摘要： The present invention provides ink-jet writing engine modules for use with a compatible hard copy engine module, a hard copy apparatus based thereon, and methods of manufacturing, operation, and use. Fluidic and electronic partitioning for ink-jet hard copy apparatus is redefined. Modular separation of a hard copy engine from a writing engine allows a replaceable writing module containing all of the key elements of the ink-jet writing system based on writing system technology requirements, particularly for those most likely to age or fail as a result of time, frequency of use, or end-user actions. The writing engine subsystem includes: one or more printing modules having print head elements with concomitant ink manifold components and ink flow and pressure regulation mechanisms; one or more ink containers—either permanent, refillable, or replaceable; one or more ink formulations; one or more ink delivery means, such as tubes and valves fluidically coupling the ink containers to the ink manifolds; service station components; and a framework to retain the elements in a unitary module, insertable cassette-like manner. The present invention further provides a hard copy engine compatible with such a writing engine. The hard copy engine does not contain any components requiring direct contact with ink. Ink-wetted components are predisposed to ink-jet technological changes without affecting the electrical interface and the mechanical interface between the writing engine and the hard copy engine.

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.
摘要翻译：描述了传真图像缩放和平滑方法和装置。它们沿着给定的轴缩放接收到的传真图像以增加打印的图像分辨率，同时平滑缩放的图像以减少视觉上令人反感的刻度。它们通过分析相对于具有不同像素计数的相邻接收线的接收图像数据，并且根据预定义的填充规则填充其中的像素来进行，这些预定填充规则也被设计成平滑待印刷的输出图像。应用各种预定义规则来产生中间结果，其中一些或全部由缩放/平滑算法理解以产生最终平滑的，缩放的输出像素图像。优选地，根据这种规则的分析和填充由接收传真机或传真机接收打印机内的混合硬件和固件子系统执行。

摘要： A biocatalytic method for preparing para-hydroxystyrene from para-hydroxycinnamic acid is described. The method uses an enzyme source having para-hydroxycinnamic acid decarboxylase activity to catalyze the decarboxylation of para-hydroxycinnamic acid in a biphasic reaction medium to produce para-hydroxystyrene, which is extracted into the organic phase of the biphasic reaction medium. The method results in a high yield of para-hydroxystyrene due to the decreased exposure of the enzyme source to the inhibitory product. The product is readily recovered from the extractant, or may be chemically derivatized directly in the extractant before recovery.

摘要： This invention relates to a bioprocess engineering solution for a product removal process for use in a biofermentation. The invention discloses a process for withdrawing an aliquot of broth from a biofermentation vessel during at least a portion of the biofermentation, removing biocatalyst and water, chromatographically separating biofermentation products from the withdrawn broth using water as an eluent, and returning the remaining components of the broth back to the biofermentation vessel. Process chromatography permits highly selective separation of the target molecule, preventing feedback inhibition of the biofermentation.
