Patent GB-713522-A (GB)
Title: Improvements in or relating to the preparation of dihalo-difluoro-methanes
IPC: C07C17/10
Filed: 1950-12-29
Abstract: A brominated product containing a substantial amount of dibromodifluoromethane and/or bromochlorodifluoro methane is obtained by reacting bromine and chlorodifluoromethane at 300-1000 DEG  C. in such proportions that for each mol. of chlorodifluoromethane there is provided 0.8 to 1.2 mol. of bromine.  When the reaction is carried out at between 550 DEG  and 750 DEG  C. a mixture of perhalomethanes containing a substantial amount of chlorobromodifluoromethane and of dibromodifluoromethane is obtained.  Bromochlorodifluoromethane is the primary product when the reaction is conducted at 300 DEG  to 650 DEG  C., preferably 550-650 DEG  C., whilst at 650-900 DEG  C., preferably 650-750 DEG  C., the primary product is dibromodifluoromethane.  The invention also comprises as a new product bromochlorodifluoromethane having a density (d DEG 4) of substantially 1.917 and a boiling point of substantially -2.5 DEG  C. In carrying out the process the chlorodifluoromethane may be passed into a vaporizer containing bromine maintained at about 42 DEG  C. and the mixed vapours then passed into a combustion tube maintained at the required temperature, the exhaust gases from the tube being introduced into the bottom of a scrubber wherein they are scrubbed with water or alkali to remove unreacted bromine and hydrogen bromide.  The scrubbed gases are then dried and fed through a series of traps cooled to below -20 DEG  C. and the condensate fractionated to recover the perhalomethanes produced. The results obtained by operating the furnace at 650 DEG , 725 DEG , 750 DEG  and 775 DEG  C. are tabulated.  Under preferred operating conditions the combined weight of the perhalomethanes is at least 50 per cent of the brominated product.  The reaction is usually effected at atmospheric pressure but higher or lower pressures may be used. The chlorobromodifluoro methane produced may be reacted with certain olefins to produce new adducts and any mixture of the perhalomethanes obtained by the process may be used as a fire-fiighting liquid (see Group XXI).

Abstract: 877,875. Packaging-machines. HILLMAN, J. G. E., and MOLINS ;MACHINE CO. Ltd. Oct. 18, 1957 [Oct. 18, 1956], No. 31706/56. Class 94(1). Apparatus for filling collecting receptacles with cigarettes from a cigarette making machine &c. comprises a collecting station from which cigarettes pass downwards to the receptacles, means being provided to halt the flow from and support the cigarettes in the collecting station when a desired quantity has been fed to the receptacles. In one embodiment, two streams of cigarettes flow from belts 1 to feed wheels 3 from which they fall into the collecting station 2. Rods 6 on a horizontally reciprocating bar 5 agitate and align the cigarettes which are supported on a platform 15. The platform 15 moves progressively downwards to lower the accumulating cigarettes into an open fronted receptacle T. Before the platform reaches its lowermost position, needles 12 on bars supported by spring arms 13 advance inwards to the position of Fig. 2, so that their points engage opposite ends of a row of cigarettes to arrest their downward movement. As a gap appears below this row a plate 12a is passed horizontally into the collecting station to provide additional support. When the platform reaches its bottom position, it withdraws sideways, leaving the cigarette stack in the receptacle, which is moved along to present a second compartment thereof for filling, or permit a fresh receptacle to take its place. The platform 15 then rises and advances beneath the plate 12a which latter, with the needles 12, is withdrawn to permit recommencement of filling. In other embodiments, a row of needles on one side only of the collecting station may be fitted. The receptacles may form part of the filling apparatus, being open on opposite sides so that a horizontally reciprocating pusher plate can transfer the stack of cigarettes to a container arranged alongside Figs. 7-17, (not shown). Photo-electric means may scan the level of the cigarettes in the collector 2 whereby if the level falls below a predetermined line, the now of cigarettes to the receptacle is checked until the level is made up by incoming cigarettes. The platform 15 may have a wedge-shaped portion on its upper surface to compensate for differing diameters at opposite ends of cigarettes with cork tips Fig. 4, (not shown). In the Provisional Specification, it is stated' that the needles may be replaced by rollers 23, Fig. 6, which, when not rotating, prevent passage of cigarettes. Specifications 820,845 and 877,876 are referred to.
