Abstract: A storage unit includes frame pieces that attach to a support structure. A first rail assembly has first rails disposed on the frame pieces so that facing channels define a storage region. A drawer is positioned in the storage region when in a stored state. A second rail assembly includes second rails each having a second channel. The second channels receive first wheels that are on the first rail assembly while the first channels receive second wheels that are disposed on the second rail assembly. The drawer may be advanced out of the stored state to an extended state and then into a pivoted state wherein it is perpendicular to the stored state. The rails may be immovably fixed to the frame pieces and the drawer, respectively. The drawer may be mounted underneath the support structure. Arcuate guide fingers guide the engagement and disengagement of the first wheels from the second channels when the drawer is moved between the extended and pivoted states.

Abstract: A reverse number identification system is described which allows the called party in a telephone link to identify the telephone directory number of the calling party. This system includes a first system component located at the customer's premises which includes a display for the calling party's directory number. A second system component includes equipment connected to the calling party's telephone line located in the calling party's central office which transmits upon request the directory number of the calling party to the first system component. Each subscriber's telephone line in the central office has a microprocessor controlled transceiver placed between the incoming subscriber's telephone line and the central office switching equipment. Each subscriber's premises includes a first system component designed to receive and display the calling party's telephone number. In operation, the calling party dials the directory number of the called party and the called party responds by answering.
