An irrigation-suction handpiece assembly, for dental and surgical use at an operating site, includes a handle containing longitudinally extending, side-by-side suction and irrigant passageways respectively connectible to a source of subatmospheric pressure (i.e., a vacuum source) and an irrigant fluid source. An irrigant valve is actuable for alternately opening and blocking flow of irrigant from the irrigant source through the irrigant passageway. An air pressure conduit includes a third passageway in the handle and connectible to an air pressure source which is not atmospheric pressure and not influenced by pressure changes in the suction passageway. This air pressure source is either a further subatmospheric pressure source or a compressed gas source. The third passageway has a relief opening in the handle selectively openable or closable by the hand of the operator for effecting a change in the pressure within the third passageway. The irrigant valve has a control input coupled with the air pressure conduit and third passageway and responsive to such change in air pressure therein for shifting between its open and blocking states to thereby control the flow of irrigant fluid to the operating site.

A rail system (100) is disclosed which may be employed within a commercial interior (102). The rail system (100) comprises a series of primary-tracks (130) in a spaced apart configuration. The rail system (100) also comprises a series of cross rails (132) releasably interconnectable to the primary tracks (130). The rail system (100) permits electrical and mechanical interconnections and reconfiguration of electrical and mechanical interconnections, for various functional accessories and communications.

A space division system (600) includes side sections (604) connected to an overhead structural channel system (606) through support pole assemblies (617). Material support linkage assemblies (610) include an upper material support linkage assembly (614) and a lower material support linkage assembly (612) coupled to the side sections (604). The material support linkage assemblies (610) include adjustable links (616) pivotable relative to each other for forming various configurations of the space division system (600).
摘要:
A storage unit includes a first and second horizontal shelf member, at least one vertical panel disposed between the first and second horizontal shelf members, and at least one tie member. A bottom of the at least one vertical panel is supported by the first shelf member and the second shelf member is supported on a top of the at least one vertical panel. The at least one tie member extends between and connects the first and second horizontal shelf members, with the at least one panel clamped therebetween. In another aspect of the invention, a method for assembling a storage unit is provided.
摘要:
A modular tile and modular tile system is disclosed. The modular tile includes a base structure having a generally horizontal portion. Floor support members are positioned on a bottom surface of the generally horizontal portion. Upper column members extend above the horizontal portion of the modular tile. A cover is supported by the upper column members a distance above the horizontal portion thereby creating a chamber between the horizontal portion and the cover. The chamber is adapted to receive cabling therein.
摘要:
This invention is directed to a shelf assembly having a shelf, a mounting block and a barrier member. The shelf has a first edge. The mounting block is attached to the first edge. A barrier member is adapted to be attached to the mounting block. The barrier member is capable of being oriented in at least two positions with respect to the shelf. The two positions include an article retaining position and an article access position.
摘要:
A table includes a support leg having an elongated channel extending longitudinally along at least a portion of the support leg and opening laterally outwardly from said support leg. The channel has an open end at a top of the support leg. In a preferred embodiment, a catch member extends across at least a portion of said channel and a worksurface is supported by the top of said support leg. In another aspect, the worksurface has a cutout shaped to receive at least a portion of the top of the support leg with at least a portion of the channel nested in the cutout. In a preferred embodiment, the support leg includes a socket that is shaped to receive a portion of the worksurface. A method of routing a utility line on a table is also provided.
