Abstract: This invention is a game and a head piece for the game. The game is played by any number of players who take alternate turns wearing the head piece which is a hat-like device, that supports a container of water. Positioned in the base of the container are a number of identical removable pegs. The removal of one particular peg will release the water down upon the wearer's head. All the pegs are identical so the wearer does not know just which peg will activate the water flow. The wearer is rewarded one point for each peg he has removed without getting wet. The game is played in a series of rounds wherein each player takes a turn wearing the hat-like device and a game is won after one player achieves a predetermined score. The game score is kept on a score mat upon which each player has a movable token.

Abstract: There is disclosed a stable thixotropic suspension of a fat in an aqueous liquid gel of a feed solution and a method for its preparation. The method comprises forming the liquid gel from a solution of sugar, protein or mixtures thereof, by incorporating ammonium phosphate in the solution in an amount sufficient to form the gel, adding water to reduce the concentration of the gel, and then adding fat. When fats with solidification temperatures above ambient temperature are added, the liquid gel is warmed to about the melting point of the fat and the fat is melted before mixing the fat with the liquid gel. Other water insoluble feed nutrients such as calcium carbonate, calcium sulfate, etc., or drugs such as monisan can also be suspended in the resultant gel. Water soluble feed nutrients such as urea, sodium bicarbonate, etc., can also be added.

The frangible keep member 6 is weakened locally so that it may be deliberately broken at that locality by manual force applied to it, whereby the bolt member 4 is moved out of its door-securing position by the spring 5.

Abstract: There is disclosed a water-base coating composition and method for its use that forms a readily strippable protective film on metal surfaces. The composition includes a film former ingredient which is a terpolymer of polyvinyl butyral, polyvinyl alcohol and polyvinyl acetate. The water-base coating composition also contains a fugitive corrosion inhibitor, i.e., a corrosion inhibitor having a sufficient vapor pressure to impart corrosion resistance to surfaces coated with the film former composition. Suitable corrosion inhibitors are aromatic triazoles such as benzotriazole. A leveling agent such as morpholine is used to prevent the film from pulling from the edges during drying. Morpholine is particularly advantageous as it extends the working time when coating objects, and prevents the dispersion from clogging nozzles of spraying equipment. Morpholine also contributes to the corrosion inhibition of the coating.
