Abstract: A fluid treatment device has an exchangeable treatment unit and a connection head. A bayonet-type connection device connects connection head and treatment unit to each other by a plug-in/rotation movement about a connection axis of the treatment device and is provided with a housing connection part and a head connection part that operatively engage each other to form a connection of the bayonet-type connection device. Housing connection part and head connection part each have a mutually complementary functional element extending circumferentially about the connection axis and operatively connectable to each other. The bayonet-type connection device has a pretension element for realizing a mechanical pretension pressing the functional elements against each other. A splash guard part is provided that covers at least the connection device.

The bayonet-type connection device has a pretension element for realizing a mechanical pretension pressing the functional elements against each other. The pretension element is a spring element with outwardly projecting spring arms with radially outer end faces provided with a straight section that is tangential to a rim extending in circular shape around the connection axis.

Abstract: A fluid treatment device has an exchangeable treatment unit and a connection head. A bayonet-type connection device connects connection head and treatment unit to each other by a plug-in/rotation movement about a connection axis of the treatment device and is provided with a housing connection part and a head connection part that operatively engage each other to form a connection of the bayonet-type connection device. Housing connection part and head connection part each have a mutually complementary functional element extending circumferentially about the connection axis and operatively connectable to each other. One functional element has an assembly ramp passing into a first support region perpendicular to the connection axis. The other functional element has a slide region adjoined by a second support region perpendicular to the connection axis. In connection end position, first and second support regions are positioned on top of each other relative to the connection axis.

Abstract: A crankcase ventilation valve comprises a membrane element with a metal support washer and a conical spring, the end face of which acts on the support washer.

Abstract: A method, system, and computer-program product for effecting incremental changes to a repository are disclosed. The method includes receiving an incremental feature package and applying the one or more revisions to the repository. In such methods, systems, and computer-program products, the incremental feature package includes one or more revisions to be made to a repository.

Abstract: A method of and an apparatus for optimizing timing delay and power leakage in a circuit. The apparatus determines at least one path of a plurality of paths in a network of logic elements, the at least one path including a plurality of cells, each of the cells being configured to perform a logical operation. In addition, the apparatus identifies a first cell of the plurality of cells based on a first cost factor associated with replacing the first cell with a first replacement cell that performs the same logical operation, the first cost factor being a function of a power leakage difference and a timing delay difference associated with the first cell and the first replacement cell. Furthermore, the apparatus replaces the first cell with the first replacement cell in the at least one path.
