Title: Process for preventing the autoxidation of edible fats and oils, and of foods containing fats or oils
IPC: A23L3/358
Filed: 1948-12-10
Abstract: The autoxidation of edible fats and oils is prevented by incorporating therewith a small proportion, e.g. 0.005 to 0.01 per cent, of a tetra-alkyl thiuram disulphide.

Title: Improvements in or relating to radar display apparatus
Inventor: EASY MAURICE HENRY
IPC: G01S7/24
Filed: 1958-11-06
Abstract: 866,685. Radar. DECCA RECORD CO. Ltd. Feb. 2, 1960 [Nov. 6, 1958], No. 32181/58. Class 40(7) Relates to a craft borne radar with a position stabilized C.R.T. P.P.I. 10 having an adjustable range scale selected by a switch 32 in which the display is displaced in accordance with movement of the craft by shift voltages applied to auxiliary X and Y shift coils 60, 61 from corresponding potentiometers 38 which are driven respectively by the sine and cosine outputs from a mechanical resolver 24 whose input shaft 19 is rotated by a motor 18 in accordance with the distance travelled by the craft, the angular setting of the resolver being determined by a shaft 27 controlled in accordance with the heading of the craft by means of a compass 29 or a manual control 28; as shown the distance motor 18 is controlled by a ships log 17 or by a pulse generator 21 whose frequency is set manually in accordance with the speed of the craft. According to the present invention the drive ratio between each output shaft 25, 26 of the resolver 24 and its corresponding potentiometer 38 is controlled by the radar range-scale switch 32 so that the scale of the X and Y position shifts is equal to that of the display. The selectable drive ratios may be effected by mechanical gears but as described each resolver output shaft, e.g. 25, is coupled to a transmitter 30 producing four output pulse trains. Each pulse in any one train is produced in response to a predetermined change in the angular position of the shaft 25 and the predetermined changes for the four pulse trains are different and are in the same ratio as the four different display scales selectable by the switch 32. The pulse trains from the transmitters 30, 31 corresponding to the scale selected by the switch 32 are selected by switches 34, 35 ganged to the range switch 32 and the outputs from the switches 34, 35 are applied to stepping motors 39 driving the shift potentiometers 38. The pulse train outputs from the transmitters 30, 31 may be applied to a number of different display units which may be operated on the same or different range scales as required. As shown the resolver 24 and transmitters 30, 31 may be in a track unit 15 remotely situated from the display and other similar track units, e.g. unit 16, may be provided, the outputs from the different track units being selected or combined by ganged switches 40. In general combination may be effected by combining the transmitted information electrically or mechanically before it is used to drive the shift potentiometer 28 or by combining the outputs from the potentiometers 28. Such combination may be employed for combining different motions, e.g. the speeds and directions of own ship and of a tide or current to give a ground stabilized display or the motions of own ship and of a moving object to stabilize the display with respect to the object or a combination of three such motions. Specification 795,288 is referred to.

Abstract: 300,177. I. G. Farbenindustrie Akt.- Ges. Nov. 7, 1927, [Convention date]. Urethanes of secondary alcohols which contain an aryl or substituted aryl group in the #-position to the hydroxyl group are prepared from the alcohol in the usual manner, e.g. by treatment with carbamic acid chloride or by conversion into the chlorcarbonate by means of phosgene and subsequent treatment with ammonia. The products possess antipyretic properties. Examples are given of the preparation of the urethanes of phenylethyl - methylcarbinol, phenylethyl-ethylcarbinol, and (alpha-allyl-#-phenyl) ethyl - methylcarbinol.
