Abstract: An eccentric screw pump has a plurality of segments extending along an axis and together forming a tubular casing generally centered on the axis and a plurality of axially extending stator shells of elastic material together forming inside the casing a tubular stator having axially opposite ends each having centered on the axis a frustoconical end seal surface. The stator shells are separable from the casing segments. An intake housing has a connecting flange formed centered on the axis with a frustoconical flange surface fitted with one of the end seal surfaces of the stator, and an output fitting has a connecting flange formed centered on the axis with a frustoconical flange surface fitted with the other of the end seal surfaces of the stator. A rotor extends axially in the stator, the stator being clamped by the casing against the rotor.

Abstract: Eccentric worm pump with at least one stator (1) composed of an elastic material and a rotor (2) which is mounted in the stator (1), wherein the stator (1) is surrounded at least in certain areas by a stator casing (3), characterized in that the stator (1) is in the form of a longitudinally split stator which is composed of at least two stator component shells (1, 1b).

Abstract: A swing trailer having a first plate rotatably attached to a second plate and a foot placement device on top of the first plate, and a first stop on the first plate and a second and a third stop on the second plate. The engagement of the first stop with the second and third stops limit rotation of the first and second plates to approximately 90°.

Abstract: A computer-based drawing number system is provided that coordinates the request for information about drawing numbers, the issuance of new blocks of drawing numbers, and searches for drawing numbers. The drawing number system may include an exact number component, a search component, an update component, an issue block component, a web engine component, a server engine component, and a variety of databases. The exact number search component may be used to search for information about a particular drawing number, and the search component may be used to search for drawing numbers when the exact number is not known. The issue block component may be used to issue the next available block of drawing numbers to a requester. The drawing number system may accommodate other types of document numbers besides drawing numbers. The drawing number system may be implemented in a client/server environment, such as a web-based environment over the Internet.

The drawing number system may include an exact number component, a search component, an update component, an issue block component, a web engine component, a server engine component, and a variety of databases. The issue block component may be used to issue the next available block of drawing numbers to a requester. A branch bank computer may be used to request new blocks of drawing numbers and to distribute those drawing numbers to users when requested to do so. The drawing number system may accommodate other types of document numbers besides drawing numbers. The drawing number system may be implemented in a client/server environment, such as a web-based environment over the Internet. In such an environment, a web server provides the various components of the drawing number system.
