Title: Synthetic layered silicates modified by quaternary ammonium compounds
Inventor: BORGGREFE GERHARD DIPL CHEM DR
IPC: C01B33/44
Filed: 1981-12-11
Abstract: The synthetic layered silicates (sheet-silicates, phyllosilicates) modified by quaternary ammonium compounds (QAC) have the general formula: n Na2O x 1 MgO x x SiO2 x y Al2O3 x z H2O; n = 0.05-0.15; x = 0.8-1.3; y = 0.03-0.1; z = 1-3. The quaternary ammonium compound to be used preferably has two short-chain (C1-2) and two long-chain (C>12) hydrocarbon radicals. Preference is given to layered silicates of the formula: 0.1-0.15 Na2O x 1 MgO x 0.85-0.95 SiO2 x 0.03-0.06 Al2O3 and a water content dependent on the degree of drying, which are modified by dimethyldistearylammonium chloride. To prepare the QAC-modified layered silicates, oxides of Na, Mg, Si and Al are mixed in aqueous solution in a molar ratio of 0.05-0.2 Na2O:1 MgO:1-2.5 SiO2:0.05-0.1 Al2O3, subjected to shearing and crystallised in an alkaline medium by stirring at elevated temperature for several hours, the reaction mixture is diluted and brought to a pH of 7-9 with acid, the QAC is added, the mixture is stirred at elevated temperature, and the solid is separated off. The modified layered silicates are used as thickeners for oils and greases.

Title: Method for manufacturing reinforcing elements for concrete parts
Inventor: CARL HEINZ ING GRAD
IPC: E04C5/06
Filed: 1982-02-22
Abstract: In the method described, two lattice strips which have preferably been manufactured from a welded mesh are laid flat against one another with parallel main planes and connected in this position by welding. The connection takes place in such a way that at least one longitudinal edge remains unconnected. In this unconnected region, the two lattice strips are then spread apart out of the main planes to form the desired profiles. Fig. 4 shows a particularly preferred product of the method according to the invention, in the form of a reinforcing element having a double-T profile for reinforcing ribs in concrete parts. The reinforcing element was manufactured by laying two lattice strips (2, 3) of identical size against one another such that the longitudinal bars (2a' and 3a') situated in their respective longitudinal median lines touched. These longitudinal bars (2a' and 3a') were then connected by point welding (4) to form a basic element (1). Subsequently, the unconnected longitudinal edges (8 and 9) were spread apart from the main plane at right angles. Furthermore, a particularly preferred device for carrying out the method is described, which works substantially fully automatically. <IMAGE>

Title: Contact spring for multiple plug connectors and housings
Inventor: KESSLER OTTO
IPC: H01R13/436
Filed: 1982-09-10
Abstract: The contact spring for plug connectors has a base part which is connected to the parallel leaf spring limb and consists of two box-shaped sections (10, 11) which are arranged aligned one behind the other in the longitudinal axis, are open at the ends and the upper (10) one of which has a rectangular cross-section, while the lower one (11) has a square cross-section. The latter is used for accommodating and attaching a connecting pin (13). Those edges of the upper section (10) which overhang the contour of the lower section (11) are supported against correspondingly arranged shoulders (19, 20) in the upper part (17) and lower part (16) of a two-piece insulating housing (15), for security against axial displacement. The multiple spring strips assembled in this manner are primarily used with connecting pins (13) which can be pressed into a printed circuit board (21) since, as a result of the bending stiffness of the box-shaped sections of each contact spring, a relatively high axial pressing-in force (P) is possible. <IMAGE>

Abstract: A Dynamic Memory Access (DMA) control device for transmitting data between a data transmitter and a data receiver via an external bus formed of a data bus, an address bus and a control bus, and has a multiplicity of data transmitters/receivers and at least one microprocessor connected thereto. The transmission of the data in the external bus depends upon a channel program containing channel transfer commands and channel control commands, and includes a central control unit for addressing, dependent upon a channel command, a microcommand, address and control signals corresponding to the microcommand on an internal address-control bus; an address unit is connected to the internal address/control bus and to an internal data bus wherein addresses of a data transmitter, data receiver and the channel program are stored. The address unit delivers an address and simultaneously computes and stores the delivered address; a data unit provides interim data storage; a byte counter unit is connected to the internal data bus and address/control bus for counting the number of bytes to be transmitted; a data transmitting bus interface circuit is connected to the output of the address unit, to the external address bus and to the internal address/control bus, and to the external data bus. A control register is connected to the internal bus for receiving a channel command word, status words and other control information, from which lines for transmitting control signals extend to the central control unit; the units have devices for independently executing the tasks assigned to them.

Title: Device for scrubbing gases, principally for purifying, moistening and cooling air
Inventor: BOTTLAENDER WILFRIED DR
IPC: B01D46/00
Filed: 1982-12-15
Abstract: The effective moistening area of a device, in which a belt-shaped filter layer, arranged in a V or W shape and wetted by spraying on water, purifies and moistens gas, is enlarged by arranging additional filter layers at the end surfaces of the hollow cavity; the air distribution in the hollow cavity towards the end surfaces is improved by means of an air baffle strip. The seal against entry of air between the covering elements and the filter mount and between the device and the air channel walls is accomplished by using the free ends of the filter mat as sealing packing, which, in addition, absorbs ventilator noise and stops the propagation of structure-borne noise. By dividing the device into a fixed hood with a movable fresh air/vent air flap arranged therein and into a part which can be tilted for maintenance purposes and which contains the moistening device and optionally a ventilator, safety and maintenance require only minimal expenditure.

Title: Closing arrangement having a cylinder and a biaxial coupling device
Inventor: MEYERS PIERRE DIPL ING
IPC: E05B47/06
Filed: 1983-03-24
Abstract: What is presented is a manually actuated closing arrangement which, after the input of a predetermined electrical code on the outside of the door, can be actuated from this side and can be actuated from inside a door without the input of a code and in which the possibility of internal actuation can be cut off mechanically. The closing arrangement presented is based on the use of commercially available locks with a latch and blocking bolt. The lock can be actuated by inserting a cylinder (4) into the lock in the conventional way and by inserting into this cylinder a coupling device (3) which has two spatially separated axles, the second axle being guided outside the region of the lock on to the front side of the door. The entire region of the lock and cylinder can thereby be protected by means of a steel plate against manipulations from outside. <IMAGE>
