| 20090208320 | METHOD OF SEPARATING A NUMBER OF VIALS FROM A PLURALITY OF VIALS DISPOSED IN SEVERAL ROWS AND APPARATUS THEREFOR - A method of separating a number of vials from a plurality of vials disposed in several rows is disclosed. The vials being at first caused to move onto one transfer plane and being then caused to move further beyond the transfer plane in order for the vials intended to be separated to reach a surface adjoining the transfer plane, via the transfer plane, and that the remaining vials remain on the transfer plane. Providing a method of the type mentioned herein above, ensures that the vials are evacuated properly and completely without discrete vials toppling. This is achieved in that the vials still standing on the transfer plane adjacent the surface are next lifted or that the surface is lowered in order for the vials remaining on the transfer plane not to touch the surface. | 08-20-2009 |
| 20090232633 | CART FOR A TRAILER HITCH - A sturdy attractive cart with an upper portion, a lower portion, wheels, and steering suitable for both maneuvering while in a store, and on more rugged terrain. The cart may be carried suspended from a trailer hitch behind a motor vehicle. The cart has a vertical positioner to raise and lower the upper portion and lower portion relative to the other. The cart may be used as an off-road utility trailer, being towed by a vehicle. | 09-17-2009 |
| 20090304491 | Device and Process for Transferring Packaged Material to a Packaged Material Transport System or to a Storage Device - The device for transferring items to a transport system or to a storage unit has a feed unit for conveying a plurality of items in three parallel feeding lines. Further, is has a transfer station for receiving the items from the feed unit and for transferring the items to the transport system or to the storage device. The transfer station includes three temporary storage lines arranged in parallel. The items are provided by the feed unit in a manner that the items in each of the temporary storage lines are arranged offset from the items in the other temporary storage lines with respect to a first direction. A pusher in the transfer station pushes the items in a second direction perpendicular to the first direction to a single temporary storage line. | 12-10-2009 |
| 20100111665 | INTERNAL YAW DRIVE EXCHANGE FOR A WIND TURBINE TOWER - A method for removing and replacing an article of wind turbine equipment, such as a yaw drive, internal to a nacelle of a wind turbine tower without use of an external windfarm site crane or external rigging on the wind tower. External rigging of wind turbine tower components may expose workers and the equipment inside the nacelle to outside weather and hazardous wind conditions. The yaw drive is internally rigged with an internal support crane within the nacelle to an internal winch capable of supporting the yaw drive during a lift to the base of the wind turbine tower. | 05-06-2010 |
| 20110097187 | VEHICLE GUIDANCE SYSTEM FOR AUTOMOTIVE LIFTS - A vehicle lift system comprises a vehicle lift and one or more laser modules. The vehicle lift includes one or more lifting members that are operable to selectively raise and lower a vehicle. The laser modules are operable to emit at least one laser beam to provide a visual indicator on a vehicle positioned relative to the one or more lifting members. The vehicle lift may include any type of lift. The visual indicator may include a line, crosshairs, target, dot, or anything else, including combinations and patterns. The visual indicator may flash or remain solid. The visual indicator may be any color (e.g., green). One or more sensors may provide activation and/or de-activation of the laser modules in response to sensing the presence of a vehicle. An operator may view the visual indicator on the vehicle to confirm proper positioning of the vehicle relative to the lifting members. | 04-28-2011 |
| 20120201648 | METHOD AND DEVICE FOR BRINGING AN ELONGATED BODY BELONGING TO A SUBSEA STRUCTURE TO THE SURFACE - An elongated body belonging to a subsea structure may be moved to the surface. A lifting beam may be lowered to the body and then may be pivoted until the lifting beam is substantially parallel to the body. Grippers connected to the lifting beam may rotate to encircle the body and/or connect the body to the lifting beam. After the body has been released from the subsea structure, the body may be turned until the body is in a substantially upright position, and then the lifting beam may move the body through a splash zone to the surface. | 08-09-2012 |
| 20120207582 | Rock Grasping and Removal Apparatus - A manually deployed grasping apparatus may be utilized for retrieving objects, such as rocks, concrete chunks and other debris, from vertical excavations such as potholes, boreholes, drilled shafts, etc. Unlike backhoes and other articulated arm machinery, the disclosed grasping apparatus is manually lowered into the excavation by the user. Once the apparatus is adjacent to the object to be retrieved, the opposite facing jaw members of the apparatus are placed into an open position to receive the object. Once the object has been received by the opposite facing jaw members, the jaw members are closed to capture the object. The jaw members are then manually withdrawn from the vertical excavation to retrieve the object. | 08-16-2012 |
| 20130202400 | PALLET TRUCK ADAPTER - A pallet truck adapter having side by side shoes for fitting over pallet supporting tines, in which the shoes are of different heights. This facilitates locating one pallet on the higher shoe, lifting it slightly off of the supporting surface, and then moving to and lifting another pallet on the lower shoe. The adjacent pallets can then be moved together and off loaded at different locations, unloading the pallet on the lower shoe first, and the pallet on the higher shoe thereafter. | 08-08-2013 |
| 20150139773 | SYSTEM AND METHOD FOR TRANSPORTING TUBULAR ONTO A DRILLING RIG - A conveyor assembly for transporting tubular onto a drilling rig includes a plurality of conveyor sections coupled together end to end. The conveyor sections are configured to receive and transport the tubular. Each of the plurality of conveyor sections includes a conveyor belt having treads for transporting the tubular along the conveyor section. The conveyor assembly also includes an actuation assembly configured to transition the plurality of conveyor sections between a first orientation and a second orientation. The conveyor sections are not aligned in the first orientation, and the conveyor sections are substantially aligned in the second orientation. | 05-21-2015 |
| 20150367874 | DOLLY FOR MOVING OBJECTS - A dolly capable of allowing relatively heavy and bulky objects to be easily manipulated and moved without adding significantly to the dimension of the object thereby allowing the object to be easily moved through conventional door openings. Preferably, the dolly comprises a first frame having generally vertical legs mechanically coupled to a generally horizontal brace and a second frame having generally vertical legs mechanically coupled to a generally horizontal brace such that the first frame and the second frame are in position on opposite sides of the object and the generally horizontal braces are positioned under corresponding edges of the object. The generally vertical legs of the first frame and the second frame when moved into a more vertical orientation operate to mechanically lift the generally horizontal braces to lift the object and allow the object to be transported to a desired location. | 12-24-2015 |
