Abstract: A method of electrophoretic deposition of a ceramic green body. A ceramic powder is optionally washed with a polar solvent such as deionized water, dried, and suspended in a polar organic solvent in a proportion of at least 20% by weight. A positive surface charge is imposed on the suspended particles by conventional means such as ball milling or ultrasonic treatment. A green body is deposited on a cathode by passing a direct electric current of constant current density through the suspension. The density of the green body generally is at least 70% of theoretical. The density of the fired body generally is at least 98% of theoretical. A layered green body may be deposited by using several suspensions of differing global ceramic composition and depositing each microlayer in a different suspension.

Abstract: A sweepstakes promotion vehicle employs a description section containing graphics and text pertaining to the sweepstakes, a sweepstakes entry blank, a region containing a series of graphic descriptions of products, and a plurality of detachable product stamps. Each of the product stamps is detachably secured in proximity to the graphic description of the product associated with that stamp. The sweepstakes entry blank includes a game card having a plurality of spaces, each space adapted to receive a particular product stamp associated with the specific product. To complete the sweepstakes entry blank, a participant must detach the product stamps located contiguous to the product descriptions and affix the stamps in the appropriate space on the game card.
