Title: Arrangement for determining dynamic fracture toughness
Inventor: CLOS RAINER DR SC NAT
IPC: G01N3/02
Filed: 1987-05-29
Abstract: The invention concerns an arrangement for determining the dynamic fracture toughness of metallic materials at rates of change of the stress intensity factor K in the range from 10<6> to 10<7> MPa m<1/2>s<-1>, which must be anticipated in shock loads or in accidents, such as in neutron-embrittled reactor pressure vessels of nuclear power stations. The shock load is applied by means of a waveguide in effective contact with the sample. The aim is to reduce the amount of sample material and shielding measures, and the manufacturing costs of the samples. For this purpose, an arrangement is to be developed that allows the use of very small samples. According to the invention, the sample (3) is positioned between the faces of two axially aligned waveguides. The longitudinal axis of the waveguides intersects the longitudinal axis of the sample (3) and runs symmetrically to the plane of the fracture. The waveguide located on the fractured side of the sample (3) is effectively linked to the sample (3) by way of a bridge-shaped coupler, while the second waveguide is effectively linked to the sample (3) by way of a second coupler touching the sample in the fracture plane roughly along a line. <IMAGE>

Title: Sound-absorbing structural element and process for the production thereof
Inventor: ROLLNIK HUBERT DIPL ING
IPC: E04B1/84
Filed: 1987-08-21
Abstract: Sound-absorbing structural elements are provided, on their front side (12), with a multiplicity of protrusions (13) and depressions (14) following one after the other. In the region of the depressions (14), a relatively low degree of sound insulation is obtained because the structural element (noise-insulation element 10) is of a relatively low thickness at this point. The structural element (noise-insulation element 10) according to the invention is to remedy this. In order to improve the sound insulation, absorber bodies (18) are embedded in the structural element (noise-insulation element 10) according to the invention, to be precise preferably in the regions of the depressions (14). The structural elements configured according to the invention are particularly suitable as noise-insulation elements (10), but also as wall elements, ceiling elements, floor coverings and the like. <IMAGE>
Patent DE-3730685-A1 (DE)
Title: Pressure lubrication system for rotary-vane vacuum pumps
Inventor: ENGMANN HUBERT DIPL ING
IPC: F04C29/02
Filed: 1987-09-12
Abstract: The invention relates to a pressure lubrication system for rotary-vane vacuum pumps. It provides for the force-feed duct to be composed of sections in the end shields and end journals and a section in the rotor's slide gap end. The sections in the end journals are formed so that when turned they act as stop-cocks between the sections in the end shields and the slide gap. Their apertures on the periphery of the journals are offset so that when the slide gap is enlarged, the section in the end shield, which also holds the oil pump, is connected to the slide gap, and when the slide gap is reduced, the section in the other end shield is connected to the slide gap. The invention results in better lubrication of the slides, a better seal of the rotor slot, more cooling when much compression work is being done, and a good self-cleansing effect in the rotor slot in rugged industrial use.
Patent DE-3731916-A1 (DE)
Title: Novel boiler for generating steam, warm water, or hot water
Inventor: HAFERKAMP WOLFGANG
IPC: F24H1/28
Filed: 1987-09-23
Abstract: The invention concerns the use of flue-gas heat exchangers built directly into the boiler water space, and arranged in counterflow to the natural circulation of the boiler water, which heat exchangers are constructed either as annular-gap heat exchangers with fins, or as tubular heat exchangers with smooth or corrugated tubes. An additional such heat exchanger can be connected downstream as a controlled waste-gas heat exchanger. The new boiler design is a combination of large-water-space boiler and high-speed steam generator, and combines the advantages of these types of boiler, that have been employed mainly in the lower power range to date, while largely avoiding their respective disadvantages. This allows more economical and less fault-prone boiler operation in the long term, especially in plants with lower steam or warm-water requirements, with consumption at intervals and lengthy standstill periods, also when using the residual heat of the flue gases. <IMAGE>

Patent DE-3816226-A1 (DE)
Inventor: JUNG ERNST DR
IPC: C02F1/46
Filed: 1988-05-11
Abstract: A device for the separation of emulsions, in which metal ions for binding the emulsified substances are introduced into the emulsion by electrolysis, is equipped with a tubular sacrificial anode (100), a cathode (101) which faces an end surface of the sacrificial anode, forming a gap (103) through which the emulsion enters, packing (110) arranged on the cathode, on which the end surface of the sacrificial anode rests to define the height of the gap, and a drive mechanism (105), which produces a rotary movement between the cathode and the sacrificial anode about their axis (A). The improvement over the prior art consists in the fact that the drive mechanism (105) is coupled to the tubular sacrificial anode (100) in such a manner that in defined limits a free radial movement is possible between sacrificial anode and cathode, which is superimposed on the rotary movement between sacrificial anode and cathode. <IMAGE>

Title: Process for the production of photographs from exposed and developed, masked, colour-negative films on colour-negative papers
Inventor: DAENZER PETER
IPC: G03B27/73
Filed: 1988-12-02
Abstract: In the production, i.e. enlargement, reduction or copying, of photographs from exposed and developed, masked colour-negative films on colour-negative papers or films, the masked colour-negative film is in each case introduced into the ray path between a time-controlled light source and the colour-negative paper or film, so that ultimately positive-coloured reflected-colour photographs are obtained. In order to provide a process, which enables natural colour reproduction in an extremely simple manner and significantly simplifies the working operations which were hitherto complicated, it is proposed that the masked colour-negative film be associated in the ray path with an unexposed, developed part of the same masked colour-negative film, so that the masks lift one another, and that the exposure is selected so that the colour-negative paper or the colour-negative film is rendered neutral.
