Compounds of the above general formul  are phosphorus pentachloride, phosphorus oxychloride, sulphuryl chloride, chlorosulphonic acid and the analogous bromine compounds.  The intermediate 5,7,8-substituted alkyl, aryl, or aralkyl tocols are converted to the corresponding 5,7 and/or 8-alkyl, aryl or aralkyl tocols by hydrolysis and reduction, or by reduction alone, e.g. the Clemmensen reduction or catalytic hydrogenation.  For the production of a -tocopherol, paraformaldehyde or dry formaldehyde gas may be employed.  Examples use as starting materials 7,8-dimethyltocol, 5,7-dimethyltocol, rice oil concentrate, and soybean oil concentrate; the halogenating agents indicated above are also used.

Patent GB-321581-A (GB)
Abstract: 321,581. De Havilland Aircraft Co., Ltd., and Brant, A. J. Dec. 6, 1928. Time of working of machines.-An apparatus for use on aircraft for registering the flying time comprises a mechanism of the stop watch type and an air pressure operated element for controlling the time registering mechanism. In the form shown in Fig. 1 a stop watch movement is mounted in a casing 10 on a base plate 11 the hour hand 13 being geared to make one revolution in 120 hours while the minute hand 14 rotates at the standard rate. A vane 17 pivotally mounted at 18 is normally pressed by a spring 19 against a stop 20 and is arranged so that when the aircraft is in flight the air pressure on the vane 17 overcomes the spring action when the relative air speed exceeds a predetermined minimum and by means of a button 21 on the vane depresses the stop arm 16 of the watch to start the movement. Instead of a vane a disc or cup may be operatively connected to the stop arm or the stop arm may be controlled by a governor device actuated by a windmill. The spring-driven watch movement may be replaced by power from a windmill provided with a constant-speed device to actuate the usual escapement. To indicate when overhaul or maintenance work falls due one or more indicating pointers such as 24, 25 set by means of rotatable rings 22, 23 are provided. These pointers may be, provided with projections (not shown) to arrest the movement of the hands 13, 14 to draw attention to the fact that the total flying time has been reached. The air pressure may be obtained from the Pitot-tubes used in connection with the air speed indicator. To register the engine running time. the air pressure element can be arranged in the slip stream of the propeller.
