Title: Method of Manufacturing Ring-Shaped Metal Magnetic Cores
IPC: H01F41/02
Filed: 1968-08-27
Abstract: 1,194,468. Making magnetic storage cores. FUJITSU Ltd. 27 Aug., 1968 [28 Aug., 1967], No. 40971/68. Heading B3A. [Also in Divisions H3-H5] A matrix of magnetic storage cores is formed by providing a layer of magnetic material on the surface of a wire core, arranging a plurality of the layered wire cores in parallel and inserting them into a mould material which is subsequently hardened to affix the wires, cutting off the ends of the layered wire cores which project from the hardened mould material, and removing the wire cores so that ring-shaped magnetic cores remain embedded in the hardened mould material. An additional manufacturing step is to remove the hardened mould material so that separated magnetic ring- shaped cores are left, each core being strengthened by an internal support initially provided on its core wires. Each storage core may consist of two concentric layers of magnetic material each having a different coercive force, the two layers being applied consecutively on the surface of the core wires during manufacture. A conductive layer may be provided under the magnetic material which remains in position when the wire cores are removed, the conductive layers 12, Fig. 5, being subsequently interconnected by conductive films 13 deposited on the surface of the hardened mould material. The magnetic storage cores may be thin magnetic films which are made circularly anisotropic by passing a current through a wire core while the magnetic layer is applied. The mould material may be either a resin or a metal of low melting point. The wire cores may be of a copper alloy such as beryllium copper or phosphor bronze and are removed by applying a mixture of chromic and sulphuric acids. If a concentric conductive ring is provided for each storage core, the ring is formed of a material, such as gold, not affected by the wire core removal process. Alternatively the conductive rings may be applied afterwards by plating, sputtering or evaporation, with or without an insulating layer between the conductive rings and the magnetic material.

Title: Method of making fluorescent lamps
IPC: C09K11/02
Filed: 1971-09-08
Abstract: 1363478 Coated fluorescent lamp envelope G T E SYLVANIA Inc 8 Sept 1971 [28 Sept 1970] 41953/71 Heading B2E [Also in Division C4]  A process of coating a fluorescent lamp envelope comprises coating on the envelope wall a suspension of the phosphor in an organic binder and solvent and zone drying to obtain a coating of substantially uniform thickness. Zone drying is defined as locally heating a portion only to evaporate solvent and transferring the heated zone along the envelope progressively until the entire coating has been dried. Movement may be continuous or stepwise. The suspension with aqueous solvent may be flushed into the upper end of a vertical open ended tubular glass enevelope. Phosphor particle size may be 10.1Á average and 5.0 or 4.2 mgrms/cm<SP>2</SP> for example, other densities being given, and yellow pigment may be included. Colour coordinates, temperature and colour rendering indices are disclosed. Zone drying is preferably commenced at the top of the vertical tube, excess suspension flowing down and flow being accelerated by viscosity reduction due to the heating, a vertical disposition also inhibiting flow from higher portions. Solvent evaporation is also more rapid at the air stream inlet end. The initial zone need not be completely dryed but sufficient to prevent movement. The zone length is preferably 5 to 30% the envelope length, and heating interval will depend on velocity, air stream temperature and phosphor suspension, the zone heater being electric or flame and preferably surrounding the tube, and the air stream. may be heated. Continuous heating may be by drawing the envelope vertically through a stationary heater or moving the heater downwards, e.g. at 0.9 cm/sec. Organic solvents may be butyl acetate or ethyl cellulose in xylol. In an example, polymerized ethylene oxide binder was dissolved in deionized water with liquid surfactant, submicron aluminium oxide added and ball milled, mixed with liquid vehicle, deionized water, polyethylene glycol and antimony-manganese activated halophosphate phosphor, producing a S.G. of 1.450 and viscosity of 107 centipoises. Air was drawn up the tube at 300 ft/min. by passing compressed air through a U tube at the top or alternatively at the bottom or by a fan and the envelope then heated in an oven at 550C.
