Abstract: An intercom system is provided having a plurality of intercom stations coupled to a digital network, each station transmitting intercom data onto a channel of the network. Each station receives intercom data from each other station and selects channels to be amplified and output to a speaker. Each station may listen to and talk to any other station or any selected group of stations. Processing of signals from the network is performed in each station, thereby eliminating the need for a centralized mixing and switching device. Stations may be added merely by connecting them to the network. The intercom system may be configured in a non-blocking mode or in a blocking mode.

Abstract: A method of injection molding an over-molded article in which a cavity extension associated with a core is first moved to a disengaged position and the core is inserted into a first cavity having a defined volume in a first geometrical configuration. A first injection operation is performed into the first cavity to form a first layer of the article. The core is then removed from the first cavity with the first layer of the article on the core. The cavity extension is moved to an engagement position and the core and first layer are inserted into a second cavity. The second cavity and the cavity extension engage to form a composite cavity having a larger volume than the defined volume and define a second geometrical configuration. A second injection operation is performed into the composite cavity to over-mold the first layer to form the article. The core and cavity extension are separated from the second cavity to remove the article therefrom.
