The plug has: a first section; a second section having an outer diameter periphery; and an axial gap between the first section and the second section.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a vessel configured to receive refrigerant from a condenser of the HVAC system, an evaporator configured to receive the refrigerant from the vessel, a first conduit configured to direct a first flow of the refrigerant to a first inlet of the evaporator, and a second conduit configured to direct a second flow of the refrigerant to a second inlet of the evaporator. The second inlet is above the first inlet relative to a vertical axis.

Abstract: Embodiments of the present disclosure are directed toward purge units of vapor compression systems, and methods of control thereof, that improve efficiency by selectively activating and deactivating the purge unit in response to one or more conditions to, for example, enable refrigerant-to-air ratios within the purge unit within certain industry standards while still minimizing the durations of the purge cycles. For example, in certain embodiments, these conditions may include conditions within the chiller condenser, time since last purge activation, time since last venting of non-condensables, and combinations thereof.

For example, in certain embodiments, these conditions may include conditions within the chiller condenser, time since last purge activation, time since last venting of non-condensables, and combinations thereof. By reducing an amount of time that the purge unit would be active without removing a substantial amount non-condensables from the vapor compression system, present embodiments reduce the power consumption of the purge unit, as well as the vapor compression system as a whole.

Abstract: Embodiments of the present disclosure are directed toward purge units of vapor compression systems, and methods of control thereof, that selectively activate and deactivate the purge unit in response to one or more conditions to, for example, control refrigerant-to-air ratios while still minimizing the durations of the purge cycles. For example, in certain embodiments, these conditions may include conditions within the chiller condenser, time since last purge activation, time since last venting of non-condensables, and combinations thereof. By reducing an amount of time that the purge unit would be active without removing a substantial amount non-condensables from the vapor compression system, present embodiments reduce the power consumption of the purge unit, as well as the vapor compression system as a whole, while still being responsive to prevent or mitigate a loss of efficiency due to a substantial accumulation of non-condensables in the condenser of the vapor compression system.

Abstract: The invention provides an animal treatment block for applying a treatment to an animal against the action of biting insects, including a body including a carrier medium, a structural means, incorporated into the carrier medium and an active ingredient incorporated into the carrier medium. The body, including the carrier medium with incorporated active ingredient and structural means, may be mounted such that an animal can readily contact the body, whereby the active ingredient is applied to the animal in a controlled manner, through application of the carrier medium. The invention also relates to variants thereof and methods of use.

Abstract: Embodiments of the present disclosure relate to a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system including a refrigerant loop and a purge system configured to purge the HVAC&R system of non-condensable gases. The purge system includes a liquid pump configured to draw a first refrigerant flow from an evaporator, a controllable expansion valve configured to receive the first refrigerant flow from the liquid pump and reduce a temperature of the first refrigerant flow, and a purge heat exchanger, which includes a purge coil. The purge coil is configured to receive the first refrigerant flow from the controllable expansion valve, a chamber of the purge heat exchanger is configured to draw a mixture of the non-condensable gases and a second refrigerant flow from a condenser, and the purge heat exchanger is configured to separate the non-condensable gases from the second refrigerant flow utilizing the first refrigerant flow.

Abstract: Methods and systems are disclosed for controlling user creation of data resources on a software platform for storing and executing data resources for multiple users. The methods and systems may be performed using one or more processors or special-purpose computing hardware and may comprise receiving from a user a user request to create a data resource on the software platform, the user request comprising, or identifying, a specification indicative of the data resource and a user identifier associated with said user. A further operation may comprise performing verification of said user using the user identifier to determine if said user is permitted to create or modify the data resource indicated in the specification in accordance with a predetermined set of permissions.
