  • Patent number: 7313840
    Abstract: An induction liquid pump includes a power unit and a circulation unit that are oppositely mountable to a tank with a plurality of fixation units. The liquid pump power unit includes a power induction unit to produce a variable magnetic field. The submersible liquid pump circulation unit includes an impeller unit to agitate or induce liquid flow in response to the variable magnetic field. A magnetic scrubber includes a power unit and a pad unit. The scrubber power unit produces a variable magnetic field in response to supplied power. When the scrubber power unit is held against a first surface of a tank, the scrubber pad unit is held oppositely against a second surface of the tank. The scrubber pad unit moves in response to the variable magnetic field to scrub the second surface of the tank.

  • Patent number: 5305483
    Abstract: The present invention solves a possible contributing cause of Sudden Infant Death syndrome. A body support pad having a support portion and a pillow portion is disclosed. The support portion is connected to the pillow portion. The pillow portion provides ventilation to the infant. The pillow portion has a thin outer sheet permeable to the passage of air which keeps the head of the infant in healthy repose. The interior of the pillow is subdivided into an upper portion containing a porous foam material and a lower portion containing an air pocket. An air pump supplies air to the air pocket to thus supply air to the nose and mouth of the infant.

  • Patent number: 5038530
    Abstract: A screened enclosure such as that commonly used to cover lanais, swimming pools, outdoor dining areas and the like has supports for overhead screening. Typically the supports are a series of roof arches joined by cross beams, and fixed screening is secured to the upper surfaces of these supports. The enclosure includes removable screen sections which are removably secured to under surfaces of these supports or the under surfaces of specially provided screen support members. These under surfaces to which the removable screen sections are removably secured define several perimeter sections which are usually but not always rectangular, with a separate removable screen section for each of those perimeter sections. When a removable screen section is removed, partially or completely, it is removed from underneath the screened enclosure so that no one has to climb above the screened enclosure to reach and remove debris.
