    Patent number: 4133369
    Abstract: This invention relates to the making of negatives intended for the production of bodies which contain cavities of predetermined shapes.The term "negative" signifies a disposable core member, for example as used in some molding techniques such as the lost wax process. The negative at least partly matches the cavities which latter form two independent systems of regularly distributed intersecting channels with the channels in any one same system intercommunicating via ducts which are themselves regularly distributed.
