Abstract: A method for producing a composite bathtub having at least one steel shell and at least one acrylic shell which are solidly joined to each other. A deep-drawn acrylic blank is first reverse-drawn over a core. An outer shell mold is then placed over the acrylic blank, at a certain distance from the acrylic blank. Once the outer shell mold and the acrylic blank are sealed off from each other, a reaction resin is injected into the space between the two shells. After the reaction resin has set, the outer shell mold is removed and the steel blank is positioned. The space between the steel blank and the acrylic blank is re-sealed and a polymer foam is injected into this intermediate space. Once the polymer foam has cross-linked, the composite bathtub is complete. One advantage of the method of this invention is that the acrylic shell and the steel exterior of the composite bathtub do not have to be identical in shape.

Abstract: A multi-packaging device capable of carrying containers having a range of diameters. The multi-packaging device is constructed from a plastic sheet having an array of apertures arranged in lateral rows and longitudinal ranks. The plastic sheet contains integral segments of a resilient polymer coextruded with respect to the plastic sheet or laminated on the plastic sheet. The plastic sheet may also contain a longitudinally arranged line of weakness under the resilient polymer. The resultant structure enables the multi-packaging device to maintain integrity when a large diameter container is inserted into an aperture because the resilient polymer laminate continues to stretch even after the plastic sheet reaches a stress level approaching neck-down.

Abstract: A communications system that uses electromagnetic waves. The communications system preferably operates in the millimeter-wave frequencies, and provides relatively high signal restoration and isolation. The communications system can use polarization diversity to increase the capacity of a channel. Isolation and restoration features in the transceivers eliminate or reduce the effects of precipitation and/or reflection and diffraction from objects, and thus is well-suited for an urban environment. The transceiver will select the proper antenna and signal path for optimal information throughput as the conditions in the propagation medium of the network vary.
