Title: Process for treatment of manganiferous iron ores
IPC: C22B1/02
Filed: 1951-03-29
Abstract: The process of the parent Specification is applied to the concentration of manganiferous iron ore in which the manganese is present in the iron mineral proper, the resulting magnetic concentrate containing manganese as oxide.  The degree of dry thermal reduction may amount to as much as 90 per cent of the iron in the ore.  The concentrate may then be subjected to treatment in a smelting furnace in which either the manganese and iron are both reduced to metallic form or substantially only iron is so reduced, the manganese for the most part remaining in the slag. Alternatively, the concentrate may merely be melted to separate molten metallic iron from slag containing iron oxide and manganese oxide.  The manganiferous slags may then be reduced to produce spiegel or ferromanganese.  Specification 636,677 is referred to.

Abstract: 526,067. Rolling-appliances. WALKER, J. H. March 7,1939, No. 7450. [Class 78 (ii)] [Also in Group XXXII] A vehicle to be displaced laterally is run with its back wheels 18 on to the members 1, 2 which are spaced adjustably by the screw-and-nut mechanism 14. Each member comprises a pair of ball races 5 of which the middle portions of the inner straight runs carry the groundengaging balls, as shown in Fig. 3, the ends of these runs being curved upwards as shown. The balls circulate in the races as the appliance is hauled by the handle 17 with the vehicle on it. To remove a car from a rank, the back wheels are run on to the appliance and the car then moved in a circular path by hauling on the handle 17. On starting the motor in reverse gear, the rear wheels push the appliance forward from under them so that it can be removed to allow the car to back out under its own power. In some cases two appliances may be used, one for the front and the other for the rear pair of wheels, and in other cases the two appliances may be combined as a single appliance with one large ball race common to all the road bearing surfaces.

Title: Improvements in and relating to methods of applying insulating coatings of varnish
IPC: B05D3/14
Filed: 1931-03-11
Abstract: Metal to be coated with insulating varnish is subjected to a strong electric field in order to remove gas or moisture from the surface and secure more complete wetting by the varnish.  The metal may also be heated in gases, in a vacuum or in a liquid, or in the oil which is used as a varnish.  The electrical treatment is preferably effected while the metal is immersed in the varnish. In the example, a wire to be varnished is earthed and is surrounded by a ring-shaped electrode within the oil.  The electrode is surrounded by a solid insulating substance such as glass, and is brought to a high voltage preferably producing a field of greater strength than the testing field for the finished wire.

IPC: G11C5/02
Filed: 1968-02-17
Abstract: 1,263,271. Magnetic storage apparatus. E.M.I. Ltd. 25 March, 1969 [17 Feb., 1968], No. 7877/68. Heading H3B. A non-destructive read-out magnetic storage element comprises three anisotropic magnetic thin films 1, 2, 3 overlying one another with their easy axes parallel to arrow 4 and an address conductor 5 and digit conductor 6 arranged parallel to and orthogonal to the easy axes respectively. When a signal is applied to address conductor 5 a closed flux path 8 is formed round the conductor rotating the magnetizations of films 1 and 2 parallel with the hard axes of the films and inducing a signal in digit/sense conductor 6 depending on the binary digit stored in films 2, 3. The magnetization of film 3 is only partly rotated from the easy axis so that when the address signal terminates the magnetization of film 3 returns to its original position and this in turn is effective on the film portion 2 to return it also to its original position because of the closed flux path 7. Film 1 becomes demagnetized in the absence of the address pulse. To write information into the storage element a digit drive signal is applied to conductor 6 straddling the trailing edge of the address pulse. A magnetic keeper portion of ferrite may be provided underneath but separated from film 3 to assist in the rotation of the magnetization of film 3 during an address drive signal and to reduce any residual flux flowing around conductor 6 due to the magnetization of film 3 by itself. Separate digit and sense conductors may be used. A plurality of elements may be arranged in a matrix.
