Abstract: 1298008 Cross-linking monomers for unsaturated polyesters STAUFFER CHEMICAL CO 19 May 1970 [28 May 1969] 24093/70 Heading C3P [Also in Division C2] The invention comprises a polymerizable composition comprising an ethylenically unsaturated polyester and cross-linking compounds wherein at least a portion of the cross-linking compounds are novel vinyl polyphosphonates of the formula wherein n is a number of at least 2, e.g. up to 20 and preferably between 2 and 6. When polymerized the composition provides a fire retardant insoluble thermosetting resin. Useful ethylenically unsaturated polyesters are those derived from the polycondensation of dihydroxy or polyhydroxy aliphatic compounds and dicarboxylic acids or anhydrides at least a portion of which are ethylenically unsaturated dicarboxylic acids or anhydrides. The latter acids and anhydrides may be used in admixture with saturated aliphatic or aromatic dicarboxylie acids or anhydrides in the preparation of the polyesters. Alkyd resins which have been modified by the inclusion of unsaturated fatty acids or rosin acids and which contain olefinic unsatura - tion may also be used. The flame retardant properties of the polymerized product is also enhanced if the polyester contains organicallybound Cl or Br atoms which may be present either in the dicarboxylic acid or anhydride or in the diol used. The cross-linking compounds I may be used in admixture with a variety of other vinyl compounds especially vinyl esters of aliphatic acids having up to 6 carbon atoms, vinyl aromatic compounds which may contain Cl or Br, acrylic and methacrylic esters, and acrylonitrile type derivatives. The polymerizable composition is cross-linked by the use of a free radical initiator, e.g. U.V. radiation especially with the addition of a photosensitizer such as benzoin; an azo compound; or a per compound including per oxides, per acids and per esters. Fillers and pigments and also some antimony oxide may also be included. In a comparative example an ester of Formula I in which n is 2À5 is polymerized per se.

Abstract: 1342157 Super-conductors IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 20 Sept 1972 [4 Oct 1971] 46053/71 Headings H1A A5 A4B and A4D A method of manufacturing a super-conductor comprising an intermetallic compound of at least two elements includes the steps of providing a composite precursor of at least one filament of at least one of said elements supported in a matrix material, passing the precursor through a liquid or vapour containing the remainder of said elements to remove at least part of the support material and replace it with a substance comprising the remaining elements, and reacting the elements to produce the compound. In a first embodiment a composite precursor comprising a plurality of filaments of Nb embedded in a Cu support is produced by extrusion and drawing and passed through a bath of molten Sn which dissolves the Cu. As the filaments are withdrawn from the bath they are coated with Sn which solidifies to form a matrix. The Sn may react with the Nb to form Nb 3 Sn coatings on the Nb filaments in the bath or in a second, hotter bath, or in an inert atmosphere. A low temperature initial bath may remove the Cu and produce the compound Nb 3 Sn 5  (which is non super-conductive) which is converted at least in part, to Nb 3 Sn in a hotter bath. The structure may be stabilized by using as filaments Nb tubes filled with Cu, Al or Ag or an alloy, or by coating or plating the reacted composite with Cu, Al, or Ag. A bronze may be used instead of Sn and the compound may comprise a surface layer or a solid filament. The original support may also be of Al, Ni or Ag and if Ag is used it may be hardened by alloying with Cu, Pb, In or Al. The super-conductive compound may be Nb 3 Al or Nb 3  (Al-Ge) produced by using Nb filaments and baths Al and Al-Ge respectively or may be V 3 Si produced by using V filaments and a bath of Si or an alloy, e.g. of Cu-Si. The compounds Nb 3 Ga and V3Ga may also be produced. Steel filaments may be included in the original structure to increase the strength of the final composite. The filaments may be transposed (twisted) in the original structure, the final composite having the same form.

Abstract: 1352959 Semi-conductor-glass seals; glass composition STANDARD TELEPHONES & CABLES Ltd 9 Nov 1972 51659/72 Heading C1M [Also in Division H1] The lateral edges of semi-conductor mesas 46 on a wafer 41 are passivated by positioning an assembly of equally spaced parallel glass fibres 14 so that each fibre occupies one of the grooves between the mesas, and softening the glass so that it flows and fills the grooves. If necessary the process can be repeated with the wafer rotated through a right-angle so that each mesas 46 is entirely surrounded by glass. Optionally the back of the wafer 41 may subsequently be entirely removed by use of a polishing pad impregnated with an etchant, leaving only the mesa portions 46 embedded in a glass matrix. Where shallow mesas are required to be passivated the process of softening of glass fibres is first carried out to fill relatively deep grooves, following which shallower secondary grooves are etched between the mesas and the glass and the latter is reheated so that it flows into the secondary grooves and into contact with the mesas. For GaAs a suitable glass composition is PbO 69%; Al 2 O 3  14%; B 2 O 3  11%; SiO 2  6% (wt. per cents). An apparatus connecting the fibres together in a parallel assembly and spring-loaded apparatus for maintaining the fibres under constant tension during the softening process are also described, Semi-conductor lasers, Gunn diodes and IMPATT diodes are referred to.

Abstract: 1354624 Brushless motor supply circuits; control of stepping motors ULTRA ELECTRONICS Ltd 15 March 1972 12025/72 Headings H2A and H2J [Also in Divisions H3-H5] In a stepper motor circuit, the electrical excitation of adjacent poles is so modulated that in the desired position of the rotor between the two poles the torque falls to zero. The output of oscillator X14, X15 operating at 30 KC/S is fed to the winding 42 of the central limb of a core having three spaced limbs 43, 44, 45 (as in Fig. 1, not shown) and a semicircular ferromagnetic coupling member 40 is rotated above them by drive motor 20, the motor also driving wiper 30 over potentiometer 31. Out-of-phase signals from the oscillator are used to switch transistors X1, X2 the effectiveness of either or both being determined by potentials at 52, 53 controlling further switching transistors X3, X4. Assuming the motor rotor to be well away from its desired position, then the rotors of motor driven potentiometer 31 and externally variable potentiometer 34 are so widely spaced that the output at terminal 39 causes the mark/space ratio circuit (Fig. 3, see Divisions H3-H5) to give a full output on, say terminal 52 so that transistor X3 conducts, causing energization of transistors X5, X6, X7 in accordance with the drive signals from windings 43, 44 and 45. The outputs from these transistors cause capacitors C3, C4 and C5 to charge, as appropriate and the charged capacitors maintain one or two of the transistors X8, X9 and X10 in conduction during the whole cycle of the output from the oscillator. As a result, the appropriate power amplifiers X11 ... X13<SP>1</SP> are energized and the stepping motor rotates in the corresponding direction. As the rotor approaches the desired position, movement of slider 30 causes the input to the mark/ space circuit to change and ultimately output also occurs alternately on terminal 53, during which time output on 52 is suppressed. Due to the transistor X4 switching on during this period, reverse torque is applied to the rotor so that the net forward torque falls until ultimately at the required position, it reaches zero.
