Publication number: 20230323193Abstract: Embodiments of treating fluid comprising hydrocarbons, water, and polymer being produced from a hydrocarbon-bearing formation are provided. One embodiment comprises adding a concentration of a viscosity reducer to the fluid to degrade the polymer present in the fluid and adding a concentration of a neutralizer to the fluid to neutralize the viscosity reducer in the fluid. The viscosity reducer is buffered at a pH of 7 or less (e.g., at a pH of from 2 to 7, such as at a pH of from 3.5 to 7, or at a pH of from 5 to 7). The addition of the concentration of the viscosity reducer is in a sufficient quantity to allow for complete chemical degradation of the polymer prior to the addition of the concentration of the neutralizer in the fluid such that excess viscosity reducer is present in the fluid.Type: ApplicationFiled: January 27, 2023Publication date: October 12, 2023Inventors: Sujeewa S. PALAYANGODA, Kerry Kennedy SPILKER, Sumitra SUBRAHMANYAN, Gayani W. PINNAWALA, Sophany THACH, Gregory A. WINSLOW, Dennis Arun ALEXIS, Harold Charles LINNEMEYER, Timothy P.

The addition of the concentration of the viscosity reducer is in a sufficient quantity to allow for complete chemical degradation of the polymer prior to the addition of the concentration of the neutralizer in the fluid such that excess viscosity reducer is present in the fluid. The addition of the concentration of the neutralizer is sufficiently upstream of any surface fluid processing equipment to allow for complete neutralization of the excess viscosity reducer such that excess neutralizer is present in the fluid prior to the fluid reaching any of the surface fluid processing equipment.Type: GrantFiled: October 22, 2019Date of Patent: February 8, 2022Assignee: Chevron U.S.A.

Patent number: 6064792Abstract: A device for recording and playing back a selected episode from an input analog audio-visual signal. A "deferred recording" feature allows the user to briefly delay his/her decision to record a live signal episode until after the signal episode has at least partially transpired. Thus, the user can first evaluate the episode prior to deciding whether to record it. The recorded signal episode contains both preamble and postamble segments, i.e. the signal segments preceding and following activation of a record switch. The analog playback signal is directed to an A/V output device so it can be heard/viewed by the user. Some embodiments provide for recording multiple signal episodes, multi-signal channel episodes, variable length episodes, simultaneous record and playback, episode deletion, variation of sampling rate, skip forward, reverse, and squelch.Type: GrantFiled: August 2, 1997Date of Patent: May 16, 2000Inventors: James Kelly Fox, Harold Charles Schloss, Clinton Gregory White

Patent number: 4084261Abstract: A graphic display apparatus in which the data to be displayed is stored as two types of data word, one type representing groups of increments of beam displacement of a beam displacement tube and the other representing differences between the data constituting a raster line and that of next succeeding line. The data for each line formed from the first type of words is temporarily stored in a line store while being displayed on the tube. The contents of the line store are modified according to any second type words received during the display period so as to convert the stored data into that for the next line to be displayed.Type: GrantFiled: February 23, 1976Date of Patent: April 11, 1978Assignee: International Computers LimitedInventors: Robert William Laker, Harold Charles Arthur Hankins, Gordon Hughes

Patent number: 4026171Abstract: Work pieces, particularly thin-walled shells of can dimension, are transferred from a magazine at a supply station to another station by a reciprocal shuttle having a pocket for receiving the shells in ready position at the supply station; at the other station, a reciprocal loader transfers the shell laterally from the shuttle to a work station where the work product is produced. The shuttle incorporates a second pocket to receive the work product and includes a surface for gating the supply magazine as an incident to shuttle travel. By locating the path of the shuttle above the path of the loader, it is possible to coordinate shuttle and loader movement for maximum utilization of time. Shells fed to the magazine are constantly aligned inside the magazine to assure effective bottom feed from the magazine to the shuttle.Type: GrantFiled: April 28, 1975Date of Patent: May 31, 1977Assignee: American Can CompanyInventors: Edward Frank Kubacki, Harold Charles Lemke, George Alan Schmidt, Vance Burton Gold, Harold James Jessogne
