Abstract: A measurement tool for use in pneumatic percussion drilling comprises a body comprising one or more measuring instruments positioned in a drill string above a pneumatically operated hammer of the drill string.

Abstract: A damper apparatus for use in pneumatic percussion drilling comprises a body having one or more damper apparatus supporting a measuring instrument. Each damper apparatus dampens shock/vibration from the pneumatic percussion drilling that is experienced by the measuring instrument.

Abstract: An optical device includes a first optically dimmable switch for providing a first transmittance while the first optically dimmable switch is in a first state and providing a second transmittance distinct from the first transmittance while the first optically dimmable switch is in a second state distinct from the first state. The optical device also includes a dynamic heat source thermally coupled with the first optically dimmable switch. The dynamic heat source is at a first temperature at a first time and is at a second temperature distinct from the first temperature at a second time mutually exclusive from the first time. The optical device may operate as an optical dimming device, which may be used in head-mounted display devices or as dimmable windows or shutters.

Abstract: The present technology is directed to processes for conversion of synthesis gas in a tubular reactor to produce a synthetic product that utilizes high activity carbon monoxide hydrogenation catalysts and a heat transfer structure that surprisingly provides for higher per pass conversion with high selectivity for the desired synthetic product without thermal runaway.

Abstract: A method of forming a sensor for sensing a physical property of a media. A substrate is provided having circuitry thereon including at least one electrical contact and a die is provided having disposed thereon corresponding electrical contacts and a sensing element for sensing a physical property of a media applied to said sensing element. One or more bonding ring or portions are arranged on the die. The die electrical contact(s) and bonding ring(s) can be bonded substantially simultaneously, with conductive bonding material, to the corresponding substrate electrical contact(s) and a surface of said substrate, respectively, to thereby form a sensor. The bonding ring(s) form a pressure seal. The substrate can include corresponding bonding ring(s). The die can include an ASIC for compensating temperature effects on said pressure sensor.

Abstract: A medical image viewing apparatus and method. In one embodiment, the apparatus is a light box assembly for viewing medical film media. The light box assembly includes an enclosure with a translucent viewing panel, at least two light emitting diodes disposed within the enclosure adapted to illuminate the viewing panel, and a controller controlling the color of the at least one light emitting diode. In a second embodiment, an apparatus is provided for displaying a digital x-ray image. The apparatus includes a display adapted to display the x-ray image and a controller in communication with the display for controlling the color of the displayed x-ray image. The controller includes a continuous color palette by which a color can be selected by a user and the color of the displayed x-ray image is changed responsive to the user's selection of the color.

Abstract: A machine tool for mounting on a lateral or console unit of a transfer machine comprises a spindle unit, drive elements, a number of processing spindles, and a tool exchanging device having a tool support for the receipt of used and new tools, which is movable from a charging position into an exchange position in front of the processing spindles. To improve the removal and charging possibilities for the tools, the tool support is moved from its charging position at the rear of the machine tool over the spindle unit and associated drive elements into the exchange position in front of said processing spindles.

Abstract: The invention concerns a transfer line with at least one work station for machining workpieces, which can be advanced intermittently by a timed drive, and with a substantially U-shaped return line connected at its respective ends to two transfer stations, upon which line workpieces, clamped on a workpiece-carrier, can be slidably conveyed along a slideway by a transporting device.
