Abstract: An improved drive mechanism for a reversible walk-behind soil compactor. The compactor includes a frame which carries a soil compacting plate and a drive mechanism, such as a gasoline engine is mounted on the frame and has a rotatable drive shaft. A pair of eccentrically weighted shafts are mounted for rotation on the frame and a belt drive connects each eccentric shaft with the drive shaft in a manner to rotate the eccentric shafts in opposite directions. Each belt drive is connected through a clutch to the drive shaft and the clutch is arranged such that each eccentric shaft is individually engaged with the drive shaft. Through manual operation of the clutch, the eccentric shafts are selectively rotated to thereby move the compactor in a forward or reverse direction over the soil to be compacted.

In particular, processes for the conversion of methylenic carbons to carbonyls, for the dioxygenation of aryl olefins, acetylenes and aryl-.alpha.-diols, for the oxidation of alcohols and aldehydes and for the removal of mercaptans from gaseous streams and for the removal of hydrogen sulfide and/or mercaptans from liquid streams are disclosed.

Abstract: This invention relates to drilling fluid additives that suppress clay swelling within a subterranean well and to methods for controlling clay swelling during the drilling of a subterranean well. Aliphatic polyamines and aliphatic acids react to form polyamides and polyamino acids that are water soluble, that have molecular weights of less than about 1000, and that have low toxicity levels. The polyamides and polyamino acids are added to water base drilling fluids which are circulated throughout a well.When X in the acid is a hydroxyl group, the polyamide products have the following general structure: ##STR1## When X in the acid is a halogen such as chlorine, the polyamino acid products have the following general structure: ##STR2## The drilling fluid additives and the method of controlling clay swelling provide for improved control of the rheological properties of drilling fluids along with an increased environmental compatibility.

Abstract: The drying section of a paper-making machine has a first drying group of a horizontal row of first drying cylinders which alternate with reversing rollers. A first upper web support belt wraps over the top of a first drying cylinder and then wraps the associated first reversing roller. An adjacent second drying group of a horizontal row of second drying cylinders which alternate with reversing rollers. A second lower web support belt wraps over the bottom side of a second drying cylinder and then wraps the associated second reversing roller. The drying cylinders and their reversing rollers are supported on two longitudinal beams which extend beneath the rows of drying cylinders. The drying cylinders of the second group lie at least at the same height above or higher above the longitudinal beams of the drying cylinders than the drying cylinders of the first group. The seocnd drying group is of a height to provide a clearance space over the floor and beneath lower support belt return path guiding rollers.

Abstract: The invention relates to a method and an apparatus for accurate digital determination of the time or phase position of a signal pulse train in relation to a fixed time or frequency reference. The arrangement generates and produces directly on the output a digital word corresponding to the measuring value current at that time. The pulse train is compared in a plurality of EXCLUSIVE-OR gates (OR0-OR3) with a number of reference clock signals (RCL0-RCL3) which are mutually displaced in time. There is produced on the output of each gate a signal (MS0-MS3) which is dependent on the input signals of the gates with respect to frequency and pulse ratio. The output signals from the gates are sent to a comparison circuit (CO) in which MIN of MAX operation is carried out, the pulse ratio of the output signals (MS0-MS3) being compared and the output signal which lies nearest to a predetermined pulse-ratio value being subjected to analogue/digital conversion in a converter (AD).
