Abstract: Disclosed is a device for transdermally detecting the concentration of one or more substances in a subject's bloodstream. The device includes a signal generation module arranged to generate microwave frequency signals at one or more discrete frequencies. The device also includes a sensor module comprising at least one microwave resonance sensor arranged to make contact with a subject's skin, the at least one microwave resonance sensor arranged to transmit microwave frequency signals generated by the signal generation module into the subject's body. The device also includes a signal processing module connected to the at least one microwave resonance sensor and arranged to: detect a resonance characteristic of the at least one microwave resonance sensor, and process the resonance characteristic to determine the concentration of one or more substances in a subject's bloodstream.

Abstract: A formwork system for use in slip form casting central cores of high rise buildings provides a rebate form for a rebate at the level of each floor slab which is subsequently to be cast. The rebate form is designed to carry ferrules to be cast into the core at the level of the rebate to provide anchoring points for incorporation of reinforcement associated with the floor slab. The ferrules are carried from the rebate form via plugs which are stripped from the ferrules after casting when the rebate form and main slip form to which it is attached is withdrawn.

Abstract: A support stand for a lifting anchor to be incorporated into a concrete component during casting thereof is formed from two identical components of bent wire assembled together to form an upper support frame and legs projecting downwardly from the frame. The two components are connected by only two welds, each at one of two zones of intersection of the two components.

Abstract: An anchor for embedment into a concrete component, has a head via which load is applied to the anchor in use and an anchoring formation provided by at least one leg extending from the head and profiled along an edge thereof so as to lock into the surrounding concrete. The profile is formed by a series of longitudinally spaced formations each of generally saw-toothed shape with a leading edge of each formation inclining towards the head such that on application of a pulling load to the head the leg will lock tighter into the concrete with increasing load. In one form the anchor is a lifting anchor and having a pair of such legs extending from the head which is adapted for releasable engagement with lifting equipment, and the profile is formed along an inner edge of each of the legs. In an alternative form the anchor is a plate anchor in which the head of the anchor is formed by a plate and a set of such legs extends from each of two opposite sides of the plate transversely to the plane of the plate.

Abstract: In a powder driven fastening tool, a channel is included for feeding a strip of explosive powder cartridges to a firing mechanism. A trigger is included for actuating the firing mechanism, wherein the trigger is movable between a first position and a second position. An advancing lever is pivotally coupled to the tool, the advancing lever having a strip engagement portion for indexing the strip which extends into the channel. An advance link is cammingly engaged with the advancing lever and is operationally associated with the trigger so that the strip engagement portion is in a first position in the channel when the trigger is in the first position and so the strip engagement portion is in a second position when the trigger is in the second position.
