Abstract: Self-grooming aid for animals, especially felines, whereby they can brush their fur or hair and can exercise or sharpen their claws. Such animal can stand at least partly on a base adapted to be clawed and with head or body at the level of a brush adapted to be rubbed. The brush is removable for cleaning or manually brushing the animal, and the mat is removable for replacement when thoroughly clawed.

Abstract: Sealing leaks in pressurized membranes, such as waterbeds without depressurizing. Such a membrane is gripped manually at the leak locus and vicinity, thereby folding and compressing the membrane to segregate and to seal the leak locus temporarily--and also enabling it to be dried. Next a patch is adhered over the leak locus, after which the membrane is released to return to its original shape. Apparatus for performing the steps subsequent to such manual gripping of the membrane include a base member and a first clamp member, pivoted together, between which the folded membrane is compressed; also a second clamp member, which--with the base member--compresses a patch onto the membrane, sealing off the leak locus permanently. The respective pivoted members are disengageably engageable, configured so as to maintain each such compression until completion of the desired steps, whereupon manual flexing disengages them from one another.
