Abstract: 1,114,491. Capacitors. EBASON DENKI KABUSHIKI KAISHA. 18 May, 1965 [20 May, 1964], No. 20990/65. Heading H1M. A capacitor electrode has a semi-permeable membrane on the surface thereof and in the case of an electrolytic capacitor, the membrane may be on the electrode bearing the anodized oxide layer. The membrane is formed from nitrocellulose, polyvinyl alcohol, polyethylene oxide, methylcellulose, alkali metal celluloses, acetyl cellulose, collodium oxides or gelatine by applying a solution, emulsion, suspension or dispersion to the electrode plate or by forming the membrane independently and then applying it to the plate. An ionic semi-permeable membrane may be formed by blending a pulverized or liquidized ion-exchange substance with one of the above substances, or by applying a solution of ion-exchange substance on the membranecovered base. The ion-exchange substance may be sulphonated polystyrene optionally containing quaternary basic groups. The membrane may also be formed by treating a solution of e.g. ethyl polysilicate applied to the electrode to form a bridged network of silica oxygen atoms. Other monomeric or polymeric organic silicon compounds may be used. The membrane may also incorporate inorganic oxides such as alumina, stannous oxide and titanium dioxide. As shown, an etched aluminium, tantalum, titanium or niobium foil la having layers 2 of oxide formed by anodizing in ammonium borate is the negative electrode of the capacitor. The positive electrode has semipermeable layers 3a and 3c of polyvinyl alcohol and 3b of nitrocellulose. The membranes are impregnated with electrolyte. In an alternative construction (Fig. 11, not shown) the semipermeable membrane is deposited directly on the oxide layer.

Abstract: 358,163. Trueing brake-drums. DEHN, F. B., 103, Kingsway, London.- (Barrett Co., Ltd., H. B. ; 6605, Iris Drive, Los Angeles, U.S.A.) July 18, 1930, No. 21813. [Class 83 (iii).] Portable turning apparatus.-A machine for trueing brake-drums of vehicle wheels comprises a fixed support or arbor A mounted coaxially with the drum D of a wheel W and a toolholder which is rotatable around the drum and is fed axially to carry the tool across the periphery of the work. The arbor is positioned by means of a mandrel 12 provided with adjustable cones 13, 14. A carriage C slides on a key 17 on the arbor A and is connected through ball thrust bearings 22, 23 to a toolholder H which thus partakes of the sliding carriage movement but which may be rotated around the arbor A. The bearings are retained against a flange 20 of the toolholder by means of pointed screws 24 which are adjustable to take up wear. The tool 18 is secured to a shank 26 mounted in a bar 28 which has a sliding movement in the toolholder, this movement being effected by means of a screw 31 mounted in a yoke 33 secured to the head 29 of the toolholder. An electric motor M supported on the carriage C is connected through pulleys 36, belt 37, pulleys 38, shaft 39, and worm 42, to a worm wheel 43 on the toolholder which is thus rotated around the work. For feeding the tool axially of the work the worm 38 engages with a second worm-wheel 44 on a vertical shaft 45. connected by worm gearing 48 and bevel gearing 53 to a vertical screw 54 engaging a nut 57 adjustably secured to the arbor A. The shaft 45 has a limited angular movement about a pin 47 so that the worm 48 may be disengaged from its wheel and the tool returned on completion of a cut by rotating the feed screw from a handle 59. The position of the shaft 45 is determined by a pin on a lever 62 which is engageable selectively with annular grooves 64, 65 on the shaft 45. The cut is normally made during the upward movement of the tool and in order to give audible warning to the operator on completion of a cut an adjustable cranked trip-rod 71 is adapted to be engaged by an arm to ring a bell 67. At the same time the arm 74 of the trip-rod operates a switch 68 to cut off the motor current and stop the machine. As a further safety precaution the feed screw has a reduced end portion 66 which enters the nut 57 and prevents upward feed of the tool beyond a predetermined position.
