Patent DE-3245520-A1 (DE)
Title: Device for moving a curtain or the like
Inventor: WIEGAND PETER
IPC: A47H5/02
Filed: 1982-12-09
Abstract: Devices serving for moving curtains are to allow a harmonious, even pleating outside the stored position of the latter for opening and closing the curtain. By means of the device of the invention, a constant pleating is allowed when moving the curtain in the region outside the stored position. For this purpose, rail carriages bearing the curtain or the curtain halves (10 and 11) (pulling carriage 16; running carriage 22) are connected to one another by V-shaped collapsible toggle levers (23). The toggle levers (23) allow the curtain or the curtain halves (10, 11) to be folded together in the stored region thereof whereas, outside the stored region, the toggle levers (23) are brought into a virtually stretched position by support plates (29, 30), in which position the toggle levers (23) are supported on the support plates (29, 30) during the further movement of the curtain halves (10, 11). In this manner, the spacing of the rail carriages (pulling carriage 16, running carriage 22) and thus the pleating of the curtain halves (10, 11) outside the stored region of the curtain always remain approximately the same. <IMAGE>

Title: Table for presenting merchandise
Inventor: WANZL RUDOLF
IPC: A47F3/14
Filed: 1983-02-11
Abstract: In the case of tables of the existing type, it is usual to connect the walls by screwing to the table top, or the tubular uprights, or to the frame bearing the tubular uprights, or to fasten them in an interlocking manner by engaging means located on the tubular uprights. These types of fastening are costly. It is also disadvantageous that the table tops have to be delivered with walls already screwed on in order to save the recipient unreasonable assembly work. However, table tops with screwed-on walls take up considerable space when despatched. The table according to the invention for displaying merchandise avoids the disadvantages mentioned by part of the section (12) of each hook (11) which is located in the tubular upright (2) protruding beyond the upper limitation (14) of the respective slit (13) when each wall (7) is in the fitted state. As a result, the walls are fixed in their position without any additional fastening means being necessary. The individual components of the table (1) can be despatched in a space-saving way. The assembly effort is reduced. <IMAGE>

Title: Data processing system
Inventor: ARNDT GERHARD DIPL ING
IPC: G06F13/40
Filed: 1983-09-20
Abstract: This system consists of a stationary central data processing system and at least one mobile decentralised unit which is subordinate to the central data processing system and can be connected to it and detached from it again, which exhibits devices for inputting system-external data, for exchanging data with the central data processing system in the connection state, for storage, outputting and for visual representation of system-external input data or data transmitted from the central data processing system. In the connection state, the central data processing system accepts, in addition to the data stored in it, also the data stored in the decentralised unit up to the time of the connection establishment, processes all these system data if necessary and again stores the data possibly processed in the central system or in the decentralised unit. After that, any change data entered during the connection state into the central data processing system or into the decentralised unit produce corresponding data changes both in the central data processing system and in the decentralised unit. When the connection is released, the decentralised unit automatically combines the change data supplied to it with the data stored in it.

The spring extends between the swivel lever and the base frame. <IMAGE>
Patent DE-3338971-A1 (DE)
Inventor: HUININK HEINRICH DIPL ING
IPC: B60C15/02
Filed: 1983-10-27
Abstract: A vehicle wheel on which can be mounted a pneumatic tire which essentially includes rubber or rubber-like synthetic material, and has a carcass with load-carrying cords which are anchored in the bead regions of the tire via inextensible core rings. The wheel has a rigid rim with laterally outwardly disposed rim flanges; disposed axially inwardly of these rim flanges on the radially outer side of the rim are seating surfaces for the tire. To minimize disrupting effects on the tire tread, while at the same time improving the emergency operating conditions, a support member is disposed axially inwardly of the seating surfaces on the rim. This support member has a diameter which is greater than the diameter formed by the rim flanges. In the region of a given rim flange, the tire wall extends laterally outwardly from a given core ring in a substantially flat manner, and in particular in an angular range of from 0 DEG  to 20 DEG  relative to the axis of rotation of the tire. The carcass neutral line passes through the same region of a given rim flange in such a way as to avoid a turning point. The core rings are eccentrically disposed in their head regions in such a way that when the tire is mounted, the inner diameter of the tire in these bead regions is less than it is during mounting of the tire.

