| 20110027109 | AIR DRIVEN PUMP WITH PERFORMANCE CONTROL - An air driven diaphragm pump includes an performance control actuator having a housing with opposed air chambers. The pump includes pump chambers facing the air chambers and pump diaphragms extending between each air chamber and each pump chamber, respectively. The actuator further includes an air valve, an intake to the air valve and an engagement. The intake includes an intake passage and a performance control intake adjuster rotatably mounted. The intake adjuster has a helical channel and a closure element extending adjustably into the intake passage. The engagement engages the helical channel for control of the intake. The helical channel has varied pitch to provide a nonlinear relationship between rotation and axial advancement of the intake adjuster. The nonlinear relationship gives flow rate proportional to the angular rotation of the intake adjuster. The end points of the channel provide a practical minimum pump performance of about 40% of maximum pump flow rate and a maximum pump performance of about 97% of maximum pump flow rate. | 02-03-2011 |

| 20110019272 | ILLUMINATION DEVICE FOR A MICROSCOPE - The invention relates to an illuminating device for a microscope with an illumination magazine comprising a plurality of light emitting units. A mechanical illuminator changer can change the light emitting unit currently active in the operative position. A filter magazine having a plurality of filter units is present, wherein a mechanical filter changer for changing the filter unit currently in the active operative position is associated with the filter magazine. At least one mechanical coupling means is provided for cooperation with the filter changer and the illuminator and for uniquely assigning each filter unit to a specific light emitting unit. | 01-27-2011 |

| 20090191894 | RADIO NETWORK SYSTEM AND METHOD FOR DETERMINING AN UNKNOWN POSITION OF A TRANSMITTING/RECEIVING UNIT OF A RADIO NETWORK - A method for determining an unknown position of a transmitting/receiving unit of a number of transmitting/receiving units of a radio network, use of a signal quality, and radio network. In the method, a signal field strength and/or a transit time of a signal received through an antenna is measured. A signal quality of the signal received through the antenna is determined. The measured signal field strength and/or the transit time is weighted on the basis of the determined signal quality, wherein the unknown position of the transmitting/receiving unit among the transmitting/receiving units is calculated from multiple weighted signal field strengths and/or transit times and known positions of the transmitting/receiving units. | 07-30-2009 |
