Abstract: Cubipods are heavy concrete objects used as protection means for dyke or breakwater mantles on coasts or the like and have a cubic or orthohedral shape with projections on the faces (3) thereof; the number, position and geometric shape of said projections (2) may vary. The mold comprises a table (4) with a plate (6) wherein is hollowed a recess (5) corresponding with the lower projection of the cubipod (1) and has support legs (9) on a rigid plinth (10). A prismatic casing (11) with the cubipod (1) shape but lacking the upper base, rests on the table (4). A frame of profiles (18, 19) with a hood (17) for forming the upper projection is hinged on an upper edge. Mould removal is achieved by raising the casing (11), after taking away a number of dihedral surfaces (14-15) which form the lower face of the projections (2) and lower part of the casing.

Abstract: A process and apparatus for manufacturing fiberglass-reinforced panels are provided. The apparatus includes a guide mechanism and drive mechanism to drive individual elongate molds through a gel coating spraying section and thereafter through an oven to cure the gel coat. The elongate molds are thereafter driven through first and second resin/fiberglass application stations to apply a composite of resin and fiberglass strands. The apparatus also includes a station whereby wooden boards may be placed over the top of the resin and the fiberglass strands, and thereafter to a vacuum station whereby a vacuum can be placed over the wooden boards, such that when a vacuum is drawn on the composite, the resin is drawn into the wooden boards to form an integrated deposit panel.

Abstract: Composite polymeric articles, which may be in layer or film form, comprise a larger portion of a polymer which is water soluble at 20.degree. C. against a smaller proportion of a polymer which is substantially water-insoluble at that temperature. For example, a layer product may have a thin layer (e.g. less than 5 microns) of insoluble polymer superimposed on a thicker layer (e.g. at least 20 microns) of soluble polymer. Both polymers are conveniently polyvinyl alcohol, which is non-toxic and useful in a number of domestic applications, e.g. as a diaper backing sheet. The insoluble portion gives water resistance but negligible mechanical strength; the soluble part gives the mechanical strength. On dissolution of the soluble portion, the insoluble portion disintegrates mechanically. Articles may be made by co-extrusion or by molding.

Abstract: An apparatus for making a plastic filament web has in a vertical stack starting from the top an extruder releasably mounted on a platform, connected to a spinneret, and supplying molten plastic thereto for formation of plastic streams, a blowing unit directly beneath the spinneret cooling the streams and forming them into plastic filaments, a stretching gap directly beneath the blowing unit stretching the plastic filaments, a diffuser shaft directly beneath the stretching gap looping the stretched plastic filaments, and a foraminous conveyor directly beneath the diffuser shape receiving the looped and stretched filaments as a fleece which it transports horizontally out of the apparatus. A lowermost housing containing the conveyor sits directly on a stationary support surface and has an upper surface. An uppermost housing spaced above the lowermost housing supporting the extruder platform contains at least the spinneret and has a lower surface.

Abstract: An interposed layer of amorphous carbon promotes the adhesion between conductive substrates and electrochemically deposited polymers. Such a carbon layer may be deposited directly onto the conductive substrate by conventional methods such as, for example, chemical vapor deposition. The subsequently applied electrochemically deposited polymer adheres more tenaciously to the amorphous carbon coating than if it had been electrodeposited directly onto the conductive substrate.

Abstract: Preparation of precast concrete slabs on a casting bed is facilitated through the use of a lay-out cart which moves along over the bed on wheels which engage parallel rails on opposite sides of the casting bed. Production hardware for a days casting can be loaded on the cart and positioned at the proper longitudinal and transverse positions on the bed by workmen riding on the cart and placing the hardware on the bed through an access opening formed through the cart. The access opening is preferably at least as wide as the bed to provide access to the bed across its entire width, and a fixed scale and movable indicator are associated with the access opening to locate specific positions transversely of the bed. A longitudinal scale extends the length of the bed and the cart carries an indicator which is movable along the longitudinal scale to locate positions along the length of the bed.
