  • Patent number: 11751731
    Abstract: A stabilized toilet seat and toilet bowl that operates to prevent the toilet seat, when placed in a parallel orientation relative to the rim of a toilet bowl, from moving laterally or diagonally. The stabilized toilet seat and toilet bowl includes an interlocking system integral with both the toilet seat and the toilet bowl which automatically engages whenever the toilet seat is hinged into the parallel orientation without placing any restriction on the toilet seat's hinging movement into or out of the parallel orientation. A locking protrusion integral with the toilet seat and a locking slot integral with the toilet bowl may form the interlocking system.

  • Patent number: 5133441
    Abstract: An electronically controlled dispensing machine for articles such as video cassettes has a plurality of individual lockable compartments. The compartments have transparent doors through which the articles can be identified. A customer presents a coded data storage token with a credit amount stored on it to the machine, and selects and removes one or more articles. The machine reduces the credit amount on the token accordingly. The articles can be returned to a vacant compartment in due course, and if the article is returned late, a further amount is deducted from the credit amount on the token. Sensors in each compartment ensure that the cassettes are inserted correctly by sensing an electrically conductive portion of the cassettes.
