    摘要： Facsimile image-scaling and -smoothing method and apparatus are described. They scale a received facsimile image along a given axis to increase the printed image resolution therealong, while smoothing the scaled image to reduce visually objectionable ticks. They do so by analyzing received image data with respect to adjacent received lines having disparate pixel counts and by filling in pixels therebetween in accordance with predefined fill rules that are designed also to smooth the output image to be printed. Various predefined rules are applied to produce intermediate results some or all of which are comprehended by the scaling/smoothing algorithm to produce the final smoothed, scaled output pixel image. Preferably such analyzing and filling in accordance with such rules are performed by a hybrid hardware and firmware subsystem within a receiving facsimile machine or facsimile-receiving printer.

    摘要： Economic and efficient process for preparing an oligomer of poly(butylene terephthalate) or an oligomer of poly(butylene isophthalate) from a transesterification reaction mass by using a countercurrent column reactor system wherein the transesterification reaction mass is fed into the countercurrent column reactor and continuously flows downward while simultaneously a heated inert gas stream continuously flows upward to scrub out volatiles from the transesterification reaction mass, thereby yielding from the bottom of the countercurrent column reactor an oligomer of poly(butylene terephthalate) or an oligomer of poly(butylene isophthalate) suitable for use in a polycondensation reaction. Butanediol is recycled throughout the process through an absorber column.

    摘要： In a potentiometric chart recorder, the speed of the chart motor 22 is, in one mode of operation (AUTO) selected by a switch 32, varied between two values in dependence upon the rate of change or slope of the input signal at 10 as detected in a detector 30. The slow speed is obtained by intermittent operation at the fast speed, and during the non-operative periods power-consuming circuitry e.g. 16, 18, 26 is switched off by a switch 40.

    摘要： A cleaning apparatus includes an elongated housing bounding a chamber with a motor disposed therein. A drive shaft is at least partially disposed within the chamber of the housing, the drive shaft being coupled with the motor such that during selective operation of the motor the drive shaft is rotated continuously. A brush head having a scrubbing element is removably coupled with the drive shaft such that rotation of the drive shaft facilitates rotation of the brush head.
