Title: Improvements in or relating to circuit arrangements for operating electric lamps
Inventor: DUNHAM CARLTON ROSSLYN
IPC: G05F1/32
Filed: 1958-06-26
Abstract: 860,107. Magnetic amplifiers. GENERAL ELECTRIC CO. Ltd. June 9, 1959 [June 26, 1958], No. 20512/58. Class 40 (9). [Also in Group XXXV] An A.C. circuit arrangement for operating one or more electric lamps at various levels of brightness which, relative to maximum lamp brightness, are made principally dependent on the magnitude of a control current and independent of the lamp wattage, contains two magnetic amplifier stages. A first amplifier stage comprises A.C. terminals 18, 19 connected through oppositely-directed windings 15, 16 to the lamp terminals 20, 21 across which are connected in series resistance 26, rectifier 25 and a negative feed-back winding 9 on a second amplifier stage. The second amplifier stage comprises A.C. terminals 1, 2 connected through windings 3, 5 to the A.C. terminals of a rectifier bridge 4 whose D.C. terminals are shunted by a condenser 24 across which are connected in series positive feed-back winding 10, a control winding 17 of the first amplifier stage and resistance 23, winding 17 being wound over windings 15, 16 to link with their cores. The arrangement is completed by a circuit comprising D.C. terminals 7, 8 feeding control winding 6 which is wound over windings 3, 5 to link with their cores. Any change in lamp wattage produces a change of voltage between lamp terminals 20, 21 which, through winding 9, produces a compensating change in the current through windings 10, 17, thus restoring the lamp terminal voltage to its original value and making the ratio of lamp brightness to maximum lamp brightness virtually independent of wattage for a given control current through winding 6. A further circuit comprising D.C. terminals 12, 13 feeding variable resistance 14 and bias winding 11 may also be included in the arrangement to give maximum lamp brightness at the desired control voltage across terminals 7, 8.

Title: Manufacture of superconductors
IPC: C22F1/00
Filed: 1975-05-16
Abstract: 1470942 Making superconductors SIEMENS AG 16 May 1975 [16 May 1974] 21022/75 Heading B3A [Also in Division H1] A conductor structure comprising a first component containing a superconductive compound, bound to a second component containing a good normal electrical conductive metal and an element of the superconductive compound, is subjected to a chemical transport reaction (i.e. a solid or liquid is transported by reaction with a gas to yield a gaseous compound which is transported), to deplete the amount of the element in the second component. In an example, a ribbon conductor with 220 Nb 3 Sn cores in a copper-tin matrix was placed in a quartz ampoule with copper wire as getter, and the ampoule evacuated, filled with HCl at a pressure of 0À05 Torr at room temperature, and sealed by fusion. It was heated for 48 hours, with the conductor at 750 C. and the getter at 730 C., whereby tin was transported as the chloride, and deposited in the getter, improving the normal conductivity of the matrix. In another example, a multi-Nb 3 Sn-core conductor 1 is wound on to a ceramic tube 2 pushed on to the re-entrant portion 4 of an ampoule 3. A copper tube getter 5 surrounds the tube 2. Using HCl as before, heater 5 heats the conductor 1 to 750 C., and heater 7 heats the getter to 740 C. Where the superconductive compound is V 3 Ga in a Cu-Ga matrix, Ga is removed using I as the transport medium.

Abstract: 823,684. Counting apparatus. BIRD, W. G. Oct. 20, 1955 [July 20, 1954], No. 21174/54. Class 106 (1). [Also in Group XXIX] Voltage pulses alternately positive and negative in sign and of amplitude substantially independent of pulse rate are applied in push-pull to the grids of two thyratrons 60 so that each pulse causes one of them to fire and discharge its anode capacitor 63 or 64 into a much larger capacitor 62 in the common cathode circuit, the leakage current of which through the field windings 69 of D.C. motors 70 is a measure of pulse rate and is integrated by mechanical counters 72 driven by the motors 70, which counters therefore effectively count the applied pulses. The arrangement is described as applied to the integration of fluid velocity to give a measure of fluid flow, the pulses being produced by differentiation of a square waveform produced by a member 35 oscillating in the flowing fluid ; meters 68 provide a measure of the fluid velocity. The desired proportionality between the field current of the motors 70 and the angular velocity of the armature produced is ensured by the use of eddy-current brakes 71 producing a braking torque proportional to angular velocity; two meters 68 and counters 72 are shown connected in series as a illustration of the provision of flow rate and integrated flow repeaters. The use of other known types of counter is described. Specifications 384,703 and 422,202, [Group XXXVI], are referred to.

Abstract: 1292097 Water-insoluble acylase complexes TANABE SEIYAKU CO Ltd 19 April 1971 [3 Feb 1970] 21345/71 Heading C3H A water-insoluble mould acylase complex of a substantially water-insoluble haloacetyl-polysaccharide has hydrolysing activity such as to hydrolyse an alpha-N-acyl derivative of a racemic amino acid selectively to yield the free L-amino acid. Examples of haloacetyl polysaccharides which may be used are bromoacetylcellulose, bromoacetyl - dextrane, bromoacetylagarose, chloroacetyl - cellulose, chloroacetyldextrane, chloroacetyl - agarose, iodoacetylcellulose, iodoacetyl-dextrane and iodoacetylagarose. Particularly preferred mould acylases are those produced by Aspergillus oryzae or Penicillium vinaceum. The water-insoluble complex may be produced by treating the mould acylase with the water-insoluble haloacetyl polysaccharide in the presence of a protein salting- out agent such as ammonium sulphate. A method of producing a free L-amino acid from a racemic amino acid comprises incubating a solution of an alpha-N-acyl-derivative of the racemic amino acid in the presence of waterinsoluble mould acylase complex to form free L-amino acid in the solution. In a further method of resolution, the solution of the alpha- N-acyl derivative of the racemic amino acid in an aqueous medium is flowed continuously through a column of the acylase preparation and the resulting free L-amino acid and alpha- N-acyl-D-amino acid in the effluent are separated.
