Abstract: A felt gripper head contains two regions of felt material each on plates that slide and form a slight angle with respect to each other during engagement with a fibrous substrate material.

Abstract: A system and method for lifting substrate sheets off of a stack of porous sheets one at a time, even though the sheets tend to stick together. A felt tamp is lowered onto the stack of sheets, and as the tamp is raised, a set of edge flickers create a downward force on the corners of the top sheet. This causes the edges of the top sheet to bend downward slightly just enough to pry the second sheet loose from the top sheet. The tamp can then be further raised with only the top sheet adhering to the felt, and the lifted sheet can be deposited at the next station in the process. Periodically, a brush is used to renew the surface of the felt to prevent matting of the felt fibers.

Abstract: A method of extracting a substance comprising the steps of: placing a substrate on which a substance has been adsorbed into a container; feeding a solvent into the container whilst restricting its exit to achieve a predetermined pressure of the solvent in the container, wherein the solvent has a critical point and the predetermined pressure is above the critical point of the solvent; releasing the solvent and an extract comprising extracted substances into a separator; reducing the temperature and pressure in the separator to remove a gaseous portion of the solvent from the extract; collecting the extract remaining from the separator.

Abstract: Connection systems for injection devices are disclosed. Also disclosed are injection devices and methods of using the same. A connection system includes a first and second connection assembly and a coupling assembly to secure the same. The first connection assembly connects to a medicament container, and the second connection assembly has a needle movable toward the medicament container. Removable flexible barriers are disposed on the first and second connection assemblies and can be removed once the connection assemblies are coupled together to form an aseptic connection between the two assemblies. The needle can be moved toward the medicament container to pierce a septum on the container to form a fluid communication between the container and the needle.
