Title: Encapsulated capacitor
IPC: H01G9/08
Filed: 1963-10-24
Abstract: 1,047,588. Capacitors. P. R. MALLORY & CO. Inc. Oct. 24, 1963 [Nov. 16, 1962], No. 41983/63. Heading H1M. [Also in Division B5] In a method of encapsulating an electrolytic capacitor, the capacitor body 1 is oriented within a preformed casing 7 (Figs. 2, 3, not shown) so that only the terminal wires project therefrom, the components are positioned in the cavity of a mould form 8, the outside dimensions of the casing creating a line to line fit with the inside dimensions of the mould cavity, and thermoplastic material is introduced into the mould cavity so as to effect complete coalescence with the preformed casing producing a unitary capacitor capsule adhering to the terminal wires to form a tight seal therewith, the internal gas pressure being allowed to dissipate through the moulding. Fig. 8 (not shown) illustrates the enclosure of a miniaturized capacitor 15 in a thermoplastic encasement member 19, both components resting in a mould cavity 24. The member 19 has recesses for the location of terminal wires 17, 18, the wires being retained during moulding by screw clamps 28, 29. Thermoplastic material is again introduced to surround the capacitor body, complete top and side closures and create perfect fusion with the preformed casing. Suitable thermoplastics are fibre filled (e.g. asbestos) polypropylene and polyethylene compounds. The capacitor may be (1) of convolutely rolled aluminium foils with a paper separator and ethylene glycol/boric acid electrolyte, or (2) a sintered tantalum anode solid electrolyte type.

Abstract: 1,068,557. Photographic emulsion stripping methods. EASTMAN KODAK CO. Oct. 29, 1963 [Oct.29, 1962; Aug.21, 1963], No.42538/63. Heading G2C. A method of transferring a photographic emulsion from one support to another comprises heating the emulsion in contact with both supports, in the absence of solvents, to such temperature that it becomes adhesive and adheres to the receiving support and then separating the supports. The heat may be applied dielectrically, ultrasonically or by means of infrared radiation. The two supports may be held together under pressure while being heated. A subbing layer may under lie the emulsion on its first support. The invention may be used to remove and replace frames in a film strip or to remove and/or add information to a record card. In the latter case the emulsion may be transferred to a transparent window in the card which serves as a protective surface for the emulsion.

Abstract: 1,198,677. Depositing active material in electrode matrices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 Sept., 1967 [27 Sept., 1966], No. 43415/67, Heading H1B. [Also in Division C7] A porous electrode matrix is filled with active material by placing it between and in contact with two solutions each containing a reaction component from which the active material is formed by electrolytic precipitation in the pores of the matrix. Preferably an electrode which supplies a reaction component is used. The matrix may be filled with a solution, preferably a thickened solution, containing a reaction component which is not transported through the precipitate. A permeable diaphragm may be arranged abutting against one of the sides of the matrix to prevent mixing of the solutions, and the diaphragm may be a second matrix filled with a thickened alkali hydroxide solution. The solution containing the component transported by the precipitate may contain an inert salt. In making a nickel hydroxide electrode by electrolytic precipitation with a nickel anode the anolyte may contain chloride ions to prevent passivation when the anode is surrounded by a cation-selective membrane. Electrodes may be produced continuously by passing a sinteredmetal tape (matrix) between and in contact with endless foils impregnated with the solutions. Alternatively the tape is passed over a porous, cylindrical drum filled with one solution and rotating in a bath of the other solution. Examples describe the impregnation of sintered Ni matrices with Ni(OH) 2  and Cd(OH) 2  using one solution of the nitrate of the appropriate cation and as the other solution one containing KOH.
