Abstract: A cabinet having a lower door which opens outwardly and an upper door which opens downwardly to rest on the opened lower door; thereby the cabinet may be converted into a bar. The lower door preferably has an extension hinged to its outer end which folds outwardly and the upper door is preferably right angularly shaped to overlie the extension when it is folded open.
Abstract: An endless track belt adapted for use on all types of track laying vehicles. The track is constructed to have the capability of utilizing ground material coherence as a primary means of flotation. In the exemplary form, the track is in the form of a grid having longitudinal tension elements, transverse elements preferably fabricated from elastomeric materials, but not limited thereto. It has the characteristic of inherent low mass-to-floatation surface area ratio and to be operable at a high velocity. The grid is an open network, minimizing total quantitative belt section relative to ground area encompassed. The grid has lateral flexiblity allowing for lateral displacement or deviation into a curved configuration for steering.
Abstract: Porous, tubular core sections coated with a semipermeable membrane are joined at their ends by a simplified coupling member. Each coupling member or connector comprises a cylindrical flange member having circularly barbed or serrated nipples which fit tightly into the ends of bores of adjacent core sections. The ends of the cores abut against the circular part of the coupling member. Surrounding the joint thus formed is a flexible, elastomeric sealing sleeve. The nipples on the coupling member are axially slotted and have neck parts of a smaller diameter adjacent the body part of the coupling member providing annular openings between these neck parts and the bores of core members permitting continuous flow of permeate and cleaning solution without there being appendages, cavities, or pockets in which permeate or cleaning solution could be trapped.
