Title: Contra-rotating plasma system
IPC: H05H1/16
Filed: 1963-10-07
Abstract: 987,540. Thermonuclear apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 7, 1963 [Dec. 10, 1962], No. 39346/63. Heading G6P. [Also in Division H1] Apparatus for producing and heating a plasma comprises an annular outer electrode, a magnetic field generating means providing a plasma trapping field region within the outer electrode which is symmetrical about the axis, a central electrode disposed along the axis and extending into at least one end of the plasma trapping region, an annular intermediate field electrode encircling the axis and projecting into one end of the plasma trapping region, the intermediate electrode being spaced apart from the outer and central electrodes, a high voltage source applying a positive potential to both the outer electrode and the central electrode while applying a negative potential to the field electrode, and means for evacuating the plasma ttapping region and admitting gas to it. In Fig. 1 intermediate electrodes 33 and 34 are disposed coaxially within and insulated from the outer electrode 11 which is surrounded by coils 42 and 43 adapted to produce a magnetic mirror field. A central electrode 24 extends axially through the apparatus and is adapted to supply gas to the discharge space through a valve 27 and apertures 26. The apparatus can be evacuated through a port 48. In operation a high potential source, e.g. 50kV, is connected with its positive terminal to electrodes 11 and 24 and its negative terminal to electrodes 33 and 34. Owing to the high mobility of ions along a magnetic field line, the magnetic field line 46<SP>1</SP> that passes through the ends of electrodes 33 and 34 is at the same potential as these electrodes and forms a virtual electrode. The electric field therefore extends from line 46<SP>1</SP> outwards to electrode 11 and inwards to electrode 24; thus ions on either side of line 46<SP>1</SP> rotate in opposite directions and tend to collide on the line with enhanced relative velocity. Electrons tend to accumulate near electrode 24 and disperse along magnetic field lines due to mutual repulsion; apertures 38 and 39 are provided in electrodes 33 and 34 to allow electrons to follow the magnetic field lines to electrode 11. In a modified apparatus, Fig. 3 (not shown), electrode 33 is omitted and electrode 24 extends from the left end of the apparatus to the edge of the reaction zone, the gas valve being situated at the tip of the electrode. Specifications 985,681 and 985,682 are referred to.

Title: Vacuum metalizing
IPC: C23C14/26
Filed: 1962-10-19
Abstract: <PICT:0964461/C6-C7/1> In a continuous process of vapour depositing metals such as Al, Au, Ag, Cd and Sn on a substrate such as ferrous strip, the strip is continuously fed into a vacuum chamber and the coating metal in solid form, e.g. as a wire. is fed to the upper portion of the vertical face of an upright electrical resistance through which current is passed to melt and vaporize the coating metal.  As shown in Fig. 1, strip 10 is continuously fed via roller 11 into a vacuum chamber which contains a vapour source assembly 14. This assembly comprises an elongated resistor 20, preferably made of boron nitride and titanium diboride or zirconium diboride; the ends of the resistor engaging water cooled copper connectors 23 and 24. The resistor, connectors and insulators 40, 41 are held in position by a spring clamp comprising steel strips 36 and 37 and a screw rod 42.  The coating metal, e.g. Al wires 46, 47, diameter 0.062-0.375 inch, is fed by rollers so that the leading end of the wires continually about the vertical faces of the resistor.  The rate of feed of the wire depends on the current supply which is adjusted to give the required balance.  The coating metal melts, flows down the resistor, vaporizes and forms a coating on the strip which moves past the resistor parallel to the vertical face on which the coating metal is applied.  The strip is turned through 180 degrees by a roller 12 and a further coating is applied from the other vertical face of the resistor. The other face of the strip may also be similarly coated by locating another resistor 50 in the chamber and arranging another roll 13 to change the direction of the strip.

Title: Improvements in or relating to the conversion of ammonium thiocyanate to ammonium sulphate
IPC: C01C1/246
Filed: 1958-12-09
Abstract: Ammonium thiocyanate is converted into ammonium sulphate by adding the thiocyanate, in portions or continuously, to sulphuric acid of at least 20% concentration, at a temperature between 90 and 130 DEG C., in such amount or at such a rate that no free thiocyanate ions are present in the reaction mixture for more than 10 seconds.  The acid concentration is, preferably 78%, and the thiocyanate may be added as the 20-30% lye obtained by scrubbing out hydrogen cyanide from coke oven or similar gases with an ammonium polysulphide solution.  To avoid the reduction of the sulphuric acid concentration, the ammonium thiocyanate may be added as a concentrated solution, slurry, or solid, or fresh sulphuric acid or sulphur trioxide may be added. Carbon oxysulphide, contaminated with HCN and HCNS, is obtained as by-product.  These contaminants may be removed by passing the carbon oxysulphide through the unconverted lye.
Patent GB-1202466-A (GB)
Title: A waveform generator for providing width-modulated square waves
IPC: H02P27/08
Filed: 1968-08-20
Abstract: 1,202,466. Control of A.C. motors. DANFOSS A/S. 20 Aug., 1968 [29 Aug., 1967], No. No. 39716/68. Heading H2J. [Also in Division H3] Crossovers between a constant amplitude, variable frequency waveform R, Fig. 4, and a constant and higher frequency, at least parttriangular, variable slope waveform e are sensed by a comparator (11, Fig. 1, not shown), which triggers a square wave generator to produce a width-modulated waveform g R  suitable for motor control. The variable frequency waveform R is one of the three phase outputs R, S, T of an oscillator (2) each of which outputs is fed through a resistance (7), which may be variable, to a respective comparator (11) which also receives through a resistance 8, also optionally variable, the output e of an oscillator (1) producing the higher frequency waveform. The resulting square waves, g R , g s , g T  are used to control a three-phase motor. A single D.C. signal (B) varies directly the frequency of the wafeforms R, S. T. and varies inversely the slope of the waveform e; and the square waves g R , g s , g T  each have an average value whose magnitude is inversely proportional to the slope of e, and whose frequency of variation is directly proportional to the frequency of the waveforms R, S, T. Thus a motor controlled by the square waves has its speed varied at constant torque by the single control voltage (B). Each comparator 11 may include a subtractor and a high amplification null detector; or it may be a Schmitt trigger. In modifications, the control D.C. (B, Fig. 5, not shown) directly controls the oscillator (2), and inversely controls (at 29) a square wave (from 3c) which is then integrated (at 31) to give the variable slope signal e which is fed as before to the comparators (6). A slope detector (33, Fig. 6, not shown) may he added to this arrangement. Alternatively, the D.C. bias (B, Fig. 7, not shown) may be applied to directly control (at 34) the amplitude of the square waves (from 30) which are again integrated (at 31) and applied to the comparators (b), the slope detector (33) in this case providing the conttol signal (B<SP>1</SP>), inversely proportional to the D.C. control signal (B), for the oscillator (2). The slope detector (Fig. 5, not shown) has a transistor (35) whose base receives the signal e and whose emitter receives the signal e without the square pulses 28 on the peaks. The transistor (35) and a complementary transistor (36) conduct for the period of each pulse (28), the widths of which vary with the slope of the waveform e. The output of the transistor (36) is smoothed and applied to an emitter follower transistor (42) which provides the (B<SP>1</SP>) signal inversely proportional to (B).

