Abstract: ABSTRACT OF THE DISCLOSURE            A shredding machine of the general type employed for comminuting difficult to shred material incorporates a torque cushioning device for the purpose of minimizing breakage of the comminuting teeth or knives of the apparatus when the teeth encounter metal or other objects which impose a torque overload on the rotating teeth.  The drive motor is coupled to the shafts carrying the comminuting teeth by means of a drive transmission assembly such as a speed reducer box.          The transmission assembly is shaft mounted upon the input shaft to the comminuter so that the casing of the transmission assembly can rotate relative to the fixed frame of the machine about the axis of its supporting shaft.  An arm fixedly mounted upon the casing is biased by springs mounted upon the machine frame.  Application of a torque overload to the com-minuting shafts, as by the teeth engaging a hard metal object, produces a reaction tending to rotate the transmission cas-ing relative to the frame, this rotation being resiliently resisted by the springs to cushion the impact on the teeth.

Abstract: ABSTRACT    A light collector includes a light sampler for gathering light and a light receiver for receiving the light gathered by the sampler and for transmitting it to a system such as a light illumination control system.  The output of the light collector varies with the intensity of the light gathered by the light sampler and can be increased or decreased for a given gathered light intensity by adjusting the distance between the light sampler and light receiver.  Accordingly, if the light collector is used to provide to a light illumination control system the actual light intensity of the area in which light illumination is controlled, the light intensity maintained by the control system can be adjusted by increasing or decreasing the output of the collector.  Also, the present invention includes a light gathering device for a light collector.  The light gathering device includes a lens having angled portions for gathering light from a broad area.

Abstract: Case No. 04-4272-U.S.          APPLICATION OF                       DONALD A. EVERT                  ANGULAR POSITION SENSOR                          ABSTRACT   A position sensor for sensing the angular position of an oscillatory member includes a magnetic element which is permanently magnetized in a predetermined direction and is mounted as a unitary structural part of the oscillatory member for oscillatory movement therewith.  A Hall plate sensor is positioned adjacent the magnetic element to detect changes in the magnetic field presented thereto by changes in position of the magnetic element.  When the magnetic element is oscillated with the transducer, the magnetic field presented to the Hall plate is varied accordingly.  This, in turn, produces an electrical signal as an output of the Hall plate which is a function of the instantaneous position of the magnetic element and hence of the oscillatory transducer.  That electrical signal may then be used to produce synchronization signals for the imaging apparatus.

Abstract: Abstract of the Disclosure An input sampling sequence with an input sampling rate is translated into an output sampling sequence with a selectable output sampling rate in a sampling filter.  A circuit for forming the time difference of the sampling points forms from the given input sampling rate and the desired output sampling rate a signal corresponding to the time difference and  this is used in a translation circuit for converting into data for characterizing the filter coefficients.  The sampling filter is conditioned by the selected coefficients from the translation circuit.  The invention is suitable for the transmission of sampled data, particularly sampled rates between two systems operating at different clock frequencies.

Abstract: DATA PROCESSING APPARATUS HAVING ALTERABLE       INTEREST RATE MODE CAPABILITY     ABSTRACT     A data processing apparatus  (100)  having preprogrammed functions for calculating interest rate dependent variables employs an interest rate mode designation command (130) to enable operation in a-selected one of a set of interest rate modes.  In the preferred embodiment actuation of an AEC key (130) advances the interest rate mode in a circularly sequential manner among annual percentage rate (107)  (sometimes referred to an annual nominal interest rate), annual effective interest rate (108) and annual continuous interest rate (109).  In the preferred embodiment actuation of a key sequence including a compute key (123) and the AEC key enables conversion of an interest rate specified in a first mode into an interest rate specified in the next sequential mode.  The data processing apparatus includes a means for outputting an indication of the current interest rate (107, 108, 109).  A further embodiment enables entry of separate numbers of annual payment periods (131) and annual compounding periods (132) for use in the preprogrammed interest rate dependent functions.

Abstract: Abstract A method of preparing a storage-stable one-part reactive liquid thermal curing polymeric coating composi-tion from an isocyanate-functional polymeric compound which has a substantial portion of its isocyanate groups masked with an isocyanate masking agent, and a crosslinking agent which is substantially insoluble in aprotic solvents.          These liquid compositions are homogeneous even when free of solvents.  Preferably the crosslinking agent is a crystalline polyol.  The method involves the synthesis of a solubilizing oligomer which is formed by the partial reaction of the crosslinking agent and the unmasked isocyanate-functional polymeric compound.  The thermal curing of these compositions results in polymeric coatings which possess superior physical properties.  These cured coatings are particularly useful in the manufacture of retroreflective sheeting.

Abstract: ABSTRACT OF DISCLOSURE       Bituminous froths, typically obtained from the known Hot Water Method of extraction treatment of oil sands, are processed to remove water and part of the coarse mineral solids contained in the froth.  In the process, the froth feed stock from the Hot Water Method treatment is mixed with a naphtha diluent, preferably naphtha which is derived from upgrading or refining of separated bitumen, in preferably the minimum amount sufficient to effectively remove all water by azeotropic distillation, while providing a workable feed viscosity.  The mixture of naphtha and froth is treated to remove coarse solids and part of the water in a settling device, heated to a temperature sufficient to cause vaporization of the naphtha and remaining water as an azeotrope and flashed to substantially separate all water and naphtha from the bitumen.  The dry bitumen with remaining solids, is normally not suitable for passing to a refinery but rather is sent to upgrading at a typical oil sands mining upgrading complex.  Naphtha is recovered and recycled.  The naphtha, in addition to its azeotrope forming feature, makes the froth more homogenous, less viscous, easier to handle and less fouling in heat exchangers, facilitates separation of coarse solids, and eliminates severe foaming when the froth is heated.
