Title: Method of testing a xerographic copier
Inventor: CONLY DOUGLAS JARVIS
IPC: G03G15/00
Filed: 1981-08-05
Abstract: In order to test components of a xerographic copier, the copier is run through test cycles in each of which copying stations which act directly on the imaging element are set to abnormal conditions. In one such cycle, during a first period, the exposure lamp is initially on and then turned off. In a further period in the same cycle, erase lamps are selectively turned on and off to produce a test pattern image. Other components which are either turned off at selected periods in a copying cycle or driven with lower than normal voltages include the charging, transfer and cleaning corotrons. In addition the developer bias may be set low. The resulting copy sheets provides an indication of fault conditions within the copier.

Abstract: A retroreflector consists of a support surface 12 coated with a layer 11 of small retroreflecting particles such as glass spheres. The support surface comprises a plurality of regularly repeating, like structural elements 13 which are inclined to the overall plane of the retroreflector The surface elements 13 can be of various shapes and serve to increase the angular range over which retroreflection can occur. The optical characteristics of the proposed retroreflectors can be tailored so that they are eminently suitable for use in certain beam scanning applications such as continuous monitoring of doorways and windows by an optical beam scanning device located at one corner thereof in order to detect, for example, intruders.

Abstract: The previous methods of controlling the flow of vapor transported by a carrier gas from a bubbler (10) to a using system have customarily been the thermal-conductivity mass flow meter and the temperature controlled vaporizer bubbler (10). However, such control methods have the disadvantage that fluctuations occur in the vapor mass flow. 
     In accordance with the present invention the flow of vapor transported by a carrier gas from a bubbler (10) to a using system is controlled to provide on uninterrupted uniform mass flow ofthevaporto the using system. Control of the flow of vapor is achieved by controlling the temperature (48) and pressure (50) within the bubbler (10).

Abstract: A wide travelling web is coated on one side thereof by passing the web through an elongated web coating nip in contact with an elongated pool of non-Newtonian coating liquid. The pool is repienished by a conduit manifold having one inlet conduit (34) and four outlet ports (46, 47, 48, 49). The outlet ports communicate directly with the pool. The inlet conduit divides into two branch conduits (40,41) of equal, uniform cross section, one-half that of the inlet conduit, and of equal length. Each branch conduit divides into two branch conduits, each leading to an outlet port. The four branch conduits (42, 43, 44, 45) are of equal, uniform cross section, one half that of each of the two branch conduits, and of equal length. Each of four liquid flow paths through the branch conduits subjects the coating liquid to substantially identical flow rheology because the paths are of substantially equal length and substantially equal fluid shear characteristic.

Abstract: Das erfindungsgemäße Steuerventil (11) hat zwei elektromagnetisch betätigbare Steuerschieber (13, 14), die unabhängig voneinander betätigbar sind. An jedem Steuerschieber (13, 14) ist je ein Permanentmagnet (35, 36) angeordnet, die in Wirkverbindung mit den Elektromagneten (33, 34) stehen. Die Elektromagnete (33, 34) sind zu den Permanentmagneten (35, 36) gleichsinnig gepolt, so daß die Steuerschieber (13, 14) von den Elektromagneten (35, 36) abgestoßen werden und so in ihre Betriebsstellungen bewegt werden. Da die Spulenkörper (41, 42) aus weichmagnetischem Material bestehen, werden die Permanentmagnete (35, 36) bei Abschalten der Elektromagnete (33, 34) angezogen und so die Steuerschieber (13, 14) in ihre Ausgangsstellung zurückgeführt. Die Öffnungsperiode des Steuerventils (11) ergibt sich durch Überlappung der Öffnungszeiten der einzelnen Steuerschieber (13, 14), die sich bei Ausgangsstellung in unterschiedlicher Stellung befinden, nämlich einer (13) in Öffnungsstellung und einer (14) in Schließstellung. Die Schaltzeit des Steuerventils (11) wird verkürzt, und der Schaltzeitfehler geht nur mit einer Flanke des Schaltens des Steuerventils (11) in das Zumeßergebnis ein.
