Abstract: A waste container comprising an opening, a permanent closure member, and an adhesive attached to the closure member for irreversibly sealing the closure member to another part of the container so as to, in use, permanently close the opening in the container.

Abstract: A method of calibrating an adaptive antenna array that applies beamsteering (1) of a satellite navigation system comprises receiving signals from a plurality of satellites at a plurality of receivers (2) within the system. The satellite direction relative to the antenna array orientation for each satellite signal is determined (5); and the received signals are despread (8) to recover satellite signals. Gain and phase information is calculated from the despread code for a given satellite in a given direction; and the calculated gain and phase information are stored in a manifold store (4) at a predetermined address related to the direction of arrival of the satellite signal.

Abstract: A device for forming chords on stringed instruments which have a fingerboard. A bar presses a plurality of strings on the fingerboard at a chosen position, a second member projects forward of the first bar and presses at least one string ahead of the first bar when the device is rotated about the first bar, a third member projects rearwardly and presses at least one string behind the first bar when the device is rotated in the opposite direction. There is at least one groove rearwardly of the first bar which, when the bar is rotated, a respective string is released from the bar.
