Video sharing is an important part of information exchanging between people in business and in daily personal life. Video sharing between two or more user devices through a server on the Internet usually will consume tremendous network bandwidth. With the supporting of posting and un-posting operations and the dynamic workspace technology introduced in this invention, a server here can centrally coordinate the dynamic secure video sharing between two or more devices while avoiding itself being a bottleneck for the video sharing.

A tilt adjustable head attachment assembly for a clamshell style bucket for orienting first and second bucket halves at an angle relative to a length axis extending through an elongated and rigid attachment associated with a piece of power equipment, for supporting and manipulating the bucket. A frame has a three dimensional body, upwardly extending pillar mounts located at upper ends of the body and incorporating support shafts for receiving overlapping hinged locations associated with support arms for each of the first and second clamshell bucket halves. A platen is positioned pivotally arranged between the pillar mounts and includes an upper location engaged by an end projection of the elongated attachment. A cylinder is connected to a fixed underside location of the frame at a first end and to the platen at a second end and, upon being actuated, pivotally displacing the platen to in turn angle the frame and supported clamshell bucket halves relative to the excavator attachment according to a desired orientation.

A dredging bucket having a head subassembly including an inner rotatable head and an outer head angularly supported by the inner head between level and tilted orientations. First and second opposing bucket halves supported by the outer head and pivotally actuating between closed and opened positions. A pair of T-links incorporated into spaced apart and coaxial pivot locations defined between the bucket halves, each of the T-links having a central stopping bar which, upon the bucket halves rotating to a maximum degree associated with the opened position, contacting end locations defined in upper edge profiles of the bucket halves in order to prevent further opening rotation.

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.

A system and method for handling slag in a slag pit includes an equilibrium or balance crane equipped with a quick connect coupling. A drop-ball fixture and drop-ball reduces the size of the slag, as needed, then the boom assembly of the crane releases the drop-ball fixture and engages an excavating tool, such as a clamshell bucket, a bucket, or a grapple. An elevated control station provides an operator with improved line-of-sight visibility.

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.
