Abstract: A smart pad call up system enables connection of the electronic notepad or any communication device or multiple communication devices of the family members. The smart pad call up system updates every time when an item is placed on the smart pad call up system via handwritten entry with a stylus or keypad. The Smart pad call up system would have a voice command feature so that shopping list items is entered verbally in addition to stylus or keypad entry. This allows access to an updated grocery list to anyone with a communication device.

Abstract: A tapered polygon coupling for an impeller and shaft. The shaft has a tapered bore having a polygonal cross-section. The impeller includes a corresponding tapered polygon plug configured to be placed in the bore of the shaft. A fastener is provided for securing the impeller to the shaft. The fastener passes through a passage in the plug of the impeller. The plug of the impeller is split so that when the fastener is inserted into the passage the plug expands to contact the bore and create an interference fit between the shaft and the impeller. Additionally, the impeller may include the tapered bore having a polygonal cross-section, and the shaft may include the tapered polygon plug configured to be placed in the bore of the impeller.

Abstract: A tapered polygon coupling for an impeller and pinion. The pinion has a tapered bore having a polygonal cross-section. The impeller includes a corresponding tapered polygon plug configured to be placed in the bore of the pinion. A fastener is provided for securing the impeller to the pinion. The fastener passes through a passage in the plug of the impeller. The plug of the impeller is split so that when the fastener is inserted into the passage the plug expands to contact the bore and create an interference fit between the pinion and the impeller.

Abstract: A hydrogen generator employs substantially adiabatic hydrolysis and thermal decomposition of chemical hydrides to provide a controllable generation of hydrogen from a small, lightweight container. The hydrogen generator includes a thermally isolated container for containing a chemical hydride, a preheater to heat the chemical hydride to a predetermined temperature before the chemical hydride is hydrolyzed, a water supply controlled to maintain substantially adiabatic and controlled generation of hydrogen from said chemical hydride, and a buffer to supply an initial flow of hydrogen during generator start-up, absorb excess hydrogen during generator shut-down, and to smooth the hydrogen flow due to changing loads.
