Title: Improvements relating to the distillation or consolidation of coal or other materials by the application of heat
IPC: C10B7/00
Filed: 1937-10-07
Abstract: 507,236. Coking or heat - treatment of solid materials. DAVIDSON, T. M. Oct. 7, 1937, No. 27278. Addition to 475,727. [Classes 51 (ii) and 55 (i)] In a rotary retort of the kind described in the parent Specification in which the charge is heated while compressed into annular channels on the periphery of a cylindrical drum, the drum casing 1 is formed from metal plates jointed to leave gaps 2 between their adjacent-edges. The annular.members 3 forming the lateral walls of the channels have a clearance from the periphery of the casing and have inwardly extending projections 3<1> which engage in the gaps 2. The scraping tools 4 maintain the lateral walls in spaced relationship without additional spacing means, and these tools are strengthened by webs 7. The compressing roller 15 is caused to rotate against supporting rollers 16 mounted at the ends of arm 19 secured to the' hopper 8. A concentric inner flue 23 is formed by a series of segmental rings 24 with radial parts 25 and tongue pieces 26 which divide the annular space around them into segmental channels 29. Strips 30 of wedge like cross section are engaged by the radial elements 25 which are jammed against the casing 1 to prevent relative movement, should unequal expansion due to heat cause the flue 23 to become free within the casing 1. Heating gases from a furnace 40 flow through a flue 41 to the inner flue 23 of the drum through which they pass, and return through channels 29, an annular chamber 45, a vertical chamber 46, Fig. 9, and recuperator 47 communicating with a chimney. A part of the hot gases may be recirculated and caused to pass through an opening 55 into flue 41. The heating gases may however be caused to pass first through the annular spaces 29, and return through the central flue 23.
Patent GB-776044-A (GB)
Title: Improved polymeric sulfochlorides
IPC: G03C7/29
Filed: 1952-05-06
Abstract: Polymeric sulphochlorides of the type described in Specification 776,043 are prepared by reacting polymers of the form (-A-)n, where A is a divalent radical containing an aromatic group and n is an integer at least equal to 3 in solution in organic solvents with sufficient excess of chlorosulphonic acid to keep the product in solution in at least the early stages of the reaction.  Exemplified polymers are polystyrene, polyvinylnaphthalene and copolymers of styrene with maleic anhydride, diethyl maleate and ethyl vinylsulphonate.  Suitable solvents are halogenated or unhalogenated saturated aliphatic hydrocarbons, e.g. carbon tetrachloride, trichloroethane, ethylene chloride and heptane.  Preferably at least two equivalents of chlorosulphonic acid are used and the products precipitated by adding excess solvent.  In examples the sulphochloride solution is filtered before precipitation and the precipitate purified by dissolving in acetone or benzene and reprecipitating with benzene or isopropanolmethanol mixtures. The products may be used as intermediates in the preparation of colour couplers in colour photography.  German Specification 503,923 and 580,366 and U.S.A. Specification 2,445,569 also are referred to.
Patent GB-535386-A (GB)
Title: Improvements in electric wave repeater circuits
IPC: H04B3/20
Filed: 1939-10-06
Abstract: 535,386. Two-way transmission. STANDARD TELEPHONES & CABLES, Ltd., MEERS, R. A., COCKBAIN, E. R., and PROBERT, G. O. Oct. 6, 1939, No. 27372. [Class 40 (iv)] In a two-way repeater employing voltagecontrolled attenuators AP 1-4 in the transmission paths a limiting amplifier LA is inserted in the input of one path to prevent the risk of false operation by peaks of current which may pass through the opposite path. The arrangement is suitable for a repeater situated at or near one end of a line, when the speech currents from the near end are much stronger than those from the far end. The attenuators AP1, 3 are normally in a low loss condition, while the attenuators AP2, 4 are in a high loss condition. Speech currents in the upper path operate through a control circuit VOD1 connected to the output of API to reduce the loss of AP2 and increase that of AP3 and speech currents in the lower path exercise ' a similar control through a circuit VOD 2. The circuit VOD1 feeds a valve VI, which derives anode current through a resistance R14 from a battery which supplies also a potentiometer comprising resistances R15-17. The gain of V1 is stabilized by a feed-back through a transformer T4 and rectifier X3 to the control grid. The control voltage for AP2 is obtained from the points M, K, while that for AP3 is obtained from the points M, L, and in the normal condition M is at a lower potential than K, L. When speech currents enter the circuit VOD1, however, the anode current of V1 is reduced substantially to zero, and M becomes a higher potential than K, L. A shunt condenser C7 slightly delays the control on AP2. A resonant circuit L1, C3 renders the control circuit VOD1 less sensitive at the higher frequencies.
