected simultaneously through burners at opposite ends of the furnace. In the first case the first formed matte may be tapped before flash smelting the iron sulphide, the low-grade matte then formed being separately tapped.  In the second case the high and low grade mattes may be separated, e.g. by a barrier over which the slag may flow, to be tapped-off on the side of the barrier at which the low grade matte is formed.  Nickel and copper sulphides may be smelted in one furnace and iron sulphide in an adjacent furnace, the slag formed in the furnace flowing through a connection to the second furnace and being tapped therefrom. Alternatively, where one furnace is used the slag and matte may be tapped at opposite ends and thus flow in countercurrent with p  one another.  Any cobalt present is also concentrated in the matte.

Abstract: 1,041,733. Comparing colours. F. PIRINGER. March 8, 1963 [March 8, 1962], No. 9438/63. Heading G2J. In a method of comparing the colour of a sample, with standard colours, a series of inclined mirrors, 42, Fig. 6 (not shown), or a refracting body having various inclined surfaces such as 49, or 58, Figs.7, 12, (not shown), produce a number of identical images, e.g. 9, of the same small area of the sample, and each is compared with standard colours which differ only very slightly so that the eye can detect slight differences of the sample colour from a desired standard. For example, Fig. 1 (not shown), a square may divided into nine parts having an upper horizontal row A.C. varying from light orange-red to deep orange-red, a middle row d-f varying from light carmine-red to deep carminered and a lower row g-i varying from light purplered to deep purple-red the desired standard being e, carmine-red, and by comparison it can be determined whether the sample is more yellowish or more bluish by conidering vertical rows or more light or more dark by considering horizontal rows. In apparatus as in Fig. 11, a sample at 36 or 36<SP>1</SP> is seen in eyepiece Oc as nine different images either by reflection or refraction by member 42, depending on whether the member is a series of reflecting or refracting sections.
