Title: Apparatus for cleaning the waste air occurring on a textile machine
Inventor: DERICHS JOSEF DR ING
IPC: D01H11/00
Filed: 1989-01-11
Abstract: The cleaning of the waste air occurring on a textile machine of fibre fly, thread residues and dust is usually carried out in filter chambers with filter screens or filter bags which precede the suction fans. During the cleaning of the filter media, which can be difficult, above all on account of the sticky reviving agents precipitated on them, the textile machine can be used only to a restricted extent. In open-end rotor-spinning machines, for example, only the spinning mode can be maintained. The apparatus according to the invention makes use of a fine-pore filter medium (42) which is several times larger than the active filter surface and which is provided as a stock (43) on the filter chamber (40). There are means which bring the filter medium out of the stocking position into an active filter position and from there, after it has been used up through contamination, into a disposal position. The exchange of the filter medium (42) can take place automatically by means of a conveying device (50) in dependence on the degree of contamination which is detected by a contamination sensor (66). <IMAGE>

Inventor: BREUER GUENTHER
IPC: G09B29/10
Filed: 1989-01-25
Abstract: Unfolding or unrolling maps and bound town maps or leafing through them is tiresome, makes the overview more difficult and adversely affects the useful life of the means. The goal is the combination of the map material on a small flat area, while at the same time retaining the property of being read easily. The individual pages of a geographic unit are combined on a slide in a strongly reduced manner and imaged in an enlarged manner on a ground-glass screen by displacing in individual images. The method makes it easier in particular for the motorist to find his destination in unknown regions.
Patent DE-3904102-A1 (DE)
Title: Housing comprising ventilated hollow elements for lining existing cellars to form shelters
Inventor: SCHWARZLOSE HOLGER DR ING
IPC: E04H9/06
Filed: 1989-02-11
Abstract: Current industrially prefabricated shelters give rise to high costs and can be subsequently installed only with a considerably high outlay. The intention is thus to provide a process which permits the lining of cellars to form ground-protection shelters by a simple, cost-effective construction method, without changing the substance of the structure. For this reason, a closed sheet-metal housing is fitted together from standard elements and other hollow elements which are screwed together, which housing is spaced apart from all the cellar sides by means of screw-bolts and can be rapidly dismantled locally in an emergency. The door case is flanged on the housing. The housing ceiling is reinforced, in the case of large cellars, by supported beams. By virtue of controlled air guidance in the casing area outside the housing, the cooling potential of cellar walls and floor is rendered useful. The waste air cools the cellar door in the event of fire. The housing erected by a grid construction method is suitable for installation in cellars of any size. They are predominantly used in homes, where they can be assembled by the building owner himself. <IMAGE>

Title: Burning off soot in catalytic diesel engine exhaust system - in cold conditions, by localised hot air stream maintaining ignition temp.
Inventor: MARTENS THOMAS DR
IPC: F01N3/021
Filed: 1989-06-13
Abstract: Exhaust gas from a diesel engine first passes through a honeycomb body coated internally with catalyst for converting NOX to N2 and CO to CO2. The exhaust fumes continue through a second honeycomb body (6) whose catalytic coating reducess the temp. for ignition of soot particles in the fumes. For use especially at low engine speeds or when external atmos. temp. is low, a supply of pre-heated auxiliary air is directed through the central areas of the honeycomb bodies. This air may be drawn from the exterior, to be heated by a final heat exchanger (7) downstream of the honeycomb bodies and returned via conduits (13, 14) to the fume inlet end. An auxiliary electrical heater is  incorporated in the air flow path. The area of the honeycomb bodies subjected to heated auxiliary air is sufficient to ensure soot ignition temp. is reached even during poorestt operating conditions. ADVANTAGE - Avoids risk of soot accumulating in cold conditions and then suddenly burning off, producing temp. which could damage catalytic honeycombs.
