Title: Process for the manufacture of niobium by electrolysis
IPC: C25C3/34
Filed: 1958-09-17
Abstract: 897,138. Electrolytic production of niobium. CIBA Ltd. Sept. 17, 1958 [Sept. 17, 1957], No. 29769/58. Class 41. A niobium chloride in which the valency of the niobium is less than 4 is electrolysed in an oxygen-free and fluoride-free melt composed of at least one alkaline earth metal halide and/or at least one alkali metal halide. Preferably the electrolyte is a eutectic mixture of sodium and potassium chlorides, and the niobium is introduced continuously in the form of " niobium trichloride " (Nb3Cl8) in the solid state at a rate such that the niobium content of the bath remains constant; the bath may be arranged so that substantial concentrations of niobium are present only in the cathode zone to avoid reaction with the chlorine which is evolved at the anode. Apparatus for carrying out the process consists of a graphite container for the melt constituting the anode, a cathode, for example, a nickel rod arranged within the container so as to dip into the melt, a shallow pot of alumina having an upwardly extending side wall and covering the bottom of the graphite container, and a tube of alumina which surrounds the cathode and is arranged so as to dip within the melt and of which the lower extremity lies below the upper edge of the side wall of the pot. Specifications 873,844 and 880,794 are referred to.

Title: Heat exchanger arrangement for gas-cooled nuclear reactors
IPC: G21C13/00
Filed: 1966-07-04
Abstract: 1,095,209. Reactors. BROWN BOVERI/ KRUPP REAKTORBAU G.m.b.H. July 4, 1966 [July 3, 1965], No. 29995/66. Heading G6C. A heat exchanger arrangement for a gascooled nuclear reactor has the upper ends of gas duets from the reactor core projecting into heat exchanger vessels surmounting the container of the reactor core, vapour generators received in the duct ends, and the gas ducts firmly connected to the core container. Thermal expansion of the gas ducts can take place freely from the core container end into the heat exchanger vessels. The upper ends of the gas ducts are preferably enlarged for the reception of the vapour generators. The gas ducts may be double-walled and serve as preheaters for the liquid medium, e.g. water introduced into the vapour generators. The size of the vapour generators is preferably so chosen that they are capable of being transported inside the reactor building, thus facilitating their replacement. The annular channels between the enlarged upper ends of the gas ducts and the heat exchanger vessels communicate with a cold gas channel provided between the core shielding and the reactor vessel. The gas is drawn out of the cold gas channel by fans which blow it into the core. After the heated gas from the core has passed through openings in a thermal shield and/or a reflecting shield it flows through the gas ducts into the heat exchangers. The gas is subsequently deflected at the top of the gas ducts and flows back into the reactor vessel.

Title: Mechanism for transferring data to and from magnetic drum storage devices
IPC: G06F3/08
Filed: 1955-10-21
Abstract: 803,003. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 21, 1955 [Oct. 25, 1954], No. 30125/55. Addition to 759,760, [Group XXXI]. Class 106 (1). A data transfer system includes a rotatable magnetic drum having a plurality of tracks defined thereon, a source of data, means for transferring data in successive groups of like characters from said source to a first of said plurality of tracks, means for generating a signal preparatory to such transfer of data, switching means for selecting one of the other of said plurality of tracks, and means for transferring data from said first of said plurality of tracks to the selected one of said other of said plurality of tracks during one revolution of the drum in response to the signal generated preparatory to the transfer of data from said source to said first of said plurality of tracks. In the machine described data can be transferred either from a record card via a buffer store " read factor store," Fig. 1, to the main store of a digital computer or from the main store via a second buffer store " punch factor store" to a punching device, both buffer stores being a part of a track on a magnetic drum. The staticization of a " read-in " instruction in a programme control unit 15 causes three operations: (1) first, any data already in the read factor buffer store is transferred to an address in general storage specified by the staticized instruction, the transfer being via a code translator 18 and a read-record head selecting matrix and taking one drum revolution ; (2) secondly, the read factor buffer store is cleared; and (3) finally, a card-feed cycle of a reader converter 13 (such as that described in the parent Specification which is referred to) is initiated from where decimal data, parallel by bit and serial by digit, passes in a biquinary code, to the read factor buffer store. This third operation is actually initiated by the staticized instruction but, being mechanical in nature, it occurs after the first two operations. Once data is in general storage it can be used by the arithmetic unit of the computer as directed by the programme control unit. Read-out of data from general storage also proceeds under the control of a staticized instruction in three stages: first the punch factor buffer store is cleared, secondly the data passes via a code converter 22 to the punch factor buffer store and finally it passes from the punch factor buffer store via a coding output matrix 24 to a card punch. Thus data can be transferred between record cards and general storage while only involving the general storage read/write devices for one rotation of the drum. Specifications 442,534, [Group VIII], 688,383, and 710,554, [Group XL (c)], also are referred to.

[Also in Group XXXV] An amplifier consists of a keyed transistor in series with a resistor 2 the average voltage across the transistor is compared with the input signal the on/off keying ratio being controlled so that the amplitudes of the two signals correspond. The output voltage of the transistor 11 is applied across a capacitor C3, and a portion of this voltage is tapped off a potential divider 16, 17 and compared with the input signal Ur by a pair of: transistors 12, 13 having a common emitter resistor 18. The output of the comparator controls a bi-stable trigger pair 14, 15 so that when the voltage across C3 is greater than the input Ur, the transistor 11 is switched to be fully conducting until the voltage across C3 is approximately equal to Ur, when the trigger pair 14, 15 changes over and the transistor 11 is cut off. The voltage across C3 therefore approximately follows the input signal Ur.
