  • Fabricating bodies
    Patent number: 3992330
    Abstract: A method of manufacturing a body having channels extending through it and a body so formed. The method comprises the steps of working a single strip of material to provide corrugations the crests and valleys of which extend in a direction across the strip. The strip is then folded about an axis which lies at an angle to the crests of the corrugations in order to form layers each having the crests of the corrugations angled to, and lying across the crests of the corrugations of an adjacent layer or adjacent layers.

  • Pumps
    Patent number: RE29519
    Abstract: An axial piston pump is adapted to pump concrete or other slurries. On the suction side a wedge device is arranged to direct the concrete into or away from the cylinders according to whether the solid lumps are correctly placed for easy entry into the cylinders or likely to cause an obstruction at the downstream end of the suction side. A water barrier separates the concrete space from the oil filled drive mechanism and there is water lubrication of the working face of the cylinder block.
