摘要:
A fiber optic adapter, including: a mating retainer; an alignment sleeve received in the mating retainer, a ferrule of a fiber optic connector being adapted to be inserted into the alignment sleeve through an insertion port of the fiber optic adapter; and an adjustment element configured to adjust a circumferential angle of the alignment sleeve relative to the mating retainer to a predetermined circumferential angle and hold the alignment sleeve at the predetermined circumferential angle relative to the mating retainer. The adjustment element may adjust the circumferential angle of the alignment sleeve with respect to the mating retainer to the predetermined circumferential angle, for example, at which the fiber insertion loss of the coupled connectors is minimal, and hold the alignment sleeve at the predetermined circumferential angle. In this way, it may improve the alignment accuracy of the coupled connectors.

A connector assembly (10) is disclosed in which a connector part (12) and a cable manager part (20) are provided. The cable manager part (20) can be provided with a separable lacing fixture (24) that functions to retain the severed portions (6a) of the wires (6) that result from the termination process, rather than allowing the severed wire portions (6a) to fall to the floor in an uncollected state. In one aspect, the cable manager part (20) has a main body (22) to which the separable lacing fixture (24) is attached via a plurality of breakaway portions (34). During installation, the connector part (12) is inserted onto the cable manager part (20) and is placed in a wire termination tool (7) which fully inserts the connector part (12) onto the cable manager part (20). This action causes the connector part (12) to cut the wires (6) and to sever or break the breakaway portions (34) such that the separable lacing fixture (24) is separated from the fully formed connector (10).

A closure (100) is configured to hold one or more termination arrangements (120) at which one or more connectorized ends of optical cables can be received. The closure (100) provides axial pull-out protection for the connectorized ends (142) of the optical cables (140). In certain implementations, the closure (100) provides axial pull-out protection for the connectorized ends (142) of optical cables (140) arranged in multiple layers within the closure (100). In certain implementations, the closure (100) provides axial pull-out protection for standard optical connectors (e.g., standard SC connectors, standard LC connectors, standard LX.5 connectors, standard MPO connectors, etc.). The axial pull-out protection can be in the form of a cover (130). Cable bend protection (136) may also be provided by the cover.

A hand-tool is provided for installing and removing a tyre, comprising a substantially elongated body member having a longitudinal axis, the body member further comprising a handle portion (102); a first engagement portion (108), arranged at a first end of said handle portion, adapted to operably engage with a first flange of opposed first and second rim flanges of a wheel, so as to form a fulcrum on the contact point with the first flange; a second engagement portion (112), spaced apart at a predetermined distance in a direction away from said first engagement portion along said longitudinal axis, adapted to abutingly engage with a rim-overlapping bead portion of a tyre.
摘要:
The methods of the present invention exploit unique biochemical pathways present within infectious organisms to develop small molecule metabolic tracers. Labeled substrates created using these inventive methods were created. The labeled substrates can be used to determine whether a subject is infected with an infectious organism by imaging means, and with use of two or more such labeled substrates, methods of differentiating gram negative infection from gram positive infection, and methods of localizing and quantifying infectious disease burden are provided. The methods of the present invention can assist in the clinical decision to begin empiric antibiotic therapy, determine its efficacy, as well as the choice of antibacterial agents.
摘要:
A dispensing device includes a housing, a fan, and an annular reservoir. A compound is disposed within the reservoir. The dispensing device further includes a permeable substrate in communication with the annular reservoir for releasing the compound in a first passive state. The compound is released from the permeable substrate according to a uniform diffusion profile. Rotation of the fan causes air to pass over the permeable substrate to release the compound in a second active state.
摘要:
A method of filtering a fluid using a plurality of filter panels arranged in a plurality of discs, the method comprising directing a flow of unfiltered fluid between a pair of adjacent discs; passing the unfiltered fluid through a pleated filter media that at least partially defines each of the panels; selectively rotating the plurality of discs; and selectively backwashing the filter panels.
摘要:
In one embodiment the method comprises the steps of providing a first template having a predetermined pattern; impressing the first template into the asphalt surface when the asphalt surface is in a pliable state to form an impression therein; removing the first template from the asphalt surface to expose the impression; providing a second template having a predetermined pattern matching the pattern of the first template; inserting the second template into the impression; and fixing the second template in position within the impression to form the inlaid pattern. The second template may consist of a preformed thermoplastic grid having a color and/or texture contrasting with the asphalt surface. In another embodiment the second template may include a light source for illuminating the template after it has been fixed in position. A heating method is described for gradually heating large asphalt surfaces using a reciprocating bank of infrared heaters to thermally fix the thermoplastic grid in place.
