Patent number: 8658588Abstract: A composition for cleaning hard surfaces which is self-adhering to a wet or dry hard surface through a plurality of flows of water thereover. The composition is a gel having a viscosity of about 600,000 cP to about 1,500,000 cP and is capable of being manually applied, i.e., in absence of an applicating dispenser, to a hard surface. The gel composition with high viscosity provides for continuous cleaning until depletion, or may be used for one-time cleaning at any time between application of the composition to a hard surface and depletion of the gel composition.Type: GrantFiled: January 9, 2012Date of Patent: February 25, 2014Assignee: S.C.

Patent number: 8328894Abstract: A device is provided that is capable of circulating air throughout a personal space as well as collecting and preventing the build up of dust and other particulate matter by drawing in air from the surrounding environment and removing some dust, allergens and other such particulate matter therefrom. The filtered air is then expelled out of the device and back into the surrounding environment. The device includes a housing defining an interior space having a motor and fan assembly disposed therein. The housing includes an inlet with a filter provided therein such that air drawn in through the inlet is filtered. The air is then expelled through a circumferentially disposed outlet. The filter element preferably includes a lock and key system configured to prevent operation of the device in the absence of a properly keyed filter.Type: GrantFiled: August 20, 2009Date of Patent: December 11, 2012Assignee: S.C.
