Abstract: 755,750. Quick-cooking rice. GENERAL FOODS CORPORATION. Feb. 25, 1954 [July 29, 1953], No. 5571/54. Class 58. Rice is gun-puffed to yield quick-cooking rice having a volume 2 to 3 times its original volume. The puffing gun may have a cylindrical barrel closed at one end and fitted at the other end with a hinged door releasably locked by trigger mechanism. The rice may be soaked in water and heated in the gun barrel, by a gas flame and/or live saturated steam under pressure, until it attains a terminal temperature between 325‹ and 370‹ F. and a terminal moisture content ranging from a value between 18 to 38 per cent at 325‹ F. to 28 per cent at 370‹ F., as defined by areas C 1  and C 2  on the graph, and thus subjected to a water vapour pressure corresponding to that of saturated steam at the particular rice temperature concerned, this pressure being suddenly released to the atmosphere by triggering-off the gun. The rice may be subjected to the terminal conditions prevailing in area D of the graph and after puffing, any puffed rice produced with a volume greater than that of the quickcooking rice of the invention, may be removed. The rice may be puffed by using apparatus described in Specification 700,140. The pressure in the gun may be boosted by the introduction of air or carbon dioxide or an inert gas such as nitrogen.

Title: Improvements in or relating to electric pulse generators
IPC: H03B19/10
Filed: 1948-02-28
Abstract: 641,512. Pulse generating circuits. SPERRY CORPORATION. Feb. 28, 1948, No. 6242. Convention date, Aug. 19, 1943. [Class 40 (vi)] A pulse generator comprises a polyphase A.C. source, each phase feeding a pulse producer, the outputs of the several pulse producers being combined to deliver pulses at double the frequency of the A.C. source multiplied by the number of phases. Sine waves from the two-phase alternator 11, Fig. 1, are squared in valves 12, 13 the grids of which are given a positive bias. The output of each valve is differentiated over capacitor-resistor combinations 43, 44, 45 and 46, 47, 52 to give short pulses at the grids of valves 32, 33. Valve 33 operates with zero bias and anode load comprising resistors 48, 49, the negative going pulses being inverted while the positive pulses are ineffective due to grid current. Valve 32 is biassed beyond cut-off so that only the positive-going pulses are effective to cause the valve to pass current and operate as a cathode follower, valve 33 acting as a load impedance. A train of positive-going pulses having a frequency four times that of the alternator 11 is produced. In a modification, Fig. 5, the sine waves are distorted over peaking transformers 63, 64 and fed in push-pull to valves 61, 62 having a common anode load 67 to produce a pulse train 89 of the desired frequency. The pulses are differentiated and applied to the left-side of valve 87 which is biassed beyond cut-off. The pulses at the anode are fed to the right side of valve 87 operating at zero bias to give the positive pulse train 93.
