Granted: 1995-11-14
Abstract: An  odor-removing  filter  approaching  the carbon- particle loading of a filled filter may be formed by spraying adhesive against one or more faces of a porous, fibrous, air-permeable mat, depositing carbon particles or other odor-removing particles of a size to compliment the void size of the mat on the adhesive coated face or faces of the mat and then driving the particles into the mat and thereafter curing the adhesive to lock the particles into the mat.  The adhesive bond of the particles to the mat is improved  by  working  the particles  against  the adhesive- coated fibers.  An overspray of an adhesive may also be utilized to further improve the retention of the particles.  So-called "clean filters" may be produced according to the method disclosed, wherein a white, fibrous mat has carbon particles loaded on one face while the opposite face appears white or "clean". An indicator filter notifying the user when the filter becomes grease laden may also be formed following the methods used herein.

Abstract: The glycosides of resorufin derivatives have the general formulae Ia and Ib <IMAGE> in which R<1> is hydrogen, R<2>, R<3> and R<5>, which can be identical or different, are hydrogen, halogen or a lower alkyl group, R<4> and R<6>, which can be identical or different, are hydrogen, halogen, a cyano, lower alkyl, lower alkoxy, carboxyl, lower alkoxycarbonyl, carboxy-lower alkyl, lower alkoxycarbonyl-lower alkyl or an optionally mono- or disubstituted carboxamide group or the group  -COO-(CH2CH2O)n-R<7> in which R<7> is hydrogen or a lower alkyl group and n is an integer from 1 to 4, where R<6> can additionally be a sulphonyl or nitro group, and Y is a nitrogen or the group NO. These compounds are particularly suitable as chromogenic and fluorogenic substrates for determining the activity of corresponding glycosidases or oligosaccharide-cleaving enzymes. The glycosides are obtained by reacting resorufin derivatives with a mono- or oligosaccharide or a 1-halogeno derivative thereof, whose hydroxyl groups are substituted by customary protective groups. This initially results in per-O-substituted glycosides, which can be converted into the claimed compounds by elimination of the protective groups. The glycosides are used as chromogenic and fluorogenic substrates in diagnostic agents for detecting glycosidases or oligosaccharide-cleaving enzymes. The resorufin derivatives employed as starting materials in the preparation of the compounds are also claimed.

Abstract: A method and apparatus for inspecting a danger alarm system, such as a fire alarm system, having a plurality of discrete alarm units which are connected to a central station having a means for cyclically sampling and connecting the alarm units to a like plurality of evaluators permits the alarm units to be connected individually or in groups to an inspection display without suppressing the display of an actual alarm signal which may be received during the inspection. A first report of an alarm unit to be inspected is evaluated as an inspection report and an actual alarm report from the same alarm unit arriving after the inspection report is evaluated and displayed as an alarm report. Given alarm units which emit multi-level or analog signals, the alarm unit signals are evaluated in the central station with two threshold circuits, the evaluator at the central station being switched during an inspection to a less sensitive state and the inspection signals being evaluated by a lower threshold stage and a true alarm signal which may occur during an inspection being evaluated as such by an upper threshold stage.
