Abstract: A method of manufacturing a composite insert includes forming a polymer mold from a polymer sheet which may have a glass transition temperature of 70 to 160° C., the polymer mold either includes a cavity or may form a cavity disposed between the polymer mold and the carrier. The method proceeds by depositing a liquid reactive composite insert composition, which may be a two-component composition including a first part comprised of an isocyanate-epoxy blend and a second part comprised of an alcohol-epoxy blend, into the cavity under low pressure conditions of 0-10 bar and low temperature conditions of 15-100° C. The composition is then allowed to become dimensionally stable either within the polymer mold or between the polymer mold and the carrier.

Abstract: A dual inlet and dual outlet valve controls a flow from dual inlet pipes through dual outlets to dual outlet pipes to increase flow where space is not available for a single larger diameter pipe. The valve includes a rotatable cylindrical plug with vertically spaced apart plug mouths. The plug may be rotated to align the plug mouths with one of both dual outlets to allow a flow to the dual outlet pipes, or the plug may be rotated to block the flow to both outlets. The dual inlet and dual outlet valve is particularly useful in a spa where narrow spa walls limit pipe sizes. The valve allows parallel pipes into the valve and from the valve to jets, thus increasing the water flow to the jets and the resulting turbulence.

Abstract: A tub and shower surround assembly is initially molded as a single molded component having a waste strip which separates each individual tub and shower surround portion. The waste strip readily protects the mold and simplifies post molding operations and assures that each portion will meet final tolerances. Another waste strip is located between the tub portion and the wall portions to provide for positive draft between a tub flange which extends about the tub portion and the wall portions. Positive draft is required to assure proper removal of the mold component from the mold. The single component provides for finishing operations to be performed prior to separating the individual components. Since the majority of finishing operations are performed simultaneously prior to separating the portions, the likelihood of damage to the portions are reduced and the finish of the individual portions are of greater consistency.

Abstract: An overflow system suitable for use in controlling the level of water in, for example, a bathtub (3) is described. The overflow system comprises a conduit attached to the overflow outlet (21) of the bathtub (3) and is arranged so that when the bathtub (3) is overfilled, any excessive flow rate of overflow water through the conduit (19) is detected. The excessive flow rate is detected by arranging for the outlet (25) of the conduit to have a smaller maximum flow rate than the inlet (23) of the conduit so that water backs up within the conduit during an excessive flow rate condition. The backed up water may be detected by a reed switch (31) in conjunction with a magnetic float (27) in order to actuate a solenoid valve (9) to prevent any more water from entering the bathtub (3).

Abstract: A device consisting of a combination of a bathtub (1) with a shower tray (3), in which the bathtub (1), when in position B=Bathing, is positioned over shower tray (3) in such a way that its water outlet ends up over the shower tray (3), whilst when in the other possible position S=Showering, it stands upright, i.e. end over end, on one of its ends, thereby freeing access to shower tray (3). Bathtub (1) can easily be manoeuvred from one position to the other by a lifting mechanism and the application of force, preferably generated by an electric motor (13). By completely separating the bathtub from the shower tray and by positioning the bathtub over the shower tray, the edge of the shower tray is on the one hand kept as low as it would be if there were indeed a separate shower tray, whilst on the other hand, the edge of the bathtub is only slightly raised. As a result, both parts are extremely user-friendly, especially for elderly or handicapped persons.
