Abstract: According to some embodiments, sewer alarm devices and apparatus are provided for detecting the presence of liquid within a pipe. In some embodiments, the devices and apparatus include a housing including a top portion and a bottom portion, and a probe housing, extending from the bottom portion of the housing to a bottom surface area of the probe housing and sized to fit within an interior of a wye connector, the wye connector having an interior extending into an interior of the pipe. At least a first probe is disposed within the probe housing and exposed to an area between the bottom surface area of the probe housing and the interior of the pipe.

Abstract: In a preferred embodiment, an apparatus, including: a generally horizontal support tray to support a mailbox; a post interface bracket for attachment to a mailbox support post; a spring attached to said generally horizontal support tray and said post interface bracket and disposed so as to return said generally horizontal support tray to its normal position after said generally horizontal support tray is rotated out of position; and a connection pivot bolt connecting said spring and said post interface bracket, said connection bolt being sole method of fixed attachment of said generally horizontal support tray and said post interface bracket.

Abstract: A mailbox post includes a movable joint, an elastic element connected to said post at two locations, one on each side of the joint, supportive against tension force between the two locations and connected to the post at a third location between the two locations, supportive against twisting force on the joint.

Abstract: A plurality of layers of thread, each sculptured by stringing, each higher layer strung around a larger diameter opening, forming a portion of a wing, and so strung symmetrically, forming a pair of wings, and forming a butterfly sculpture.
