Abstract: HIGH PRESSURE METAL VAPOR DISCHARGE      LAMPS OF IMPROVED EFFICACY                         ABSTRACT        High pressure discharge lamps containing a fill of mercury and metal halides, having a power input of 250 watts or below and useable for general illuminating pur-poses achieve higher efficacy by developing high end tem-peratures without excessively obstructing the transmission of light and without creating excessive thermal losses through radiation and conduction.  To reduce the obstruc-tion of light, heat-conserving coatings on the lamp ends are preferably omitted and small neck seals are used which serve also to reduce thermal losses.  The lamps are con-structed with an aspect ratio of arc chamber length to diameter from 0.9 to 2.5 and with an electrode insertion factor from 0.1 to 0.6 and operate with a wall loading from 10 to 35 watts/cm2 and with an arc loading from 60 to 150 watts/cm.

Abstract: ABSTRACT An automatic development control for use in an electrophotographic apparatus.  The control comprises a pair of substantially planar members forming a channel therebetween through which developer flows.  One of the members is constructed such that an electrostatic charge pattern is periodically formed on the surface thereof, the charge pattern being developed by the attraction of toner thereto which toner has a charge opposite to that forming the charge pattern.  The member on which the developed charge pattern is formed comprises a uni-form, transparent conducting substrate covered with a transparent insulating layer on top of which is deposited a set of spaced-apart, opaque and electrically conducting fingers.  Thus, said one of the members comprises alter-nate opaque and transparent areas.  By grounding the electrically conducting fingers which are all interconnec-ted and by driving the substrate alternately positive and negative, toner is deposited on the transparent areas during the application of one half cycle of voltage and during the following half cycle the toner is deposited on the opaque fingers and scavenged from the transparent areas.  The optical density of the toner deposit is direct-ly related to the toner concentration in the developer. Said one of the members then forms part of the toner con-centration control.
