Abstract: This invention is for a handle cover and toy holder for a shopping cart. The handle cover and toy holder is comprised of strip of washable fabric of a width sufficient to encompass a shopping cart handle and length sufficient to substantially cover the handle with closure members along both longitudinal sides of the strip along with a strap which is an integral part of the structure and serves the dual purpose of a toy holder and of holding the strip of fabric when folded.

Abstract: This invention relates to a device adapted to sensing motion when powered by passage of an electric current between two electrodes that is comprised of a container partially filled with an electrically conductive liquid along with two electrodes in contact with the conductive liquid at least one of which is only partially in contact with said conductive liquid. Motion of the liquid causes a change in resistance between the electrodes which may be detected as a change in current flow. These changes in current flow can be amplified and used to activate an alarm or other signal device.

Abstract: This invention relates to a method for improving the utilization of water-soluble, high molecular weight (molecular weight above about 1,000,000) polyelectrolytes in the dewatering of aqueous suspensions. By aging a mixture of the polyelectrolyte and water for a period of at least 6 hours to form an aged solution the amount of polyelectrolyte required to effectively dewater an aqueous suspension may be reduced to as little as 50% of the amount required when an unaged solution is used.
