  • Patent number: 11942851
    Abstract: A system for cooling a hermetic motor includes a motor cooling refrigerant flow path configured to direct refrigerant from a condenser disposed along a refrigerant loop to a hermetic motor, and from the hermetic motor back to the refrigerant loop, and a housing of the hermetic motor disposed along the motor cooling refrigerant flow path and configured to receive the refrigerant from the condenser, wherein the housing of the hermetic motor comprises an annulus surrounding at least a portion of a stator of the hermetic motor, and wherein the annulus comprises a plurality of openings configured to direct refrigerant toward the stator and into a cavity of the housing of the hermetic motor.

  • Patent number: 11655400
    Abstract: A hot-melt adhesive composition is disclosed. The hot melt adhesive comprises a) 25 to 95 wt %, preferably 50 to 85 wt % of at least one polyolefin-based polymer; b) 1 to 75 wt %, preferably 1 to 40 wt % of at least one tackifying resin; c) 0 to 15 wt % of at least one plasticizer; and d) 0 to 30 wt % of at least one additive and/or adjuvant selected from among stabilizers, adhesion promoters, fillers or pigments, waxes, and/or other polymers or combinations thereof, characterized in that the at least one polyolefin-based polymer is a mixture of: a1) at least one first polyolefin-based polymer with a molecular weight Mn of <10,000 g/mol in a quantity of 20 to 80 wt % with respect to the total quantity of polyolefin-based polymer, and a2) at least one second polyolefin-based polymer with a molecular weight Mn of >10,000 g/mol in a quantity of 20 to 80 wt % with respect to the total quantity of polyolefin-based polymer.

  • Publication number: 20220102091
    Abstract: Example aspects of the present disclosure are directed to an electrical switch with an adjustable tactile profile and/or an adjustable audio profile. One example includes an electrical switch with a pushbutton, a plunger, two metal contacts, a biasing spring, and a housing body. A user can press and move the pushbutton. The pushbutton's movement can move the plunger. The plunger's movement can cause the plunger to create or break a conductive connection between the metal contacts. Specifically, at least one unique actuator surface of two or more unique actuator surfaces on the plunger can engage the metal contacts. Changing the tactile profile can involve changing the unique actuator surface engaging the metal contacts. The conductive connection can indicate whether the electrical switch is in an unpressed or pressed state. The biasing spring can bias the electrical switch to the unpressed state. The housing body can contain the other components.
