Title: Process for reducing and stabilizing the leakage currents in electrolytic capacitors
IPC: H01G9/00
Filed: 1966-06-29
Abstract: 1,086,350. Electrolytic capacitors. CIBA Ltd. June 29, 1966 [July 22, 1965], No. 29254/66. Heading H1M. Leakage currents in electrolytic capacitors, having either a solid or liquid electrolyte, are reduced and stabilized by impregnating the anodic oxide layer with the alkoxide of an element which will form a non-conductive non- volatile oxide by decomposition of the alkoxide. The alkoxides are preferably formed from alcohols having 1 to 10 carbon atoms, e.g. methanol, ethanol and iso-propanol. The element may be silicon, calcium, barium, magnesium, yttrium or cerium, but preferably a valve metal, e.g. tantalum, niobium, zirconium, titanium or aluminium. Mixtures of alkoxides may be used. The anode is dipped in an e.g. methanolic solution of the alkoxide, dried and the alkoxide is decomposed by heating, optionally after hydrolysis with e.g. ammonia or steam. The oxide layer may be produced prior to forming, or an additional forming treatment may be carried out after the oxide layer has been applied.

Title: Improvements in or relating to valves for oil burner pumps
IPC: F23K5/14
Filed: 1964-07-17
Abstract: 1,063,905. Valves. O. ECKERLE. July 17, 1964, No. 29272/64. Heading F2V. In a valve for use in the supply from an oil burner pump to the burner nozzle supply line, a piston 10 is displaceable within a stationary sleeve 7, located by a spring 8 and forming a conically tapering chamber 29 within bore 1, and is loaded into contact with the face 9 of a burner nozzle connection screw 5 by a spring 11, adjustable by axially displaceable non-rotatable round or hexagonal nut 13 upon screw 12. On operation of the oil pump, oil passes from bore 30 into chamber 29 and air is initially vented via port 28, annular gap 32, throttle bore 15 and return passage 16 and return channel 35 until increasing pressure, acting on bevel 31, displaces piston 10 to permit flow out through connection screw 5 and, via the engagement of the enlarged piston end 17 within the bore of sleeve 7, simultaneously prevents leakage via throttle bore 15 and connects valve chamber 29 through bores 19 and 21 to return passage 16, whereby superfluous oil returns to an oil container together with air and gas bubbles which have collected at the deepest region of conical chamber 29. On switching off the pump, the residual pressure suddenly collapses as spring 11 re-establishes connection to bore 15. Channels 33 and 34 extend from either end of the bore to an axial bore in the housing which conducts leakage oil away, so that the valve may be reversed with connection 5 on the other side of the pump housing.

Abstract: 843,732. Automatic temperature-control systems. UNION CARBIDE CORPORATION. Sept. 16, 1958 [Sept. 17, 1957 (2)], No. 29598/58. Class 38 (4). In a system in which two streams of gas, one heated and the other unheated, are supplied to a single conduit in which there is a fixed restriction, the resulting temperature is maintained constant, automatically, by adjustment of a pressure regulator in one of the streams in dependence on that temperature, a pressure regulator in the other stream varying the flow in that stream in the opposite sense. In Fig. 1 a conduit 30 supplying gas to an instrument chamber 20 has a fixed restriction orifice 14 and receives two streams of gas from a common source through regulator valves 10 and 12 respectively. The stream passing through regulator valve 12 also passes through a heater 32, which may be electric, and valve 12 is automatically controlled by an electric or pneumatic thermostat 18 so that the flow of heated gas is adjusted to stabilize the temperature in chamber 20. Changes of pressure drop across valve 10 resulting from regulation of valve 12 alters the flow through valve 10 in the opposite sense and if, as in one modification, valve 10 is of the type which operates automatically to maintain a predetermined constant outlet pressure, flow through it ceases if the adjustment of valve 12 causes the pressure on the outlet side of valve 10 to exceed a value just above the predetermined pressure. An alternative arrangement, in which the other stream is heated instead, is referred to.

Abstract: 1,177,422. Valves. ROBERTSHAW CONTROLS CO. 28 June, 1967 [1 July, 1966], No. 29908/67. Heading F2V. A plug cock that may be turned either to left or right of its " off " position to open either of two different outlets has a stop device to prevent turning the plug directly from one " open " position to the other without pausing at the " off " position. A spinde 2 is pushed axially to release it from a locked off position and cause a lug 3 (Fig. 1, not shown) to operatively contact the plug. At the same time a pin 6 moves between projections 7a. 7b. When the spindle is turned, a cam 7 pivoted at 8 turns and after a certain degree of rotation the projections are released by the pin so that the cam is returned to its rest position by a spring 9. When the spindle is turned back towards the off position it again contacts one of the projections 7a, 7b, thus causing one of lugs 7c, 7d on the cam to engage shoulder 5 in the off position of the valve to prevent further rotation. The spindle must be allowed to move axially to the locked off position, free of the cam, before further rotation can occur. In a modification, the cam is replaced by two elements 10, 11 (Fig. 4) pivoted at 8a, 8b and biased by a spring 9. The pin 6 is initially between them and the device locks when one element is pushed by the pin in one direction and by the second element in the reverse direction (see Fig. 5). In a further modification, Fig. 8, a U-shaped element 13 replacing the cam 7 has flexible limbs reinforced at 13c, 13d and claws 13e, 13f which register in notches 13h in their opposite limbs to lock the two limbs together at the off position. In a final modification (Fig. 11), the plug operating lug and the pin are one and an elastic spring blade 7<SP>1</SP>, replacing cam 7, extends through a slit 14a in an annular shoulder so that in the off position the projections 3b on it abut the edge of the slit.
