Patent DE-3144357-A1 (DE)
Title: Process and equipment for continuous, substantially uniform charging of drying installations with solids
Inventor: HINTERKEUSER JAKOB
IPC: F26B25/00
Filed: 1981-11-07
Abstract: When charging drying installations, in particular drum dryers, with moist and/or tacky solids such as clay or marl, quantitative fluctuations occur due to irregular extensive caking, and this leads to temporary overloading of the drying installation. Wide fluctuations in the charging of the drying installation with moist and/or tacky solids adversely affect not only the operation but also the drying effect of the drying installation. According to the invention, these disadvantages are avoided, when the amount of solids is excessive, by determining by weight the amount of the excess solids, branching it off upstream of the drying installation and returning it to charging. <IMAGE>

Title: Sun protection device having a plurality of parallel lamellae
Inventor: SCHNEIDER RUDOLF
IPC: E06B9/302
Filed: 1981-11-26
Abstract: A sun protection device has a plurality of parallel lamellae (1, 2, 3, 4, 5), which are connected to one another via at least two scissor arrangements (13), each scissor arrangement being formed from a plurality of pairs of levers (14, 15) each pivoted on one another and being guided on the building at a plurality of points (17) disposed parallel to one another. A drive device (23 to 25) is provided for adjusting the sun protection device or the lamellae. To make it possible for the scissors-type construction to be used even with a relatively large length of lamellae and to ensure an orderly guiding of the individual lamellae (1 to 5) for the particular use, the scissor arrangements (13) are distributed between the ends of the lamellae (1 to 5). The lamellae each have, in alignment, a perforation (27) for the passage of two levers (14, 15) each per scissor arrangement.

Patent DE-3149141-A1 (DE)
Title: Fade-in device for spinal function photographs
Inventor: FRANZ JOERG
IPC: G03B42/02
Filed: 1981-12-11
Abstract: The invention relates to a "fade-in device for spinal function photographs". In order to take functional photographs of the lumbar spine with as much anteflexion and retroflexion as possible, the patient must execute a maximum possible movement of anteflexion and retroflexion in the lateral beam path without substantially moving position (see Fig. 1 + 2). For this purpose, it is necessary in an X-ray machine for the multileaf diaphragm and the cassette to be rotatable about the central beam. This is not the case with most machines. By adapting the invention to every possible X-ray machine, rotatability can be achieved without great cost. As a result, every orthopaedist can apply this photographing technique, since it is possible by rotating the cassette holder and the radiation beam to adapt both to the mobility of the patient. <IMAGE>

IPC: B65D5/42
Filed: 1981-12-15
Abstract: A container comprising a web or blank of material of limited flexibility with wall portions in which at least one edge is separated from a bent-over edge strip portion by a bend line, is provided with a maximum degree of stability so as to avoid any outward bulging and to resist the resilient forces tending to cause a return to an initial position. For that purpose, the bend line is interrupted by at least one geometrical surface portion serving as a stabilizing member which projects both into the edge strip portion and also into the wall portions, and which is separated from both by desired or predetermined bend lines. The blank can be made of cardboard with a coating of aluminum film or foil, for lining the interior of the container and the bend line is interrupted by at least one geometrical surface portion which projects into both portions of the blank, which are adjacent to the bend line, that is to say, the edge strip portion and the wall portion, and the stabilizing member is separated from the edge strip portion and the wall by bend lines which are at least partly cut. In both cases, at least the bend line is preferably produced by stamping or embossing, or by perforations.

