Title: Three-dimensional seismic prospecting method
Inventor: GALLAGHER JOSEPH G
IPC: G01V1/30
Filed: 1990-04-25
Abstract: Abstract of the Disclosure A 3-D seismic prospecting method is provided which employs an areal array of sources and receivers by which seismic traces are generated.  The areal array is segregated into a plurality of shells and angularly separated sections from which a preselected number n1 of source-receiver pairs are selected for a particular common midpoint.  By means of the shells and sections, the source-receiver pairs so selected have associated therewith a wide range of offsets and azimuth angles for the preselected fold n1.   The seismic traces corresponding to the selected source-receiver pairs are summed to give a stacked trace corresponding to the common midpoint.

Abstract: CLUTCH-TO-CLUTCH CONTROL IN AN AUTOMATIC TRANSMISSION         ABSTRACT OF THE DISCLOSURE         In an automatic transmission, upshifting is controlled by ramping down the pressure in an off-going clutch associated with a high speed ratio and increasing the pressure in an on-coming clutch associated with a lower speed ratio.  The on-coming clutch has commanded pressure at a maximum value for an initial fill time, a lower increasing ramp value during the ramp of the off-going clutch until the on-coming clutch starts to engage, and then a closed-loop control until the clutch reaches a synchronous speed.  The closed-loop control parameter is on-coming clutch slip speed which is controlled to a calculated slip speed profile.  The profile has a first steep slope and a final less steep slope so that the actual slip can smoothly go to zero in a given time period.

Title: Trilevel performance gas generator
Inventor: MINERT ROY T
IPC: B60R21/263
Filed: 1990-10-18
Abstract: ABSTRACT OF THE DISCLOSURE A gas generator which may be used for ejecting submunitions. The gas generator comprises a diffuser chamber which is flanked by differently sized combustion chambers whereby three different ejection velocities may be achieved by firing only one of the combustion chambers or by firing both of them together. The generated gas is exited from the gas generator at the same central location, i.e., the centrally located diffuser chamber, to control submunition yaw and loading locations. The provision of combustion chambers at opposite ends of the diffuser chamber permits minimization of gas generator diameter, and a tie member in the diffuser chamber permits a non-complicated and inexpensive structure which is rugged and reliable. The gas generator may have other applications such as for inflating airbags for automobiles.

Title: Aquatic animal feeding assembly
Inventor: REID BRUCE A
IPC: A01K61/85
Filed: 1990-11-09
Abstract: ABSTRACT            This invention  relates to an assembly for the automatic feeding of aquatic animals, particularly fish, in an aquarium.     In use the assembly  is disposed  atop an  aquarium or  atop an aquarium hood with an opening congruous with  a passage  of a   feed chute contained in  the assembly.   The end-user fills each compartment of a train, mounted on a  steeply sloping  ramp, with particulate or  flake-type  feed  of  his  or  her  choosing.    The train is restrained, from sliding down and dumping its contents through an aperture  in  the  ramp,  by  a  string connected to a float in a reservoir suspended in fluid  communication above  an evaporation tray.  Liquid  that evaporates  from the  tray is replaced with liquid from the reservoir, causing the float to descend.   As the float descends,  the attached  train is  allowed to advance under gravity's pull.   Upper surface  of the  ramp forms  a bottom for the train;  hence, as  the train  advances over  the aperture the feed falls freely through the aperture,  down the  chute and into the aquarium.
