Title: Process for preparing a modified aqueous chlorite solution, the solution prepared accordingly, and use thereof
Inventor: BERGER PETER
IPC: A01N59/00
Filed: 1984-02-02
Abstract: A process is described for preparing a stabilised, modified aqueous chlorite solution having a proportion of a peroxy compound, a weakly acidic aqueous solution of a peroxy compound essentially stable therein being introduced as an initial charge and an aqueous solution of a chlorite being metered into said solution for as long as is required to exceed the pH of 7 with the formation of a greenish solution. Possible peroxy compounds are, in particular, persulphates, percarbonates and perborates of alkali metals or alkaline earth metals, as well as hydrogen peroxide. The chlorite solutions produced according to the abovementioned process have long-term stability and high oxidative activity, especially when used as a biocide. The biocidal activity can be used to particular advantage in purifying water and in the external treatment of skin diseases.

Title: Biological degradation of refuse, sewage sludge supported by exhaust gases from power stations and steelworks
Inventor: FASSINGER EUGEN
IPC: C02F11/00
Filed: 1984-02-08
Abstract: Refuse freed from metals is finely ground and forced by a screw conveyor into a steel pipe perforated by many small holes, into which pipe hot steam is forced from outside. The refuse material is then transported with thickened sewage sludge, liquid manure and the like into a large vessel into which exhaust gases from the power station are blown from the bottom and the microbes then convert the substances at 80 DEG  to 100 DEG C. The gases forming during this are trapped at the top and the converted substances are discharged. A screw conveyor transports the heavy fractions to the outside where they are layered in large pipes in the shaking process.

Title: Method and device for the storage of liquid manure
Inventor: BLUM ALBERT
IPC: A01C3/02
Filed: 1984-02-20
Abstract: A method and device for the storage of liquid manure or suchlike fluids which are laden with particulate impurities and consist of organic fermenting substances are indicated, and in these an improvement of the pumping capacity and a reduction of the annoyance caused by odours become possible. For this purpose, the liquid manure collected in a sump is sucked up in its surface region by a vertically adjustable submerged pump which is provided with a comminuting attachment. The fluid is subsequently aerated and then returned to the sump in a free jet. There thus takes place an enrichment of the fluid with air and a continuous swirling which prevent particles from floating and a surface layer from forming.

Title: Hopper for bulk materials, in particular cement raw meal
Inventor: POU TEODORE
IPC: B65D88/72
Filed: 1984-11-08
Abstract: The hopper for bulk materials, in particular cement raw meal, is equipped with an accessible conical hood (1) which, together with the preferably cylindrical outer wall (2), forms an annular hopper bottom (3) from which the bulk materials stored are extracted, for example by means of air-conveying channels. The conical hood is not made of steel-reinforced concrete, but of segments of steel sheet which are supported by an appropriate scaffold or framework (5, 6) and have a concave shape so that they are not subjected to compression but largely to tension. This type of loading can be absorbed by steel sheet constructions. By replacing the steel-reinforced concrete with a steel sheet construction, the hopper can be produced in a far more cost-effective manner without disadvantages in terms of functioning and loadability having to be tolerated. <IMAGE>

Patent DE-3506173-A1 (DE)
Title: Process for producing adhesive surfaces for high stressing of the adhesive joint
Inventor: LITWIN HANS DIPL ING
IPC: B28B11/04
Filed: 1985-02-22
Abstract: The shape and strength of microfibres obtained by a machining process, preferably of steel (irregular shape with sharply serrated and highly lacerated boundary lines of the surfaces), are used as bonding layer and simultaneously as reinforcement of the adhesive joint between two mouldings A and B, in such a manner that these microfibres are applied to the reverse side of the moulding A by scattering or spraying on, if appropriate with additional light pressure, so as to cover the surface, the matrix having to be of such a consistency that a part of the individual fibres is anchored like a dowel in the surface. The other part projects out and, on joining together, anchors itself in the matrix, of corresponding consistency, of the moulding B. This process is used especially in the production of permanent formwork of fibrated cement, where the fresh cement matrix joins to the set cement matrix. A still higher bond strength can be obtained if, in addition to the fibrous surface reinforcement, spotwise reinforcement takes place by the wire inserts or dowels. See P 3012792.5 of 02.04.1980 for the reinforcing effect of this type of fibre.

