Patent GB-601511-A (GB)
Title: Improvements in or relating to the production of chloronitriles
Filed: 1945-12-05
Abstract: Tetrachloro succinonitrile is obtained by reacting, in the vapour phase, chlorine with succinonitrile or its unsaturated chloro-derivatives obtained from the reaction of succinonitrile in the liquid phase with chlorine.  Thus, the mixture of chlorinated derivatives comprising monochloro- and dichloro-maleo nitriles and fumaronitriles obtained from the reaction of molten succinonitrile with chlorine as described in Specification 601,510 may be heated with chlorine in the vapour phase.  The reaction may be effected at temperatures of 200 DEG  to 550 DEG  C. and a surface-active agent such as activated carbon, activated alumina or silica gel may be used as catalyst.  When a surface-active agent is employed, the temperature range is preferably 200 DEG  to 350 DEG  C. and in the absence of surface-active material temperatures of 350 DEG  to 500 DEG  C. are preferred.  It is desirable to employ an excess of chlorine over the amount theoretically required to convert the succinonitrile used into tetrachloro succinonitrile. In examples, tetrachloro succinonitrile is obtained by reacting: (1) succinonitrile in the vapour phase with a substantial excess of chlorine at 350 DEG  C.; (2) chlorine with succinonitrile in a reaction zone packed with active carbon at 200 DEG  to 250 DEG  C.; (3) and (4) a mixture of monochloro- and dichloro-maleo- and fumaronitriles with excess chlorine in a tube packed with activated charcoal at 250 DEG  to 300 DEG  C.

Abstract: 717,819. Washing machines. SOC. ANON. DES USINES J. GALLAY. Dec. 30, 1952 [Nov. 7, 1952], No. 32983/52. Class 138 (2). In a washing machine having a centrifugal pump 11 below the tub 1 for circulating water from the bottom of the tub to one or more inlet nozzles 17 higher up the tub wall, the pump 11 is arranged with its axis vertical and with its inlet conduit 13 below a removable grating 14 in the bottom of the tub, the conduit 13 being straight and short, and giving direct access, on removal of the grating 14, to the rotor of the pump for cleaning purposes. An electric heater 16 is mounted below the grating 14. The outlet pipe 24 from the pump 11 is forked at 25, one branch 19 leading to the nozzles 17 while the other 26 discharges at 27 into a sink 28. The flow of water through the pipes 19, 26 is controlled by cams 29, 30 respectively, keyed to a common shaft 31 actuated by means of a lever 32. With the lever in the washing position shown at 32 in Fig. 2 the cam 30 crushes and closes the tube 26 while the cam 29 leaves the tube 19 entirely free. At position 32<1> both tubes are completely closed, while on moving to position 32<11> the supply to the nozzles remains cut off and all the water is evacuated through the pipe 26. In position 32<111> both tubes 19 and 26 are open, some of the water being discharged at 27 and some being circulated through the nozzles. This position can be used for rinsing, fresh water being added by means of a hose 23 connected to the supply. A supplementary washing action can be produced by placing the discharge end of the pipe 26 in the position shown at 27<1>, so as to produce a jet striking the surface of the water, the lever 32 being between positions 32 and 32<111>. Overfilling of the tub during rinsing can be prevented by means of an overflow duct Fig. 3 (not shown) connected to the low pressure chamber of an ejector inserted in the evacuating pipe 26.
