Title: Improvements in or relating to the modification of rice
Inventor: WILLOCK JAMES TAYLOR
IPC: A23L7/196
Filed: 1960-11-30
Abstract: In producing modified rice grains which are particularly suitable for rice puddings, the moisture content of milled rice grains is raised, uniformly throughout them at a temeprature below the gelatinizing point of the starch therein, to a value between 18 and 30%, preferably between 22 and 28%, by weight, and the moist grains are then heated to expel moisture rapidly, e.g. to reduce their moisture content to between 10 and 14%, and thus create fissures in the grains and increase their porosity.  The milled rice grains may be treated with humid air until they absorb sufficient moisture.  Alternatively, the milled rice grains may be soaked in, or sprayed with, water for 30 minutes at 20 DEG C. or for 10 minutes at 55 to 60 DEG C., then centrifuged to remove surface moisture and conditioned, as by being contained in a closed space for 30 minutes to 4 hours at 20 DEG C., or retained, for 10 minutes at 55 DEG  C., in a current of air having a relative humidity between 80 and 90%.  The moist grains may be heated by infra-red or dielectric, e.g. radio-frequency, heating. Alternatively, the moist grains may be heated by passing air or inert gas, having a temperature between 90 DEG  and 120 DEG C., over and/or through them for 2 to 6 minutes, as by carrying a thin (0.75 inch) layer of moist grains on a travelling, permeable, e.g. perforated, belt through a dryer and blowing heated air or inert gas upwardly through the grains on one portion of the belt and then downwardly through the grains on another portion of the belt.  The dried grains may then be cooled, as by passing air at room temperature downwardly through them as they are carried on the belt.

Title: Shutoff valve
IPC: F16K1/42
Filed: 1976-10-04
Abstract: A sealing system for a shutoff unit comprising two substantially ring-shaped sealing elements, one of which is tightly connected with the housing or with the blocking element of the shutoff unit and the other is either tightly connected with the blocking element or the housing or is formed thereat. The sealing elements are pressed against one another due to a closing movement of the blocking element for carrying out a shutoff action. The one sealing element is constructed as a thin-wall body of undulated or wave-shaped cross-section and elastically deformable under the action of the closing force, said elastically deformable thin-wall body extending over the ring width of the corresponding sealing element and in the closed position, with deformation of its wall, bearing by means of wave peaks protruding from one side of the thin-wall body against the other sealing element at least at two ring regions with line contact. The blocking element or housing which is connected with the thin-wall body possesses beneath these ring regions free deformation spaces for its wall and adjacent such spaces a respective support extending parallel to the ring region for each wave peak protruding from the other side of the thin-wall body. The marginal regions of the ring-shaped thin-wall body of undulated cross-section are prevented from moving in a manner which would increase the ring width.

Abstract: 1,079,528. Photo-electric flame detector. ELECTRONICS CORPORATION OF AMERICA. Oct.21, 1964 [Nov. 5, 1963], No.42907/64. Heading G1A. In a fail-safe detector flame failure is periodically simulated by a chopper 14 in the flame radiation beam, the resulting appearance and disappearance of the flame causing a capacitor 90 to be repeatedly charged and discharged but maintained at a potential high enough to hold a control relay 96 actuated, which is released only when a complete failure of the flame prevents the capacitor 90 from recharging. Signals from the lead sulphide detector 12 after passing through a filter amplifier tuned to the flicker frequency of the flame, charge capacitor 52 to cause triode stage 62 to conduct, which by charging capacitor 74 shuts off triode stage 64. The voltage across the anode resistor 78 is now removed and allows capacitor 84 to recharge the relay capacitor 90. Upon removal of the flame radiation by the chopper, triode stage 62 ceases to conduct and triode stage 64 conducts; the voltage across anode resistor 78 is restored so isolating relay capacitor 90 by diode 88 and recharging capacitor 84. If complete flame failure occurs triode 64 is held conducting so the charge on the relay capacitor 90 is not regularly replenished and the relay contacts 90 open to operate a fuel valve 98. Any component failure has a similar effect. In another embodiment not using the flame flicker frequency Fig. 2 (not shown) an avalanche type of detector is fed from an A.C. supply. The pulses are produced as the detector repeatedly breaks down when irradiated are fed through a frequency selective network to operate an S.C.R. to maintain a transistor in a non-conducting condition. A capacitor similar in function to 84 is charged and discharged as the transistor conducts and is shut off in correspondence with the absence simulator.
