Granted: 1981-09-29
Abstract: Abstract of the Disclosure Photoconductive insulating compositions comprising organic photoconductors are described.  Organic photoconductor materials such as p-terphenyl or polyvinylcarbazole are dispersed or dissolved in an electrically insulating binder and chemically sensitized with a polymer having repeating units to which are appended a monovalent chlorendate radical. When employing the aforesaid polymeric chemical sensitizer, acrylic polymers or cellulose nitrates are especially useful as insulating binders for heterogeneous compositions of the subject type.  Or, by omitting conventional binders, the described polymeric chemical sensitizer can function simultan-eously as chemical sensitizer and insulating binder for such photoconductive compositions.  Further, the present polymeric chemical sensitizer is particularly useful with one or more additional chemical sensitizers to yield sensitized compositions with especially desirable properties.           Compositions comprising the polymeric chemical sensitizers of this invention are applied to an electrically conducting support to prepare electrophotographic elements.

The cast iron body is shaped to converge frusto-conically from its inlet to its outlet end and has a plurality of radially inwardly extending webs.  A com-bustion chamber shell is mounted in the inlet end of the cast iron body and has a fuel burner inlet for burning a fuel in the chamber defined by the shell.  A closure wall opposite the fuel burner inlet deflects the combustion gases of the burnt fuel towards the fuel burner inlet where the deflected gases are received in a gas guide chamber.          The shell with the gag guide chamber and a gas collecting chamber adjacent the closure wall at the outlet end of the cast iron body is supported on the webs and defines therewith gas flues leading from the gas guide to the gas collecting chamber.  The gases in the flues heat the water in the casing and condensate tends to form in the bottom region of the tubular cast iron body protruding beyond the end walls of the casing.

The modulars having entrance and exit openings.  The entrance opening of the second modular is placed adjacent to the exit opening of the first so that the dish-carrying baskets can pass between the two hermetically sealed modulars.  An arcuate basket supporting and guiding stationary track extends between the two openings in each of the two arcuate-shaped modulars and provides the only support for the dish-carrying baskets as they pass through the two arcuate-shaped modulars, the space between the adjacent ends of the two arcuate tracks at the hermetically sealed junction between the two arcuate-shaped modulars being such that the basket can freely pass from the arcuate-shaped track in the first modular onto the track in the other.  The baskets are advanced stepwise by a mechanism including an arcuate reciprocating bar having pawls, the bars being reciprocably mounted in the respective modulars for causing the pawls to engage the baskets stepwise for moving the baskets only when the bars are moving towards the exit ends.  The adjacent ends of the two arcuate bars are adjustably coupled by a coupling which is removable from the bars to permit separation of the modulars.

Abstract: ABSTRACT          Method for use with beating apparatus equipped with axially adjustable grinding elements rotating relative to one another and preferably of disc type. The grinding elements are enclosed in a housing and between them is a gap or clearance through which the feed stock is passed while subjected to the pressure obtaining between the grinding elements. The width of this gap or clearance is adjusted while the mill is running by causing a beam of radiation, able to penetrate the feed stock and liquid in the clearance gap far more easily than the material of which the enclosing grinding apparatus is constructed, into the gap itself, the rays of this beam running parallel to the surface of the latter. The radiation beam is captured by a detector which measures the intensity of the rays reaching it as a measure of the width of the clearance gap.
