Abstract: A method is proposed for distributed creation of a program for a programmable portable data carrier (10) e.g. a smart card. Program source text (Q) is created on a user computer (20), compiled and linked into executable program code (C) on a spatially separate compiler server (30), and the executable program code (C) loaded into data carrier (10) again via the user computer (20). A secure end-to-end link is set up for the data exchange between data carrier (10) and compiler server (30). For this purpose, the data carrier (10) is provided, in a precompletion step, with software tools for final processing that permit a transport code (U, CSSL, UCSM) provided in a transient format to be converted into executable program code (C). the transport code (U, CSSL, UCSM) is secured by encryption mechanisms. The transfer of the executable program code (C) generated by the compiler server (30) to the data carrier (10) is effected in the transient format (U, CSSL, UCSM).

Abstract: Disclosed are a method and a corresponding continuous casting machine ( 1 ) for continuously rolling a metal bar, particularly a steel bar, which is produced at a casting speed and the cross section of which is configured as a thin slab. Said metal bar is bent, dressed, and cut to length as required during cooling and is fed into a first roll stand for rolling once the temperature has been equalized. Optionally the metal bar can still be fed by modifying the casting machine by supporting ( 3 ) a vertically cast continuous slab ( 2 ) having a guide length that is adjusted to the casting rate. One or several segments of said continuous slab ( 2 ) is/are then dressed by bending and straightening, whereupon the continuous slab ( 2 ) is guided by a sling ( 11 ), which is supported from below, into a straightening driver ( 6 ) that is positioned at a distance approximately equivalent to the length of the sling before being cut to length ( 7 ).

Abstract: A conveyor belt for endless conveyor belt systems is laid in tight curve radii because the belt and the guide bar, which is attached to the underside of the belt, consist of highly elastic rubber. The belt is reinforced by preferably diagonally placed fabric inserts and can be pre-stretched in the longitudinal direction by means of a traction beam attached only at individual points so that it can do an optimum job in performing its transport function. The reversing rollers and the roller blocks are divided or are made up of individual units in order not to influence the guide bar, which runs in the middle, during the overrun. In this way, the necessary drive forces can attack at many corresponding places depending on the curve radius, without the conveyor as a whole, with a length of 100 meters and more, being subject to the so-called flip-arc effect. Instead, the curvilinear, decentrally powered conveyor belt is driven uniformly and is fed simultaneously, while one can achieve a high conveyor output also in the transfer area by means of corresponding troughing.

Abstract: On a cellular wheel (4) which can be driven in such a way as to rotate about a central shaft (5) there are arranged cells (35) which are separated from one another by means of spokes (33). On the spokes (33) there are fastened blades (36) in such a way that each cell (35) is delimited on two opposite end faces of the cellular wheel (4) by one blade (36) in each case. At each end face of the cellular wheel (4) there is arranged at least one stationary counterblade (39) which interacts with the rotating blades (36). The cellular wheel (4) is subdivided, in a plane (40) which is normal to the central shaft, into two cellular wheel halves (4', 4'') which are in each case mounted on a bearing box (32). The two bearing boxes (32) can be adjusted with respect to one another along the central shaft (5). The counterblades (39) participate in adjustment, as they are in each case supported by one of the bearing boxes (32). As a result of this, the device can, by means of relative adjustment of the two cellular wheel halves (4', 4''), be adapted in a simple fashion to products to be trimmed of different formats. <IMAGE>

Abstract: The method should make it possible to exchange data with each individual or one of a multiplicity of objects with little technical expenditure. An antenna arrangement (5) present on the base station repeatedly receives signals radiated by all objects located within a predetermined region.

The location information is used for controlling a beam forming network (6) connected to the antenna arrangement (5), in such a manner that the antenna arrangement (5) generates for each of the objects a directional pattern which is formed in such a manner that a main receiving lobe is directed towards the relevant object and the reception attenuation is high in the direction of in each case the other adjacent objects in comparison with the main receiving lobe. <IMAGE>

Expediently, two resistance elements (52, 54) controllable independently of one another are provided, one of which covers the bottom (21') of the vessel overall, while the other surrounds the lateral surface (21'') of the vessel over its entire height. The respective resistance element (52, 54) is regulated by the control device (55) in such a way that the vessel wall and thus the milk does not exceed an adjustable maximum temperature of between 70 and 75 Celsius during heating up and the heating output is reduced when a wall temperature of between 50 and 70 Celsius is reached. With this heating device (50) according to the invention, on the one hand the milk is heated and kept warm with less expenditure of energy on account of the direct heat transmission and, on the other hand, the heating temperature can be precisely controlled in a very simple way, with the result that overheating of the milk in every heating phase is strictly avoided. <IMAGE>
