Abstract: The manufacturing effort for producing electrical machines with pole teeth which are fitted with permanent magnets is intended to be simplified. The permanent magnets are inserted into the pole teeth only at the end of the manufacturing process, for this purpose, with the pole teeth each comprising two pole teeth halves (1, 2). An insertion device (3) which may be in the form of a frame is arranged between the pole teeth halves (1, 2). The insertion device (3) is used to keep a space free for the individual permanent magnets during the assembly process. By way of example, this allows the pole teeth to be wound without permanent magnets interfering with this manufacturing step. Permanent magnets are finally inserted into the insertion devices.

Abstract: The aim of the invention is to better adapt the power range of a linear motor to specific applications. For this purpose, the secondary part (2) is subdivided into at least one first (3) and one second section (4) in the direction of travel (15) of the primary part (1). The secondary part (2), in the first section (3), has a different shape than in the second section (4) and/or is produced from a different material. In this manner, different speeds of the primary part (1) can be achieved on the traveled distance independent of the actuation of the primary part. Optionally, cage windings can be inserted in a section of the secondary part so that said secondary part can be used for passive breaking.

Abstract: A side air-bag formed from two layers of fabric includes an internal tether extending from a fold-line in a region of the air-bag configured to receive a gas generator to a point on one of the layers of fabric. The distance around the periphery of the air-bag between the ends of the tether is greater in one direction than in the other direction. The length of the tether is less than the shorter of the two distances. The tether serves to assist in guiding the air-bag, on inflation, so that it extends forwardly from a vehicle seat to lie adjacent an occupant of the vehicle seat.

Abstract: The aim of the invention is to make person conveying systems more simple and less expensive. Said aim is achieved by equipping a person conveying system with a synchronous linear motor comprising a rack-shaped, permanent magnet-less secondary part (S) for driving purposes while the primary part of the synchronous linear motor is fixed to the conveying device (K) in or on which persons can be conveyed. If the person conveying system is embodied as a magnetic levitation railway, the synchronous linear motor makes it possible to conserve a significant amount of energy as opposed to an asynchronous linear motor as the permanent magnets provide a certain basic magnetic flux that can be used for supporting the railway car and driving the same in the direction of travel.
