  • Patent number: 10591195
    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.

  • Patent number: 10569343
    Abstract: An attachment retainer having a collar that, when at a collar locked position, has a first surface that is positioned above an open end of a passageway of a spindle to assist in retaining locking members in locking engagement with a driven tool. When in a collar release position, a second surface of the collar is positioned above the open end of the passageway to provide a space to receive a portion of the locking members so that the locking members can be disengaged from the driven tool. A plunger is displaceable to a position beneath another opening of the passageway to assist in retaining locking members in the passageway. A cam surface of a release ring can engage, and facilitate linear displacement of, release members as the release ring is rotated, which can facilitate axial displacement of the collar from the collar locked position to the collar release position.
