Abstract: A heat exchanger for an internal combustion engine may include a plurality of first tubular bodies and a plurality of second tubular bodies for being flowed through by a gas. A plurality of first intermediate spaces may be disposed between the plurality of first tubular bodies defining a plurality of first coolant paths for being flowed through by a coolant. A plurality of second intermediate spaces may be disposed between the plurality of second tubular bodies defining a plurality of second coolant paths for being flowed through by the coolant. The plurality of first coolant paths may be fluidically connected to a first coolant distributor configured to distribute the coolant to the first coolant paths and a first coolant collector. The plurality of second coolant paths may be fluidically connected to a second coolant distributor configured to distribute the coolant to the second coolant paths and a second coolant collector.

Abstract: A heat exchanger for a motor vehicle may include a plurality of flat tubes for a first medium and two tube bottoms. The plurality of flat tubes may be aligned in a longitudinal direction and stacked spaced apart from one another in a stack direction to form a heat exchanger block. The plurality of flat tubes may each extend into the two tube bottoms. The heat exchanger may also include two guide plates which close the heat exchanger block such that a plurality of flow spaces for a second medium are delimited between the plurality of flat tubes. A plurality of depressions may be disposed in a longitudinal end region of one of the guide plates, may protrude into a respective flow space, and may follow a shape of the adjacent flat tubes area by area such that the at least one guide plate surrounds the plurality of flat tubes.

Abstract: A rescue device has a motion detector and a transceiver that operates either to transmit a locating signal, which can be tracked by others, or to receive and track a locating signal transmitted by another. A control logic circuit suppresses transmission of the locating signal by the transceiver unless a motion signal, generated by the motion detector responsive to the user's movement, indicates that the user has not moved for a predetermined time interval. Thus, the rescue device can transmit the locating signal when the user is motionless, providing notice that the user is immobile and aiding others in locating the user. When the receiver is operating, it guides the user in locating the source of a transmitted locating signal to aid the user in locating an immobilized person or a building exit. An override can be provided to allow transmission of the locating signal regardless of movement.

Abstract: The invention relates to optionally solventless two-component polyurethane surfacers containing finely divided fillers in a high pigment volume concentration based on a polyfunctional isocyanate component (B) and a polyol component (A) which is liquid at room temperature and which consists of mixture components containing isocyanate-reactive hydroxyl groups with an at least predominant content of branched-chain polyols (A1) containing ester and ether groups, which contains at least a proportion of the finely divided fillers and, optionally, the additives and which, for application, is mixed with the isocyanate component (B) and applied as a mixture which can still be processed by shaping.

Abstract: Dry products in flake or granulate form suitable as a paste base may be obtained by drying a mixture, containing approximately 30 to 80% by weight of water, of from(a) 30 to 95% by weight of carboxymethylated and/or alkoxylated starch,(b) 3 to 40% by weight of a cellulose ether, and(c) 2 to 40% by weight of a water-dispersible polymer or water-soluble polymer, and(d) optionally, conventional additives, such as preservatives, wetting agents, fillers and the like,in a thin layer on a surface heated to 80.degree. to 200.degree. C. The dry products obtained do not undergo physical separation and are readily dispersible or self-dispersible in water.

Abstract: A storage stable adhesive for PVC plastics, particularly post-chlorinated PVC plastics, containing a basic mixture of 5 to 30% by weight post-chlorinated PVC and 95 to 70% by weight of an organic solvent, a stabilizer combination of effective quantities of organotin compounds and alkali metal carbonates from the group consisting of ammonium, lithium, sodium and potassium carbonates and also standard additives, such as impact modifiers, antioxidants and UV stabilizers can be included in the basic mixture. The composition has improved stability when stored in tin plated steel containers.

Abstract: An adhesive composition and a method for its use in bonding rigid PVC elements. The adhesive composition comprises: (1) a first dissolved PVC polymer having a K-value of about 58 .+-. and a second dissolved PVC polymer having a K-value of about 45 to about 52; (2) at least one cyclic organic solvent; and (3) at least one non-cyclic organic solvent.

Abstract: An aqueous alkaline paint stripper composition which forms a foam when dispersed from an aerosol container comprising:A. from 47 to 94% by weight of an aqueous solution containing from about 5 to about 40% by weight of at least one strongly alkaline substance,B. from 1 to 8% by weight of at least one surfactant,C. from 5 to 30% by weight of at least one propellant,D. from 0 to 5% by weight of at least one foam stabilizer and/or thickener, andE. from 0 to 10% by weight of at least one water-miscible organic solvent,and a method of stripping paint using the above paint stripper composition.

Abstract: A method of providing a foam accoustical insulation, thermal insulation, and/or moisture-barrier, in which a polyurethane prepolymer composition is applied to a substrate in situ and then expanded and cured using water pre-applied to the substrate, ambient atmospheric moisture, and/or added atmospheric moisture.

Abstract: An aqueous concentrate for the cleansing of foodstuffs of animal or vegetable origin, consisting of:(a) from 0.1% to 10% by weight of water-soluble to water-dispersible proteins,(b) from 0.01% to 3% by weight of water-soluble polymers having a molecular weight of at least 10,000,(c) from 1% to 15% by weight of a water-soluble sequestering agent,(d) from 0.01% to 1% by weight of water-soluble food preservatives,(e) from 0 to 0.5% by weight of food colors and food odorants, and(f) the remainder to 100%, water.
