Date Feb. 21, 1991.In a method for sensorless control of a reluctance motor the actual magnetic flux is compared with tabulated values of the non-linear function between the magnetic flux and the current for the angular position at which a commutation signal (via P15-P18) is to be emitted to the power stages (1-4) for the stator pole windings (H10-H13) of the motor. The actual value of the magnetic flux is calculated for each sample interval, based on the sampled values of voltage (u via P7) and current (i via P8) according to the relation  DELTA  PSI =(u-R.i) DELTA t, where R is the resistance of the actual pole winding and the actual power stage. The instantaneous flux value  DELTA  PSI  received is added to the value of the magnetic flux previously received. The added value constitutes the actual value, referred to above, which is to be compared with tabulated values.

Abstract: A description is given of a turning device (10) for conveying sections, in particular for a strapping machine (12), the turning device (10) having a support (24) and a turning table (28). The turning table (28) is arranged on a vertically aligned lifting shaft (34) which is provided on a drive device. The drive device has three crank elements (44, 46, 48) of equal length, which are aligned parallel to one another in each drive position. The three crank elements (44, 46, 48) are arranged, with their respective first end section, on a drive shaft (56) of a drive motor (58) or on stationarily provided bearing shafts (60, 62). The opposite second end sections of the crank elements (44, 46, 48) are rotatably connected by means of connection shafts (50, 52, 54) to a common connection element (42) with the result that a parallel crank drive results. Rotatably mounted on the connection element (42) is a lifting shaft (34). Provided between the lifting shaft (34) and a stationary point on the turning device (10) is a rotating device (92), with the aid of which the lifting shaft (34), while executing a circular movement (82), carries out a swivelling movement about the central centre line (38) of the lifting shaft (34) in a first plane (80). <IMAGE>

Abstract: A device is proposed for applying material such as solder paste and glue in discrete points, particularly for applying solder paste on electronic circuit boards. The device comprises a pump house (202-205; 301, 307), a tube or a channel (206) by means of which material is fed to the pump house, a nozzle (111, 205) for feeding material from the pump house (202-205; 301, 307). Suitable upper and lower valve devices are arranged to block, at predetermined times, the feeding of material to and from the pump house (202-205; 301, 307). The lower valve device may possibly be replaced by a restriction device. As is conventional the pump house (202-205; 301, 307) comprises an outer pump cylinder (203; 307) and an inner piston (204; 301). The displacement of the piston (201; 301) is obtained by the fact that the piston is connected to a magnetostrictive rod (202; 308). This rod (202; 308) cooperates with a coil (208) arranged around the rod (202; 308). When an electric current is fed to this coil (208) the length of the rod will increase. A very rapid application of the material is achieved.

Abstract: A heat exchanger element comprises three parallel tubes (11), which to a considerable part of their lengths are cast into a body (12) of a metal having good heat transferring properties and having a rectangular cross section. Within the portion of the tubes (11) enclosed by the body, the tubes are externally provided with helical rills (15), running in opposite directions, and are interconnected by tack welding outside the expected body, before the casting operation.   The side faces of the body (12) are subdivided by means of transverse and longitudinal grooves (18, 19a, 19b), so heat transferring enlarging members (17) as truncated pyramids are formed. Members in adjacent rows are displaced sidewardly, so a zig zag pattern is formed, which causes turbulence in the second heat transporting medium flowing along the body. <IMAGE>

Abstract: In a method for matching two images, each consisting of a plurality of pixels and having partially overlapping contents, the degree of correspondence between the contents of the images is determined for different displacement positions representing different overlappings of the images. More specifically, a plurality of numbers are determined for each one of a plurality of said displacement positions. Each number is formed with the aid of pixel values from both images and is used to simultaneously retrieve predefined overlap assessment values for at least two of said displacement positions. The overlap assessment values retrieved are subsequently used to determine the degree of correspondence between the images for the different displacement positions. The method is carried out with the aid of a computer and can be implemented as a computer program.
