Abstract: ABSTRACT OF THE DISCLOSURE             A coke oven door construction, adaptable for either the pusher side or the coke side of the oven, has a diaphragm arranged so as to exert an even pressure all around the door and associated jamb when the door is locked in the jamb by a suitable locking device.  After the door has been locked in place, air is connected to the bottom of the door so as to permit injection of a mixture of air and a suitable anti-stick agent all around the door diaphragm and onto the sealing surface of the associated jamb.  The anti-stick agent keeps carbon and other foreign matter from sticking to the diaphragm and jamb surfaces.  Further, if a fire occurs between the sealing surfaces, it can be extinguished by connecting the air to the doors.  The air mixed with the anti-stick agent is preferably preheated before it reaches the jamb surface so as to prevent warping of the jambs.  In addition, to eliminate vertical warping of the door,the frame fo the door is made flexible in the middle thereof, and the flexible portion of the frame is spirng loaded so as to hold the frame straight until the jamb moves inboard or outboard of the frame.  If the jamb does move, the door seal will move with it keeping the same pressure on the seal at all times.

Abstract: METHOD AND APPARATUS FOR INCREASING     THE SPACING BETWEEN PLANTS IN ACCORDANCE WITH THEIR GROWTH RATE     Abstract of the Disclosure A selected number of troughs containing small plants therein are placed in a parallel relation with each other at one end of a soilless growth chamber.  Tubular screw sections having helical grooves therein are employed for advancing the troughs from the loading end of the chamber to the unloading end thereof, the helical or screw pitch being considerably greater at the unloading or harvesting end in order to accommodate for the increased size of the plants as they reach maturity.  In other words, the pitch of the helix is correlated with the rate at which the plants mature.  Tubular screw sections having different pitches can be substituted when the growth rate differs from one species to another.

Abstract: INSERTED-BLADE CUTTER ASSEMBLY    ABSTRACT       An inserted-blade cutter assembly uses a laterally project-ing finger formed integrally with each removable blade which is engagable with a reference-positioning surface on the cutter body to precisely position the blade. Two locking caps have frustoconical surfaces which engage similarly shaped end portions of the blade members providing a sufficient radial force to counter centrifugal forces and thereby retain the blades in the body member. The lock-ing caps also provide a sufficient axial force to keep the blade finger in contact with the reference-positioning surface to provide precise cutting tooth alignment during the cutting operation. This structure obviates the need for individual fasteners, shrink fits, or adhesives thereby facilitating blade removal and replacement.

Abstract: CHARGE DENSITY CONTROL                      Abstract An electrophotographic copier having a toner concentration control apparatus which periodically effects a toner-patch test cycle during which the optical density of toner deposited on a photoconductor test area is measured, as by light reflectance.  A time period of copier non-use, exceeding a preset time period, or a copier on/off operation, referred to as critical events, results in a transient mode of copier operation which includes reduction of photoconductor charge magnitude during the next subsequent use, independent of the extent of the prior copier use history.  During such subsequent use, the toner-patch test cycle is operable to effect closed-loop control of changing the photoconductor's charge magnitude back to its nominal working value.  More specifically, so long as the results of a toner-patch test cycle indicate an acceptable toner density, the photoconductor charge magnitude is maintained at a lower than working level.  As the results of the toner-patch test cycle periodically indicate lower than acceptable toner density, as by a high light reflectance off the test patch, the photoconductor's charge magnitude is periodically increased until finally the working charge magnitude is reached.  The results of the toner patch test cycle are operable to add toner to the copier's developer only when the photoconductor's charge magnitude has been increased to at or near the working magnitude.
