| 20090095004 | SYSTEM FOR PRODUCING AIR - A system for the provision of process air comprises a first cooling system ( | 04-16-2009 |
| 20090255277 | OPTIMIZED DEFROSTING REGULATION OF PARALLEL ARRANGED FRESH AIR OUTLETS OF AIR CONDITIONERS - An arrangement is provided for de-icing pipeline connections of an aircraft, which are connected to all fresh air outlets of an air conditioner, whose construction includes, but is not limited to the functions of multiple turbines and heat exchangers, having a first pipeline, which is connected to a first turbine, and a second pipeline, which is connected to a second turbine, the two pipelines, which are each connected downstream from the two turbines and to which process air is fed at the turbine outlets, being connected at the pipe ends and being continued using a third pipeline. The arrangement is characterized in that a first hot air source is fed hot fresh air from a bleed air system of the aircraft and is connected at its outlet to a fourth pipeline, into which temperature-reduced fresh air is fed from the hot air source. The fourth pipeline is connected at its pipe end to two further valve-regulated pipelines, of which a fifth or a sixth pipeline is connected to the first or the second pipeline, and through which temperature-reduced fresh air is transported and fed valve-regulated to the first and/or second pipeline. | 10-15-2009 |
| 20090308978 | Relief valve for being arranged on an opening of a fuselage shell of an aircraft, fuselage part with such a relief valve and aircraft fuselage - The invention pertains to a relief valve ( | 12-17-2009 |
| 20100101251 | Method And System For Controlling An Aircraft Air Conditioning System With Optimised Fuel Consumption - In a method for controlling an aircraft air conditioning system ( | 04-29-2010 |
| 20110111683 | System For Ventilation Of An Aircraft Area | 05-12-2011 |
| 20110177771 | System For Cooling An Aircraft Zone, To Be Connected To An Aircraft-External Air Unit | 07-21-2011 |
| 20110247432 | Aircraft Conduit Monitoring System And Method - The invention relates to an aircraft conduit monitoring system comprising a conduit that conducts gas from a source to a point of application. A flow sensing device and a pressure sensing device are provided within the conduit. At least one set value of a gas mass flow rate and at least one set value of a pressure are sensed in a learning mode of operation. Said set values are compared with sensed actual values in the normal mode of operation. A gas volume flow rate can also be sensed and processed instead of a gas mass flow rate. | 10-13-2011 |

| 20110309784 | COUNTER ELECTRO-MOTORIC FORCE BASED FUNCTIONAL STATUS DETECTION OF AN ELECTRO-MOTOR - The present invention relates to a circuit for detecting a functional status of an electro-motor. Typical electro-motors need additional components to identify the functional status of the motor. This means additional weight for such motors determining the functional status. According to the present invention a circuit is provided using a part of a motor as a sensor for detecting the functional status of the electro-motor. | 12-22-2011 |

| 20090159402 | SHOPPING CART CONVEYOR SYSTEM WITH PIVOTING LUG - A shopping cart conveyor system that moves a shopping cart from one location to another along a path. The system includes a frame, a track coupled to the frame, and a conveyor coupled to the frame and having an engagement member (e.g., multiple engagement members) adapted to engage a shopping cart. The engagement member is movable (e.g., pivotable) relative to the track from a first position, where the engagement member will engage and move the shopping cart along the path, and a second position, where the engagement member is capable of releasing engagement of the shopping cart. Preferably, the engagement member is biased toward the first position (e.g., by a resilient member). In one embodiment, the engagement member includes an engagement surface adapted to engage the shopping cart and defining an engagement angle between the engagement surface and a reference axis parallel to the path. In this embodiment, the engagement angle is acute when the engagement member is in the first position and is obtuse when the engagement member is in the second position. | 06-25-2009 |

| 20110147164 | SHOPPING CART CONVEYOR WITH GATE ASSEMBLY - A conveyor for moving a shopping cart between a first location and a second location. The conveyor including a movable conveyor that is adapted to engage and move the shopping cart along a path, and a gate assembly including a door that is movable between an open position allowing passage of the shopping cart along the path, and a closed position inhibiting passage of the shopping art along the path. The door is adapted to move from the closed position to the open position as the shopping cart approaches, and is adapted to move back to the closed position before the shopping cart has passed the door. | 06-23-2011 |
