IPC: H01J31/64
Filed: 1960-10-24
Granted: 1961-12-01
Abstract: 957,026. Cathode-ray storage tubes. RAYTHEON CO. Oct. 4, 1960 [Oct. 28, 1959], No. 34053/60. Heading H1D. [Also in Division H4] In a signal storage tube consisting of writing gun 3, storage electrode 4, secondary electron collector 5 and reading gun 2 in which the reading beam passes through the storage electrode to impinge on the collector 5 which also serves at the output electrode, the potential difference between electrodes 4 and 5 may be adjusted to effect complete or partial erasure of the charge pattern on the storage electrode. It is stated that the potential difference between electrodes 4 and 5 governs the number of elastically scattered primary electrons emitted from the collector electrode 5, these electrons having sufficient energy to reach the storage electrode 4 where they neutralize the charges of the charge pattern. Electrodes 6 and 7 are accelerating electrodes for the respective writing and reading beams. The tube may be used to convert a television picture received at one scan rate, e.g. 60 c/s., into an equivalent picture at another scan rate, e.g. 59.9 c/s., which may be, for example, in synchronism with a local power frequency. The tube may also be used in a radar system having a P.P.I. cathode-ray tube display in which it is desired to display target history to any convenient extent.

Title: Improvements in or relating to the deodorization and other purification of fish oils
IPC: C11B3/14
Filed: 1920-01-13
Abstract: Odourless, tasteless, and fluid oils are obtained from fish oils by cautious hydrogenation so that only the highlyunsaturated acids are affected, then by slight polymerization by heating for several hours and allowing to cool in an atmosphere of hydrogen, and finally by treatment with steam to effect complete deodorization.  In an example, 100 kilos. whale oil purified by caustic soda or sulphuric acid in the usual way is hydrogenated at 150-200 DEG  C. in an autoclave with the aid of a nickel catalyst whereby the iodine number is reduced from 125 to 100, filtered, and slightly polymerized to remove the last traces of highly unsaturated acids by heating to 260 DEG -280 DEG  C. in a closed vessel for 3-4 hours while a current of hydrogen is passed through.  The oil is then allowed to cool in an atmosphere of hydrogen to 80 DEG -100 DEG  C., and finally treated in vacuo with a current of superheated steam, the temperature of which is about 250 DEG -300 DEG  C.

Title: Valve to control the feed of liquids
IPC: F16K17/20
Filed: 1971-01-12
Abstract: 1342305 Priming pumps S CAPPELLI 12 Jan 1971 [15 Jan 1970] 1509/71 Heading F1C [Also in Division F2] A safety valve to control the feed of liquid from a tank to a pump comprises three chambers 18, 17 and 22, the lower chamber 18 having an inlet 2 in communication with liquid in a tank (501) Fig.1 (not shown) and an outlet 3 in communication with the suction side of a pump (509A or 509B); the intermediate chamber 17 having an inlet 4 receiving the return liquid from the pump; and the upper chamber 22 being permanently in communication with the lower chamber 18 via bores 21, 20 in a shaft 14. The shaft 14 is secured to an upper diaphragm 15 and passes through an aperture in a lower diaphragm 12. Secured to the lower diaphragm is a sleeve 10 which can move axially on the shaft 14 to open and close a passageway 23 which connects the intermediate chamber with the lower chamber 18. The upper diaphragm 15 can move to open and close a passage 6 (Fig.4) which communicates with the tank via passage 6A. Operation. In normal operation, the pump draws liquid from the tank via the inlet 2 and outlet 3 and returns liquid to the inlet 4 some of which recycles through the passageway 23, the rest passing back to the tank via passage 6 through a throttle 5. To prime the pump a handle 9 is moved to lessen the degree of throttling and, by a projection (5E) Fig.6 (not shown) raise the sleeve 10 and shaft 14 which closes the passageway 23 and opens the passage 6 to chamber 17 thus causing a large depression at the lower chamber 18. The flow of liquid may be stopped by rotating the handle 9 until a projection 5C urges the shaft 14 downwards to close the valve member 19. Should a leak occur at the intake of the pump depression in chamber 22 decreases and the spring 25 urges the shaft 14 downwards to close the valve member 19. Should a leak occur in the return from the pump, the depression caused in chamber 17 allows air to inflow from the leak or passage 6 which passes to chamber 18 and so allows the shaft 14 to drop. Instead of being housed in the intermediate chamber 17, the member 5 may be housed in the lower chamber (18) Fig.12 (not shown). Also, only one membrane need be used Fig. 13 (not shown) or only two body portions of the valve Figs.14-19 (not shown).

Abstract: 914,806. Flowmeters. MINNEAPOLISHONEYWELL REGULATOR CO. Jan. 15, 1959 [Jan. 15, 1958], No. 1537/59. Class 40 (1). [Also in Group XXXVI] In a system in which the amount of a fluid material, e.g. an aircraft fuel remaining in a container 10 is continuously shown by an instrument 55 responsive to a voltage derived from a potential divider 38, the normal adjustment of the potential divider in accordance with the level of the material in the container is discontinued while the craft is accelerating or in an abnormal attitude and the voltage registered by the potentiometer setting is continuously supplemented or decreased during this period in accordance with the rate at which the material is entering or leaving the container. Fig. 1 shows one embodiment in which a capacitive level sensing element 12 and density sensing element 20 are connected to a fuel gauging system 15 whose output controls, via a servo system, the position of the slider of potentiometer 38, the potential at this point is applied to a second serve system to position the indicator 55 to indicate the mass of fuel in the tank. Inclination or acceleration of the container operates, via pendulous weight 150, relay 163 to change over switch contacts 92, 94 and 96, from the position shown. Switch 92 holds motor 30 in its existing position while contacts 94 modify the voltage appearing on slider 36 of potentiometer 38 by a potential appearing on the slider of potentiometer 115 which is positioned by motor 125 of an integrator circuit in correspondence with the integrated mass rate of flow. The integrator circuit is fed via switch 96 with the potential from the slider of a potentiometer 83 which is positioned via a servo system by the output of the mass rate flowmeter 71. When the container resumes its normal position, or speed, switches 92, 94, and 96 resume the position shown and indicator 55 is positioned once again only in accordance with the position of slider of potentiometer 38. In addition the slider of potentiometer 115 is driven to its central or zero output position by connecting the slider via switch 96 to energize motor 125. In an alternative system, Fig. 2, a volumetric flowmeter is used in place of the mass flowmeter of Fig. 1 and the output of this flowmeter is modified by the output of the density sensor 20 before the flowmeter output is fed to the integrating circuit; otherwise the system is identical with that of Fig. 1.