Title: Metal hand-held shower
Inventor: GRASSE KLAUS-PETER DIPL ING
IPC: B05B15/06
Filed: 1985-03-05
Abstract: A metal hand-held shower (10) having a water-guiding channel and a grip (11) enclosing the latter at least over part of its length, a flexible-tube connection nipple (12) and a water outlet (14) is adroitly configured such that, while dispersing with a separate grip consisting of an insulating material, unpleasant overheating or also excessive cooling of the grip (11) cannot occur. This is achieved in that the grip (11) also consists of metal, in that the water-guiding channel comprises a tube (16), in particular a copper tube, which is known per se in the case of outlet fittings, and in that this tube (16) is fastened, such that it is sealed with respect to the grip cavity (21), on the flexible-tube connection nipple (12) with one end (16a) and in the region of a wall opening (15a) of the water outlet (14) with its other end (16b). The grip cavity (21), forming an outwardly closed space, completely encloses the tube casing (16c) at a distance. Although the hand-held shower consists entirely of metal, the grip essentially maintains room temperature because the grip cavity (21), enclosing the water-guiding tube (16), is outwardly closed and forms a heat-insulating air cushion. <IMAGE>

Patent DE-3521738-A1 (DE)
Title: Pressure and guide device and distance bolt
Inventor: KEGENBEIN HELGE DR
IPC: E02D5/52
Filed: 1985-06-18
Abstract: In accordance with the abovementioned Offenlegungsschrift, pipes with tapered internal and external stepped surfaces in which grooves are made are connected to one another by ramming and are placed in the ground. During extraction of the line, the pipe sections are separated by screwing bolts or a pressure device into tapped holes in the outer pipe of the connection, in the course of which the bolt presses the axially slit segments provided with grooves to the inside and disengages the grooves so that the connection can be released. The subject-matter of the application is a pressure and guide device (Fig. 1) which consists of a ring with the number of hydraulic pistons corresponding to the number of segments. The hinged device centring vertically and peripherally is put onto the pipe end provided with the internal stepped surface. The segments of the inner pipe end are pressed to the inside by the admission of fluid to the pistons, and catching of the pipe section before reaching the shoulder position is avoided. Dismantling is effected in an analogous manner, in the course of which a considerable piston pressure is achieved by absorption of the forces by the ring and thus the engaged grooves are reliably released. <IMAGE>
Patent DE-3527040-A1 (DE)
Title: Thermographic print head
Inventor: SPRINGER JOHANN DR RER NAT
IPC: B41J2/335
Filed: 1985-07-27
Abstract: Thermographic print heads have a layer giving protection against abrasion which is conventionally 10 to 15  mu m thick. According to the invention, the protective layer (6) consists of a rigid material with a much longer service life than the layers hitherto conventional. As a result, the layer thickness can be reduced to a fraction of the previous thickness. The protective layers are in many cases sensitive to temperatures above 400 DEG C. With the pulsed driving of the heating elements (9) over a predetermined duration which has hitherto been conventional, unnecessarily high peak temperatures arise. The pulsed driving is thus replaced by driving with a sequence of pulses, as a result of which the peak temperatures that have arisen hitherto are avoided. <IMAGE>

Title: Method for producing a trip signal as a function of the magnitude and duration of an overcurrent
Inventor: STROZYK PETER ING GRAD
IPC: H02H1/04
Filed: 1986-09-11
Abstract: The invention relates to a method for producing a trip signal as a function of the behaviour of an overcurrent, in the case of which method digital values which are derived from the overcurrent are added up on a weighted basis, and the trip signal is formed at a predetermined total value. In this case, the digital values which are in each case produced last are stored, the stored values are compared with one another and are used to derive a criterion possibly for reversing the summation. In the case of such a method, in order to produce reporting signals which unambiguously provide information on the ongoing formation of a trip signal, once a predetermined threshold value has been exceeded for a predetermined time interval, monitoring is carried out to determine whether the respectively stored maximum value is above the response threshold. If this is the case, then the reporting signals (alarm signals) are produced, and the predetermined threshold is reduced to a lower level. <IMAGE>
