Abstract: A communication system includes station ports for connecting station sets to the system. A port circuit includes a number of conference registers which are not dedicated to particular station ports but rather are assigned as needed to port circuits. When a request is made to form an N party conference call, N-2 available ones of the conference registers are then assigned to each port of the port circuit which is involved in the resulting conference call connection.

Abstract: A method for the deposition of filler materials in filling and overlay applications is disclosed in which there is provided a continuous forced flow of filler material from an external reservoir, which is released through an outlet positionable over a depression in a surface which has been prepared to be filled and overlaid with filler to fill the place of application and overlay the surrounding area. An apparatus for the deposition of such filler is also disclosed.

Abstract: A transmission arrangement for use in a customer premises communication system is operable for controlling transmission during the MF digit signaling interval in situations where it is necessary to convert station dialed MF signals to pulsed digit signaling. In systems where the signaling station, the MF to dial pulse converter and the Central Office or PBX line are bridged on the same communication link it is possible for the station's MF signals to be detected by the MF receiver in the Central Office, thereby causing errors in the received digits. These problems are eliminated by inserting two transmission gates in the four-wire portion of the CO line. The gates are controlled by the processor in the customer premises communication system such that the outward gate is opened immediately upon seizure of the line by the calling station and remains open during the entire dialing interval.

Abstract: A U-shaped molded plastic furniture frame for use in fabrication of a barrel shaped chair. Each end of the frame has a box portion formed therein for receiving a front support member of a desired length to provide a chair having a preselected width. The frame also has facilities integrally molded therein for receiving the arms, legs and backs of a chair. Additionally, other facilities may be provided for the easy attachment of springs, spring supports, or other support members to the frame.
