Abstract: Sensor systems can be used to measure an analyte concentration. Sensor systems can include a base having a distal side configured to face towards a person's skin. An adhesive can couple the base to the skin. A transcutaneous analyte measurement sensor can be coupled to the base and can be located at least partially in the host. A transmitter can be coupled to the base and can transmit analyte measurement data to a remote device.

Abstract: A method of making on site a ground anchor having at least double corrosion protection about the anchor element, comprises locating a number of fixed lengths of corrosion proof sleeve about the element, applying a cap to the sleeve at the end of the element, and supplying a self-setting composition into the sleeve via the cap to fill an annular clearance between the sleeve and the element. The cap may be left in place on the end of the anchor to protect the anchor during insertion thereof into a borehole. The sleeve preferably comprises an outer plastics layer, an inner metal layer, and an intermediate layer of set filler.

Abstract: A method of anchoring an anchor element in a borehole comprises supplying self-setting composition into a sleeve while withdrawing the sleeve so that the self-setting composition fills the annular clearance between the element and the wall of the hole. Preferably the element is first secured within the hole by a self-setting resinous composition and, in order to provide additional corrosion protection for the element, the end portion of the element has a precast sleeve, and a plastics sheath is heat-shrunk on to the remaining portion of the element.

Abstract: A mobile production riveting system comprising a power actuated hand operated "gun" tool assembly for pulling and automatically collecting the mandrels of inserted blind rivets and panel mounted associated equipment including power supply, control valve, pressure regulator, vacuum transducer, mandrel retrieval system, hydraulic reservoir, and other support equipment for adapting a general factory air supply to power the hand tool under finger trigger control. Unusually fast cycle time results from a combination of improvement features including the limitation of vacuum venturi airflow for mandrel retrieval to a power-off portion of the cycle, the use of air pressure in lieu of a mechanical gun piston return spring, and a non-pumping system with respect to eliminating recycling of actuating hydraulic fluid to and from the hydraulic reservoir.
