Filed: 1969-05-01
Abstract: 1,241,236. Polysiloxane coatings. OWENSILLINOIS Inc. I May, 1969, No. 22260/69. Heading B2E. [Also in Division C3] A plastics substrate is provided with a hard, heat and acetone resistant organopolysiloxane coating by reacting a silane, which is methyltrialkoxysilane e.g. CH 3 Si(OC 2 H 5 ) 3  or a mixture thereof with phenyltrialkoxysilane e.g. CHH 5 Si(OC 2 H 5 ) 3  in which the alkoxy group contains less than 5 C atoms, with water at 50-80‹C for 1-10 hours, heating to 80- 300‹C to remove alkanol and water and then precuring at 90-140‹C to form a precured, further curable polysiloxane which is then dissolved in an organic solvent. The solution, which preferably contains 5-85 wt % polysiloxane is applied to the substrate e.g. by spraying, brushing, rollers or dipping. The solvent is evaporated and the coating is cured by heating at 90-140‹C for 4-168 hours. The coating compositions may contain UV absorbers e.g. 2-hydroxy-4 methoxy benzophenone, which is preferably present in an amount of 1-5% wt, as well as fillers, pigments, antioxidants, stabilisers, antistatic and antifoaming agents. Up to 10 mole % of diphenylsilanediol may be present with the silane and when a silane mixture is employed the molar ratio may vary between 10:1 and 1:10. A wide variety of suitable substrates and organic solvents are specified.

[Also in Group VIII] A process for producing accurately co-operating pin-and-pin-hole rollers of a perforating mechanism is characterized in that holes at the required pitch division for the pins and pin holes of the pin roller and the pin-hole roller are formed in each case in a flexible metal band, consisting of one or more pieces, or a hollow cylindrical metal shell, consisting of one or more pieces, separate from the rollers. before the application of the metal band or shell on a roller, the metal bands or shells then being arranged opposite one another on the rollers in such a way that pins inserted in the holes of one roller co-operate accurately with the holes of the other roller, after which the metal bands or shells are fixed in the adjusted position on their rollers. When metal bands are used, these are preferably provided with holes at the required pitch division while in a plane position, and are then each laid round a base body of a roller acting as a pin roller or a pin-hole roller. The band on the pin roller is fixed in position and is then used as a template for the production of bores in the base body to provide a mounting for the pins of the pin roller. When metal shells are used, the holes are formed by drilling. As shown, hollow metal shells 41, 42 to be drilled with holes longitudinally and circumferentially thereof are mounted on a shaft 36, in turn mounted on a table 28 which is movable parallel to the shaft 36. The movement of the table 28 and the circumferential movement of the shaft 36 about its axis, are determined by perforated indexing bands 30, 44, provided respectively on the table and on a disc 43 mounted on the shaft and co-operable with index pins 33, 46 on fixed holders 32, 45 respectively.

Abstract: 387,719. Storing fuel on aircraft. DUNCANSON, F., Merecoombe, Gothering- ton, Gloucestershire. Aug. 13, 1931, No. 22879. Addition to 326,870, [Class 4, Aeronautics]. [Class 4.] The tapered tubular spar of the parent Specification is adapted to act as a liquid storage chamber being rendered fuel-tight over the whole or a portion of its span and provided with filling and draw-off apertures. Fig. 3 shows the spar 17 provided with transverse bulkheads 18 which with the central portion of the spar form a fuel tank 180. Perforated baffle plates 19 restrict the movement of the liquid. When the full length of the spar is employed it is subdivided by numerous baffle plates which may be of the type shown in Fig. 14 or Fig. 16, that of Fig. 14 comprising an annular U-shaped frame 119 such as described in the parent Specification to which is detachably secured a wire gauze or chamois leather baffle 190. When the spar is formed of a central parallel portion athwart the body and joined to tapering portions in the wings the central portion only may be used as a tank. Alternatively the tank portions may be arranged on one or both sides of the body and exterior thereto. Applications to twin-engined machines are shown in which the parts of the spar adjacent the engine are used as fuel containers. In cases where the engines are mounted on the level of the wings as shown in Fig. 9, the top half of the spar only is used as a fuel container, a bulkhead 21, Fig. 10, being provided approximately midway of the spar depth, which bulkhead may be provided with tapering channel portions 210 for stiffening and for improving drainage. The portions of the spar below the horizontal bulkhead may also be employed for fuel storage. Oil tanks 30, Figs. 10 and 12, may be fitted adjacent the tanks 180 and may be provided with surface oil coolers 31 on the top or bottom surface of the spar being arranged to project forwardly of the wing into the air stream. The metal plates forming the spar tube at the tank portion will be close riveted at their seams and a jointing material or fluid will be applied to the contacting surfaces or the seams may be rendered fluidtight by soldering, brazing or welding. Vertical longitudinal partitions may be fitted. Apertures or manholes 40, Fig. 3, with detachable covers may be provided on the spar. The outermost bulkheads 18 and any division plates intermediate the inner bulkhead and the outer ends may be made weaker than the spar itself so that distortion of the spar due to accident will cause them to rupture and permit the contained fuel to flow toward the wing tips.
