Publication number: 20100066008Abstract: Apparatus and method for controlling the slope angle of sheet stock in a feeder/loader for copying/printing where leading edge side of the stock is elevated by elevating one side of the support tray to position the top sheet for nudging into a nip. When the slope angle of the stock reaches a critical value, in one version, a separate elevating mechanism raises the opposite side of the support tray to prevent the slope angle from exceeding the critical value. In another version, the elevating mechanism for the opposite edge is connected to the elevating mechanism for the leading edge of the stack and raises the opposite edge when the sheet stock slope angle reaches a threshold value to prevent potential misfeed.Type: ApplicationFiled: September 18, 2008Publication date: March 18, 2010Applicant: XEROX CORPORATIONInventors: Linn C.

Patent number: 6258400Abstract: A process and apparatus for holding a plurality of medicaments to be coated is disclosed. A support member is provided having a receiving surface with a plurality of channels to communicate a vacuum across the receiving surface and an aperture operable to couple the plurality of channels to a vacuum source. A flexible mat having a perimeter shaped to engage the support member in a sealed relation is provided on the support member. The flexible mat includes a plurality of medicament receptacles mounted to a first surface and adapted to receive the medicaments. The medicament receptacles initially are in a first position when no vacuum is applied. In the first position, the medicament receptacles are positioned to receive a medicament. When a vacuum is applied, the medicament receptacles change to a second position in which the medicament receptacles are positioned to hold the medicament and permit coating thereof.Type: GrantFiled: March 23, 1999Date of Patent: July 10, 2001Assignee: Bayer CorporationInventors: Jeffrey D.

Patent number: 6213324Abstract: A frangible closure has a closure sheet having a central weakness formed substantially though a medial portion. The central weakness has a thickness and a central portion of greater thickness than the thickness of the central weakness so as to resist shearing of the central weakness. A lateral skirt surrounding the closure has at least a partial radial weakness therebetween for cooperating with the central weakness and enabling the central weakness to fracture.Type: GrantFiled: November 17, 1999Date of Patent: April 10, 2001Assignee: Eastman Kodak CompanyInventors: Scott H.

Patent number: 6196281Abstract: A fluid transfer system suitable for emptying a container or flask closed by a liquid-tight removable frangible closure obtained from a material that can be recycled. Photoprocessing materials are transferred from a first container having the frangible container into an adjoining second container. The frangible closure has a single closure sheet fixed to a lateral skirt for mounting the frangible closure on the spout of the flask, for example with a screw. The flask is emptied by tipping the flask onto a perforation device that perforates a central weakness in the closure sheet which connects with a radial weakness at the seam of the closure sheet and lateral skirt, allowing for lower puncture forces.Type: GrantFiled: November 17, 1999Date of Patent: March 6, 2001Assignee: Eastman Kodak CompanyInventors: Scott H.

Patent number: 6195911Abstract: A process and apparatus for the gelatin coating of medicaments which includes a continuous conveyer system to advance a plurality of pallets through a loading station, at least one dipping station, at least one dryer station, a reorientation station and an unloading station. Medicaments to be coated are loaded into pallets at the loading station and advanced to the first dipping station where a vacuum is applied to secure the medicament to the pallet. The pallet is inverted and a first portion of each of the medicaments is dipped into a coating mixture. The pallet is then returned to its upright position, the vacuum is removed and the coating is dried. The medicaments are then transferred from the first pallet to a second pallet by a reorientation mechanism. The second pallet is then advanced to a second dipping station which operates in the same manner as the first dipping station.Type: GrantFiled: March 23, 1999Date of Patent: March 6, 2001Assignee: Bayer CorporationInventors: Jeffrey D.
