20150040786 | VOLTAGE MONITORING FOR FIRESET - An improved fireset for detonating an explosive includes a voltage monitor arranged to measure a voltage across a quickly dischargeable energy storage device (QDESD), such as a capacitor, and to perform a detonation sequence based at least in part on the voltage measured by the voltage monitor. The fireset employs feedback from the voltage monitor to promote accurate charging of the QDESD and accurate maintenance of charge during an armed state. The voltage monitor also promotes safety by allowing the fireset to indicate when the QDESD is discharged to a safe level, i.e., one which is assured not to result in detonation. | 02-12-2015 |

20110168627 | MEMBRANE MODULE - The present invention relates to a method for curing adhesives used in the manufacture of membrane modules containing polymeric membranes, particularly polyimide based membranes used for the nanofiltration or ultrafiltration of solutes dissolved in organic solvents using microwaves. To maximise the chemical resistance of the adhesive used in these organic solvent applications, it must be as fully reacted and crosslinked (“cured”) as possible. Typically, thermal processing (heating) of the entire membrane module is used to cure the adhesives. However, the time and temperature required to achieve this high degree of completion of reaction may damage the separation performance of the membrane contained within the membrane module. In one particular aspect, this process utilises microwaves to preferentially promote the curing of epoxy adhesives over the general heating of the membrane module. | 07-14-2011 |
