Abstract: A disposal bag for a vacuuming device, wherein the disposal bag has a pressure equalization matrix. The pressure equalization matrix has openings that are designed to effect pressure equalization between a first region and a second region of a collecting tank of the vacuuming device. The vacuuming device can preferably be a construction site vacuum cleaner, wherein the collecting tank of the vacuuming device is designed to receive the disposal bag and the dust sucked in by the vacuuming device is collected and contained in the disposal bag. A method for producing a disposal bag, and to the use thereof in a vacuuming device is also provided.

Abstract: An arrangement of components in a portable wet vacuum cleaner, wherein the wet vacuum cleaner includes a container for collecting a liquid-dirt mixture. The component arrangement is characterized, in particular, by a sloping sealing plane as the upper termination of a collecting container of the wet vacuum cleaner, wherein the sloping sealing plane includes a filter unit. In a second aspect, the invention furthermore relates to a wet vacuum cleaner having a component arrangement of this kind.

Abstract: Recombinant viral vectors which coexpress heterologous polypeptides capable of assembling into defective nonself-propagating viral particles are disclosed. The viral vectors as well as the viral particles can be used as immunogens and for targeted delivery of heterologous gene products and drugs.

Abstract: The present invention provides recombinant DNA viral vectors which co-express lentivirus genes encoding structural and enzymatic polypeptides capable of assembling into defective nonself-propagating viral particles. The viral DNA vectors as well as the viral particles can be used as immunogens and for targeted delivery of heterologous gene products and genes.

Abstract: Recombinant avipox viral vectors which express heterologous polypeptides capable of assembling into defective nonself-propagating viral particles are disclosed. The recombinant avipox viruses can be used to produce significant amounts of the heterologous polypeptides in avian or non-avian cells. Preferably, the recombinant avipox virus is a fowlpox virus. The viral particles can also be used as immunogens and for targeted delivery of heterologous gene products and drugs.
