Abstract: A method for operating a processing machine, in which a first web section of a product web is delimited by closing a first clamping point and a second clamping point, such that a first web tensile force prevails in the web section. A third clamping point within the first web section is closed, so that a second web section is formed between the first clamping point and the third clamping point. At least one of the closed third clamping point and the closed first clamping point are adjusted by an angle, so that a second web tensile force in the second web section is changed, preferably increased.

Abstract: An actuator for a speed governor of an elevator system includes a governor wheel equipped with at least two flyweights. The governor wheel can be driven by a governor cable looped around it. An actuator wheel is stationary in a basic position. A coupler engages the actuator wheel when the governor wheel attains an actuation speed and thus couples with the governor wheel so that the actuator wheel is caused to rotate. An elastic material, preferably transmitting a high degree of friction, is provided between the coupler and the actuator wheel. The actuator wheel has a lining or tire of the elastic material and/or the coupler is equipped with the elastic material.

Abstract: One or more dynamic logon group parameters can be retrieved. The dynamic logon group parameters can be associated with an originator of requests for server processing by a computing system that includes a plurality of server instances, can be established prior to runtime, and can include an abstract definition of server instance characteristics required or preferred for handling the requests from the originator without designating specific server instances for handling the requests from the originator. One or more server instances can be selected from the plurality of server instances such that the one or more selected server instances satisfy the abstract definition of server instance characteristics. At runtime, the one or more selected server instances can be assigned to respond to the requests from the originator. Related articles of manufacture, systems, and methods are described.
