Abstract: A document collating and inserting system having displays for document count verification. A plurality of bank checks belonging to a check set are fed, counted and stacked at a stacking station while simultaneously an associated statement is fed to an imaging station where a number imprinted thereon is imaged by a video camera and displayed on a video monitor. The number represents a predetermined number which should equal the actual number of checks counted, the actual count also being displayed. An operator makes a visual comparison of the two displayed numbers and, if they are in agreement, initiates a cycle of the system thereby forming a collation of the statement and checks and transporting them to a holding station. From the holding station the collation is inserted within an envelope provided by an envelope feeder during the next cycle of the system. If the two numbers are not in agreement a mismatch switch is provided for the operator to activate before cycling the system.

The other non-volatile memory stores cumulative data upon power-down.

Abstract: An improved drop-on-demand ink jet print head is formed of a plurality of superposed metal plates that are diffusion bonded into a unit. A plurality of superposed metal plates are diffusion bonded into a unit. Punched and/or etched holes form ink passages that include manifolds that supply ink chambers through restrictors and exit orifices that supply ink to nozzles for ejection as droplets. Crosstalk among nozzles is minimized by the use of a compliant manifold plate and a relief slot in an adjacent nozzle plate so as to be coextensive with its associated manifold. The restrictors and the nozzles are substantially equal in diameter and length. The print head produces droplets up to 80 micrometers in diameter at frequencies up to 7 KHz with little variation in droplet size and velocity as a function of frequency.

Abstract: This invention relates to apparatus for electronically recording using a xerographic machine and, more particularly, to an assembly of monoliths containing light emitting diodes (LED's) that yields a relatively long array of LED's with high light density and a contiguous set of light centers. A fiber optic cover is placed over the exposed surfaces of the LED's to counter the effects of the divergent angle of light emitting from the LED's and to protect the LED's from damage. A gel having a relatively high refractive index is applied between the LED's and the fiber optic cover to further counter the effects of the divergent angle of light.

Abstract: A mailer for the delivery of replacement units and the return of replaced units. Preferably the units include electronic components such as PROM's mounted on printed circuit boards. A replacement unit is held within the mailer by a restraint in a position such that an address for a customer to whom the replacement unit is to be delivered affixed to the replacement unit is visible through a window in the mailer. Insertion of a replaced unit into the mailer causes the restraint to release the replacement unit and secure the replaced unit in such a position that no address is visible through the window. Accordingly, the mailer would be returned to the vendor whose address is imprinted on the mailer with no need for further effort on the part of the customer.

Abstract: In accordance with the invention, a novel high-speed flap-opening apparatus is used in combination with a relatively large transfer roller having two spaced rollers disposed along the periphery to form two separated nips. The pivotable envelope flap-opener comprises guide means having a lip for engaging the flap of the envelope. The flap-opener is disposed at a first position for receiving an envelope from the first nip. The force of the envelope causes the flap-opener to move to a second position which guides the envelope to the second nip of the envelope. As the flap emerges from the first nip, the lip of the flap-opener engages the flap to bend it back as the envelope passes through the second nip.
