US Patent:

43794483, Apr 12, 1983
Filed:

Feb 22, 1982
Appl. No.:

6/350564
Inventors:

Imants P. Kapralis - Hacienda Heights CA
Harry Krukle - Van Nuys CA
International Classification:

F24J 100
US Classification:

126263
Abstract:

A trigger to initiate crystallization of a supercoated salt solution comprises, (a) a thin strip having a perimeter, (b) said strip having a multiplicity of slits formed therein, each slit characterized as having opposed elongated edges which face one another in near touching relation, (c) the strip further characterized as having two configurations between which it is bendable with snap-displacement causing the slit edges to initiate progressive exothermic crystallization of said salt in the solution.

US Patent:

45805474, Apr 8, 1986
Filed:

Sep 17, 1984
Appl. No.:

6/651160
Inventors:

Imants P. Kapralis - Hacienda Heights CA
Harry Krukle - Van Nuys CA
International Classification:

F24J 100
F24J 300
US Classification:

126263
Abstract:

A heat producing apparatus includes a plastic container having flexible walls which are interconnected along a linear zone or zones; a supercooled salt solution is in the container, to be triggered and crystallized, to produce heat; and a trigger floats in the solution relative to the linear zone, and includes a bendable trigger strip, and a multiple member frame confining the strip, the frame and trigger movable together, relative to the linear zone or zones.
