International Classification:

C07D 307/60

US Classification:

549255, 549233, 106238

Abstract:

The invention relates to an aqueous sizing composition comprising (a) an emulsion comprising an alkenylsuccinic anhydride component containing alkenylsuccinic anhydride particles suspended in a first starch component containing emulsifying starch selected from the group consisting of non-ionic starches, ionic starches, and mixtures thereof, and (b) a second starch component selected from the group consisting of non-ionic starches, ionic starches and mixtures thereof, such that the alkenylsuccinic anhydride and the starch in the emulsion and the second starch component are present at a starch: alkenylsuccinic anhydride weight ratio that is sufficiently high to enable the sizing composition to impart useful sizing properties to a fibrous substrate when the sizing composition contacts the fibrous substrate. The invention also relates to fibrous substrates treated with the sizing composition, processes for making the composition and processes for using such a composition, and other compositions. In one embodiment, alkylene ketene dimer is used instead of alkenylsuccinic anhydride.

Abstract:

A computer-implemented method for performing stability analysis for a digital motor controller includes receiving a reference signal to be injected into a digital speed control loop and controlling, by a hardware description language (VHDL) component, the injection of the reference signal into the digital control loop through a field programmable gate array (FPGA) hardware interface. The method also includes providing the reference signal to the digital speed control loop to determine a performance of the digital motor controller and receiving a feedback signal, at the FPGA hardware interface, from the digital speed control loop based on the reference signal. The method includes comparing the reference signal to the feedback signal to evaluate the performance of the digital motor controller and exporting a result of the comparing by the FPGA hardware interface to indicate the performance of the digital motor controller.
