Abstract: The present invention relates to methods, devices and systems for associating consumable data with an assay consumable used in a biological assay. Provided are assay systems and associated consumables, wherein the assay system adjusts one or more steps of an assay protocol based on consumable data specific for that consumable. Various types of consumable data are described, as well as methods of using such data in the conduct of an assay by an assay system. The present invention also relates to consumables (e.g., kits and reagent containers), software, data deployable bundles, computer-readable media, loading carts, instruments, systems, and methods, for performing automated biological assays.

Abstract: A non-expandible anchor for use in tensile zones of strong material having a compressive strength of at least 20 N/mm.sup.2 includes a cutting portion having a deep, coarse, raised, external helix formed with a cutting edge and having interruptions along the helix which act as chip breakers and permit removal of debris during insertion in a pre-prepared bore drilled in the strong material.

Abstract: A plastics pull-type blind fastener has a pull-part with a pulling stem and legs which pass through holes in a workpiece, shoulders of the legs engaging the workpiece at the blind side, and a push-part with a head to engage the workpiece at the accessible side and a plug extending between the legs to keep them apart after setting. The legs are accommodated in complementary shaped apertures in the head of the push-part, and at least one part has teeth to lock the parts together after setting, and allow removal of the pulling stem.
