Title: Method for controlling the ventilation of rooms and buildings in which open radioactive and/or toxic substances are employed
Inventor: BRENDER ROLAND
IPC: F24F11/00
Filed: 1983-06-15
Abstract: In the previous control methods for ventilating rooms and buildings in which open radioactive and/or toxic substances are employed, large quantities of air are required, which is energy-consuming and leads to large quantities of special waste due to the used filters which result. This is remedied by a reduced air volume flow, in that the actual values of the room temperature, radioactivity and concentration of harmful substances and of the differential pressure at the filter are compared with desired values and, if they deviate from the desired values, the supply-air and/or exhaust-air flow are set accordingly by actuating regulating elements.

Inventor: HAHN WINFRIED
IPC: B01F23/57
Filed: 1983-08-05
Abstract: The process permits a carbon black compound to be mixed with a highly viscous liquid to form a suspension or dispersion without splashing and foaming. The carbon black compound contains a liquid (water, naphtha, alcohols, esters or a solvent mixture), the boiling temperature of which is below the temperature of the hot highly viscous liquid, which can be a mineral oil, distillation residue oil, bitumen, asphalt or another highly viscous hydrocarbon. The carbon black is uniformly and finely distributed in the hot highly viscous liquid and is present in a form also suitable for production from synthesis gas by partial combustion. The liquid-containing carbon black compound is incorporated under pressure into the hot highly viscous liquid and preferably dispersed in a shear force-generating dispersion apparatus of high power. The process is reliable in operation and economical on a large industrial scale without complex pretreatment of the carbon black compound.

Patent DE-3403989-A1 (DE)
Title: Standard hexagonal ground plate
Inventor: BEIER GUENTER ING GRAD
IPC: E01C9/08
Filed: 1984-02-04
Abstract: The invention relates to a standard fracture-resistant hexagonal ground plate for making a temporary roadway by mutual engagement of the hooks and eyes arranged on the edges. The susceptibility to cracking between the hooks and eyes is significantly reduced in the improved ground plate by increasing the resistance to gravity at the corners. Breaking of the ground plate is avoided, retaining the dimensions, the weight and the same material, in that, on tearing of the ground plate with extreme overloading, at the corners between the hooks and eyes, the force transmission runs elastically in a meandering manner via the divergently outwardly running reinforcement ribs to the crack-protection ribs via the hooks and eyes. The ground plate is in this connection mainly subjected to bending and torsion.

Patent DE-3411141-A1 (DE)
Title: Transformer with a heavy-current bushing
Inventor: HENRICI PETER ING GRAD
IPC: H01F27/28
Filed: 1984-03-26
Abstract: For such transformers having windings which are connected in delta on series-connected iron-core limbs, it is known to use a cross-section outside the heavy-current bushing arrangement as a compensated heavy-current line, which cross-section is assembled in cross-section from three conductors in the form of a V to form a three-pointed star. According to the invention, three triangular connectors (4), which are in the form of plates and whose main extent planes are in each case rotated through 120 DEG  with respect to one another, are located in the transformer directly on the inside of the heavy-current bushing arrangement (3) and at the same time represent a part thereof, the outgoing lines (5) of the central winding (1) being cross-braced with respect to one another and being guided parallel to one another in vertical planes to downwardly pointing wedges of two triangular connectors (4), while in contrast the outgoing lines (6) of the two other windings (1) are guided to the triangular connectors (4) without cross-bracing. This arrangement can be produced easily and economically, primarily in the field of heavy-current bushings and, as a consequence of its largely compensated design, is free of hot spots and for this reason can be used even for current intensities over 80 kA. <IMAGE>

Title: Method for connecting two intersecting rods and an apparatus for carrying out the method
Inventor: RUNKEL ADOLF
IPC: E04G21/12
Filed: 1984-05-23
Abstract: The present invention relates to a method for connecting two intersecting rods, in particular reinforcing rods for a steel-reinforced concrete structure, and to an apparatus for carrying out the method. In the method, a pincer-like tool is used, which is first of all closed around the rods to be connected, after which one wire is fed forwards, cut off and clamped, whereupon the pincers are opened again and the two rods are ejected from the pincer region via a tappet. Finally, the pincers close again and perform a rotary motion to twist the ends of the wires around the reinforcing rods to be connected. The apparatus for carrying out the method has, as essential elements, completely closed wire-guiding channels in both pincer arms of the pincer-like tool and the pincer arms provide control of the clamping device and the cut-off device.
Patent DE-3420201-A1 (DE)
Title: Method and apparatus for removing excess material from forgings
Inventor: DIEMER DONALD J
IPC: B21K23/04
Filed: 1984-05-30
Abstract: A forging is taken up by a split ring which supports the forging at a circumferential wall and an upper circumferential flange. The forging and the split ring are supported by a locating device when a deburring device is moved in the longitudinal direction in order to debur the flange and an aperture in the forging. A punching tool with a hardened cutting edge is moved axially through the aperture in the forging, interacting with a cutting edge on the locating device in order to deburr the aperture. A punching tool with a cutting edge simultaneously interacts with a cutting edge of the split ring in order to deburr the upper flange. The split ring prevents a central area of the forging from being expanded outwards over its circumference under the action of the punching tool forced through the aperture. The interaction of the deburring tool and of the split ring prevents the upper part of the forging, which adjoins the upper flange, from being drawn inwards into the aperture in the forging due to the interaction between the punching tool and the forging. In this way, the aperture and the flange of the forging are deburred simultaneously without deformation of the forging.

Title: Method and means for producing a cultivation trough for horticultural plants and a cultivation trough produced according to these
Inventor: ERNES EGIDIUS ALOYSIUS HUBERTU
IPC: A01G9/02
Filed: 1984-11-13
Abstract: In the production of a cultivation trough for horticultural plants, use is made of a plastic web, the material composition and cross-sectional profiling of which allow a sharp-edged cold forming of longitudinal strips of the web. Longitudinal edge strips of the web form upright side walls and a central strip a bottom for the trough. One of the longitudinal edge strips can be divided by a corresponding widening in such a manner that, in addition to a side wall, a cover for the cultivation trough can also be bent off in one piece. A free edge strip of the cover can, by a further bend, form an overlapping edge. Likewise it can be advantageous, instead of a cover designed in one piece with the trough, to close the trough with a loose cover with overlapping edges.
