  • Patent number: 5628239
    Abstract: An infusing unit is employed in a bubble-forming apparatus which includes a venturi-tube type inlet pipe unit, a discharge pipe unit, and a branch pipe. The infusing unit includes an infusing casing with a large-diameter upper section within which a main pipe section of the inlet pipe unit is press-fitted so as to establish a fluid-tight seal therebetween, and a small-diameter lower section located coaxially within the discharge pipe unit. A truncated conical lower end portion of the inlet pipe unit is located within the large-diameter upper section of the infusing casing and ranges from 1.0 mm to 1.7 mm in inner diameter. The infusing casing further has an integral tubular section which extends radially and outwardly from the lower section of the infusing casing and which is press-fitted into the branch pipe. The integral tubular section ranges from 2.5 mm to 3.5 mm in inner diameter.

  • Patent number: 4948945
    Abstract: An ironing device includes an iron body having an electric heating element, a seat on which the iron can rest when not in use and a power supply cord terminating in a connector having a socket adapted to connect with prongs on the iron body for supplying power to the heating element. The connector is provided with a first releasable latch for detachably interlocking the connector with the iron body so that the iron can be used as a corded iron and a second releasable latch for detachably interlocking the connector to the seat so that the iron can be used as a cordless iron. The user can selectively interlock the connector to either the iron body or the seat by activating a button device on the seat which selectively releases either the first or second latch.

  • Patent number: 4921640
    Abstract: A bubble-forming container has a venturi-tube type inlet unit which can rapidly draw a beverage into the body of the container. A blocking plate is disposed in the container body in alignment with the inlet of the container so that the liquid forming the beverage can pound against the blocking plate, thereby splashing to the inner wall of container body. A cylinder stands on the lower end wall of the container body. The liquid whirls around the cylinder and flows out of the container through an opening which is formed in the cylinder.
