Title: Surfactant-stabilized foams
Inventor: AYASSE CONRAD
IPC: C09K8/94
Filed: 1990-05-24
Granted: 1994-11-01
Abstract: A foam is provided for use in a subterranean oil-bearing formation for reducing and controlling the mobility of a gaseous drive fluid.  The foam is generated using an inert gas and a fluorocarbon surfactant solution in admixture with an amphoteric  or  anionic  hydrocarbon  surfactant  solution.    A relatively  small  amount  of  the  fluorocarbon  surfactant  is operative, when mixed with the hydrocarbon surfactant and foamed, to generate a foam that has better stability when in contact with oil than a foam made with hydrocarbon surfactant alone.

Title: Cellular radio-telephone receiver employing improved technique for generating an indication of received signal strength
Inventor: ROBERTS GLYN
IPC: H04B1/30
Filed: 1992-03-18
Granted: 2002-05-28
Abstract: In a digital radio-telephone receiver, an open-loop arrangement for generating a received-signal-strength-indicating ("RSSI") value suitable for use in mobile assisted hand-off within a cellular telephone system. The receiver has an amplifier for amplifying a received signal with a gain controlled by a gain-control signal, and an automatic-gain-control circuit ("AGC") responsive to the amplitude of the amplifier output and, coupled in a feedback-loop for applying an AGC signal to the amplifier as the gain-control signal. An RSSI value is generated by (i) opening the AGC feedback loop so that the AGC output signal is not applied to the amplifier, (ii) applying a ramp signal of increasing amplitude to the VGA while the AGC monitors the signal envelope, and (iii) when the signal envelope passes a pre-selected threshold, applying the then-occurring ramp-signal value to a calibrated look-up table to obtain the corresponding RSSI value stored therein.      Preferably, the receiver also employs a digital multiplexer ("MUX"), which provides to the amplifier as the gain-control signal, in response to a select signal, the ramp signal during a first period of time, and the AGC signal during a second period of time.

Title: Combination ice and chilled beverage dispenser
Inventor: SCHROEDER ALFRED A
IPC: B67D1/07
Filed: 1990-11-14
Granted: 1995-06-27
Abstract: This invention relates to apparatus  for dispensing both ice and chilled beverages and to an improved chilled beverage dispenser which has large ice storage capacity and which incorprates an improved system of dispensing ice.  Ice in chilled beverages has become a necessary part of modern-day food service, and combined ice and chilled beverage dispenser increases efficiency by eliminating the need for two separate machines and by making more counter space available.  The present invention utilizes a circular rotating tray (20) which lifts ice stored below the height of the discharge chute (12) to an elevation above said chute and then into a secondary cone chute (22) for gravity-assisted dispensing.   This design allows the rotating tray (20) to reach throughout the entire height of the ice storage bin (30) with utilization of the entire volume of bin (30) while still dispensing proper volumes of ice at appropriate height levels.

Title: Modified factor vii anticoagulant proteins
Inventor: BERKNER KATHLEEN L
IPC: C07K14/745
Filed: 1991-01-25
Granted: 2000-11-14
Abstract: Factor VII of the coagulation cascade is modified to act as an anticoagulant.  Amino acid modifications are employed to produce a modified Factor VII having a substantially reduced susceptibility to activation by enzymes which typically activate wild-type Factor VII. The modified Factor VII is able to compete with wild-type Factor VII and/or VIIa for binding tissue factor, inhibiting clotting activity. As the modified Factor VII acts specifically to interrupt the coagulation cascade, pharmaceutical compositions of modified Factor VII may be administered in place of, or in conjunction with lower doses of, conventional anticoagulant therapies.

Abstract: An  exhaust  system  is  provided with  a  stamp  formed connector for joining a pair of upstream exhaust pipes to at least one downstream exhaust pipe.   The connector includes a pair of plates that are formed to define opposed channels.  The plates are secured in face-to-face relationship such that the channels define exhaust passages extending between the plates.  The passages are curved to achieve the most desireable routing of exhaust pipes.          Additionally, the exhaust pipes may be bent in close proximity to the connector to achieve most efficient routing of pipes on the vehicle.  The bending of the pipes and the curved configurations of the passages in the muffler are intended to substantially equalize travel lengths for exhaust gases between upstream ends of the exhaust system and the muffler.
