Abstract: The invention relates to an HVAC apparatus, method, and system. Aspects of the invention include a supplemental heat source with an air handler unit for a conventional forced air heating and cooling system. The supplemental heat source in one example is a hydronic subsystem. It can be used alone or to supplement the forced air subsystem. Another aspect of the invention includes an air handling subsystem that has a housing that can be highly flexible in configuration and installation. The housing can support internal components, including a hydronic or other supplemental heat source with the forced air components. At least two sides of the housing can be configured for access for maintenance and repair. A control system can be designed to eliminate need for defrost cycle for forced air refrigeration-type subsystem and/or for better maintenance for comfort in the air conditioned space.

Abstract: A portable positive air filtration device including a respiration component and a harness component. The harness component being connected with the respiration component so as to secure the respiration component against the face of a user and covering the mouth and nostril of the user. One or more fans or air-moving components, one or more filters and at least one power supply provide filtered air to the user at a positive pressure. In some examples, the device includes a mask housing, a filter, a fan and an electronics control system. One or more batteries are provided for powering the device. The electronic control system can be connected with an electronic device for real time monitoring and control.

Abstract: A training and exercise device is provided to aid in proper positioning, technique, and muscle memory for different sports and exercise related activities. The training device includes a cylindrical barrel member. A sled or sleds are connected to the barrel member such that rotation and movement of the barrel member will in turn move the sled or sleds. The sleds are bi-directional such that they are able to move in both forward and rear directions, which will allow the training device to be used in multiple directions without having to reorient the entire device between exercises. The barrel device, sled or sleds may also be configured to adjust the weights thereof to increase or decrease the resistance of the movement of the training device to accommodate for different user's size, abilities, and intended outcome.

Abstract: This invention relates to a method of supplying desired quantities of heat, generated from selected inexpensive fuel burns in the firebox of a boiler, to an electric heat pump's refrigerant, while operating in its heating cycle. This supply of heat can be of sufficient quantities to satisfy the total ouput of the heat pump, minimizing its use of electricity, thereby creating a substantial savings, as the cost of the heat generated by the inexpensive fuel used by the boiler is much less than the cost of electricity.

Abstract: A method of curing green concrete using electric heating elements that are pulsed on and off by a programmable controller that controls a power source wired to an electric power main. A temperature probe may be used to inform the programmable computer of the concrete's temperature.

Abstract: The low temperature heat recovery system is used in combination with apparatus for drying a moving web of paper or the like and comprises a steam circuit, a gas circuit and a refrigerant circuit. The steam circuit recovers condensed steam from the rotary cylinders of the paper dryer, reheats the steam and injects the steam back into the rotary cylinders or back into the steam main. The gas circuit removes the wet air from the dryer housing, extracts the moisture and the latent heat from the air, reheats the air and injects the air back into the housing. The refrigerant circuit functions as a heat pump to heat the steam and air prior to injecting the steam and air into the cylinders and housing, and cools the air to condense and extract the moisture from the air.
