Abstract: Examples include releasing flammable gas from a container interior, via through-passage gaps of a metal structure cylindrical flame barrier secured in a hole through a wall of the container, to an exterior region as released flammable gas, and combusting the released flammable gas in the exterior region. The cylindrical flame barrier extends a height, has an internal facing end that faces the container interior and has an external end that extends from top side of the wall to the other end, by an amount least a fifth of the cylindrical barrier's overall height. The external end absorbs combustion heat energy. The projecting portion radiates the absorbed heat energy. The radiating is determined in part by the projecting height, and is configured to maintain the interior facing end at a temperature below the combustion temperature of the gas.

Abstract: The invention comprises an apparatus for covering an exposed end of a severed sternum, comprising a strip operative to cover the exposed end and pliable portions which are able to be manually deformed over sides of the exposed end so as to retain the strip against the exposed end to stop or at least reduce flow of blood from the exposed end.

Abstract: A flashback preventer with a cylindrical flame trap which is installed in a wall, separating an at-risk region from an external region, and has a cross-sectional surface area containing a plurality of throughflow gaps and a height determining the length of the throughflow gaps and an underside directed towards the at-risk region, and an upper side directed towards the external region, can be formed with a low mass and high energy-dissipation efficiency in that the flame trap is inserted into an opening in the wall, said opening corresponding to the cross-sectional surface areas of the flame trap, and has at least a fifth of its height projecting beyond the wall into the external region.

Abstract: The invention comprises an apparatus (10) for covering an exposed end of a severed sternum, comprising a strip (12) operative to cover the exposed end and pliable portions (14) which are able to be manually deformed over sides of the exposed end so as to retain the strip (12) against the exposed end to stop or at least reduce flow of blood from the exposed end.

Abstract: A switching valve having a valve seat with a longitudinal axis (L) and having a valve plate with a valve plate surface which can be placed into a pass-through position, in which the switching valve is open, and into a closed position, in which the switching valve is closed and the valve plate bears with the valve plate surface, in a contact region, against the valve seat, wherein the valve plate has a modulus of elasticity of at least 1000 N/mm2, which switching valve is characterized in that the valve plate, in the closed position, is deformed by a closing force acting thereon, in such a way that the contact region of the valve plate surface in the closed position forms an angle ?, which differs from 0°, with the contact region of the valve plate surface in the pass-through position.

Abstract: The invention relates to a control valve having a valve seat and a valve disk (1), which can be moved from a closed position, in which the valve disk (1) rests on the valve seat and the relief valve is closed, into a through-flow position, in which the relief valve is open, wherein the valve disk (1) comprises a valve disk surface (2) having a peripheral surface rim (4) and a normal which is perpendicular to the valve disk surface (2), runs through the center of gravity of the latter and defines a longitudinal axis L. A brim is arranged on the surface rim (4), wherein said brim has a first part (6) which projects beyond the valve disk surface (2) in the axial direction with respect to the longitudinal axis L and has a second part (8) which adjoins the first part (6) and comprises a section that is radial with respect to the longitudinal axis L.

Abstract: In a flame arrester arrangement having a housing (1) for holding at least two flame arrester inserts (6, 6?) having a large number of axial passage gaps dimensioned for a combustible gas, and having an intermediate layer (7) arranged between two flame arrester inserts (6, 6?), which permits a radial distribution of the gas flow emerging from one flame arrester insert (6, 6?) and entering an adjacent downstream flame arrester insert (6, 6?), the ability of the flame arrester inserts (6, 6?) to be easily assembled and disassembled for servicing purposes without restricting the functional integrity can be achieved by at least one separate closed seal (11, 11?, 15, 17, 17?, 20) being arranged between a flame arrester insert (6, 6?) and the housing (1) or between two flame arrester inserts (6, 6?) in such a way that a flow around the flame arrester insert (6, 6?) in a space (12) located radially outside the passage gaps is prevented.

Abstract: An intra-session network correlation system receives a stream of network events and groups the events into different network sessions according to event parameters and corresponding network address translation (NAT) information. An event in the stream is first matched against any existing session, and then categorized using the information about a NAT device that translates a message to which the event is related. Finally, at a predefined time, a categorized event is processed to identify other categorized events in accordance with a NAT message or an expiry timer associated with the categorized event; the categorized event and identified other categorized events are grouped into the same network session.

Abstract: A data processing method and apparatus are proposed for used in the encryption, decryption and authentication of messages. A memory for storing input information, a set of operations and a processor for executing the operations on the stored input information are provided. The input information is utilized to select the order and number of operations performed. The operations are devised such that any possible input string will be interpreted as a valid program and the memory is extensible. Furthermore, data is output as a function of the input information. As a result the state of the memory generated during execution is indeterminate prior to execution and the process evolves differently for each possible input string. Accordingly, the process performed by the module cannot be described by an algorithm.
