Filed: 1928-09-07
Abstract: 322,526. Automatic Telephone Manufacturing Co., Ltd., and Ostline, J. E. Sept. 7, 1928. Automatic exchange systems. - The circuit of a. pendulum impulse generator is arranged so that after the initial energization, the maintaining magnet is energized only when the pendulum is in the position remote from the magnet. Earth connected to lead 10 energizes I to attract the pendulum which when fully attracted completes the circuit for slow release relay S. Relay S energizes breaking the circuit of I and releasing the pendulum. In its remote position the pendulum completes at 12 the circuit of the magnet I and is attracted, whilst. in the attracted position springs 11 are closed to maintain the energization of S, which holds up throughout the train, and also to transmit earth over the line 13 to give the pulse required.

Patent GB-482352-A (GB)
Title: Improvements in the manufacture and production of polyamino carboxylic acids and their derivatives
Filed: 1936-09-28
Abstract: Polyamino carboxylic acid nitriles containing at least two nitrile radicles, or the corresponding acids are obtained by reacting hydrocyanic acid and aldehydes or ketones on primary or secondary polyamines and if desired hydrolyzing the nitriles.  If the saponification is effected with acids in the presence of alcohols, esters of the polyamino acids are obtained.  The process may be effected in two or more stages, using different aldehydes or ketones if desired, Suitable polyamines are ethylene and propylene diamines and diethylene triamine and their substitution products, which may contain hydroxy, mercapto or other groups, such as diaminodiethyl ether.  Diamines containing a radicle of high molecular weight such as octadecyl triethylene tetramine or oleyl pentmethylene hexamine may also be used.  Suitable aldehydes and ketones are formaldehyde, acetaldehyde, propionaldehyde, acetone and oleyl aldehyde.  Alkaline substances such as cyanides, which may be produced in situ are suitable catalysts.  The nitriles may be reduced to the corresponding amines.  In examples: (1) to an aqueous solution of ethylene diamine are added hydrocyanic acid and a solution of calcium cyanide, and formaldehyde solution is added at 20-25 DEG  C.; the product is saponified by sodium potassium or barium hydroxide or sulphuric or hydrochloric acid; (2) as in example 1, but using acetaldehyde; (3) as in example 1 but using diethylene triamine or triethylene tetramine; (4) hydrocyanic acid and formaldehyde are reacted with the nitrile of ethylene diamine diacetic acid obtained in example 1; products containing four different acid radicles can be made in this manner, or, if diethylene triamine or triethylene tetramine are used, products containing 5 or 6 different acid radicles may be made; (5) the process of example 1 is effected in two stages, using first formaldehyde and then acetaldehyde or vice versa.  Specifications 388,874 and 460,372 are referred to.  Octadecyl triethylene tetramine is obtained by reacting sodium octadecyl sulphate with triethylene tetramine.  Oleyl pentamethylene hexamine is obtained by reacting sodium oleyl sulphate with pentaethylene hexamine.

[Also in Group XXVII] A dynamometer for testing the power output of internal combustion engines comprises a drum-like structure 1 in which are mounted the engine under test 33 and a dynamometer 5 measuring the power developed. The structure is rotatable about a horizontal axis passing through its centre of gravity, and a motor 15, Fig. 3, for starting and running in the engine under test is mounted on an independent stationary support. The output from the engine 33 is transmitted by a Cardan shaft 11 to a gear-box 14 and then via a Cardan shaft 12 to a dynamometer 5. The gear box 14 transmits the engine output through a shaft 13 coupled between the two Cardan shafts 11, 12 as shown in Fig. 5. Mounted on the shaft 13 is one of a pair of bevel wheels 22 freely rotatable on a sleeve terminating in one member of a clutch 24. The other member 25 of the clutch is keyed to, and slidable on, the shaft 13 by means of keys 26. In operation the engine 33 is started by the motor 15 by means of the drive through a variable speed drive 16, shaft 36 and Cardan shaft 18 and through the bevel gears 21 22 and clutch 24, 25, which is then disengaged automatically by means not shown. The power output from the engine is then transmitted to the dynamometer as described above. The position of the engine and dynamometer with respect to the horizontal axis may be varied by means of a ratchet handle 32, Fig. 3, co-operating with a ratchet gear 31. The drumlike structure may then be clamped in any desired position by clamps 10 which clamp the rollers 7 on which the structure is supported. The starting motor 15 and variable speed gear 16 is supported on a separate fixed support 35.

Abstract: A process for reducing the solvent content of filamentary material having a basis of a carboxylic acid ester of cellulose, particularly cellulose triacetate having an acetyl value of 59.5 per cent or more reckoned as acetic acid and containing at most 0.2 free hydroxyl groups per anhydroglucose unit, and which contains solvent consisting of methylene chloride with or without a lower aliphatic alcohol, comprises either evaporating solvent from the material after applying water, preferably in the form of a lubricating emulsion in an amount of 2-25 per cent of the solvent-free weight of the material, or by evaporating solvent in an atmosphere of high relative humidity, generally at least 15 per cent, and preferably at least 25 per cent relative humidity.  The solvent evaporation in either case is most desirably carried out at 65-100 DEG  C. for a period of 1-10 minutes. The filamentary material to be treated is preferably in the form of a tow of total denier of 45,000-1,000,000, with a filament denier of 1.5-50. Methylene chloride, which is evaporated from the filaments, may be recovered and re-used for the spinning process.  If the process employed is the one wherein the filaments are treated with the water in the liquid state, it is advantageous to dry the filaments after treatment by evaporating the solvent under the same conditions of high humidity as in the other process.
