Abstract: The present invention generally relates to processes for preparation of higher alcohols such as n-butanol from lower alcohols such as ethanol by Guerbet condensation. In some aspects, the present invention relates to improvements in n-butanol yield and selectivity by the selection of process reaction conditions such as, but not limited to, mole ratio of hydrogen to ethanol, mole ratio of acetaldehyde to ethanol, mole ratio of ethyl acetate to ethanol and/or mole ratio of carbon monoxide to ethanol.

Abstract: A safety device that would be installed within the fuel lines of motor vehicles including cars and trucks, with the device remotely activated by police and other law enforcement personnel to block the flow of fuel to the vehicle engine, thus disabling the vehicle to provide law enforcement officials a practical way in which to safely disable a motor vehicle in the event of a police chase, thus protecting both parties, as well as other motorists, innocent bystanders and property from the dangers that can easily occur as a result of high speed chases.

Abstract: A fuel-fired water heater is provided with a combustion chamber assembly, representatively a sealed combustion chamber assembly, operative to create from combustion air delivered thereto via a circumferentially limited vertical side portion thereof a flow of primary combustion air to the underside of a centrally disposed fuel burner within the assembly via a first location underlying the burner, a first flow of secondary combustion air delivered to the burner via the first location, and a second flow of secondary combustion air delivered to the burner via a second location outwardly circumscribing the first location.
