Abstract: In a four-wheel drive vehicle, a rear differential includes an input shaft to which a driving force is transmitted from front wheels through a propeller shaft, a driven bevel gear mounted on the input shaft, a follower bevel gear mounted on a clutch drive shaft and meshed with the driven bevel gear, left and right electromagnetic clutches disposed between opposite ends of the clutch drive shaft and left and right output shafts. The maximum transmitted torque transmitted through the left and right electromagnetic clutches is controlled, so that it is decreased with an increase in vehicle speed detected by vehicle speed detecting means. Thus, the vehicle can avoid the maximum horsepower transmitted by the bevel gears and the electromagnetic clutches being increased with an increase in vehicle speed. Therefore, it is possible to ensure the durability of the bevel gears and the clutches, while providing a reduction in size of the bevel gears and the clutches.

Abstract: A backup power circuit provides reserve power to a terminal device in the event of loss of power from the main power source.      In the terminal device, the main power source is connected to a power circuit which generates two different voltage signals used by different circuits therein. The backup power circuit selectively stores energy from the higher voltage signal and supplies the stored energy to the power circuit when the main power fails, thereby allowing the power circuit to generate the lower voltage signal.

Title: Downhole fluid separation system incorporating a drive-through separator and method for separating wellbore fluids
Inventor: MANN JAY S
IPC: B01D17/02
Filed: 1999-01-12
Granted: 2006-08-08
Abstract: A fluid separation system is provided for separating wellbore fluids into production fluids and non-production fluids. The system includes a separator adapted for transmitting mechanical power between a drive motor and at least one pump.  The separator includes one or more separation units, such as hydrocyclone separators. A drive train traversing the separator is interfaced with drive elements, such as a submergible electric motor, and driven elements such as an injection or production pump. Wellbore fluids are channeled through the separator in either a push-through or pull-through manner. Production fluids are then transferred from the separator to the production pump for removal from the well. Non-production fluids are transmitted from the separator either to the injection pump for reinjection into a subterranean discharge zone, or directly into the discharge zone from the separator. The drive train elements traversing the separator are supported by antifriction bearings in interface plates on either end of the separator. The ability to transmit mechanical power through the separator facilitates assembly of pumping system components in various configurations as well as piping fluid communication paths between the pumping system components.

Abstract: A sidewall of a trailer is formed from at least two composite panels joined together by a novel joining configuration. Each panel is formed from inner and outer thin metal skins and a plastic core sandwiched between the skins. In several embodiments, at least one of the skins has at least one end coined to as to compress the core between the skins to define a coined end section. A logistics plate and a splicing member are used to join the panels together and are secured thereto by rivets.      The logistics plate and/or the splicing member may sit against the coined end sections. The splicing member may have flat top and bottom portions to facilitate in the attachment of the panels to the top and bottom rails of the trailer. In other embodiments, a logistics plate is secured by rivets to the panels for joining them together. The splicing member is eliminated and instead, the outer skin of at least one panel is extended to lie behind the logistics plate. In yet another embodiment, the inner skin may have rolled or formed grooves to provide a smooth transition from a logistics plate having rolled edges. An insert may be used between the skins where the rivets are inserted in any of the embodiments to substantially prevent compression of the panels.

Abstract: An improved coupling arrangement is provided for coupling connected to the top of a plunger which reciprocates in a pump barrel. The coupling provides fluid ports for discharging fluid from the bore of the plunger and coupling to the annulus between the coupling and pump barrel. The lower edge of the ports is positioned below the leading edge of plunger, or conversely the leading edge of the plunger is re-formed above the lower edge; of the coupling's ports. Accordingly, solids cannot be trapped between the leading edge of the plunger and barrel and pump live is markedly improved. Preferably the plunger's leading edge is formed by the novel coupling so that industry standard plunger's can be used. Further, the plunger's leading edge is preferably fitted with a wiper which is even more preferably backed by a stack of seals fitted into a pressure-equalized annulus located below the wiper.
