Abstract: An adjustment mechanism for a rock crusher has an insert installed in the thread form of a bowl support and a locking ring.      A bowl is threadably installed in the bowl support and lock ring assembly and is movable toward and away from a cone assembly. The insert is of a material that differs from that of the bowl and bowl support. The lock ring is movable to fractionally lock the thread forms of the bowl and bowl support against each other. The inserts prevent the galling and deformation of the thread forms previously experienced.

Abstract: A method and apparatus for controlling generation of descriptive information, such as dimension generation, relating to creation of a 2-D view of a computer defined graphical model, such as a 3-D model. An option to choose a semi-automatic mode of generation can enable a user to interrupt generation and rework data being transferred from the 3-D model to the 2-D view. One embodiment provides a user with manual control of dimension and constraint generation such that the process can move from one step to the next, under a user's control. In another embodiment, a semi- automatic mode of operation provides a pause in the generation process. During the pause, the user can rework drawing data or halt the process to perform other tasks. In the absence of an interruption, the system can proceed to a next item of drawing data.

Abstract: Devices and methods for controlling and monitoring the progress and properties of multiple reactions are disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injecting liquids into the vessels at a pressure different than ambient pressure. In situ monitoring of individual reaction mixtures provides feedback for process controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight. Computer-based methods are disclosed for process monitoring and control, and for data display and analysis.

Title: Downhole pump with bypass around plunger
Inventor: FISCHER CHARLES K JR
IPC: F04B47/02
Filed: 2000-06-23
Granted: 2003-12-09
Abstract: The downhole pump has a barrel with a reciprocating plunger therein.   The barrel has a first one-way valve, while the plunger has a second one-way valve. A barrel chamber is formed between the two one-way valves. The barrel chamber expands when the reciprocal movement between the plunger and the barrel is an upstroke movement and then contracts when the reciprocal movement is a downstroke movement. A bypass channel is provided between the barrel and the plunger so as to provide communication around the plunger and its one-way valve. The bypass channel is open when the reciprocal movement is near an end of the upstroke movement. When open, pressure across the plunger can equalize and gas inside the barrel chamber can vent around the plunger and/or pressure can equalize across the plunger one-way valve so as to prevent gas lock and minimize stress on the sucker rods. The bypass channel can be provided by reducing the diameter of the lower end of the plunger, increasing the diameter of the upper end of the barrel, putting grooves in the plunger or the barrel or by making the barrel out of two sections, namely a lower section and a wider upper section and providing holes in the lower end of the plunger below the plunger one-way valve.

Granted: 2005-04-12
Abstract: The present system counteracts the distorting effect of a bi-directional print head by reducing the visual effect of a satellite drop displacement when the print head is traveling in a direction that increases the satellite displacement from a main drop. The system can also counteract the distorting effect of the bi-directional print head by increasing the visual effect of a satellite drop misplacement when the print head is traveling in a direction that decreases the satellite misplacement from the main drop.   The satellite drop displacement can be adjusted by correcting a measured ink temperature, and thereby, an amount of pre-pulsing prior to ejection of the ink.

Abstract: A vibratory impact tool for loosening downhole stuck objects in oil or gas wells, utilizing an internal piston spring which is repeatedly compressed by hydraulic pressure, and repeatedly released by lifting a dart valve from a valve seat on a flow-through piston. When the dart valve is lifted from the valve seat by a tripping spring, flow resumes through the piston, quickly lowering hydraulic pressure above the piston, allowing the piston spring to sharply drive the piston against the housing.  The dart valve is then reseated on the valve seat, causing the piston to again be driven against the piston spring, rapidly repeating the process.

Abstract: A plurality of autonomously controlled valves and pumps in a fluid distribution system are interconnected by a data communication network. The system also includes fluid flow sensors which report to the system by way of the network. The autonomous controllers include information as to their neighbors or environment sufficient to determine malfunctions such as a leak or break in an associated path, or flow-related problems, and can take autonomous action. The actions are established by the autonomous controllers regardless of the existence of a connection to the network, so that even if the network connection fails or is damaged, the valve or pump can still respond with predetermined "intelligent" actions.(118)
