Patent DE-3615109-A1 (DE)
Title: Heat-insulating system for a steep-pitched roof having an insulating layer laid on the roof rafters
Inventor: SCHALK ALFRED
IPC: E04D13/16
Filed: 1986-05-03
Abstract: The invention proposes a heat-insulating system for a steep-pitched roof, in which insulating panels (6), consisting of bonded mineral fibres with a compressive strength of >/= 50 kN/m<2>, are laid on the roof rafters (1) such that they are lined up in rows flush against one another and cover the surface area, there being provided, between the insulating panels (6) and the roof rafters (1), a closed profiled-board shuttering (2; 3) and a diffusion-tight sheet (4) on top of this. In each case one sheet (7), which is open with respect to diffusion, but deflects water and is configured such that it is resistant to footfall impact, is adhesively bonded onto the insulating panels (6) themselves, over part of the surface area thereof, which sheet projects on one longitudinal side and one end side, this resulting, at the angles, in overlapping borders (8; 9) by means of which the joints of adjacent insulating panels (6) are covered over in each case. The actual conventional roof covering is then supported on an insulating layer (5) which is configured in this manner. The insulating panels (6) lined up in rows directly one against the other provide a complete-surface insulating layer (5) which is not interrupted by any heat or cold bridges. The specified compressive strength, furthermore, ensures permanent stability of the insulating material in terms of the static load transfer, as a result of which it is possible that the weight of the roof covering, together with wind and snow loads, can be absorbed directly, i.e. without the interposition of any load-transmitting systems, by the insulating layer (5). Moreover, it is possible to walk on the insulating layer (5) without damaging it and it can be used as emergency covering. <IMAGE>

Title: Method and system for data transmission
Inventor: GOTTWALD DIETRICH DR
IPC: G06Q20/00
Filed: 1986-06-11
Abstract: The invention relates to a method and a data transmission system for transmitting data to be protected, in particular in payment transactions with and between banks. According to the invention, a code is modified which is used at the start of a data transmission to identify the user and, if necessary, his equipment to the receiver, in particular the bank, and which is then modified depending on an output signal of a time-dependently operating signal generator, which signal is present at the time of the code modification, in particular depending on the clock time which is accurate to within a second. Furthermore, the modified code is transmitted back to the receiver at the end of the transmission of the actual data block, the validity of the received data block being verified on the basis of the correctly transmitted-back code.

Title: Method for producing a printed circuit board assembly
Inventor: PROMMETTA ANANT DIPL ING
IPC: H01L25/11
Filed: 1986-09-19
Abstract: In the case of a printed circuit board (L) of a printed circuit board assembly, power semiconductors (LH1-LH4) are connected in a thermally conductive manner to a heat sink (K), through cutouts (A). The cutouts (A) are implemented by removing knock-out elements (AE) in the printed circuit board (L), after which the wave-bath soldering of the printed circuit board (L) is carried out. The knock-out elements (AE) fix the position of the power semiconductors (LH1-LH4) during the soldering process and prevent solder reaching the cooling surfaces of the power semiconductors (LH1-LH4) or the component side of the printed circuit board (L). <IMAGE>

Title: Reusable shuttering apparatus for producing a cavity in a hardening material
Inventor: COUWENBERGS PAUL
IPC: E04G11/04
Filed: 1986-09-23
Abstract: The intention is to form a cavity in concrete or the like by means of a reusable shuttering apparatus, it being possible to pull out said shuttering apparatus conveniently after the concrete has hardened. The intention is, however, to avoid sagging of the shuttering apparatus. For this purpose, the shuttering apparatus exhibits a rigid or stiffened inner body (12) and a flexible outer body (14). The outer body can be expanded by a pressure medium, can be enclosed within the hardening material and determines the shape of the cavity to be formed. The inner body (12) imparts the required rigidity to the structure. It is narrower than the cavity. Once the material has hardened, the shuttering apparatus can be relieved of stress. It can then be removed from the cavity for reuse. <IMAGE>

Title: Process and apparatus for extracting metals from waste waters
Inventor: GUETLING WALTER DIPL ING
IPC: B01F25/60
Filed: 1986-10-04
Abstract: In the liquid-liquid extraction of metals from industrial waste waters (effluent) by means of a cationic extractant, the extractant, contained in an organic solvent such as kerosene, is mixed with the waste water to be extracted by means of a mixer pump (1) to give a product stream and passed through a reaction tube (7), the dimensions of which, matched to the size of the product stream, permit a sufficient reaction time. Baffles in the reaction tube ensure a continuous mixing of waste water and extractant. For a selective extraction, the pH is monitored at the outlet (6) of the mixer pump (1) and used for metering a substance serving to adjust the pH, which substance is likewise supplied to the mixer pump (1) via a pipe (5) provided with a metering element (18). The product stream is introduced into a vessel serving as separation stage via a coalescer (10) from the outlet of the reaction tube (7). <IMAGE>

Title: Process and apparatus for using a composite technique to produce body parts
Inventor: FABER NORBERT
IPC: B29C45/14
Filed: 1986-10-10
Abstract: The present invention relates to a process for producing body parts which comprise a thin outer metal sheet which is back-filled with a plastic, for example sheet moulding compound (SMC), and an apparatus for carrying out this process. To prevent moulding compound from inadvertently getting onto the outer surface of the metal sheet, to be coated in a later operation, it is provided within the scope of the present invention that, in a first operation, the edges of the metal sheet to be processed are in each case bent around inwards through 135@ by a width of about 7 mm, that subsequently, after placing the relevant metal sheet into a composite mould, a further bending back of these edges is carried out to form an edge of a U-shaped cross-section and that, finally, liquid moulding compound is introduced into this composite mould and provides the backfilling of the outer metal sheet.

Title: Method and device for controlling the combustion air for a burner
Inventor: EHRENBERG CLAUS DIPL ING
IPC: F23D11/42
Filed: 1987-11-26
Abstract: For the quicker and more reliable starting of a burner (13), it is proposed to supply the combustion air (16) to the burner by means of a blower (18) at variable speed in the cold-start periods and reduced flow rate. Associated directly with the reduced flow rate is a smaller quantity of combustion air which, in the cold state, makes possible an ignitable fuel/air mixture. The lower flow rate of the combustion air (16) causes, for its part, rapid spreading of the ignition, so that even at the start of the burner operation complete combustion of the fed-in fuel is possible. <IMAGE>
