Abstract
Abstract A molding kit to facilitate the synthetic cloning of body parts, such as fingers, the kit including a supply of alginate powder and a mold form having a bottom opening that is sealed when the form is seated on a base. A charge of powder is mixed with water to form a quick-setting, flowable molding compound. This is poured into the mold form, after which the body member is inserted and held therein until the compound sets to form an elastic gel. The gel is then pushed out of the mold form through the bottom opening, and the body part withdrawn to expose the impression cavity. The gel is returned to the mold form which is again seated and a flowable casting compound of the same composition as the molding compound is poured into the cavity and permitted the set to create a flesh-like clone of the body part. This clone is readily removable from the cavity without marring the impression therein.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A method of synthetically cloning a body part or other member to produce a replica thereof having flesh-like properties, the method comprising the steps of: A mixing a charge of alginate powder taken from a supply thereof with water to produce a quick-setting flowable molding compound; B pouring the molding compound into a mold form and inserting the part to be cloned therein to create an impression cavity: C holding the inserted part in the compound until it has gelled, the part then being removed to expose the impression cavity in the gelled mold; D mixing a charge of alginate powder taken from a supply thereof with water to produce a quick-setting casting compound; E pouring the casting compound into the cavity; and F after the casting compound has gelled to form the replica, removing it from the cavity.
Claim 2
Independent Claim
139 words
A method of synthetically cloning a body part or other member to produce a replica thereof having flesh-like properties, the method comprising the steps of: A mixing a charge of alginate powder taken from a supply thereof with water to produce a quick-setting flowable molding compound; B pouring the molding compound into a mold form and inserting the part to be cloned therein to create an impression cavity: C holding the inserted part in the compound until it has gelled, the part then being removed to expose the impression cavity in the gelled mold; D mixing a charge of alginate powder taken from a supply thereof with water to produce a quick-setting casting compound; E pouring the casting compound into the cavity; and F after the casting compound has gelled to form the replica, removing it from the cavity.
Claim 3
Dependent Claim
26 words
The method as set forth in claim 1 wherein the molding and casting compounds have the same composition, yet the replica is separable from the mold.
Claim 4
Dependent Claim
29 words
The method as set forth in claim 1, wherein said mixing steps are carried out in a mixing bowl having a spout to facilitate pouring of the resulting compound.
Claim 5
Dependent Claim
16 words
The method as set forth in claim 1, wherein said setting time is about two minutes.
Claim 6
Dependent Claim
26 words
The method as set forth in claim 1, wherein said part is a finger and said mold form is cylindrical and dimensioned to receive said finger.
Claim 7
Dependent Claim
39 words
The method as set forth in claim 5, wherein said mold form has a bottom opening which is sealed when the form is seated on a base, said opening facilitating the removal of the gelled mold from the form.
Claim 8
Dependent Claim
33 words
The method as set forth in claim 3, wherein said charge of alginate powder is measured by a measuring cup which has an extended handle usable to effect said mixing in said bowl.
