  • Metal-based microchannel heat exchangers made by molding replication and assembly
    Patent number: 9891006
    Abstract: Compression molding of metals is used to make microchannel heat exchangers. Heat transfer can be improved by employing controlled microchannel surface roughness. Flux-free bonding is achieved using a eutectic thin-film intermediate layer. Seals are leak-tight, mechanically strong, and uniform across multiple contact areas. The metal heat exchangers may be mass-produced inexpensively, and are useful for applications including the cooling of computer chips and other high-power electronic devices, air conditioning, refrigeration, condenser plates, radiators, fuel cell heat management, and instant water heating.

  • ORAL CARE IMPLEMENT
    Publication number: 20170150808
    Abstract: An oral care implement (100) in one embodiment includes an elongated body (101) comprising a head portion (110) supporting plurality of tooth cleaning elements (111) and a handle portion (120) defining an outer surface (127). A grip control component (130) is disposed on the handle portion (120) and includes a pair of transversely spaced apart control surfaces (132) separated by a longitudinally extending channel (133). The control surfaces (132) are elevated above the outer surface (127) of the handle portion (120) and positioned to engage a user's thumb. The control component (130) is operable to tilt the head portion (110) at an upward or downward angle relative to a vertical plane of a user's teeth when the control component (130) is grasped between the user's thumb and forefinger for producing a proper brushing angle at the gum line.
