    摘要： A novel process for production of polyethylene comprises polymerizing ethylene or a mixture of ethylene and a copolymerizable comonomer in the presence of a Ziegler-type catalyst at a pressure of 200 atm or more and at a temperature of 125.degree. C. or more, wherein an organic peroxide is added to the resulting polymerization product taken out of a reaction zone to deactivate the remaining catalyst. Formation of undesired oligomers or low-molecular polymers is prevented because the reaction does not proceed in the polymerization product taken out of the reaction zone. There is almost no retardation of the polymerization reaction even by the recycled use of the monomer separated and collected from the polymerization product.

    摘要： The present invention comprises a fuel pump controller having a silicon controlled rectifier (SCR) for supplying a power source voltage to a fuel pump circuit for driving a fuel pump when the SCR is turned on. A timer circuit is also provided for instantly turning on the SCR for a predetermined time period when an ignition switch is initially turned on so as to provide a discharge of fuel into the carburetor before the engine is activated or rotated. In addition, a controller is provided for repeatedly turning on the SCR each time the engine is rotated such that the fuel pump will be driven by rotation of the engine until such engine rotation ceases. By operation of this assembly, fuel is supplied to the carburetor for a predetermined time period before the engine begins to rotate so as to obtain an efficient and quick engine ignition despite the possible initial lack of fuel in the carburetor. Furthermore, since the SCR is thereafter operated by the ignition pulses generated from the engine rotation, the fuel pump will automatically shut off once the engine stops.

    摘要翻译： 本发明包括具有可控硅整流器（SCR）的燃料泵控制器，用于在SCR接通时将燃料泵电路提供给用于驱动燃料泵的燃料泵电路。 还提供了一个定时器电路，用于在点火开关最初接通时在预定时间段内立即打开SCR，以便在发动机启动或旋转之前提供燃料进入化油器。 另外，每当发动机旋转时，提供控制器用于反复地接通SCR，使得燃料泵将通过发动机的转动而被驱动，直到发动机转动停止。 通过该组件的操作，在发动机开始转动之前，燃料被提供给化油器一段预定的时间，以便尽可能地最初在化油器中缺少燃料以获得有效且快速的发动机点火。 此外，由于SCR之后由发动机旋转产生的点火脉冲进行操作，所以一旦发动机停止，燃料泵将自动关闭。
