Title: Method and an arrangement for accurate digital determination of the time or phase position of a signal pulse train
Inventor: DENT PAUL W
IPC: G01R25/00
Filed: 1990-03-28
Abstract: The invention relates to a method and an apparatus for accurate digital determination of the time or phase position of a signal pulse train in relation to a fixed time or frequency reference. The arrangement generates and produces directly on the output a digital word corresponding to the measuring value current at that time. The pulse train is compared in a plurality of EXCLUSIVE-OR gates (OR0-OR3) with a number of reference clock signals (RCL0-RCL3) which are mutually displaced in time. There is produced on the output of each gate a signal (MS0-MS3) which is dependent on the input signals of the gates with respect to frequency and pulse ratio. The output signals from the gates are sent to a comparison circuit (CO) in which a MIN of MAX operation is carried out, the pulse ratio of the output signals (MS0-MS3) being compared and the output signal which lies nearest to a predetermined pulse-ratio value being subjected to analogue/digital conversion in a converter (AD). The pulse train, in digital form, is thereafter code-converted in a code converter (CC) together with the three most significant bits taken from the pulse train prior to the AD-conversion process. The thus produced binary code can be corrected for systematic deviations resulting from frequency differences between the frequency, reference frequency and/or sampling frequency of the pulse train, by the addition/subtraction of a predetermined numeric sequence.

Title: Ice dispenser conveying means
Inventor: BUCHSER WILLIAM J
IPC: A23G9/04
Filed: 1990-12-05
Abstract: ABSTRACT OF THE DISCLOSURE     An ice dispenser for a refrigeration apparatus comprises a container for storing ice bodies, the container having a front access opening.                A housing at the front access opening has a space for dispensing ice bodies.                An ice conveyor transfers ice bodies stored in the container to this space by means of a wire auger with an inner end rotatably coupled at a rear wall of the container and an outer end, and a rotatable drum dispenser in the housing having a center hub receiving this outer end and being rotatable therewith.  A pair of opposed, helical blade augers extend between the hub and a cylindrical outer wall.          A baffle is mounted outwardly of the drum dispenser and has a planar outer wall with an enlarged opening between the drum dispenser and the dispensing space, the opening being generally arcuate and extending partially about the center of the outer wall, and having a cutoff edge oriented away from this center.                The wire auger and drum dispenser are rotated to deliver ice bodies from the container to the dispensing space  whereby the spacing of the blade auger outer edges and the orientation of the opening cutoff edge prevent ice bodies from wedging between the blade augers and the baffle.

Patent CA-2036389-A1 (CA)
Inventor: BRASEL GREGORY M
IPC: B22F1/10
Filed: 1990-05-25
Abstract: Shaped parts are formed from a powder having the desired chemistry of the finished part by mixing the powder with a thermosetting condensation resin that acts as a binder. The resin may be partially catalyzed, or additives or surfactants added to improve rheology, mixing properties, or processing time. Upon heating, the inherently low viscosity mixture will solidify without pressure being applied to it. A rigid form is produced which is capable of being ejected from a mold. Pre-sintered shapes or parts are made by injection molding, by using semi-permanent tooling, or by prototyping. Binder removal is accomplished by thermal means and without a separate debinding step, despite the known heat resistance of thermosetting resins. Removal is due to the film forming characteristic of the binder leaving open the part's pores, by providing oxidizing conditions within the part's pores as the part is heated, and by insuring that the evolving resin vapor diffuses through the pores by heating the part in a vacuum.

Title: Method for control of a distillation process
Inventor: FUNK GARY L
IPC: B01D3/42
Filed: 1991-02-21
Abstract: Abstract of the Disclosure: A method for automated control of a petroleum distillation column in which signals representing temperatures, pressures and fluid flow rates for selected product streams withdrawn from the column are transmitted to a digital computer where, by means of a programmed algorithm, they are used to derive a true boiling point curve for the petroleum products of such product streams.  The true boil point curve is then used to infer selected properties for the petroleum products which are compared with desired properties for the products of the monitored product streams and the differences between the inferred and desired properties are utilized to adjust automatically one or more of the operating parameters for the column so as to move the column's performance incrementally towards optimization.

Abstract: ABSTRACT OF THE DISCLOSURE           Improved pulse width modulation technique provides for an increased sampling rate without an increased ON/OFF rate at associated control devices.  Both ON/OFF and OFF/ON edges in a PWM signal are modulated.  The system then samples at twice the pulse turn-on rate to provide more frequent sampling.  System response time may be decreased without an increase in the operating frequency for the associated control device.  Particular application of the present invention may be found in continuously variable transmission systems which utilize PWM-controlled electrohydraulic valves for ratio control, line pressure control and clutch control.  A system for implementing the PWM signal has a duty-cycle calculator coupled with timing circuits to control input data reading functions and circuit enabling, leading edge and trailing edge regulators and an output pulse generator.

Abstract: Abstract of the Disclosure:       In an apparatus for carrying out a linear transform calculation on a product signal produced by multiplying a predetermined transform window function and an apparatus input signal, an FFT part (23) carries out fast Fourier transform on a processed signal produced by processing the product signal in a first processing part (21).  As a result, the FFT part produces an internal signal which is representative of a result of the fast Fourier transform.  A second processing part (22) processes the internal signal into a transformed signal which represents a result of the linear transform calculation.  The apparatus is applicable to either of forward and inverse transform units (11, 12).
