  • Publication number: 20220057043
    Abstract: A mounting pad system for securing equipment, such as an HVAC outdoor unit or a standby generator, is provided in the form of a lightweight fillable pad member having a plurality of receivers located on a top surface of the pad member. The receivers are associated with attachment points located on the equipment and are used to secure the equipment to the pad. The pad member contains a filling port on its top surface and is configured as a molded hollow shell containing a gelling material which, when mixed with water, provides support to reduce deflection of the pad member caused by the equipment secured to the pad, prevents damage to the pad that would otherwise be caused by the expansion of internal contents upon freezing and prevents leakage of internal contents of the fillable pad in the event of an unintended breach in the hollow shell. The pad member is provided with at least one through-hole that acts as a supporting structure.

  • Patent number: 11226118
    Abstract: An air conditioning apparatus for cooling and/or dehumidifying an interior space, such as the interior of a shelter or tent that provides for simplified manufacturing, simplified inspection and servicing, reduced noise, reduced vibration, reduced weight, increased ruggedness and health monitoring. Structural components of the apparatus are fabricated from foam-filled molded parts with interlocking components, and the unit is assembled and tested without any outside cover, but once the cover is installed, additional structural strength is obtained from the cover. A refrigerant flow sensor along with other sensors are used to determine actual real time cooling capacity measurements and health monitoring.

  • Patent number: 10933452
    Abstract: An anti-clogging liquid dispersion system and method for an air conditioner or heat pump is disclosed. A tank holds an anti-clogging liquid. A pump or valve connected with the tank periodically supplies the liquid to a condensate drain pan or the outlet of an existing drain line located exteriorly of a structure. One or more sensors are provided to detect moisture, flooding and/or lack of condensate flow and, when so detected, a control circuit causes the liquid to be supplied to the condensate drain pan to prevent flooding of a condensate drain pan or to clear a clogged drain line of an air handler of the air conditioner or heat pump. An additional dose of the liquid can also be supplied at any time when an unacceptable amount of condensate moisture and/or a clogged drain line has been detected.

  • Patent number: 10408493
    Abstract: A mounting pad system for securing equipment, such as an HVAC outdoor unit, is provided in the form of a lightweight fillable pad member having securing slots extending from an underside surface to an upperside surface of the pad member. Securing strap assemblies are associated with at least some of the securing slots and are insertable into the latter to secure the equipment therebetween. The pad member contains a filling port on its upper surface and is configured as a molded hollow shell containing a gelling material which, when mixed with water, provides support to reduce deflection of the pad member caused by the equipment secured to the pad, prevents damage to the pad that would otherwise be caused by the expansion of internal contents upon freezing and prevents leakage of internal contents of the fillable pad in the event of an unintended breach in the hollow shell.

  • Patent number: 10352865
    Abstract: A flow cell and method for photometric transmission measurements are disclosed in which a folded optical path provides for co-located, collinear fiber optic read and illumination cables that can be bundled together. Light passes through a fluid sample, is reflected off a pair of right-angle turning mirrors and returns through the fluid for a second pass. A center divider separates fluid passages on the first pass of the light through the fluid and the second pass of the light through the fluid to block any undesired backscattered light from reaching a detector.

  • Publication number: 20180220830
    Abstract: A pot support and method of use are disclosed for improving the efficiency at fuel-fired cookstoves. Heat transfer to a cooking vessel is improved by directing hot exhaust gases along the outer walls of a cooking vessel by providing a vertical lip at the outer edge of the pot support that lends to an improvement in cookstove thermal efficiency.
