Title: Active airflow system for development apparatus
Inventor: SEYFRIED JOSEPH A
IPC: G03G21/10
Filed: 1992-09-01
Abstract: A development apparatus having an active airflow system for generating negative air pressure to create an airflow  out  of  a  developer  housing,  drawing  airborne contaminants  from  the  developer  housing.    A  developer system includes a plurality of developer housings being selectively moved into operative and inoperative positions for development of a latent image on a photoconductive surface.  As each developer housing is moved into and out of  its  operative  position,  an  air duct  is  rotated in response to this movement for interfacing with, or sealing off,  airflow through the housing,  as  appropriate.   An apparatus  of  this  type  is  used  in  a  multi-color electrostatographic  printing  machine  where  successive latent images are developed with different color developer material,  thus  preventing  respective  color  developer materials  from  intermingling  during  the  development process.

Title: Control system for a vehicle window defogger and de-icer
Inventor: KRAWCHUCK DAVID R
IPC: H05B3/84
Filed: 1992-09-25
Abstract: ABSTRACT OF THE DISCLOSURE    A  windshield  heater  control  system  employs  a thermistor to obtain a measure of the temperature of window glass of a vehicle.   This measured value is translated  to digital  form by the analog-to-digital converter in a microcontroller.   The digital value is then compared with a sequence of threshold level values stored in the read only memory of the microcontroller in order retrieve a corresponding count value from which a duration count value indicative of a heating interval duration is derived.  The duration count value is loaded into   a   programmable   count-down   timer   in   the microprocessor which times the desired interval. A power switch connects the vehicle's electrical supply to a resistive heating element formed as an integral part of the window for the heating interval.   The functional relationship between the initial temperature sensed by the thermistor and the duration of the resulting heating interval is predetermined and is characterized by a marked increase in the heating interval duration when the sensed initial temperature is in the vicinity of zero degrees centigrade.
