Abstract: In-vivo shimming is performed by acquiring two NMR images with evolution times differing by     where ω 1 , ω 2 , are the Larmor frequencies of the dominant proton species of the imaged object. A pixel by pixel division of the images yields a third image whose phase is proportional to magnetic field inhomogeneity. The phase of the third image set has periodic discontinuities as a result of the periodicity of the arctangent function used to extract the phase from the image . These discontinuities are removed by taking the derivative of the phase and integrating the product of that derivative and a weighting function where the weighting function has zero wight at the points of discontinuity. Off-center quadratic terms in the inhomogeneity are removed prior to fitting the linear shimming gradients.

Abstract: The invention relates to a turfing, draining and collecting substrate of profiled, compression-proof plastic, which is installed under turfed roof surfaces as a watering and dewatering layer. With the aid of its channel-like profiles, which create in the upwardly open channels collecting-water chambers separated from one another by transverse retaining lamellae, precipitation water is collected until it reaches the upper edge of the transverse retaining lamellae. Bonded to the distance lamellae is a jute textile mat, to prevent the underlying hollow spaces from being filled up by superposed layers. Precipitation water is retained within the interconnected collecting-water chamber system, so that it is available to turfing laid thereon for a greater length of time. <IMAGE>

Abstract: For an electrical balance with a measured value recorder (1...16) to produce a load-dependent measuring signal, with a digital signal processing unit (18), with at least one memory (20) for storing data which is obtained from previous measuring signals, and with circuits or data processing devices which use the stored data to correct the measuring signal of the measured value recorder with a correction value to accelerate the transition response following a change in load and then feed it to a display unit (19), it is proposed that the correction value is calculated by means of a recursive algorithm and that the recursion formula is designed so that the stationary final value of the correction value disappears for all load values. The memory required to calculate the correction values is thereby reduced and any effect on the stationary final value due to correction is thus prevented.

Abstract: It is known to assay an analyte by measuring the reflectance density in the range 320 to 360nm using a reflectometer. The analyte is placed on an analytical element which comprises a reagent layer and a registration layer. However, in some cases the reflectometer used to carry out the assay has a maximum obtainable reflectance density of 1.5 and for some assays the maximum reflectance density generated may be 2.0 at 340nm. Described herein is a blocking dye which has a low absorbtivity band from 320 to 360nm and a high absorbtivity band from 640 to 720nm which can be incorporated into either the reagent layer or the registration layer of the element to improve the precision and dynamic range of the assay.

Abstract: Optical analytical instruments to determine a physical parameter of a fluid, and methods of operation of such instruments, are shown. These employ a source of suitable optical radiation, a detector means, means defining a zone for the fluid, means defining an optical path from the radiation source through the fluid zone to the detector means, and reading and control circuitry. At least two readings of optical energy that has been influenced by the fluid are taken without there having occurred substantial change to the fluid. During one of the readings a filter of known absorbance is included in the optical path so that the respective reading represents a calibration reading. A calibration-value-determining means is constructed first to compare, effectively, the two readings to remove the effect of the fluid from the value of the calibration reading, second, to compare, effectively the residual value of the calibration reading to a known value based on the known absorbance of the filter, and, third, on the basis of the second comparison, to make a calibration adjustment based on values derived while the fluid sample remained unchanged in the fluid zone. Novel software implementations of the determinations are shown. Specific examples of instruments and methods implementing these features shown are a dual lamp, no-moving part in-line spectrophotometer, a no-moving part reflection colorimeter capable of on-line or off-line operation, a scatter or fluorescence detecting implementation and a turbidimeter.

Abstract: A switching architecture interconnecting remote switches to a central processor via standard links which may be set up through any number of intervening switching systems utilizing standard switching procedures. The standard links are ISDN links that may be set up dynamically via switching networks within the switching system or via the public switching network. The fact that an ISDN link goes through a portion of the switching system or the public switching network is transparent to both the central processor and remote switch. Upon detecting that a primary central processor is no longer in control, each remote switch attempts to obtain an alternate path to the primary central processor. If a remote switch is unable to obtain an alternate path to the primary central processor, the remote switch switches to an alternate central processor on the assumption that the primary central processor has failed. Because the paths can be made on directly connected ISDN links, through the switching system, or through the public switching network to either the primary central processor or the alternate central processor, there is a high probability of a remote switch being able to obtain such a path. To place calls switched by the remote switch under control of the central processor, the remote switch and the central processor each execute a plurality of hierarchical call control functions. Utilizing the ISDN protocol, these call control functions initiate and maintain a call through the switching system via the ISDN links. After initiating the call, the remote switch and the central processor establish a transport path on the call. Upon establishment of the transport path, low level call control functions in the remote switch transmit (via the transport path) all signaling and control information for other calls switched by the remote switch to high level call control functions in the central processor. However, the call that is communicating the transport path remains entirely under the control of the call control functions in the remote switch. The high level control functions in the central processor process the information and generate new signaling and control information. In order to control the other calls, this new information is transmitted to the low level call control functions in the remote switch via the transport path. Each ISDN link has a plurality of B channels and a D channel having a number of logical links. The transport path may be established on packetized B channels of the ISDN links communicating the call, on logical links of D channels of the ISDN links communicating the call, or by utilizing user communication facilities associated with the call.
