Abstract: The subject of the invention is a device and a process for producing single-piece parts, including a bulk section and an elongated section, the device includes a die, formed from at least two half-shells, provided with an orifice for introducing material and bearing as a hollow the shape of the bulk section of the part, at least one of the two half-shells includes an extrusion orifice for producing the elongated section of the part. The process includes a step of pushing a slug of material into a die, provided with an inlet orifice and bearing as a hollow, the shape of the bulk section of the part, and a step of extruding a fraction of the slug to produce the elongated section of the part through an extrusion orifice of the die so as to form a blank of the part via a stamping-extrusion operation.

Abstract: Remote control of the use of computer data is described in a system for renting computer software which derives use and billing information, prevents unauthorized use, maintains integrity of the software and controls related intercomputer communications. A user at a target computer "downloads" programs or data, via a telephone line and remote control modules, from a host computer. Usage of the programs or data by the target computer or other accounting data are recorded and stored and, at predetermined times, the host computer "uploads" the usage data for processing. Other features include: (1) software and usage security for rental programs; (2) a polynomial generator/checker for generating block check characters for assuring integrity of data transmitted and received; (3) a voice-data switch for switching between data communication and normal telephone communication; and (4) an audio amplifier and speaker for monitoring of activity on the communication line during data transfers.

Abstract: Remote control for the use of computer data and video game software is described in a system for renting computer software which derives use and billing information, prevents unauthorized use, maintains integrity of the software and controls related intercomputer communications. A user at a target game computer "downloads" programs or data, via a telephone line and remote control modules, from a central host computer. Usage of the video game software or data by the game computer or other accounting data are recorded and stored and, at predetermined times, the host computer "uploads" the usage data for processing.
