A tubing injector apparatus for use with variable diameter tubing. The apparatus comprises a pair of carriages which may be moved transversely and pivotally with respect to one another by actuating hydraulic actuator cylinders. A hydraulic control system uses relief valves to maintain a substantially constant pressure in the actuator cylinders when a tapered connector in the tubing passes between the carriages. A gripper chain in each carriage has gripper blocks to grippingly engage the tubing. A linear beam supports the gripper chain and has a plurality of resiliently biased segments therein to help maintain better contact with the tubing when the tapered connector passes through.

Tubing injector for variable diameter tubing

An additive material storage and metering system includes a transportable frame having a plurality of dry material storage bins mounted thereon. The plurality of dry material storage bins includes smaller dry material storage bins and larger dry material storage bins. The metering system for the larger dry material storage bins has a flow rate range varying from a low end to a high end. The metering system for the smaller dry material storage bins has a second flow rate range varying from a low end to a high end. The low end of the second range is lower than the low end of the first range, and the high end of the second range is between the low and high ends of the first range, so that any given dry material may be dispensed at any rate within an overall flow rate range from the low end of the second range to the high end of the first range by placing said material in the proper dry material storage bin. The dry material storage bins are partially supported from the transportable frame by load cells which are mounted on an extendable hydraulic cylinder so that the load cells may be withdrawn from engagement with the storage bin when the transportable frame is being moved, and may be extended into load supporting engagement with the storage bin when transportable frame is at rest.

Additive material metering system with weighing means

A transportable frame includes a plurality of liquid material storage tanks and dry material storage bins mounted thereon. There are smaller liquid material storage tanks and larger liquid material storage tanks. The metering system for the larger liquid material storage tanks has a flow rate range varying from a low end to a high end. The metering system for the smaller liquid material storage tanks has a second flow rate range varying from a low end to a high end. The low end of the second range is lower than the low end of the first range, and the high end of the second range is between the low and high ends of the first range. There are also larger and smaller dry material storage bins with similarly sized metering systems for the dry material storage bins. The dry material storage bins are partially supported from the transportable frame by load cells which are mounted on extendable hydraulic cylinders. The system also includes apparatus for controlling the storage and metering of the additives within the tanks and bins. This apparatus includes an element which determines how much additive is being discharged from an additive storage tank and an element for sensing how much of a primary substance is being discharged from a primary substance container. Based on the operation of these two elements, a third element controls the amount of additive discharged. This third element includes a microprocessor which controls the metering based on inputs from load cells, flowmeters, and manual data entry members of which the additive determining and primary substance sensing elements and the control element are comprised.
