摘要:
A suppressor for a firearm is provided, wherein the suppressor can be selectively oriented relative to the firearm. The suppressor has an elongate body, a piston assembly and a cam assembly. A piston of the piston assembly can be fixedly attached to the barrel of a firearm. An indexing ring is radially fixed relative to the piston. The cam lever is selectively movable between a second position, in which the indexing ring is fixed relative to the elongate body, and a first position, in which the indexing ring can rotate relative to the elongate body.

摘要:
A device for suppressing noise from a firearm. In one aspect, the suppressor has an elongate body that defines a bullet pathway extending longitudinally therethrough. The elongate body may define a plurality of adjacent chambers spaced along its longitudinal axis. The suppressor may also have at least two elongate body shells configured to selectively substantially envelop the elongate body and substantially enclose each of the adjacent chambers. The body shells of the suppressor are designed to be easily removed to clean the chambers of the suppressor.

The invention provides an apparatus for unloading rolled material from a cantilevered support mandrel including a first guide rail extending generally parallel to the cantilevered support mandrel, a second guide rail extending generally perpendicularly to the cantilevered support mandrel, and a carrier for receiving rolled material from the mandrel, the carrier being adapted and configured for movement along the first axis relative to the support mandrel and generally vertical movement along the second guide rail relative to the support mandrel. The invention also provides a method of unloading rolled material from a cantilevered support mandrel.

A method and means of identifying nucleic acid oligomers is disclosed. A sample is split into parts and the parts are flowed through chromatography columns containing nucleic acid oligomer probes bound to a binding medium. Analyte oligomers are transiently hybridized to complementary probe oligomers during chromatography. Detection and analysis of oligomer peaks is used to identify the oligomers contained in the sample.

A web is wound onto an in-line core instead of a separate core. At the start of the winding process, a core-forming substrate attached to the leading edge of the web is wound into an in-line core. The web is wound around the in-line core. For streaming operation, a composite substrate-web stream comprising an alternating sequence of attached core-forming substrate segments and web segments is produced. The first core-forming substrate segment is wound into a first in-line core, and the first web segment is wound around the first in-line core. The composite substrate-web stream is cut. The second core-forming substrate segment is wound into a second in-line core, and the second web segment is wound around the second in-line core. The composite substrate-web stream can be slit longitudinally to produce multiple composite substrate-web stream strips. Multiple composite substrate-web stream strips can be wound in parallel on a single mandrel.

A hinged knee prosthesis includes a femoral component with a tibiofemoral articular surface that is distinct from the patellofemoral articulating surface. Fully congruent tibiofemoral articulation is provided for virtually all flexion angles. Additionally, the bearing is capable of at least limited axial rotation relative to the tibial component but is restrained against dislocation. Accordingly, dislocation is much less likely even n those situations where collateral ligaments are insufficient.

A lock system controls exiting and entering of personnel, particularly in public and commercial structures by means of an alarm and a panic bar and key system to operate a lock through a series of interlocking controls including an internal panic bar, an internal key lock, an external key lock and a supplemental manual control. Four modes of operation are provided in which the panic bar is at all times operative and the alarm is selectively operative to provide, in addition to panic bar actuation or in combination therewith, authorized passage, authorized exit only, free passage in both directions and free exit only.
