20090205336 | Method and Device for the Transfer of Heat from a Heat Source to a Therodynamic Cycle with a Working Meduim of at Least Two Substance with Non-Isothermal Evaporation and Condensation - The invention relates to a thermodynamic circuit with a working medium comprising at least two substances with non-isothermal evaporation and condensation whereby the working medium can decompose above a given temperature. According to the invention, the heat from heat sources at temperatures above the decomposition temperature of the working medium may be made useful with little complexity and with high operational security, whereby the heat from the heat source is transferred in a first step to a hot liquid circuit and, in a second step, from the hot liquid circuit to the circuit with the working medium comprising at least two substances with non-isothermal evaporation and condensation. The heat introduced to the circuit with the working medium comprising at least two substances with non-isothermal evaporation and condensation can be reduced by means of the intermediate hot liquid circuit, such that a decomposition of the working medium can be avoided. Furthermore, the circuit with the working medium comprising at least two substances with non-isothermal evaporation and condensation is embodied as a standardized solution for use with differing heat sources each at differing temperatures, whereby matching to the temperature of the heat source is achieved by means of the intermediate hot liquid circuit. | 08-20-2009 |

20080281313 | System and Method for Laparoscopic Nerve Detection - A surgical system aids identification of nerves in a body to help prevent damage to the nerves during surgery to the body proximate the nerves. An electrode introduced to within a body cavity through a catheter is placed proximate a nerve within the body cavity by a laparoscopic or robotic device. An exploratory probe placed in the body cavity is selectively placed along a presumed pathway of the nerve to provide an electrical signal through the nerve to the electrode. An analyzer interfaced with the electrode analyzes the electrical signal received at the electrode to determine the proximity of the exploratory probe to the nerve, allowing mapping of the nerve pathway through the body cavity. | 11-13-2008 |

20120123292 | Nerve Mapping Surgical System and Method of Use of Dual Function Surgical Instrument Within Such System - A surgical system has an electrode probe, an analyzer, a bipolar instrument, a bipolar power supply and a switch, the switch in communication with the analyzer, the bipolar power supply and the bipolar instrument, to permit alternate use of the bipolar instrument as a surgical instrument and use as an exploratory probe. An electrode probe delivery device has a base plate, an insertion guide connected to and extending from the base plate and formed for receipt of an electrode probe. A catheter on the device permits receipt of at least one electrode probe and a handle connects to the catheter and permits movement thereof such that the catheter is passable through the base plate for introduction into a patient. | 05-17-2012 |

20080274267 | METHOD AND DEVICE FOR METERING A COATING LIQUID IN A PROCESSING MACHINE - A method is provided for metering a coating liquid in a processing machine having a metering device including at least one applicator roller and one counter-pressure cylinder that forms a coating nip and that guides the printing substrate, the metering device being operatively connected to a circulation system for circulating the coating liquid including a supply line, a return line, a reservoir and a conveying pump. The method includes the steps of: pre-selecting, on the main regulation device, a first target temperature value for the coating liquid in a first area defined by the circulation system downstream of the temperature-regulation unit and by the coating nip; conveying the coating liquid using the conveying pump in a direction of the coating nip; detecting a first actual temperature value of the coating liquid at the temperature-regulation unit using a first sensor; detecting a second actual temperature value of the coating liquid in the first area using a second sensor; transmitting at least one signal to the main regulation device for each of the first and second temperature values detected; comparing the second actual temperature value to the first target temperature value using the main regulation device; and sending at least one control signal from the main regulation device as a function of the first detected actual temperature value. | 11-06-2008 |

20090217453 | PLEXIGLAS SURFACE WITH ANTI-SLIP PROPERTIES AND SANITARY ELEMENTS EQUIPPED WITH THE LATTER - PLEXIGLAS® is suitable—when provided with a structured and microrough surface —as an anti-slip covering for sanitary elements. | 09-03-2009 |
20110249939 | LIGHT GUIDE BODY HAVING HIGH LUMINOUS INTENSITY AND HIGH TRANSPARENCY - The present invention relates to light guide bodies having improved luminous intensity and transparency, to a method for their production and to their use. | 10-13-2011 |
20120067512 | LIGHT GUIDE PLATE HAVING EMBEDDED IMPURITIES AND METHOD FOR THE PRODUCTION THEREOF - The invention relates to light guide plates, which are suitable for backlighting LCD monitors as well as information and advertising signs and which are illuminated at the edges and re-emit the light fed at the edges via at least one of the two surfaces located perpendicular to the edges. For the light of a light source that is fed at the edges to be able to leave the light guide plate again via one of the surfaces by overcoming total reflection, the light rays in the light guide plate have to be deliberately deflected. At one of the two surfaces of the light guide plate, the light guide plates are provided with optical impurities ( | 03-22-2012 |
