Abstract: Offensive odors of animal origin are lessened or neutralized by application of deodorant compositions comprising 2,4-di (alkyl or aryl) substituted 6-hydroxy-1,3-dioxanes. The effectiveness of the compositions toward specific odors is increased by incorporation of acidic or basic components. The compositions can be further improved by the addition of other ingredients such as surfactants, chelating agents and antimicrobial agents.

Abstract: A coloring pen assembly comprising a tubular barrel open at one end and holding at the other end a porous nib having a marking tip, an extended portion lying within the barrel, and saturated with soluble coloring matter. For activation, a porous plug fitting loosely within the barrel and snugly around the extended portion of the nib is saturated with a liquid solvent, e.g. water, and is inserted through the open end of the barrel and pressed into place.

Abstract: A liquid manure pump which, without the use of valves, can alternately be used for agitating and mixing liquid manure in a pit and for discharging liquid manure from the pit into a tank or vehicle for transport. The impeller of the pump is ordinarily driven by an electric motor attached to the frame of the pump apparatus, and knives which are fastened to the hub of the impeller and rotate with the impeller blades stick through the inlet port of the impeller housing to cut up solids and, by virtue of their shape, to force-feed the pump.
