Abstract: The continued performance of a charge corona for an electrostatic copy machine is enhanced by the provision of specially configured corona wire support blocks that minimize current leakage through hygroscopic salts accumulating on the support block surface. The support blocks are configured to include a surface interruption that provides a cul-de-sac including surface which is shielded from the path of corona current and ionized gas thereby preventing accumulation of salts on the shielded portion.

Abstract: A mechanism is disclosed for the automatic erasing of typing errors utilizing a fully serialized and automated correction apparatus where the correction is accomplished by a single backspace operation allowing both the erasure of the erroneously typed letter and the typing of the proper letter. The backspace operation repositions the typewriter carriage for the correction of the erroneous letter and at the same time inhibits the escapement of the carriage for a single print cycle allowing the corrected letter to be printed over the correction without requiring an additional backspace operation. The escapement mechanism is re-engaged during the correction cycle so that the carriage advances of the print cycle.

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 array of test probes individually mounted to a test fixture is provided for contacting a substantially increased number of pads on high density circuit chips. The probes are mounted in side by side relationship in groups with each group of probes making contact with respective pads that are proximately positioned and, preferably, on the same radial line of a chip. Each probe has a contact blade carried by parallel springs of minimum gram load to assure uniform force deflection contact ratios and each blade-spring arrangement acts as the electrical conducting circuit for that probe of the array.

Abstract: A continuously operating transfer reproduction apparatus includes a cyclic control unit which automatically effects alternate redevelopment and reimaging cycles when reproducing multiple copies of the same master. An electrophotographic plate travels in a closed loop past a moving optical system which images the plate with a light image of the master creating a latent electrostatic image on the plate. The latent image is developed at a developing station and transferred to a substrate at a transfer station as the plate travels therepast. Increased throughput speed is achieved by effecting a fixed number of redevelopment cycles while the moving optical system is resetting. Thus, the plate continues its travel past the resetting optical system to the developing station where the latent image is redeveloped and thence to the transfer station for transfer of the developed image to a second substrate. The plate is then cleaned and charged prior to being reimaged with the light image of the same master, and the process continues until the requisite number of copies have been reproduced. In one embodiment, multiple imaging areas, preferably an odd number thereof, are located on the plate facilitating rapid alternate imaging and redevelopment cycles.

Abstract: Documents are automatically recirculated for copying by a copier from a stack which is accessed top document downward. Documents are stacked faceup in an upper tray and moved as a group to a lower tray where they are stacked facedown, with the first document in the upper tray appearing in a facedown position at the bottom of the lower tray. The top document in the lower tray is then removed for copying and returned to the bottom of the upper tray, thus peserving the original document order for further copying. The copier normally scans stationary documents placed on a glass platen; for example, individual sheets of paper or book pages may be placed on the glass platen and held stationary while the optics causes light to scan the page. During automatic recirculation of stacks of the documents, however, the scanning optics is "parked" and documents removed from the lower tray are imaged while scanned past a fixed exposure area on the glass platen on the way back to the upper tray.
