Abstract: Apparatus and methods are provided for a self-contained tension control system. An example self-contained tension control system can include a brake system configured to provide tension friction to a web, a tension transducer to provide tension information indicative of tension of the web, a controller configured to receive the tension information, to compare the tension information to set point information, and to provide a command signal to the brake system, and an enclosure configured to enclose the brake system, the tension transducer, and the controller, the enclosure including a first web opening and a second web opening configured to allow the web to enter the enclosure and to pass through the enclosure to equipment downstream of the self-contained tension control system.

Abstract: A tension station can include a single brake device configured to provide tension to multiple webs, a nip roller configured to nip the multiple webs to a component of the brake device, a tension transducer idler configured to support the multiple webs and to provide tension information indicative of tension of one or more of the multiple webs, and a controller configured to receive the tension information, to compare the tension information to set point information, and to provide a command signal to the brake device;

Abstract: The present invention involves one or more computers that provide software controls to enable a web application to interface with a personal trusted device. The server side of the computer system comprises: a server-based framework process; a device for receiving requests from the client computer and determining which software controls to send in response; and a device for digitally signing and encrypting the software controls before sending them to the client computer so that their authenticity can be verified. The client side of the computer system comprises: a client web browser that runs on a computer; a device for transmitting requests to the server computer and for receiving responses from those requests; a device for decrypting software controls so that the authenticity of their digital signature can be verified; and a connection to one or more personal trusted devices. An authentication proxy may be used to mutually authenticate a client user and server process using personal trusted devices.

Abstract: A shaft (12) for a pump (10) or other rotating machine, made substantially out of only engineering plastic—such as the polymer PEEK or some other selected polymer—and including portions having respective surfaces (12a-d) serving as bearing surfaces, the shaft (12) thus integrating the functions of both a shaft structure and a bearing structure. In some applications, the shaft (12) includes both portions having respective surfaces serving as radial bearing surfaces (12a-b) and also portions having respective surfaces serving as thrust bearing surfaces (12c-d), all made from the same engineering plastic as the rest of the shaft (12) and formed as part of the shaft (12). The engineering plastic may include one or more additives such as PTFE or carbon fiber, especially in case of dry-run applications.
