20090145718 | Overrunning Clutch - An overrunning clutch has a first race, a second race, a set of pawls between the first race and the second race and a set of springs between the first race and the second race, one spring for each pawl and each corresponding spring biasing the corresponding pawl into a position in which the first race and the second race are engaged with each other in a driving direction and are disengaged from each other in a free wheeling direction. Each spring is received in a spring receiving recess of one of the races and biases a rearward portion of the corresponding pawl radially inwardly into a pawl receiving recess of the race. | 06-11-2009 |
20100035077 | Powder Metal Forging and Method and Apparatus of Manufacture - A method of forming a powder metal forging, including the steps of: forming a preform including a sintered powder metal composition; inserting the preform in a die set having a bottom die and a top die, the die set defining a forge form therewithin, the die set being in a closed position wherein the top die is contacting the bottom die; and compressing the preform in the forge form using an upper punch and a lower punch, the compressing step resulting in a formed part. The closed die set minimizes or eliminates flash in the formed part, particularly in the contoured surfaces, which allows the forging to be through hardened by direct quenching after the forging operation, without the need to remove hardened flash from these surfaces. | 02-11-2010 |

One of the races includes at least one pawl and an engagement member for holding the at least one pawl in engagement with ratchet teeth on the other race. The contact surface of the at least one pawl or the ratchet teeth is an arcuate shape for improved load distribution. The arcuate contact surface has a radius of curvature that is greater than a radius of curvature at corners adjacent to the arcuate contact surface. | 11-18-2010 |
20110000335 | POWDER METAL FORGING AND METHOD AND APPARATUS OF MANUFACTURE - A method and apparatus for forming a powder metal forging (B) includes a die set (A | 01-06-2011 |
20110059822 | Powder Forged Differential Gear - A differential assembly, bevel gears for the assembly, and a method of making the bevel gears are disclosed. The bevel gears have a form which provides for high power density transfer. | 03-10-2011 |
20110108383 | ONE-WAY CLUTCH RETAINER - A retainer for a one-way clutch is provided. In some embodiments, the retainer includes an annular portion with an inner circumferential surface, an outer circumferential surface and a first axial surface disposed between the inner circumferential surface and the outer circumferential surface. The first axial surface has a plurality of grooves, a second axial surface is disposed between the inner circumferential surface and the outer circumferential surface, and the second axial surface is configured to engage an outer race of the one-way clutch assembly. The retainer also includes a plurality of inner lobes that project generally radially inwardly from the inner circumferential surface, and are configured to engage an inner race of the one-way clutch assembly. | 05-12-2011 |

20090008342 | Apparatus and Method for Separating Immiscible Fluid Components - A separator apparatus for separating immiscible fluid components of different specific gravities. A body includes an internal flow channel for a mixture of fluid components to be separated. A rotation generating device brings the fluid mixture to rotate about the longitudinal axis of the flow channel. An extraction device withdraws a central part of the rotating fluid mixture flowing through the flow channel. A bubble introducer introduces micro-sized gas bubbles into the fluid mixture so as to thereby enhance the separation of the fluid components. Also a method for separating immiscible fluid components of different specific gravities. | 01-08-2009 |
20090211960 | FLUID TREATMENT TANK AND A WELL FLUID PROCESSING SYSTEM COMPRISING SUCH A TANK - A fluid treatment tank for use in a well fluid processing system. The tank is divided into at least three compartments, including an oil treatment compartment for receiving oil from a separator vessel of the well fluid processing system so as to allow stabilization and/or final separation and treatment of the oil, a reject treatment compartment for receiving reject fluid from one or more water treatment units of the well fluid processing system so as to allow gravitational separation of heavier and lighter components of the reject fluid, and a water treatment compartment for receiving de-oiled water from one or more water treatment units of the well fluid processing system so as to allow degassing and/or final separation of the water. Also, a well fluid processing system including such a fluid treatment tank. | 08-27-2009 |

20100000733 | Apparatus and Method for Energy-Efficient and Environmentally-friendly Recovery of Bitumen - The present invention aims at recovering unconventional oil in an environmentally friendly and sustainable way that has the potential of eliminating the need of natural gas currently employed for steam production and power generation. Our invention aims at providing low temperature steam for the stimulation of the formation by means of solar radiation. In addition we propose a novel solution for hydrogen production that does not employ reforming of natural gas. We also illustrate how the use of thermoelectric devices in combination with low temperature steam can be employed to power an electrolysis plant to generate the hydrogen necessary to produce synthetic oil. | 01-07-2010 |
