Title: Scrap metal recovery and classification
IPC: C22B21/00
Filed: 1973-04-27
Abstract: 1382561 Sieving apparatus; impact pulverizers; comminuting at low temperatures LINDEMANN MASCHINENFABRIK GmbH 27 April 1973 [27 May 1972] 20196/73 Headings B2A and B2H  In a method of recovering metal scrap from articles composed of a number of different metals, e.g. scrap machinery, the articles are broken up into pieces by subjecting them to impact, brittle material which is broken into small pieces by the impact is separated from the larger pieces of less brittle material by causing the smaller pieces to pass through a sieve which retains the larger pieces, and the larger pieces are subjected to further repeated impact and tearing and are then conveyed by centrifugal action away from the sieve.  Pieces of scrap to be broken are supplied through a duct 2 to the periphery of a hammer mill, rotor 3 having pivotable hammers 4. The rotor is surrounded by a housing 6 which over a lower portion is constructed as a sector-shaped grating 9 having openings 10 of relatively narrow mesh. A vertical shaft 11 is attached to the housing and has its top end fitted with a grating 12 having openings 13 of larger diameter than the openings 10. The pieces of scrap introduced through the duct 2 are first subjected to impact by the hammers 4. Due to their great brittleness components made of cast rion are broken down easily into small pieces which pass through the grating 9. The other components of the scrap which are less brittle, e.g. those made of copper, aluminium and chromium, are subjected to repeated impact and tearing by the hammers 4. Pieces are eventually formed from these components and are thrown centrifugally upwards by the rotor 3 through the shaft 11. Pieces which can pass through the grating 12 enter a hood 14 and are removed through an outlet 15. Larger pieces fall back on to the rotor to be further reduced by the hammers. High-alloy steel components which cannot be broken up are removed by swinging a pivotable flap 17 inwards to the position shown in chain-dotted lines so as to deflect these components directly into the hood 14. When the scrap contains carbon-steel components the brittleness of the latter may be increased by cooling the scrap. This is done by feeding scrap pieces 27 via a hopper 25 into a receiver 24 where they are compressed into bales 18 between a plunger 26 and a slide 22. After the formation of each bale the slide 22 is raised and the bale is pushed into a chamber 19. When a sufficient number of bales have been pushed into the chamber the slide 22 is lowered and a refrigerant, e.g. liquid nitrogen, is supplied through nozzles 23 to the chamber to cool the bales which are subsequently supplied to the rotor periphery by a plunger 21.

Patent GB-647897-A (GB)
Title: Improved process for the colouration of textile materials of organic derivatives of cellulose
Filed: 1947-07-28
Abstract: Textile materials of cellulose acetate or other organic derivative of cellulose are coloured by applying a leuco vat dye in an aqueous medium which swells the cellulose derivative, the swelling action being due at least in part to the presence of a water-miscible organic base.  Pyridine is the preferred swelling agent, and may be used in the proportion of 15-25 per cent by weight of the medium; other suitable bases are methyl- and other alkyl-pyridines, piperidine, N-alkyl-piperidines, benzylamine, ethylene diamine and N-diethyl-ethylene diamine.  Hydroxy-amines and quaternary bases are not suitable.  A further water-miscible organic liquid may be present, preferably an aliphatic hydroxy or halogen compound, ketone, ester or ether, and preferably containing two such polar groups. Diacetone alcohol is preferred; other suitable compounds are ethylene glycol monoacetate and its methyl ether, glycerol mono- or di-acetate, ethylene glycol mono methyl or ethyl ether, ethyl lactate, ethylene chlorhydrin, ethylene methylene ether and tetramethylene oxide.  Monohydric alkanols can be used but the stability of the dye liquid may be impaired.  Inorganic swelling agents, such as thiocyanates, may be present, together with wetting agents and a formaldehyde sulphoxylate.  When the material is to take up the dye substantively, the components of the medium are present in such a proportion that only a moderate swelling action takes place, e.g. 15-20 per cent of diacetone alcohol with 5-10 per cent of pyridine (the two together not exceeding 25 per cent) when working at 50-60 DEG  C.  For mechanical impregnation, e.g. padding or printing, or a short immersion followed by centrifuging, a higher proportion of organic liquid is used, and a thickness is preferably added, e.g. a water-soluble cellulose ether.  After application of the dye liquid, the material is washed, the leuco dye is oxidized in the normal way, and the material hot-soaped and/or steamed to develop the shade and increase the light fastness.  The process is applicable to vat dyes containing two or more anthracene nuclei, e.g. those derived from dibenzanthrone, isodibenzanthrone and indanthrone, and those obtained by ring closure of Bz - 1 - benzanthronyl - 1 - aminoanthraquinones and a a 1-di- and poly-anthrimides.  Examples show the application of vatted Caledon Jade Green B, Caledon Red X 5B, Caledon Brown G and Caledon Brilliant Blue 3G are also mentioned as suitable.  The use of esters of leuco-vat dyes and the process of Specification 479,867 are disclaimed.  According to the Provisional Specification, hydroxyalkylamines, quaternary bases and difficultly-soluble organic bases may be used when an additional water-soluble organic swelling agent is present.

Title: Transistor relay circuit

Abstract: 875,247. Transistor switching circuits. STANDARD TELEPHONES & CABLES Ltd. June 19, 1959 [June 25, 1958], No. 21117/59. Class 40(6) [Also in Group XL(b) ] A switching circuit for converting single current signals to double current signals comprises two transistors of the same conductivity type arranged in series between the positive and negative terminals of a supply, an output circuit connected between the junction of the transistors and the centre tap of the supply, a resistor connected between the transistors and arranged so that the transistors conduct alternatively, an input circuit connected to one of the transistors comprising a transistor of opposite conductivity type and a positive feedback circuit between an output terminal and the input transistor. The Figure shows two transistors TS1, TS2 connected between the positive and negative terminals u of a supply source and output terminals a, b connected to the junction of the transistors and the centre tap of the source. Transistor TS1 is controlled by the current through R6 so that when transistor TS1 is conducting transistor TS2 is cut off and vice versa. Input telegraph signals are applied to transistor TS1 through a transistor TS3 of opposite conductivity type so that when the input transistor is conducting transistor TS1 is also conducting and TS2 cut off the output terminal a thus being connected to the positive battery terminal. When the input transistor is cut off transistor TS1 is cut off and TS2 conducting so that the output terminal is connected to the negative source. Positive feedback via a resistor R1 speeds the changeover between the conducting conditions. In a further embodiment (Fig. 2, not shown) temperature stability is improved by connecting a temperature sensitive resistance network between the emitter transistor TS1 and a resistor in the emitter circuit of transistor TS3. In addition, the transistors are protected against excessively high voltages which may be produced if the load is inductive or if the output line is faulty by connecting a capacitor and a voltage dependent resistor across the output terminals. The resistors R4, R6 and R8 may be reduced or eliminated if they are supplemented or replaced by diodes (Fig. 3, not shown).
