Title: Magnetic test (search, exploring) coil arrangement for scanning flat and curved surfaces from electrically conductive test specimens in conjunction with the application of the eddy-current method
Inventor: WITTIG GUENTHER DR ING
IPC: G01N27/90
Filed: 1981-07-11
Abstract: In the case of the application of the pulsed eddy-current method in nondestructive testing, in accordance with the prior art use is made, for the purpose of localised scanning of test specimens and of generating the signals, of coil systems in which the principal axes of the field-exciting coil and of two measuring coils are arranged in parallel and are perpendicular to the test surface. Because of the unavoidable irregularities in the two windings, there are difficulties in practice in bringing about a balance between the signal voltages connected in series when there is no disturbance of the eddy-current field - e.g. due to a material defect. The essential feature of the coil arrangement according to the invention is a field-exciting coil whose axis is likewise perpendicular to the surface of the test specimen, and a measuring coil whose axis is arranged parallel to said surface. The measuring coil in this arrangement is laterally displaced and tangentially aligned with respect to the excitation coil (see sketch). Components of the exciting magnetic field coincide only to a slight extent with the direction of the principal axis of the measuring coil, with the result that balancing is substantially facilitated. <IMAGE>

Title: Method and apparatus for the skin turning of metallic bars and tubes
Inventor: WECK KARL-GUSTAV
IPC: B23D1/26
Filed: 1981-10-31
Abstract: The invention relates to skin turning machines for bars and tubes (17, 29, 43, 76). It is proposed to temporarily accelerate the workpiece, which has been finish-skin-turned but is still in the skin turning machine, in order to obtain a gap between it and the workpiece (29) closely following it. Just before the finish-skin-turned workpiece leaves the skin turning machine, the axial velocity is reduced. The workpieces thus pushed out carefully are slightly dispersed with regard to their axial position after leaving the skin turning machine. The acceleration and braking of the withdrawal roller pair (3) is effected via a direct-current motor (4) which is controlled via a pulse generator (6) and one or two length-measuring devices (5, 78). In addition to the withdrawal roller pair (3), a clamping carriage (32) can be provided (Fig. 2). As an alternative to the direct-current motor (4), a transmission connection (in Fig. 3) is provided between the push-in unit (1) and the withdrawal roller pair (3), which transmission connection is equipped with several couplings (61, 62, 63) and operating stages (59, 67). <IMAGE>

Patent DE-3146172-A1 (DE)
Title: Propulsion system for vessels
IPC: B63H11/10
Filed: 1981-11-21
Abstract: A propulsion system for vessels is proposed which serves to improve the manoeuvrability of ships of any type. The system comprises a vertically arranged rudder blade (14), the rotational axis (19) of which passes transversely through the jet axis of the propulsion jet. Allocated to this vertical rudder blade (14) is a further, horizontally arranged rudder blade (15), the horizontal rotational axis of which is likewise arranged transversely to the propulsion jet and at right angles to the rotational axis (19) of the vertical rudder blade (14). The ship can be manoeuvred on the spot by adjusting these two rudder blades (14, 15) without the propulsion having to be changed over or switched off. This is done, for example, by a transverse setting of the vertical rudder (14) in combination with an angular setting of the horizontal rudder (15). The propulsion jet can be directed in any direction important for manoeuvring a ship by adjusting the rudder blades (14, 15). <IMAGE>

Title: Heat exchanger laid in the ground
Inventor: SPIEGEL WERNER DIPL ING
IPC: F28D7/08
Filed: 1981-12-12
Abstract: In the heat exchanger laid in the ground, a multiplicity of long heat exchange tubes (3) laid parallel in the ground with a mutual spacing and the interposition of distributors (4; 5) are connected a supply pipe (1) laid in the ground and to a return pipe (2) laid in the ground. Each individual distributor directs the heat transfer medium, principally consisting of water, into a group (6) of a plurality of heat exchange tubes, or extracts it therefrom. In order under the different temperature conditions that occur to avoid high stress loading of the ductwork, or to achieve risk-free strain compensation, the ductwork is constructed such that the transverse dimension (q) of the distributors (4; 5) is small in relation to the transverse dimension (Q) of their heat exchange tube group (6), and the individual exchange tubes (3) are constructed curved in their end sections (7; 8). The heat exchanger is suitable as a cooling system for power stations, the ground being heated, and it being possible to use the waste heat from the power station for agricultural purposes. It can also be used in conjunction with heat pumps, the thermal energy extracted from the ground being used for heating purposes in buildings. <IMAGE>

Title: Pasteurization plant
Inventor: BREUNING ERNST DR ING
IPC: A61L2/04
Filed: 1982-03-26
Abstract: The invention relates to a pasteurization plant for liquids which are initially heated, filled into vessels in a Fuller and then cooled again. It comprises a heat exchanger and a cooling tunnel which in turn has at least two zones for irrigation of the vessels with water, a water-permeable transport belt (1) and irrigation reservoirs (2, 3) present in the zones, as well as collection reservoirs (4, 5) below the transport belt (1) and delivery pumps (6, 7) and, according to the invention, a passage pipeline system (8, 9) located in the collection reservoirs (4, 5) by means of which the heat withdrawn from the vessels during the cooling process is fed to the liquid which is still cold and flows through the pipeline system (8, 9). The heat which cannot be withdrawn from the irrigation water merely by this means is carried away to the outside, according to the invention, by a freshwater stream guided through all irrigation reservoirs (2, 3) and collection reservoirs (4, 5) and finally through the overflow (11) from the collection reservoir (5) through which the water flows last. Introduction of the freshwater stream in an irrigation reservoir part which is separated, according to a further development of the invention, from the irrigation reservoir (2) through which the water flows first by a partition (13) increases the efficiency. The invention permits considerable savings of heat and fresh water coupled with a low technical outlay. <IMAGE>
