A power bucket having a first and second bucket half pivotally secured together about a main axis by a pivot pin. The bucket halves are movable between an open and a closed position. A head is disposed above the bucket halves and at least one arm pivotally connects the head to one bucket half while at least one second arm is pivotally connected between the head and the other bucket half. A cylinder support is pivotally mounted to the pivot pin and one end of a hydraulic cylinder is attached to the pivot support. The other end of the cylinder is attached to the bucket. Upon actuation of the cylinders, the cylinders move the bucket halves so that a cutting edge of the bucket half moves in a substantially horizontal plane.

A clamp assembly comprising a pair of clamps may couple to an assembly body. The clamps may pivot to receive material beneath the assembly body. The clamps may include opposing surfaces that define a scoop space beneath the assembly body. Each of the clamps may include a cutting plate. The cutting plate may include a perforating edge configured to extend into the scoop space relative to a corresponding one of the opposing surfaces. The clamp may further include a retention plate. The retention plate may include an inner surface that faces the cutting plate. The cutting plate and the retention plate further define the scoop space between the clamps. The clamp assembly may couple to a lift assembly. The lift assembly may include a hydraulic actuator configured to raise and lower the clamp assembly.

Disclosed is a machine having a front frame and a rear frame connected by a hydraulic powered articulated steering, and mechanism for 360? rotation of a digger, a dumper, a jack and a cab. The machine is used for moving objects such as stones, cut stone or agricultural products such as bales of hay, and depositing them at another location which has a front frame and a rear frame connected by a hydraulic joint. The hydraulic joint is able to steer the machine and also move the front frame and the rear frame to move substantially smoothly over a rough or uneven terrain.

A feeding system for feeding animals, in particular cows, includes a feed storage system for keeping feed for the animals in store, and a feed loading device for loading a batch of feed from the feed storage system into a receptacle of an autonomous feeding device in order to teed the animals. The feed loading device is provided with a feed grabber including two grab buckets which are hingeable between an open position and a closed position. The feed grabber includes an actuation device for actuating the grab buckets from the open position to the closed position. The actuation device includes a rotatably drivable winding-up body which is connected to one of the grab buckets and includes a winding circumference, and an arm which is connected between the winding-up body and the other grab bucket. The arm includes a plurality of mutually, hingeably connected arm sections which are made from stainless steel or a material having substantially the same strength and corrosion-resistant properties as stainless steel. The arm sections, in the open position of the grab buckets, extend substantially in line with one another. The arm sections, from the open position of the grab buckets, when the winding-up body is rotatably driven, are wound about the winding circumference of the winding-up body in order to pull the grab buckets towards the closed position. The arm sections are configured in such a way that the winding circumference of the winding-up body can be covered substantially in its entirety by at most 8 arm sections, preferably at most 6 arm sections, in particular 2 or 3 or 4 or 5 arm sections.

Four cable operated scissors grab (1), comprising a pair of scissor levers (2a, 2b) that are connected via a pivot joint to pivot about a pivoting axis (4), which scissor levers each include a grab shell (5a, 5b) and a hoist cable connection (6a, 6b) situated on a first side of the lever with respect to the pivot joint, and a closing cable connection (8a, 8b) situated on a second side of the lever that is opposite with respect to the pivot joint, so that in use a dedicated hoisting cable is fastened to each lever on the first side of the lever, and a dedicated closing cable is fastened to each lever at the second side of the lever. The scissor levers each include a sheave (12a, 12b) on the second side of the lever, and said sheaves are each arranged as a first and final closing sheave, so that in use each of the two closing cables extend in a single pass from a closing cable connection on the second side of one lever via the closing sheave on the second side of the other lever to depart from the grab and continue upward to a crane carrying the grab.

Group online communication and collaboration has become part of people's daily life. Therefore, it is critical to provide a meeting initiator to efficiently present his/her information, and control his/her presented information. It is also critical for the speed and efficiently to process the meeting initiator's requests for his/her presented information to be quickly reaching to other meeting participants during a meeting. This invention facilitates a unique user interface (UI) for the meeting initiator to efficiently present information and to control presented information through a unique withdrawing (un-post) operation. Specially, this invention deploys dynamic workspaces technology together with post and un-post (withdraw) operations that greatly improves the speed and efficiency for processing the meeting initiator's requests and for monetizing the meeting activities.
