Abstract:
A flat cable for distributing electrical power between hingeable or demountable pieces of electrical apparatus is made up of thin, flat conductors nonrigidly mounted one on top of the other. The nonrigid mounting of the conductors relative to each other permits one to slip or slide relative to the other and thereby improve flexure of the cable and also increase the number of flexures the cable can be cycled through before it fails. Nonrigid mounting can be achieved by several different configurations. First, each flat conductor can be provided with its separate insulating layer and then the two insulated conductors may be held one over the other loosely so that they may slide or slip relative to each other. Second, a flat insulating cable may have a partition across its width so that one flat conductor may be placed in one partitioned section and the other flat conductor may be placed under the other conductor in the second partitioned section. Third, separately insulated conductors may be taped together at spaced locations so as to allow each conductor to slide within its own insulation and to allow relative movement of the conductors between the spaced locations.
Abstract:
An elastic diaphragm switch has a diaphragm assembly formed as an airtight interface between a substantially rigid substrate material and a diaphragm of highly flexible film to which is adhered a copper conductive pattern designed to withstand large deflections without fatigue. This is accomplished by an extended length conductor such as a spiral conductor path extending from the diaphragm supported contact to a stationary conductor. Thus the diaphragm switch may be formed of a single thin film and activated by very low-pressure levels.
Abstract:
Print heads mounted on a carriage moveable parallel to the platen are automatically retracted away from the platen when the carriage reaches a home position to facilitate paper insertion and thereafter automatically move to the printing position as the carriage leaves the home position under a start command.
Abstract:
Documents are inserted into a bin beneath a decant stack already in the bin. An air bearing holds the document stack above the floor of the bin. A lifting mechanism lifts the stack along one edge so that a document is driven driven the last sheet in the stack and the floor of the bin. A selectively activated drive means positioned on the floor of the bin advances the document into proper registration into the bin. Documents can be fed from the top of the stack simultaneously with the bottom stacking operation.
Abstract:
A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex copy mode, wherein sheets are fed from a selected sheet stack one at a time, to the copier's transfer station, by a sheet feeding means which includes a combing wheel. The combing wheel shingles the leading edge of the stack's top sheet to an open feed roller nip, to be sensed there by a pneumatic sensor. Sensing of this leading edge causes the combing wheel to be lifted off the stack. Subsequently, at a time determined by the crpier's control logic, the drive nip closes to thereby feed the top sheet to the copier's paper registration gate, and then to its transfer station. As soon as this sheet's trailing edge has cleared the pneumatic sensor, and the drive nip has opened, the next sheet is staged at the shingled position, in the open drive nip. Side-one copied sheets, of intended duplex copies, are automatically stacked in a duplex bin. The bottom of the duplex bin includes a flat, resilient bottom-of-the-bin pad. This pad's position is adjustable in a plane parallel to the bottom of the duplex bin, to facilitate control of the direction in which sideone copied sheets are fed out to the copier's paper registration gate, for side-two copying.

A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex copy mode, wherein sheets are fed from a selected sheet stack, one at a time, to the copier's transfer station, by a sheet feeding means which includes a coming wheel. The combing wheel shingles the leading edge of the stack's top sheet to an open feed roller nip, to be sensed thereat by a pneumatic sensor.

Abstract:
A sheet registration apparatus for positioning sheets in a registered position on a work surface such as the document platen of a convenience copier/ duplicator machine. The apparatus includes a bidirectional servo-controlled sheet transport for conveying the sheet over the work surface. A sheet sensing device is disposed within the path of sheet travel A controller monitors the sensing device and activates a position control routine following the occurrence of a predetermined level change in the signal generated by the sensing device. At the end of the position control routine, the transport is stopped thereby positioning the sheet in the registration zone. The apparatus enables sheet registration for a machine operating in a duplex and/or simplex mode. The apparatus further enables registration at any point on the document platen.
