20140338753 | SYSTEMS AND METHODS FOR DROPLET PRODUCTION AND/OR FLUIDIC MANIPULATION - The present invention generally relates to systems and techniques for manipulating fluids and/or making droplets. In certain aspects, the present invention generally relates to droplet production. The droplets may be formed from fluids from different sources. In one set of embodiments, the present invention is directed to a microfluidic device comprising a plurality of droplet-making units, and/or other fluidic units, which may be substantially identical in some cases. Substantially each of the fluidic units may be in fluidic communication with a different source of a first fluid and a common source of a second fluid, in certain embodiments. In one aspect, substantially the same pressure may be applied to substantially all of the different sources of fluid, which may be used to cause fluid to move from the different sources into the microfluidic device. In some cases, the fluids may interact within the fluidic units, e.g., by reacting, or for the production of droplets within the microfluidic device. In some cases, the droplets may be used, for example, to form a library of droplets. | 11-20-2014 |

20110115128 | DEVICE FOR PRODUCING A COMPONENT AND METHOD AND COMPONENT - The invention relates to a device for the production of an angle for connecting a fuselage cell skin to an annular former and/or a stringer inside a fuselage cell structure of an aircraft, the angle taking place by the one-step deformation of an initially planar blank along at least three fold lines in a uniaxial compression moulding device. A mounting frame with hinges is arranged in the compression moulding device, the blank to be deformed being accommodated along the edges preferably by means of a plurality of peripherally arranged springs. A deformation of the blank into an auto-stabilised angle is possible in one step while simultaneously ensuring interlaminar slide. Due to the constructively conditioned auto-stabilisation of the angle, additional components which increase the weight and the assembly effort (so-called “stabilos”) in the connection region between fuselage cell skin, stringers and annular formers inside a fuselage structure of an aircraft are unnecessary. | 05-19-2011 |
