Abstract: An injector system (1) for injecting liquid into a particulate material comprises an injector needle (10), a liquid supply tank (12) and a pump assembly (14). The pump assembly (14) includes a pneumatic cylinder (18) a liquid pump cylinder (20) and a piston (22) driven by a pneumatic drive arrangement. A controlled air supply (24) is provided with flow lines (28) (30) (32) for directing the air. An operator control valve (34) and operating button (36) is located on the injector needle 10. The injector needle 10 is inserted into a container containing a particulate material. In use, the operator control valve (34) is opened to allow air to operate the pump assembly (14) to cause liquid to enter the cylinder (20). The control valves (26) then switch over resulting in the liquid being fed along a feed line (50) towards the injector needle (10). The liquid exits through the injector needle into the particulate material. Once the liquid has been injected a full cycle has been completed and the injector system (1) may be used again by resetting the operating button (36) on the operator control valve (34).

Abstract: An explosives container, especially for ammonium nitrate-fuel oil explosives, comprises a plastics cylinder 1 having a domed end 2 for impact resistance and an opening 3 closed by a cap 5 which may be threaded. A hole 6 in the cap 5, or a puncturable membrane (12), allows for the addition of fuel oil to ammonium nitrate already in the container; the hole 6 is sealed by a grommet 7. Resilient fins 8 engage the borehole walls to prevent floating. A side groove (10) on the container acts as a channel for detonating fuse.
