Abstract: Abstract of the Disclosure This invention is directed to the preparation of ZrO2 bodies partially stabilized through the inclusion of 0.5-10% Y2O3 with 1-10% of a secondary stabilizer selected  from the group of MgO,  CaO,  CuO,  ZnO,  and CeO2.  The method comprises sintering a shaped batch at 1600°-1800°C,  quickly cooling  the  sintered  shape  to 1000°-1475°C,   holding   said   shape   within   that temperature range to cause precipitation of tetragonal ZrO2  as  islands within cubic ZrO2 grains,  and then cooling  to  room  temperature.   The  final  product exhibits  a  microstructure  consisting  essentially  of about 50-70% cubic ZrO2, greater than 20% and up to 50% tetragonal ZrO2, and less than 10% monoclinic ZrO2.

Abstract: Abstract Method for Measuring Nuclear Magnetic Resonance For recording NMR tomograms according to the 2D-FT method, a CPGM sequence is used for the excitation of the sample and the phase-encoding gradient Gx is modified after every 180° pulse of the CPGM sequence so that every echo signal corresponds to a different projection of the sample. The gradient fields used in the recording are established, regulated adjusted according to intensity and duration in such a way that the Gill-Meiboom requirement constantly is satisfied. Thereby, in the extreme case, it is possible to construct a complete image with a single excitation, whereby the time required for constructing such imagesis reduced to a fraction of the time needed up until now.

Abstract: ABSTRACT OF TOE DISCLOSURE           An apparatus and method for controlling the operating temperatures and differential temperature of a curie effect temperature sensing switch is disclosed.          The temperature switch is adapted to provide temper-ature control of a cold plate in a reagent refrigerator.          The temperature switch activates cold plate cooling devices when the cold plate temperature is above a first operating temperature and deactivates the cold plate cooling devices when the cold plate temperature is below a second operating temperature.  An electron magnet is fixed external of and relative to the tempera-ture switch so that the strength of the external magnetic field sets the operating temperatures of the temperature switch.  A potentiometer is used to incrementally vary the current supplied to the electromagnet to thereby incrementally adjust the strength of the external magnetic field and the operating temperatures.  A micro-processor may be provided to adjust the voltage supply of the potentiometer, which allows remote control of the operating temperatures.  A second potentiometer is connected to the electromagnet so that it incrementally adjusts the current passed to the electromagnet as a function of whether the temperature switch is open or closed.  Incremental adjustment of the second potentio-meter provides incremental adjustment of the temperature differential.  A monitor provides a warning signal if the temperature switch does not open and close within a predetermined time interval.

Abstract: Abstract of the Disclosure A viscometer (10) employs a tube (12) with a check valve (30) at one end and a ferromagnetic bobbin (16) disposed inside and freely movable with respect to it. pair of coils (38 and 40) are alternately energized, causing the bobbin (16) to move against fluid in the tube in one direction, in which the check valve (30) prevents fluid flow, and in the other direction, in which the check valve (30) permits fluid flow within the tube.          When the bobbin (16) moves in the direction in which the check valve (30) permits flow, it draws a new sample of fluid into the tube, and the time required for the bobbin (16) to move in the other direction, in which fluid flow is prevented by the check valve (30), is measured as an indication of the viscosity of the fluid.  The position of the bobbin is sensed by measuring the mutual inductance between the coils (38 and 40).  Preferably, the bobbin (16) is of neutral buoyancy so that operation of the viscometer is substantially insensitive to vibration and to orientation with respect to gravity.

Abstract: ABSTRACT OF THE DISCLOSURE          An apparatus for pack cooling flat stock to be retrofitted to a standard cooling bed.  The apparatus includes collecting means having a plurality of stacker arms mounted for movement with respect to the stationary notch bars of the cooling bed between a first, retracted position, in which the arms underlie the notches in the stationary notch bars to permit uninterrupted transport of bar stock across the bed, and a second, lifting position in which the arms can lift a flat bar to a height sufficiently above the uppermost travel of the moving notch bars to permit a successive flat bar being transported across the cooling bed to be received in the notch of the stationary bar just vacated by the  flat bar lifted by the stacker arms.  Upon the return of the stacker arms to their first position, the flat bar held thereon will be placed on top of the newly-introduced flat bar to form a stack, resulting in a retarded cooling rate for the flat bars in the stack. The lifting and stacking operations may be performed as often as desired to obtain a stack of flat bars of the desired height, whereupon the stacker arms may be returned to their first position to permit the stack to be transported across the bed.

Abstract: ABSTRACT OF THE DISCLOSURE          A compression and a decompression algorithm resides in a memory of a data processing system.  The data processing system communicates to another data processing system via an input/output means and a telecommunications network.  When a message, to be communicated to the other data processing system, is ready for transmission, the data processing system compresses the message data.  A processor or the data processing system compresses the data using the compression algorithm stored in the memory of the data processing system.  The compression algorithm: identifies a mask character in the data representing the most frequently occurring character in the data, develops a mask byte in association with the mask character, the mask byte identifying the locations of the mask character in the data and identifying the locations of each portion of a residual message associated with the data, and develops the residual message, the residual message representing the message data with the mask character extracted from the message data.
