Abstract: 949,155. Capacitors. SIEMENS & HALSKE A.G. Nov. 6, 1962 [Nov. 7, 1961], No. 41885/62. Heading H1M. A roll capacitor is constructed by applying a coat of dielectric material solution to a carrier tape to solidify into a film strip, vaporizing a metal coating on one face of the strip, and winding two or more such strips in superposition ; at least two of such metallized strips being bonded together before winding, e.g. by cementing or heat bonding with removal of the carrier strips. The dielectric film may be of acetyl cellulose, the carrier tapes of paper impregnated with a high melting point carbohydrate, and the metallized layers coated with polystyrol varnish, after which four composite film strips are wound as a capacitor so that the acetylcellulose layers lie in the field free space while the polystyrol layers are electrically active; the strips being bonded in pairs by their acetylcellulose layers and the result ant two strips subsequently bonded similarly before winding. Alternatively, the film strips may be fabricated of a thin varnish layer applied to the carrier tape, a vaporized metal coating thereon, and an overlying thicker dielectric layer as set forth in Specification 926,070; two such composite strips being wound and bonded together. Rotary feed rollers 1, 2 carry rollers of thin acetylcellulose film strips 5, 6 superimposed on carrier tapes 3, 4 of paper impregnated with a high melting point carbohydrate. An aluminium layer is vaporized on the acetylcellulose layer and covered by a further such layer in varnish form. The tapes pass over preheating rollers 7, 8 at 100 C. where the carrier tapes are removed and rerolled for future use, after which the film strips pass in superimposition round a drum 9 at 140  C. and are there bonded together face to back into a composite strip which passes over cooling roller 10 to a receiving roller 11 driven by a slip clutch (not shown). By rearrangement of the rollers, the films may be bonded back to back or face to face, and the bonded films may then be rolled into a capacitor assembly in the normal manner. The oppose metal layers of the film strips may be electrically charged to opposite potentials during bonding. Rollers 1, 2, 11 are pivotable about centres 14.

Title: A process in the roasting of ore for removing quantities of tin contained therein
IPC: C22B5/16
Filed: 1969-08-22
Abstract: 1282625 Removing tin from ores as sulphide BOLIDEN AB 22 Aug 1969 [2 Sept 1968] 41925/69 Heading C1A The tin content of an ore (which bears iron sulphide or is mixed with iron sulphide in finely divided form) is volatilized in a furnace into which the ore is introduced and is suspended therein in a gas stream which consists of oxygen, the gas stream being introduced at such quantities and at such concentration that the partial pressure of oxygen in the resulting roaster gas is defined by a pair of curves (Fig. 1, not shown) relating partial pressure to temperature whereafter the roasted ore is separated from the roaster gas at such a temperature that the tin compounds exist in gas form. The partial pressure of oxygen may vary from 10<SP>-15</SP> to 10<SP>-5</SP> atms. at temperatures of 700-1100‹ C. Thus tin is separated as SnS, the FeS is converted to e.g. magnetite, and any elemental sulphur in the gas stream after separation of solid material therefrom (e.g. in a hot cyclone) may be oxidized to SO 2  which may be further converted to H 2 SO 4 . The SnS is removed from the roaster gas by e.g. cooling and washing with water in a washing tower. The furnace used may be a fluidizing furnace; and oxidic iron material may also be introduced to the furnace.

Filed: 1960-12-07
Abstract: 968,685. Facsimile transmission systems. ASAHI SHIMBUNSHA PUBLISHING CO. Ltd. Dec. 7, 1960 [Dec. 9, 1959], No. 42153/60. Drawings to Specification. Heading H4F. In facsimile transmission system for subjectmatter having light and dark portions (e.g. newspaper print and half-tone etched photographs &c.) the electrical signal produced by scanning such subject-matter is restricted in bandwidth by removing second and higher order harmonics so as to provide a signal having a fundamental frequency given by the imerse of the time taken to scan the minimum space between two neighbouring dark portions. The band-width restriction, which is produced by suitable filters may be effected directly on the signal from the (photo-electric) scanning means, the filtered signal then being employed to modulate a carrier wave for transmission over a line or the filtering may be effected on an already modulated carrier wave. At the receiving end the signal, after amplification, filtering and detection, is supplied to a " jumpup " circuit which supplies a rectangular wave output which has one value when the instantaneous value of the received signal goes below a selected value and has a different value when the instantaneous value of the received signal goes above the selected value. The rectangular wave is then employed in a recording system which may utilize a crater lamp or glow discharge tube. The invention is particularly concerned with the transmission of Chinese characters in Ming style.
