20150377852 | APPARATUS AND METHOD FOR SURVEYING - An apparatus for surveying includes at least one survey cable, each survey cable having a proximal end attached to a mother vessel, a distal end connected to at least one subsurface towing vessel, and at least one survey device connected to the survey cable between the proximal end and the distal end. The survey cable extends in a direction perpendicular to a longitudinal axis of the mother vessel during a survey. The survey cables extend a distance E sideways from the mother vessel, for example under an ice cap, e.g. solid ice or ice floes. When surveying in a polar region, the mother vessel needs only to break a narrow channel in order to survey a large area, thus saving energy, time and money. | 12-31-2015 |

20130019533 | OVERHEAD DOOR ASSEMBLY WITH COUNTER BALANCE SYSTEM - A counter balance system for an overhead door assembly is provided. The overhead door assembly includes a door frame, an overhead door, and a door lifting assembly. The door lifting assembly includes an extension spring, a cable, and a pulley assembly. The pulley assembly guides the cable as the door is moved between a raised open position and a lowered closed position. A pulley of the pulley assembly is mounted so that an axis of rotation of the pulley remains perpendicular to a portion of the first cable extending between the pulley and a lower portion of the overhead door as the door is moved between the raised open position and the lowered closed position. | 01-24-2013 |
