Abstract: A feed roller primarily for feeding crop into a feeder house of a combine harvester is located above and behind a feed draper and includes an outer flight and retractable fingers for feeding the crop through the zone behind the draper and into the feeder house. The fingers rotate about a finger axis offset from the roller axis so that they extend to a maximum at the draper and are retracted behind the roller to release the crop. When the roller is reversed to release a blockage, the fingers are also reversed in direction and the finger axis is moved rearwardly to the opposite side of the roller so that the fingers are extended behind the roller at the feeder house and retracted at the draper. This movement is done automatically on reversing the roller and uses power from the reversal to move the finger axis using a clutch. An anti-distortion wheel is mounted on the finger shaft to prevent retraction of the finger ends into the roller which can cause damage by loss of proper guidance.

IPC: G01S19/22
Filed: 1996-05-24
Granted: 2010-04-13
Abstract: A technique for minimizing or eliminating the effect of multipath signals in a receiver processing pseudorandom (PRN) code signals, such as in a global positioning system (EPS) receiver. The presence of multipath signals adversely affects both code measurements and carrier phase measurements of received PRN signals. One aspect of the invention provides for improved code tracking in the presence of multipath signals, by sampling the received code with a multipath mitigation window (MMW) (FIG. 25D) that results in a code error function (FIG. 25F) that reduces or eliminates the multipath effects. The MMW, which may by any of a number of preferred waveforms (FIGS. 35b-35E), provides a code error function that varies in opposite directions from zero at a desired tracking point (402), but assumes a nearly zero value when the MMW is advanced from the tracking or synchronization point by more than a small fraction of a code chip. Because of this nearly zero code error value on the early side of the desired tracking point, delayed multipath signals will have a corresponding code error function that is nearly zero (FIG. 25F) at the desired tracking point of the directly received signals, and the multipath signals will, therefore, have little or no effect on the desired tracking point and on code synchronization. The effects of multipath signals on carrier phase measurements are minimized by sampling the received signals, together with their possible multipath components, before and immediately after cede transitions (vectors A and B respectively). The vector relationship of the directly received (D) and multipath (M) signals is such that performing a vector average of the two types of samples (A and B) produces the directly received signal (D) and its correct phase, with many, if not all, of the multipath components (M) eliminated.

Title: Methods of fracturing a subterranean formation using a ph dependent foamed fracturing fluid
Inventor: CHATTERJI JITEN
IPC: C09K8/70
Filed: 2004-10-11
Granted: 2009-06-02
Abstract: Methods of fi-acturing a subterranean formation include providing a ftacturing fluid having a first pH. The fracturing fluid may be made by combining a gelling agent, a surfactant, and a proppant. The surfactant is capable of facilitating foaming of the fracturing fluid at the first pH and defoarning of the fi-acturing fluid when its pH is changed to a second pH. The methods of fracturing the subterranean formation further include foaming the fracturing fluid having the first pH and subsequently purnping it to the subterranean formation to fracture the formation. The pH of the fracturing fluid changes to a second pH, for example via in situ contact with an acidic material, causing the level of foam in the fracturing fluid to be reduced. As a result of the reduction of the foam, the fracturing fluid deposits the proppant into the fractures formed in the subterranean formation.
