Title: Improvements in or relating to solid electrolytic capacitors
IPC: H01G9/00
Filed: 1965-01-14
Abstract: 1,055,362. Solid electrolytic capacitors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 14, 1965 [Jan. 17, 1964], No. 1680/65 Heading H1M An anode of filmforming metal having a dielectric oxide coating is folded, stacked or wound into a packet with interposed layers of separating material impregnated with semiconducting oxide, the packet being surrounded by a metal cathode which is in contact with the semi - conducting oxide. As shown, aluminium or other value metal foil 4, which may have been etched or provided with macroscopic perforations, has a dielectric oxide layer 60-100 microns thick and is folded on a zigzag manner with strips of separating material 6, e.g. glass fabric 30-100 microns thick provided on both sides of the foil. The formed packet fits into metal casing 1 closed at the upper end by insulating covers 2 and 3. The separating material 6 is impregnated in vacuo with manganese nitrate from which manganese dioxide is formed on heating. A wound anode may be used in a feed-through capacitor (Fig. 5, not shown).

Title: Improvements in or relating to metered dispensing containers
Inventor: SILVER STAN M
IPC: H02M7/36
Filed: 1958-01-17
Abstract: 844,196. Delivering measured quantities of granular materials. SILVER, S. M. Jan. 17, 1958 [Jan. 22, 1957], No. 1723/58. Class 106(5) [Also in Group XVII] A carton from which measured quantities of granular or powdered materials can be dispensed is made from a single cardboard blank (see Group XVII) and comprises an exit shoot 54 extending part of the height of the container, a metering chamber 55 immediately below the shoot and of greater cross-section and capacity than the shoot and a supply chamber 56 which is of greater capacity than the metering chamber and has a flap bottom 43 forming a one-way valve between the supply chamber and the main body 59 of the container. On tipping the container, the contents of the measuring chamber are discharged through the shoot and as the container passes the horizontal position, the flap 43 moves against a bent-out stop 70 to allow the supply chamber to be filled. When the container is returned to the upright position, the flap closes and the measuring chamber is refilled from the supply chamber 56 through the opening 58 provided because of the greater cross-section of the measuring chamber compared with the shoot. When the container is initially filled with material, from the bottom, the shoot supply chamber and measuring chamber are substantially filled and, to allow the excess in the shoot to return gradually to the main body 59, the flap 43 is not a close fit in the chamber 56. A tearoff flap and knockout piece normally close the shoot and a several radiating scored or cut lines 75 are provided on the flap 43 so that the edge of the stop 70 may engage in one of them and prevent the stop from being folded back by the valve.

Abstract: 361,701. Pressure-regulating valves. FORRESTER, H. J. C., 88, Chancery Lane, London.-(Pintsch Akt.-Ges., J. ; 71, Andreasstrasse, Berlin.) Jan. 19, 1931, No. 1770. [Class 135.] In a gas pressure regulator of the kind in which the valve 17 is controlled by a diaphragm 14 associated with a breathing chamber III having an automatically obturable aperture 33, the walls 10<a>, 15, cover 13 and diaphragm 14 forming the boundaries of the inlet chamber I, pressure chamber IV and breathing chamber III are formed of sheet metal united by a common flange 12, while the upper portion 15 of the casing is designed to contain means for closing the aperture 33 in the event of rupture of the diaphragm 14. As shown the latter closure device comprises a flexible plate or valve 37 co-operating with a seating 41 and dividing a chamber 32<x> into upper and lower compartments 32, 32<a>. When the regulator is in use air enters the chamber III through passages 30, 31, chamber 32, passage 33, past a lift valve 34 and through passages 35, 36 ; expulsion takes place through passages 36, 35, 46, 47<a> lifting if necessary a valve 45. The lower wall 38 of the chamber 32<x> is provided centrally with a permeable diaphragm 39 which, should a considerable increase of pressure be maintained in the chamber III for some time owing to rupture of the diaphragm 14, permits the pressure to be transmitted to the plate 37 and to effect a closure of the aperture 33. For purifying the gas entering the chamber I, the latter is fitted with a sieve 47 and formed with an annular pocket 5 for deposited impurities. Gas pressure at the outlet II is transmitted with some lag to the pressure chamber IV by way of a narrow passage 21 in the valve spindle 16, the cover 13 has a small central diaphragm 18, while the diaphragm 14 is provided with variable loading-means 23.

A milk receiving vessel 1 subjected to vacuum is provided with a lid assembly 2 supporting four milk receptacles 7 each having a cover 13 with a milk inlet port 12, a vent 15 to atmosphere, and an outlet port comprising a tube 8 the outlet opening 17 of which is controlled by a spherical valve 18. A valve actuating member 20 is secured in a resilient plug 21 in the cover and is attached to an operating mechanism by which it is moved, because of the resilience of the plug, to unseat the valve 18 to apply vacuum to the port 12. With the inflow of milk a float valve 16 surrounding tube 8 rises and supports the valve 18 clear of opening 17 by means of prongs 19. The milk flows into the vessel 1 through tube 8 and opening 9 in the base of receptacle 7, the float 16 falling to seal opening 9 and allow valve 18 to reseal tube 8 after the flow of milk ceases. The operating mechanism for members 20 comprises a flexible spider 24 slidable on post 26 by means of handle 27 to flex the arms of spider 24 to move the members 20. The lid may be applied to a large milk pail or to a small container adapted to be supported from a surcingle or belt attached to a cow. Means may be provided for supporting the container clear of the ground.
