Title: Communications switching systems
IPC: H03K17/62
Filed: 1971-11-16
Abstract: 1363464 Automatic exchange systems; duplex transmission WESTERN ELECTRIC CO Inc 16 Nov 1971 [16 Nov 1970] 53033/71 Headings H4K and H4P Interference between oppositely directed signals in a two-way simultaneous transmission system employing a single conductive path is reduced by mismatching at both ends of the conductive path such that in one direction of transmission the signal is transferred from high impedance circuitry to low impedance circuitry thereby involving relatively large current variations as compared with very small voltage variations on the conductive path, and in the other direction of transmission the signal is transferred from low impedance circuitry to a high impedance circuitry thereby involving relatively large voltage variations as compared with very small current variations on the conductive path. The system is described with reference to the simultaneous transmission of pulses from digit sources 62, 52 to digit detectors 53, 63 respectively via two crosspoint switching networks 10, 20 employing thyristors at the crosspoints, and a junctor 40, transmission through each switching network taking place according to the arrangement outlined above. The digit source and detector at each end of the system are coupled to a single input terminal of the corresponding network by a line terminal circuit which presents its emitter impedance to the network, this impedance being relatively low. The output terminals of the networks are connected to respective bases of transistors 41, 41<SP>1</SP>, these transistors presenting their high impedance base circuits to the respective switching networks. The outputs of these transistors are then coupled to the output terminals of the respective second networks via respective Zener diodes 45<SP>1</SP>, 45 and common emitter transistor circuits 44<SP>1</SP>, 44 which present their high collector impedances to the networks. It can be seen, therefore, that transmission across each network in the two directions is from a high to a low impedance, and from a low to a high impedance respectively. The Specification contains a theoretical analysis of the operation which leads to two conditions for the interference between the two directions of transmission to be minimized. A condition is also derived for the gain through the system to be unity. The system must also be arranged so that the holding current through the thyristor cross-points is sufficiently large that the reversely transmitted signals do not cause the current to drop below the minimum holding current thereby turning off the thyristor.
Patent GB-1088829-A (GB)
Title: A process for producing ferric dextran complexes and solutions thereof for therapeutic use
IPC: A61K31/295
Filed: 1965-12-15
Abstract: In a process for making a ferric dextran complex wherein a ferric compound is complexed with a dextran compound, the reaction product is precipitated as one or more fractions with different ferric content, one of the fractions from the first complexing step is subjected to a second complexing step with ferric compound. The dextran compound may be depolymerized dextran, dextran glucoside or raw dextran.  The intrinsic viscosity of the dextran compound is desirably 0.025-0.25 but raw dextran of intrinsic viscosity up to 0.75 can be used if the complex-forming conditions are such as to degrade the dextran. Any ferric salt which forms ferric hydroxide in presence of a base, and dextran, may be used.  The complexing reactions may be carried out at temperatures up to 100 DEG  C., the molar ratio of glucose units to iron preferably being less than 2. When dextran glucoside is used, this molar ratio may be 1.1-4.0. After the first complexing step, desirably carried out at pH 1.1-2.3, ferric ions may be removed from the reaction mixture by dialysis, ion-exchange or repeated precipitation and dissolution of the ferric dextran complex. The dextran in the complex may then be degraded by autoclaving at, e.g., 110-120 DEG  C., and residual ferric ions may then be complexed by adjusting the pH of the reaction mixture to above 10 and again autoclaving.  Fractional precipitation of the complex is effected by use of acetone or an aliphatic alcohol.  The fraction used for the second complexing step (carried out under acid conditions) may have a ferric content of 0.1-22%.  The product of this second complexing step may itself be fractionated, the fraction of higher ferric content (containing up to 42% Fe) being used for low toxicity, low viscosity, therapeutic solutions, the lower ferric content fraction being recycled to the process.ALSO:A therapeutic composition comprises an aqueous solution of a complex of ferric iron with raw dextran, depolymerised dextran, or dextran glucoside, containing up to 42% (dry weight) of iron (see Group C3).  The low viscosity and low toxicity solution (pH 5.5-8.5) may contain up to 10% of ferric iron and may be made isotonic with blood fluids.  In Examples, solutions of ferric-dextran glucoside complex and ferric-dextran complex containing 8-10% Fe, and having viscosities of 9-15 cps at 25 DEG C. and LD50 values of 890-1150 mg Fe/kg assayed by intravenous injection in mice.

Heading C2C. α,#-Mono-olefinically unsaturated esters and nitriles are reductively dimerized in a medium capable of providing reactive hydrogen by reacting an alkali or alkaline earth metal amalgam with said medium in the presence of at least one additive promoting the hydrodimerization reaction characterized in that the amalgam phase is maintained in turbulent motion corresponding to an energy dissipation wave number greater than 100 cm.<SP>-1</SP>. The process may be operated batchwise or continuously, suitable forms of apparatus being described. The turbulence may be effected, for example, (a) by providing intense agitation in the region of intimate contact between the amalgam phase and the phase containing the monomer, e.g. by employing a stirrer at the interface or separate stirrers in either phase may be used, optionally with baffles; (b) by agitating the two phases by jet mixing; (c) by passing the aqueous phase upwardly through a sieve tray or bubble capcolumn containing a layer of amalgam on each tray; or (d) by employing fluidized bed techniques wherein the fluidized bed suitably consists of between 90% and 10% v/v. of amalgam. The additives which promote the hydrodimerization reaction, may be alkylated cations, e.g. ammonium, phosphonium or sulphonium cations, in the form of their salts, or certain polar aprotic solvents, e.g. sulpholane, dimethylsulphoxide, formamide, dimethyl formamide or dimethylactamide. The medium capable of forming hydrogen with the amalgam may be water or an alcohol and organic solvents (other than those specified above) may be present. The reaction is preferably effected at an apparent pH between 7 and 11À5 which may be regulated by the addition of gaseous carbon dioxide, a polymerization inhibitor may be present and the reaction may suitably be effected between 0‹ and 60‹ C. In specific examples, acrylonitrile is hydrodimerized to adiponitrile, some propionitrile and some trimer also being obtained.
