Patent DE-3805413-A1 (DE)
Title: Heat insulation for a rafter roof
Inventor: BECK ERHARD
IPC: E04D12/00
Filed: 1988-02-22
Abstract: The invention is intended to ensure good cost-effective heat insulation in the roof structure. A loose fill of heat-insulating material between the rafters is intended to prevent holes and slits through which the heat can escape. Trussing sheets which are open to diffusion are fitted on the rafters, transversely thereto. On the left-hand side and right-hand side in the longitudinal direction, said trussing sheets exhibit a bent-over portion, with the result that, by pushing the bent-over portions one into the other, they can be fitted together to form a continuous surface. Nailing boards or battens onto the rafters via the trussing sheets holds said sheets and tensions them between the rafters, said nailing-on resulting in ventilation (through-ventilation) and, in the event of moisture occurring, the loose fill of heat insulation can thus be rapidly dried out again.

Filed: 1988-05-30
Abstract: In thin-film magnetic heads, the magnetic guiding body is of sandwich construction and comprises a magnetic coil (9, 9') arranged between magnetic core halves (2, 2' and 4, 4'). The guiding body is of constant width (hs) up to a pole height (ds) and expands laterally as its distance from the pole tongues (6, 6') increases into a heart-shaped contour line with a predetermined core width (A) and core length (L). Geometrically speaking, the pole height (ds), the pole width (hs) and the flare angle ( alpha ) determine the sensitivity of the thin-film magnetic head. In order to obtain a high play-back voltage at favorable useful signal/noise ratio, the transition of the contour line of the magnetic core halves (4') in the region of the pole height (ds) has the shape of a continuous curve free of abrupt changes, preferably a circular section with a radius (r) at least 1.5 times the system height (hs). Thin-film magnetic heads of this type are particularly suitable as write/read heads in magnetic disk stores of high recording density.

Title: Device for channelling away the cleaning agents and/or liquids used for cleaning vertical surfaces, preferably the facades of buildings
Inventor: WINDEL GEROLD
IPC: E04G23/00
Filed: 1988-11-24
Abstract: In the case of cleaning and renovating vertical surfaces, in particular the facades of buildings, much use is made of cleaning agents, strippers and the like which run down the facades with the cleaning liquid and, in the immediate vicinity of the discharge regions of the facades, pass into the soil and thus also into the groundwater. This constitutes a considerable disadvantage because the agents used often pose problems from the point of view of environmental protection. In order to provide a device for channelling away the cleaning agents and/or liquids used for cleaning vertical surfaces, preferably facades of buildings, which is not only simple to produce and to apply, but, furthermore, also permits reliable collection and channelling-away of the cleaning agents and/or liquids used, with the result that they can be disposed of without difficulty, the invention proposes that said device be composed of sealing mouldings (1) and collecting gutters (2), and the sealing mouldings (1) be fastenable releasably on the vertical surfaces (3) and be connected to the collecting gutters (2) such that those sides of the sealing mouldings (1) which are directed away from the vertical surfaces (3) open into the interiors of the collecting gutters (2), and the collecting gutters (2) are in connection with collecting receptacles (Figure 1). <IMAGE>

Patent DE-3843216-A1 (DE)
IPC: G11B20/00
Filed: 1988-12-22
Abstract: The invention concerns a method of retrieving data carriers from an automatic data-carrier archive, in which the data carriers are identified by means of an externallly scannable tag carrying an external identification before they are taken out of a data-carrier store by a manipulator device. In order to improve the tolerance to errors and the error-handling capability, it is proposed that an internal identification corresponding to the external identification contained on the externally scannable tag is recorded on the data-carrier medium. After inserting the data carrier in a read/write device, the internal identification is read and compared with the external identification. The result of this comparison is used to determine the subsequent treatment of the data carrier within the archive.

Title: Casting pipe for conveying molten metal into a mould
Inventor: THIEMANN HANS
IPC: B22D41/50
Filed: 1989-01-28
Abstract: To convey molten metal into the mould, the casting pipes are equipped with valves to regulate the emergence of the molten metal from the casting pipe. For this purpose, use is made of rods which run centrally through the casting pipe and greatly narrow the flow cross-section for the molten metal. As a result of this, so-called freezing-up of the molten metal in the casting pipe can very easily occur. Moreover, it is also inevitable here that, owing to the molten metal flowing through between the outer wall of the rods and the inner wall of the casting pipe, considerable material wear on the rods and on the casting pipe occurs, which not only results in a reduction of the working life of the rods and of the casting pipe, but also leads to contamination of the molten metal. According to the invention, these shortcomings are avoided in that the throttling member (4) is arranged laterally on the outside of the casting pipe (1) and is operatively connected to an adjusting device (7) situated laterally on the casting pipe (1) and outside the molten metal. <IMAGE>
