Abstract: Microbial growth in an aqueous cyclodextrin composition is inhibited by the addition of a small, polar base to the composition so as to provide a pH of 10-14 to the composition. The base includes sodium potassium, calcium, magnesium and ammonium hydroxides and carbonates as well as ethylamine, diethylamine and triethylamine. The composition is the resulting alkalaine, aqueous cyclodextrin solution. Adjusting the pH to the alkaline side shows superior antimicrobial action compared to conventional antimicrobial agents.

Abstract: The injection mold for insert-molding a synthetic material around the edge of a filter material comprising at least one particle filter layer and at least one active carbon layer of active carbon particles, is provided with a first mold half and a second mold half which comprise mutually confronting mold walls. In their assembled state, the two mold halves define a receiving space for the filter material, a molding space for accommodating the edge of the filter material and for forming the synthetic material to be arranged by insert molding around the edge of the filter material, with at least one injection channel entering the molding space, and a transition space arranged between the receiving space and the molding space for accommodating the edge portion of the filter material adjacent the edge of the filter material. The transition space is formed with a constricted portion for preventing the leakage of synthetic material from the molding space into the receiving space.

Abstract: A device for producing a flow of fluid such as water or air in a whirlpool tub, having a rotatable impeller, which aspirates water from the space of the tub via intake openings, and ejects a jet of water or a jet of water and air into the space of the tub via outlet openings. The device further has a drive means for driving the impeller via a drive shaft. The driving means is arranged on the driving axle of the impeller but behind the impeller as viewed within the tub. In addition, the device further comprises a driving means such as a hydromotor, a pneumatic drive or a mechanical drive, that are driven by at least one central power drive, and can be serviced and repaired from within the whirlpool tub.

Abstract: A method for underpinning a building comprises arranging at least one elongated supporting element below and substantially parallel to the foundation of the building. A whole side wall of the building may thus be underpinned in a single operation without unnecessarily weakening the existing underground. By coupling a plurality of elongated supporting elements, a kind of large-surface foundation that securely supports the building can be created. The architectonic substance of very old buildings may thus be preserved in a non-aggressive manner. In addition, the underpinning method can be carried out very quickly and at a relatively low cost.

Abstract: A filter device for filtering a fluid, in particular for filtering the air flowing into the passenger compartment of a vehicle. The filter element (10; 60) including filter material (12; 62) with a border (14; 64) and a filter element frame (20; 70) connected with the filter material (12; 62) and extending at least partly along the border (14; 64), the filter element frame (20; 70) being provided with a projecting resilient sealing lip (24; 74) for abutting a device (42, 44, 48) receiving the filter element (10; 60), the sealing lip (24; 74) having at least one bending section (26) of a first thickness (30) facing the filter element frame (20; 70) and at least one enlarged section (28) adjoining the at least one bending section (26) and facing away from the filter material (12; 62), at least a part (40) of the enlarged section being of a second thickness (32) greater than the first thickness (30) in the at least one bending section (26).

Abstract: A process for decreasing the build-up of inorganic incrustations on textiles deriving from water hardness and due to repeated washing cycles with detergent compositions comprises the addition to the washing bath of a non-reducing carbohydrate and/or non-reducing carbohydrate derivative as co-builder.

Abstract: A process for increasing the bleaching efficiency of an inorganic persalt or hydrogen peroxide by adding to said persalt or H.sub.2 O.sub.2 an activating agent. The activating agent is an acetylated gluconic acid derivative, such as N-methyl-N-acetyl pentaacetyl gluconamide, N-methyl-N-acetyl pentaacetyl gluconamide or tetraacetyl gluconolactone. The invention also relates to the acetylated gluconic acid derivatives themselves.

Abstract: The invention relates to a process for increasing the bleaching efficiency of an inorganic persalt and to bleaching and/or detergent compositions suitable for removing stains from textiles or from other products such as paper, cellulose, cork, hair etc. These bleaching and/or detergent and/or anti-incrusting compositions comprise an inorganic persalt and an activating agent comprising an acetylated mixture of sorbitol and mannitol wherein the molar ratio between the bleaching activator and the persalt is usually from 10:90 to 50:50. The bleaching activator having an acetylation degree ranging from 1 to 6 and the weight ratio of sorbitol to mannitol in the mixture is within the range of from 2.5:1 to 4:1.

Abstract: Described is a process for increasing the bleaching efficiency of an inorganic persalt (peroxide) by adding to said persalt (peroxide) an activating agent comprising acetylated sucrose, the average acetylation degree of said acetylated sucrose being from 4.5 to 7.0.
