Title: Silicon cast iron heat exchanger for hot sulphuric acid - having construction resisting thermal stress damage
IPC: F28F21/08
Filed: 1980-12-10
Abstract: A large heat exchanger for hot sulphuric acid is pref. made of silicon cast iron as three concentric tubes with inner and outer flow channels. The inner and outer tubes are in cylindrical sections meeting in annular curved flanges with intermediate sealing rings, e.g. in grooves. The central tube may be formed of fleshly mating cylinders but is pref. in section with helical internal and external webs to form the inner and outer flow channels, or a corrugated helical tube producing labyrinthine flow channels. The tube sections are interconnected by tie-rods with independently acting resilient tensioning springs or clamps. Construction is resistant to thermal stresses, esp. during temp. changes, which might prejudice the inherently good corrosion resistance of the alloy, in partic. when combined with casting stresses.

Title: Device for scram shutdown of a nuclear reactor as a function of the coolant pumping function
Inventor: ROEGLER HANS-JOACHIM DIPL PHYS
IPC: G21C7/12
Filed: 1981-03-19
Abstract: In order to shorten the delay time between the occurrence of a fault in the power supply (4) of the coolant pumps (3) and the triggering of scram shutdown by the de-excitation of an electromagnet (9), it is proposed to monitor the current or the voltage of each of the phases of each individual coolant pump (3) with the aid of all-or-nothing relays (11) which are closed in normal operation but open in the event of power failure and thus interrupt the power supply (10) of the electromagnet (9). The armature (8) held against the latter is released, and the absorber rod (7) suspended thereon can drop into the core (2) and shut down the nuclear reactor. <IMAGE>

Title: Elongate, compressible container, having a circular or approximately circular cross-section, e.g. tubular container, such as a tube, sleeve or the like and method of manufacturing the latter
Inventor: GEIGER ROLF
IPC: B29D23/20
Filed: 1981-05-16
Abstract: Elongate, tubular containers, such as tubes, sleeves or the like, having a container body made of a sheet of paper or lightweight cardboard or possibly impregnated fabric have a conical or virtually conical shape and on the inside an inside protective coating and, on the outside, a protective and decorative coating, the mutually overlapping edge parts of the sheet being connected to one another by sealing, hot-sealing, welding or bonding. At one end, the container body is closed by a head piece of environmentally friendly material, for example chemical pulp, cellulose, etc., which can be mounted, for example bonded or welded or sealed or sprayed, onto the container body at a later date. At the other end, the container body is sealed by a tight connection of the wall ends. The container body can have a longitudinal seam extending parallel to the longitudinal axis of the body if it is produced by single or multiple rolling, wrapping or folding, in which case it can possibly also be distended or shrunk to produce a conical shape. It can also have a seam winding helically around the longitudinal axis of the body if it is produced by helical wrapping of the sheet around a cylindrical or possibly even conical core. The new container can be produced item by item or even continuously, for example in tubular form, the individual container sections then being produced by cutting to length.

Title: Method for correcting image errors (aberrations) caused by an inhomogeneous distribution of sound velocity and/or errors in the position-determining elements of a scanning device in the ultrasonic scanning of objects, in particular in ultrasonic reflection computer tomography and the compound-B scanning method
Inventor: HUNDT ECKART DR DIPL PHYS
IPC: A61B8/14
Filed: 1981-07-09
Abstract: The distortions in scale which occur during imaging due to echo-time effects because of different sound velocities inside the object region and/or errors in the position-determining elements are corrected by making use of at least one prominent region of the object to determine a respective translation of a partial image before the superimposition of partial images to form a total image, with the result that this respective region is sharply imaged by means of the translation carried out, and due to the fact that partially differing sound velocities are adopted for the purpose of reconstructing the image of the relevant object region from the ultrasonic signals. <IMAGE>

Patent DE-3217355-A1 (DE)
Title: Heating boiler
Inventor: SEIDL FRANZ DIPL ING
IPC: F24H9/00
Filed: 1982-05-08
Abstract: This heating boiler is distinguished by very small radiation losses and by a uniform heat distribution of high temperature on the combustion chamber wall. Higher overall efficiency is achieved by an inner wall arranged in the jacket of the convector in order to form an outer and an inner jacket. The return flow flows exclusively through the outer jacket and receives the radiating heat from the inner jacket. The return flow water which flows through the outer jacket is fed into the inner jacket at the hottest point of the heating boiler and is mixed with the very hot water surrounding the combustion chamber, and is forwarded to the fore-runnings. The high thermal effect is achieved by a very simple, rationally producible design.

Title: Adjusting device for a thermal excess-current trip device
Inventor: PRASSE FRANK DIPL ING
IPC: H01H71/74
Filed: 1982-12-09
Abstract: The invention relates to the field of low-voltage protection switches, especially motor protection switches. The object is to modify the adjusting device of thermal excess-current trip devices in such a manner that the adjustment movement including the scale is increased, and the handling and identification capability are hence significantly improved, at the same time it being ensured that the transformation between the adjustment and the tripping movement of the tripping elements is increased and the influences of geometrical deviations and adjustment errors are small, so that conformity to the tripping characteristic is achieved at a low cost. This object is achieved in that an adjusting slide, which is guided in a straight line and is located parallel to the operating plungers, is arranged on a sliding rail which is connected to the board of the switch mechanism and whose adjustment movement corresponds to a significant region of the switch width. The adjustment slide corresponds with an incline which is matched to the displacement movement and can be integrally formed directly on both a bend in the holder as well as on the adjusting slide. <IMAGE>
