Abstract: A swivelling device is provided for picking up or backing off a drive string after it has been stuck in a down hole. The device allows the drive string to move longitudinally and rotate. The device has a shaft rotatably mounted in a housing so that the shaft can freely rotate but can not move radially or axially relative to the housing. A frame support is moveably connected to the housing and has an aperture that is attachable to a support system capable of lifting up the drive string. A pair of biasing mechanisms bias the housing towards the frame support. When a downward force is applied to the shaft by the drive string, the housing can be displaced downwards away from the support frame. Once the downward force ceases, the biasing mechanism moves the housing back towards the support frame.

Abstract: A gutter system is provided. The gutter system may include a channel that is capable of catching water from a roof. A mounting member may be present and may be configured for at least partially supporting the channel. The channel may be rotationally mounted to the mounting member so that the channel is capable of rotating with respect to the mounting member. The channel can have a force applied thereto in order to thus rotate about an axis of rotation so that debris present in the channel will fall from its interior and thus effect a cleaning of the channel.

Abstract: A power striker assembly effects final positioning of a vehicle closure member and includes a fixed frame and a striker member carried on a striker plate for selective engagement of a latch carried on the closure member, to displace the closure member from a presented position to a cinched position. Guide means interconnects the frame and striker plate to effect simultaneous translational and rotational displacement of the striker plate between end limits of travel to produce linear displacement of the striker member. An actuator selectively displaces the striker plate between its end limits of travel in response to a control signal. Finally, an interlock fixes the striker plate in the cinched position in the absence of the control signal.

Abstract: An equestrian saddle comprises a modular construction including a tree having two side panels connected by a bridge of hinged construction whereby the side panels are angularly adjustable, and a seat plate secured to the side panels.

Abstract: An air flow producer of non-rectangular shape is adapted for installation in a rectangular opening of a drop ceiling. In preferred form, the producer has a circular housing with an open bottom covered with a grill. A fan with a rotary blade assembly is mounted in the housing to produce a downward air flow, and a circular metal band surrounding the rotary blade assembly defines an air discharge zone centered in the grill and an annular air intake zone surrounding the discharge zone. Flow rates are optimized by positioning the band close to the grill. The grill is preferably integrally molded with a rectangular flange that seats in the drop ceiling opening. The flange supports the housing from the framework and closes the opening to prevent the producer from drawing air from the plenum above the drop ceiling.

Abstract: An air flow producer mounted at the ceiling of a room generates an air flow toward the floor, reducing temperature gradients and improving heating and cooling efficiency. A housing defines a circular cylindrical, vertical flow passage that receives the air flow. A discharge chamber discharges the air flow through a grill toward the floor. The discharge chamber has a cross-section that expands progressively from the outlet of the flow passage to the outlet of the discharge chamber. The air flow through the housing is produced by a fan with a rotary blade assembly, and the blade assembly extends partially into the discharge chamber. The position of the blade assembly and the expanding cross-section of the discharge chamber cooperate to increase air flows through the housing. Optionally, an air intake chamber of generally inverted frustoconical shape may be mounted at the upper inlet end of the cylindrical flow passage to smooth flows further.

Abstract: A vehicle door cinching apparatus for assisting the final closing motion of a sliding vehicle door includes an electromagnet, a ferrous metal plate, a cinch drive and a controller.

Abstract: A self-backdriving jackscrew apparatus including a biasing member connected to a screw portion of a jackscrew that exerts backdriving force on the screw to turn the screw in a rotational direction that returns a nut portion of the jackscrew to a home position on the screw.

Abstract: A vehicle door latch has a power operated release mechanism for moving a detent from a latched position to a release position comprising a slide that engages the detent at one end and a rotary cam that engages an opposite end of the slide sot that the slide reciprocates when the rotary cam is rotated by an electric motor. The electric motor drives the cam via a concentric gear wheel that has a pin engaging the rotary cam. A forkbolt rotates a rotary block out lever from a by-pass position to a block out position where the block-out lever engages a shoulder of the gear wheel to stop rotation of the gear wheel when the forkbolt is moved to an unlatched position. The vehicle door latch also includes a mechanical override mechanism to rotate the rotary cam to unlatch the vehicle door latch.

Abstract: A vehicle compartment latch has a support that is fastened to a deck lid. A fork bolt is pivotally attached to the support and moved from an unlatched position to a latched position by a striker when the deck lid is closed. The fork bolt is held in the latched position by a moveable detent lever that is moved to a release position to release the fork bolt so that the deck lid can be opened. The closure latch includes a detent lock-out that holds the detent lever in the release position until the deck lid is opened once the fork bolt is released. The detent lock out includes a striker position lever that is moved to an engaged position by the striker being retained by the fork bolt and a detent pawl that holds the detent lever in the released position once the detent lever is released.

Abstract: A vehicle pivoting closure assembly has a concealed power actuator remotely operated by a controller to open and close a closure or liftgate. A hinge member of the power actuator is engaged pivotally to a vehicle structure about a hinge axis, and rigidly to the closure. An armature extends pivotally from an elongated linear moving rack about a rack pivot axis and to the hinge member. The armature also pivotally engages the hinge member about a secondary pivot axis disposed parallel to the hinge axis and rack pivot axis. The rack is driven by a pinion gear train powered by a motor through a clutch. The hinge, the rack, the gear train and the motor are all supported by a reinforcement tray forming a modular engaged to the vehicle structure. The tray isolates the extreme dynamic loads placed upon the hinge by the motor, thereby eliminating the need to further reinforce the vehicle structure.

Abstract: A manual release mechanism of a power actuated sliding door used typically for van applications, includes a bullet assembly interconnected between the ends of a pull member, or cable, of a powered pulley system. The bullet assembly engages and disengages within a passage of a hinge roller assembly which rides within a track of the vehicle. When disengaged, the door is free to slide without causing movement of the bullet assembly or powered pulley system. When engaged, the hinge roller assembly supports a pin which projects into the passage when in a rest position. If the bullet assembly is in the passage, the pin also projects into a groove of the bullet assembly, thereby, locking the bullet assembly within the passage and causing the hinge rolling assembly, which is pivotally connected to the door to move via operation of the powered pulley system.
