Abstract: An article of insulation and a method for making same. Outer sheet-like elements (22,24) of elastic deformable material are secured by adhesive to a base element (20) of rigid deformable material in a particular pattern which defines unbonded areas which are each bounded entirely by adhesive. The combination of the two outer elements (22,24) and the base element (20) is then deformed, following which the base element (20) retains its deformed shape while the outer elements (22,24) spring back to their original shape, leaving voids between the base element (20) and the outer elements (22,24) in which there is a partial vacuum.

Abstract: A muscle powered liquid dispensing insert is provided for use with an implanted anchor having a hollow anchor sleeve extending into the subcutaneous fascia of a region behind an animal's ear. The insert includes one or more balloon-like reservoirs, each containing a drug or other medicant in substantially liquid form. Each reservoir means additionally provides effective means for anchoring the insert in the animal. A pump assembly draws the medicant(s) from the reservoir(s), and dispenses such to the animal. The pump assembly has a toroidal pump body defining a pump chamber and including a flexible impermeable pump diaphragm. The pump chamber communicates through inlet check valve means with each of the reservoirs, and through outlet check valve means with the tissue of the animal. The outlet check valve means operate at a higher activation pressure than the inlet check valve means. A piston powered solely by the animal's muscle and tissue operates the pump diaphragm.

Abstract: A liquid dispensing device particularly suitable for automatically dispensing a lubricant to the combustion zones of an internal combustion engine. A sealed lubricant reservoir conjoins with an air and liquid blending chamber formed by a housing. The housing is sealed save for a minute air bleed aperture. An inlet to the chamber for the liquid is provided in an upper part of the housing and an outlet from the chamber provided in a lower part of the housing.
