Abstract: The ADL system provides a way in which computer programs written in different programming languages can share data. The ADL system comprises the ADL language and the facilities necessary to perform the data sharing function. The ADL language uses the concept of a data description and conversion module. A data description and conversion module, or more simply, an ADL module, is composed of declarations and plans. Each declaration is an ADL description of how a particular program environment represents data. The plan portion of the ADL module contains ADL statements that instruct the computer system to convert the data representations of the source program environment into the data representations of the target program environment.

Abstract: A marker sleeve assembly having a length of marker sleeves and a carrier configured such that the length of marker sleeves is oriented parallel to the carrier. The length of marker sleeves is held in a fixed, straight line adjoining the carrier, thereby reducing movement during the printing operation. Additionally, markings may be applied to both the length of marker sleeves and the carrier in a single printing operation.

Abstract: A portable fluid-mixing device. The fluid-mixing device comprises a container insert, an elongated shaft, a one-piece propeller, a wrench, a jam nut, and a crank. External threads of the insert are removably engageable with internal threads of an opening of a conventional 55-gallon drum. The propeller is pivotally connected to an end portion of the shaft. The wrench defines an annular surface and has external threads which are mated to internal threads of the insert. The jam nut defines an annular shoulder which is engageable by the wrench annular surface and has internal threads which are mated to the external threads of the insert, for bringing the insert into fluid-tight engagement with the drum opening. The crank, removably engageable with the shaft at the insert-carried end portion of the shaft, is used by an operator to manually rotate the propeller in the drum.
