Abstract: An egg shell removal device that comprises a handheld, oscillating assembly having a body member and an electrically driven attachment head. The head comprises a formed member driven by an oscillating output shaft from the body member, which provides a means to separate the shell and the inner and outer membranes from an egg white without damaging the egg white in the process. The head is a tapering section having a rounded tip, a concave interior surface, and a convex outer surface, whereby the interior surface travels along the egg white surface and contours thereto, while the outer surface lifts and breaks the shell as the head member oscillates from its oscillator or electric motor input. Also disclosed is an accompanying method of egg shell removal using a handheld, vibratory device to lift and break a shell from an egg white, which replaces traditional shell removal process conducted by hand.

Abstract: A combination of a chemical filter and a molecular sieve desiccant dryer are provided in the liquid line of the refrigeration system in a refrigerator which contains a chlorine-free hydrofluorocarbon refrigerant and a hygroscopic polyol ester compressor lubricant after a repair is made to the system and before it is recharged with fresh refrigerant. The chemical filter, such as activated alumina, filters out hydrolysis products of the lubricant and moisture which block the capillary tube, and the dryer removes moisture from system.
