As shown in Fig. 1 a dowel 59 has a central bore 61 and radial apertures 65 through which adhesive passes to secure the dowel in a hole 63. The adhesive constituents are ejected from a tool 64 and are mixed in a detachable mixing chamber 60. In another embodiment, Fig. 3, the fastening element is a pipe support having recesses 75, 77 for receiving adhesive to fasten the support to a foundation and a pipe 78 respectively; there is a detachable mixing chamber 74. The mixing chamber for either embodiment may be made of plastics and have a labyrinth channel or a frusto-conical body 74, Fig. 5, and rotatable screw 79 which may be rotated by the ejector tool (see Figs. 8-12, not shown). The tool may contain the adhesive constituents in flexible cartridges having cross-sections proportioned to the desired ratio of the constituents in the adhesive (see Figs. 6 and 7, not shown).

Abstract: 1,040,400. PN Junction devices. STANDARD TELEPHONES & CABLES Ltd. Nov. 27, 1963, No. 46849/63. Heading H1K. A PN junction device is produced by forming a layer of one conductivity type on a plane face of an insulating or intrinsic semi-conductor substrate, forming a second plane face at an angle to the first and producing a layer of the opposite conductivity type thereon, one face of which forms a PN junction with the edge of the first layer. In the embodiment the substrate is a cylindrical body of intrinsic gallium arsenide and the layers are formed by impurity diffusion or epitaxial deposition. At least the first layer, which is formed on a (100) face of the substrate, is masked during production of the second layer. The second face is produced by cleavage along a (110) plane. Individual elements for use as lasers are divided from the resulting body by cleavage along parallel 110 planes perpendicular to the second face.

Abstract: 1,011,350. Retreading moulds. PAUL E. HAWKINSON CO. Dec. 2, 1963, No. 47551/63. Heading B5A. A mould for use in retreading tyres comprises an outer cylindrical mould element 1, of sheet steel, having flanges 3 between which a metallic heating coil 6 is spirally wound. A metal tread forming matrix of, e.g. aluminium comprising a series of abutting segments 5 is contained within the outer mould element, each segment carrying a groove 11 in each of its flanges 9 to define a pair of continuous channels 12. A metallic heating conduit 13 is located in the channels and retained therein by peening the flanges 9 at suitable points, e.g. 17, the outlet 15<SP>1</SP> of the conduit in one flange being connected to the inlet 14<SP>1</SP> of the conduit in the other flange so as to allow heating by one circulating stream of water.

Abstract: 1,071,778. Reinforced resin articles. UNIVERSAL MOULDED FIBER GLASS CORP. Dec. 4, 1963 [Dec. 11, 1962], No. 47912/63. Heading B5A. In a method of making fibre-reinforced solidified resin articles, at least one resinimpregnated reinforcement layer, e.g. 20, 21, and at least one parting strip 22 are introduced into the forming passage of a heated forming die 17, the solidified article being pulled from the die, e.g. by puller mechanism 19 and the parting strip and reinforcement being separated from each other after the solidified article has been removed from the die. As shown in Fig. 1a resin-impregnated reinforcement layers (e.g. glass fibres) 20, 21 and a parting strip 22 are directed through a pan 18 containing liquid resin, e.g. a polyester resin containing a hardener such as benzol peroxide, to the forming device 17. The parting strip may be of width slightly less than the width of the forming passage so that the resin material flows around the edge of the parting strip to inter-connect the upper and lower articles (20a, 21a) which are slit apart by slitting knives (24) (Figs. 8, 9, not shown) as the sandwich is drawn from the discharge end of the forming device by puller mechanism 19. Guide devices (25, 26, 27) (Fig. 1b not shown) are provided to separate the formed articles from the parting strip, roller type support tables (28), (29) being provided for the articles (20a, 21a), and cut-off discs (30, 31) being provided to cut off desired lengths of the material. The parting strip is then fed to a cleaning station (34) and is returned to the input side of the system. Alternatively the parting strip may be fed from a roller and collected on a wind-up reel after it has been separated from the articles. The parting strip may be a thin flexible steel strip or be made of a resin material. The number of articles produced may be varied by increasing the number of parting strips. Also a single reinforcing layer and a single parting strip may be used. To form very thin articles the layer of impregnated fibre reinforcement is fed through the forming die between two parting strips. As seen in Fig. 11 (not shown) parting strips (55) in addition to the main parting strip may be used to form grooves in the articles. The parting strips may be smooth or textured and in addition may be provided with transverse ribs or grooves to provide complementary surfaces on the finished articles.
