20100258049 | HVPE CHAMBER HARDWARE - Embodiments disclosed herein generally relate to an HVPE chamber. The chamber may have two separate precursor sources coupled thereto to permit two separate layers to be deposited. For example, a gallium source and a separate aluminum source may be coupled to the processing chamber to permit gallium nitride and aluminum nitride to be separately deposited onto a substrate in the same processing chamber. The nitrogen may be introduced to the processing chamber at a separate location from the gallium and the aluminum and at a lower temperature. The different temperatures causes the gases to mix together, react and deposit on the substrate with little or no deposition on the chamber walls. | 10-14-2010 |

20140296869 | SURGICAL INSTRUMENT SHAFT - A surgical instrument may include a shaft, a force transmission mechanism, and an end effector. The shaft may have a proximal end and a distal end. The force transmission mechanism may be coupled to the proximal end of the shaft. The end effector may be coupled to the distal end of the shaft. The shaft may include a body having an outer surface and an inner surface. The inner surface may surround a lumen configured to receive a drive member that extends through the lumen. The outer surface of the body may form an outer surface of the shaft. The body may be made of a single material from the inner surface of the body to the outer surface of the body. | 10-02-2014 |

20160089213 | SURGICAL INSTRUMENT WITH FLEXIBLE SHAFT AND ACTUATION ELEMENT GUIDE - A surgical instrument includes a shaft, a force transmission mechanism disposed at a first end of the shaft, an end effector disposed at a second end of the shaft, an actuation element that extends along the shaft from the force transmission mechanism to the end effector, and an actuation element guide extending along the shaft. The actuation element guide defines a lumen in which the actuation element guide is received. The actuation element guide is compressed into a pre-compressed state along at least a portion of an axial length of the shaft. The actuation element guide can be compressed between first and second blocks of the instrument. The instrument can include a flush tube configured to receive a cleaning fluid, with the actuation element guide being in flow communication with the flush tube to receive the cleaning fluid in the lumen of the actuation element guide. | 03-31-2016 |

20120201638 | METHOD AND ARRANGEMENT FOR MOVING A HEAVY LOAD - Method for moving a heavy load, in which method the heavy load is lifted or lowered with an elevator including an elevator car and a hoisting machine, which hoisting machine is arranged to move the elevator car from one level to another in the normal operation of the elevator, in which method the heavy load is moved to be supported by the elevator car and the elevator car is moved until the load is at the desired height, and the load is removed from the support of the elevator car. In the method a hoist that does not belong to the hoisting machine is temporarily connected to the elevator car for the purpose of moving the load, and the elevator car, which supports the load, is moved by the hoist until the load is at the desired height, and the load is removed from the support of the elevator car. | 08-09-2012 |
20150034425 | ELEVATOR ARRANGEMENT AND METHOD - The invention relates to an elevator arrangement, which comprises one or more elevator units to be moved in an elevator hoistway, said unit(s) including at least an elevator car, and possibly also a counterweight, roping connected to an elevator unit, which roping comprises a plurality of ropes, and a moveable supporting structure in the elevator hoistway for supporting the aforementioned one or more elevator units below it via the aforementioned roping, and a rope pulley or rope pulley stack of the supporting structure in connection with the supporting structure, around which rope pulley or rope pulley stack the aforementioned roping travels, and from which the roping travels down to an elevator unit. The roping travels from the aforementioned rope pulley or rope pulley stack down to an elevator unit, in connection with which is a first rope pulley or rope pulley stack and a second rope pulley or rope pulley stack, which are disposed non-coaxially in relation to each other, their rotation axes being separate from each other in the lateral direction, and in that the first part of the ropes of the roping traveling from the rope pulley or rope pulley stack down to the elevator unit travels to the elevator unit, to the first rope pulley or rope pulley stack that is in connection with the elevator unit, under the pulley or stack, and onwards back up to a rope anchorage arrangement, and the second part to the second rope pulley or rope pulley stack in that is connection with the elevator unit in question, under the pulley or stack, and onwards back up to a rope anchorage arrangement. The invention also relates to corresponding guidance of compensating roping, as well as to a method wherein the service range of the elevator car is increased. | 02-05-2015 |
