Abstract: A shaft sealing arrangement for sealing bores around a pair of stirrer shafts that emerge through a wall of an associated mixing vessel includes a pair of generally cylindrical shaft sealing assemblies designed to be carried on adjacent stirrer shafts, each gland assembly including the gland member and a gland housing. A plurality of raised spaced radially distributed wiper strips are attached to outside surface of each gland which are directionally deployed at an angle with the direction of the axis of the gland such that the wiper strips act to return escaping material back into an associated mixing vessel. The gland assemblies are designed to be mounted on to rotate with a corresponding one of the pair of stirrer shafts and are enabled to move axially relative therealong.

Abstract: A low cost manual container lifting and placement unit operable by two people is disclosed which allows clamping, lifting and release of containers in a simple manner. The unit is made in two clamp jaw halves and each is connected to a rod that extends out to form handles on each side. The halves are connected by linking plates which allow rotation between the two halves causing the clamp halves to converge to grip a container of interest and diverge to release the container.
