Abstract: Some embodiments disclosed herein relate to a method. In the method, a duration of a first synchronization pulse is measured. A fixed, predetermined number of ticks are equally spaced at a first time interval over the first sync pulse, regardless of the duration of the first synchronization pulse. A duration of a first data pulse is then measured by periodically incrementing a tick count value at the first time interval during the entire duration of the first data pulse. The tick count value at an end of the first data pulse is then correlated to a first digital value encoded on the first data pulse.

The securing section (10) of the coupling part (7) are crimped to the free end section (11) of the spindle (1). The invention also relates to a connecting method.

Abstract: A method for allocating bus access rights is used in a multimaster bus system wherein addresses are explicitly allocated to master devices and each master device is assigned a priority value from an organized priority list of priority values. Requests from at least one master device to use the bus system to access a slave device are received, and the priority values of all requesting master devices are compared. If a sole requesting master device has the highest priority value access to the respective slave device is granted to that master device. If a plurality of requesting master devices have the same highest priority value access is successively granted to the requesting master devices having the same highest priority value on the basis of the address allocation of the master devices.

Abstract: The present invention relates to three-dimensional catalyst gauzes for gas reactions knitted in two or more layers from noble metal wires in which the meshes of the individual layers are joined to one another by pile threads. In these catalyst gauzes weft threads are inserted between the mesh layers. These catalyst gauzes have an increased catalytic activity and efficiency in gas reaction. These improvements enable operation with a lower total amount of noble metal employed, for example by reducing the number of gauzes and/or the length of the wire processed in the catalyst gauze and/or the wire thickness, without thereby having to accept disadvantages with respect to the yield and selectivity of the gas reaction, mechanical strength and service life of the gauzes or unavoidable loss of noble metal.

Abstract: Three-dimensional knitted catalyst gauzes made from noble metals have recently come into use for ammonia oxidation and other gaseous reactions. Particularly high yields accompanied by a stable course of the reaction and an extended service life of the catalyst gauze are achieved if the catalyst gauzes are knitted in two or more layers and the layers are connected together by pile threads. Important features are the largest possible number of pile threads per unit area and the alignment thereof as parallel as possible to the direction of flow of the reaction gases.

Abstract: A rotary tablet press has a rotating mold table and top and bottom plungers, which can move reciprocally in plunger guides, coaxially with the molds. The reciprocating motion of at least the bottom plungers is cam-controlled and these plungers are acted upon by a damping element to prevent an overshoot of their movement. To ensure an action which is as free from wear and is as maintenance-free as possible whilst maintaining constant damping of the bottom plungers, it is proposed according to the invention that the damping element consists of at least one magnetic element which acts on the plungers.
