Abstract: A vibration damping device for mounting between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. An inner metal cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with the outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to the other portion of the vehicle. An outer housing surrounds a portion of the inner housing and forms a fluid transfer duct or flow channel between fluid chambers formed on opposite sides of the piston within the piston chamber. An electrode is mounted in the fluid duct for applying a voltage across the duct to affect the viscosity of an electrorheological (ER) fluid flowing therethrough to increase the damping force of the device. The electrode includes a plurality of circumferentially spaced splines and intervening grooves extending longitudinally along the fluid duct. The bottom portions of the grooves have a decreased electric field applied thereto than the splines, providing bleed grooves or leak paths for the ER fluid to decrease the shear-rate of the fluid. The inner housing may be formed with elongated projections which extend into the grooves of the electrode to provide a more uniform electric field along the fluid duct to control the amount of leakage through the bleed grooves. A secondary electrode ground may be formed in the grooves to control the electric field in the bleed grooves.

Abstract: Abstract An effective non-intrusive data-based monitoring method may reduce the cost of control loop performance maintenance by screening and short-listing those control loops or valves that need maintenance. The invention comprises a data-based, model-free, non-invasive method that can automatically detect and quantify stiction present in control valves. The method does not require the implementation of any additional valve travel test or, as commonly known, bump test of the control loop. The method may detect and quantify stiction using controlled variable (pv), controller output (op) and set point (sp) data. It does not require valve positioner (mv) data.

Granted: 2009-12-01
Abstract: The invention concerns a drop mass soil compaction apparatus (10, 50) which has a supporting frame (12,64) and a mass (20, 76) which can be raised relative to the frame to an elevated position above a soil surface (40, 61) which is to be compacted. The apparatus includes a mass lifting arrangement for raising the mass to the elevated position such that when the mass is subsequently dropped from such position it impacts on the soil surface in order to compact it. The mass lifting arrangement includes a flexible cable (24, 92) attached to the mass and an hydraulic or pneumatic actuator (36, 68) which is carried by the supporting frame and which acts on the cable in a manner to raise the mass. The cable effectively isolates the mass lifting arrangement, and in particular the actuator, from shock loads generated by impacts of the mass on the soil surface.

Abstract: Disclosed is a process for producing light olefins from hydrocarbon feedstock.  The process is characterized in that a porous molecular sieve catalyst consisting of a product obtained by evaporating water from a raw material mixture comprising a molecular sieve with a framework of Si-OH-Al- groups, a water-insoluble metal salt, and a phosphate compound, is used to produce light olefins, particularly ethylene and propylene, from hydrocarbon, while maintaining excellent selectivity to light olefins. According to the process, by the use of a specific catalyst with hydrothermal stability, light olefins can be selectively produced in high yield with high selectivity from hydrocarbon feedstock, particularly full-range naphtha In particular, the process can maintain higher cracking activity than the reaction temperature required in the prior thermal cracking process for the production of light olefins, and thus, can produce light olefins with high selectivity and conversion from hydrocarbon feedstock.

Title: Brake flush accelerator
Inventor: PETTY JON A
IPC: G05G1/48
Filed: 2006-11-15
Granted: 2010-01-19
Abstract: A Brake Flush Accelerator (BFA) selectively depresses a brake pedal while the master cylinder reservoir is under pressure from a brake flush machine, forcing fluid through the system at a very rapid rate. The BFA also provides a thorough flush as internal hydraulic pressure from the master cylinder can be used to exert force to remove contaminates from the brake system. The BFA  exposes the low/no pressure area of the master cylinder to fluid flow from the pressurized master cylinder. When the brake pedal is depressed, a port in the master cylinder is opened which exposes the low/no pressure area of the master cylinder to fluid flow from the pressurized master cylinder reservoir. The BFA  receives its pneumatic power from an air compressor or is easily adapted to a car tire. The BFA can be powered directly from the brake flush machine or attached to a vehicle's battery.
