Patent DE-4119787-A1 (DE)
Inventor: SAGEMUELLER FRANZ DIPL ING
IPC: F26B17/26
Filed: 1991-06-15
Abstract: For continuous conditioning, particularly thermal conditioning, such as cooling, warming, drying, moistening and the like, of particulate material, preferably vegetable particulate material such as cereals, herbs, tobacco and the like, the particulate material is continuously conveyed mechanically along a conveyor belt leading through a closed, tunnel-like conditioning station and is exposed, in the conditioning station, to the influence of a substantially gaseous heat exchange medium guided to the conditioning station through at least one aperture. The heat exchange medium is tightly bundled on passing through the aperture (6, 6', 6'') and is then guided as a free jet (8) through the particulate material, forcing the particulate material aside, in such a way that deflection of the jet (8) in all directions is effected at a wall (2) of the conditioning station lying opposite the aperture. The deflected parts (10) of the jet are sucked, by the pumping action of the free jet, downwards and back into the range of action of the free jet, and the particulate material is compressed, in a movement aligned at right angles to the free jet, between the vacuum region (9) of the upward-directed free jet and the excess pressure region of the downward-directed parts of the jet. <IMAGE>

Title: Continuous yarn fluid treatment appts. - has two displaced synchronised rollers within container with min. recesses for yarn travel between and around them
Inventor: WEDLER KLAUS DIPL ING
IPC: D06B3/06
Filed: 1991-06-29
Abstract: The appts. to apply a continuous treatment to a yarn, in a fluid medium, has at least two rollers at a gap from each other, on parallel axes and in floating mountings, with synchronised drive. The yarn is drawn from its supply to pass continuously round the rollers, and between them, in a number of axially displaced coils. It is then taken off by a unit synchronised with the roller drive. The rollers, with the yarn coiled round them, are immersed in a container with the medium. Recessed zones are at the container, only for the yarn passage and for the rollers, at least partially filled with the medium, so that the vol. ratio between the medium and the yarn is minimal. USE/ADVANTAGE - The appts. is for the application of a wet medium to continuous yarn material such as in dyeing, mercerising, impregnation or drying. It applies an even treatment and effect, such as in dyeing, with min. dyestuff.

Inventor: LASSNIG GUENTHER
IPC: F02B75/02
Filed: 1991-12-17
Abstract: A portable current generating unit (10) uses a three-phase current generator (12) which operates at low output voltage levels. The generator (12) is driven by a two-stroke engine (16) which can be started manually.

Thus, as the number of supply voltages connections increases, the power of the drive motor (16) increases. In the pre-excitation phase of the generator (12) a current passes through the excitation coil (43). This is coupled out of the magnet generator (43) of the magnet ignition of the drive motor (16) by an induction spool (95). USE/ADVANTAGE - For small devices, e.g. windscreen wipers, pumps etc which must be driven at low voltages. Simple and safe to operate and lightweight and compact.

Abstract: The invention relates to a process and a device for the sealing connection of pipes (2, 4) which consist of glass, metal or ceramic materials and are fitted together to form flue-gas lines. The sealing system according to the invention is distinguished by the fact that it can be used for both waste-gas lines and, for example, for cross-sectional reductions in chimneys since the sealing material is used such that the overlapping pipes (2, 4) are connected in a gas-tight manner, even in the case of fluctuating pressure conditions, and that the sealing material (8) is sufficiently acid-resistant, water-resistant and temperature-resistant in order to be able to use it for channelling away hot, acid gases. In a preferred embodiment, the pipes (2, 4) are fixed with respect to each other before the inorganic sealing material (8) is applied. The pipes are either fixed by a rapidly hardening adhesive (6) which is applied in a punctiform manner, or else they are secured with respect to each other by a pipe clamp (14) which is arranged on the outer circumference of the pipes. <IMAGE>
