Providing plural precollated sets of copies by plurally recirculating a set of documents and normally making two consecutive identical copies per document per circulation, at one-half the copying rate of the copier, feeding these pairs of identical copy sheets separately into two of only 3 (or 4) movable compiler bins, sequentially accumulating and stacking these copy sheets into completed, compiled, collated copy sheet sets in each of the two compiler bins, and then removing the sets one at a time for finishing, from the opposite side of the bins, and sequentially changing, for subsequent circulations of the sets of documents, which 2 of the 3 compiler bins are being fed pairs of copy sheets, and which compiler bin is not, so that a compiled set of copy sheets may be removed from its bin or left in awaiting finishing of a prior set without having any copy sheets fed into that bin, in coordination with and without interfering with said feeding and directing of other copy sheets into other compiler bins. Preferably two copy sheets are fed into the same compiler bin in directly immediate sequence (the second copy of one document and the first copy of the next document) to reduce the number of operations of the bin gates. When there are an odd number of documents, preferably three identical copies are made of each document in a final copying circulation of the document set and fed into all 3 bins, unless the copies are duplex and there are too many documents for plural duplex buffer sets.

Copying system for on-line finishing

The present invention enhances the resolution and quality of characters of a system receiving the information initially in the form of video display pixels and providing hard copy output. This is accomplished by storing at least three successive lines of video data in successive, parallel connected shift registers, applying the outputs of the shift registers to a decoder, and generating driving signals for the printer head. The decoder compares the pixels on the same line as well as in preceeding and succeeding lines that surround each specific input pixel to generate the printer head driving signals according to whether straight or curved line segments are to be formed. In effect, the printer increases the density of the information elements and simultaneously provides rounding off of character edges and smoothing of diagonals.

An apparatus in which articles are stapled to one another. A staple is driven through the article so that a portion thereof protrudes therefrom. The staple legs protruding through the articles are bent into substantial contact therewith so as to clinch the staples. In the clinched position, the staple legs are closely adjacent to one another and may be overlapping. During the clinching operation, the staple legs are guided by a groove in the surface affecting bending. Initially, the stapled leg is received in the central region of the groove. The central region of the groove has a greater cross-sectional area than the end region thereof.

Staple clinching mechanism

An improved ocular plethysmograph for use in conjunction with known pulse volume recorders, and offering increased performance and simplicity as well as lower cost of manufacture. The device employs a means whereby a large DC pressure signal is cancelled across a very sensitive DC pressure transducer employed to detect directly the tiny pressure fluctuations resulting from minute volume plethysmic changes of the human ocular globe. The means employed provides secondary advantages in use.
