A coating repair device for repairing a defect in a paint or coating by forming a repair patch around and over the defect. The repair device comprising a flexible member having an inner section peripherally surrounded by an outer section, each section having top and bottom surfaces with the bottom surface of the inner section being recessed with respect to the bottom surface of the outer section, such that when the flexible member is, in use, placed on the surface of a coating to be repaired it defines a cavity with the surface. An injection through-hole extends between a top and bottom surface of the device for the introduction of repair material into the cavity, in use, and one or more relief through-holes extend between the bottom and top surfaces of the device through which, in use, displaced air or surplus repair material may flow out of the cavity.
A coating thickness measuring instrument comprising: a magnetic induction probe comprising at least one drive coil and at least one pick-up coil; a driver for driving an alternating current in the or each drive coil; and a detector for detecting the output of the or each pick-up coil; and a processor configured to: apply a transfer function to the detector output to produce an output which corresponds to a measured coating thickness; and, scale both the drive current and detector output simultaneously in response to the output. The scaling may be changed in a step-wise manner. The scaling applied to the drive current may be inversely proportional to the scaling applied to the detector output. The scaling may be defined by a first and second scaling factor, stored as a pair. The instrument may store two or more pairs of scaling factors and select a pair in response to the measured coating thickness.

Control system for abrasive blasting apparatus and abrasive blasting apparatus
A control system for controlling abrasive blasting apparatus and an abrasive blasting apparatus including such a control system. The control system controls delivery of air and blast media to a blast nozzle of the abrasive blasting apparatus. The control system includes a deadman's switch, the deadman's switch features a user operable control. The user operable control is moveable from a first position, where the control system causes the abrasive blasting apparatus to not deliver air or blast media, to a second position where the control system causes the abrasive blasting apparatus to deliver both air and blast media. When the user operable control is in an intermediate position between the first and second positions, the control system causes the abrasive blasting apparatus to deliver air but not blast media. The control system may have control elements whose state may be sequentially changed by the user operable control as it moves.

Coating thickness measuring instrument and methods
A coating thickness measuring instrument has a probe for measuring the thickness of a coating applied to a substrate and producing an output relating to the measured thickness; a memory storing calibration data; and a processor arranged to process the output produced by the probe, together with calibration data stored by the memory, and produce a coating thickness measurement. The memory stores at least two sets of calibration data, each set associated with a different surface profile value and a user may select the set of calibration data to be used by the processor according to the surface profile of the substrate on which a measurement is to be made. This enables a user to make coating thickness measurements on substrates with at least two different, known, surface profiles without having to calibrate the instrument specifically for those surfaces.
