摘要： A rollator includes a support frame assembly, a handgrip unit pivotable relative to the support frame assembly between depressed and non-depressed positions, at least three wheels mounted pivotally to a bottom portion of the support frame assembly, and at least one braking device including a brake wire unit connected to the handgrip unit, and a brake fixed to the support frame assembly at a location proximate to one of the wheels and connected to the brake wire unit. The brake includes a casing, a stop member, and a gear connected coaxially to one of the wheels. The stop member is movable between free and braking positions where the stop member is spaced apart from and is engaged with the gear, respectively.

摘要： The present disclosure is directed, at least in part, to a self-ligating orthodontic bracket system that includes a rotatable member for securing an archwire within a slot of a bracket. Embodiments of the orthodontic bracket system disclosed herein include a bracket body containing the archwire slot as well as tie wings for attaching various orthodontic devices (e.g., elastomeric bands) to the bracket. The rotatable member is rotatable in a first direction (e.g., counter clockwise) relative to a body of the bracket for securing or locking the archwire within the slot, and for rotating in an opposite direction (e.g., a clockwise direction) relative to the bracket body for unsecuring or unlocking the archwire so that it is substantially unrestrained from exiting the slot. Other embodiments include an orthodontic appliance and method of producing and using the same, and preferably employed in a lingual orthodontic system, that includes friction reducing features between an interior of an archwire slot portion of the appliance and an archwire placed within the archwire slot.

摘要： A support arrangement for supporting covering elements on a soffit and/or a fascia of a building. The support arrangement has a backing member that is operable to receive covering elements and is formed at least partially from non-metallic material. The support arrangement further has an attachment means for attaching the support arrangement to a building or building component such that it forms a part of the building. The support arrangement is non-flammable and can easily receive fixings to fix covering elements thereto. Covering elements can be fixed to the support arrangement and then the arrangement can be attached to a building or building component such that the covering elements form a part of the soffit or fascia of the building.

摘要： The present invention relates generally to lighting systems employed in outboard motors used as marine propulsion systems, and to marine vessel assemblies employing outboard motors with such lighting systems, and related methods of operation and implementation. In one example embodiment of a lighting system, the lighting system includes a first cowling panel portion including a reflective strip portion, and a second cowling panel portion that, in combination with the first cowling panel portion, at least partly defines an interior region within the cowling. The lighting system also includes a lighting source that is positioned within the interior region and positioned so that, when operating, first light is emitted toward the reflective strip portion and, upon the first light reaching the reflective strip portion, at least some of the first light is directed outward away from the cowling.

摘要： A foundation interface device for pulling a cable (16) that is arranged in a conduit into a structure. The interface device has a flexible, generally cylindrical pull-in member (12) that is connected to the conduit. At the leading end of the pull-in member is a weak link latch having releasable arms (72) connected to the pull-in member and connection piece (66) connected to the cable. At the rear of the pull in member is a slidable sleeve operably connected to extendable teeth (40). The slidable sleeve has an abutment (36) that contacts an opening of the structure when the interface device is pulled into the opening, causing the sleeve to slide rearward at thus extending the teeth to lock the interface device in the opening.

摘要： A weak-link latch for releasably pulling a cable (13) arranged in a conduit (14). The weak link latch is releasably connected to the conduit, and securely connected to the cable. A plurality of arms (4,5) extend laterally from a central member (1) arranged to engage the conduit, with at least one of which arms being a rotatable arm (5,19), rotatable about an axle (6) from an extended position in locked engagement with the conduit to a collapsed position disengaged from the conduit. A shear pin (7) is arranged between the rotatable arm (5,19) and the central member (1), the shear pin arranged to prevent rotation of the rotatable arm from the extended position to the collapsed position, said shear pin having a predetermined breaking force, said breaking force being a shear force due to rotational force from the rotatable arm.

摘要： Boiler systems and associated control systems, methods for operating same, are described herein. In one example embodiment, a boiler system includes a furnace, an exhaust passage, an air passage, a FGR passage, a flue gas valve that is adjustable by way of a first actuator, a NOX gas sensor, an oxygen gas sensor, and an additional valve that is adjustable by way of a second actuator. Further, the boiler system includes at least one processing device coupled to the NOX gas sensor, the oxygen gas sensor, the first actuator and the second actuator. The at least one processing device is configured to generate control signals that are provided to the first actuator and second actuator, and also configured to generate correction factors by way of a calibration process and to utilize one or more of the correction factors in determining one or more of the control signals.
