Abstract: A sensor (20) for measuring the oxygen saturation of blood flow within the skull is described. In a first embodiment the sensor comprises a photodetector (24) and a pair of light emitting diodes (22) surface mounted near the end of a length of flexible printed wiring. The sensor is hermetically sealed by a coating of rubber or polymeric material (30) which has an optical window over the photodetector and light emitting diodes. The sensor is inserted through a burr hole (12) drilled in the skull and slides between the skull and the dura (16) of the brain. The light emitting diodes are pulsed to illuminate blood within the dura and brain with light, and light reflected by the blood is received by the photodetector and converted to electrical signals. The signals are processed by a pulse oximeter to provide an indication of blood saturation. In a second embodiment the photodetector (24) and light emitting diodes (22) are mounted at the end of a core of compressible foam (52) extending from the end of a hollow bone screw (40). As the bone screw is screwed into a burr hole in the skull the photodetector and light emitting diodes will contact the dura and the foam will compress to maintain optical contact between the electrical components and the dura. Light from the diodes is reflected by blood in the dura and brain, received by the photodetector, and the resultant electrical signals are processed by the pulse oximeter.

Abstract: The thermal isolation apparatus for the protruding probe (16) of a biomedical thermometer (10) includes an insulative air gap and a heat sink (20) disposed between the surface of the probe and the optical path through the probe. The heat sink surrounds the optical path, such as a waveguide (18), and acts to evenly distribute any heat along the entire length of the waveguide to avoid temperature variations. Additionally, the heat sink has sufficient mass for high heat capacity and may slow the progress of any heat from reaching or leaving the waveguide until after the measurement by the biomedical instrument has been completed. Disposed over the heat sink is a boot (24) which forms the closed air space between the heat sink and the outer probe surface. The air gap combined with the heat sink provide relative thermal isolation of the optical path through the probe and provide relative thermal isolation of the target anatomy from the temperature of the probe.

Abstract: The invention relates to a telephone handset designed as a directional microphone with a cardioid-shaped or hypercardioid-shaped directional characteristic. The directional microphone comprises an electrodynamic plunger-coil transducer with an acoustic phase-rotation component connected to it, where the plunger-coil transducer is housed in a handset designed as a double shell. The electrodynamic plunger-coil transducer (4) is a sound receiver with a primarily figure-of-eight-shaped directional characteristic and the acoustic phase-rotation component connected to it which serves to generate the cardioid-shaped or hypercardioid-shaped directional characteristic is a constituent part of one or both housing shells (1, 2) of the handset. The acoustic phase-rotation component contains the required acoustic elements, such as acoustic masses (12, 17, L3, L4), compliances (13, 16, C3, C4) and frictions (12, 19, R3, R4). A channel (17) having acoustic mass, with a cross-section of any design, which may also be a small tube, leads with one of its two apertures into the free sound field, and this one aperture (18) passes through the handset housing at a distance from the speech inlet aperture (Fig. 1, 2, 3, 4, 5). <IMAGE>

Abstract: Synthesis gas production comprising primary catalytic steam reforming (20) a first stream (c) of desulphurised hydrocarbon feedstock, optionally followed by secondary reforming using an oxygen-containing gas, and then cooling; adiabatically low temperature steam reforming (76) a second stream (u) of the feedstock, preferably adding a hydrogen-containing gas (v), and then subjecting the product to partial oxidation (82) with an oxygen-containing gas, and then cooling; and mixing the cooled products. 
     For methanol production, the partial oxidation step pressure may be greater than the primary reforming pressure, and the hydrogen-containing gas is taken from the methanol synthesis loop: if the partial oxidation step is non-catalytic and in the absence of steam, the pre-reforming stage can be omitted. Methanol can be synthesised from the reformed first and/or second streams in an auxiliary synthesis stage at an intermediate pressure before the relevant stream is added to the synthesis loop.
