A connecting means adapted to fix or release a first element (4) and a second element (5) includes a locking pin (1) which is moveable to remote activation means between a locked position. In which leg (8) expends wall (9) into recess (10), and an unlocked position. The remote activation means may be magnetic, electro-magnetic or any other suitable means. A method of fixing or releasing first and second elements by remote activation means is also disclosed. The invention further provides a first element having first means (166) adapted to cooperate with second means (165) on a second element to facilitate connection of the first and second elements. A method of manufacturing the first element includes the steps of depositing discrete amounts of setable material on a surface of the first element and inverting the element to permit the material to set under the influence of gravity. A method of reducing the spacing between first and second elements by remote activation means is also disclosed.

Apparatus and methods for combustion of fuel. Some embodiments of the inventions include a fuel nozzle which injects fuel into a combustion channel of a wave rotor combustor or a pulse detonation combustor In some embodiments the combustion process includes a backward-propagating detonation wave within a substantially closed channel which compresses discrete quantities of combustible and noncombustible mixture. Yet other embodiments include a precombustion chamber integrated into the wave rotor, the outlet stator or both.

A connecting means adapted to releasably fix or release a first element (4) and a second element (5) includes a locking pin (1) which is moveable by remote activation means between a locked position, in which leg (8) expands wall (9) into recess (10), and an unlocked position. The remote activation means may be magnetic, electromagnetic or any other suitable means. There is no permanent material connection between the pin (1) and the remote activation means. A method of fixing or releasing first and second elements by remote activation means is also disclosed. The invention further provides an embodiment where the first element is a first panel and the second element is a second panel. The first panel has means (166 or 169) which co-ordinate with means (165 or 170) on the second panel. A method of manufacturing the first element includes the steps of depositing discrete amounts of setable material on a surface of the first element and inverting the element to permit the material to set under the influence of gravity. A method of reducing the spacing between first and second elements by remote activation means is also disclosed.

A removable secondary liquid dispensing module for use with an existing, automated liquid handling system that defines a work area having a plurality of discrete work stations. Each of the work stations of the automated liquid handling system includes a lab ware site and alignment structure enabling the removable securing standardized microtiter-plates at respective lab ware site. A plate positioning mechanism is configured to move and position the microtiter plates to and from the lab ware sites of the respective work stations thereof and into engagement with the respective carrier alignment structure thereof. Further, a primary liquid dispensing device is configured for selective contact-type dispensing of discrete quantities of fluid, in the range of about one (1) microliter to about ten (10) milliliters, into the test sites of the microtiter plates secured in the respective alignment structure of the respective work station. The removable secondary liquid dispensing module includes a base member dimensioned to fit substantially within a footprint of a work station, and mounting hardware adapted to removably secure the base member in the work station. A support platform is affixed to the base member, and is configured to support a microtiter-plate. An alignment mechanism is configured to removably receive and secure the a microtiter-plate therein by the plate positioning mechanism of the automated liquid handling system. The support platform and alignment mechanism cooperate to form and provide a lab ware site suitable for secured receipt of a microtiter-plate. The secondary liquid dispensing module further includes a secondary liquid dispensing device which is self-contained and operationally independent from the primary liquid dispensing device. The secondary dispensing device is further adapted for selective non-contact-type dispensing of discrete quantities of fluid, in the range of about one (1) nanoliter to about ten (10) microliters, into the test sites of the microtiter-plate.

A flat sheet of paper, or other thin flexible material, has information printed on one side in the form of a plurality of discrete panels or areas of text or images, while the entire other side is taken up by a large-scale, poster-like pattern. The panels or areas of text or images, are defined by crease lines created by folding the sheet of material. These creases are formed using a perpendicular fold method described in detail in this application. Each fold is perpendicular to the previous fold, creating a grid-like pattern, with each panel in the grid pattern containing a discrete quantity of text or images. When the invention is at its most folded state it has a relatively compact size. As the invention is unfolded, the panels of text or images are revealed in a specific sequence in order to tell a story or communicate some other type of sequentially ordered information. Once the entire sequence of information has been unfolded, the poster-like pattern on the back side of the sheet of material is unfolded and can be viewed and / or displayed.

A method and kit which allow the use of a discrete amount of a binding matrix to first purify nucleic acids from a medium under a first set of binding conditions wherein the amount of nucleic acid bound to the binding matrix is essentially independent of the amount of surface area of the definable amount of the binding matrix, followed by a second purification step wherein the nucleic acids are bound to a discrete amount of binding matrix under a second set of binding conditions wherein the amount of nucleic acid bound to the binding matrix is essentially dependent on the amount of surface area of the definable amount of the binding matrix, thus providing a discrete quantity of nucleic acid.
