Title: Methods for preparing 1,3-butylene glycol
Inventor: GUAJARDO RICHARD D
IPC: C07C45/72
Filed: 2005-01-03
Abstract: 1,3 butylene glycol, prepared through an intermediate aldol condensation reaction of acetaldehyde, is produced at increased yield efficiencies. The efficiencies are achieved by utilizing an acetaldehyde having low carboxylic concentrations. The aldol condensation takes place in the presence of an alkali agent at a concentration of about 2 ppm to about 10 ppm to produce a 3-hydroxybutanal intermediate product that is hydrogenated in the presence of a Raney nickel catalyst to yield 1,3 butylene glycol at efficiency yields of greater than about 75%.

Title: Dual arc vane pump
Inventor: PATTERSON ALBERT W
IPC: F04C2/324
Filed: 2006-07-19
Abstract: A rotary, positive displacement pump for fluids, having a pair of diametrically opposed vanes secured to a rotor in equally spaced, similarly contoured pockets, for movement between an extended position with a portion of the vane extending outwardly beyond the cylindrical surface of the rotor and a retracted position wherein the vane is seated entirely within its corresponding pocket.  Each vane is formed of a top curved portion and a bottom curved portion, these portions meeting along a longitudinally extending line. The top portion extends from a pivot to the line and is curved so that when the vane is in retracted position it sits in a peripheral depression extending longitudinally along the rotor surface, the outer surface of this top portion of the vane conforming to the cylindrical surface of the rotor. The bottom portion is curved along a radius from that pivot, so that this lower portion is seated in and fills its corresponding pocket when the vane is in retracted position. The pump construction according to the present invention permits the use of smaller rotors and relatively larger vanes.

Title: Congestion handling in a packet communication system
Inventor: BROWN JACK E
IPC: H04L12/56
Filed: 2005-01-25
Abstract: A packet communication system (300) is disclosed that includes an end communication device (302), a call processing system (306), and a packet network (304). To setup up a call from an end user, the end communication device (302) transmits a call request message to the call processing system (306). The call request message has a header that includes priority information for the call. The call processing system (306) processes the priority information in the header of the call request message to determine if the call request message is for a high priority call. If the call request message is not for a high priority call and the call processing system (306) is in a state of congestion, then the call processing system (306) transmits a response message indicating the state of congestion. Responsive to receiving the response message, the end communication device (302) performs call blocking and provides call treatment to the end user.
