Abstract: A paper tinting and drying machine has a tinting module and a dryer module spaced apart from one another by a predetermined distance so that aqueous liquid ink with less than five percent volatile organic compounds by volume applied to the underside of the paper can be visually inspected by the machine operator and so that ink application adjustments located on the paper output side of the tinter module can be accessed by the machine operator. Rollers in the tinting module constrain the paper to follow a path of travel through two sets of inking rollers so that both sides of the paper are evenly coated. After entering the dryer module without smearing or transferring wet ink to the dryer module input guide roller, the ink on the paper is dried by air knives and infrared heaters within the dryer module. In a first embodiment, the rollers in the tinting module drive the paper through the machine.

Abstract: A micro-computer is coupled to the X-Y coordinate drives of a plotting table or the like and it is programmed to provide for monitor displayed pattern design. Straight or circular lines are subdivided into a number of unit steps based upon the system resolution such that each unit step segment of a straight line and each unit step chord of a circular line corresponds to said system resolution. The sine and cosine functions of the slopes of said segments or chords are summed, and the X and Y coordinate drives are advanced one unit step each time the cosine and sine functions, respectively, crosses an integer boundary.

Abstract: A large scale X-Y plotting table is provided with electro-pneumatically controlled clamping bars at opposite ends, with roller-formed troughs adjacent thereto for supporting supply and take-up rolls of sail cloth or the like. The clamping bars are coupled to foot operated switches for locking the bars alternatively in the clamping or releasing position. Index marks plotted at the fabric edge and an index line on the table, as well as a longitudinal fence, facilitate indexing the fabric between adjacent plotting fields corresponding to window fields of the associated CAD equipment.

Abstract: The invention contemplates a document printer for the automatically indexed sequential account numbering of successive documents, with the added feature of printing alongside each sequential number an automatic indication of the validity or invalidity of the number printed, said indication being a "check digit" which, in conjunction with the printed account number, renders the printed account number self-checking. The invention is described in application to weighted-modulus self-checking systems of the Modulus 10 and Modulus 11 varieties, inter alia.

Abstract: The invention contemplates a non-rotary printing machine which accommodates continuously moving web along a single path of movement, for recycled precision imprinting of specially characterized information; the printing involves cooperative use of a printing-head unit on one side of the web and a printing-hammer unit on the other side of the web, and these units are indexibly positionable to enable the machine to print the characterized information in a selected one of at least two different alignment orientations with respect to the direction of web movement.