Patent DE-3411812-A1 (DE)
Title: Screw connection
Inventor: ROGG KARL-HEINZ DIPL ING
IPC: F16B37/00
Filed: 1984-03-30
Abstract: The invention relates to a screw connection for various components provided with an anti-corrosion coating. The coating, for example varnish or underbody protection, is softer than the basic material. In the region where the nut or the screw head bears against a flat side, directed towards the components, of a machine element, the screw connection exhibits arcuate or circular circumferential beads which run concentrically with respect to the screw axis, are like cutting edges, and penetrate into the coating. These beads are provided directly on the bearing side of the nut or alternatively of the screw head and should contribute to reducing settlement phenomena, in particular in dynamically loaded screw connections for clamping surfaces provided with varnish or with other soft coatings. At the same time, the screw or the nut of the screw connection exhibits, in the region of the threads, cutting or peeling edges which have a self-cleaning action in that the peeled-off particles of the coating can be removed, as required, in order to keep dirt away from the threads and to permit effortless screwing-in.

Patent DE-3429059-A1 (DE)
Title: Fitting
Inventor: KRIEGER HELMUT
IPC: A44B11/18
Filed: 1984-08-07
Abstract: A fitting for trimming the sail of a surfboard comprises two cross struts mounted so as to be movable in relation to one another. A rope end is wrapped around one of the cross struts. The two cross struts are moved towards one another under the action of the tensile stress occurring in the rope, as a result of which the rope end is clamped fast. The two cross struts are preferably components of lugs which are connected in an articulated manner at their ends opposite the cross struts and which together form a trimming shackle. A rope secured to the mast foot of the sail mast is run via a leg of a lug and is closed to form an eye. It is then put through an eye of the sail and, after passing through the second lug, wraps around the first lug, whereupon it is again passed through the second lug. The rope is then clamped fast between the two cross struts of the lugs. Exact trimming is possible in the simplest manner with the fitting thus formed. The outer ends of the legs of one lug, which essentially has a U-shaped configuration, are bent over and enclose a leg of the other lug. Both lugs are made from stainless steel wire.

Title: Telecommunications network, in particular mobile radio network, with network-uniformly changeable keys
Inventor: DIEDERICH HANS G DIPL ING
IPC: H04W12/04
Filed: 1984-08-29
Abstract: In a telecommunications network, in particular a mobile radio network, with a plurality of subscriber terminal devices and at least one central station, the encryption provided for data prone to misuse, such as subscriber identifiers, is intended to be modified by the central station in a network-uniform manner in the event of the key becoming known. For this purpose, a key memory SP containing n keys is provided in each subscriber terminal device with an activation signal decoder ASD connected upstream in order to decode n-1 key addresses. In the event of misuse of the initially used first key being detected, a network-uniform activation signal AS which is inserted in a concealed manner in the useful signal is transmitted by the central station over a relatively long time period to the subscriber terminal devices, said activation signal providing one of the subsequent n-1 keys instead of the first key. The activation signal AS can be concealed in the useful signal in time division multiplexing, e.g. through permutation of an address bit in an address block which is inserted in the useful bit stream and is otherwise occupied with blank bits, or in frequency division multiplexing, e.g. through the addition of sub-audio frequencies to the useful band. For network-wide modification of the key once it has become known, the address of the key memory SP is modified by the activation signal AS in the central station only (Fig.). <IMAGE>

Title: Shaft-furnace tap and drilling tool for drilling open a taphole
Inventor: BRIELER WILFRIED
IPC: C21B7/12
Filed: 1984-10-16
Abstract: The invention relates to a shaft-furnace tap, especially for blast furnaces having body diameters amounting to up to 15 m. To reduce the flowing distance of the jet of liquid metal with slag issuing during the tap, the taphole is advantageously made two-stage or multi-stage according to the invention, the diameter increasing discontinuously in steps towards the outside. This results in pressure losses and particularly in reduction of the flow velocity of the issuing jet, so that the flowing distance in the tapping runner is reduced. Furthermore, the invention relates to a drilling tool in a guided positionable taphole-drilling machine for making a taphole of the type described above. This is achieved in an especially advantageous way by means of a drilling tool, in which, on the drill rod carrying a drill bit on its end face, a further drill bit is displaceable and is brought to bear non-rotatably against a driving cone at an axial distance from the drill bit located on the end face. By means of a drilling tool of this type, not only the guidance of the taphole-drilling machine can be maintained, but also the at least two-stage taphole can be produced in a single operation.
