Abstract: A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.

Abstract: An outer space-based reusable manufacturing and assembly system including at least one joint that comprises at least one receiver component, at least one strut that engages the at least one receiver component on the at least one joint and a joining element that provides for engaging and disengaging the at least one joint with at least the at least one strut so that either the at least one joint and the at least one strut are usable for another mission. Two other systems are also disclosed.

Abstract: A process for the preparation of dicyclopentadiene (DCPD) modified unsaturated polyester resins is described where the polyester resins have reduced levels of gel particles.

Abstract: A process for producing a low sulfate organic sulfonate/sulfate aqueous solution from a soluble sulfate containing organic sulfonate/sulfate which comprises forming an aqueous solution of organic sulfonate/sulfate; and passing the aqueous solution of the organic sulfonate/sulfate containing the soluble sulfate over a nanofiltration zone at an elevated pressure to form a retentate with a reduced sulfate content and a permeate containing the soluble sulfate and organic material.
