Patent GB-201315810-D0 (GB)
Title: Extraction cleaning method with temporary suction interrupt
Filed: 2013-09-05
Abstract: A method of cleaning a surface comprising applying cleaning solution to a surface, applying suction to the surface to remove the applied cleaning solution from surface, and selectively interrupting the suction to the surface for a selected time to increase dwell time of the cleaning solution on the surface. In one embodiment, the suction is interrupted when a moveable duct door fluidly and selectively opens and closes a suction leak hole within the working air conduit. In another embodiment, the suction is interrupted when a actuator selectively moves the duct door between the first and second positions within the working air conduit to restrict the working air flow in the working air conduit. The suction reduction selectively increases the cleaning solution dwell time.

Title: Anti-influenza vaccine and process for its preparation
Inventor: LOBMANN MICHELE
IPC: A61K39/145
Filed: 1979-07-02
Granted: 1982-01-14
Abstract: The invention relates to a novel influenza virus strain and to the influenza virus vaccine containing said strain. The new strain, which is the CNCM I-062 strain, is prepared by recombination of the influenza A/PR/8/34 virus strain with the influenza A/Alaska/5/77 virus strain. The vaccine is prepared by allowing the CNCM I-062 strain to grow in the allantoic cavity of fertile hen's eggs, harvesting and freeze-drying the yielded virus material. The strain and the vaccine deriving therefrom are valuable for the immunization against influenza caused by influenza type A (H3N2) virus strains.
