With a total of 3 patents to her name, her work has garnered attention for its innovative approaches and practical applications.

Latest Patents

One of Lillian's latest patents is a method and apparatus for processing semi-solid metal alloys. This invention includes a system for producing a semi-solid metal alloy from a molten charge. The apparatus features vertically aligned treatment zones created by a series of spirally wound flow pipes interspersed with induction coils. A container is mounted on a charging arrangement that displaces the first charge upward into the first treatment zone. Successive charges are introduced in a similar manner, urging the previously introduced charge upward along the treatment zones until the leading charge is ejected from the top of the apparatus. Each zone's charge is subjected to controlled cooling and an induced electromagnetic field, with the strength of the field and cooling rate carefully controlled to impede dendritic crystallization and promote globular primary crystal formation.
