Abstract: A chemical injection system. The chemical injection system includes at least two Venturi injectors in parallel. Each of the Venturi injectors having an injector housing with a longitudinal cavity having the shape of hourglass. One end of the longitudinal cavity forms an injector inlet, and the other end forms an injector outlet. Each of the injector housings also has a first vertical cavity forming an injector port located at the hourglass constriction. The injector inlets are fluidly coupled together to form a shared injector input and each of the injector ports is fluidly coupled to an individual valve. Each of the injector outlets is fluidly coupled to the input a separate T-filter and the outputs of the T-filters are fluidly coupled together to form shared T-filter output.

Abstract: In one aspect, the present disclosure relates to a motorized tie-down device having a housing, a flexible strap having a first end attached to a reel, and a carabiner attached to a second end of the flexible strap. The housing can include a power supply comprising one or more rechargeable batteries, an electric motor coupled to receive power from the power supply, a control to activate the electric motor, the reel, and a worm drive assembly operatively coupled to the electric motor and the reel and configured to transfer rotation from the electric motor to the reel.

Abstract: The foundation wall and floor slab drain is a device that is designed to control the buildup of mold in basements by enabling the water that drains from wall to be channeled into a French drain that is provided there under. The device is installed during construction of the footing, foundation wall, and floor slab. The device is further defined as an elongated planar member with a plurality of tubes linearly aligned thereon, and which collectively form an assembly. Both the elongated member and the plurality of tubes are bent to form a right angle. A vertical portion of the assembly is adapted to interface against a foundation wall and a side surface of a floor slab. A horizontal portion of the assembly is adapted to interface between a bottom surface of the floor slab and a top surface of a footing.

Abstract: A light strand support apparatus having two slots for receiving and securing a light strand. Each slot is held fixed with respect to other. The apparatus holds each light strand at a fixed distance from a surface or object as the slots are supported by a central component that extends from a support. The support is configured to rest flush against a given surface or object.

Abstract: Compositions and methods are provided for the treatment of bacterial infections with live bacterial agents. The invention also provides methods of producing bacterial preparations for medicinal use. The inventive compositions and methods can be useful in preventing or treating bacterial infections in multicellular organisms by infecting and lysing the bacterial target.

Abstract: A brick comprising in combination a body element having oppositely disposed ends and spaced apart surfaces intermediate the ends, with the body element having a pair of elongated cavities extending between the oppositely disposed ends and through the spaced apart surfaces and a channel extending between the cavities. An aperture extends between each cavity and a respective one of each of the ends. Electrical lighting components are mounted in each of the cavities and include a light bulb socket secured to a wall of the cavity, a light bulb secured in the socket, first electrical wires connected to each light bulb socket through the channel, and second electrical wires connected to each light bulb socket and exiting from the body element through each aperture, such that adjacent bricks may be wired together.
