Abstract: A power unit is configured for use as part of a concrete screed and includes a frame and a powered drive. The frame includes a drive housing. The powered drive is operably supported by the drive housing and is configured to rotate a rotatable concrete forming drum. The powered drive includes an electric motor and a battery operably coupled to the electric motor and configured to power the electric motor. The powered drive includes a drive shaft drivingly connectable relative to the drum, with rotation of the drive shaft causing corresponding rotation of the drum.

Abstract: A beverage containing a natural colorant and one or more components of an Indian gooseberry extract and having sufficient color photostability is described. The active component in the Indian gooseberry extract is at least one of tannic acid, chebulinic acid, chebulagic acid, and phyllemblin. The natural colorant is a carotenoid and/or an anthocyanin. When the natural colorant is beta-carotene, it is preferably provided in a form of microemulsion. The beverage further contains a preservative, such as benzoic acid, sorbic acid, and a salt thereof. A method of formulating the beverage is also described.

Abstract: A power unit is configured for use as part of a concrete screed and includes a frame, a powered drive, and a drive coupler. The frame includes a drive housing and a handle to be grasped by a user, with the handle being configured to facilitate manual advancement of the concrete screed in the forward direction. The handle and the drive housing are pivotally attached relative to each other so that the handle is swingable relative to the drive housing about a pivot axis that is transverse to the forward direction. The powered drive is operably supported by the drive housing and includes a rotatable drive shaft. The drive coupler is attached to the drive shaft and is removably attachable to the connection shaft of a rotatable concrete forming drum so that rotation of the drive shaft is imparted to the connection shaft.

Abstract: A power unit is configured for use as part of a concrete screed and includes a frame, a powered drive, and a mechanical control connection. The frame includes a drive housing and a handle to be grasped by a user, with the handle being configured to facilitate manual advancement of the concrete screed in a forward direction. The handle includes a grip and a relatively shiftable user-operated drive controller. The powered drive is operably supported by the drive housing and is configured to rotate a rotatable concrete forming drum.

Abstract: A surgical instrument case which includes a primary case which is substantially rectangular and has a pair of opposite side walls, a pair of opposite end walls and a bottom wall. A secondary case fits within the primary case, and the secondary case has at least one attachment element on an outside surface of the secondary case. The at least one attachment element is configured for connecting to at least one of the side walls and the end walls when the secondary case is mounted on an outside of at least one of the opposite side walls and the opposite end walls.
