An apparatus for holding a breast compression paddle, includes a base, a lip connected to and extending substantially orthogonal from the base, an arm connected to and extending substantially orthogonal from the base and disposed substantially parallel to the lip, and a tine connected to and extending at an angle to the arm. The lip defines a lip plane, and the tine is oriented towards the lip plane. The apparatus is configured to hold and support a compression paddle.

An adjustable truss structure is provided and includes a truss member with a first channel attached to the truss member, the first channel having a first slot, and a rail having a second slot with an anchor attached to the rail. The anchor has a member rotatable to a first position where the member is insertable into the first slot and rotatable to a second position to engage with a surface of the first channel, enabling the rail to be selectively moved relative to the first channel and locked into a fixed position relative to the first channel. The adjustable truss structure also includes a support member having a second channel, the second channel being hooked into the second slot and being slidable in the second slot.

A data processing equipment structure includes a plurality of vertical and horizontal frame components, which, together, define an equipment structure frame, and a plurality of panels disposed relative to the equipment structure frame to define a periphery. At least one of the plurality of vertical and horizontal frame components is an extruded strut having a generally uniform cross-section. The extruded strut includes an outwardly-facing channel extending along each of a pair of opposing sides of the extruded strut, at least one of which includes a set of evenly-spaced ridges, extending along each of two sides of the channel, for accommodating a threaded fastener. The extruded strut further includes one or more ledges, each having a depth sufficient to accommodate a thickness of one of the plurality of panels.

The invention discloses a column-beam connecting assembly capable of being manually assembled, including connecting columns and connecting beams. The connecting column is formed with an arc channel along the axial direction. The arc channel opens to the surface of the column as a groove. A number of pairs of anchor slots are shaped on both sides of the groove, and the anchor slots of the same pair are at the same height. Mounting parts for snapping into the anchor slots are shaped on both sides of the connecting beam. Half T-shaped jointing heads are provided on the outer ends of said mounting pans for connecting to the arc channel, and said jointing heads are either in the shape of a column head matching the arc channel, or in the shape of a hook head. A frame structure assembled by the connecting parts is further disclosed.

Disclosed is an adjustable rack. In example embodiments, the rack may include a rail enclosing a nut used to fix a holder to the rail.

A hollow groove pipe structure is disclosed and includes a hollow groove pipe, first fixing sliding members, second fixing sliding members, and fixing members. The hollow groove pipe has a first surface, a second surface, a third surface, and a fourth surface for surrounding a hollow space. At least two opposite surfaces have grooves, and the bottoms of the grooves are greater (wider) than the opening and provided with trough holes. The plates having a plurality of protruding portions can be clamped in the grooves. The first and second fixing sliding members having protruding portions surround and clamp the plates with the space between the two through holes of the grooves, such that the fixing members pass through the holes of the first fixing sliding member, and the holes of the groove the holes of the second fixing sliding member fix and combine the plates into a whole.

A bar for supporting a table, comprising includes an angle shaped bar having a longitudinal extension, including a first side and a second side extending perpendicular relative each other, at least one first hole through the first side of the angle shaped bar, adapted for connecting two bars together longitudinally so as to form a longer bar, a ridge, extending along the longitudinal edge of the first side of the angle shaped bar, wherein the ridge is adapted to longitudinally limit movement of connected bars.

An edge seal for a modular thermal isolation barrier for preventing passage of air through a gap in a data processing equipment arrangement includes a seal portion and a base portion. The seal portion is formed of a resilient material capable of deflection by a rigid adjacent structure. The base portion is formed of a rigid material and includes a pair of side channels opening at opposite sides thereof and a panel-receiving end channel. Each of the pair of side channels includes a first distal flange arranged to extend inwardly from one side of the respective channel and a second distal flange arranged to extend inwardly, and toward the first distal flange, from the other side of the respective channel, whereby each side channel is generally C-shaped and includes a channel opening having a width that is narrower than a width of a channel interior. Each of the seal portion and the base portion has a generally uniform cross-sectional shape.

A merchandise display stand includes a pair of brackets for carrying a panel having advertising indicia on a first end thereof. A plurality of spaced-apart upright supports extend vertically, and a channel extends across a horizontal support that spans the spaced-apart upright supports. The channel defines an upper and lower flange. The upper and lower flange define a space therebetween for selectively receiving a power cord. Each bracket defines a pair of shoulders on a second end thereof. Each of the shoulders is configured for engaging with a respective flange to receivably engage each of the brackets with the channel.
