Abstract: 215,455. Robinson, J., and Derriman, W. H. Feb. 12, 1923. Aerials ; thermionic amplifiers and detectors; coupling aerial and detector circuits.-The mains of an electric supply system are utilized both as the receiving aerial and as the source of current for the filament and plate of one or more valvereceivers, or to give the necessary potential bias to a crystal receiver. Fig. 1 shows the circuit arrangement for a direct-current supply. The aerial circuit comprises one or both of the mains 3, 4, blocking condensers 9, tuning condenser 10, inductance 11, blocking condenser 19 and earth. The current supply for the filament is tapped off from a potentiometer 15, whilst the plate potential is derived from a second potentiometer 14, preferably shunted by a lamp 24. Chokes 16, 17 and one or more condensers 18 smooth out generator noise and bar the passage of highfrequency currents. Fig. 2 shows a two-valve set connected to an alternating-current supply. The aerial comprises the main 4, blocking condenser 9, tuning condenser 10, inductance 11 and earth. Filament current is supplied through a transformer 30 and a resistance 31, shunted by condensers 32 and connected at its mid-point to the aerial inductance 11. The plate voltage is derived from a rectifier 33, the two plates of which are fed through a transformer 34 whilst the filament is incandesced through a transformer 35. Chokes 36, 37 inserted in the plate supply and shunted by condensers 38 serve to exclude any ripple. In a modified arrangement, the main supplying current to the filament ie also used as the aerial down-lead. The chokes 16 and potentiometers 14, 15, Fig. 1, may be combined into one continuous coil from which suitable tappings are taken to the plate and filament, a movable core being utilized to adjust the choking effect.

Abstract: 124,039. Beilby, Sir G. T. March 12, 1918. Carbonizing-furnaces.-Coal or other bituminous or organic material to be carbonized is spread in a thin layer on trays carried round horizontally by a rotating frame within a gas-tight casing. The trays 10 are mounted in a frame 3 carried by a vertical shaft 4 passing through a gas-tight bland 6 into a closed casing 2. The casing 2 is enclosed within a chamber 1 and is supported in such a manner that the products of combustion of the heating- burners, which are arranged to render the inner surface of the dome of the chamber incandescent, may have. access to the whole of its surface. Material is fed on to the trays through a hopper 17, the lower edge of which acts to spread out the material into a uniform layer. The speed of rotation is such that carbonization is completed in rather less than one revolution. The trays 10 are pivoted on radial rods 11 and are arranged to tend to hang vertically. They are kept horizontal by rollers 12 bearing against a rail 13. When the tray reaches the discharging position, the roller 12 comes to a gap in the rail. The coke &c. is discharged through crushing rollers 19 into a gas-tight shoot 20. The tray is then automatically restored to the horizontal position and passes under the feeding hopper 17. Gases or steam may he fed into the casing 2. Gases are withdrawn through pipes 27.