Title: Substituted 1:2:3:4-tetrahydro-anthracene-1-ones and process for their manufacture
IPC: C07C233/00
Filed: 1959-11-23
Abstract: The invention comprises compounds of formula:-  <FORM:0914892/IV (b)/1> wherein X is chlorine, R1 is a hydrogen atom or a carboxyl or carboalkoxy group, R2 is a carboxyl or carboalkoxy group and R3 is hydrogen or an alkyl radical containing 1 to 4 carbon atoms.  They are prepared by a process wherein a compound of formula <FORM:0914892/IV (b)/2> wherein X is chlorine, R3 is an alkyl radical containing 1 to 4 carbon atoms and A is a chlorine or bromine atom or an alkoxy group is reduced to replace the -CO-A group by a -CH2OH group, the alcohol is converted into a hydrohalic acid or p-toluene sulphonic acid ester, the ester is condensed with an alkali metal carbethoxy-succinic acid dialkyl ester or an alkali metal carboethoxymethyl-malonic acid dialkyl ester, the compound obtained is partially hydrolysed and then ring-closed using polyphosphoric acid.  If desired any esterified carboxyl groups may be saponified, the resultant dicarboxylic acid may be decarboxylated to give a monocarboxylic acid and any alkoxy group may be treated with acid to form a hydroxy group.  In the example 1-methyl - 2 - carbomethoxy-4:5-dimethoxy-8-chloronaphthalene is reduced with lithium aluminium hydride to 1-methyl-2-hydroxymethyl - 4,5 - dimethoxy-8-chloronaphthalene which is reacted with phosphorus tribromide or p-toluenesulphonyl chloride to give 1-methyl-2-bromomethyl-or -p-tosyloxymethyl-4 : 5 - dimethoxy - 8 - chloronaphthalene.  The bromide or tosylate is reacted with the sodium derivative of carboethoxymethyl-malonic acid di-tert-butyl ester to give the ethyl ester of 2,2 - di - tert.-butoxycarbonyl-3-(1-methyl-4,5-dimethoxy - 8 - chloronaphth-2-yl)-propane-1-carboxylic acid.  This ester is saponified (COOC2H5 group only) with methanolic potassium hydroxide and the acid-ester cyclized with polyphosphoric acid to give 1,2,3,4-tetrahydro - 3,3 - di-tert.-butoxycarbonyl-10-methyl-5-chloro-8, 9-dimethoxy-anthracen-1-one which is saponified to the 3,3-dicarboxylic acid, decarboxylated by heating in diethyl phthalate to the 3-carboxy-compound and finally demethylated by heating in a mixture of glacial acetic and hydrochloric acids to 3-carboxy-5-chloro - 8,9 - dihydroxy - 1,2,3,4 - tetrahydroanthracen-1-one.  A similar series of reactions beginning with 1-methyl-2-bromomethyl-4 : 5-dimethoxy-8-chloronaphthalene and the sodium derivative of carboethoxy-succinic acid diethyl ester is described.  Carboethoxymethyl - malonic acid di-tert.-butyl ester is prepared by condensing sodiomalonic acid di-tert.-butyl ester with ethyl bromoacetate.

Abstract: 1,072,588. Comparing punched tapes. MULLARD Ltd. Dec. 30, 1965 [Sept. 30, 1964], No. 39806/64. Heading G4M. The tapes are advanced by stepping magnets through respective readers A, B each of which comprises a set of contacts, only one of which AO, BO is shown. If the characters being simultaneously sensed by the readers are different, one or more pairs of corresponding contacts such as AO, BO will be in different positions, so that relay RLE is energized from S1 via AO, say, LOA, LOB and BO to earth. The resistance of RLE is made high enough for the energizing current not to be sufficient to cause a noticeable glow in lamps LOA, LOB etc. RLE is used to step the advance of the tapes, and its contact E3, besides completing a holding circuit for RLE, reverses the polarity of the supply rail so that diodes MR3 may conduct and the sets of lamps LOA, LOB are energized to display the two characters at present being sensed. The figure is a simplified version of the system illustrated in Fig. 2 (not shown) in which the tapes may be advanced simultaneously and automatically or individually under manual control.
