Abstract: The optical illumination and scanning system for document reproduction consists of two rotatable mirrors mounted in fixed side-by-side relationship. A light source illuminates the first mirror which reflects the light to a section of an original document. This light is reflected by the document to the second mirror which reflects this return beam through a lens system to a photoconductor surface. The mirror assembly oscillates across the entire original without changing the fixed relationship between the light beam reflected to the original and the return beam focused on the photoconductive surface.

Abstract: An ink jet printing apparatus is described having facilities for printing information in character locations, (boxes) each character location comprising a plurality of vertical columns of drop locations, and a number of characters comprising a line of information. Structures and circuits are included for insuring correct location of information within the character boxes and also providing for one mode in which characters are printed continuously line-by-line and another mode in which characters are printed incrementally character-by-character. During incremental printing, as well as the first character in a line or group of characters, provision is made for re-bounding the printhead back into the box of the character just printed, that is, prior to the next character box to be printed to insure that when the printhead starts up again for the next character that all drop components for that character, including any located in the immediate vicinity of the character boundary, are properly placed during printing.

Abstract: Information items are selected by permutative positioning of a group of adjacent two-position slide members. The slide members are characterized by their compact arrangement of blocking and passing code portions which cooperate with both of two adjacent information transmission channels. The compactness of the system, achieved by the code portion arrangement, is accompanied by some loss in code set efficiency as to the number of outputs selectable from a permutation of a given order; however, certain unique and repetitive patterns exist by which reasonable efficiency can be achieved.

Abstract: A clamp (11) for holding a flexible sheet (12) on a rotary carrier (10) tightens the grip on, and pulls, the sheet upon rotation of the carrier, as a result of centrifugal forces generated on two weights (28, 29) attached to two cooperating arms (21, 22) within the clamp. The magnitude of the grip-tightening force is dependent upon the mass of a grip-tightening weight (28) attached to the clamp. The magnitude of the sheet-pulling force is dependent upon the mass of a sheet-pulling weight (29) attached to the clamp. The clamp faces (18, 19) are mounted (23) for concurrent movement along the periphery of the carrier to prevent tearing or other damage to the sheet when it is pulled as the carrier is rotated.
