Patent number: 6553837Abstract: The invention relates to a process for analysis of roller bearings (15) which have been installed in machines, by means of a sensor (10) a signal being recorded which is produced by the rolling motion, and the signal amplitude is evaluated in order to determine the presence and optionally the depth of the damage in the roller bearing running surface (56). In doing so a dynamic model of the roller bearing in the machine is considered, in which at least the bilateral contact stiffnesses (4, 6) of the rolling elements are considered in order to determine the transfer function between the force caused by the damage and the corresponding sensor signal which is then taken into account in the signal amplitude evaluation. The invention furthermore relates to a corresponding analysis device.Type: GrantFiled: August 14, 2000Date of Patent: April 29, 2003Assignee: Pruftechnik Dieter Busch AGInventor: Heinrich Lysen

Patent number: 6553838Abstract: The present invention relates to a method and apparatus for detecting anomalies, defects or electromagnetic properties of electrically conductive and magnetically permeable materials by using a magnet to partially saturate the material, thereby lowering its permeability, and sending a second, higher frequency oscillating electromagnetic wave into the material. The oscillating magnetic flux field permeating into the electrically conductive material induces eddy waves. As the apparatus passes over the material, the properties of the induced eddy currents, and the corresponding magnetic flux field induced by such eddy currents, changes as the properties of the material change. These changes can be the result of defects or anomalies in the material or in connecting welds.Type: GrantFiled: August 27, 2001Date of Patent: April 29, 2003Assignee: Em-Tech LLCInventor: Bijan K.

Patent number: 6553879Abstract: Apparatus for dispensing paper toweling includes a rotatable toweling support roller and a cutter blade pivotally mounted on the outer peripheral portion of the roller. The blade is movable between a first position in which the cutting edge of the blade is positioned closely adjacent to the outer peripheral portion and a second position in which the blade is disposed at an angle relative to the outer peripheral portion with the cutting edge of the blade spaced from the toweling support roller. The cutter blade when in the second position projects in a direction generally opposed to the direction of rotation of the toweling support roller so that pulling force exerted on the toweling by a user will bear against the cutting edge of the cutter blade to sever the toweling.Type: GrantFiled: September 13, 2001Date of Patent: April 29, 2003Assignee: Perrin Manufacturing CompanyInventor: Michel Morand

Patent number: 6553881Abstract: The configuration enables the introduction of a material web, which can be divided up into material sub-web strands, into the conveying paths of an angle-bar superstructure of a rotary printing machine. A slitting arrangement, which can be positioned in a variable manner in the angle-bar superstructure, and web drawing-in devices and components for attaching the material web or the material sub-web strands to the web drawing-in devices are provided. Assigned to the web-running plane is an adjustable advancement element which bridges a contact-pressure gap in relation to a mating roller, accommodated in the angle-bar superstructure, and by way of which one of the material sub-web strands or can be attached to an introduction element which can be moved into the web-running plane.Type: GrantFiled: July 13, 2001Date of Patent: April 29, 2003Assignee: Heidelberger Druckmaschinen AGInventor: Jean-Claude Marmin

Patent number: 6553882Abstract: A housing having an integral receptacle which is particularly useful for pencil sharpeners. The receptacle is attached to the body so as to be pivotable between a closed position, for closing a cavity of the housing, and an open position, for exposing the cavity. This is useful, for example, for emptying pencil shavings in a pencil sharpener. Attachment of the receptacle to the housing minimizes accidental opening of the receptacle and spillage of shavings. In the open position, the receptacle also serves as a spout for controlled disposal of shavings. In the preferred embodiment, the housing and receptacle have a mating rib and groove on opposing sides of the cavity which interfit when the receptacle is in the closed position to form a seal trap shavings within the cavity. Additionally, the receptacle is provided with a lower surface and rearward edge positioned to form a seal with the housing when the cover is in the closed and open positions, respectively.Type: GrantFiled: April 5, 2000Date of Patent: April 29, 2003Assignee: Hunt Holdings, Inc.Inventors: Phillip Bruce Daley, Jr., Peter Bressler, Peter Byar, John Coleman, Leslie Juhng, Mathieu Turpault

Patent number: 6553883Abstract: The apparatus for cutting a weblike material (N) fed continuously along a path (P) through said apparatus comprises a rotating cutting cylinder (101) and an opposing member (105), these being arranged on opposite sides of said path (P). On the cutting cylinder are a plurality of blade segments (111) distributed along the length of the cutting cylinder and connected to actuators (119, 121) for producing a movement of selective extension and retraction of the blade segments (111) with respect to the cutting cylinder (101).Type: GrantFiled: November 3, 1999Date of Patent: April 29, 2003Assignee: Fosber, S.p.A.Inventor: Mauro Adami

Patent number: 6553884Abstract: An adhesive tape dispenser for dispensing and cutting a length of an adhesive tape. The adhesive tape dispenser comprises an adhesive tape cutting device. The adhesive tape cutting device comprises a) a resting surface to which a tacky side of said adhesive tape can be adhered while the adhesive tape is being cut, b) two lateral webs extending in the same direction from both edges of the resting surface to serve as guides for the adhesive tape, and c) a cutting blade having a blade edge and positioned on an inner side of one or both lateral webs in such a way that the blade edge is inclined at an angle which is oblique relative to the resting surface. The lateral webs have a height from the resting surface which is the same or is higher than each cutting blade. The adhesive tape dispenser is useful to dispense and cut adhesive tapes comprising a backing of biaxially oriented or highly stretched film, such as polyolefin.Type: GrantFiled: September 16, 1998Date of Patent: April 29, 2003Assignee: tesa AGInventors: Bernd Lühmann, Ralf Schliephacke, Jörn Leiber, Andreas Reklau, Hans Hazes, Hansjürgen Linde, Uwe Neumann, Peter Kubasch

Patent number: 6553885Abstract: A knife blade for cutting food products includes a cutting edge having a concave circular curved central portion and opposed linear end portions tangentially intersecting and extending away from opposite sides of the circular curved central portion. The shape of the cutting edge results in enhanced stability of the knife blade when slicing food products driven into the cutting edge and across the blade width.Type: GrantFiled: May 2, 2001Date of Patent: April 29, 2003Assignee: Urschel Laboratories, Inc.Inventors: Eugene H. Cole, Charles E. Rowell

Patent number: 6553886Abstract: A hide splitting machine according to the invention has two pivot arms, mounted on modified journals at each end of a rubber roller, that are connected to two ring roller swivel arms attached to each end of the ring roller. The ring roller swivel arms connected to the pivot arms allow constant radial distance movement of the ring roller along the circumference of the rubber roller. Therefore, the ring roller can be retracted or moved away automatically, without possibility of mechanical damage, from the razor sharp band knife and ring jaw insert edge. The automatic retraction of the ring roller a preset distance allows splitting machine operators to easily access the ring jaw insert for safe, quick and efficient manual cleaning of the ring jaw insert edge. The automatic retraction of the ring roller further eliminates physical handling and/or manual removal of the ring roller from the splitting machine during the ring jaw insert edge cleaning process.Type: GrantFiled: December 12, 2000Date of Patent: April 29, 2003Inventor: Vitomir Mance
