摘要： A PAPER SEPARATOR FOR SEPARATING SHEETS OF PAPER FROM A STACK THEREOF. RUBBER ROLLERS ADVANCE THE TOP SHEET FROM THE STACK AGAINST A PAIR OF PROTUBERANCES OF SHALLOW HEIGHT. THE SHEET OF PAPER SNAPS OVER THE PROTUBERANCES. IF TWO SHEETS ARE INADVERTENTLY MOVED EDGEWISE FROM THE STACK, THE TOP SHEET SNAPS OVER THE PROTUBERANCES, BUT HOLDS THE LOWER SHEET DOWN AGAINST THE PROTUBERANCES WHICH PREVENT ADVANCE OF THE SECOND SHEET.

摘要： A step-wedge is reprinted four times, one for each of three colors plus black and white as a mask. The reprinting is in a different position each time, giving a total of four different positions with one selected value overprinted by each color to show the effect of the overprint, namely to demonstrate a neutral. If a neutral gray is obtained, then it is known that the printing is correct. If no neutral is obtained, a ready reference, not requiring the use of a densitometer or separation filters is immediately at hand.

摘要： A compact or tabletop electrostatic book copier having at the top thereof an exposure station on which a book is laid with a mirror and lens optical system for projecting an image of the book page to a more or less vertical exposing station. Paper is fed from a paper safe at the bottom of the machine through a charging unit substantially horizontally, and then substantially vertically up to the exposing station where the paper is exposed. From the top of the exposing station the paper is fed face down in a downwardly diagonal direction over a developing station, and along an inverting reentrant path to a delivery station immediately above the developing station where the copy is delivered face up.
