    摘要： A curing agent for epoxy resins, a process for curing the epoxy resins using the curing agent and curable or cross-linkable compositions comprising the curing agent and the epoxy resins are described. The curing agent comprises the reaction product of 4,4''-diaminodiphenylmethane and the glycidyl ester of ''''Versatic'''' acid (a mixture of saturated, highly branched, mainly tertiary monocarboxylic acids having C9, C10, C11, chain lengths). The curing agent and epoxy resin are intimately mixed together and allowed to cure at a temperature ranging from room temperature to a temperature up to 150*C. The reaction product or adduct used as the curing agent permits the use of a particularly successful curing agent, 4,4''-diaminodiphenylmethane which is normally too viscous and too slow to cure to be mixed with epoxy resins.

    摘要翻译： 环氧树脂用固化剂，使用固化剂固化环氧树脂的方法以及包含固化剂和环氧树脂的可固化或可交联组合物。 固化剂包括4,4'-二氨基二苯基甲烷与“Versatic”酸缩水甘油酯（饱和的，高度支化的，主要是具有C9，C10，C11，链长度的叔一元羧酸的混合物）的反应产物。 将固化剂和环氧树脂充分混合在一起，在室温至高达150℃的温度下固化。用作固化剂的反应产物或加合物允许使用特别成功的固化剂， 通常太粘稠且太慢不能固化以与环氧树脂混合的4,4'-二氨基二苯基甲烷。

    摘要： A blasting explosive cartridge comprising a substantially rigid tubular paper shell open at both ends, a thin-walled waterimpervious thermoplastic bag disposed in tight non-slipping relationship within said shell and a blasting explosive composition contained within said impervious bag, said bag being sealed at both ends and having an unfilled portion projecting outward one open end of said shell, the opposite open end of said shell having a heat-shrunk thermoplastic cap in closely adhering relationship thereover. Contrarily to cartridges of the prior art, the new cartridge is devoid of any gathering of paper at either end. This property has the advantage of assuring uninterrupted propagation of explosion in a train of cartridges placed end-to-end in a borehole.

    摘要： An apparatus for treating lignocellulosic material such as wood pulp with oxygen under pressure as a step in an oxygen bleaching process. The apparatus introduces the lignocellulosic material, oxygen and other reagents into the pressurized vessel continuously, and continuously withdraws the treated product and spent reagents. The apparatus permits the carrying out of a continuous oxygen bleaching process.

    摘要： A machine for attaching handles to components of carrying bags. The machine forms loop handles from a length of heat-sealable strip and heat-seals the ends of the handle loop to a rectilinear heat-sealable strip. The handle assembly so formed is available for heat-sealing to the open edge of a carrying bag. The rectilinear strip serves to attach the handle to the bag and to strengthen the open end of the bag.

    摘要： A bag-collecting device for use at the delivery end of a bagmaking machine comprising, in combination, two bag-collecting platens assembled in vertically spaced substantially parallel relationship, each of said platens having a front end and a rear end being coextensive with the other platen at its front end, and means for supporting the platens and reciprocatably moving at least the front ends of said platens between two vertically spaced positions whereby the two platens can be brought into alternative registration with the delivery end of the bagmaking machine, said means for reciprocatably moving the front end of the platens being automatically responsive to a bag counter unit.
