Patent CA-2039459-A1 (CA)
Inventor: DAVIS RICHARD S
IPC: F01L3/20
Filed: 1991-03-28
Abstract: An intake port pressure control system comprises an intake passage leading to a cylinder in an engine, and a check valve in the intake passage to allow fluid flow toward the cylinder and obstruct fluid back-flow in the reverse direction.  A bypass port is located on the intake passage so that the bypass port communicates with a trapped volume defined by the portion of the intake passage between the check valve and intake valve.  The intake port pressure control system further comprises a control valve having an outlet passage, a secondary passage, and an actuator enabling communication between the outlet passage and secondary passage.  The actuator further enables active adjustment of the flow area of the flowpath between the secondary passage and outlet passage throughout a range of engine operating conditions.  The outlet passage is connected to the bypass port, and the secondary passage is connected to a secondary air source.  The control valve enables a controlled air flow therein from the secondary air source into the trapped volume when the intake valve is closed.

Title: Method for steam flooding profile control
Inventor: SHU WINSTON R
IPC: E21B43/24
Filed: 1991-05-01
Abstract: ABSTRACT      A method for minimizing well recompletions in a multiple zone hydrocarbonaceous fluid containing formation.  A steam flooding enhanced oil recovery (EOR) is conducted in the upper zone of said formation via fluidly communicating injector and producer wells which penetrate the upper and lower zones.  The wells are unperforated and do not communicate with each other in the lower zone.  Thereafter, a temperature activated gellable composition is injected into the upper zone where it forms a solid gel.  Afterwards, both wells are perforated so as to fluidly communicate with each other in the lower productive interval.  Subsequently, a steam-flooding EOR operation is conducted in the lower level and hydrocarbonaceous fluids are removed therefrom. Polymers utilized in the gellable composition include polyvinyl alcohol and polyacrylamide cross-linked with phenol and an aldehyde producing compound sufficient to form a phenolic resin in situ.

Abstract: A locomotive control system having a single handle movable between a maximum propulsion position, through diminishing propulsion positions, through a release/idle position, through increasing braking positions, through a full service brake position to an emergency brake position.  The control system receives position signals from the handle and generates propulsion, dynamic braking and fluid braking control signals as a function of the position signals.  For any braking position of the handle, the control system first applies or removes dynamic braking and then provides fluid braking depending upon the position of the handle, the type of train brakes and whether the dynamic braking has maximized or is zero.
