Patent DE-3537351-A1 (DE)
Title: Method and device for removing a ceramic core from a cast element
Inventor: HUININK OSWALD
IPC: B22D29/00
Filed: 1985-10-19
Abstract: In high-quality cast elements, such as the blades of aviation turbines with internal cooling, the core which consists of ceramic is frequently very complicated in design. This makes removing the core after casting the blades very difficult. The known method for removing the cores in an autoclave at pressures of 10<6> bar is costly in terms of apparatus. The expenditure can be substantially reduced by the liquid which dissolves the ceramic being sprayed with a rotating pump (3) with a jet (5) which is directed onto the ceramic core of the cast element (6). The liquid (2) which dissolves the ceramic is collected in a container and fed back to the pump (3) through a lower discharge pipe (1a). <IMAGE>

Title: Apparatus for arranging and combining vessels and the like
Inventor: SPIESS BERND
IPC: B65G47/68
Filed: 1985-12-11
Abstract: An apparatus for arranging and combining vessels and the like comprises a wide feeding conveyor having a plurality of conveyor belts which extend alongside one another and move at different speeds, and having an individual conveyor connected to the said belts. These conveyors are used to bring bottles or the like, with a high throughput, from a wide conveyor into a single track. However, if bottles having a special bottom standing surface are to be supplied one behind the other in an aligned fashion from such a wide feeding conveyor onto the single track, such an apparatus will fail, because the vessels do not line up one behind the other to form an uninterrupted row, but are instead prone to the immediate formation of arches and the like. The object has therefore been set of combining bottles which preferably cause problems, such as bottles which are oval, rectangular or similarly shaped in the region of their bottom standing surface in an appropriate fashion at a high speed. To this end, it is proposed that vessels having a positively aligned bottom surface be lifted up essentially over their entire surfaces from the plane in which they are already being conveyed and be conveyed away to the single track along a rail guide and that vessels having a negatively aligned bottom surface be at least partially supported by a second conveying plane which is situated alongside the first plane and moves at a higher speed, and be made to rotate transversely to their vertical axis and/or be moved ahead.

Filed: 1986-10-03
Abstract: 1. Process for disposal of caustic solution from cleaning machines, in particular bottle cleaning machines (11, 12, 13, 14), by draining the caustic solution intermittently into associated setting tanks (21, 22, 23, 24), settling of the suspended solids taking place after several hours so that about 90% of the sediment is precipitated from the caustic solution after which the caustic solution cleaned to a very large extent is returned to the cleaning machines, while the highly alkaline sludge left as a residue is further treated, characterized in that the sludge and part of the caustic solution remaining in the settling tank (21, 22, 23, 24) are drawn off and passed to a sludge thickening system (30) in which the sludge is further concentrated, that the clarified clean caustic solution accumulating in the upper part of the thickening tower (31) is continuously drawn off and after intermediate storage in a clean caustic solution tank (32) led to a settling tank (21, 22, 23, 24) or a manipulation tank (27), that the sludge accumulating in the sludge thickening tower (31) is passed through a downstream flocculant station (39) in which a flocculant is added to the sludge, and that the sludge is subsequently dewatered in a screening container (37, 40).
Patent DE-3634323-A1 (DE)
Title: Method and apparatus for centrifugal separation of a flotation suspension mixture
Inventor: LESCHONSKI KURT PROF DR ING
IPC: B03D1/14
Filed: 1986-10-08
Abstract: The centrifugal separation of a flotation mixture containing fine particles, for example of a biological sludge, into a disperse first solid component containing bubbles and a bubble-free, disperse second solid component is performed, in order to increase the sorting effect and the mass flow rate compared with such a separation in hydrocyclones, in such a way that the suspension mixture is delivered continuously and carefully onto the centre of a rotating bowl-shaped surface (centrifuge rotor 1) in such a manner as to prevent the detachment of bubbles from the water-repellant particles, and, after preliminary acceleration, is dispersed into a thin suspension layer (4) expanding in the flow direction. A transverse flow separation in the centrifugal force field thus takes place under the effect of buoyancy and acceleration forces. Two layers, each having an enriched component, are formed, are separated from one another at the edge of the rotor (1), which is open at one side, by means of a coaxial circular cutting edge (6) and are removed individually. In the feed channel for the suspension there is provided, for the preliminary acceleration of the suspension mixture (4) in the direction of rotation, a swell apparatus (11) and, upstream of the mouth of the feed channel at the bottom (2) of the rotor (2), a blade ring (13). <IMAGE>

