Title: Sampling container for collection of fluids
Filed: 2012-03-14
Abstract: A method and apparatus for the collection, transportation and analysis of gas samples which may be required in various scientific, environmental and natural resource contexts is provided. The apparatus comprises a sampling container assembly for sampling a fluid. The container assembly comprises a body defining a sampling chamber having a first end and a second end, a first valve assembly fluidly coupled with the first end and a reactant material positioned within the sampling chamber for reacting with the fluid. After collection of the sample in the sampling container assembly, hazardous fluids are converted to non-hazardous materials that can be transported without additional hazardous material restraints. Further, the flow through design of the sampling container assembly allows for the collection of gases such as H2S at low concentrations by flowing the gas over the reactant materials for longer periods of time.

Title: Method for preventing shield casing catching due to too large frictional resistance in earth pressure balance shield
Filed: 2011-06-09
Abstract: A method for preventing shield casing catching due to too large frictional resistance in earth pressure balance shield is provided. The method involves carrying out real-time monitoring to the earth voltage signal between the shield casing (3) and the stratum (4) through the earth pressure sensor (21, 22, 23, 24) on the shield machine shell. Combined with the known parameter and shield machine geological parameter in construction, related resistance in the shield machine operation is calculated. The frictional resistance F1 between the shield casing (3) and the stratum (4) is calculated by CPU module in PLC according to the voltage signal transmitted by the earth pressure sensor (21, 22, 23, 24). The frictional resistance F1 between the shield casing (3) and the stratum (4) is ultimately determined whether it is less than or equal to the difference between the total propel force Ft of shield machine propel oil cylinder (5) divided by the correction coefficient KXZ and the total resistance F2+ F3+ F4+ F5; if so, the shield machine is normal propulsion; if not, the warning device alarm. The shield machine fault of forced shut down due to shield casing (3) catching is effectively avoided so that the construction risk is reduced and the construction efficiency is improved.

Title: Method and apparatus for ultrasonic non-destructive testing of a metal workpiece
Inventor: PLOEGAERT HENDRIKUS THEOPHIEL
IPC: G01N29/04
Filed: 1980-10-30
Granted: 1984-10-18
Abstract: An ultrasonic testing method in which a hf transmitting/receiving coil (14) and a magnet are moved adjacent the workpiece surface, hf pulses are fed to the coil and the signals induced in the coil are amplified by an amplifier (27) suffers from the disadvantage that the induced signals vary in strength with variation of the distance of the coil from the workpiece. The electromagnetic coupling factor between the coil and the workpiece is monitored, e.g. by measuring the transmission voltage applied to the coil, and the amplification factor of the amplifier (27) is controlled in dependence on the variation of this coupling factor.

Granted: 1984-08-09
Abstract: A method of manufacturing and a use of a compression resistance and high stable surfacing mass for heavy loaded surfaces, especially for strong traffic and heavily loaded street and road sections and mainly comprising a stone material which is bound by an asphalt mass. The surfacing mass is manufactured by heating asphalt at least to the recommended temperature for mixing asphalt with a stone material, and before or after the admixing of asphalt with the stone material a fibre material is added, especially a mineral fibre having an average fibre diameter of between 1  mu m and 5  mu m in an amount of about 0.5-20% of weight in relation to the asphalt weight, and the fibre material is mixed homogenously so as to throughout provide substantially separate fibres in the asphalt phase. When admixing the fibre material before adhesion of the asphalt to the stone material the temperature of the asphalt is preferably increased to 20-40 DEG C above the temperature for mixing the asphalt mass into the stone material, and after a homogenous mixing of asphalt and fibre the asphalt mass is cooled to the said admixing temperature, whereupon the asphalt-fibre mass is mixed homogenously with the stone material.

Title: Pressure-compensated hydraulic positioning system
Inventor: VEALE JOHN PAUL
IPC: G05B19/19
Filed: 1983-12-28
Granted: 1989-05-24
Abstract: A conditioner grinder having a workpiece carried by a car that reciprocates adjacent a grinding wheel. The grinding wheel is supported for movement in a direction both normal to the surface to be ground and transversely across the surface to be ground. Movement of the grinding wheel in both of these directions is through conventional hydraulic actuators. The hydraulic actuator indexing the grinding wheel transversely across the workpiece contains a pair of pressure sensors that measure the differential pressure across the piston of the actuator. The differential pressure signal is subtracted from a position error indicative of the difference between the actual position of the grinding wheel and the desired transverse position of the grinding wheel. In the event that the position error exceeds a predetermined value, a pressure command added to the position error increases or decreases linearly with time toward the position error, thereby providing a steady-state error signal to cancel the signal resulting from a differential pressure across the piston under steady-state conditions.

Filed: 1984-04-11
Granted: 1988-09-01
Abstract: Connectors for terminating and splicing high voltage power cables comprise a metallic tubular sleeve having an open end for receiving an electrical conductor and a closed end. The inner wall of the sleeve is pretinned. The sleeve can be provided with a slug of solder proximate to the closed end. A connection is made by inserting the conductor into the sleeve, heating the solder, and as the solder melts, relatively moving the connector and the conductor toward each. The connector can be provided with an insert to accommodate conductors that are non-circular in cross-section. The connector can be provided with means for pressuring the slug of solder toward the open end of the sleeve at the temperature at which the slug of solder melts. With this connector, no relative movement between the conductor and the connector is required. Merely by melting the solder, the means for pressuring causes the solder to extrude around the conductor.