Patent GB-470346-A (GB)
Title: Manufacture and application of new quaternary ammonium salts
Filed: 1936-02-12
Abstract: Quaternary ammonium salts are obtained by reacting an alkyl ester of an inorganic acid or of an organic sulphonic acid with an ester of the formula ROOCArNXX<1>, where R is an aliphatic hydrocarbon radicle of 10--20 carbon atoms, Ar is a residue of the benzene series, and X and X<1> are lower alkyl (methyl to butyl) radicles.  Specified esters of inorganic acids or of organic sulphonic acids are dimethyl sulphate, diethyl sulphate, ethyl bromide, methyl iodide, methyl benzenesulphonate, butyl benzenesulphonate, and ethyl p-toluenesulphonate.  The alcohol from which the radicle R is derived may be dodecyl, tetradecyl, hexadecyl, octadecyl or oleyl alcohol, and these may be pure products or crude materials obtained by saponifying waxes such as spermaceti, or by reducing the acids of fats and oils such as coconut oil and palm oil.  The quaternary ammonium salts form foaming aqueous solutions and are useful as additions to alkaline vats for dyeing cellulosic materials such as cotton or viscose artificial silk.  Examples are given of the manufacture of products from (1) cetyl p-dimethylaminobenzoate and dimethyl sulphate; (2) dodecyl p-dimethylaminobenzoate and dimethyl sulphate; (3) cetyl p-diethylaminobenzoate and dimethyl sulphate; (4) oleyl p-dimethylaminobenzoate and dimethyl sulphate; (5) cetyl 2-methyl-4-diethylaminobenzoate and dimethyl sulphate; (6) cetyl p-dimethylaminobenzoate and diethyl sulphate; (7) cetyl p-methylbutylaminobenzoate and dimethyl sulphate; and (8) cetyl p-dimethylaminobenzoate and methyl p-toluenesulphonate; the reaction is generally effected at 90--100 DEG  C. in the presence or absence of a solvent.  In examples of the use of the products, cotton yarn or fabric or viscose artificial silk piece material is treated in a vat containing sodium hydrosulphite, caustic soda; and (9) Caledon jade green and the product of example 1; (10) Caledon brilliant purple RR and the product of example 1 or 6; (11) Caledon yellow G and the product of example 3; (12) Algol pink B and the product of example 4; (13) Helindone red 3B and the product of example 2; (14) Caledon jade green and the product of example 5; (15) Caledon jade green and the product of example 7; (16) Caledon blue RC and the product of example 2; (17) Indanthrene brilliant violet 4R and the product of example 8; in each example, the treatment is followed by oxidation and treatment with boiling soap solution.  Specification 436,942 is referred to. Cetyl p-dimethylaminobenzoate is obtainable by reaction of p-dimethylaminobenzoyl chloride with cetyl alcohol in the presence of dimethylaniline.  Dodecyl p-dimethylaminobenzoate is obtainable by treating dimethylaniline with phosgene to produce a solution of p-dimethylaminobenzoyl chloride in dimethylaniline, and heating the product with dodecyl alcohol.  Cetyl p-diethylaminobenzoate, oleyl p-dimethylaminobenzoate, cetyl 2-methyl-4-diethylaminobenzoate, and cetyl p-methylbutylaminobenzoate are similarly obtainable.

The screws 16 also are associated with steel bushings. After removal of the screws 13, 16 the frame may be withdrawn horizontally from its cradle, and to facilitate replacement, the bushes 17 and the opposed faces of the bushes 18 have horizontal tongue and groove connections, which serve also to relieve the shearing stress, due to the cutting operation, on the screws 13. The cradles 12 are guided in grooved guides 22, the crankshaft 26 being connected by rods 25, 25<1> to rods 24, 24<1> rigidly secured to the cradles 12, the rods 24, 24<1> being off-set towards the centre line to minimize the side thrust of the rods 25, 25<1>. The rods 24, 24' pass through stuffing-boxes 31 each having two glands, the upper for excluding crumbs and to prevent the escape of oil and the lower, which is perforated, to permit oil which collects between the glands, to return to the crankcase. An oil pump is driven by a worm 33 on the crank shaft, the oil being forced by way of, an adjustable relief valve to the bearings 40, 42. If desired, oil pipes leading to the pins 28 may be clamped to the rods 25, 25<1> and oil may be conducted to the guides 22. The oil returned to the sump from the relief valve is passed through a filter. An oil pressure gauge 45 and a temperature gauge 47 are provided. The slicer is slidably arranged on guides 56 of a packer, so that it may be slid into or out of position according to whether sliced or unsliced loaves are to be wrapped. The drive is effected through a belt driven shaft 50 having a coupling member with radial projections which engage radial recesses in a soft rubber coupling member 53. When the slicer is slid into the operative position, radial projections on the face of a coupling member 52<1> on the crank shaft, engage radial recesses in the opposed face of the member 53. A switch in the motor circuit may be operated by the sliding of the slicer.
