Abstract: A plunger lift system, as well as a method for monitoring plunger parameters within a wellbore using such a plunger lift system, are provided. The plunger lift system includes a lubricator attached to a wellhead at the surface and a plunger dimensioned to travel through the production tubing upon being released from the lubricator. The plunger lift system also includes magnetic sensor systems installed along the production tubing, where each magnetic sensor system includes a magnetic sensor for detecting the passage of the plunger as it travels through the production tubing, as well a communication device for transmitting communication signals between the magnetic sensor systems and a computing system located at the surface, where the computing system includes a processor and a non-transitory, computer-readable storage medium including computer-executable instructions that direct the processor to dynamically determine the plunger position and/or velocity based on the received communication signals.

Abstract: A tray denester for separating individual trays from a stack. The tray denester includes a product carrier plate that is movable toward and away from the discharge end of a product magazine. The product carrier plate includes a pair of air nozzle assemblies. As the product carrier plate moves toward the discharge end of the magazine, the air nozzle assemblies are activated to create a low-pressure zone along the product carrier plate. When the product carrier plate reaches the discharge end, an escapement mechanism releases the stack of trays. As the stack of trays is released, the low-pressure zone separates one of the trays from the stack. The separated tray contacts the product carrier plate and is removed from the stack. Each of the air nozzle assemblies is adjustable along the product carrier plate to vary the position of the air nozzle assemblies based upon the specific tray design.

Abstract: A balloon inflation device for use with a keyed balloon weight associated with a balloon to be filled with gas includes a source of pressurized gas sending gas through gas lines and multiple valves associated with an inflation block, wherein each valve is opened by properly manipulating elements of the inflation block. A key weight valve is opened by placing a key weight into a key weight receptacle in the inflation block, and a clamp valve is opened by manipulating a clamp mechanism. The key weight is associated with a balloon having a open neck that is placed over an inflation nozzle of the inflation block, before placing the key weight into the key weight receptacle. The clamp mechanism clamps the neck of the balloon to the inflation nozzle as it opens the clamp valve. With both valves open, gas may flow to the inflation nozzle to fill the balloon.

Abstract: The edge profile cutter includes a slidable base, a first cutting blade, and a second blade. The slidable base includes a base portion, an upright portion. The upright portion extends upward from a front of the base portion. A handle portion extends upward from the base portion at substantially a middle thereof. A first blade slot is formed in a bottom of the base to receive the first cutting blade. The first cutting blade may be adjusted within the first blade slot. Preferably, a first clamp slot is formed adjacent the first blade slot to receive a first clamp. The first clamp retains the first cutting blade. A second blade slot is formed in a front of the upright portion. The second cutting blade may be adjusted within the second blade slot. A second clamp preferably retains the second cutting blade. A lengthwise notch is formed in a front bottom edge of the base portion. The lengthwise notch may be sized to receive an end of a ceiling tile or the like.

Abstract: A balloon weight and ribbon assembly includes a spool having a length of ribbon wound thereabout, the ribbon being secured at one end to the spool and at the other end to a breakaway tab which initially comprises a part and parcel of the spool. A dimple in the tab accommodates receipt of a double knot at one end of the ribbon, while a slot in the spool accommodates receipt of a double knot of the ribbon at the opposite end. A piece of double backed adhesive tape is provided on the breakaway tab to allow for securement of the tab to the neck or tail of an inflated balloon.
