Abstract: A friction material has a plurality of connected sections and a plurality of oil localization slots. Each connected section is defined by adjacent oil localization slots in the friction material. The oil localization slot has opposing sides that define a reservoir which retains fluid in the oil localization slot when the friction material is formed into a desired shape on an end use product.

Abstract: An electrical heater is disclosed capable of producing dry, clean, heated compressed air having a housing with spaced apart end compartments and a heating unit mounted between the compartments. Regulated compressed air is caused to circulate through a plurality of chambers formed by tubes enclosing the heating unit where moisture is removed before it is passed to a filtered outlet. The moisture is collected in one of the compartments and automatically drained therefrom when the heater is not in use. A temperature responsive sensing element in the path of the circulating compressed air controls the degree of energization of the heating unit.

Abstract: An apparatus is disclosed for improving the efficiency and reducing the hydrocarbon exhaust emissions of combustion engines having a circulating water cooling system and a carburetor having a vacuum inlet port and a fuel inlet port and a fuel pump connected between the fuel inlet port and a fuel tank. In addition, a heat exchanger having a first tank is connected to the circulating water system to provide heat to a tube passing through the first tank and connected between the fuel tank and the fuel pump to expand the fuel in the tube. A second tank partially filled with water is in heat exchange relationship with the first tank and it has a pipe for introducing air into the water. An additional pipe is provided for connecting the unfilled part of the second tank to the vacuum inlet port of the carburetor for drawing air from the air pipe through the water when it absorbs moisture before transmission to the carburetor.
