Patent GB-656457-A (GB)
Title: Improvements in or relating to the production of benzene hexachloride
IPC: C07C23/12
Filed: 1947-06-18
Abstract: Benzene hexachloride enriched in g -isomer is prepared by chlorinating benzene mixed with an inert solvent with actinic irradiation, stopping the chlorination when the volume of benzene converted is 10-60 per cent, preferably 25-50 per cent, of the total volume of liquid present, removing the separated solid, and recovering the g -enriched product from the solution without further chlorination.  It is preferred to correlate the temperature of separation with the extent of chlorination, i.e. when the latter is 50 per cent or less the separation temperature is not higher than 40 DEG  C., when it is more than 50 per cent the p  separation temperature is 40-80 DEG  C., and when it is 40 per cent or less the temperature used is about 25 DEG  C.  The chlorination temperature is preferably below 50 DEG  C., agitation is used, and unreacted chlorine is removed from the solution, e.g. by air-blowing, after the chlorination.  The inert solvent may be acetic acid, carbon tetrachloride or chloroform, and is preferably used with a minor proportion of benzene, which is then completely chlorinated.  The g -enriched product may be chilled at 0-5 DEG  C. to crystallize it in part.  An example is given in which acetic acid is used as the solvent.  The Specification as open to inspection under Sect. 91 comprises the statement that benzene may be used alone in the chlorination. This subject-matter does not appear in the Specification as accepted.ALSO:A benzene hexachloride rich in the g -isomer, e.g. 90 per cent is used as an insecticide, e.g. when mixed with a carrier such as pyrophyllite or clay, or dissolved in xylene, toluene, acetone or methylnaphthalene for spraying purposes, or emulsified in xylene solution with water using for example an alkylphenoxy polyethoxy ethanol.

[Also in Groups XXI, XXII and XXX] A turntable, e.g. for foundry use in making moulds, or for locomotives, missile launching platforms, artillery, &c., comprises a table member 20, Fig. 5, rotatably supported by wheels 26 on a fixed base 30, and indexing means for imparting to the table member successive equiangular displacements. The indexing means includes radial guides 34, Fig. 1, on one member, e.g. the base, and a drive-arm 50 pivoted to the other, e.g. the table, for horizontal oscillation about a vertical axis spaced from the table axis, between extreme positions in which the distal end of the arm is in vertical register with inner end regions of adjacent guides. The arm is oscillated by a reversible motor 54, e.g. electric or hydraulic, and a pin 52, Fig. 11, is vertically movable at the distal end of the arm to move a roller 53 into and out of a guide. The pin is moved by pins 164, 166 on arms 170 actuated, e.g., by a piston-andcylinder motor 184. Each operation necessary for a single indexing movement is motivated by a preceding operation. Where hydraulic power is used, an indexing movement is initiated by manually depressing a lever 220, Fig. 12, causing valve E to supply pressure liquid via pipe 214 to raise piston 138 and remove a locking roller 60 from its detent 62 on the base. Piston 138 actuates via abutment 252 plunger d of a valve D to rotate motor 54 clockwise thus rotating the table anti-clockwise through 90 degrees. At the end of its stroke, arm 50 actuates the plunger b of a valve B causing piston 138 to engage roller 60 with another detent 62 and piston 184 to raise pin 52. Piston 184 actuates via abutment 250 the plunger c of a valve C which causes motor 54 to rotate anti-clockwise to the other end of its stroke where arm 50 actuates the plunger a of a valve A which lowers piston 184 and pin 52 to engage the next guide with roller 53. The next indexing movement is initiated by depressing lever 220. The indexing may be controlled and actuated pneumatically or electrically.

Abstract: 966,789. Vehicle headlamps. P. CIBIE. April 30, 1962 [May 4, 1961; May 8, 1961], No. 16509/62. Heading F4R. A headlamp for producing a main and a dipped beam has a single light source with a filament extending along the axis of a reflector, retractable means for partly masking the radiation from the source and correcting means for adjusting the effective position of the source with respect to the focus of the reflector to provide correct lighting when either beam is used. In the form shown the reflector 1, Fig. 1 consists of a paraboloid of rotation top and bottom by flat horizontal sections 2, 3. A tubular lamp bulb 4 with the filament arranged along the axes of the paraboloid close to the focal point is carried by a support 5. Flaps 6a, 6b carried by spindles 7a, 7b parallel to the optical axis are arranged adjacent the filament and can be moved from the position shown, in which they do not affect the light beam from the lamp into a position in which they are extended to mask the upper half of the reflector. The spindles carry masking pinions 8a, 8b and the spindle 7a carries a magnet 9 arranged between the polepieces 10 of an electromagnet 11, energization of which causes the flaps to be extended against the action of a return spring 12. A nut 14 on the support 5 engages a screw thread 13 on the spindle 7a so that the bulb is moved away from the focus of the reflector when the flaps are opened. In a modification, the flaps 29, 29a, Fig. 8, are mounted on coaxial spindles each of which carries a magnet 36 and 37 (not shown) and both of which are acted upon by one or other of a pair of polepieces 40, 41, connected to the cores of associated coils 42, 43, energization of one coil opening and of the other closing the flaps. A single coil having a polarity reversing relay or a single coil acting in opposition to a return spring may be used. Alternatively, the bulb may be stationary and the reflector consist of two half-paraboloids connected by a horizontal plane, the bulb being situated at the focus of the lower half-paraboloid and away from the focus of the upper half-paraboloid which produces the dipped beam. Instead of modifying the reflector, the front lens of the lamp may consist of a lower half through which the dipped beam passes and which may be fluted and an upper half in the form of a stepped lens.
