This invention is directed to a wearable air cleaner where an air cleaning device is incorporated into a hat. The air cleaning device includes a fan unit to pull air through the device. The air cleaning device also includes ultraviolet light to disinfect the air and pushes the disinfected air in front of the wearer for breathing.

Wearable air cleaner with ultraviolet light disinfection

An improved trailer hitch is presented. The tractor trailer has a main trailer frame, the main trailer for hauling cargo. To help couple a trailer cab to the trailer frame a swivel box having a spring-loaded locking pin and a permanent hinge pin is coupled to a tongue that is used to couple the trailer cab and the trailer frame. The swivel box swivels or swings the tongue to a position to accommodate a misaligned trailer cab easing the coupling process.

This invention is directed to a wearable air cleaner where an air cleaning device is incorporated into a hat. The air cleaning device includes a fan unit to pull air through the device and an air filter to capture particles in the air. The air cleaning device also includes ultraviolet light to disinfect the air and pushes the filtered and disinfected air in front of the wearer for breathing.

Substituted 1,2,4-triazolo[1,5-c]pyrimido[1,4]azines have been found to have potent bronchodilator activity.

Substituted 1,2,4-triazolo[1,5-A]triazines as bronchodilators

The invention is directed to a covering remover, the covering including roofing shingles. Removal of roofing shingles and other coverings presently requires hand tools, such as crow bars, hammers, shovels and nail pullers. This manual method is time and labor-intensive, as roofing needs to be removed in small individual sections. The present invention comprises a cylinder assembly with a rotatable shaft within the cylinder. Strapping is attached to and extends from the cylinder. A lifting force underneath the covering to be removed is accomplished when the cylinder assembly is rotated about its axis. This rotating assembly lifts whole sections of roofing and when removed from the cylinder, leaves the rolled-up section in a bale for convenient disposal.
