Abstract: A system and method for intelligent operation and control of ductless HVAC devices in a manner similar to existing intelligent operation and control of central HVAC systems. In an embodiment, the system and method include using a smart thermostat to separately monitor the room temperature of a room in which a ductless HVAC device is installed, wherein the smart thermostat overrides the standard operation of the HVAC device by setting and re-setting the target temperature of the ductless HVAC device to force it to operate according to settings and algorithms of the smart thermostat which mimic the smart controls available on central HVAC systems.

Abstract: A threaded adapter seal comprising fitting and sealing components for fluid transport applications. Opposed gripping and externally-threaded sections in the fitting component each have hollow interiors, and reduced interior and exterior diameter dimensions of the externally-threaded section compared to the gripping section, provide an interior stop separating the fitting component sections and also provide a radially-extending exterior surface therebetween where an indent is present to improve leak-reducing placement, fit, and performance of the sealing component after threaded adapter seal installation is complete. Improved seating and fit of the sealing component prevent overtightening thread damage during installation. Use of a non-standard thread angle for the externally-threaded section in the range of 1.75 to 4 degrees does also.

Abstract: A molded equipment pad having a top deck, side walls, underlying reinforcing radial ribs, and underlying reinforcing arc-shaped ribs. The arc-shaped ribs may include a series of concentric arc-shaped ribs that are centered on the center of the equipment pad and that extend toward the side walls of the pad and a number of distributed circular hubs. Alternatively, the arc-shaped ribs may include a series of concentric arc-shaped ribs that are centered on the center of the equipment pad that end short of the side walls, a series of opposing arc-shaped ribs that are centered on the corners of the equipment pad, and a number of distributed circular hubs.

Abstract: A UV LED ice disinfecting device. The UV LED ice device is designed to disinfect or sterilize ice, particularly ice made and dispensed from an ice making machine.

Abstract: A system for smart HVAC controllers that is capable of automatically detecting and handling all HVAC control wires, whether the HVAC system is a single or dual transformer system. The system comprises a channel selector for selecting the various channels of an HVAC system for detection, one or more voltage and current limiters for conditioning channel signals for input to a microcontroller unit, a microcontroller comprising an intelligent detection algorithm for operating the channel selector and detecting and handling channel signals, and a one-way gate for protecting against damage from connection of two transformers during wire detection.

Abstract: This disclosure enables various tools for folding pieces of sheet metal and methods of manufacture and use thereof. For example, some of such tools include a first pair of jaws spaced apart from each other at a first distance, a second pair of jaws spaced apart from each other at a second distance greater than the first distance, and a body spanning between the first pair of jaws and the second pair of jaws. By having the second distance being greater than the first distance, a user may use the body to form a primary bend (e.g., a hem) on a piece of sheet metal via bending the piece of sheet metal via the first pair of jaws, or vice versa, and then a secondary bend of the primary bend to form a desired shape (e.g., an S-shape) on the piece of sheet metal via the second pair of jaws, or vice versa.

Abstract: A system for combining and spraying fluids that includes a principal reservoir for holding a carrier fluid; an electric pump in communication with the principal reservoir; a power source for energizing the pump selectable between a rechargeable 12-volt battery and a 110-volt AC line; at least one auxiliary reservoir for holding an auxiliary fluid to be controllably mixed with carrier fluid being drawn from the principal reservoir; a selector valve for selecting which if any of the auxiliary fluid(s) are to be combined with the carrier fluid; a Venturi tube for combining streams of carrier fluid and selected auxiliary fluid(s) in a predetermined ratio which may be varied as desired; and a spray wand in fluid communication with the Venturi tube for discharging the selected fluids.

Abstract: A projectile launching apparatus for cleaning the inner surface of a tube by forcing a projectile through the tube, comprising: a main body containing a breech chamber terminating in an exit port, wherein the breech chamber is provided with a loading port in a side thereof for radially loading a projectile into the breech chamber; a slide disposed on an exterior surface of the main body, the slide being axially movable between a first position wherein the loading port is exposed for loading of a projectile into the breech chamber and a second position wherein the loading port and the breech chamber are sealed; a gas gun operatively connected to the main body in pneumatic communication with the breech chamber; and an exit nozzle connected to the exit port and being connectable to a first end of the tube to be cleaned.

Abstract: This disclosure enables various brackets and methods of manufacture and use thereof. For example, a bracket may have a first clip, a second clip, and a third clip, where the second clip spans between the first clip and the third clip to enable the bracket to be capable of simultaneously engaging (e.g., holding, clamping) a first tubular member (e.g., a tube, a socket, a bulb) by the first clip and the third clip and a second tubular member (e.g., a tube, a socket, a bulb) by the second clip as the first tubular member extends along the second tubular member.

Abstract: A latching magnetic float switch with a single fastener mounting clamp and pivoting toggle bar magnet interrupting an electrical circuit to stop fluid production once actuated by an initially offset float magnet first rotating a small distance in response to liquid accumulation in the collection pan upon which the switch is mounted, the float magnet then achieving a strong snap-locked latching magnetic engagement with the toggle bar magnet solely through building magnetic attraction between them, engagement continuing until the float magnet is manually reset into its original offset positioning. The 2-part clamp with a rotating curved/bowed clamp arm can mount the switch securely to both metal and plastic liquid collection pans with differing draft angles, and also provides a clamp base configured for elevation adjustment of the float housing relative to pans having different wall height dimensions and fluid production shut off when detected fluid depth is less than 0.5 inches.
