Patent DE-19747766-A1 (DE)
Inventor: BECKER MARKUS
IPC: B65G1/137
Filed: 1997-10-29
Abstract: The invention relates to a method and a system for verifying the correct delivery by delivery units in lockable storage units, each of which takes up at least one delivery unit and is are provided with an identification label that can be accessed externally. The task-related identification label applied on the delivery unit is inputted and stored in the mobile read and evaluation device. Subsequently, the mobile read and evaluation device compares the scanned combination consisting of a first identification label and the task-related identification label with the combination previously stored in the mobile read and evaluation device consisting of a first identification label and a task-related identification, whereupon said device displays a result. After setting the delivery unit and locking the locking device of the storage unit, the task-related identification label that can be accessed externally and a second machine-readable identification label which can be accessed externally after locking through a window in the storage unit are successively detected by the mobile read and evaluation device in a predetermined interval.
Patent DE-19755965-A1 (DE)
Title: Return of off=centre conveyor belt to central position
Inventor: KOUZUKI RIKUZOU
IPC: B65G23/44
Filed: 1997-12-16
Abstract: A conveyor belt slip correction unit returns an off-centre conveyor belt (5) to its correct central position. The correction unit incorporates a slip-correction roller over which the belt passes, and slip recognition ring which is fitted to one end of the slip-correction roller, and which rotates independently of the slip-correction roller. When the belt moves off-centre, it exerts torque upon the slip recognition ring causing movement on the slip correction roller shaft end and exerting a counter movement on the belt. The functional components in the slip correction mechanism are incorporated within a single unit.

Title: Wäschebehandlungsmaschine mit bedienerfreundlicher Türöffnungstaste
Inventor: WILSDORF GERD
IPC: D06F39/14
Filed: 1998-07-31
Abstract: Zum Entriegeln einer Tür 2 einer frontal beschickbaren Wäschebehandlungsmaschine 1 muß eine Türöffnungstaste 3 betätigt werden. Diese ist in unmittelbarer Nähe zur Tür 2 angeordnet. Auf diese Weise kann die Tür sehr einfach geöffnet werden, da nach Betätigen der Türöffnungstaste 3 zum Entriegeln nur eine sehr kleine Bewegung zur Tür 2 hin nötig ist, um diese zu öffnen. Durch die erfindungsgemäße Anordnung der Türöffnungstaste 3 und der daraus folgenden optischen Zuordnung zur Tür 2 ergibt sich ferner in sinnfälliger Weise auch die Funktion der Türöffnungstaste 3, ohne daß diese notwendigerweise beschriftet oder mit einem Symbol versehen werden muß. Dies erleichtert darüber hinaus ihr Auffinden. Dadurch wird die heutzutage in den Vordergrund gerückte Bedienfreundlichkeit und Ergonomie der erfindungsgemäßen Wäschebehandlungsmaschine 1 wesentlich erhöht.
Patent DE-19842698-A1 (DE)
Inventor: MUEHLSCHLEGEL JOACHIM
IPC: H02P8/22
Filed: 1998-09-17
Abstract: The invention relates to a nominal current generating device designed to be used especially in a step motor control device. Said nominal current generating device comprises a table (2) from which the support points of an approximation function, e.g. a sinusoidal function, are read by a ring counter (11). Two intermediate values between two support points are generated by interpolation. Said interpolation is effected with the aid of a state modulator (10) that reads two support point values with two pulse duty factors during a clock pulse. The values are converted into an analog signal by a D/A converter (4), wherein a mean value and the interpolated intermediate value are generated by low pass filtering (5). Storage area can thus be saved by interpolation and the embodiment of the circuit can be simplified.

The die parts (11, 20) can be positioned in relation to each other using positioning means in such a way that they limit a forming cavity (30) and wherein at least one metal sheet element (40) is clamped between the die parts (11, 20) by means of sealing surfaces (17, 26, 27) and is formed hydrostatically in the forming cavity (30). The second die part (20) is disposed around the core element (11) in such a way that the positioned core element (11) is surrounded in certain areas by the second die part (20). When the formed sheet metal element (40) has undercuts, the second die part (20) consists of two (21, 22) or more parts for easy removal of the sheet metal element (40).
