  • Patent number: 4117031
    Abstract: A condensation product obtained by first preparingA. an addition product of aliphatic aldehydes and phenol in a molar ratio of about 1 : 1 to 3 : 1, at temperatures in the range of from about 50.degree. to 80.degree. C, in the presence of an alkaline catalyst,And separately therefromB. a block polymer, obtained from a polypropylene glycol having a molecular weight from about 1500 to 2500 by the addition of about 30 to 50% by weight of ethylene oxide in the presence of an alkaline catalyst,And subsequentlyC. condensing about 0.5 to 4 moles of a) with 1 mole of b), after previous neutralization, if necessary in the presence of inert solvents, at 80.degree. to 150.degree. C, and removing the reaction water formed,And its use as demulsifying agent for the separation of water from crude oil emulsions.

  • Patent number: 4006946
    Abstract: A roller bearing for the shaft of a cement-mixer drum, universally jointed on a stub shaft of a planetary-gear train driving the drum shaft through a gear coupling with arcuate teeth, has an inner race fixed to the drum shaft and an outer race secured to a surrounding transmission housing, this outer race being axially split into two halves each accommodating a set of barrel-shaped rollers. The two sets of rollers are held in respective cages, peripherally offset from each other, and are engaged by toroidal inner surfaces of the two race halves curved about the center of rotation of the universal joint; these race halves extend axially beyond the end faces of the inner race to allow for a swing of more than .+-.3.degree. from a midposition. The outer cage diameter exceeds the smallest diameter of each race half.
