Title: Router pooling in a network flowswitch
Inventor: BHASKARAN SAJIT
IPC: H04L69/40
Filed: 1998-12-04
Abstract: A router fault tolerant network interface system (300) includes a switch circuit (302) configured to detect when a router fails in a multi-router local network. When a failed router (202) is detected, the switch circuit (302) waits for a time-out period to expire to allow convergence. The switch circuit (302) then intervenes when traffic from a server (106) to the failed router (202) is detected. The switch circuit (302) translates the MAC address of the failed router (202) to the MAC  address of a functional router (104). Traffic from a server (106) originally directed to the failed router (202) is then redirected to a functional router (104). In a further refinement, the switch circuit (302) provides the MAC address of a functional router (104) in response to an ARP request from a server (106) to the failed router (202).

Title: Breast pad
Inventor: LEEDER SHERY D
IPC: A61F13/14
Filed: 2000-11-27
Abstract: A breast pad for absorbing fluid near a nipple is disclosed.  The breast pad has an outer layer made from a substantially circular piece of absorbent material with a stitched radial tapering fold such as a dart which is deformable to a substantially concave or conical shape to substantially cover the nipple. The breast pad also has an intermediate layer of absorbing material having a shape which assists the intermediate layer to conform to an inside surface of the substantially concave shape of the outer layer. The intermediate layer is attached to the outer layer in a radial position corresponding to the stitched tapering fold such that the intermediate layer substantially covers the stitched tapering fold. In this way, the intermediate layer provides additional absorbent material near the nipple, and, prevents direct contact of the stitched tapering fold with the nipple. The breast pad also comprises an inner layer made of a hydrophilic material which dries substantially faster than the intermediate layer and draws fluid away from the nipple and towards the intermediate layer and the outer layer. To assist in orienting the intermediate layer near the bottom of the nipple, the intermediate layer has a perceptively different colour than the outer layer.

Abstract: The present invention sets forth techniques for channelizing and encoding various broadcast information services using, for example, a broadcast control channel to provide information to a mobile station user. The mobile station may be a receive-only device, similar to a simple pager, or may be a receive/transmit device, such as a mobile phone. In order to limit the capacity of the broadcast channel that is consumed by, e.g., a Security Quote service, an efficient encoding and channelization method is provided. The method includes separating the short-message-service broadcast control channel into 3 logical sub-channels: a Security Name channel, a Start Value channel and a Delta channel. These channels provide different aspects of the securities information to the mobile station. By varying the bandwidth allocation of these individual channels, the present invention is capable of providing a very large amount of securities while also maintaining a fast cycle time.

Title: Method and apparatus for effecting gas-liquid contact
Inventor: SMITH JAMES W
IPC: B01J10/00
Filed: 1993-04-05
Abstract: Components, usually but not exclusively gaseous components, are removed in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. The same principle may be employed with other procedures in which a gaseous phase is dispersed in a liquid phase to effect an interaction between components present in such phases, for example, to treat or strip or react a component of the liquid phase. A gas-liquid contact apparatus, which may be a combined chemical reactor and solid product separation device, also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index of gas through the openings in the shroud is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area corresponding to an equivalent diameter less than about one inch.
