Abstract: A cannabinoid formulation comprising cannabinoid concentrate and beeswax, or a beeswax analogue, in a ratio of 30:1 to 40:1 by weight. Preferably the ratio is 35:1. The vaporizable formulation is packaged in a single use glass vial and used for pulmonary administration to a patient. The glass vial is made from borosilicate glass, has a cylindrical shape, an open end and no lid. The vial preferably has a uniform wall thickness of 0.02 inches. The formulation forms a wax seal at room temperature to eliminate any need for a lid. The formulation can be directly vaporized from the glass vial to eliminate transfer of the formulation to another container, to eliminate mess, to enable precise dosing, and to enable easy recycling and disposal of the vial after use.

Abstract: An alkaline cell is disclosed having a cathode comprising manganese dioxide wherein the cathode is a semisolid during discharge of the cell. The cell has an anode comprising zinc and an electrolyte comprising potassium hydroxide. The semisolid cathode comprising manganese dioxide may be in the form of a putty or paste. The semisolid cathode reduces cathode polarization effects and results in increased manganese dioxide utilization (Amp-hr/g), particularly at high current drain, between about 0.5 and 2 Amp. The porosity of the cathode is between about 45% and 70%, and the volume ratio of electrolyte solution in the cathode to the solids in the cathode is at a value between about 0.7 and 2.3.

Abstract: A current interrupt mechanism for electrochemical cells is disclosed. A thermally activated current interrupt mechanism is integrated into an end cap assembly for an electrochemical cell. The thermally responsive mechanism preferably includes a free floating bimetallic disk or shape memory alloy member which deforms when exposed to elevated temperature causing a break in an electrical pathway within the end cap assembly. This prevents current from flowing through the cell and effectively shuts down an operating cell. The thermally responsive mechanism may include a heat producing electrical resistance means, preferably a Zener diode, to enhance thermal sensitivity. The end cap assembly may include a pressure responsive mechanism which ruptures when there is extreme gas pressure buildup. Gas is allowed to escape from the cell interior to the external environment through a series of vent apertures within the end cap assembly.

Abstract: A current interrupt assembly for electrochemical cells is disclosed. The current interrupter assembly may be a self-contained, sealed unit which may be separately inserted into the cell during cell construction. Several current interrupt assemblies may be inserted in the cell. The current interrupter assembly has particular utility for thin rechargeable cells and when inserted in the cell forms a portion of the electrical pathway between a cell electrode and corresponding terminal. The current interrupt mechanism comprises a thin thermally responsive member preferably comprising a disk of a shape memory metal alloy having a curved surface. The current interrupt mechanism may include a heat producing electrical resistance means, preferably a Zener diode in proximity to the thermally responsive member. When cell temperature exceeds a predetermined value the disk deflects to cause a break in the electrical pathway within the assembly.
