Patent number: 5207416Abstract: An apparatus in which a stack of sheets is detected at a preselected location. An air jet is directed towards an edge of the stack of sheets at a preselected location. A pressure transducer is located at the prescribed location and positioned to have the air jet at impact thereon. The pressure transducer is enabled to transmit a signal indicative of the absence of the stack of sheets at the preselected location in response to the air jet impacting thereon. The pressure transducer is inhibited from transmitting the signal in response to the stack of sheets blocking the air jet. When the stack of sheets blocks the air jet, the signal from the pressure transducer indicates the presence of the stack of sheets at the preselected location. A pneumatic stack height detector of this type may be used to regulate the movement of a stack of sheets used in electrophotographic printing machines.Type: GrantFiled: March 27, 1992Date of Patent: May 4, 1993Assignee: Xerox CorporationInventor: Jose J. Soler

Patent number: 5205587Abstract: A modular frame for automotive vehicles, which comprises a pair of side rails oriented parallel to one another, each side rail having a plurality of apertures being substantially similar in size and shape with respect to one another. Cross members and auxiliary mounts are secured to the side rails by adapters that have a size and shape corresponding to the apertures in the side rails. The means for securing the adapters to the side rails allows the load to be distributed over a wide area of the side rail to reduce stress concentrations. The combination of the adapters and the plurality of similar sized apertures results in a modular structural frame connection system for vehicles.Type: GrantFiled: April 19, 1991Date of Patent: April 27, 1993Assignee: Paccar Inc.Inventor: Larry W. Orr

Patent number: 5201508Abstract: An apparatus feeds and separates sheets individually from a stack of sheets. A nudger is disposed adjacent to at least a portion of the stack, and a mechanism, including a rotatable friction feed belt thereon, is disposed adjacent a sheet on the stack to be fed. A variable normal force is provided between the nudger and the friction feed belt of the mechanism. A sensor detects a lead edge of a sheet at a preselected location relative to the mechanism, and the increase in the normal force between the mechanism and the nudger is stopped when the lead edge of a sheet is detected by the sensor.Type: GrantFiled: August 14, 1992Date of Patent: April 13, 1993Assignee: Xerox CorporationInventor: Youti Kuo

Patent number: 5201504Abstract: An on-edge stacker for stacking envelopes comprises a transporter and diverter, an accumulator, a spider wheel for delivering diverted envelopes to a conveyor belt of the accumulator, and a propelling arrangement to a drive diverted envelopes to the spider wheel. The diverter includes a gate for intercepting and diverting envelopes from the transporter. The stacker includes a device for laterally offsetting envelopes. In one embodiment, the spider wheel is suspended in a free-floating manner against a spring load. The floating spider wheel displacement as a consequence of stack increase is sensed to energize the accumulator conveyor belt drive to reduce the displacement. The actuation of the envelope propelling arrangement is sychronized in correlation with the positions of spaces between legs of the spider wheel. In operation, a diverted envelope is aligned, selectively offset, and propelled into the spider wheel.Type: GrantFiled: May 28, 1991Date of Patent: April 13, 1993Assignee: Bell & Howell CompanyInventors: George Fallos, Harry C. Noll, Jr., David P. Nyffenegger

Patent number: 5201424Abstract: An apparatus for testing the stiffness of a sheet, such as a currency note, includes first cooperating rollers (36, 38) and second cooperating rollers (28, 32) arranged to urge the sheet along a feed path (48) The first rollers (36, 38) engage frictionally with the sheet and are caused to rotate with a greater peripheral speed than the second rollers (28, 32). As a result, there is a tendency for the first rollers (36, 38) to cause that portion of the sheet between the first and second rollers (36, 38; 28, 32) to buckle, this tendency being resisted if the sheet has a required degree of stiffness. First and second sensors (66, 68) are disposed on opposite sides of said feed path (48) for sensing a deflection of said portion of said sheet away from the feed path (48) by at least a predetermined amount, brought about by buckling of the sheet due to the sheet being insufficiently stiff.Type: GrantFiled: October 30, 1991Date of Patent: April 13, 1993Assignee: NCR CorporationInventor: David A. Hain

Patent number: 5193801Abstract: A moving bin sheet sorter has rotatable cams which engage portions of the sorter trays to move the trays at the ends adjacent to a sheet entry location between positions at which those tray ends are closely spaced above and below the sheet entry location and further spaced apart at the sheet entry location for receiving sheets supplied from a copier or printer. The cams are driven by an electric motor which is controlled to operate at a low speed as the trays are initially engaged and disengaged from the cam and a high speed during the major movement of the trays, thereby reducing noise resulting from high speed impact and shock loading of the cams and cooperative portions of the trays, as well as reducing noise resulting from high speed impact of said cooperative portions of the trays in guides for the trays.Type: GrantFiled: October 18, 1991Date of Patent: March 16, 1993Assignee: Gradco (Japan) Ltd.Inventors: Peter M. Coombs, Richard S. Howell, Jr.

Patent number: 5186449Abstract: The present invention is directed to the provision of a sheet feeder unit mounted in a copying machine or the like having a sheet transport mechanism. The sheet feeder unit feeds sheets to the sheet transport mechanism, and the sheets fed into the sheet transport mechanism are transported by the sheet transport mechanism. Each sheet being transported by the sheet transport mechanism is detected by a pair of sensors disposed with a prescribed space provided between each other, and the sheet transporting speed is calculated from the time in which the sheet travels the distance between the two sensors. The sheet feeding condition is set on the basis of the sheet transporting speed of the sheet feeder unit so that the sheets fed from the sheet feeder unit do not overlap each other.Type: GrantFiled: January 13, 1992Date of Patent: February 16, 1993Assignee: Mita Industrial Co., Ltd.Inventors: Ikuhiro Ohmi, Yoshiaki Yanagida, Soichi Matsuyama, Yoshihisa Ikuta
