Abstract: Sacrificial use of amino polymers to modify the crystal structure of platinum derived from chlorine compounds in a method to oxidise hydrocarbons, comprising: (a) preparing a polymer modifier by controllably reacting amine with epoxy resin to form a soluble adduct and adding to the adduct a solvent to form a homogeneous amino polymer solution; (b) coating a granular support material with platinum/chlorine compounds; and (c) mixing the coated support material with the polymer solution and heating the mixture to evaporate the solvent and to decompose and eliminate the polymer, leaving the coated granules with platinum in a morphologically changed condition devoid of amino polymer but having enhanced catalytic effectiveness for promoting oxidation of hydrocarbons. The amine is of a primary or secondary amine, preferably the hydroxyethyl group. The epoxy is a soluble resin comprising two or more epoxide groups per molecule, i.e., dihydric phenol or dihydric alcohol. The polymer modifier is preferably a soluble amino polymer having a molecular weight of 500-50,000 and advantageously is 50% or more by weight of the solution.

Title: Methods and apparatus for quantifying tissue damage.
Inventor: YOUNG WISE
IPC: G01N33/48
Filed: 1990-08-13
Abstract: Tissue damage may be quantified, tissue type identified, neural activity monitored or blood hematocrit determined by measuring the difference between the total tissue sodium and potassium concentrations in the area in question. Comparison of these measurements with standard values permit evaluation of the amount of tissue damage in cells of the same type or the tissue type in non-necrotic cells. Evaluation over time of normal brain cells permit monitoring of neural activity. By directly and simultaneously measuring sodium and potassium ion concentrations, for example, a nuclear magnetic resonance spectrometer can image areas of different tissue type in differing colors. In this manner tumors and lesions can be clearly delineated. Measurement of total potassium concentration of a blood sample and the potassium concentration of the cell-free plasma will permit determination of cellular volume fraction (hematocrit).

Title: Process and device for testing a hall sensor system.
Inventor: HAUSSECKER WALTER
IPC: G01R33/06
Filed: 1990-11-14
Abstract: The proposal is for a process for testing a sensor system consisting of a Hall sensor with a digital signal output (20) and a control magnet movable in relation thereto and a Hall sensor as a device for implementing the process. To this end, the magnetic flux density is detected and assessed via an additional analog signal output (19) of the Hall sensor. Besides the digital position signals it is thereby possible by means of a single sensor to achieve self-checking on whether the distance between the Hall sensor and the control magnet is correct and whether digital position signals can still be expected to be reliably generated.

Abstract: A method to minimise noise, in particular in FM reception, due to interferences of the useful signal by a noise signal extracts as noise-specific information from the overall signal received the duration of a dip of given magnitude in the amplitude of the overall signal, caused by the noise signal, in the region of maximum noise phase response and uses this information to correct the overall signal on the output side, at least during the periods of time of maximum interference. In this case, the amount of the threshold value of the received signal at which the correction phase is initiated is individually fixed by the value of this signal (reference level) and by the steepness of the amplitude dip for each interference and consequently the duration of the correction phase is defined as a function of the significance of each interference with regard to its perceptibility. 
<??>The correction of the output signal can be performed, for example, by a blanking-out of the noise signal by means of a sample-and-hold circuit during the duration of the correction phase, or else by interrupting the demodulation of the IF signal in the correction phase.

Abstract: A filter unit (10) for removing particulates from exhaust gases for example from a diesel engine, includes several filter elements (24) arranged so the gras flows through them are in parallel and that no individual element carries more than a fifth of the total flow. Each element (24) comprises a tubular heating element (50) of high voidage electrically conducting material, with a secondary filter layer (52) adjacent to its upstream surface, and with means (53-63) to ensure the gas flow and particulate deposition are substantially uniform over the upstream surface. At intervals the heating elements (50) are electrically energized, in turn, to burn off deposited particulates. At any one time only a subset of the elements (24) is energized through which at that time no more than a fifth of the total gas flow passes. The unit (10) might have thirteen such elements (24), energized one at a time. Alternatively it might have fewer such elements (24) along with a valve to reduce the flow of gas through the element or elements which are at that time being energized.
