Title: Immersion pump with axially sliding rotor - has pipe for connecting inlet and thrust bearing for thrust compensation
Inventor: BARTELS HENNING G DR ING
IPC: F04D15/00
Filed: 1975-08-02
Abstract: The submerged pump has pressure compensation feature for improving its consistency. This centrifugal pump rotor rotates about a horizontal axis. On the extended shaft of the motor is arranged an axially sliding rotor. The performance is improved by a connection pipe between the rotor entry end and the sealed chamber behind and thrust bearing. The OD of the axially sliding thrust bearing is approximately equal to the inlet diameter of the rotor. A pressure gauge or flow rate measuring instrument or a metering instrument is fitted into the tubular pump for controlling its functioning. Pressure compensation by connection pipe eliminates the need for pressure compensation rings on the rotor and improves pump efficiency. Water is hence transferred from the inlet to the sealed space behind the thrust bearing plate. On pumping the floating shaft is pushed towards the inlet end.

Title: Preventing propagation of cracks in pipes - by intermediate ring with transverse metal texture welded into pipe
Inventor: MARCI GUENTER DR PHIL
IPC: F16L57/02
Filed: 1977-02-01
Abstract: A device for limiting the length of cracks in a pipeline consists of an intermediate ring or rings welded into the pipe, each ring being of the same material as the rest of the pipe but having its rolling or forging texture oriented perpendicularly to that of the main part of the pipe. Pref. the intermediate ring is thicker than the remainder of the pipe, with a gradual transition from the standard pipe thickness to the increased thickness of the ring itself. Used in particular for pipes and ducts in nuclear power plant, to prevent the propagation of brittle fractures along the pipe. With nuclear power plant, in particular, diffulties arise if other conventional methods of preventing crack propagation, such as jackets or reinforcing sleeves around the pipe, are used. These impede access for routine testing and surveillance. The method obviates this difficulty and enables the entire pipe to be inspected.
