Patent DE-4000890-A1 (DE)
Title: Fabric separation - uses diverging air streams to give fabric buoyancy for movement
Inventor: LANGE HERBERT
IPC: B65H3/14
Filed: 1990-01-13
Abstract: The appts. to carry and move fabric sections such as components to be assembled into garments, uses an air stream (23) directed at a diverging acute angle from the fabric surface (20) to give buoyancy from the jet (22) on the fabric (20). Pref. the fabric (20) is presented to the jet assembly on a permeable carrier or grid, and the air stream (23) is generated by a number of air channels from a radial direction on a plane parallel to the fabric (20) surface, or at a diverging acute angle, with narrow gaps between them. To lay the fabric (20), the surface air streams are stopped and a vertical air stream is directed downwards at the material, pref. as a pulse. The jet assembly (22) is brought to the fabric stack, to detach the top layer (20), and is lowered to penetrate it with jet needles, and blown air separates the top layer from any other clinging layers. The air stream (23), at supersonic speed, is delivered through small openings and channels through a ring jet (24) parallel to the upper surface of the fabric (20) or at an acute angle, particularly along an air guide surface angled at an increasing amt. outwards from the fabric plane. ADVANTAGE - The operation gives a simple jet action which effectively separates thin and large fabric sections for handling.

Title: Exhaust gas layout from e.g. boiler plant - has wet desulphurisation, heat exchangers, solids filters and heat carrier so that system prevents corrosion of pressurising fans
Inventor: MUELLER-ODENWALD HERMANN-EUGEN
IPC: F23J15/00
Filed: 1990-03-17
Abstract: A process produces protection for outlet side pressurising fans used in the wet desulphurisation of exhaust gases and the heat transfer side beyond the fan of a circulating regenerating heat exchanger, with heat-storing material moved relative to the connecting passages in the waste gas of a furnace plant. Heat is indirectly transferred to the desulphurised gas on the inlet side of the pressurisation and by a liq. heat-carrier, using tubular heat transfer surfaces of plastic material by cross-counterflow; solids are sepd. out from the residual drops of the gases on the heat-transferring surfaces; and, by temp. changes and/or vibrations in the heat-transfer surfaces to divert the stream of gas and make it turbulent, these solids are removed again. Pref. material for the tubular heat-transferring surfaces is polyethylene or fluorpolymer such as polyvinylidene-fluoride. ADVANTAGE - The system prevents corrosion or contamination of the fan. It minimises the quantities of wash water used for cleaning down.

Title: Appts. to remove water from slag sand - has funnel below sand hopper with overflow edge for rising water level
Inventor: CALMES MARC
IPC: C21B3/08
Filed: 1990-11-26
Abstract: The appts. to remove water from slag sand, particularly from the hopper for a blast furnace, has a lower outlet opening (12) of the hopper (8) opening into an outlet funnel (14), with a larger dia. than the outlet opening (12) and its upper edge (18) above the level of the outlet opening (12). A ring-shaped passage (16) is between the hopper outlet (12) and the upper edge (18) of the funnel (14) to allow extracted water to flow over the funnel edge (18). Pref. water outflow valves (24,26) are positioned at different heights in the side wall of the outflow funnel (14) above the hopper outlet (12).

The cylindrical outlet can be extended by an apron with a slight conical downwards expansion.  The outflow funnel can expand conically to its upper edge.  The outflow funnel height can be adjusted. A circular ring filter can be inserted between the outflow funnel and the outlet connection of the hopper (8). ADVANTAGE - The appts. gives a max. water extraction rate, without the use of filter surfaces.

Patent DE-4132926-A1 (DE)
Inventor: HALLAS ERNST DR RER NAT
IPC: G01N21/15
Filed: 1991-10-04
Abstract: The invention relates to an arrangement for cleaning and protecting the measuring optics in exhaust-gas test devices for internal combustion engines against contamination with the aid of a flushing-air stream. Such a protection of the measuring optics by flushing air is generated in known devices by a suitable pump or a fan passing fresh air from the environment via a feed system adapted to the measuring arrangement to the measuring optics. As the measuring system does not permit complete separation of the flushing-air stream and the exhaust-gas stream, the exhaust-gas flow rate is affected by the flushing air, and the measurement results are thus falsified. An arrangement for supplying flushing air is therefore to be described, in which the influence of the flushing-air stream on the exhaust-gas stream is reduced. This is achieved by the flushing-air rate being controlled as a function of the exhaust-gas flow rate in the measuring arrangement. The arrangement according to the invention makes it possible to advantageously achieve a flushing-air flow rate which is equal to the exhaust-gas flow rate, so that the mutual influence of the flushing-air stream and the exhaust-gas stream is minimised. <IMAGE>
