Title: Explosively actuated tools
Inventor: MCCULLOUGH DAVID JOHN
IPC: B25C1/12
Filed: 2004-06-23
Granted: 2009-10-20
Abstract: An explosively actuated tool for driving a fastener into a substrate is mountable to the end of a pole-like handle to permit manipulation and actuation of the tool from a remote position. Actuation of the tool occurs by pushing the forward end of a barrel of the tool against the substrate using the handle and then pushing forwardly the handle which loads and then releases a firing mechanism of the tool to fire the charge. The tool has a safety lock device for inhibiting loading of the firing mechanism sufficiently to initiate firing unless the tool is orientated upwardly into a vertical or near vertical orientation.

Granted: 2017-01-24
Abstract: The invention relates to a method for laying a playable surface such as a playing field, comprising the steps of forming a hard substrate, arranging on the hard substrate a layer of resilient and/or damping material, and arranging a top layer on the resilient and/or damping layer, wherein during or after arranging of the hard substrate and/or the resilient and/or damping layer air chambers are formed therein. The behaviour of the playing field becomes more natural due to these air chambers, and excessive resilience and energy restitution are avoided. The air chambers can be formed for instance by creating recesses in the relevant layer from the top, or by removing material from the layer at different locations after arranging thereof, for instance by melting or biological decomposition of inclusions. The invention also relates to a playing field obtain by application of this method.
