Abstract: A carbon dioxide dry cleaning system features a pair of liquid carbon dioxide storage tanks in communication with a compressor. A sealed cleaning chamber contains the objects to be cleaned. By selectively pressurizing the storage tanks with the compressor, liquid carbon dioxide is made to flow to the cleaning chamber through cleaning nozzles so as to provide agitation of the objects being dry cleaned. Liquid carbon dioxide displaced from the cleaning chamber returns to the storage tanks. In an alternative embodiment, a single storage tank is pressurized via a compressor with gas from the cleaning chamber so that liquid solvent from the storage tank travels to the cleaning chamber through nozzles. The objects in the cleaning chamber are agitated by a rotating basket. After a prewash cycle, liquid solvent from the cleaning chamber is directed to a still. The liquid solvent in the still is boiled through a connection with the head space of the cleaning chamber.

Abstract: A spin-pull blind insert tool utilizes a control system that generates a stop signal based on the relationship between the force values and the motion values derived from the action of the tool mandrel. The improved control system utilizes the shape of the force-deformation curve and not just a given pre-set force value or pull distance. Hence, the control system of the present invention does not require any set-up for changes in panel thickness unless the mandrel is also changed to install a different thread size. This control system develops a force-deformation curve as the fastener is being installed. The stop signal is generated when a pre-set deformation point has been exceeded and the shape of the force curve can be characterized by either of two types. For either type, an algorithm is followed which establishes an optimum stopping point for the installation tool regardless of the panel thickness into which the blind rivet is being installed.
