Patent DE-3739614-A1 (DE)
Title: Twin fuel filter
Inventor: PRINZ NORBERT
IPC: B01D35/12
Filed: 1987-11-23
Abstract: Known twin fuel filters may, in spite of the arrangement of two filter cartridges, cause a drop in performance or stoppage of a downstream engine if they are blocked (plugged) especially by flocculant precipitation of paraffin at low ambient temperatures. The object of the novel filter is to avoid this. The novel twin fuel filter has a pressure-relief valve (24, 25) which is integrated into the cock plug (2) and which, if a certain excess pressure of the fuel in the fuel inlet (14) with respect to the fuel in the fuel outlet (15) is exceeded, short-circuits the inlet (14) and the outlet (15) so as to circumvent the filter cartridges (11, 12). This ensures that the fuel in case of blockage (plugging) of the filter cartridge(s) can flow directly, circumventing them, from the fuel inlet to the fuel outlet, thus ensuring continuous operation of the associated engine. The novel twin fuel filter is particularly suitable for continuously operating stationary diesel engines, e.g. for driving building machinery, pumps, generators and the like. <IMAGE>

Title: Method for the production of a fuel arrangement having wire spacing elements
Inventor: SHIBAHARA ITARU
IPC: G21C21/00
Filed: 1987-11-30
Abstract: The invention relates to a method for the production of a nuclear fuel arrangement of the type having spacing wire, which is constructed by arranging a number of fuel elements uniformly, spacing wires being wound around the fuel elements in a screw shape and these fuel elements being arranged in a sheathing pipe, the spacing between the adjacent fuel elements being held by the wires to a predetermined value and the method making it possible in a reliable way to prevent the occurrence of scratches on the fuel elements and to improve the lifetime of the fuel arrangement. The method comprises the steps that two-dimensional co-ordinates of one porosity per ring in the interior of a fuel element bundle and the flexibility of the fuel element are prepared, the occurrence and non-occurrence of scratches on the fuel elements are plotted on the co-ordinates, in order to determine a region of the non-occurrence of scratches around which the dimension of each section of the fuel element arrangement is determined, so that each measurement lies inside the region of the non-occurrence of scratches.

Title: Arrangement for the total reflection of X-radiation
Inventor: MIERSCH HELFRIED DIPL PHYS
IPC: G21K1/06
Filed: 1988-02-16
Abstract: The method for the total reflection of X-radiation is used inter alia for the monochromatisation of long-wave radiation in X-ray spectrometers with parallel beam path. By inserting an arrangement with a plurality of single mirrors arranged in plane-parallel manner at specific distances above one another, the loss of brightness caused by the very small limiting angle (angle of incidence) is compensated. Arrangements of this type can be compared with collimators which exert additional monochromatising effect and influence the spectrum qualitatively.

Title: Multistage process for removing solvents contained in a gas
Inventor: HOEHNE GERT DIPL ING
IPC: B01D53/047
Filed: 1988-03-25
Abstract: The invention relates to a multistage process for removing solvents contained in a gas in which removal of the solvent as far as possible without loss is ensured. This is achieved by the combination of the compression, condensation and pressure swing processes known per se to give a multistage process, virtually the entire amount of solvent being separated out by condensation by recycling the part-stream of the gas. The following process steps are carried out by removing the gas from the system at an outlet point (4) in a preliminary stage comprising a compressor (1), a cooler (2) and a separator (3) for preliminary separation of part of the solvent by condensation. The gas stream containing residual solvent is then fed to a final stage which comprises a pressure swing adsorption unit (6, 7) and is adsorbed by an adsorbent for separating off the residual solvent, a relatively large part of the purified gas then being removed from the system at an outlet point (9) (Fig. 1). <IMAGE>

Title: Current pick-off
Inventor: VALTONEN RAINER I T
IPC: H01R25/14
Filed: 1989-01-30
Abstract: The invention relates to a current pick-off for an electrical busbar.

Title: Arrangement at a cross joint of concrete paving (floor) slabs
Inventor: FOERSTER EDWIN DIPL ING
IPC: E01C11/10
Filed: 1989-05-12
Abstract: An arrangement at a cross joint of concrete paving slabs has a strip-like joint plate which is arranged in the cross joint and whose height corresponds approximately to the height of the cross joint and also a sealing joint compound which is introduced subsequently from above into a joint of lower depth which is produced by material removal at the joint plate. In order to obviate the need at the installation site for finishing work and the use of machines for the formation of the sealing joint, provision is made for the joint plate to be formed from a hollow profile of plastic and to have, at least in its region located at the top in the installed state, a chamber which runs in the direction of the longitudinal extent and is formed by the side walls which define the joint width, a top wall approximately flush with the surface of the paving slabs, and a bottom arranged at a distance below the top wall, both side walls exhibiting predetermined breaking points extending linearly over the length of the hollow profile. By tearing open the predetermined breaking points, the top wall can be removed together with the adjoining side-wall portions, so that a sealing joint which is open only at the top results.
