Abstract: A coating system has, in a housing (1), a sputtering chamber (3) for the coating of a substrate (22) and a target carrier coating chamber (4) for the continuous coating of a rotating target carrier (2) with a coating of target material (25), which projects into both chambers (3, 4). The surface of the carrier which has been coated in the target carrier coating chamber (4) passes continuously through the sputtering chamber (3). The previously produced coating forms the target for the sputtering process in the sputtering chamber (3).

Abstract: A method is proposed for controlling a reactive sputtering process wherein the working point on the physical characteristic curves, cathode voltage or working current intensity over reactive gas flow to the sputtering apparatus, defined by the value of one of the two factors determining the electrical power drain of the reactive sputtering process, is adjusted and maintained constant by metering the reactive gas, for example O.sub.2, to the process chamber. Further, the invention proposes a device for the practice of the method, wherein a sputtering apparatus is provided, comprising a controller 5 (reactive gas controller) and a control valve 8 for metering the reactive gas. Further, a signal line 15 is provided which carries the cathode voltage to the input of the controller in which the output of the controller is connected to the control valve via a line 16 which supplies the adjusting magnitude computed in the controller to the control valve.

Abstract: When a differential speed determined from the wheel speeds has superimposed thereon a frequency typical of drive train vibrations, a vibration signal is generated. When the vibration signal exceeds a threshold, a torsional moment based on the difference between the engine speed and the differential speed is used to modify activation times of the brake pressure control valves so that the drive train vibrations decay.

Material for the capillary transport of a liquid sample defines a sample application zone and a plurality of sample withdrawal zones connected to said application zone by a like plurality of transport paths. At least one of said paths has a retardation zone which assures that liquid applied to said application zone arrives simultaneously at said withdrawal zones, regardless of the lengths of the paths.

Abstract: A substrate carrier plate (17, 17a) designed to hold at least one substrate is removably attached to a support element (19, 19a) of a base (2). The carrier plate is held to the support element (19, 19a) at least at one point by a centering pin (22, 23; 22a, 23a), which projects from the plate of the support element (19) and fits into a hole (24, 25) in the substrate carrier plate (17), and at least at one other point by a clamping device (18, 18a). The clamping device (18, 18a) is held on a control part (11) on the base (2) in such a way that it can be moved by the displacement of an actuating arm (21) between a clamping position and a release position, and it is also provided with a tensioning roller (14), which is supported on a ramp (15, 15a) on the substrate carrier plate (17). The substrate carrier plate (17) has an opening (20, 20a) to allow the passage of the tensioning roller (14), the tensioning roller (14, 14a) being located behind this opening when in its release position.

Abstract: The invention describes peptides derived from tumor rejection antigen precursor MAGE-2. These peptides bind with HLA-A2 molecules, thus presenting complexes which provoke cytolytic T cell production. The resulting "CTLs" are specific for complexes of HLA-A2 and the peptide. The complexes can be used to generate monoclonal antibodies. The cytolytic T cells produced may be used in the context of immunotherapy, such as adoptive transfer.

Abstract: Tumor rejection antigens derived from tumor rejection precursor MAGE-3 have been identified. These "TRAS" bind to the MHC-class I molecule HLA-A2, and the resulting complexes stimulate the production of cytolytic T cell clones which lyse the presenting cells. The peptides and complexes may be used diagnostically, therapeutically, and as immunogens for the production of antibodies, or as targets for the generation of cytolytic T cell clones.

The carrying case has a compartment for the telephone shields and a compartment or two for carrying coins or tokens for use in a public telephone. Where a reusable telephone shield is used, the compartment is provided with a raised portion which sandwiches the reusable shield between layers of disinfectant material, which disinfect the shield between uses.

Abstract: When a first drive wheel is braked as a function of slippage at that wheel, braking intervention at the second drive wheel is precluded until the braking intervention at the first drive wheel is essentially terminated. This produces a locking differential effect.

Abstract: The slip of at least one driven wheel is compared to a predetermined threshold and the wheel is braked or torque is reduced when the threshold is exceeded. The slip threshold is raised when an impermissible difference between diameters of the tires on driven wheels is detected.

Abstract: A predrawn can made of a metal sheet coated with an organic film is subjected to a process which reduces its diameter and thins its walls by a high thinning ratio. The thinning is achieved by a blank holder (1), a redrawing die (3) and an ironing die (4), the reduction ratio for the ironing die being defined by ##EQU1## wherein T.sub.2 equals the thickness of the can before ironing and T.sub.3 equals the thickness after ironing, wherein the reduction ratio for the ironing die is in the range of 10 to 50%. The wall at the top end portion of the can is maintained thicker than the rest of the can wall.

Abstract: First and second signals representing unevenness of the roadway are generated for at least one wheel, and brake pressure is controlled using control parameters based on the second signal. The first signal is compared to a first threshold which is dependent on the second signal, and an extreme value signal which represents large impacts on the vehicle is generated when the threshold is exceeded. The control parameters are then adjusted so that the channels for controlling brake pressure at each controlled wheel are less sensitive.
