Abstract: A system and a device are provided for counterbalancing a surgical robotic system that include a rail assembly having a shaft that engages a first carriage and a second carriage via threaded mechanism. A manipulatable arm carries a movable effector; the manipulatable arm is supported by the first carriage. A counter weight is supported by the second carriage with a single actuator. A simplified robotic surgery system results.

Abstract: A safety system and method for objects moved by a driving cabling system. Offers a redundant back-up system that activates when the main cable system fails. The safety system has various embodiments and may be utilized with camera movement systems configured to move the camera throughout two or three-dimensional space.

Abstract: A bucket dump block, used on dragline buckets, has side frames and a rotatable rope-guiding sheave. In the improvement, each side frame has a separate ring-like support section extending toward the other side frame and abutting the support section of such other side frame. The sheave is supported by and rotates about such support sections. The sheave rides on an annular anti-friction member retained on a sleeve into which the support sections are press-fitted. The dump block (which is devoid of provisions for lubrication) has a minimum number of parts and is easy to manufacture and repair.

Abstract: A load handling vehicle for movement of a load such as a drag of logs over rough terrain. The vehicle has a grapple assembly for lifting one end of a load for dragging the load over the terrain with one end elevated. The grapple assembly is connected to the boom of the skidder vehicle by a releasable load coupling. The grapple assembly is hydraulically actuated and hydraulically connected to the tow vehicle for that purpose. A mainline is connected at one end to the grapple assembly and at the other end to the tow vehicle and engages a powered winch drum permitting playing out and allowing for reeling in of the mainline. The grapple assembly is detachable from the tow vehicle by disconnecting the load coupling. When the grapple assembly is detached from the tow vehicle, it still engages the load and can be dragged by the tow vehicle using the mainline over the rough terrain.

Abstract: An apparatus for cleaning a tank-like vessel comprising(a) a supporting arm attached to a fixing plate, which can perpendicularly extend downward,(b) a folding arm of which base portion is rotatably attached to the lower end of the supporting arm, a position of the folding arm being changeable between a housed position and a position in use wherein the folding arm is approximately horizontally stretched out,(c) a rope winded up and winded down by a hoist, and(d) a cleaning nozzle capable of injecting jet water in a two-dimensional direction or three-dimensional direction.

Abstract: This invention relates to hoisting and traversing apparatus, and particularly to automatic hoisting and traversing apparatus which requires only a single motor for both hoisting and traversing. More particularly, the invention relates to a hoisting and traversing system in which the cable or chain which lifts the load can also be used to control the traversing movements of the load.
