| 20090136307 | GUIDING DEVICE FOR ENSURING STRAIGHT AND SMOOTH GUIDANCE OF A MOVEMENT - The guiding device has foldable legs that are connected to an upper connector and a lower connector. The legs are foldable along hinges. The hinges to the upper and lower connectors rotatably connect the ends of the legs. The guiding device may be moved from an expanded position to a collapsed position and moves along a straight line L. The guiding device may be used to hold drilling machines and other tools. | 05-28-2009 |

| 20080286462 | Coated insert - The present invention relates to a cutting insert particularly for turning of stainless steel comprising a cemented carbide substrate and a post-treated coating with | 11-20-2008 |
| 20080299366 | CEMENTED CARBIDE INSERT - The present invention relates to a cutting tool insert for parting, grooving and threading in steel and stainless steels comprising a substrate and a coating. The substrate comprises WC, from about 7.5 to about 10.5 wt-% Co, from about 0.7 to about 1.1 wt-% Cr and from about 100 to about 300 ppm Ti. Ti may partly be replaced by Ta to a weight ratio Ti/Ta of equal to or more than about 0.8. The coating comprises two (Ti,Al)N-layers with different Al/Ti-ratios: an inner Al | 12-04-2008 |

| 20100061812 | COATED CUTTING TOOL - The invention relates to a method of producing a cutting tool at least partly coated with an inner CVD coating and an outer PVD coating comprising the manufacturing steps of depositing the CVD coating, subjecting the CVD coating at least partly to an intensive wet-blasting operation, followed by depositing the PVD coating. | 03-11-2010 |
| 20110002749 | COATED CUTTING TOOL INSERT - A coated cutting tool includes a coating and a substrate. The substrate is at least partly coated with a 4-10 μm thick coating comprising two adjacent Ti(C,N)-layers where the difference (Δ) between the residual stress state of the inner layer and the residual stress state of the outer layer is 1000 MPa≦Δ≦2500 MPa, on at least a part of the cutting edge and/or on at least a part of the rake face. A method to produce such a difference between the residual stress states is also disclosed. | 01-06-2011 |

| 20090007912 | Ventilator for Supplying Breathable Gas to a Patient, and a Noise Reduction Method for Said Ventilator - A ventilator for supplying breathable gas to a patient includes an external housing; an internal housing suspended within; a gas flow generator within said internal housing; a gas inlet conduit extending between a first gas inlet opening in said external housing and a second gas inlet opening in said internal housing, and a gas outlet conduit extending from a first gas outlet opening in the internal housing via a second gas outlet opening in the external housing and to a patient interface means adapted for introducing the breathable gas into the airway of said patient. One or both of the gas inlet and outlet conduits exhibit a first substantially rigid conduit section and a second membrane conduit section with a membrane wall portion separating a volume of breathable gas within the gas inlet conduit and/or gas outlet conduit from a volume of ambient air within the external housing. | 01-08-2009 |

| 20100202469 | QUEUE MANAGEMENT SYSTEM AND METHODS - A system and method are provided for managing a queue of packets transmitted from a sender to a receiver across a communications network. The sender has a plurality of sender states and a queue manager situated in between the sender and receiver may have a corresponding plurality of queue manager states. The queue manager has one or more queue management parameters which may have distinct predetermined values for each of the queue manager states. When the queue manager detects an event that is indicative of a change in the sender's state, the queue manager may change its state correspondingly. | 08-12-2010 |
