  • Patent number: 7428956
    Abstract: An auger assembly transfers particulate material from a source area to a target area using a main auger, an intermediate swing auger and a loading swing auger connected in series with one another. The main auger is supported on a wheeled frame similar to conventional grain augers while the intermediate swing auger is pivotal thereon and the loading swing auger is pivotal on the intermediate swing auger. The inlet hopper of the auger assembly can thus be more easily positioned relative to the main auger for proper alignment with the discharge hopper of a particulate material container even when the discharge hopper is within a confined space.

  • Patent number: 7418913
    Abstract: A kit features two arm assemblies, each of which features a longitudinal member with a padded portion extending from proximate one end thereof toward the other end and a connection at each end allowing horizontal and pivotal motion of the arm assembly about. A method of mooring a watercraft involves connecting each arm assembly between a respective connection point on the watercraft and a respective securing point on a body distinct therefrom, allowing horizontal pivoting of the arms to horizontally move the watercraft toward a vertical plane in which the securing points lie and blocking further horizontal pivoting of the arms by contact between the watercraft and a respective one of the arm assemblies before the watercraft reaches the vertical plane. The arm assemblies bind due to contact with the watercraft, thereby blocking impact of the watercraft with the body to which the securing points are mounted.

  • Patent number: 7377051
    Abstract: A tubing counter for counting coiled tubing inserted into a well includes an outer housing having a through passage for receiving the coiled tubing therethrough. In some embodiments, pressure rated connectors at both of the ends of the outer housing sealably connect the outer housing in series between the coiled tubing injector head and the outer casing of the well. A plurality of counting wheels are rotatably supported within the outer housing for rolling engagement along coiled tubing inserted through the outer housing while a counting mechanism records a number of rotations of each counting wheel independently of the other wheels to minimize counting errors. Locating the counter below the injector head and below the tubing stripper ensures that the tubing is cleaner and less likely to slip in contact with the counting wheels while also accounting for stretching of the tubing for more accurate measurement.
