    • The present invention relates to processes for making polymers from at least one tertiary amino-containing monomer and at least one vinyl-functional monomer, while controlling residual monomers and avoiding production of Michael addition adducts. The process employs one or more of the following steps to avoid such adducts, maintaining at least one tertiary amino-containing monomer and at least one vinyl-functional monomer separate until the polymerization reaction, maintaining the at least one tertiary amino-containing monomer and at least one vinyl-functional monomer free of water until the polymerization reaction, and employing high temperatures for the polymerization reaction. The polymers are useful in personal care products, fabric detergent, hand dishwashing detergent, oil well treating chemicals, fire-fighting foam, agricultural chemicals, flocculants, coagulants, and household cleaners.

    • An apparatus for storing electrically generated heat includes a sealed container holding a bed of fusible heat storage medium, such as an alkali metal hydroxide composition, and having an expansion space above the bed of material to accommodate the medium in its liquid phase. A generally horizontal main electric heating unit is located in the bottom portion of the container for heating the fusible medium above its melting point. A first vertical electric heater is provided in the bed of material in thermal contact with the main heating unit and has its active heating portion extends upwardly from the main heating unit only to the height of the heat storage medium in solid phase. A second vertical electric heater is located in the container in thermal contact with the first vertical heater with the active heating portion of the second heater extending only from the height of the fusible medium in solid phase to the height of the medium in the expanded liquid phase. The main heating unit and first vertical heater are controlled by a control means responsive to the temperature in the vicinity of the main heating unit. The second vertical heater is independently controlled by a control responsive to the temperature in the upper part of the container. The main heating unit and vertical heaters each contain removable electric heating elements which can be repaired or replaced without drawing the heat storage medium from the container.
    • 用于储存电产生热量的装置包括一个密封容器,该容器容纳诸如碱金属氢氧化物组合物的易熔储热介质床,并且在材料床之上具有膨胀空间以容纳介质处于其液相。 大体上水平的主电加热单元位于容器的底部,用于在熔点以上加热熔融介质。 第一垂直电加热器设置在与主加热单元热接触的材料床中,并且其主动加热部分从主加热单元向上延伸到固相的储热介质的高度。 第二垂直电加热器位于容器中,与第一垂直加热器热接触,第二加热器的主动加热部分仅从固相的易熔介质的高度延伸至扩展液相中的介质的高度 。 主加热单元和第一立式加热器由响应主加热单元附近温度的控制装置控制。 第二垂直加热器由响应于容器上部的温度的控制单独控制。 主加热单元和垂直加热器各自包含可拆卸的电加热元件,其可以在不从容器中抽出储热介质的情况下进行修理或更换。

    • A flameless catalytic combustion apparatus includes a combustion chamber with a hydrogenous fuel inlet and a mass of catalyst in the chamber between the inlet and an outlet. Preferably the catalyst mass comprises porous pellet bodies supporting varying high and low concentrations of platinum family metals dispersed therein. For spontaneous starting of combustion the fuel is one of the lower alcohols and the high catalyst concentration is at the fuel inlet. The fuel may be in a container pressurized by air, or a lower ether or lower hydrocarbon which is also a fuel. Preferably separate, valved conduits from the fuel container first supply either atomized fuel droplets or air and fuel vapor to the high catalyst concentration for spontaneous ignition of combustion and vaporized fuel for continued combustion throughout the catalyst mass. The catalytic combustion apparatus may include a heat exchanger for fluids such as air, water or personal care foams and creams, or may be used in heating and cooking apparatus.
