Abstract: A high bandwidth gateway comprises a source of packet traffic wherein received packets are stored in a buffer, a destination interface circuit for the packets, a microprocessor and a bus that interconnects the components. The microprocessor, which in the prior art controls data transfers, periodically gives up control to a hardware assist engine. The hardware assist engine detects the presence of packets in the source buffer and causes the source buffer to output one or more packets to the destination directly, thus by-passing the microprocessor completely. By this system, bandwidth is improved by the source and the destination working together directly, without having the overhead associated with microprocessor-based or initiated data transfers.

Abstract: Stable emulsions of highly fluorinated organic compounds for use as oxygen transport agents, "artificial bloods" or red blood cell substitutes and as contrast agents for biological imaging. The emulsions comprise a highly fluorinated organic compound, an oil that is not substantially surface active and not significantly soluble in water, a surfactant and water.

Abstract: An improved lock for a filler cap having a cover adapted to be received within the tank opening with a retaining member connected at the lower face of the cover for cooperating with the wall of the opening to fasten the cap within the opening; the lock is mounted in the cover and extends downwardly toward the retaining member and the retaining member has cooperating means engagable with the lock when the retaining member is in the fastened position. The lock and the cooperating means prevent movement of the retaining member from the fastened position.

Abstract: A self-aligning dome nut having a base member for connection into a hole or aperture of a mounting plate by a pressing operation. The base member has a neck portion on one side for connection into the hole and a cavity on its other side into which a nut member is loosely positioned. A protective dome encloses the cavity and covers the nut member. The dome is connected to the base member to leave an exposed portion on its other side for direct application of a clamping force during attachment of the dome nut to the support member. An insulting washer is disposed around the neck portion of the base member between it and the mounting plate, the insulating washer is sized to electrically isolate the nut from the support member and preclude electrical arcing therebetween.

Abstract: An improved copper product and process of making it, wherein oxygen-free copper contains small amounts of manganese above normal impurity levels, and has enhanced grain size control during annealing, high electrical conductivity, and increased ductility as cast or fabricated. By adding approximately 1 to approximately 100 parts per million of manganese, the desired oxygen-free product has a minimum electrical conductivity of 100% I.A.C.S. By adding approximately 1 to approximately 50 parts per million of manganese, the desired oxygen-free product has a minimum electrical conductivity of 101% I.A.C.S. When at least approximately 30 parts per million of manganese are added to the oxygen-free copper, ductility is maximized. The manganese may be added at any convenient stage of producing the oxygen-free copper. The copper after annealing is free of or less subject to roughened surfaces or cracking.
