  • Patent number: 5069817
    Abstract: A process for the production of alkyl polyoxyethylenes showing improved low-temperature behavior, by reaction of alcohols with ethylene oxide at elevated temperature in the presence of basic alkali metal compounds as catalysts and subsequent neutralization of the alkaline catalyst with acids, which under prior art practice was impractical because of clogging of reaction vessels and equipment associated with precipitation of salts during neutralization, is made practical by adding a finely divided solid to serve as a precipitation control agent during neutralization. The finely divided solids used are, in particular, organic and/or inorganic materials known in the prior art as filter aids, such as kieselguhr and sawdust or other finely divided cellulose.

  • Patent number: 5031324
    Abstract: A power saw has two oppositely reciprocating saw blades guided and supported in a receiving slot in a support plate. The blades are supported during sawing along shoulders on their outside by lower edges of support sections of the support plate. The arrangement is such that forces generated in operation during cutting press the saw blades together in the area of their teeth. This prevents saw dust, chippings etc. penetrating between the two saw blades. Preferably, the thickness of the saw blade shoulders are not greater than half the thickness of the saw blades, and preferably no greater than the thickness of the support section edges. The teeth of the saw blades may be so ground and arranged that the resultant force on the teeth during cutting also forces the saw blades together at their teeth.
