    摘要： This application relates to the use of alkyl alkanoates having molecular weights no greater than 74 as blowing agents in the production of flexible slabstock polyurethane foams. Compared to the blowing agents (fluorocarbons) widely used commercially in producing such foams, the alkyl alkanoates are more efficient in that they produce a greater volume of gas per pound of blowing agent.

    摘要： Disclosed is a primary dry cell, and particularly a magnesium cell, incorporating a fail-safe vent in the seal closure for the cell container, wherein the seal closure includes an annular insulating cover fitting tightly around the central carbon electrode rod forming a juncture therebetween which is tightly sealed except for a gas-venting passageway formed by complementary portions of the cover and carbon electrode rod. During normal operation of the cell, the gas-venting passageway is closed by a normally solid fusible sealant material. The sealant has a softening or melting point which substantially corresponds to some critical high internal cell temperature at which it is necessary to vent gas from inside the cell.

    摘要： Disclosed is a portable fluorescent lantern comprising two separate casings which are joined together in the normal portable mode of operation, one of which casings contains the main lantern parts including the fluorescent lamp, a lens and a reflector as well as the electrical circuit and related components for operating the lantern, and the other of which casings contains one or more high voltage batteries which serve as the DC power supply. The lantern may be operated with the two casings joined together or detached from one another with one of the casings being placed in a location remote from the other casing. An electrical cord is used for making electrical connection between the fluorescent lamp in one casing and the batteries in the other casing.
