Abstract: The present invention provides a system of jointing and finishing plasterboard sheets. The system comprises adjacently abutted first and second plasterboard sheets and a connective material. The connective material is applied to a region at or near the side edge portions of the first and second plasterboard sheets and which securely joins the side edge portion of the first plasterboard sheet to the side edge portion of the second plasterboard sheet. There is also provided a joint filling compound and a finishing compound, which are optionally also applied to the region of the first and second plasterboard sheets.

Abstract: A laser-sighted firing device adapted to be carried in a portable enclosure, such as a briefcase, to conceal the device from detection. The device includes a firing piece and a laser-type sighting device mounted on a rigid base. The sighting device is adapted to project an aiming spot to a target along a sight line generally parallel to the line of fire of the firing piece. The sighting device is resiliently mounted on the base and means are provided for adjusting the device to calibrate the laser spot relative to the line of fire of the firing piece. The firing piece has a trigger mechanism that is operated by a lever pivotally mounted at one end on the base and connected at the other end to a solenoid-actuated operating means. The lever is operatively connected intermediate its ends to the trigger mechanism for firing the piece in response to actuation of the solenoid.
