  • Patent number: 10933433
    Abstract: A hand-held high-pressure cleaning machine includes: a housing, having a handle for grasping; functional components, including a motor and a pump driven by the motor; and a liquid inlet, disposed on the housing and capable of being connected to an external water source by a water pipe. The hand-held high-pressure cleaning machine further includes an adapter suitable to be connected between the liquid inlet and a portable container, and is connected to the external water source by the water pipe or connected to the portable container by the adapter. In the present invention, the portable container configured to hold liquid is mounted to the hand-held high-pressure cleaning machine by using the adapter, so that it can be flexibly moved together with the hand-held high-pressure cleaning machine. The present invention further provides an adapter suitable to be connected between a portable container and a hand-held spraying device.

  • Patent number: 5953331
    Abstract: A telecommunications system is arranged to efficiently route digital information from a mobile network to a Public Switched Telephone Network (PSTN) and vice versa by interposing a packet network between the mobile network and PSTN so that digital information originating from the wireless network at a first data rate may be forwarded over the packet network at that rate and then sent over a direct connection from the packet network to the PSTN at a second data rate expected by the PSTN. In this way the conversion of the digital information from the first to the second data rate is performed only when needed, i.e., at the ATM switch connected to the PSTN.
