Abstract: A top block for modular precast retaining wall system wherein beveled surfaces of a horizontal component of the top block form a cast-in-place key integrated with cast-in-place column formed in the construction of the retaining wall using modular block units. The top block provides an aesthetically pleasing front surface the upper edge of which may be rectilinear or contoured to fit various applications and appearance requirements.

Abstract: An improved banner holder and method for exchangeable signs, flags, and other banners with extreme structural simplicity and a minimum moving parts. The banner holder comprises a support, at least one mounting members, an interchangeable brace to hold the banner, and an apparatus to automatically reduce wind loads on the banner. The banner is mounted on a brace. The brace engages one or more unique mounting members in such fashion as to make the brace, and the banner mounted on it, easily mountable, removable, and replaceable. The apparatus further protects the banner and banner holder from wind damage by automatically reducing the effective area of a banner in response to wind loading.

Abstract: A novel and improved banner holder for displaying easily exchangeable signs, flags, and other banners with extreme structural simplicity and a minimum of moving parts. The banner holder comprises a support member, at least two mounting members, and an interchangeable brace adapted to hold the banner. The ends of the brace are adapted to engage the mounting members in such fashion as to make the brace, and the banner mounted on it, easily mountable, removable, and replaceable.

Abstract: This invention is directed to an apparatus to assist in retrieving tennis balls and in storing tennis balls. The apparatus comprises a bottom frame through which a tennis ball may pass upwardly when the bottom frame is positioned over the tennis ball and pressed firmly to the ground and which frame prevents the tennis ball passing downwardly and out of the frame by means of gravitational force. There is positioned above the frame a storage bag for storing tennis balls.
