Abstract
Abstract A tissue-embedding assembly is shown which is convertible to a resin option from a paraffin option. The tissue-embedding assembly permits the simultaneous embedding of multiple-tissue specimens with degassed embedding material. Full observation of the process as well as manipulation of the specimens is available during and up to solidification of the degassed embedding material. A novel heat transfer arrangement is available which permits the heating of paraffin to cause melting and embedding without disconnection of the refrigeration.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
A tissue dryer for drying and embedding tissue samples and the like comprising a cooling coil, support means including an axially extending sleeve disposed within and contiguous to said cooling coil, in direct heat transfer relationship with said cooling coil said support means being mounted on said cooling coil, and supporting container means and means to elevate the temperature thereof to permit heating of embedding material, a cassette mounted on said support means having a plurality of tissue receiving cups thereon, closure means enveloping said support means and cooling coil in a vacuumtight manner, and means to evacuate said closure means.
Claim 2
Dependent Claim
101 words
A tissue dryer for drying and embedding tissue samples and the like comprising a cooling coil, support means including an axially extending sleeve disposed within and contiguous to said cooling coil, in direct heat transfer relationship with said cooling coil said support means being mounted on said cooling coil, and supporting container means and means to elevate the temperature thereof to permit heating of embedding material, a cassette mounted on said support means having a plurality of tissue receiving cups thereon, closure means enveloping said support means and cooling coil in a vacuumtight manner, and means to evacuate said closure means.
Claim 3
Dependent Claim
108 words
A tissue dryer for drying and embedding tissue samples and the like comprising a cooling coil, support means disposed in heat transfer relationship with said cooling coil, a cassette mounted on said support means and having a plurality of tissue-receiving cups thereon, said support means including a reservoir, and each of said tissue receiving cups being perforated at its lower extremity to admit embedding material, said reservoir being filled with embedding material, and heating means to soften said embedding material to permit flow into said tissue receiving cups, closure means enveloping said support means and cooling coil in a vacuumtight manner, and means to evacuate said closure means.
Claim 4
Dependent Claim
108 words
A tissue dryer for drying and embedding tissue samples and the like comprising a cooling coil, support means disposed in heat transfer relationship with said cooling coil, a cassette mounted on said support means and having a plurality of tissue-receiving cups thereon, said support means including a reservoir, and each of said tissue receiving cups being perforated at its lower extremity to admit embedding material, said reservoir being filled with embedding material, and heating means to soften said embedding material to permit flow into said tissue receiving cups, closure means enveloping said support means and cooling coil in a vacuumtight manner, and means to evacuate said closure means.
Claim 5
Dependent Claim
89 words
A tissue dryer for drying and embedding tissue samples and the like comprising a cooling coil, support means disposed in heat transfer relationship with said cooling coil, a cassette mounted on said support means and having a plurality of tissue receiving cups thereon, said cooling coil being the sole support for said support means thereby to reduCe the mechanical vibrations transmitted to said cassette and said tissue receiving cups, closure means enveloping said support means and cooling coil in a vacuumtight manner, and means to evacuate said closure means.
Claim 6
Dependent Claim
89 words
A tissue dryer for drying and embedding tissue samples and the like comprising a cooling coil, support means disposed in heat transfer relationship with said cooling coil, a cassette mounted on said support means and having a plurality of tissue receiving cups thereon, said cooling coil being the sole support for said support means thereby to reduCe the mechanical vibrations transmitted to said cassette and said tissue receiving cups, closure means enveloping said support means and cooling coil in a vacuumtight manner, and means to evacuate said closure means.
Claim 7
Dependent Claim
88 words
A tissue dryer for drying and embedding tissue samples and the like comprising a cooling coil, support means disposed in heat transfer relationship with said cooling coil, a cassette mounted on said support means and having a plurality of tissue-receiving cups thereon, closure means enveloping said support means and cooling coil in a vacuumtight manner, and means to evacuate said closure means, said closure means including means to permit manipulation of the tissue in said tissue receiving cups during drying thereof without breaking the vacuum in said closure.
Claim 8
Dependent Claim
88 words
A tissue dryer for drying and embedding tissue samples and the like comprising a cooling coil, support means disposed in heat transfer relationship with said cooling coil, a cassette mounted on said support means and having a plurality of tissue-receiving cups thereon, closure means enveloping said support means and cooling coil in a vacuumtight manner, and means to evacuate said closure means, said closure means including means to permit manipulation of the tissue in said tissue receiving cups during drying thereof without breaking the vacuum in said closure.
Claim 9
Dependent Claim
29 words
The tissue dryer of claim 4 wherein said means to manipulate said tissue in said cup includes means to supply embedding resin under vacuum to each of said cups.