Patent DE-3723584-A1 (DE)
Title: Special circuit for the possible exchange of the output potentials
Inventor: MERKLE PAUL
IPC: G06F7/48
Filed: 1987-07-16
Abstract: The potential exchange circuit according to the subject of the invention has the effect that the A potential is displaced to the left if the B potential is less than the A potential. This case occurs if the inputs A4 and B2 are triggered with high potential. In this case, the outputs C2 and D4 have high potential, and thus the intended purpose is achieved. In the reverse case (the inputs A2 and B4 are triggered), the outputs C2 and D4 also have high potential, because no exchange occurs in this case. <IMAGE>
Patent DE-3724253-A1 (DE)
Title: Heat-insulating composite profile
Inventor: QUICKER HERBERT
IPC: B29C65/60
Filed: 1987-07-22
Abstract: The invention relates to a heat-insulating composite profile, a process for the production thereof, and a punching/bending tool used in the production process. The composite profile (1) is made up of two spaced-apart metal profile bars (4, 4') which are parallel in the profile longitudinal direction (2) and have in each case at least one groove (6) running continuously in the profile longitudinal direction (2), and at least one cross-sectionally essentially U-shaped insulating profile (5) which connects the profile bars (4, 4'). The U-base web (10) of said insulating profile spans the separating joint (3) between the profile bars (4, 4'). Each of the U-leg webs (12) engages into the groove openings (7) of the profile bars (4, 4') and is embedded in a positively locking manner in the grooves (6), by means of the application of ultrasound. The grooves (6) of the profile bars (4) are undercut beneath the groove openings (7) and thus form groove webs (16) which flank the groove openings (7). In order to form a plurality of barb-like protrusions (22) effective in the profile longitudinal direction (2), the groove webs (16) are bent off in the direction of the groove base (21), such that they project into the undercut regions (23) of the profile-bar grooves (6). The U-leg webs (12) of the insulating profile (5) are also embedded in a positively locking manner into the undercut regions (23) of the profile-bar grooves (6) by means of the application of ultrasound, such that they engage behind the groove webs (16) with their barb-like protrusions (22). <IMAGE>

Title: Method for producing phase-shifted alternating currents at the same frequency and/or at a multiple of the frequency, especially for telecommunications exchangers
Inventor: DIRR JOSEF DIPL ING
IPC: H04L27/20
Filed: 1987-10-10
Abstract: Phase-shifted alternating currents at the same frequency are required throughout telecommunications technology, for example in the case of quadrature-amplitude modulation. Until now, very complex circuits have been required for this purpose. In the case of the present invention, the phase shift is produced by means of a counting element, in that the desired phase angle is produced by the ratio of the overall output count of the counting element to the output count of the desired phase shift. In this case, there are electronic switching means in the outputs, which produce unipolar or bipolar square-waveform pulses by means of the coded outputs. Sinusoidal alternating currents are then filtered out of the square-waveform pulses by means of filters, said square-waveform pulses actually being phase-shifted.
Patent DE-3734755-A1 (DE)
Inventor: GEKE JUERGEN DR
IPC: C08F220/12
Filed: 1987-10-14
Abstract: Conventional concentrated solvent-free aqueous polyacrylate dispersions or polyacrylate emulsions generally have a highly acidic pH of from 2 to 3.5, which means that they have highly corrosive properties on the metal objects to be protected. By contrast, the novel polyacrylate dispersions and the coating compositions containing them have only a slightly acidic pH of from 4 to 6. The polyacrylate dispersions having the above slightly acidic pH are obtained by neutralising from 5 to 50 mol % of the carboxyl-carrying comonomers by means of a base before the copolymerisation with hydrophobic comonomers. The resultant polyacrylate dispersions dry on objects to give clear water-resistant films which can easily be removed using alkaline agents. Their pH of from 4 to 6 means that they are significantly less corrosive towards the objects to be protected. The aqueous polyacrylate dispersions or polyacrylate emulsions are used as coating compositions for temporary surface-protection of metallic and/or painted surfaces, in particular automobile bodies, against climatic and/or mechanical influences.

Title: Device for the external fixation and repositioning of bone fragments
Inventor: WASSERSTEIN ISIDOR PROF DR MED
IPC: A61B17/62
Filed: 1988-01-30
Abstract: The invention relates to a device for the dynamic external fixation and repositioning of bone fragments and joint parts using at least two rings suitable for tensioning Kirschner wires, the rings being connected and adjustable relative to one another. Devices of a conventional type are suitable for small defects but are insufficient for treatment of defects exceeding a length of three or more centimetres because the soft tissue parts which are anyway affected considerably would then be stressed additionally in a harmful way by tension or pressure. The invention therefore provides for the additional attachment of further Kirschner wires which are fastened on only one side to one of the rings via mountings, whereas the other end is provided with a ball plate joint. This design permits the wires to assume an angle of inclination which does not represent any additional load on the skin and soft tissue parts on compression displacements (Fig. 1). <IMAGE>
