Abstract: A generic communications network provides an encrypted communications interface between service networks and their subscribers. When communications are initiated between a subscribing communications terminal and the generic network, the terminal compares a stored network identifier associated with a stored public key, with a unique identifier broadcast by the generic network. If a match is found, the terminal generates a random secret key, encrypts the secret key with the stored public key, and transmits the encrypted secret key. The generic communications network decrypts the secret key using a private key associated with the public key. The secret key is used thereafter by the terminal and the generic network to encrypt and decrypt the ensuing radio traffic. Consequently, the network can maintain secure communications with the terminal without ever knowing the terminal's identity.

Abstract: A turret style printing machine (10) includes a first tier (16) of pallet supporting members (14), a second tier (20) of printing head supporting members (18) and a third tier (24) of printing head supporting members (22). One can thus selectively move either a second tier member (18) or a third tier member (22) into alignment and registration with a first tier member (14). A uniform registration is further provided ensuring the second third tier supporting members consistently align with the first tier supporting members (14). This expansion increasing the number of stations is accomplished without necessarily increasing the required floor space or system diameter.

Abstract: A form tie for joining the sidewalls of a polymeric concrete form comprises a pair of end trusses with an intermediate web truss. Each end truss comprises a pair of vertical struts with interior and exterior pairs of horizontal struts extending therebetween. The width of the web truss corresponds to the desired lateral distance between the interior surfaces of the form sidewalls. Upper and lower rectangular trusses and an intermediate truss are formed within each truss and rigidified by diagonal struts. The exterior struts of each end truss are embedded in the polymeric form of the sidewalls during the molding process with the interior struts of each end truss sealing the mold openings to prevent expansion of the foam from the mold. The interior struts are coplanar with the form sidewalls and serve as a visual gauge that the form and tie have been properly positioned. End ties having a height of one-half of the form sidewall are extended between the sidewalls at the ends of each form.

Abstract: Light-emitting diodes are positioned directly under each key of a multi-key flexible pad of a keypad assembly. Each of the light-emitting diodes is disposed within a cavity formed in the lower surface of a respective key whereby all of the light emitted by the diode is transmitted directly into the key. In one embodiment, the light-emitting diodes are mounted on a flexible film disposed between the flexible pad containing the keys and a flexible sheet having a plurality of raised domes. In a second embodiment, the light emitting diodes are mounted on the upper surface of a printed circuit board. The keypad assembly addresses the problem of low light transmission efficiency through light guides, or the use of individual optic fibers to illuminate each of the keys. Furthermore, the keypad assembly, by the elimination of light transmitting structures within the keypad assembly, enables the design of thin-section telecommunication instruments.
