  • Patent number: 6015050
    Abstract: A modular storage system utilizes pluralities of mutually orthogonal members removably coupled to one another through cooperative male and female connectors to form a lattice structure with a plurality of receptacles for storing articles such as compact disc (CD) jewel boxes and the like. First members include female connectors having at least one aperture through which are coupled a pair of coaxially-oriented second members extending orthogonal thereto. One of the second members includes a pin which is hollowed out to define an aperture suited for receiving the pin of the other second member such that both second members are coupled to one another as well as to the first member. In addition, the female connectors in the first members include a pair of apertures, with male connectors of the second members including pairs of pins suitable for engaging the apertures in the first members.

  • Patent number: 5375293
    Abstract: A retrieval and collection device is adapted for removable coupling in-line to a conventional portable vacuum cleaning system, at an upstream end of a vacuum hose. The retrieval device includes a casing with a relatively large diameter medial region and respective upstream and downstream coupling sleeves at opposite ends of the casing. The casing consists of two casing sections joined along the casing medial region for periodic disassembly to remove captured articles. The size of articles to be captured is determined by a flat, disc-like screen removably mounted in a chamber defined by the casing medial region. Multiple apertures through the screen are substantially uniform in size to capture objects of at least a given dimension. Separate screens with apertures of different sizes can be interchangeably mounted in the chamber. Each screen is part of a partition device that further includes a collar surrounding the screen and a handle projected axially from the center of the screen.
