  • Patent number: 8272536
    Abstract: The present invention provides improved retention of O-rings and easier O-ring replacement by using an O-ring retainer in a bar gun. Furthermore, the assembly of the butterfly plates of the bar gun is improved by using molded ball bearing clusters that fit in recesses in the butterfly plates, thus eliminating the welding of the balls to the butterfly plates and the need to purchase such precise and intricately small balls. The O-ring retainer and molded ball bearing cluster are preferably made from bearing quality acetal plastic materials.

  • Patent number: 5314090
    Abstract: An improved powder feeder having a hopper with an opening in its bottom. A resiliently deformable element is positioned in the opening of the hopper. The element has a flexible exterior dimension and is suitably positioned in relation to the opening to prevent the free flow of material through the opening. The element is mounted on an axle having an axis of rotation. The element is capable of carrying a metered volume of material through the opening as it is rotated. The axle is connected to a variable speed motor. As the element turns, the material flows into the element and moves through the hopper opening in precisely metered amounts relative to the volume and the speed of rotation of the element.

  • Patent number: 4810097
    Abstract: A dispensing apparatus is located in the rear of a tip truck body. When the tipping body of the truck is inclined gravity causes bulk material held in the tipping body at either side of a partition to feed augers. The dispensing apparatus includes at least one tank preferably a central tank holding powdered material such as cement powder dispensed through a chute by virtue of a paddle wheel dispenser. Water tanks which dispense water through an outlet are located at either side of the cement powder tank. A common drive shaft drives the augers and the paddle wheel. The dispensing of material is controlled by controllers such that a predetermined ratio of material can be dispensed into, for example a mixer. The dispenser can be used for dispensing the constituents of concrete and may be removable from the tip truck body so that the tip truck can function as a normal tip truck.

  • Patent number: 4759633
    Abstract: An apparatus for metering and mixing two different materials that are pasty or of low to high viscosity, includes a device for simultaneously delivering the materials from storage vessels to a mixing chamber, and a member for mixing the two materials in the mixing chamber, the mixing member and the mixing chamber, if necessary, being constructed as disposable items. The apparatus permits such materials to be mixed and metered with precision and has relatively few moving mechanical components, is of simple design, and even enables materials that react with each other to be mixed at room temperature without excessive heating during the mixing process. The device for delivering and metering the two mate includes screws mounted on a common drive shaft, provided with opposed stators and located in separate casings.

  • Patent number: 4444337
    Abstract: An apparatus and method for determining the heating value of gaseous fuels is disclosed which include the novel means for establishing a mixture of air and the gaseous fuel of interest in known volumetric proportions. An electrochemical sensor is provided to sense the products of combustion of the precise volumetric mixture and the output of the sensor is indicative of the relation of the mixture to a stoichiometric mixture of fuel and air. This system is provided for adjusting the proportions of fuel and air in the mixture of interest in response to the output of the electrochemical sensor until the sensor indicates that the mixture of known proportions is substantially stoichiometric. The system is provided for determining the heating value of the fuel from a known relationship between the heating value of the constituents of the fuel and the amount of oxygen required for stoichiometric combustion.

  • Patent number: 4121738
    Abstract: Apparatus for the continuous feeding of plural liquids in separate streams of adjustable quantity and ratio, comprises a drive unit that drives a main pump, and that also drives at least one secondary pump. The drive unit has an oscillating or reciprocating movement, and so the pumps are piston pumps or oscillating vane-type pumps. The stroke of the secondary pump or pumps may be selectively shortened without shortening that of the main pump, so as to predetermine the proportions of the liquids to each other. The system is particularly applicable for the feeding of separate streams of synthetic resins by the main pump, and the associated hardeners, catalysts, accelerators or other auxiliary liquids by the secondary pump or pumps.