Title: Method for producing coated optical surfaces
Inventor: FISCHER BERND
IPC: G02B1/118
Filed: 1982-06-11
Abstract: The invention specifies a new method for producing optical surfaces coated according to the principle of the refractive index that increases with the material depth, e.g. of light-transmitted elements such as optical elements for high-power lasers with the use of an etching process. The essential novelty of the method consists in that the surface to be coated is bombarded at right angles in a suitable apparatus with ions which generate latent nuclear tracks on the material. In this case, the mean separation of ions from one another is approximately 0.01 to 0.1  mu m, the penetration depth is approximately 1 x  lambda  to 5 x  lambda  ( lambda  = wavelength of the light employed). After irradiation, the bombarded surface is etched to the extent that the largest opening of the etching cone of an individual nuclear track does not exceed 0.1  mu m. The particular advantage of the novel method consists in that it is now also possible to coat 1-component lenses in a simple way.

Title: Method of producing a differential-pressure measuring capsule
Inventor: BISKUP JUERGEN
IPC: G01L7/08
Filed: 1982-07-09
Abstract: The differential-pressure measuring capsule consists of two backing discs between which a measuring diaphragm is held. A tensile stress acts on the measuring diaphragm in the radial direction. In order to produce this tensile stress, solder is applied between each backing disc and the measuring diaphragm in the peripheral area. During the heating, clamping devices prevent the backing discs from expanding radially. After the solder has fused with the backing discs and the measuring diaphragm, the clamping devices are removed only after the cooling-down to below the solidification point of the solder. Differential-pressure measuring capsules made of both metal and ceramic or glass can be produced by this method.

Patent DE-3248473-A1 (DE)
Inventor: ARTZ GERD
IPC: B22D11/06
Filed: 1982-12-29
Abstract: Beim Vergießen flüssiger Metalle stellt sich in modernen Verfahren die Aufgabe, den Spalt zwischen ruhenden und bewegten Systemen abzudichten, damit keine Schmelze über den Spalt ausfließt. Bei Schmelzen mit hohen Temperaturen und der Neigung, Legierungen zu bilden, fehlt es an Materialien, mit deren Hilfe die Schlitze dauerhaft abgedichtet werden können. Durch den kombinierten Einsatz pneumatischer und elektromagnetischer Kräfte läßt sich ein Spalt besonders vorteilhaft abdichten, wenn die elektromagnetischen Kräfte dazu benutzt werden, den Flüssigkeitsdruck zu homogenisieren, d.h. den Oberflächendruck auf einen konstanten Wert abzusenken. Der abgesenkte Druck kann pneumatisch kompensiert werden. Nach dem erfindungsgemäßen Verfahren wird ein den minimalen Flüssigkeitsdruck am Spaltquerschnitt nicht überschreitender Teil des Flüssigkeitsdruckes pneumatisch und der Rest des Flüssigkeitsdruckes durch elektromagnetische Kräfte kompensiert. Die elektromagnetischen Kräfte resultieren aus der Wechselwirkung einer magnetischen Induktion mit Strömen in der Flüssigkeit.

Abstract: To design the flushing valve with a flushing-stream regulating means which automatically compensates for fluctuations in water pressure and at the same time with favourable noise behaviour, a cylindrical insert consisting of upper part and lower part is arranged in the tubular housing space adjoining the flushing valve. The upper part contains a plurality of axial through-flow bores which are distributed in the form of a ring over the edge zone region of the upper part and adjoined by a disc-shaped retaining space between upper part and lower part. Below the mouth of the through-flow bores, a plurality of restricting bores, arranged only on a single hole circle, lead from the retaining space axially through the lower part to the outlet of the flushing-valve housing. A restricting ring made of a rubber-elastically deformable material is placed on the end face of the lower part, which end face faces the retaining space and is domed in the form of a spherical cap inside the inlet of the restricting bores, outside the inlet of the restricting bores. The restricting ring protrudes, with its inner peripheral edge, radially from outside slightly into the inlet cross-section of the restricting bores and causes, in the case of a water pressure increase and radial compression of the restricting ring occurring as a result, an increasing constriction of the inlet cross-section of the restricting bores and hence a substantially constant discharging flushing stream at different water-pipe pressures upstream of the flushing valve in the case of ... on the flow of water in the ...
