Filed: 1966-01-27
Abstract: 1,104,136. Magnetic storage apparatus. GOVERNMENT OF THE UNITED STATES OF AMERICA. 27 Jan., 1966, No. 3783/66. Heading H3B. In a magnetic storage device comprising an elongated anisotropic thin magnetic film mounted on a substrate, and in which by propagating a sonic wave through the assembly, discrete storage locations in the film are established where coincidence occurs between the travelling sonic wave and pulses applied to a longitudinal conductor, the effects on the magnetic characteristic due to progressive dissipation of the sonic wave energy in the direction of propagation is neutralized by applying a graded magnetic biasing field. As shown in Fig. 1 a sonic wave transducer 13, e.g. a piezo-electric crystal, and a sonic energy absorber 15 are mounted at opposite ends of a tubular non-magnetic substrate 11 having a deposited thin magnetic film 12. The magnetic film is deposited by evaporation, cathode disintegration or electroplating in a magnetic field which establishes a circumferential easy axis of magnetization. A longitudinal conductor 16 passes through the centre of the tubular substrate and is connected to a writing generator 17 and a read-out detector 18. The bias field acts longitudinally of the assembly and is produced by a coil 19, the turns of the coil being graded so that the turn density increases in the direction of sonic propagation. Writing in is effected by energizing generator 17 and simultaneously activating the transducer 13 by a pulse source 14. Non-destructive read out in conductor 16 is obtained by activating the transducer alone. The assembly may alternatively comprise a flat substrate and thin magnetic film.

Title: Improvements in the cooling and thermal insulation of the tools of extrusion presses
IPC: B21C23/32
Filed: 1962-02-02
Abstract: 979,462. Extruding. SCHLOEMANN A.G. Feb. 2, 1962 [Feb. 14, 1961], No. 4052/62. Heading B3P. In an extrusion process, the press tools whilst hot are coated with a paste-like suspension of a heat-insulating substance in a liquid which evaporates below the extrusion temperature thereby to cool the tools. The substance is preferably asbestos fibre or powder graphite, alumina, mica, glass powder or silicates to serve as an extrusion lubricant; the liquid is preferably water. This substance at 15 is applied to the container bore and at 16 to the mandrel before the hot billet 10 is introduced. The tools which are still hot from a previous operation cause evaporation of the water with consequent cooling of the tool. When the billet is introduced, the substance at 15 is spread into an even layer 15b and is pushed forwards on to the die face, Fig. 3 (not shown). The substance may also be applied to the face of the press disc, Fig. 5 (not shown). It provides a heat insulation to protect the tools from the billet heat. After extrusion a cleaning disc may be passed through the cylinder bore.

Title: Improvements in the continuous production of hydrochlorides of cycloaliphatic ketoximes
Inventor: SCHICKH OTTO VON
Filed: 1959-02-05
Abstract: Cycloaliphatic ketoxime hydrochlorides are prepared by the action of nitrosyl chloride or of nitrogen monoxide and chlorine on a cycloaliphatic hydrocarbon having 5 to 10 carbon atoms in the ring in the presence of hydrogen chloride while irradiating with active light where before the reaction commences or before the reaction subsides there is added such an amount of a mixture of by-products such as are obtained as a residue from the reaction mixture arising in a reaction of cycloalkanes with a nitrosation agent of the above mentioned kind after removal of the oxime hydrochloride and the excess reactants, so that the content of organically combined chlorine in the reaction solution is at least 0,5% by weight with reference to the amount of cycloalkane used. The addition of the by-products is said to prevent the formation of a yellow coating on the lamp or glass parts of the reactor which slows down the speed of reaction.  The nitrosation residues used generally contain 20 to 40% by weight of organically combined chlorine and are preferably added so that the chlorine content is 0,5 to 5% based on the hydrocarbon.  The reaction is otherwise carried out in known manner and the examples describe the preparation of the oxime hydrochlorides, of cyclo-hexanone and cyclo-octanone.
