Abstract: A process for preventing the unwanted transmission of information from a client computer to a host computer on the Internet. The process analyzes the HTML contents of a user-accessed Web page during the assembly of the Web page for display on the client computer. After identifying the domain name of the Web page and comparing that domain name to domain names of host computers from which elements of Web page will be obtained, the process prevents unwanted transmission of data from the client computer to such host computers by processing requests for such elements through a cookie filter and/or a URL filter. Upon examination of all requests for the transmission of data and the prevention of any unwanted transmission of such data, the process displays the accessed Web page on the client computer with or without the display of certain Web page elements depending upon the user's choice.

Abstract: An attachment is provided which includes a support member of L-shaped cross section having a first aperture in one leg through which a grinding wheel may extend and a second aperture in the other leg for receiving the shaft of the grinding wheel. An adjustably mounted plate having a third aperture therein is secured to the second leg and arranged to be brought into spaced relation to the first leg so that the first leg and the plate may ride along the opposite faces of the chain saw bar for effectively guiding the attachment and a grinding wheel mounted thereon along the edge of the bar. To effect grinding of the face of the chain saw bar the same attachment is employed but is positioned so that the plate rides along the edge of the chain saw bar to provide an effective guide. In addition the first and third apertures are shaped for receiving and firmly holding a file for filing the edge of the chain saw bar as the attachment is moved along the bar.

Abstract: A system for aligning and regapping the guide grooves on a chain saw guide bar which includes a suitably adapted handheld swaging tool uniquely designed to return bent or worn guide grooves to the correct position and separation. The swaging tool contains a gauge which is adapted to fit in the center of the bar guide groove and a pair of swaging plates which are adapted to force the walls of the bar guide groove into proper relationship with one another upon the application of force to the swaging tool. The system may optionally further include a bar file guide which is adapted to file the peripheral edges of the chain saw bar.
