Abstract: A secondary battery is provided for cycling between a charged and a discharged state, the secondary battery including a battery enclosure, an electrode assembly, carrier ions, a non-aqueous liquid electrolyte within the battery enclosure, and a set of electrode constraints. The set of electrode constraints includes a primary constraint system having first and second primary growth constraints and at least one primary connecting member, the first and second primary growth constraints separated from each other in the longitudinal direction, wherein the primary constraint array restrains growth of the electrode assembly in the longitudinal direction such that any increase in the Feret diameter of the electrode assembly in the longitudinal direction over 20 consecutive cycles of the secondary battery is less than 20%.

Abstract: A pharyngeal suction device for use during cardiopulmonary resuscitation and trauma stabilization. A hollow wand is provided with peripheral recesses which act as safety vents when the wand is used without the safety tip. The safety tip is attached to the wand in either of two orientations and secured at the peripheral recesses. A safety tip outlines a hemispherical surface and defines three passages which communicate with the interior of the wand.

Abstract: A hand-held pulverizer has a grinding section and a flat, detachable collecting plate into which pulverized material falls as it is ground. The pulverized material may be transferred from the collecting plate to a relatively small jar by attaching the broad end of a funnel-like device to the collecting plate, attaching a relatively small jar to the narrow end of the funnel, and inverting the funnel. When all of the material is transferred to the jar, the funnel may be removed, and a cap attached to the jar.

Abstract: A hand-held pulverizer which is compact and efficient to use is provided to pulverize or grind a material. A cover is removably attached to a hollow cylindrical casing containing a mesh screen. A grinder disc is securely affixed to one end of a shaft rotatably mounted in the cover and is in frictional contact with the mesh screen. A handle attached to the shaft above the cover permits the shaft and disc to be rotated, grinding or pulverizing the material placed on the screen beneath the disc. A collecting plate attached to the bottom of the cylindrical casing receives the pulverized material falling through the screen.

Abstract: A lightweight portable pocket size scale, the balancing mechanism of which may be folded and contained in the bottom portion of a two piece case when not in use and which may accurately weigh small quantities of substances when the cover portion of the case is removed and the balancing mechanism is unfolded from its storage position in the bottom portion of the case.
