Filed: 1928-03-15
Abstract: 315,687. Allan, J. E. March 15, 1928. Divided on 316,111, [Class 38 (iii), Electric motor control systems &c.]. Dynamos and motors, cooling.- The casing of a dynamo-electric machine is provided with air inlet and outlet openings which are open in normal running so that the casing forms a ventilated or pipe ventilated enclosure but are automatically closed when the machine is stopped so that the casing forms a total enclosure, the closure means being interlocked with the control switchgear of the machine or with the rotor. As shown applied to a combined winch motor and its controlling motor generator as described in Specification 316,111, the motor generator A B is enclosed in the casing R to which is bolted the casing c<1> of the main motor C. In an opening in the casing R there is provided an air control valve casing S in which work two pistons T, T<1>, connected together and linked to the handle t' of starter F<2> for the main motor or motor generator. When the starter handle r<4> is in the full on position, the piston valves occupy the dotted line positions z z and air enters the valve casing through the port 8<SP>2> from the valve casing, the air flows through an inlet port s', conduit s' and an opening in a baffle-plate s<8> into the main motor casing through which it flows in the direction of the arrows x, x'. Passing through an opening s<9> between the casings c<1> and R the air divides into two streams x<2>, x<3> in the motor generator casing and enters the valve casing through an exhaust port s<5> which is in communication with the atmosphere by an outlet port s'. Circulation of the air is caused by a fan located between the two armatures of the motor generator. When the starter is moved to the " off " position, the valves occupy the full line position y y, and the exhaust port s<5> is in direct communication with the inlet s<4> so that the machine casing is totally enclosed- The starter F<2> may be provided with a " novolt" release. In a modification applied to a motor, Fig. 6, the motor casing U is provided with an air control casing V formed with inlet and exhaust ports v<1>, v<2>. A valve plate or door v<3> adapted to close the ports is connected by a link w<4> to the handle w<2> of the starting or control gear of the motor so that the ports are closed when the machine is stopped and opened when the machine is running. Instead of interlocking the doors or valves with the control switchgear, they may be interlocked with a centrifugal device or a cam may cause the valves to open and they may be kept open by a detent electromagnetically controlled by a current which ceases when the machine stops and releases the detent. Or the door may be coupled to a switch which has to be closed to start the motor and the switch may be automatically opened when the current supply is cut off and may, in opening close the valve or door. Air circulation may be effected by providing a fan at one end or both ends of the machine-

Title: Improvements in and relating to alkanolamines
IPC: C07C215/06
Filed: 1945-07-13
Abstract: Alkanolamines are prepared by hydrogenating one or more cyanhydrins of aliphatic aldehydes or ketones in the presence of at least four times their weight of an organic solvent inert to the reactants and products and in the presence of a proportion of a hydrogenation catalyst amounting to at least 250 per cent by weight of the cyanhydrins.  Examples of cyanhydrins are those of formaldehyde, acetaldehyde, n- and isopropanal, n- and isobutanal and of dimethyl ketone, methyl ethyl ketone, dipropyl ketone and methyl propyl ketone.  Suitable solvents are methanol, ethanol, the propanols and butanols, dimethyl ether, diethyl ether, methylal, dimethoxy methyl ether, ethylal, dioxolane and di-alkyl amides such as dimethyl formamide.  Catalysts mentioned are nickel, cobalt, nickel-cobalt and copper chromite.  In examples: (1) formaldehyde cyanhydrin in methanol, isobutanol or dimethyl ether is converted into a mixture of mono, di and triethanolamines, N-methyl mono and diethanolamines and b -hydroxyethyl ethylene diamine in proportions varying according to the conditions; (2) acetaldehyde cyanhydrin in methanol is converted into mono and diisopropanolamines and (3) acetone cyanhydrin in isobutanol is converted to isobutanolamine, the catalyst in all cases being obtained by extracting 85 per cent of the aluminium from a nickel-aluminium alloy containing 48 per cent nickel; (4) formaldehydecyanhydrin in methanol is passed continuously into a heated silver lined reactor with hydrogen under pressure, the reactor containing the same catalyst with results as in (1).  A comparative experiment is described following the procedure of (1) but with less than 250 per cent of catalyst, the formation of alkanolamines being negligible.
