Granted: 2010-08-24
Abstract: The invention relates to the synthesis of novel fluorinated elastomers with very low glass transition temperatures (T¿g?), a good resistance to bases, oil and fuels and good working properties. Said elastomers contain hexafluoropropene (HFP), sulfonyl perfluoro(4-methyl-3,6-dioxaoct-7-ene) fluoride (PFSO¿2?F), vinylidene fluoride (VDF) and/or at least one fluorinated alkene and/or at least one perfluorinated vinyl ether. In particular, said elastomers can be produced by radical copolymerisation of HFP and PFSO¿2?F or by radical terpolymerisation of HFP, PFSO¿2?F and VDF in the presence of different organic starters, for example, peroxides, peresters or diazos.

Title: Heated enclosure purge system
Inventor: NIMBERGER SPENCER M
IPC: F17D3/10
Filed: 2002-09-17
Granted: 2010-01-19
Abstract: A combination purging system and sampling system is provided for sampling gas from a pipeline. A flow path 40 provides fluid communication between a sample bottle 45 and the pipeline. The sample bottle 45 is initially filled with an inert gas for purging air from the flow path 40 and venting to atmosphere. A supply valve 46 controls flow between the pipeline and the flow path 40, and a bleed valve 35 controls venting from the flow path 40 to atmosphere. The relationship and positioning between the valves and the flow path prevents condensation from entering the sampled gas while purging and sampling.

Title: Apparatus and method for reproducibly modifying localized absorption and scattering coefficients at a tissue measurement site during optical sampling
Inventor: ACOSTA GEORGE
IPC: A61B5/00
Filed: 2001-07-09
Granted: 2008-09-16
Abstract: An apparatus for varying localized absorption and scattering coefficients at a tissue measurement site in a controlled and reproducible manner during optic al sampling of a tissue volume by controlling the pressure applied to a tissue measurement site by a spectroscopic analyzer allows applied pressure to be maintained at a constant level, or the applied pressure may be varied in a controlled, reproducible manner as a function of time. A rest for receiving a body part holds the body part in a fixed position and at a fixed elevation. A mechanical system advances a fiber optic probe until it makes contact with t he body part with a constant amount of pressure. The applied force is supplied by a counterweight on a single arm balance. A temperature control allows the temperature of the fiber optic probe to be equilibrated with the temperature in the immediate vicinity of the tissue measurement site. Alternate embodiments allow the fiber optic probe to be brought into direct contact wi th the tissue measurement site, and displaced a known distance into the tissue. The invention is also embodied as a method in which the absorption and scattering coefficients for successive spectral measurements are calculated to determine optimum depth of penetration for detection of a target analyte.</S DOAB>

Title: Counter-balancing mechanism
Inventor: LAWRENCE JEFFREY
IPC: F16M11/10
Filed: 2002-02-08
Granted: 2012-01-31
Abstract: A counter-balancing mechanism comprising a support for supporting an article to be tilted about a horizontal axis; a cam movable with the support, the cam surface of which varies in a direction normal to the plane of rotation of the support; and a cam follower loaded by a resilient means whereby, as the support rotates, the cam follower and resilient means causes a return force to be exerted to substantially counteract the torque caused by the rotation of the support. Preferably, a means for varying the return force in accordance with a load on the support is provided, wherein the cam and resilient means is able to rotate about a centre offset from the central axis about which the support rotates and including means for setting a variable reaction point, against which the cam follower force reacts, at or offset from said central axis, thereby to cause the return force exerted due to rotation of the support about a particular angle to be varied.

Abstract: A downlink telemetry system providing improved apparatus and methods for communicating instructions via pressure pulses from surface equipment to a downhole assembly. The apparatus comprises a surface transmitter (6) for generating pressure pulses, a control system (90), and a downhole receiver (21) for receiving and decoding pulses. In operation, a bypass valve (7) is opened and closed to create a series of pressure pulses received and decoded by a downhole receiver (21). The method significantly reduces the time required for downlink communication without interrupting drilling and without interrupting uplink communications such that simultaneous, bi-directional communication is achievable if the uplink and downlink signals are sent at different frequencies. The telemetry scheme and algorithm provide an inventive method for filtering and decoding the downlink signals. The algorithm determines the time intervals between pulse peaks and decodes the intervals into an instruction. The algorithm also includes error checking for verifying that the instruction was properly received downhole.

Title: Radiological image pickup apparatus

IPC: H04N5/335
Filed: 2004-03-01
Granted: 2007-11-20
Abstract: A light application mechanism applies light to the split electrode formation side of a semiconductor layer and an intermediate layer sensitive to radiation in an FPD, and change in the effective sensitive area does not occur, so that fluctuations in the detection sensitivity of the FPD can be circumvented. As light application is continued still after incidence of radiation stops, occurrence of residual output can also be circumvented. Further, a light strength control section controls the light application section so as to increase or decrease the strength of light applied by the light application section in response to a decrease or an increase in a gain setup value of an electric signal processing circuit, and the dark current component narrowing the dynamic range does not widely occupy the output range of the electric signal processing circuit. Consequently, the dynamic range is not largely narrowed either.

Abstract: The invented apparatus is designed for use with a tow vehicle and trailer combination. The apparatus comprises a controller, a vacuum supply sensor, and a sensor unit used to measure the barometric pressure and/or elevation of the current location of the tow vehicle/trailer combination. Using information from the sensor unit, the controller determines a vacuum pump activation level and/or deactivation level appropriate for the ambient pressure in which the apparatus is operating. By monitoring the signal supplied by the vacuum supply sensor and by operating a vacuum pump switch signal, the controller maintains a supply of vacuum between the activation and deactivation levels. In this manner, the controller can compensate for changes in local conditions so as to operate the vacuum pump in an efficient manner while maintaining an adequate supply of vacuum for operation of the trailer brake system.
