Granted: 1991-01-15
Abstract: Abstract of the Disclosure Apparatus and a method for its use for reducing discarded pneumatic tires and other large articles of tough, resilient, material into pieces of greatly reduced size, including a series of machines which successively shear and granulate tough, resilient articles into smaller and smaller pieces.  In one embodiment of the apparatus according to the invention two successive rotary shear machines are followed by a granulator.  Pieces are sorted before being sent to the granulator, and oversize pieces are sent a second time through the two shears.  In another embodiment of the invention a single rotary shear apparatus is followed by a pair of granulators which successively reduce the size of pieces of material to smaller and smaller sizes.      Materials are fed to the rotary shears and granulators by conveyors whose speeds are controlled by varying the frequency of alternating current electric power supplied to electric motors driving the conveyors, with the fre-quency being controlled in response to sensing the load imposed on the shears and granulators, so that the shears and granulators are operated at or near their maximum capacity.

Abstract: The stereochemistry of sialylation of an acceptor saccharide to obtain an .alpha. (2-3) or .alpha. (2-6) linkage is controlled to favor the .alpha. anomer by use of an aromatic ester of the sialyl reagent. The resulting intermediate .alpha. (2-3) and .alpha. (2-6) sialylated intermediate disaccharide blocks are useful in the synthesis of antigenic substances which can be used to raise antibodies useful in diagnosis and therapy, and can themselves be used as reagents in various applications.      The preparation of the tetrasaccharide antigens corresponding to the 19-9 and sialyl-X antigens characteristic of malignant tissue illustrates the application of this method.

Abstract: IGNITION SYSTEM DWELL CONTROL  Abstract of the Disclosure A control circuit for developing a digital signal for use in a closed loop dwell control of an electronic internal combustion engine ignition system.  The circuit has a ramp counter and a down-counter.  The ramp counter counts-up clock pulses for a period of time beginning when the primary winding of an ignition coil is energized and ending when primary winding current increases to a sensed current limit value.  When current limit is reached, the most significant bits of the count in the ramp counter are loaded into the down-counter.  The ramp counter is now counted-up and the down-counter is counted-down until the down-counter underflows.  The final or ultimate count magnitude in the ramp counter is equal to the count attained by the ramp counter between energization of the primary winding and attainment of current limit added to a fixed percentage of the count attained by the ramp counter.
