Title: Routing apparatus and method for high-speed mesh connected local area network
Inventor: THACKER CHARLES P
IPC: G06F15/173
Filed: 1990-03-02
Granted: 1998-05-19
Abstract: A packet routing apparatus allows numerous packets to be routed  simultaneously through a mesh connected network. The  network  consists  of  a  number  of  interconnected switches which are coupled, in turn, to the hosts that are members of the local network.  The switches are nonblocking switches that are coupled to each other and to the hosts by a multiplicity of point to point links.  Each switch has a routing mechanism for automatically  routing  received packets toward their specified destinations. For each received  packet  the  router  generates  a  routing mask representing the output links that may be used to route the packet towards its destination.  The routing mask includes a broadcast bit. If the broadcast bit is ON, the packet must be simultaneously routed to all of the output links specified by the routing mask.   If the broadcast bit is OFF,  the packet may be routed on any single one of the links specified by the routing mask. To ensure that every packet makes progress towards its destination, packets are processed in the order of their arrival by placing the corresponding routing masks in a queue.  Periodically, the set of available output links is compared with all of the routing masks. Using  a  first  come,  first  considered routing discipline, the first routing mask in the queue to match the available output lines is selected.   A routing selection is then generated for the corresponding packet and the selected routing mask is removed from the queue.

Abstract: A hollow polysulfonic fiber intended for a selectively transmissive membrane contains a hydrophilic polymer which is cross-linked into a water-insoluble form (for example polyvinylpyrrolidone) and is used in the form of a hydrogel containing water. A method for the production of a membrane module consists in spinning a hollow fiber by the use of a spinning solution containing a polysulfonic resin and a hydrophilic polymer, wetting the fiber above the saturated moisture content, and then, with the wet condition maintained, subjecting the fiber to the processes of module molding and radiation induced cross-linking, these processes being performed in either order. The method provides a selectively transmissive hollow polysulfone fiber membrane which displays less elution into water and a sharp molecular weight fractionation, so as to be usable safely in the fields of medicine and foodstuffs.

Title: Continuous autocirculation, multiple zone mass transfer apparatus and method
Inventor: HARDISON LESLIE C
IPC: C10K1/12
Filed: 1992-04-07
Granted: 1999-05-04
Abstract: An apparatus and method of contacting a liquid with different gases sequentially in separate mass transfer zones within a single vessel, the mass transfer zones operatively connected in liquid communication with each other, including intimately contacting the liquid with a first process gas in cocurrent flow in a first mass transfer zone to effect mass transfer between the first liquid and the process gas, and introducing the liquid into a second mass transfer zone with a second gas, different from the first gas, in cocurrent flow with the second liquid, thereby effecting mass transfer between the second liquid and the second gas.  The rate of flow of the liquid from said first mass transfer zone to second mass transfer zone and recirculation to the first mass transfer zone is motivated by the difference in density of the contents of the liquid phase portion of each mass transfer zone and a following liquid downcomer or flow channel connecting it to the next sequential mass transfer zone, such that after passing through the last mass transfer zone, the liquid recirculates to the first mass transfer zone.  The apparatus and method are ideally suited to carrying out the process of hydrogen sulfide removal from gases by means of an air-regenerated liquid redox catalyst, such as chelated iron.

Title: Mechanism for coupling a component with a vehicle
Inventor: HUTCHISON WAYNE R
IPC: B62D49/06
Filed: 1992-06-09
Granted: 1994-10-04
Abstract: A mechanism for coupling vehicle components to a vehicle frame made of a plastic material.  A bolt is received by generally aligned openings defined by the frame and the component, and a first nut threaded onto the bolt securely presses the frame and component together.  A spacer or second nut carried by the bolt between the first nut and the component is positioned within the opening in the frame.  The spacer is slightly smaller in depth than the frame member, and allows the frame to become slightly compress.  The spacer limits the travel of the nut on the threads, thereby preventing the frame from being compressed beyond an elastic range of deflection.  A module plate having the vehicle engine thereattached is carried between the second nut and the vehicle component.  The second nut keeps the module plate and the component securely coupled together when the first nut is removed from the bolt, such that the module plate, the engine and the vehicle component can be removed from the frame as a single unit.
