Glass-reinforced concrete is applied to each part-mould (2, 3), then allowed to partly dry before the part-moulds (2, 3) are folded together to produce a finished product.

Abstract: A method of locking an established flared or compression fitting by the use of a form consisting of two identical halves shaped and dimensioned freely to accommodate the fitting and adjacent portions of the tubing ends. Supplies of the two components forming, when mixed, a volume of epoxy resin such that if contained within the form when assembled about a fitting, overfills the form. Approximately one half of the resin is poured into each of the two halves which are then assembled about the fitting with excess resin extruded at least through the ends of the form. When the resin is hardened it locks the fitting and the peripheral nut surfaces preventing the loosening of the fitting nuts.

Abstract: A method for manufacture of a plastic credit card includes steps of providing a mold with two shells. When the mold is closed the shells have opposed faces defining a cavity for producing the card. The general outline of the card is defined by the peripheral edges of the mold faces.

Plastic is delivered through a mold face and the inflowing plastic forces the respective image supports against opposite mold faces. After cooling, the mold card, now decorated on two faces, is removed from the mold.

Abstract: A water ski tow line constructed to provide anti-rotation of the tow line handle. The water ski tow line has a handle with holes at each end traversing the handle. A tow line is attached to each end of the handle by passing the line around the handle and through the holes traversing the handle such that two lines are provided extending from tangent points on opposite sides of the handle.

The second coating should have a refractive index substantially identical to diamond, with zinc selenide and titanium dioxide being particularly preferred.

Abstract: A concrete conduit is completely encased within a shell of a plastic resin such as polyethylene. The plastic shell functions to insulate the concrete conduit from mechanical shocks thereby preventing breakage and cracking of the conduit. The shell also effectively provides an impermeable barrier for water vapor and a smooth, relatively frictionless, surface for receiving electric cables, wires and the like. The conduit is made by preforming the shell, for example by rotational molding, and filling the shell with pourable cement through a filler hole in the shell. The filler hole can then be closed with a plug of the resin used to form the shell.
