Brushing device with illumination features

Abstract: The present disclosure relates to an oral cleansing device with illumination features. In one example, the device includes a housing including an aperture, such as a button aperture, defined therethrough, a diffuser connected to the housing and configured to span over the aperture. The device also includes a blocking member positioned over a portion of the diffuser and connected thereto and a lighting array received within the housing and at least partially aligned with the blocking member such that light emitted from the lighting array is transmitted to an exterior of the housing by traveling around the blocking member and through the diffuser.

A wastewater treatment system

Abstract: A means for treating wastewater wherein the means comprises a storage treatment tank having a receiving chamber for accommodating waste products to be processed, an aeration chamber adjoining the receiving chamber to receive fluids comprising solids and liquids therefrom, a settling chamber for separating solids from liquids, and means for transferring aerated fluid from the aeration chamber to the settling chamber. The tank further includes a second settling chamber to receive liquid from the first settling chamber and feedback means connected with the receiving chamber and with the second settling chamber for returning the higher density portions of the contents of the latter to the receiving chamber for further processing. The aeration chamber is provided with a diffuser to introduce air upper pressure into the aeration chamber in order to aerate the contents thereof. The system also comprises additional feedback means connected with the receiving chamber and with the firstmentioned settling chamber for transferring a portion of the contents of the latter to the receiving chamber for further processing. A discharge chamber is also provided, to receive fluid from the second settling chamber and to discharge liquid portions thereof through a tank outlet. The method of using the apparatus of the invention comprises filtering wastewater from the receiving chamber through a screen and into the aeration chamber where the wastewater is aerated, transferring the aerated wastewater to a settling chamber where the higher density portions of the wastewater are allowed to settle to the bottom of the chamber, and transferring these higher density portions to the receiving chamber for further processing.
