20110233323 | SKID-TYPE LANDING GEAR FOR A HELICOPTER - The invention relates to a skid-type landing gear ( | 09-29-2011 |
20130248650 | HELICOPTER SKID TYPE LANDING GEAR - A helicopter with a fuselage and a skid-type landing gear mounted to said fuselage. Said landing gear comprises pivotable cross beams and skids, said skids being each disposed in an essentially longitudinal direction laterally on a respective side of the helicopter's landing gear. At least one discrete damper is provided for at least one pivotable cross beam, said discrete damper being connected with one end to the pivotable cross beam and with another end to the fuselage. The pivotable cross beam are of the cantilever type. Fixed bearings and floating bearings are provided at the fuselage. Torsion bar springs are mounted to said fixed bearings and said floating bearings, said respective inner end of at least one pivotable cantilever cross beam being attached to said torsion bar spring at the floating bearing in such a manner that moments are transferred from the respective inner end of each pivotable cantilever cross beam via said torsion bar spring to the fuselage at said fixed bearing. | 09-26-2013 |

20090102099 | Injection Molding Apparatus Having Magnetic Valve Pin Coupling - A magnetic coupling for an injection molding apparatus, such as a hot half or hot runner, includes a first magnetic part for connection to an actuator, a valve pin plate, or the like and a movable second magnetic part for connection to a valve pin. The first magnetic part and the second magnetic part are coupled by a magnetic force. The first magnetic part can be part of the actuator. The second magnetic part can be part of the valve pin. A valve pin plate can be provided for a plurality of valve pins. | 04-23-2009 |
20120227235 | Method of Taking a Nozzle of a Valve Gated Hot Runner Apparatus Out of Service - A method for taking a nozzle of a valve gated runner apparatus includes releasably attaching a valve pin to a movable part of an actuator for moving the valve pin between an open position and a closed position and detaching the valve pin from the actuator by moving the movable part of the actuator towards the open position when the valve pin is immobilized. The valve pin and the movable part valve pin may be releasably attached by a magnetic force. The step of detaching the valve pin from the actuator may be accomplished by overcoming the magnetic force. A valve pin plate can be provided for a plurality of valve pins to be releasably attached to the actuator. | 09-13-2012 |

20090148551 | Injection Molding Apparatus With Plate Actuation of Valve Pins - An injection molding apparatus includes a back plate, a driven pulley connected to the back plate and rotatable with respect to the back plate, a screw connected to the driven pulley to rotate with the driven pulley, a motor having an attached drive pulley, a belt or chain coupling the driven pulley and the drive pulley, a valve pin plate, a nut connected to the valve pin plate and mated with the screw, at least one valve pin connected to the valve pin plate, a manifold fixed with respect to the back plate, and at least one nozzle connected to the manifold. The valve pin extends through the nozzle to control flow of molding material. The screw can be a ball screw and nut can be a ball nut. The screw can have one portion connected to the driven pulley and another portion connected to a mold plate in a rotatable manner. The valve pin plate may be an assembly with an upper plate, a lower plate, and at least one valve pin holder fixed between the upper plate and the lower plate, the valve pin being fastened to the valve pin plate assembly with the valve pin holder. The positions of the screw and nut can be reversed. | 06-11-2009 |
