Abstract: Method for controlling defrosting of the outer exchanger of a heat pump machine, comprising the steps of: defining in the outer air temperature/evaporation temperature plane three zones; acquiring the outer air temperature and the evaporation temperature; individuating in which zone of the Taria_ext/T_evap plane the point falls, identified by the two acquired temperature measures; inverting the machine functioning cycle when the point falls in an unsafe zone; reducing the rotation speed of the compressor of said heat pump machine when the point falls in an intermediate zone.

Abstract: One embodiment of the present invention is a unique blower having an oil slinger system. Another embodiment is a unique rotor system having an oil slinger system. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for rotor systems, blowers and other apparatuses that employ oil slinger systems. Further embodiments, forms, features, aspects, benefits, and advantages of the present application will become apparent from the description and figures provided herewith.

Abstract: An oil slinger for a blower is provided. The oil slinger provides many unique features including, but not limited to, being removably mounted to a rotatably mounted shaft. Such removable mounting can be accomplished through use of an adapter sleeve mounted over a shaft, a slinger hub onto which is mounted an oil slinger, and a lock nut with retaining element. In one form the adapter sleeve includes a outer frustoconical surface which engages an inner frustoconical surface of the slinger hub.

Abstract: A merchandiser a case defining a product display area, and a lid disposed over the product display area and substantially enclosing at least a portion of the product display area. The lid is movable between an open position providing access to the product display area and a closed position limiting access to the product display area. The merchandiser also includes a handle assembly that has a handle coupled to and rotatable relative to the lid as the lid moves between the open position and the closed position.
