Patent DE-3835915-A1 (DE)
Title: Adjusting device for pressure bands
Inventor: KINNE KLAUS
IPC: B65H5/02
Filed: 1988-10-21
Abstract: The adjusting device for pressure bands is used especially in rotary feeders. The adjustable pressure bands act on the stacking material (2) transported from the upper table (1) via a deflecting drum (4) and lower table (11) to the separating element (9). The pressure bands (6) are guided via the band pulleys (28, 29, 34) which rotate on a pivoting shaft (20) or are held by pairs of pivoting levers (22, 23). The adjustment of the pressure force is brought about via the rotation of the pivoting shaft (20), for which purpose a gearwheel (21) is positioned on the latter. This gearwheel (21) is in engagement with a worm wheel (19) which is moved via a shaft (15) by hand or by means of a stepping motor (16). The motor (16) is controlled by a switching unit (14) which, for this purpose, is connected to two sensors (12, 13) positioned along the lower table (11) above the stacking material (2). To guarantee a pretension which allows for the format of the stacking material, one pivoting lever (23) of each pair of levers is connected to the frame (42) via a tension spring (39). <IMAGE>
Patent DE-3836051-A1 (DE)
Title: Spraying device and control method therefor
Inventor: FORSTER KLAUS
IPC: B05B1/30
Filed: 1988-10-22
Abstract: The invention relates to spraying devices of the type in which a free-flowing substance emerges from a spraying head (11) for applying the substance to an object in a non-atomised fashion. In known devices of this type, pauses in operation lead to gumming up of the nozzle (12) by the substance, which generally has adhesive properties. The invention is intended to remedy this disadvantage. The invention provides a spraying device, in the case of which the emergence of gas after closure of the nozzle (12) through which the substance emerges can be permitted and blocked after a delay in an automatic fashion, the duration of emergence of the gas blown through the closed nozzle (12) to clean it being preferably controllable. This is a simple and reliable way of ensuring that the substance to be processed by the spraying device does not stick fast. The spraying device according to the invention is especially well suited for the non-atomised application of varnishes, paints, adhesives or oil to an object. <IMAGE>

Title: Melt cylinder (barrel) for injection-moulding or extruder machines for plastics
Inventor: RUETTEN KARL HEINZ
IPC: B29C48/03
Filed: 1988-11-18
Abstract: The thermoplastic materials introduced in solid form into the melt cylinder are conveyed by means of a screw to an injection nozzle (die) provided in the cylinder head at the free end of the melt cylinder and are thereby plasticated (plasticised) under the effect of heat. The melt cylinder is formed by a carrier cylinder, ensuring its stability, and an inner cylinder of wear-resistant material. To ensure the dimensional stability of the bore of the inner cylinder for the material being injected (extruded) and for the purpose of in-plant exchangeability of melt cylinders, the inner cylinder, bearing against the carrier cylinder over the length of the bore of the latter, is of an exchangeable design and is detachably connected to the said carrier cylinder in such a way that it is secured in relation to the latter against axial displacement and twisting. On the outer circumference of the inner cylinder there is preferably provided a collar which comes to bear against a stop arranged in the cylinder opening intended for it in the carrier cylinder. The end face of the inner cylinder and a mating face on the cylinder head are in contact with each other. From the cylinder opening, a bolt can be inserted into an overall recess provided in the carrier cylinder and in the inner cylinder.
Patent DE-3839835-A1 (DE)
Title: Threaded rods and bolts of thermoplastic materials reinforced with continuous and chopped strands
Inventor: KRUEDENER RUDOLF PROF DIPL ING
IPC: B29D1/00
Filed: 1988-11-25
Abstract: By the selective introduction of on the one hand continuous strands in the core or shank region and on the other hand chopped strands in the thread or outer region, it is intended to reduce the flow characteristics of thermoplastic threaded rods and bolts while at the same time increasing the ultimate mechanical strengths. The chopped strands additionally bring about an improvement with regard to producing the threads by means of cold rolling processes, whereby an additional increase in strengths is obtained. A pultrusion-extrusion process serves for producing the threaded parts.

Title: Hypocaust and/or stove-wall brick
Inventor: CARL SIEGFRIED
IPC: F24B1/06
Filed: 1989-01-09

Title: Method and arrangement for controlling the pressing force of a deflection-setting roll
Inventor: SCHUWERK WOLFGANG
IPC: D21G1/00
Filed: 1989-02-22
Abstract: In the case of a deflection-setting roll having a series of hydraulic supporting elements, the pressure (yi) in the individual supporting elements is controlled in dependence on the pressing force or mean linear force within a given setting range (xo-xm) in accordance with linear functions (fi) of the type yi = aix + bi. If the pressure (yi) at the limits (xo, xm) of the setting range in one supporting element reaches a threshhold value (ym, O), then outside the normal setting range (xo-xm) the pressure of this supporting element is kept approximately constant and the other pressures are optimised to minimal deviations from the desired values. <IMAGE>
