Abstract: This invention relates to a communication network intended for secure transmission of speech and data, including different types of subscriber terminals (10-15) and switching modules (4-6), and where the network further comprise crypto devices to undertake encryption/decryption of information transmitted through the network. At least one of the crypto devices is constituted by a crypto-pool device (7,8,9) having a number of crypto modules (CM) physically separated from the switching modules (4,5,6). Each crypto-pool (7,8,9; 20) is provided with a managing device (MA, 26) for communicating with a ciphering key distribution authority through standardized communication protocols and distribute keys to the relevant CM through a control path (25) of the crypto-pool. Each crypto-pool has access to an authentication server (AS, 16; 41,43) providing a directory of security certificates necessary in the authentication process when initiating a network connection.

Abstract: A process is described for the separation and recovery of isocyanate monomers from isocyanate concentrates which leaves a residue which is liquid and burnable. The process for the separation and recovery of isocyanate monomers from isocyanate concentrates formed in the production of isocyanates and comprising a volatile isocyanate monomer and by-products comprises the steps of: (A) preparing a mixture comprising (A-1) the isocyanate concentrate; and (A-2) an oil solution comprising; (A-2-a) a major amount of hydrocarbon oil, and (A-2-b) a minor amount of at least one ashless dispersant; and (B) heating the mixture to an elevated temperature at reduced pressure whereby isocyanate monomer is distilled and recovered leaving a liquid residue. The presence of the oil solution in the mixture facilitates the distillation of the isocyanate concentrate, generally improves the yield of distilled isocyanate monomer, results in a residue which is liquid and easily removed from the distillation apparatus, and the liquid residue can generally be burned without difficulty.

For this purpose, it is provided that both the activation for the performance of the function concerned and the activation of the display of the function concerned are executed simply with the aid of the function key concerned and that the selection of the two activation possibilities is affected by the manner and/or extent of the actuation of the function key concerned. It is furthermore provided that the user facilities which are possible or executable in the respective current operating mode of the terminal can be represented by the display device either in groups or individually by actuating the help key. <IMAGE>

Abstract: A semiconstrained prosthetic knee for surgical replacement of a dysfunctional knee includes a tibial platform, a movable bearing element, and a femoral component. The femoral and tibial components are typically constructed of a cobalt-chromium alloy and each includes an extension for securing the component to the bone. The femoral component includes a polycentric convex bearing which slidably engages a movable bearing, typically constructed of high molecular weight polyethylene. The superior surface of the bearing element is designed to congruently slidably engage the inferior surface of the bearing portion of the femoral component throughout the flexion/extension range of the knee. The inferior surface of the femoral component is generally convex with two or more offset portions of varying radii of curvature matching complimentary superior surfaces of the bearing element. The inferior surface of the femoral component may have more than one radii of curvature at different points along the convex surface. The superior surface of the tibial platform is generally flat and includes at least one protrusion for controlling the movement of the bearing element.

Abstract: A ring data network (such as a token ring network) is divided by a security unit (1) into first and second segments (6 and 8). The second segment (8) typically corresponds to one security group in the network. Logic in the security unit reads appropriate parts of each frame (typically the two address segments) to determine whether it is appropriate to forward the frame to the next segment of the ring. If the frame does not need to go to the next segment, or is not authorized to do so, then the security unit forwards instead a modified form of the frame in which its data cannot be read (except possibly by the security unit itself). In most cases the data content of the frame will be stored in the security unit. When the modified frame returns to the security unit at its second input port (4), the original frame can (if appropriate) be reconstructed, typically by reading its data content from a store in the security unit. In this way, the frame is returned to the secure group at the same time and in the same form as if it had travelled around the first segment of the ring, but there is no opportunity for stations in the first segment to eavesdrop upon the frame.
