Title: Process of smelting sulphidic copper or lead concentrates
IPC: C22B15/00
Filed: 1951-05-08
Abstract: Sulphidic copper or lead concentrates are granulated before being smelted and smelting is carried out in a rotary reverberatory furnace the diameter of which is equal to or greater than its length.  The concentrate may be raw or partially desulphurized and may be roasted before granulating in a sintering apparatus.  The sulphur content may be adjusted by addition of lime and/or alkaline earth metal oxides or hydroxides, in amounts of 1-10 per cent. by weight of the concentrates, in the sintering apparatus.  Granulation may be carried out in mixing drums, worm conveyers or eccentrically rotating closed vessels.  Carbon or sulphidic substance may be added to promote volatilization of constituents such as zinc or antimony.  The charge, containing concentrates and flux in correct proportions for matte and slag formation, is charged preheated to the furnace while firing is stopped or greatly reduced, the furnace having previously been partially emptied.  The furnace may be rotated slowly during charging to facilitate mixing of the materials.

Abstract: 723,919. Combined transmitting and receiving systems; duplex signalling. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 20, 1953 [May 1, 1952], No. 10955/52. Class 40 (5). In a two-way simultaneous communication system employing a plurality of combined transmitters and superheterodyne receivers having a common aerial 3, a stub coaxial line 8 shortcircuited at its end leads off the feeder between the aerial and receiver 2 and is of electrical length 2n, (2n+1) and (2n+2) quarter wavelengths at frequencies fc, fs and ft respectively, where fs is the received frequency selected, ft the transmitted frequency and fc the image frequency (Fig. 2) of ft with respect to fs, and the stub is arranged at a quarter wavelength of the frequency ft from the aerial feeder. Moreover the receiver local oscillator frequency fl is arranged to be mid-way between the frequencies fc and fs. In this way the receiver rejects not only the transmitted frequency ft but also the second channel frequency fc forming with fl the intermediate frequency fi. A stub 7 tuned to frequency fs is also arranged between the transmitter and aerial at a quarter wavelength of the received frequency fs from the aerial so that the received frequency fs is rejected from the transmitter feeder 5. A plurality of pairs of the transmitter-receivers may be employed with the transmitting and receiving frequencies ft, fs different for each pair but such that 1(ft-fs)1=2fi is constant for the system and each frequency interval 2fi is subdivided into and occupied by an integral number of carrier frequencies employed by other stations. The same subdivision is employed even if the bandwidth allotted to the stations of intervening frequency are alternately broad and narrow. The stub filter 8 may be a plurality of stubs tunable by pistons to the frequency ft and having a common spacing “#x from each other and the aerial, the same for all stations of a group, where #x is the wavelength corresponding to the mid-frequency of the whole group.
