Abstract: An air-conditioning system for air-conditioning an interior of a vehicle may include a fan for driving air. The system may include a control device that may include a circulating air inlet for drawing in circulating air from the interior, a fresh air inlet for drawing in fresh air from an environment of the vehicle, and an air outlet. The control device may include a control valve adjustable between a circulating position and a fresh air position. The control valve may include at least one non-return check valve. The non-return check valve may permit a flow to pass through the control valve in one direction and block the flow in an opposite direction.

Abstract: The invention relates to a motor vehicle air conditioning unit (1) which is used to temper the front area of a motor vehicle. Said motor vehicle air conditioning unit comprises one first blower (2), an evaporator (4) and a heater (5) and, optionally, an additional heater (6) and an air channel (10) which is used to ventilate the rear. At least one additional, second blower (13) comprising a blower housing (14) is arranged in the air channel (10) which is used to ventilate the rear. Said air channel (10), which is used to ventilate the rear, is a cold air channel.

Abstract: The invention relates to an air-conditioning unit, in particular, a motor vehicle air-conditioning unit, whereby a part of the housing has a different embodiment for air-conditioning units with differing zones and at least the arrangement of a fan, an evaporator and a heater is the same for the different-zoned air-conditioning units. The housing of the air-conditioning unit may have various embodiments for different versions and/or may be varied by add-on or exchangeable components and, for a multi-zoned embodiment of the air-conditioning unit, a bypass for the floor region is provided in a region of the housing, which diverts from the heater, whereby said bypass is embodied in a region which is redundant in an air-conditioning unit with fewer zones.

Abstract: Multimeric hybrid genes encoding the corresponding chimeric protein comprise a gene sequence coding for an antigenic region of a protein from a first pathogen linked to a gene sequence coding for an antigenic region of a protein from a second pathogen. The pathogens particularly are parainfluenza virus (PIV) and respiratory syncytial virus (RSV). A single recombinant immunogen is capable of protecting infants and similar susceptible individuals against diseases caused by both PIV and RSV.

Abstract: An immunogenic composition capable of producing a respiratory syncytial (RS) virus specific immune response in a host immunized therewith comprises purified, inactivated RS virus which is substantially free from cellular and serum components and which is non-infectious, non-immunopotentiating, immunogenic and protective. The virus is grown on a vaccine quality cell line and harvested virus is purified under non-denaturing conditions to be substantially free from cellular and serum components. The purified RS virus is inactivated using ?-propiolactone, a non-ionic detergent, particularly n-octyl-?-D-glucopyranoside and n-octyl-?-D-glucopyranoside, or ascorbic acid. The immunogenic composition may be formulated as a vaccine for in vivo administration to a human host. The immunogenic composition also may be used in diagnostic applications.

Abstract: The present invention is directed toward methods for the production of non-infectious, replication-deficient, immunogenic human immunodeficiency virus (HIV)-like particles. These particles are prepared from a recombinant expression vector comprising a heterologous promoter operatively connected to a DNA molecule comprising a modified HIV genome devoid of the long terminal repeat (LTR) regulatory regions but containing at least the gag and pol genes in their natural genomic arrangement. This vector is introduced into mammalian cells to produce the particles of interest. These particles should prove useful in a number of diagnostic, virologic, and immunologic applications.

Abstract: A leak-free drinking beaker comprises a container as well as a lid closing the container, a drink opening which opens into the interior of the container, and a valve extending over the drink opening, which valve is held in the closed position under a certain pretension and can be released against said pretension under the influence of a pressure difference. The valve is a double-acting non-return valve and comprises a flexible valve element and two separate valve seats, the valve element and one of the valve seats has a blocking action in a direction opposed to the direction in which the valve element has a blocking action with the other valve seat.

Abstract: Immunogenic envelope glycoproteins are produced from enveloped virus, such as of the paramyxoviridae family, particularly PIV-3 and RSV, by culturing the virus in the substantial absence of exogenous serum proteins, isolating the virus from the tissue culture, solubilizing the envelope glycoproteins and isolating the solubilized envelope glycoproteins by chromatography.

Abstract: Immunogenic conjugate molecules comprising at least a portion of a capsular polysaccharide of a Streptococcus strain linked to at least a portion of an outer membrane protein of a Haemophilus strain are provided in which the immunogenicity of the capsular polysaccharide is increased. Particularly capsular polysaccharide from Streptococcus pneumoniae are linked to an outer membrane protein of a Haemophilus influenzae strain, which protein may be the P1, P2 or particularly the P6 outer membrane protein. Conjugate molecules comprising the P6 protein linked to a capsular polysaccharide from an encapsulated pathogen other than Streptococcus also are described, in which the immunogenicity of the capsular polysaccharide is enhanced. Such conjugate molecules may be incorporated into immunogenic compositions for protecting a host against disease caused by the Streptococcus strain and preferably also the Haemophilus strain.
