摘要： This invention relates to an improvement in an arrangement for ammonia feed in copying equipment with several switchable adsorption vessels, for instance four or five vessels, containing an adsorbent, at least one adsorption vessel of which in each case, the adsorbent of which is not saturated with ammonia, is charged with ammonia-containing air extracted from a developing chamber before this air leaves the copying equipment as cleaned exhaust air, and at least one adsorption vessel of which after saturation of the adsorbent can be regenerated by heating, and means whereby the liberated ammonia can be fed to the developing chamber.Each adsorption vessel can be connected via respective means to a line for the air extracted from pre-chambers of the developing chamber. The respective means are actuated according to a step-by-step switch unit. Furthermore, each adsorption vessel includes a gas outlet which can be either connected to the developing chamber or to an exhaust air line.The step-by-step switch unit receives a control signal from a measuring instrument which measures the concentration of the ammonia in the exhaust air. Measuring probes determine the concentration of ammonia, respectively of water vapor, in the developing chamber and are connected to a control instrument which serves to actuate the electrical heating of the adsorption vessels.

摘要： A conveyor belt for use in electrophotographic copying apparatus, which conveyor belt has a plurality of apertures therein and comprises electrically insulating material that can be electrostatically charged, the size and the distribution of the apertures being such that sheet material on which a copy is to be produced can adhere by electrostatic attraction to the belt when the belt is installed in the apparatus and such that the tendency of the belt to impair the copy is less than that for a belt without apertures.
