  • Publication number: 20090045074
    Abstract: An electrode for use in a deionization apparatus includes a conductive material that is in a granular form and is arranged in a layer that is defined by a first face and a second face. The electrode includes a substrate that is disposed against the first face, and a first member that is disposed against the second face and is formed to permit a fluid to pass through the first member and into contact with the granular conductive material to permit absorption of ions by the granular conductive material.

  • Patent number: 5681250
    Abstract: The present invention is directed to a combination chair and exercise apparatus. The combination chair and exercise apparatus is preferably comprised of a collapsible chair frame, mounted on a collapsible base, with rotation and pivoting points located on the frame and base so as to permit a user of the combination chair and exercise apparatus to bend the spine in either direction with respect to a lower portion of the user's body. In an alternative embodiment, the combination chair and exercise apparatus is non-collapsible. When not used for exercising, the combination chair and exercise apparatus may be used as a chair.

  • Patent number: 4818413
    Abstract: The copper corrosion rate is minimized to a certain discharge limit by providing a chlorine-bromide treatment in which the chemical feed rate of bromide is increased to an amount required to decrease the copper corrosion rate to the rate required to meet the discharge limit. The inventors made the unexpected and surprising discovery that an increase in the chemical feed rate of bromide--even when the chlorine feed rate is constant--has the effect of reducing copper corrosion. Therefore, this effect is useful for adjusting the copper corrosion rate to an optimum rate to most economically achieve a certain discharge limit.

  • Patent number: 4092024
    Abstract: An elongate support post is held in an upright position by the lower end thereof which is detachably received in a socket extending subterraneously from the surface of a game court. The support member has a channel at the top thereof which receives the uppermost rope of the net and conducts it to the other side of the member. A rope guide transmits the rope back through the support member to operatively adjustable straining means. Stop means carried by the support member abut the playing surface to provide a predetermined net height.
