An insulation system, for use with transport vehicle structural frame members, having at least a first structural frame member and adjacent structural frame members in a transport vehicle. Each structural frame member has a first free end, a second end attached to a transport vehicle wall, and two sides disposed between the first and second ends. The system has at least one flexible insulation member wrapped over the first free end and over at least portions of the two sides, and at least first and second self-retaining foam insulation members positioned on each side of the wrapped first structural frame member and disposed in compression fit between each side of the wrapped first structural frame member and each of the adjacent structural frame members. The foam insulation members impart one or more compression forces on the flexible insulation member to secure it in place without use of any fastener device.

The invention relates to a method for feeding a sample into an analysis branch of a liquid chromatography system, in particular a high-performance liquid chromatography system. A solvent or a solvent mixture from at least one solvent branch is supplied as volume flow {dot over (A)} into the analysis branch. At least one sample from at least one sample branch is fed as volume flow into the analysis branch within a predetermined time interval. The volume flow {dot over (A)} is reduced to an extent during the predetermined time interval, and a volume flow resulting from the sum of the volume flows {dot over (A)} and remains substantially constant in the analysis branch. The invention further relates to a sampler for carrying out a method of this kind.

A ventilation system for a passenger transit vehicle that comprises a passenger compartment. The ventilation system comprises a variable speed fan for providing outside air to the passenger compartment, wherein within a given ambient temperature range, the speed of the variable speed fan is controlled such that the air speed produced by the variable speed fan increases with increasing ambient temperature. The ventilation system further comprises a duct system fluidly connecting the variable speed fan to an air diffuser that directs the air from the variable speed fan towards the passengers within the passenger compartment. The cross sectional area of the duct system decreases along its length for providing substantially constant air pressure along its length. The ventilation system is able to provide outside air into the passenger compartment at an air flow speed of greater than 0.15 m/s.
