Title: Production of methyl chloroform
IPC: C07C17/087
Filed: 1961-11-20
Abstract: Methyl chloroform is produced in a continuous process by introducing elemental chlorine and a vapour stream containing 1,1-dichloroethane into a chlorination zone at elevated temperature, removing the methyl chloroform and hydrogen chloride gaseous product and passing it to a hydrochlorination zone at elevated temperature, containing a Friedel-Crafts catalyst, also feeding vinyl chloride into this zone thereby forming a methyl chloroform and 1,1-dichloroethane liquid mixture, separating, and returning at least a portion of the 1,1-dichloroethane to the chlorination zone.  The chlorine may be introduced into the chlorination zone at 500 DEG F. to 600 DEG F. and the 1,1-dichloroethane at 225 DEG F. to 300 DEG F.  The chlorination zone may be in two portions, the first is a recycle chlorinator (see Specification 883,256) operated at between 420 DEG F. and 700 DEG F. and the second, a soaker portion operated at between 700 DEG F. and 900 DEG F.  The second portion is preferably at least 50 DEG F. higher than the first portion.  The gaseous product from the chlorination zone, and vinyl chloride may be introduced into the hydrochlorination zone at below 200 DEG F. The Friedel-Crafts catalyst, e.g. ferric chloride, may be introduced in a downwardly falling liquid stream at 50 DEG F. to 120 DEG F.  The 1,1-dichloroethane/methyl chloroform liquid mixture produced may then be led to a second chlorination zone.  The methyl chloroform is recovered by the method described in Specification 930,172.  The molar ratio of chlorine to 1,1-dichloroethane is 0,3 : 1 to 0,9 : 1. The vapour stream containing 1,1-dichloroethane may also have between 2 and 20% by weight of other chlorinated hydrocarbons.  The molar ratio of vinyl chloride to hydrogen chloride fed to the hydrochlorination zone is 0,9:1 to 1,1:1, the hydrochlorination zone being operated at 3 p.s.i.g.

Abstract: 1,272,005. Image intensifier tubes. MULLARD Ltd. 3 July, 1970 [21 Aug., 1969], No. 41704/69. Heading H1D. In an image intensifier tube comprising a photo-cathode and a luminescent output screen, the latter is adapted to emit light of different colours in response to electrons of different energies. The tube may be a diode (Fig. 1, not shown) comprising a spherical photocathode and a frusto-conical anode connected to a plane or curved output screen; a voltage source switchable between two or three values according to the number of colours is connected between anode and cathode. In Fig. 2 there are two cylindrical electrodes Af and Ac between the cathode P and screen SO, and in this case the ratios of the potentials on the electrodes must be kept constant, for example by the potentiometer R1, R2 across which different voltage sources Bd may be connected by switch SWd. If the tube is to be used for X-rays a fluorescent screen is arranged adjacent the cathode, and may be separated from it by a fibre optics plate. In another arrangement, Fig. 3 (not shown), a channel multiplier is provided between the cathode and the screen, a switchable voltage source being connected between the screen and the output electrode of the multiplier. When used for X-rays there may be an input fluorescent screen or alternatively the channel plate may be X-ray absorbent, in which case no photo-cathode is necessary.

For simplicity Fig. 1 shows the level L 1 auxiliary store 18a associated with the L1 store 14a and processors 10a of sub-system A, but in practice store 18a and an associated journal 20a, which records the order in which changes are made to the data in store 14a, would be packaged with sub-system B and store 18b and journal 20b would be packaged with sub-system A. Similarly the copy back BSM 34 for sub-system B at levels L2, L3 is packaged with the data storage BSM's for sub-system A and vice versa. At level L4 which comprises a plurality of disc units 38 each having a plurality of actuators for accessing dedicated groups of cylinders, the copy back area of each sub-system is on a different spindle 38 to that on which its data is stored. The lowest level L5 of storage is formed by a magnetic tape cartridge unit 40. Two stations are provided on each of units 38, 40 for connecting them in two independently powered loops 42, 44. Associated with level L4 in each subsystem is a pair of buffers, each buffer having a capacity equal to that of one disc unit track, copy back of a complete track being initiated when a buffer is filled, and further copy back data being loaded into the other buffer of the pair while copy back on to the disc unit is taking place. With each new modification of a page a new copy back space on disc is allocated and a bit map associated with L4 is updated to invalidate any existing previous modification in L4 so that it will not be copied back to L5. Each directory and store has SEC-DED facilities to initiate the appropriate non-connectible error recovery according to whether the error occurred in a data store, directory or journal and whether or not any change has been made to the data since it was paged up from the next lower level. The disclosure is identical with that of Specification 1,533,767.
