Abstract: A lock assembly comprising a throw bolt, a bolt holder and a bolt keeper. The bolt comprises a cutting barrier and a bolt casing, the bolt casing being more corrosion-resistant than the cutting barrier, and the cutting barrier being more abrasion-resistant that the bolt casing. When assembled, the cutting barrier will be enclosed within the bolt casing.

Abstract: A panel-post connector plate 16 for connecting a fence post 12 to an adjacent fence panel 14. The panel-post connector plate 16 comprises a plate body 84 having a post-receiving aperture 86 for receiving at least part of the fence post 12 therethrough, and a fastener receiving aperture 92 for receiving a fastener to attach the plate body 84 to a panel-body of the adjacent fence panel 14. A header-rail engagement member 94 is at or adjacent to the plate body 84, the header-rail engagement member 94 receivable in the header rail 26 of the adjacent fence panel 14. A temporary rail support device, a gravel-board retaining element, a fence post and a fence are also described.

Abstract: A lock assembly comprising a throw bolt, a bolt holder and a bolt keeper. The bolt keeper comprises a buffer and a biasing mechanism, configured such that when the lock assembly is arranged as in use, and the throw bolt is in the locking position, the buffer will space the throw bolt apart from a surface to which the bolt keeper is attached; and the biasing mechanism will bear on the bolt and bias it against the buffer.

Abstract: A fence-post system (10) comprising a first fence post (12) and a second fence post (14). The first and second fence posts (12, 14) are formed from folded sheets of metal of different thicknesses and have different front flange widths (FW1, FW2). A first fence post (12) has a wider front flange width (FW1) and a narrower thickness (T1) than the second fence post (14). The difference in material provided by the difference in the front flange width (FW1) equates or substantially equates to the difference in material provided by the thickness. Thus, the linear mass densities of the fence posts (12, 14) are similar or identical.

Abstract: The present disclosure relates to systems and methods for providing a virtual machine and for providing authentication of a user using the virtual machine. The disclosed systems and methods may perform operations including providing an application programming interface (API) to an electronic device; booting a virtual machine configured to emulate a type of electronic device based on a workstation to which the electronic device is connected; receiving input, using the API, from the electronic device; and providing output to the workstation using the virtual machine.

Abstract: A composition, suitable for use as an explosion suppression composition, and comprising a mixture of at least one particulate component selected from alkali metal bicarbonate, alkali metal sesquicarbonate, and alkali metal carbonate, and a free-flow additive in particulate form. Also, a discharge apparatus comprising a vessel containing the composition under pressure, and an explosion suppression system comprising a pressure change detector operatively connected to a discharge vessel.
