Abstract: Computer-implemented methods, systems, and computer-readable media for detecting the presence of malicious computer code in an e-mail sent from a client computer (1) to an e-mail server (2). An embodiment of the inventive method comprises the steps of: interposing (41) an e-mail proxy server (31) between the client computer (1) and the e-mail server (2); allowing (42) the proxy server (31) to intercept e-mails sent from the client computer (1) to the e-mail server (2); enabling (43) the proxy server (31) to determine when a file (30) is attempting to send itself (30) as part of an e-mail; and declaring (44) a suspicion of malicious computer code when the proxy server (31) determines that a file (30) is attempting to send itself (30) as part of an e-mail.

Abstract: An elastic pipe-connecting component for pipes or pipelines or the like, comprises an elastic sleeve with flanges at each end and an annular expansion bulge in its midportion. In its undeformed condition, there is a cylindrical section on each side of the bulge, between the bulge and the portion of the component that is clamped to the pipe or pipeline. These exposed cylindrical portions are adapted to expand outwardly, to form two additional bulges, upon the imposition of pressure. To this end, they are reinforced with fibers of glass or steel or high strength synthetic, which are disposed at an angle to the axis of the component, of less than 55.degree.. A desirably long component is thus provided, from a minimum of material.
