Abstract: Substantially cylindrical and relatively thin-walled large volume containers such as silos are interiorly supported by means of a supporting structure in the form of a triangular supporting triangle, which is fixedly joined to the inner container wall. Thereby an essential amount of radial loads is converted into loads working in circumferential direction, i.e., working tangentially on the container wall, so that the risk of deformations is reduced when the load transmitting members such as pipes provided inside the container are joined to the supporting structure.

Abstract: A unique supplemental carburetion device for internal combustion engines producing a primary source of fuel-air mixture for use at idle and low engine speeds resulting in decreased fuel consumption and exhaust emissions comprising a fuel reservoir chamber joined to a source of liquid fuel and determinate fluid communication with a fuel metering chamber. The metering chamber preferably is vented to ambient air pressure contains diaphragm valve means for controlling fluid flow into the metering chamber. Liquid fuel from the metering chamber flows into a nebulizing chamber and is nebulized by interaction with a stream of ambient air or blow-by gases. The fuel-air stream is passed into a venturi throat and vaporized and then passed into an expansion chamber where the stream is expanded under low static gas pressure to a mixture having a pre-determined fuel to air ratio. The mixture exits the device and is delivered into downstream portions of the carburetor throat.

Abstract: An improved, non-occluding high fluid flow enteral feeding tube including a non-collapsible bolus carried on a distal end of the tube. The bolus having at least one opening defining a tube outlet. The one opening being defined by generally vertical bolus side walls having a selected transverse sectional height ranging from a height equal to at least one-half the inner diameter of the tube to no more than a height equal to the sum of the tube inner diameter and the thickness of the tube wall. The bolus further including an upwardly inclining internal bolus floor to gradually direct fluid from the tube, through the bolus and out of the opening minimizing disturbance of fluid flow rate.
