Title: Wick insertion device for plant pot
Inventor: HOLTKAMP REINHOLD SR
IPC: A01G27/04
Filed: 1990-10-01
Abstract: Abstract of the Disclosure A self-locking wick insertion device for a pot to permit bottom watering of a potted plant by capillary action, the device including a base, a generally centrally positioned upwardly extending stem,   and  circumferentially  spaced,   radially extending ribs formed on the stem.    A groove is formed in the top of the stem for snugly receiving the wick, with a slot being formed in   the base through which the wick can extend into the water supply.  The ribs are inserted into an opening in the bottom of the pot, with the radial dimension of the ribs being such that the ribs   are slightly radially compressed during such insertion to provide firm frictional engagement of the ribs with the wall defining the opening.  The wick is maintained within the growing media for the plant, and water from the water supply can be transmitted by capillary action through the wick to the growing media.

Abstract: A power panel for use with wall panels of a space-divider system includes a lightweight frame structure having vertically extending end plates and a central web. Front and rear spaces are defined on either side of the web to accommodate electrical and communication wiring and receptacles on both the front and the back of the panel. A rib, extending from the web, divides the front and rear areas and provides physical separation between electrical power and communication wiring. The portion of the web on one side of the rib has an offset curved section to accommodate electrical wiring conduits extending vertically from the top to the bottom of the power panel. The power panel includes an upper area, with a removable cover, above the upper edge of the frame structure to accommodate wiring to and from, and between wall panels adjoining the power panel. A U-shaped cover is removably attached to the lower edge of the frame structure to accommodate wiring to and from, and between, panels adjoining the power panel. Snap-fit removable covers are attached to the front and back of the frame structure. The removable front and back covers and removable upper and lower covers provide easy access to the wiring in the power panel, which accommodates wiring in both the horizontal and vertical direction. The power panel accommodates receptacles on both the front and back in a back-to-back relationship, without increasing the thickness of the power panel beyond that of the standard wall panel, thereby providing an aesthetically pleasing arrangement.

IPC: E02D29/02
Filed: 1992-05-21
Abstract: ABSTRACT OF THE DISCLOSURE            A retaining wall and a block for constructing the same.   The retaining wall is constructed by superimposing rows of blocks upon each other.  The blocks have side, rear, front, top and bottom faces.  The side faces are parallel to each other and the rear and front faces are parallel to each other and perpendicular to the side faces.   The top and bottom faces are perpendicular to the side, rear and front faces; and both the top and bottom faces are substantially identically Z-shaped.  The top and bottom faces are divided into three surfaces, the second surfaces being inclined at an acute angle to the third surfaces.  The first surface of the top face is longer than the first surface of the bottom face.          Consequently, when the blocks are superimposed upon each other, the front face of each block lies slightly rearwardly with respect to the block immediately below it.  This results in the retaining wall being sloped backwardly towards the bank  of  earth,  the  angle  of  the  slope  corresponding substantially with the angle of inclination of the second surfaces of the top and bottom faces of the blocks.
