Title: A Method for Making a Ferromagnetic Film having Uniaxial Anisotropy
IPC: H01F41/20
Filed: 1968-11-06
Abstract: 1,193,908. Magnetic storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 6 Nov., 1968 [14 Dec., 1967], No. 52479/68. Heading H3B. [Also in Divisions C7 and H1] A ferromagnetic film of, e.g. Fe, Ni, Co, Fe- Ni, Fe-Co, Fe-Ni-Co, rare earth metals, e.g. Gd, No, Dy and Tb, oxides, e.g. EuO, nitrides, e.g. GdN, tellurides, e.g. EuTe, or sulphides, e.g. EuS is vapour deposited in an electric field to produce uniaxial anisotropy in the plane of the film, on a quartz or glass substrate. The field is formed by applying a potential between adjacent parallel Cu, Ag or Au conductors on the substrate. An information system showing only a single circular or rectangular film 11 on a substrate 12, e.g. an electrically conductive ground plane with an insulative layer thereon, is shown in Fig. 7. A bit line 50 is deposited on the film orthogonally to the easy axis and a word line 52 is deposited parallel to the easy axis. The lines 50, 52 may be strip lines and a layer of silicon monoxide may be interposed between the lines. The line 50 can be switched at 54 to a bit driver or earth and at 56 to a load 60 which may be a sense amplifier or earth. The line 52 is connected at one end to a word driver 62 and at the other end to the characteristic impedance 64 of the line 52. The switches 54, 56 are so ganged that with one end of the line connected to the driver 58 the other end is connected to ground. Instead of using switches 54, 56 a third line similar to line 5 may be used as a sense line. The film may be used for a laser or electron beam addressable memory system, the information being retrieved by an He-Ne laser.

Abstract: 1,124,820. Drilling machines. CHEMCUT CORP. 10 Dec., 1965 [24 Dec., 1964], No. 52493/65. Headings B3B and B3C. [Also in Divisions G3, G4 and H2] A carriage of a machine tool is rectangular co-ordinately positioned in response to a pneumatically read punched tape or manually set switches by a system wherein desired large position increments are set on a potentiometer and small position increments by the displacement of a final position sensor by a pneumatically actuated decimal gauge assembly. As shown, a drilling machine has a tool head 24 carrying a vertically fed drill bit 26 and a workpiece is moved by point to point positioning by a table 20. An X-axis motor through a lead-screw 30 moves the table 20 with respect to a saddle 32, which is positioned through gearing and a lead-screw 36 with respect to a base 22 by a Y-axis motor 34. The saddle is provided with flexible rubber mats 46, 48 forming aprons to collect and convey to the side, drilling chips. A console type programmer 50 is connected to the machine by a conduit 52 and runs the drill automatically from coded perforations read by a tape reader 54 or manually by a manual dial input 54 having settable dial markings which read directly in cardinal and decimal co-ordinates. The motors 28, 34 are permanent-magnet low-inertia printed circuit motors which are caused to have slight dither in the stopped position. The motors are controlled by the manual or programmed position signals through silicon-controlled rectifiers.

The optically active phthalimidiacids can be obtained by optical resolution of the corresponding racemic acid, e.g. by fractional crystallization of its ephedrine salts, or by reacting the appropriate phthalic anhydride with an optically active a -amino-acid of formula RCH(NH2)COOH.  Therapeutic compositions which are useful as tranquilizers and anticonvulsants and which may be administered orally, e.g. as tablets, pills, wafers, or cachets, contain as active ingredient the compounds described above.

Title: Arc discharge lamp

Filed: 1964-12-31
Abstract: 1,026,069. Discharge lamps. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 31, 1964 [Dec. 31, 1963], No. 53057/64. Heading H1D. An arc discharge lamp, particularly a fluorescent lamp, having an electrode filament supported by leads 3, 4 extending through stem 2, has a conductor 13 extending from an internal part 3b of one of the leads to a thinwalled portion 2a of the stem adjacent an external part 3a of the lead, so that if the electrode filament burns out, the arc is directed by conductor 13 through wall portion 2a to external lead 3a, and is extinguished by perforation of the wall. This arrangement prevents overheating of internal parts of the electrode support which might break the side walls 1 of the envelope, and prevents a weak flickering discharge which might damage the current-limiting ballast in the lamp fitting. The nickel-plated iron wire conductor 13 shown may be replaced by a conductive coating on the stem comprising colloidal graphite or nickel powder in a potassium silicate binder. The electrode filament may be associated with an auxiliary electrode, Fig. 1 (not shown), and is mounted in front of a shielding disc 11. A base 7 with terminals 5 is cemented to each end of the lamp.

Title: Process for the resolution of alpha-arylalkylamines into their optical antipodes
Filed: 1966-12-02
Abstract: The invention comprises a method of separating optical isomers of amines of the formula NH2CH(R2)CH2R1, in which R1 denotes hydrogen or an alkyl group of 1-8 carbon atoms and R2 denotes a monocyclic aryl group, which may be substituted, or a bicyclic aryl group having six carbon atoms in each ring.  The method involves the formation of a Werner complex of nickel thiocyanate with two or four mols. of the amine and the formation of a clathrate from the complex, as described in Specifications 931,775, 935,099, 937,791, 945,012, 994,026 and 994,027.  In the method of the invention, an amine of the formula above containing an excess of either the d- or l-isomer is caused to react with a clathrated Werner complex in such proportions and under such conditions that the dl-form of the amine reacts with the nickel thiocyanate and, after formation of a solid clathrate and separation thereof, e.g. by filtration, the excess of d- or l-isomer remains in the liquid phase.  The examples describe the treatment of a -phenylethyl amine, a -phenylpropyl amine, a -(m-chlorophenyl) ethyl amine and a -phenylisohexyl amine, a d-isomer being separated in each case.
