Title: Transverse flux machine
Inventor: HILL WOLFGANG
IPC: H02K1/02
Filed: 1995-12-16
Granted: 2000-04-11
Abstract: In known transverse flux machines, the losses in the soft magnetic body prevent an increase in efficiency.  While the production of the winding is remarkable owing to its simplicity, the production of the laminated iron body conveying the magnetic flux incurs high costs.  In addition to the saturation in the iron, the use of air gaps restricts any increase in power density.  In accordance with the invention, the two air gaps (21) are arranged radially externally of the winding (15) and the magnetically hard and/or soft magnetic rotor parts (19, 20) which periodically close the magnetic circuit are arranged axially within the ends of the soft magnetic stator body (18).  This air gap arrangement gives rise to an air gap surface which is large relative to the external dimensions and the mass of the machine, and also relieves the load on the housing.  Owing to the segmentation of this u-shaped stator body, material waste during production is minimized and grain-oriented metal sheets can be used which, owing to their favorable properties, enable the efficiency and power density to be increased.  Segments of identical construction can be used in machines having different dimensions and power data. The type of construction according to the invention simultaneously reduces costs, weight, and losses in transverse flux machines.

Abstract: The invention is a method for producing a finished mail piece. The method allows a system user to select at a first node, a plurality of characteristics which define a mailing. These characteristics include selection of a document to be printed at a terminal node and a list of addresses to which the printed document will be sent. Once selections have been made, the print job is transmitted to a terminal node which comprises a data processor, an envelope printer, and a document printer among other elements. The document printer will print the document in accordance with the characteristics selected at the first node; and, the envelope printer will print addresses from the address list to corresponding envelopes. Once the document has been printed, it is inserted into the envelope by inserting means to form an unfinished mail piece. The unfinished mail piece is sealed and then franked with appropriate postage in order to form a finished mail piece. The mail piece is then placed into a mail stream for delivery to the destination address. A receipt indicative of the print job and delivery into the mail stream may be optionally generated by the terminal node and transmitted to the first node. Several nodal layers can be created such that the first node can transmit the print job to a second node which can further transfer the print job to subsequent nodes for printing and routing.
