| 20100115802 | HYDRAULIC BACKHOE SHIFT MECHANISM - An earth-working vehicle, such as a backhoe loader, has an implement, such as a backhoe, mounted in a manner that the implement can be shifted transversely with respect to the vehicle. A hydraulic motor and roller cable or rack are secured to the vehicle main frame and implement supporting plate to position the implement transversely of the vehicle without the jerky movements of prior backhoe loaders. | 05-13-2010 |
| 20110030363 | Open center hydraulic system - An open center hydraulic system that includes a variable displacement pump having an inlet, an outlet and a sensing port, the pump configured to provide reduced fluid flow in response to a predetermined fluid pressure differential between the outlet and the sensing port. A first fluid circuit and a second fluid circuit each serve as signal lines with the pump sensing port. During operation of the second fluid circuit, reduced fluid flow from the pump outlet is achieved as a result of the sum of induced fluid pressure reductions of respective controlled pressure reduction devices approaching the predetermined pump fluid pressure differential. | 02-10-2011 |
| 20120096843 | WORK VEHICLE LIFTING PERFORMANCE - A work vehicle includes a fluid circuit to operate at least one implement for performing work, the fluid circuit having at least a first operating mode and a second operating mode. The first operating mode is configured to operate within a first predetermined flow rate range within a first predetermined fluid pressure level range. The second operating mode is configured to operate within a second predetermined flow rate range and within a second predetermined fluid pressure level range. In response to the fluid circuit operating within the second operating mode, a maximum pressure value of the second predetermined fluid pressure level range is greater than a maximum pressure value of the first predetermined fluid pressure level range, and a maximum value of the second predetermined flow level range is less than a maximum value of the first predetermined flow level range. | 04-26-2012 |

| 20100001520 | PVC Pipe Coupling - A threaded coupling for connecting a threaded first connecting drop pipe to a second connecting drop pipe. The coupling has a first female end having an enlarged exterior diameter and an interior diameter defining a lead in section which provides strength to resist lateral forces exerted on the threaded drop pipe connection. Adjacent the lead in section, internal threads are located in the first female end of the coupling. A second female end having an interior diameter substantially the same size as the lead in section of the first female end is located adjacent the internal threads, opposite the first female end. A male connecting end of a first connecting drop pipe having external threads is inserted into the lead in section and screwed into the coupling. A male connecting end of a second connecting drop pipe is coated with an adhesive and inserted into the second female end. | 01-07-2010 |
| 20100194098 | Push Lock Pipe Connection System - A pipe for connecting to a similar adjacent pipe. The pipe has a female end with a plurality of rigid fingers extending into the space within the female end. The plurality of rigid fingers extends from at least one interior circumferential groove on the interior surface of the female end. On the male end of the pipe there is at least one exterior circumferential groove that is sized and positioned to receive the plurality of rigid fingers from a corresponding interior circumferential groove on the female end of an adjacent pipe. The number of interior circumferential grooves on the female end with the plurality of rigid fingers extending from them typically corresponds to the number of exterior circumferential grooves on the male end. When the male end of a similar adjacent pipe is inserted into the female end of the pipe, the plurality of rigid fingers is received within the corresponding exterior circumferential groove on the male end, thereby preventing the male end of the similar adjacent pipe from being withdrawn from the female end of the pipe. | 08-05-2010 |
| 20100194104 | MALE PUSH LOCK PIPE CONNECTION SYSTEM - A pipe for connecting to a similar adjacent pipe. The pipe has a male end with a plurality of rigid fingers extending from within and out of at least one exterior circumferential groove disposed on its exterior surface. On the female end is at least one interior circumferential groove sized and positioned to receive the plurality of rigid fingers from a corresponding exterior circumferential groove on the male end of an adjacent pipe. The number of exterior circumferential grooves on the male end typically corresponds to the number of interior circumferential grooves on the female end. When the male end of the pipe inserts into the female end of a similar adjacent pipe, the plurality of rigid fingers is received within a corresponding interior circumferential groove on the female end, thereby preventing the male end of the pipe from being withdrawn from the female end of the similar adjacent pipe. | 08-05-2010 |
| 20110012339 | Push Lock Pipe Connection System and Disconnection Tool - A disconnection tool and system for disconnecting pipes which are connected through the connection system disclosed in application Ser. No. 12/365,000 and/or connections systems similar thereto. The disconnection tool of the present invention positions around a male end of a male pipe that is within a female end of a female pipe. The male end is locked within the female end with one or more locking members extending across a clearance that exists between the interior surface of the female end and the exterior surface of the male end. The one or more locking members engage both the male end of the male pipe and the female end of the female pipe. The disconnection tool has an insertion member that inserts into the clearance and disengages the one or more locking members from the male end of the male pipe or the female end of the female pipe. | 01-20-2011 |
| 20110088239 | Push Lock Pipe Connection System - A pipe for connecting to a similar adjacent pipe. The pipe has a female end with a plurality of rigid fingers extending into the space within the female end. The plurality of rigid fingers extends from at least one interior circumferential groove on the interior surface of the female end. On the male end of the pipe there is at least one exterior circumferential groove that is sized and positioned to receive the plurality of rigid fingers from a corresponding interior circumferential groove on the female end of an adjacent pipe. The number of interior circumferential grooves on the female end with the plurality of rigid fingers extending from them typically corresponds to the number of exterior circumferential grooves on the male end. When the male end of a similar adjacent pipe is inserted into the female end of the pipe, the plurality of rigid fingers is received within the corresponding exterior circumferential groove on the male end, thereby preventing the male end of the similar adjacent pipe from being withdrawn from the female end of the pipe. | 04-21-2011 |
| 20110156384 | Pipe With Reinforced Female End - The present invention relates to a length of pipe with a female end that is reinforced by a band of reinforcing material that extends around the female end. When the pipe and a similar adjacent pipe are threadably connected, the reinforcement material reinforces the female end against failure due to hoop stresses and/or lateral stresses. In this regard, the reinforcing material is any material with a higher resistance to hoop stresses and/or lateral stresses than the material from which the pipe is made. The present invention is also directed to manufacturing processes for manufacturing the pipe of the present invention. | 06-30-2011 |
