Patent DE-3719099-A1 (DE)
Title: Solar energy facility
Inventor: WENZEL JOACHIM
IPC: F24S10/40
Filed: 1987-06-06
Abstract: The invention concerns a solar energy facility with plane absorbers and/or solar cells in a collector field at whose edges, at least partially, one or more plane reflecting surfaces are arranged at an angle to the absorbers and/or solar cells. The solar radiation impinging on the reflecting surfaces falls at least in part on the absorbers and/or solar cells. The reflecting surfaces and the absorber surfaces and/or solar cells are positioned rigidly on the roof of a building or on support elements, while the reflecting surfaces are fastened in a plane running north and/or south and slanted with respect to the absorber plane. The reflecting surfaces extend sidewards beyond the absorber surfaces without shadowing the absorbers, in accordance with Patent 3600881. In order here to be able to enlarge the reflecting surfaces substantially, so that correspondingly high temperatures can be achieved with little effort relatively quickly, for example, the invention proposes that the reflecting surfaces and their associated support elements in one of the planes running north or south be divided into two or more plane reflecting surfaces, whose inclinations from the horizontal increase with increasing distance from the absorbers. If in this case the distance between the rows of collectors or solar-cell modules, in which the reflecting surfaces with their associated support elements are arranged, a = 200...

Patent DE-3723341-A1 (DE)
Inventor: KRECKE EDMOND D
IPC: E04B2/86
Filed: 1987-07-15
Abstract: In one of the methods, connecting elements made by using concrete are produced by first pouring a fluid mortar, on the inside of a wall (1), into openings (5) of a template (2), with the addition of an adhesion promoter. A bell- or disc-shaped casting mould, which is filled with earth-moist concrete and is centred by the openings, is then placed upon this fluid mortar. The form elements thus produced can be stacked for hardening, with the interposition of thin plates, and subsequently joined to form form-element halves, for example by adhesive bonding. Modified methods produce the form elements by using dumbbell-shaped connecting elements made with the aid of axially separated mould halves. Form elements produced according to the method permit numerous modifications. <IMAGE>

Title: Process for recovering a dissolved ionic substance
Inventor: SRIDHAR SRINIVASAN DR
IPC: C01B17/90
Filed: 1988-04-13
Abstract: Ionic substances can be separated off from possibly contaminated aqueous solutions by diffusion dialysis or electrodialysis; the pure solution obtained has a lower concentration than the solution introduced. A large membrane surface area is required for the diffusion dialysis. By means of the novel process, a pure solution of the ionic substance is obtained, the concentration of which is exactly as high as, or higher than, concentrations of the contaminated solution introduced. Moreover, only a moderately high membrane surface area is required for the diffusion dialysis. In the novel process, with respect to the donor streams, a diffusion dialysis stage and an electrodialysis stage are connected in parallel; a further electrodialysis stage is provided downstream of both stages. With respect to the acceptor streams, both electrodialysis stages are connected one after the other; the diffusion dialysis stage is connected in parallel to an electrodialysis stage. Recovery of concentrated pure solutions of organic and inorganic acids and liquors from solutions contaminated by nonionic substances, e.g. sulphuric acid or maleic acid from filtered fermenter broth. <IMAGE>

Patent DE-3815986-A1 (DE)
Title: Magnetic separator
Inventor: KUHNHENN MANFRED
IPC: B03C1/03
Filed: 1988-05-10
Abstract: In the mounting of a magnetic separator, in particular a superconductor concentrated field magnetic separator, it cannot be avoided that, due to non-uniform loading or temperature influences, transverse forces are transmitted onto the bearings, which transverse forces lead to edge loading in the bearings and thus destroy the bearings after a relatively short period of operation. This is all the more the case as essential bearing parts have hitherto been constructed from electrically non-conductive, relatively soft and, furthermore, temperature-sensitive material. The service life of bearings constructed in such a manner was thus relatively short. According to the invention, however, an eddy-current-free mounting of a magnetic separator, having a very long service life is achieved in a simple manner in that the sliding bearings (1, 2) comprise a bearing housing (5, 6, 7) constructed from a plurality of parts, a bearing ring (8, 9) having a spherically curved outer surface (10, 11), a bearing shell (12, 13) and a bearing sleeve (14, 15), the bearing housing (5, 6, 7), the bearing ring (8, 9) and the bearing shell (12, 13) being constructed from electrically non-conductive material. <IMAGE>

Title: Method for testing injection valves and apparatus for carrying out the method
Inventor: MANZ PETER DIPL ING
IPC: B05B12/08
Filed: 1988-05-19
Abstract: A method for testing injection valves is described in which a laser beam (5) penetrating the exit stream (3) of an injection valve (1) underneath its exit opening (9) is captured by a receiver (6), from which the signal is used in an evaluation unit (7) connected downstream to make a statement about the production quality of the injection valve (1). In order to be able to make a most rapid and sufficiently accurate statement about the static flow of injection valves, this is intended to be detected by means of detecting the scattered light signal from the laser beam (5) captured by the receiver (6). This scattered light signal is then intended to be compared with previously determined desired-value scattered light signals of exactly dimensioned injection valves lying within the predetermined production tolerance band. Furthermore, an apparatus for carrying out this method is specified. <IMAGE>

Title: Analysis device for the agitation of a reaction solution and reaction container for use in the device
Inventor: HAMASAKI FUMITOSHI
IPC: B01F13/08
Filed: 1988-11-11
Abstract: A multiplicity of reaction containers, each of which is provided with an agitating sphere which is made of a magnetic material, are arranged on a reaction disc in a circle, in order to be supplied with a reagent and a sample. The reaction disc is driven to-and-fro with a small amplitude for a predetermined time, each time that a new reaction container is supplied with the reagent, in order to cause the reaction containers to be displaced into vibration in a circular arc shape. As a result of the vibration of the reaction containers, the agitating spheres move violently in the respective reaction containers and agitate the reaction solutions in the reaction containers. A photometric apparatus is so arranged that it throws light onto the reaction container and thereby enables a fluorescence or absorption photometric measurement. In the reaction container which is brought into the position of the photometric measurement, the agitating sphere is drawn to the wall of the reaction container, in order that it is removed from the path of the light in the photometric apparatus.

Title: Variable-displacement pump with a pump control valve
Inventor: NIKOLAUS HEINRICH PROF DR ING
IPC: F04B49/08
Filed: 1988-12-30
Abstract: In a hydraulic system with a variable-displacement pump, a limit signal is produced if the load-carrying consumer continues to signal a delivery-flow demand at maximum delivery-flow rate of the pump. The limit signal is produced as a function of position at the servo piston of the pump or at the pump control valve, which passes into an end position. The limit signal can be produced hydraulically or electrically. If the limit signal occurs, measures for changing the flow through the consumers are initiated. In a corresponding manner, a limit signal signalling excess supply can also be produced if no pump output is demanded.
