Patent DE-3323929-A1 (DE)
Title: Process for producing weldable large pipe sheets of fine grain structure
Inventor: GRAEF MICHAEL DR ING
IPC: C22C38/04
Filed: 1983-07-02
Abstract: In a process for producing weldable large pipe sheets of fine grain structure from a microalloyed steel by thermomechanical rolling, a steel having 0.05 to 0.07% of carbon, 1.5 to 2.0% of manganese, 0.01 to 0.4% of titanium, 0.001 to 0.003% of sulphur, 0.005 to 0.008% of nitrogen, 0.25 to 0.40% of silicon, 0.03 to 0.05% of aluminium and up to 0.08% of niobium, the remainder being iron and usual impurities, is produced. The titanium content is adjusted to the nitrogen content. Continuously cast slabs are heated to 1120-1160 DEG C. In this way, niobium precipitations are dissolved and, on subsequent cooling during deformation, predominantly precipitated as strength-increasing niobium carbide. A coarsening of titanium nitride precipitations, taking place during this heating, proves to be harmless. The deformation is at least 55%. This is followed by thermomechanical rolling at a temperature of at most 850 DEG C and by finish-rolling at a temperature above 650 DEG C. This may be followed by intensified cooling to temperatures between 550 and 500 DEG C.

Abstract: This is an underframe for mobile shelf units, having a frame construction made of longitudinal bars and bearing cross-pieces which connect the longitudinal bars, and having in each case two bearing limbs, arranged at a given spacing from one another, for bearing running wheels and driving wheels on shaft portions which run orthogonally to the bearing cross-pieces and are mounted in the bearing limbs, the running and driving wheels being arranged between the bearing limbs of the bearing cross-pieces. In the region of the shaft portions, the bearing limbs have bearing recesses which are open at the bottom. Bearing shells which are open at the bottom are moulded onto the bearing limbs in the edge region of the bearing recesses. Two rolling bearings on one shaft portion receive a wheel between them in each case and are inserted from below with said wheel - running wheel or driving wheel - in two mutually associated bearing shells in each case. <IMAGE>

IPC: B05B1/00
Filed: 1984-05-10
Abstract: The invention relates to an atomiser head for spray guns for pneumatically spraying liquids in the form of an attachment component for conventional spray guns, which component brings about a substantial reduction in noise emission. The nozzle openings (4) for the liquid are shaped in such a way that a flat jet of liquid is formed. The nozzle openings (15) for the compressed air are arranged on the two sides of the nozzle openings (14) at a small distance such that the compressed air atomises the liquid in the jet of liquid which is flowing out and spreads it out in a fan-like manner. Further nozzles (16) for the compressed air assist the intake of the liquid. The nozzle openings (15) extend at the angle () of 0 DEG  or greater than 0 DEG  with respect to the direction of the axis of the spray jet and extend away from the direction of the axis of the spray jet at an angle (b) of 0 DEG  or greater than 0 DEG . The nozzle openings (16) extend at the angle () of 0 DEG  or greater than 0 DEG  away from the direction of the axis of the spray jet. The nozzle opening (14) can be shaped as a gap or can be formed from bores lying one next to the other. The attachment component (11) can be fitted onto conventional spray guns in place of an air cap and can be screwed tight by means of a holding ring. <IMAGE>

Title: Hollow body made of thin metal sheet and a method and apparatus for its production by blow forming
Inventor: VOTTELER ALBRECHT DIPL ING
IPC: B21D26/02
Filed: 1984-05-19
Abstract: In order to design a hollow body with an outer skin which is, in general terms, three-dimensionally curved so that the hollow body can be produced from a relatively thin metal sheet and has internal reinforcement, the outer skin consists of at least two metal sheets (13, 14; 15, 16) bonded together adhesively, the adhesive bonds b concerned being in the form of islands and being arranged in such a way that the unbonded surface has a grid shape and at least the inner sheet (14, 15) forms a reinforcing grid corresponding to the grid shape and having channels (21, 22). Production is effected by blow forming by means of pressurised fluids, during which process the channels are also formed. The mould 2, 4 concerned consists of a mouldable material such as gypsum, concrete or casting resin. The invention can be used to advantage in particular for prototypes and small batches. <IMAGE>
Patent DE-3418795-A1 (DE)
Title: Process and device for producing concrete slabs
Inventor: MATTERN HERBERT
IPC: B28B11/04
Filed: 1984-05-19
Abstract: In order to protect the face side of concrete slabs, spacers made of an elastic material are provided between the individual slabs of a stack. The spacers, which are applied in various manners, require additional operations which reduce the productivity of a plant. According to the invention the spacers are injected by means of a plurality of hot glue nozzle-application units onto the slab which is still in the mould. This takes place simultaneously with the discharge of the slabs from the mould, so that no additional operations are necessary. The constructional outlay is extremely small, since passage openings (16) for the hot glue only have to be provided in the discharge cone (8) of the discharge device (4). The nozzle application units (15) are, in an extremely simple manner, to be suspended on stationary mounts which are designed such that adjustment of the nozzle application units (15) in a longitudinal and transverse direction in dependence on the slab size is possible. <IMAGE>

Title: Adjusting device for cutting units arranged next to one another and capable of being moved to a mutual spacing
Inventor: REITTER WERNER
IPC: B23D59/00
Filed: 1984-12-12
Abstract: The invention relates to an adjusting device for cutting units (2-5), e.g. the circular knives of a longitudinal cutting machine for webs of endless fabrics, arranged next to one another and capable of being moved to a mutual spacing. In order to measure the spacing of the individual cutting units (2-5), use is made of a distance measuring device (10) which operates in accordance with the triangulation measuring principle, is arranged fixed next to the units (2-5), and into the virtually parallel light beam (14) of which it is possible to insert selectively insertable reflectors (6-9) of the individual cutting units (2-5). The point (15) of incidence of the light beam (14) incident on all the reflectors (6-9) at the same angle of incidence is projected by a measuring optical system (12-13). The position of the projected point of incidence is a measure of the distance, and can therefore be used to adjust the cutting units (2-5) to the desired positions. <IMAGE>
