Also, a method of operating the aircraft landing gear.

A cleaner head for a cleaning appliance includes a rotatable agitator and an agitator chamber housing the agitator. The agitator includes a drive shaft, a flexible body connected to the drive shaft and surface engaging members mounted on the flexible body. The agitator chamber includes a downwardly-directed opening through which debris energized by the surface engaging members enters the cleaner head. The opening is located in a plane relative to which the flexible body is inclined so that, with rotation of the agitator, the surface engaging members protrude through the opening, preferably towards the front of the opening.

An enclosure device is disclosed for housing a visual display device adjacent to a surface. The enclosure comprises a cabinet defining a cabinet chamber. A face plate defines a continuous frame. A pyramid body defines a cover chamber. The cabinet chamber receives the visual display device. The face plate compresses against the cabinet, for simultaneously positioning the face plate over the visual display device and positioning the pyramid body adjacent to the wall.

A method and apparatus for attaching an ornamental overlay to a vehicle wheel by injecting adhesive foam through an aperture of the wheel and into a cavity formed between the wheel and the overlay. A first nest engages the outboard side of the wheel/overlay assembly to seal the inner periphery of the overlay, the valve stem opening of the overlay, the lug bolt receiving holes of the wheel, the pilot aperture of the wheel, and/or the valve stem opening of the wheel. A secondary nest engages the inboard side of the wheel/overlay assembly to seal the wheel apertures and a plurality of turbine openings in the overlay. A nozzle disposed within the secondary nest is adapted to inject the adhesive foam into the cavity through either a gap between the periphery of a wheel aperture and the periphery of a corresponding turbine opening in the overlay, through a straight or angled hole within a spoke, or through a groove within a spoke.

A cable termination and method of terminating a median barrier cable is described. In one form, the cable termination comprises a tubular body with an opening into which an end of the median barrier cable is inserted. A wedge gripper includes three sections for gripping the end of the median barrier cable within the tubular body. The wedge gripper has a tapering outer surface that mates with a tapered inner surface of the tubular body and has a toothed inner diameter. A threaded cap is screwed to an end of the tubular body opposite from the cable opening, such that the threaded cap forces the tapering outer surface of the wedge gripper axially against the tapered inner surface of the tubular body to force the toothed inner diameter of the wedge gripper to contract against three lobes of the median barrier cable to grip the median barrier cable.

An electrical contactor has a pair of first terminals and a pair of second terminals. Each first terminal has a fixed member with at least one fixed electrical contact facing the other fixed member. The second terminals having back-to-back electrically-conductive movable arms with an electrically-insulating partitioning element there between. Each second terminal is associated with a different one of the first terminals, and has a movable electrical contact on the associated movable arm which faces the corresponding fixed contact. When the contacts close, contra-flowing current through the back-to-back movable arms produces a repulsive force between the movable arms increasing a force between the fixed and movable contacts.

A brake caliper cover to cover the calipers of vehicles having disc brakes. The cover has a mount formed by a body having two ends configured to each engage with the two guide pins for the brake pads housed in a cavity of the caliper. The cover engages to the body of the mount using one or a plurality of supports engaged to the cover which are removably engageable to connectors on the mount.

A power drive mechanism (10) for a motor vehicle liftgate includes a linking arm (18) pivotally connected with the liftgate, a crank arm (12) drivable for pivotal movement and connected with the linking arm (18), and a gear train (20) operatively engaging the crank arm (12). A drive motor (34) is operatively connected with the crank arm (12) through the gear train (20) to provide power assisted opening and closing of the liftgate. The gear train (20) is disengagable from the drive motor (34) to permit manual opening and closing of the liftgate without backdriving the drive motor (34). An actuator (74) is operatively connected with the gear train (20) to move the gear train into and out of engagement with the drive motor. A holding linkage (60, 62) is operatively associated with the gear train (20) to maintain the gear train (20) in engagement during power assisted opening and closing of the liftgate.

A cleaner head for a vacuum cleaning appliance includes a first rotatable agitator and a second rotatable agitator for sweeping debris from a surface, each agitator comprising a disc-shaped body and a plurality of resilient members, preferably in the form of bristles, mounted on the body for engaging the surface. The agitators are housed within an agitator chamber which includes a downwardly-directed opening through which debris energized by the bristles enters the cleaner head. The opening is located in a plane, and each body is inclined relative to the plane of the opening so that, with rotation of the agitator, the bristles protrude through the opening. The bristles of the first agitator are angularly offset from the bristles of the second agitator.

A device and method for positioning a catheter to establish a fluid access site into the vasculature of a patient includes a luer assembly having a cannula or catheter, a shuttle assembly having a stylet for stiffening the catheter, and a holder assembly having an actuator for providing controlled retraction into a handle. The safety catheter comprises a flash window that allows a clinician to view when the vasculature of a patient has been properly accessed and to confirm that the stylet has been fully retracted into a safe position.

Devices and methods for preventing or reducing the severity of hemorrhoids include a raised portion and a base, where the raised portion extends in a first direction away from the base and is shaped to engage and apply pressure to a region of a patient subject to hemorrhoids. The devices may further include a plug for insertion into the anal canal to engage and apply pressure to another region of the patient subject to hemorrhoids. The methods include securing the device in an engagement position to apply the pressure to prevent or reduce the severity of hemorrhoids. Such devices and methods are especially applicable during the childbirth process.

A weighing pan carrier (47) for a balance with a weighing pan and with a weighing cell that includes a load-receiving portion (11) and a stationary portion (12) has an overload protection device against excessive vertically directed forces that is releasably engaged with the weighing pan carrier. The weighing pan carrier (47) is fastened to the load-receiving portion (11) of the weighing cell and has on the other hand a fixed connection to the weighing pan. The weighing pan carrier (47) has a torque safety feature, which is integrated in the overload protection device and provides protection against excessive forces acting tangentially on the weighing pan and/or on the weighing pan carrier (47) in a direction perpendicular to the direction of the weighing load.
