Abstract: Corrosion protection systems which make use of a barrier (2) which is placed between a corrodible substrate (3) and a counter-electrode (2). The barrier can provide more uniform current distribution on the substrate, and/or enable the counter-electrode to be more easily maintained or replaced, and/or reduce the rate at which the current density on an elongate electrode changes with distance from the power source, and/or provide a controlled environment around the electrode to improve its efficiency. <IMAGE>

IPC: A61B5/00
Filed: 1987-08-17
Granted: 1993-04-07
Abstract: Under the present invention, a method and apparatus are provided for compensating for the effect temperature variations have on the wavelength of light emitted by the oximeter sensor light sources (40, 42). In pulse oximetry, LEDs (40, 42) are typically employed to expose tissue to light at two different wavelengths. The light illuminating the tissue is received by a detector (38) where signals proportional to the intensity of light are produced. These signals are then processed by the oximeter circuitry to produce an indication of oxygen saturation. Because current oximetry techniques are dependent upon the wavelengths of light emitted by the LEDs (40, 42), the wavelengths must be known. Even when predetermined combinations of LEDs (40, 42) having relatively precise wavelengths are employed, variations in the wavelength of light emitted may result. Because the sensor (12) may be exposed to a significant range of temperatures while in use, the effect of temperature on the wavelengths may be significant. To compensate for this effect, a temperature sensor (50) is included in the sensor (12) to produce a signal indicative of sensor temperature. This signal is interpreted by t he oximeter circuitry including, for example, a microcomputer (16), where the effect of temperature on wavelength is compensated for. In a preferred arrangement, this compensation takes the form of a computation of an alternative calibration curve from which the oxygen saturation is indicated, given a particular processing of signals from the detector (38).

Abstract: The sealing system consists of a commercially-available shaft seal (2), on the outside of which is pre-arranged a covering ring (3) in order to protect the shaft seal from dirt and from exposure to the atmosphere. This is achieved by the fact that the covering ring (3) pre-arranged separately outside the conventional flexible shaft seal (2) is made of a material which is specially suited for dry running, having high strength values and low internal damping, and is designed with a Z- or S-shaped intermediate wall (6) which has a radially elastic action. It is so designed that the seal gap (8) is covered, on the side exposed to contamination first by a scraper lip (12) applied, like a piston scraper ring, by radial preloading, on the outside and then by a cylindrical jacket region (10) of a guide ring (16), so that the lip (12) can follow the eccentric movements of the rotating machine part (1) virtually without additional distortions. The guide ring (16), which is fitted later directly axially in relation to the scraper lip (12) is designed with a cylindrical jacket region (10) of the same high-strength material and is rigid in the axial direction. The cylindrical jacket region (10) of the guide ring (16) surrounds the rotating machine part (1) as closely as possible and thus entrains the scraper lip (12) without any significantly increased distortion or radial deflections even in the event of eccentric or oscillating movements. The radial elasticity of the seal ring during oscillating movements, while avoiding flexible and abrasion-prone materials in the region of the seal gap (8) is thus ensured essentially by using appropriate design expedients, such as axial notches (13, 14), or a thin intermediate wall (6) between the inner guide ring (16) and outer support ring (7), which is held firm against rotation and axial movement, and by the S- or Z-shaped cross-section.

Abstract: The device comprises a geared motor (17) which drives longitudinally, via a ball screw (20) and nut, the central body (22) of a moving element comprising two slides (24, 25) sandwiching the central body (22). The two slides mesh on a common pinion mounted so as to rotate freely in the central body (22). Each slide drives, via a vertical, cylindrical floating pin (34, 35, 38, 39), a control bar (9, 10) linked to a throw rod (7, 8) which is itself linked to a switch blade. The locking of an operating bar (9, 10) is effected at the end of the travel of the central body (22) by the positioning of a floating pin in a locking groove (40 to 43) of a fixed locking plate (30, 31). A mechanical fault in the transmission chain causes a relative displacement of the slides (24, 25) with respect to the central body (22), which displacement is detected by the rotation of the common pinion integrally connected to means (27) for actuating an anomaly-control contact (29).
