Patent GB-624604-A (GB)
Title: Improvements in or relating to esters of chloroformic acid and the preparation thereof
IPC: C07C69/96
Filed: 1944-07-06
Abstract: Esters of chloroformic acid are produced by reacting a compound having an alcoholic hydroxyl group with liquid phosgene or phosgene in solution, the phosgene being present in excess of the stoichiometric amount required for reaction with the alcoholic compound, allowing unreacted phosgene to vaporize, condensing the vaporized phosgene and returning the condensed phosgene to the reaction mixture.  After the reaction begins additional amounts of the alcohol and phosgene are introduced into the reactor, preferably in continuous streams, a considerable excess of phosgene being always maintained in the reaction vessel.  The reaction temperature is preferably between 15 DEG  and 25 DEG  C. and is controlled by adjusting the relative rates at which the alcohol and phosgene are introduced, thus, if the temperature becomes too high the ratio of phosgene to alcohol is increased and vice versa. The reaction may also be effected by introducing phosgene, preferably gaseous phosgene, into a preformed quantity of the chloroformate of the alcoholic compound having phosgene dissolved therein, then introducing phosgene, preferably gaseous phosgene, together with additional alcohol at such a rate as to maintain an excess of phosgene, allowing the unreacted phosgene to vaporize, condensing the vaporized phosgene and returning it to the reaction mixture.  The reaction may be carried out continuously. In examples: (1), (2) and (3) ethyl alcohol, isopropyl alcohol and allyl alcohol respectively are introduced into liquid phosgene in a glass reactor equipped with a brine cooled reflux condenser, the phosgene vapour is condensed and returned to the reactor and further amounts of the alcohol and phosgene are introduced, the flow and relative amounts of phosgene and alcohol being adjusted so as to maintain the reaction temperature between 15 DEG  and 25 DEG  C., ethyl, isopropyl and allyl chloroformates respectively are obtained; (4) and (5) gaseous phosgene is introduced into a reaction vessel charged with ethylene glycol bis-(chloroformate) and diethylene glycol bis-(chloroformate) respectively, and ethylene glycol or diethylene glycol then added, the temperature being controlled as in (1).  Other compounds containing an alcoholic hydroxyl group which are specified are monohydric alcohols, e.g. propyl-, butyl-, isobutyl- and benzyl-alcohols; glycols such as propylene glycol, trimethylene glycol; glycerol, 2-nitro-propanol-1, methyl-tert-butyl carbinol; ethyl lactate and methyl glycollate.

Abstract: 475,111. Train - actuated contact devices. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. May 13, 1936, No. 13549. Convention date, May 31, 1935. [Class 105] The increase of flux with the entry of a train wheel into an air gap of a magnetic circuit provided by one or more cores with energizing windings thereon actuates an electric-contact-making armature included in the magnetic circuit. Two such devices may have their armatures mechanically interlocked so as to provide a directional device. The device may comprise two energized cores 4, Fig. 2, of which only one is seen in the elevation, with a bridging armature 15 slightly spaced from two adjacent core ends, the other two core ends having spring-urged polepieces 8 pivoted thereon which are adapted to engage the face of a passing wheel C. The rail clamp 23 and the core supports 21 are non-magnetic. A guard rail B positions the wheel to prevent damage to the device and non-magnetic stop brackets 14 limit the outward movement of the pivoted polepieces 8. In the device shown in Fig. 4, only one energized core 27 is used and the rail forms part of the magnetic circuit X shown by the arrows. The core 27 is supported by a non-magnetic arm 34. Fig. 6 shows the interlocking arrangement to give a directional effect when two adjacent devices of the form shown in Fig. 4, are used. The two armatures 29A, 29B only are shown. When armature 29A is attracted the end 40 of the arm 38 moves downwardly and acting on an arm 41 causes an upright rod 42 to move under the end of the arm 45 of the other armature 29B. Thus this armature 29B is substantially prevented from moving when it is attracted ; sufficient movement however is permitted for .the hook end of the arm 45 to engage over the upright rod 42 whereby the interlocking mechanism is held until the second armature is no longer attracted.
