Abstract: Compressed data objects are stored in a remote data store and are accessible to end users for data retrieval and processing. The remote data store is optimized for efficient data storage and retrieval with processes for capturing data profile statistics and creating an index of compressed data. Descriptive information about data objects and processing logic is displayed and made available for viewing and access by end users having a client application which manipulates the descriptive information to create a customized data retrieval and processing request. An end user can add descriptive information about its own data to the request and attach its own compressed data to the request that will be included in data retrieval and processing. Descriptive information representing data and logic stored in multiple remote data stores can be integrated into one request. The request can be submitted to several data stores in succession for automated data retrieval and processing without jeopardizing request security.

Abstract: A lower leg exercise device (1) has an upper panel (2) and a lower panel (3) which are hingedly attached together along opposing longitudinal sides. A pair of elliptical forming panels (8) are hingedly attached to the lower panel (3) and are each foldable between a first position in which they lie substantially flat against the lower panel, whereby the upper panel may be collapsed flat against the lower panel for compact storage, and a second position in which they engage between the first and second panels in an upstanding manner so as to maintain the panels in spaced apart relationship. In said second position, the loading applied by the convexly curved upper and lower edges of the forming panels (8) to the upper and lower panels (2, 3) results in said panels each adopting a convexly curved shape. In use, the device is placed on the floor in its erect configuration, the user placing their feet on the upper panel and rocking the device back and forth on the curved lower panel.

Abstract: A walkway system for roof, truss or elevated workers or the like is attached to a structure, e.g. a building wall of an unfinished building. The system utilizes first and second longitudinally spaced-apart support assemblies for releasable attachment to a top of a building wall. Each assembly presents a depending support bar extending along an exterior surface of a building wall. A horizontal support brace is attached to each depending support bar at selectable positions therealong, the horizontal support brace providing support for overlying boards of a walkway. Attached to the free end of the horizontal support brace is a vertical post having a plurality of vertically spaced-apart brackets thereon for receiving a portion of a plurality of vertically spaced-apart hand rails therein. A series of hook-like brackets are releasably placed along the rails for positioning a reinforcing strut adjacent each hand rail.

Abstract: The invention relates to a device for supporting and training plants and in particular for layering tomato plants. It comprises a longitudinal stem portion formed with an integral hook which is adapted to grip and slide along a support wire which is mounted above and parallel to the plant row, and a spool rotatable about a cylindrical bearing surface of the stem portion. The spool carries a support cord which passes upwardly from the spool, through an aperture in the top of the stem portion and down through the hollow interior of the stem portion to where it is tied to the stem of the tomato plant. When it is desired to layer the plant the stem portion is moved along the wire and simultaneously the spool is rotated to pay out sufficient cord to layer the plant. Rotation of the spool is controlled by means of ribs on a flange of the spool which engage with the horizontal support wire.
