Title: Circuit arrangement and method for writing magnetic information
IPC: G06K1/12
Filed: 1954-11-10
Abstract: 757,684. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 10, 1954 [Nov. 13, 1953], No. 32530/54. Class 106 (1). Magnetic recording of binary information is effected on a surface by energizing all of a group of writing heads with equal currents of one sense and simultaneously energizing selected heads with currents of greater magnitude and opposite sense, the selected and unselected heads recording the two digits respectively. The writing coils of seven writing heads each have two sections 10 and 14. When the group of magnetic writing heads is selected by the application of a " channel" " signal and a " write " signal to an " and " gate 31, parallelconnected triodes V2 and V3 pass a current i through each of the coil sections 10. The " channel " and " write " signals are also applied to a series of "and" gates, e.g. 58 and 66, associated with tubes, e.g. VI, each connected to a corresponding coil section 14. When a " write 1 " signal is also applied to " and " gate 66, the two sections of the tube V1 conduct and a current 2i is applied to the corresponding coil section 14. This current opposes the current in the coil section 10 and a " 1 " is written by the corresponding head. Those writing heads in which the coil section 14 is not energized write a " 0." The gate circuits shown are formed by biased germanium diodes.

Patent GB-370026-A (GB)
Title: Improvements in or relating to the refining of metals
IPC: C22B13/06
Filed: 1930-10-31
Abstract: A process for removing silver and bismuth from molten lead is provided in which the silver is removed by zinc and the bismuth by an alkaline earth metal.  The excess of zinc and the alkaline earth metal are removed as chlorides by the addition of chlorine to the bath.  In carrying out the process sufficient zinc is added to form a silver dross, which, after pressing, is removed.  The bath is cooled, zinc plates are added and the further dross formed is cast in blocks suitable for desilverizing subsequent lead baths.  After further cooling to about 650 DEG  F., calcium, preferably as a lead calcium alloy, is added to the bath to form a bismuth-calcium-lead-zinc dross which is removed.  By still further cooling the bath more blocks of zinc silver dross are formed.  On now adding chlorine to the bath the first slags formed contain all the excess calcium with a little zinc and may be used for treating the bismuth dross.  The final slags are free from calcium.  The bismuth dross may be treated by melting under a zinc chloride calcium chloride slag at about 1000 DEG  F. whereby the calcium enters the slag reducing an equivalent amount of zinc. The calcium-free bath may be treated by liquation for the removal of zinc, the solid crusts being retorted to recover zinc.  The residue from the retorts is combined with the calcium-free bath and treated with chlorine to remove any zinc as zinc chloride which may be used with calcium chloride to treat the bismuth dross.ALSO:A process for removing silver and bismuth from molten lead is provided in which the silver is removed by zinc and the bismuth by an alkaline earth metal.

Abstract: 944,491. Water supplies. S. L. ELBORNE. Nov. 9, 1962 [Sept. 14, 1961], No. 32970/61. Heading E1X. [Also in Division F4] An expansion tank in a hot water central heating system has a floating layer 14 of oil on the surface of the water to inhibit evaporation, loss of the oil through the overflow pipe 12 being prevented by connecting the overflow to an intermediate point on a length of pipe 15 having an upper port 16 open to the atmosphere and a lower port 17 in free liquid communication with the interior of the tank below the normal minimum water level. As shown in Fig. 2, the pipe 15 has a further branch connection 19 above inlet port 17 to the feed pipe connection 11; this prevents the entry of the oil into the pipes of the heating system when the tank is drained, since the outflow will cease when lever el is reached. Fig. 4 shows an overflow arrangement for fitting in an existing tank. The pipe 15 is supported on the tank by a metal strip 21, and is connected to the overflow pipe 12 by a flexible hose 24 and rubber collar 25. The lower end of the pipe contains a pipe section 20a having the same function as connection 19 (Fig. 2), this pipe section being supported by spacers 22 and connected by rubber collar 23 with the feed pipe 11.
