摘要:
Data entities in a client-server system are accessed. The client-server system comprises a set of clients, a server system, and a repository for storing a plurality of data entities. The server system comprises an inter-transactional cache, the inter-transactional cache being accessible for each client of the set of clients. A first client of the set of clients comprises a first intra-transactional cache. If a copy of a first data entity is in the inter-transactional cache, a version identifier of the original first data entity is read from the repository. If the copy of the first data entity is to be accessed with an exclusive lock, a copy of the copy of the first data entity is added to the first intra-transactional cache. The copy of the copy of the first data entity in the first intra-transactional cache is accessed for further processing of the first data entity by the first client.
摘要:
A drive device for erosion tools, having a drive shaft, an electrode holder connected to the drive shaft, an axial drive which works on the drive shaft, a rotational drive which works on the drive shaft as a direct drive in a contactless manner, and a radial bearing. The radial bearing is constructed as a ball track.

摘要:
The invention relates to an extruder system for extruding a fluid with at least one supply device, at least one mixer device and at least one extrusion die. In accordance with the invention at least one device for producing a fluid flow (transport fluid) that completely or partially surrounds the material to be extruded that essentially runs parallel to the outlet direction of the material to be extruded is provided, and whereby the fluid is discharged from the extruder system by suction and/or pressure of the transport fluid flow by means of an expulsion gas. The extruder system allows even product discharge for products well into the nanometre range.
摘要:
An x-ray tube has a stationary vacuum housing, in which are arranged an electron-emitting cathode and a ring anode with an impact surface on which the electron beam, accelerated by an electrical field, is incident, as well as a deflection system to focus and deflect the electron beam. The ray exit window of the x-ray tube is round, lies in the plane perpendicular to the central axis of the x-ray tube, and terminates one side at the vacuum housing. The impact surface of the ring anode is beveled and is aligned to the ray exit window. A diaphragm is provided in front of the ray exit window that defines a circular opening for the x-ray radiation. The ring anode is surrounded by an annular anode cooling arrangement.

A plug-in connection for the connection of tube and hose lines, in particr for use in tube-line systems of motor vehicles, consists of a male part (S), on which is provided a clip receiving locking groove, a female part (A), into which the male part can be sealingly inserted and on which female-part cavities are provided, with which the locking groove can be axially aligned. The locking of the male part (S) and the female part (A) is obtained by means of a locking clip.To achieve a long lifetime for the plug-in connection even under changing loads and to achieve a simple handling and inexpensive manufacture, the legs (28, 29) of the locking clip (St.sub.1) can be spread apart by an elastic deformation and can be maintained in the spread-apart position disengaged from the male part locking mechanism. Between the female part (A) and the male part there is arranged a spring (F) which guyes these parts in an axial direction with respect to one another. A seal ring (D.sub.1) is furthermore arranged in a peripheral groove (20) on the male part (S), which seal ring rests sealingly on a cylindrical inner surface (6) of the female part (A).

A first client of the set of clients comprises a first intra-transactional cache. If a copy of a first data entity is in the inter-transactional cache, a version identifier of the original first data entity is read from the repository. If the copy of the first data entity is to be accessed with an exclusive lock, a copy of the copy of the first data entity is added to the first intra-transactional cache. The copy of the copy of the first data entity in the first intra-transactional cache is accessed for further processing of the first data entity by the first client.
