Title: Improvements in or relating to the steam treatment of cereal grains
IPC: B02B1/00
Filed: 1945-09-25
Abstract: To produce cereal grains from which the natural flavour and aroma are partly or wholly removed and in which the endosperm is continuous and translucent and is enriched with vitamins from the germ and other parts of the grain, the grain, e.g. wheat, rice, barley, oats, is subjected in a closed vessel to the action of saturated steam at low pressure until the temperature of volalitization of the flavour and aroma producing substances is reached, and the pressure then suddenly released, these operations being repeated until the volatile substances are removed to the desired extent, and thereupon the grain is dried.  Before drying, or after partial drying to increase absorbency, the grain may be impregnated or sprayed with a desired flavouring, which may be a condensate from the vapour obtained by carrying out the steaming process on another kind of grain.  Examples are concerned with raising the temperature to 100 DEG -150 DEG  C. in half a minute of eight tons of wheat and eight tons of barley respectively in a rotary vessel of 804 cubic feet capacity by means of saturated steam at 10 pounds a square inch gauge pressure, carrying out, for wheat, four steamings for two and a half minutes, each followed by a blow-off through a 20 inch diameter orifice, and, for barley, three steamings for three and a half, three and four minutes, each followed by a blowoff through a 20 inch diameter orifice, and after the last blow-off in each case applying a vacuum to exhaust the volatized substances and initiate drying of the grain.

IPC: G01C17/38
Filed: 1953-09-09
Abstract: 775,440. Electric indicating systems. MINISTER OF SUPPLY. Aug. 24, 1954 [Sept. 9, 1953], No. 25020/53. Class 40 (1). A magnetic compass system for use on structures of magnetic material, such as a steel vehicle, a ship, or an aircraft, comprises two transmitting compass or magnetometer units arranged one at each of two points where the deviations induced by the magnetization of the structure bear a constant relation for all headings and other attitudes of the structure, the units being such as to produce outputs of a form related to the magnetic heading of the structure, an automatic device to which the outputs of the two compass units are fed and which provides a mechanical output for operating a directional indicator and an electrical output consisting of an error voltage from the unit at the point of lesser deviation corrected by the subtraction from the voltage of a suitable proportion of the error voltage from the unit at the point of greater deviation, the electrical output thereby being an error voltage which is reduced in strength compared with that of either unit separately but corrected for deviation, and means for varying the mechanical output of the automatic device, to which means the corrected error voltage is fed. In Fig. 2 the compass units 10, 11 are provided with exciter coils 12, 16 fed with 400 c/s. A.C. and their outputs are fed to the stators of two selsyns 20, 21. The rotors of these two selsyns are locked so as to turn together and the common shaft is provided with a pointer 23 associated with a compass scale; the selsyns are so arranged that in the absence of any deviation their two rotors will each generate zero volts when the locked rotor system gives the undeviated reading of the detector units. The output of one rotor plus a proportion of the output of the other rotor, the proportion being equal to the ratio of the deviations of the compass units, are fed through an amplifier 25 to a servo motor 26 which rotates the rotor shaft 22 until the pointer 23 indicates the direction of the undeviated field of the earth. In Fig. 2 the proportion of the output of one rotor which is used is controlled by a potentiometer; in a modification, Fig. 3 (not shown), a transformer is used instead.
