Patent number: 5671680Abstract: The invention is a guidance device for a railway vehicle and, more generally, is a guidance device for any track-following vehicle. The guidance device has a guide wheel which is complementary with a substantially circular guide rail, and which is capable of pivoting about the guide rail from rotation about a substantially horizontal axis to rotation about a non-horizontal axis. The guide wheel is pivoted by a pivoting member to which the guide wheel is mounted. The substantially circular guide rail extends parallel to the main rails of the track and is located at least in the area of a bend in the track, e.g., a branch in the track, a curve in the track, or the like. The guide rail is preferably positioned laterally outboard of one of the main rails of the track. The track may additionally comprise a second guide rail which is positioned laterally outboard of the other main rail of the track. In an alternate embodiment, the track may have a single guide rail positioned between the main rails of the track.Type: GrantFiled: June 3, 1996Date of Patent: September 30, 1997Inventor: Anthony Armand DelGreco

Patent number: 5520676Abstract: An absorbent article having a main body portion and a pair of flaps joined to the main body portion. The main body portion comprises an absorbent assembly and a pair of retaining members joined to the absorbent assembly to form recessed areas wherein the flaps may be tucked. Each retaining member comprises a unitary release material joined thereto such that the unitary release material superposes and is releasably secured to the flap adhesive when the flap is folded and tucked into the recessed area.Type: GrantFiled: July 17, 1995Date of Patent: May 28, 1996Assignee: The Procter & Gamble CompanyInventors: Bruce W. Lavash, Thomas W. Osborn, III, Stephen P. Kearney

Patent number: 5330461Abstract: An absorbent article having a main body portion and a pair of flaps joined to the main body portion. The flaps are folded over the garment side of the main body portion such that the flap adhesives and the central pad adhesives can be covered by a single release liner. The flaps may or may not be used while the absorbent article is being used, i.e., the absorbent article may be used by wrapping the flaps around the edges of the crotch region and securing the flap adhesives to the underside of a user's panty; alternatively, the flaps may be left in their folded configuration on the garment side of the main body portion and the flap adhesives may be secured, along with the central pad adhesive, to the inner crotch region of the panty.Type: GrantFiled: December 22, 1992Date of Patent: July 19, 1994Assignee: The Procter & Gamble CompanyInventor: Karen K. Leeker

Patent number: 5246433Abstract: A unitary disposable garment, such as disposable training pants, having a high degree of stretch in the cross-machine direction and fitting a broad range of wearer sizes. The unitary disposable garment is manufactured from a chassis and has a waist opening, two leg openings and a pair of side seams which join the front portion of the chassis to the rear portion of the chassis. The unitary disposable garment preferably has an absorbent assembly, i.e. an absorbent insert, secured to the inner layer of the chassis. The chassis from which the unitary disposable garment is manufactured, has four elasticized ear flaps; each ear flap is elasticized by securing an elastomeric element thereto and mechanically stretching the ear flap and the elastomeric element such that the ear flap is elastically extensible in the direction of initial stretching. The front portion of the chassis is then joined to the rear portion of the chassis on each side of the disposable garment by a seam.Type: GrantFiled: November 21, 1991Date of Patent: September 21, 1993Assignee: The Procter & Gamble CompanyInventors: Margaret H. Hasse, Russell P. Bridges, Steven W. Miller

Patent number: 5236430Abstract: A disposable garment manufactured from a fusion-slit chassis having a pair of seams. The seams are formed by folding the chassis in the crotch portion so that the longitudinal side regions of the front portion and rear portion are superposed to form seaming areas; each seaming area is treated with ultrasonic energy sufficient to sever the material of the seaming area in a first area while simultaneously bonding the material of the seaming area in a marginal area adjacent the first area to form a flangeless seam which extends from the disposable garment 1/16" or less, preferably 1/32" or less, and in a preferred embodiment will form a splice between the front portion and rear portion of the chassis. The seaming area will consist of layers of polymeric material and in a preferred embodiment will consist of nonwoven webs of 100% polypropylene fibers.Type: GrantFiled: November 21, 1991Date of Patent: August 17, 1993Assignee: The Procter & Gamble CompanyInventor: Russel P. Bridges

Patent number: 5230851Abstract: A process for making a refastenable mechanical fastening system, made of free formed prongs joined to a substrate. The prongs taper and are nonperpendicularly oriented relative to the plane of the substrate. Each prong has an engaging means projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate, stretching the liquid material in a direction parallel to the plane of the substrate and severing the stretched material to form the distal end and engaging means of the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent garment, specifically a diaper.Type: GrantFiled: March 7, 1991Date of Patent: July 27, 1993Assignee: The Procter & Gamble CompanyInventor: Dennis A. Thomas

Patent number: 5185052Abstract: Disclosed is an apparatus for longitudinally pleating a moving lamina. The apparatus features a curved axis roll having a stationary axis circumscribed by a rotating sleeve with a plurality of circumferentially oriented grooves in the rotating sleeve. The pleats are produced by the intermeshing of the lamina with the grooves of the rotating sleeve. Preferably a complementary curved axis roll having lands which interdigitate with the grooves of the first roll is used in conjunction with the first curved axis roll.The apparatus preferably further comprises a third curved axis roll disposed upstream of the first curved axis roll to substantially equalize the paths of travel of any points on the moving lamina by compensating for differences in the paths of travel between the edges and centerline of the lamina.Type: GrantFiled: June 6, 1990Date of Patent: February 9, 1993Assignee: The Procter & Gamble CompanyInventors: Charles W. Chappell, John J. Angstadt

Patent number: 5180534Abstract: The invention is a refastenable mechanical fastening system, made of free formed prongs joined to a substrate. The prongs taper and are nonperpendicularly oriented relative to the plane of the substrate. The prongs also have an azimuthal angle relative to the machine direction of the substrate. Each prong has an engaging means projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate, stretching the liquid material in a direction parallel to the plane of the substrate, severing the stretched material to form the distal end and engaging means of the prong, and imparting an azimuthal angle to the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbant garment, specifically a diaper.Type: GrantFiled: December 21, 1990Date of Patent: January 19, 1993Assignee: The Procter & Gamble CompanyInventors: Dennis A. Thomas, David J. K. Goulait, Robert G. Cox, Jr.
