Abstract: 1,171,012. Coated products. DE SOTO Inc. 10 Feb., 1967, No. 6437/67. Heading B2K. [Also in Division C3] Substrates, e.g. of sheet for automotive finishes, are coated with a thermosetting composition comprising an organic solvent in which is dissolved: (I) A non-gelled condensate of a copolymer of from 3-30% (of the weight of the copolymer) of an ethylenically unsaturated monomer carrying a hydroxyl group, the remainder being at least one monomer containing the CH 2 =C< group, with a Si-containing material having an average of at least 1.2 Si-bonded OH or alkoxy radicals per molecule. The equivalent ratio of Si-OH or Sialkoxy radicals to hydroxy groups in the copolymer ranges from 1:4 to 4:1. Condensation is continued to eliminate 5-95 % of the water or alcohol of reaction and to cause the bulk of the material to become chemically combined with the copolymer. The condensate obtained contains unreacted essentially neutral hydroxyl groups in the copolymer and unreacted acidic Si-OH or Si-alkoxy groups carried by the residue of the Si-containing material in the condensate. (II) an aminoplast resin providing basic methylol groups. The total resin in the composition may comprises 40- 95% by weight of I and 60-5% by weight of II. Suitable OH- containing monomers useful in preparing the copolymer of I are hydroxyalkyl (meth)acrylates, (meth)allyl ethers of polyhydric alcohols, (meth)allyl alcohol, 2-hydroxymethyl-5-nor bornene or an unsaturated fatty alcohol derived from a drying oil fatty acid. The siloxane may have the average general formula: in which R is a monovalent hydrocarbon radical, R' is a hydroxyl or alkoxy radical, n has an average value of 1 to 2, m has an average value of at least 0.1 and m+n is not greater than 3, there being at least 1.2 (preferably 2 to 8) R' radicals per siloxane molecule. Examples of suitable aminoplasts are triazine 1 formaldehyde resins. The solvent (e.g. xylene and butanol) may comprises 30-65% by weight of the composition. Conventional pigments, e.g. TiO 2  may also be present. The coatings may be hardened by stoving e.g. for 15 minutes at 350‹F.

Abstract: 453,124. Cables. STANDARD TELEPHONES & CABLES, Ltd., BAGULEY, E., and LONG, A. L., Connaught House, Aldwych, London. March 1, 1935, No. 6532. Drawings to Specification. [Class 36] A multi-conductor telephone cable for carrier current working comprises two or more layers of twisted cores (pairs, quads, &c.) enclosed in a lead sheath which is spaced radially from the cores by means of a layer of dielectric material of a thickness greater than would be necessary for mechanical or electrical breakdown requirements, the thickness of such layer being critically determined so that the transmission characteristics at carrier frequencies of the cores nearest the lead sheath are substantiaily the same as those of the cores in the centre or inner layers of the cable lay-up, whereby the unequal influence of the lead sheath upon the cores at carrier frequencies is reduced. A thin conducting layer of metal tape or metallized paper may be interposed at a critically determined position in the space between the cores and sheath such that the mutual capacities of the outer layer cores are made substantially the same as those of the centre and inner layers without substantially affecting the previously equalized A.C. resistances of said cores ; the control of the mutual capacities may be effected by varying the overlap or position or both of the conducting layer with respect to the cores ; such layer may be positioned immediately over the outermost core layer.

Title: Apparatus for measuring visibility in a fluid
IPC: G01W1/14
Filed: 1973-02-09
Abstract: 1400311 Measuring visibility photoelectrically IMPULSPHYSIK GmbH 9 Feb 1973 [25 Feb 1972] 6541/73 Heading G1A The visibility in a fluid, e.g. air or water, is determined using a light source 1 and a detector 8 each covered by a respective omni-directional light diffusing plate 3, 7, a baffle device 11 being interposed between the source and detector to prevent direct incidence of emitted light on the detector. The light source may be a laser diode of gallium arsenide, a luminescent diode, an incandescent lamp or a spark discharge lamp and the detector is a photo-diode. The covers 3, 7 may be of ground-glass, or matte boron silicate glass in which is embedded heavy metal ions. This prevents the growth of algae when the device is used in water. It is also possible to vapour-deposit a grid of heavy metal on the plates in which case the plates are matte within their internal structure. The baffle element is heated either by heating elements 12 or by a heating element or elements in thermal conductive relationship with the baffle element. The free edge of the baffle element may be coated with a water-repellant coating, e.g. a synthetic plastic or silicane basis. To prevent formation of algae in water, the baffle element has at least its free edges made of or coated with a heavy metal, e.g. copper. As shown in Fig. 1 the elements are embedded in a potting material 16, e.g. synthetic plastic resin, and the emitted light reaches the detector by forward scattering in the fluid 5. As shown in Fig. 3, the baffle element 11 is circular and is mounted on a frame 19 with the source and detector. The baffle element is heated by transistors 17 and its temperature is maintained constant using temperature detectors 18. A filter 7a is interposed between the plate 7 and detector 8. The battery 14 is charged by a photo-cell 20 receiving ambient light. In an alternative embodiment, Fig. 2 (not shown), the emitted light reaches the detector by back-scattering in the fluid. The detector 8 is connected to an amplifier 9 and a discriminator 10 which provides an output to energize a signalling device when the signals received indicate a visibility less than a pre-set value.

Abstract: 820,798. Winding toroidal coils. MICAFIL Ltd. March 2, 1956 [March 8, 1955], No. 6610/56. Class 83 (4). A device for winding wire on an annular body 17 comprises a wire supply magazine holder 23 mounted on a rotatable member 10 adapted to receive the annular body so that the axis of rotation of the member is a tangent to the means circumference of the annular body, an adjustable tension control mechanism to maintain wire tension independently of the supply on the magazine, and wire guiding means for maintaining the plane of revolution of the wire about the body, the winding device being angularly movable for locating the member relatively to the mean circumference of an annular body and for moving it away from the mean circumference. As shown, a gear-wheel 5 on a driven axle drives through intermediate gears 7, 8, 9 a pinion 10 supported by a hardened guidemember 11, the support plate, pinion 10 and guide 11 being apertured to afford entry of the annular body 17, a closure 13 controlled by a lever 12 closing the aperture for insertion of the body. The magazine 23 of wire is mounted on a brake drum 22 on an axle 18 secured to the pinion 10 and relative rotation prevented by a pin 24. A brake wire embraces the drum 22 over an angle of 300 degrees and is tensioned by a spring 29 controlled by an adjusting lever 32 and screw 34. Wire from the magazine 23 passes on to the annular body by way of a guide 20. While the body is being wrapped with wire a reserve magazine 23 on the axle driving the pinion 5 may be filled with wire. The winding device can be swung up to facilitate insertion and removal of the annular body 17, a stop 16 indicating the operative position of the device. The wire tension is controlled by the brake drum 22, the unwinding wire producing a torque opposite in direction to that of a spring 30 on the lever 19 on which the guide 20 is mounted. The resultant of these torques either releases or tightens the spring 29 and hence decreases or increases the braking of the drum 22.
