Patent number: 9111086Abstract: In an external system, a request handler may receive, at the external system, a logon ticket from a proprietary software system, the logon ticket associated with a request from a user of the proprietary system for access to the external system. A ticket handler may provide the logon ticket to an authentication service which is configured to perform a validation of the logon ticket at the proprietary system. A session manager may receive, from the authentication service and based on the validation, a user session and access rights related to the requested access. An access control manager may provide the requested access to the user via the proprietary system, according to the access rights and within the user session.Type: GrantFiled: April 18, 2011Date of Patent: August 18, 2015Assignee: SAP SEInventors: Ajit Dash, Ning Li, Wolfgang Janzen, Thomas Rinneberg

Patent number: 6779652Abstract: A chain link (10) of a curved conveyor chain has been proposed, which has a carrying device (12) for transport material. A head part (24) disposed under the carrying device (12) has a lateral bore (40) for a pin (48) of a first adjacent chain link (10). The head part (24) is adjoined by a fork-shaped section (26) with two legs (44), which encompass the head part (24) of a second adjacent chain link (10). The legs (44) and contain lateral bores (46). A pin (48) is also provided, which is contained in the lateral bores (46) of the legs (44) and in the head part (24) of the second adjacent chain link (10). Projections (52) protrude from the legs (44) and are designed to be guided in a guide profile and driven by means of a driving wheel. The object of the invention is to produce a chain link (10), which permits a favorable introduction of force.Type: GrantFiled: June 12, 2003Date of Patent: August 24, 2004Assignees: Robert Bosch GmbH, Flexon Systemplast GmbHInventors: Wolfram Baier, Guido Hettwer, Peter Rothfuss, Olaf Klemd, Wolfgang Janzen, Klaus Nendel, Peter Meynerts

Patent number: 4953691Abstract: A roller chain conveyor including detachable, snap-on, top-plate assemblies having spaced apart, guide plate members adaptable to overlap the outer ends of connecting pins, so as to avoid contact thereof with laterally disposed guide tracks, especially during operation of the conveyor along curvilinear paths of travel in which transverse forces act on the roller chain. The absorption of the transverse forces occurs over guide plates that overlap the roller chain conveyor. The assemblies include a plurality of resilient, spring-like tongue members disposed about each guide plate member, the tongue members having recesses formed therein to receive in holding engagement a portion of the circumferential surface of each of the connecting pins. This arrangement, whereby there is provided a distinct, rigid, separate guide plate member and a resiient spring-like tongue member, provides a simple device for attachment and removal of the snap-on top plate assemblies to and from the roller chain.Type: GrantFiled: July 22, 1988Date of Patent: September 4, 1990Assignee: Flexon Holland, B.V.Inventor: Wolfgang Janzen

Patent number: 4283183Abstract: In a chain wheel system tooth blocks are mounted on the circumferential periphery of the drum and are driven by a mating chain. The length of the tooth blocks equals at least the spacing between two links in the mating chain. The tooth blocks are attached to spacers fitted to the circumferential periphery of the drum. Various segment pieces or spacer members can be attached to the drum separating adjacent tooth blocks.Type: GrantFiled: April 25, 1979Date of Patent: August 11, 1981Assignee: Amsted-Siemag Kette GmbHInventors: Wolfgang Janzen, Ludger Frenker-Hackfort

Patent number: 3940122Abstract: In a quick acting clamping device a pair of pressure levers are mounted in a cylindrical housing for displacement between an unclamped position and a clamped position. In the unclamped position the pressure levers extend obliquely to the cylindrical axis of the housing and in the clamped position they extend parallel to the cylindrical axis. Movement of the pressure levers between the clamped and unclamped positions is provided by mounting one end of each of the levers in a pressure piece. The pressure piece is located in a bore in a piston mounted in another bore within the cylindrical housing. The bore in which the piston is mounted extends transversely of the housing, while the bore in the piston extends in the direction of the cylindrical axis of the housing. The housing includes passageways for introducing pressurized hydraulic fluid into the opposite ends of the bore containing the piston.Type: GrantFiled: April 16, 1974Date of Patent: February 24, 1976Assignee: Amsted-Siemagkette GmbHInventor: Wolfgang Janzen
