Abstract: A system includes a plurality of thermostats corresponding to a plurality of HVAC systems that serve a plurality of spaces and a computing system communicable with the plurality of thermostats via a network. The computing system is configured to, for each space of the plurality of spaces, obtain a set of training data relating to thermal behavior of the space, identify a model of thermal behavior of the space based on the set of training data, perform a model predictive control process using the model of thermal behavior of the space to obtain a temperature setpoint for the space, and provide the temperature setpoint to the thermostat corresponding to the HVAC system serving the space. The plurality of thermostats are configured to control the plurality of HVAC systems in accordance with the temperature setpoints.

Abstract: A plastic bucket or pail has a receptacle portion unitarily formed with a grate portion and can be used to apply paint or other suitable materials to a roller. One can squeeze excess paint from the roller by rolling it over the grate. The bucket may be included as part of an integral product in which paint is provided in a sealed bucket.

Abstract: A boat loading device including a first frame secured to a vehicle supporting a second frame selectively extendable to a launch/retrieve position and retractable to a carry position. The device is usable upon a truck or trailer and can be used to carry objects other than boats. The device is easily removed from the vehicle and includes safety devices preventing accidental launch.

Abstract: An electrical control circuit which provides means of initiating the start of upset of a flash welding machine at an operator selectable value of flashing electrical energy. The energy signal for this circuit is taken from an energy monitor, such as the output of the circuit shown in U.S. Pat. No. 4,084,075. The control circuit, by means of a single adjustment of electrical switch means, may include a few additional electrical components to enable initiation of the start of upset, or termination of upset, as a function of platen position rather than as a function of flashing energy. Further, by simple adjustment of additional electrical switch means, further electrical components may be included to control the distance the movable platen moves during the upset portion of the welding cycle. Also, a meter may be included in the circuit to display either upset distance or upset initiation.
