20110208200 | VETERINARY PRECISION FIXATION DEVICE AND METHOD OF USING THE SAME - A veterinary precision fixation device for use in tibial plateau leveling osteotomy procedures includes a jig assembly having a center jig member having a first and a second end, a first jig leg pivotally coupled to the first end, and a second jig leg pivotally coupled to the second end. The device also includes a saw positioning assembly including a positioning arm and a guide leg, the positioning assembly being operably connected to the jig assembly. The device further includes a saw guide assembly having a saw fixation member slidably coupled to at least one slide bar wherein the slide bar is coupled to the guide leg of the saw positioning assembly. A method for using the precision fixation device in a tibial plateau leveling osteotomy is also provided for making a substantially perpendicular cut of the tibia. | 08-25-2011 |

20130098490 | GAS MANIFOLD SYSTEM FOR STEADY GAS SUPPLY AT OUTLET - A gas manifold system includes a plenum that receives a gas at a positive pressure and a manifold having at least one exit port. One or more valves are disposed between the plenum and the manifold. When opened, the valve(s) permit a stream of the gas at positive pressure to flow from the plenum into the manifold. A baffle is disposed in the manifold between the valve(s) and the exit port(s). The baffle obstructs each stream of gas entering the manifold such that the gas is reduced to substantially zero pressure in the manifold at the exit port(s). | 04-25-2013 |
20140158079 | ADJUSTABLE VENTURI MIXING VALVE ASSEMBLY - A venturi mixing valve assembly includes three open-ended tubular sections. A first section, coupled to a supply of a first gas and a supply of a second gas, has a sleeve defined therein wherein an annular channel open on one end thereof is defined between the sleeve and an inner surface of the first section. A second section defines an annular region with a plurality of holes and a venturi region coupled to the annular region. The annular region circumscribes at least a portion of the first section's sleeve. A third section is threadably coupled to outer surfaces of the first and second sections such that rotation of the third section in a first direction causes the first and second sections to move axially towards one another, while rotation of the third section in a second direction causes the first and second sections to move axially away from one another. | 06-12-2014 |

20080257555 | Linear Drive Assembly with Rotary Union for Well Head Applications and Method Implemented Thereby - A drive assembly for a progressive cavity pump includes a frame supported by the wel piping and a polish rod connected to the sucker rod. The polish rod is received by a rotary union formed by a sleeve portion rotatable with respect to a body portion with a seal structure that seals the sleeve and body portions during rotation. A mechanical drive, such as a hydraulic motor, electric motor or engine, has an output shaft that is linear with the polish rod and that has an axial passageway which receives the polish rod. A coupler mechanically couples an upper portion of the polish rod to the output shaft. The invention also includes a method of rotating a progressive cavity pump by this assembly. | 10-23-2008 |

20090077814 | Cutting Angle Indicator in Jigsaw Housing with Dust Extraction - A jigsaw generally includes a housing containing a motor activated by a trigger assembly. The housing defines a window. A shoe member pivotally connects to the housing. An indicator wheel is disposed in the housing so that a portion of the indicator wheel is visible through the window, wherein pivoting of the shoe member relative to the housing causes the indicator wheel to rotate. | 03-26-2009 |
20090077820 | Control of Reciprocation Speed and Orbital Magnitude of a Jigsaw with a Plurality of Material and/or Task Descriptive Icons - A jigsaw generally includes a housing containing a motor activated by a trigger assembly. A single control member is connected to the housing and configured to be accessible by a user. A reciprocating shaft moves at a reciprocation speed and at a magnitude of orbital motion when the trigger assembly is in a retracted condition. The single control member is operable to be positioned among a plurality of positions. Each of the positions corresponds to a predetermined combination of values of the reciprocation speed and the magnitude of the orbital motion. | 03-26-2009 |
