[Also in Division F2] A laminated material of strip form and suitable for wrapping pipe-lines comprises a fibrous layer capable of resisting longitudinal tension, and thermoplastic layers applied to opposed surfaces of the fibrous layer, the thermoplastic layer on one surface of the fibrous layer being coextensive with the latter and thicker than the thermoplastic layer on the other surface. As shown, a web 14 of non-woven glass fibres, which includes a number of spaced, parallel, continuous, longitudinal glass monofilaments or yarns 15, is drawn from a roll 16 and fed, together with four strips 17 of polyethylene from four coaxial rolls 18, to the nip between a nip roll 20 and a cooling roll 21. A layer 25 of polyethylene, which may contain a pigment, is extruded from a nozzle 24 immediately above the nip and is bonded to the web 14 and cooled by roll 21. The extruded polyethylene impregnates the web 14, some of the impregnating polyethylene welding to the underlying polyethylene strips 17, Fig. 4 (not shown). The laminate is then slit along longitudinal lines 10-13 (Fig. 2) in a unit 28 and the resulting three laminated strips are wound up on spools 29. In a modification, Fig. 3 (not shown), the four polyethylene strips 17 are replaced by a single polyethylene layer (17a), which is coextensive with web 14 and thinner than the polyethylene layer 25. When helically wound on a pipe-line, Fig. 5 (not shown), which has been coated with hot bituminous or coal tar material, each turn of the laminated strip overlaps the edge of the preceding turn, strip 17 or layer (17a) being heat sealed to layer 25 at the overlap.

Abstract: 1,231,103. Alumina-silica coating. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 April, 1968 [28 April, 1967], No. 19683/68. Headings C1A and C1M. [Also in Division H1]  A layer of " aluminium silicate " is provided on a semi-conductor substrate by deposition from a gaseous phase containing an O 2 -containing silicon compound and an organic aluminium compound, on to the heated substrate. " Aluminium silicate " is defined as a stoichiometric or non-stoichiometric mixture of Al 2 O 3  and SiO 2  which may optionally include relatively small quantities of dopants and is a vitreous, crystalline or agglomerate material. Until the surface of the semi-conductor is sealed by a layer of " aluminium silicate " particles the oxygen content of the gaseous phase is kept low enough to prevent oxidation of the semi-conductor substrate and the total oxygen content in the gaseous phase less the oxygen in the O 2 -containing silicon compound is kept low enough to prevent aluminium in the gaseous phase from oxidizing. In the example, GaAs is coated at 400 C. with " aluminium silicate " from a gas mixture of tetraethoxysilane and tri-isobutyl aluminium, with tetramethyl tin being used to provide a dopant. A second coating without dopant may then be added.

[Also in Division E1] A building panel is formed by placing bricks or tiles with their faces directed downwardly, on to a surface, placing resilient spacing means between adjacent bricks or tiles, arranging the spacing means to be compressed when the panel is completely built up to thereby form a seal around each brick or tile, placing a cementitious backing on the bricks or tiles and allowing it to penetrate between them until reaching the spacing means, the backing covering the bricks or tiles to form a monolithic panel. Rows of tiles are laid within a framework of bars 6, 8, 13 and 14 on a table top, Fig. 1, preferably covered with rubber and lengths of sponge or solid rubber is stretched between adjacent rows, the ends of the lengths extending through notches 9 in bars 8 and being knotted at their ends to hold them stretched. A similar material is located between adjacent tiles in a row. When all the tiles are in position the stretched spacer lengths are released and are kept in compression by engagement with the tiles. A cementitious mat is then placed on the backs of the tiles and may comprise a mortar followed by a lightweight concrete; wire loops for fixing the panel may be positioned in the backing at intervals. Opposite ones of the bars 6, 8, 13 and 14 are shaped to provide a tongue along one edge of the panel and a groove along the other, thereby providing interengagement means between similar panels. Temporary wooden or rubber blocks 22 of approximately one half tile length may be located at the ends of alternate rows and eventually removed when the panel is placed against a similar one also having gaps where similar blocks are removed so that full length tiles can be fitted into the adjacent gaps. A further layer of tiles may be located on the back of the cementitious layer. Two tilting tables may be used on each of which a panel is formed, the tables being then tilted to bring the panels vertical and adjacent, whereupon concrete is placed between them.

In a container and valve assembly 12 and 14 respectively, which is designed for use in draining body liquids during surgical operations, flow of the body liquids into the container 12 takes place via tubes 17 and 16 as a result of suction being applied to the container interior via the valve 14 and the tube 3, withdrawal of gas from the container taking place through passages 15 and 4 of the valve 14. Upon the foam or bubbles on the rising surface of the liquid in the container, or the rising liquid surface itself, entering a passage 11 and hence touching a diaphragm 9 of the valve 14, the diaphragm rises to engage an upstanding seat 6 formed at the end of passage 4 and thereafter is retained in engagement with the seat by the suction applied to tube 3. With the above arrangement, and particularly the disposition of passages 11 and 15 relative to the rising liquid surface, the entry of either liquid or foam into suction passage 3 is at all times inhibited. The valve diaphragm 9 is preferably formed of a rubber membrane secured between two annular washers 10. The valve is said to be disposable.

The casing 34 is detachably secured to one end of a shaft 25 which is supported in bearings 26 in a housing 22 and is driven by an electric motor 23. The fluid to be cleaned is supplied to the chamber 36 via a pipe 20, one end of a stationary cylinder 28, radial bores 40, the bore of a hollow portion 27 of the shaft 25 and radial bores 43. The cleaned fluid is discharged via the vane assembly 30, the cylinder 28 and a pipe 33. The cylinder 28 is rigidly secured to a radial wall 29 in the housing 22. Seals are provided at 41, 42. The casing is cleaned of accumulated solid particles by removing the housing cover 19 after releasing a bayonet coupling 44, unscrewing a screw 37 and releasing pivotable clips 38. In a modification, Fig. 3, the fluid to be cleaned is supplied to the interior of the separator casing 52 via an inlet 55 and an annular passage between a solid shaft 51 and a stationary tubular member 56. The cleaned fluid is discharged via a vane assembly 59, a passage between tubular members 56 and 57 and an outlet 58.
