  • Patent number: 3986708
    Abstract: The present disclosure is directed to a mobile batching plant having a primary frame carrying the cement storage, batching and weighing system and a plurality of rigidly connectable and detachable secondary modular frames connected in tandem each secondary modular frame carrying a combination batch and storage hopper having dispensing gates with an endless aggregate conveyor beneath the hopper gates. One sand and from one to three aggregate modules can be carried without affecting plant width. A fifth wheel for connection to a tractor is carried by the primary frame and a transport wheel assembly is connected to the last modular frame to render the entire plant transportable over the highway. The hoppers carried by the modular secondary frames are loadable by a small front end loader without the need of ramps because of their low profile.

  • Patent number: 3958639
    Abstract: The present disclosure is directed to a method of drilling an oil well so that the large diameter casing initially employed can be salvaged and reused which is attainable by effecting a temporary seal between the bore hole and casing so that a dual function is attained, firstly the seal forces the mud return up to the surface inside the casing and secondly the area between the bore hole and casing is closed to cuttings cement and other matter which may fall into a bore hole and cause the casing to become secured to the walls of the bore hole and prohibit the withdrawal of the casing from the bore hole. When it is desired to remove the casing the temporary seal is broken and the casing raised axially of the bore hole.

  • Patent number: 3955487
    Abstract: The present disclosure is directed to a wiener charcoal broiler employing a base block of a heat sink metal such as aluminum which cooperates with metal spaced wiener supports which receive their heat source from the heat sink base which protects the wiener from coming into direct contact with the heat (cooking) source and the wiener is cooked from heat conducted through the wiener supports which engage the wiener along its length and which cooking imparts a charcoal or barbecue taste to the wiener without burning or scorching a substantial portion of the outer surface of the wiener.

  • Patent number: 3945619
    Abstract: The present disclosure is directed to a continuous concrete proportioning plant of the mobile type movable from job site to job site not requiring extensive site preparation. The primary frame has a compact combination of cement sand and aggregate systems which permits sand and aggregate trucks to be backed onto a three sided hopper for each material which when charged is lifted and tilted toward the center of the machine where it feeds a belt conveyor running longitudinally toward the front of the machine. Each belt system contains a continuous belt weighing device and a totalizer will stop and/or clear the conveyor when a predetermined amount is attained. The sand and aggregate hoppers may be tilted to achieve the best flow rate through metering gates.

  • Patent number: 3941238
    Abstract: The present disclosure is directed to sanitary conveyor belts of polypropylene or other suitable plastic material having an integrally hinged construction defined by spaced notches which define the hinge points as well as drive engagement points between the belt and the sprockets having teeth which mate with the spaced notches. The belt construction also has one or more longitudinal notched grooves which defines a tracking and aligning groove which mates with a multi-faceted aligning member arranged polygonally about the perimeter of the sprockets which support the conveyor belt to preserve its alignment with the drive sprockets.The conveyor belt is used with an air levitation means in the form of a plenum chamber having openings to direct low pressure air against the underside of the belt to reduce friction drag when the belt is loaded.
