The tie rod assembly union includes a tube sleeve and a tie rod shaft that extends into the tube sleeve such that the tie rod shaft and the tube sleeve overlap with one another. In the overlapping area, each of the tie rod shaft and the tube sleeve has at least one set of openings. A C-shaped clamp is disposed about the tube sleeve. The clamp has a curved inner surface which engages both tube sleeve halves. The clamp has a first set of apertures which are spaced outwardly from the curved inner surface and a second set of apertures which extend to the curved inner surface. A first fastener extends through the first set of apertures to tighten the clamp onto the tube sleeve. A second fastener extends through the second set of apertures and through aligned openings in the tie rod shaft and tube sleeve.

A first case includes a first plurality of threads, a second case includes a second plurality of threads, an interface provides at least one of anti-rotation or alignment with respect to the first case and the second case, and a nut includes a third plurality of threads configured to engage with the first plurality of threads and a fourth plurality of threads configured to engage with the second plurality of threads.

A tool coupling extends along a longitudinal axis and has a first component, a second component, and a clamp for fastening the first component to the second component. The first component has a male clamping portion, the second component has a female clamping portion, and the clamp is located in an inner cavity of the second component. The male clamping portion has a first abutment region located axially rearward of a first plane perpendicular to the longitudinal axis, the inner cavity has a second abutment region located axially forward of the first plane, and the first and second abutment regions face towards the first plane. In a fastened state, a clamp first engagement region of the clamp makes clamping contact with the male clamping portion's first abutment region, and a clamp second engagement region of the clamp makes clamping contact with the inner cavity's second abutment region.

A channel having a base portion, an open central region, and an integral pair of sidewalls. The integral pair of sidewalls having an upper portion of each sidewall that includes an inward-facing downturned internal flange and an outward-facing upturned external flange.

An electronic sign having slotted frame cabinets, whereby each slotted frame cabinet can conveniently be attached to one or more vertically or horizontally positioned adjacent slotted frame cabinets by using connecting components which are generally located around the periphery of one or more slotted frame cabinets. Connecting components including splice bars, splice plates, and mounting clamps are aligned in, positioned along, and secured to backing bars which are co-located in backing bar slots in one or more of the slotted frame cabinets. Lift eyes can be variably located in one or more lift eye slots. The use of externally located connecting components, which do not extend through the cabinetry, minimize the entry of environmental elements into the interior of the electronic sign. Multiple slotted frame cabinets can be connected without the removal of LED display panels. Bracket assemblies and clamping assemblies are provided.

A connection for connecting a first member with a second member. The connection includes a torque transmitting connection between the first member and the second member and an axial force transmitting connection between the first member and the second member. The axial force transmitting connection includes a first exterior shoulder on the first member, a second exterior shoulder on the second member, a first collar having a first interior shoulder for engaging with the first exterior shoulder, a second collar having a second interior shoulder for engaging with the second exterior shoulder, and a collar connection between the first collar and the second collar for transmitting an axial force between the first collar and the second collar.

An axial preloading device can include a shell having an inner surface that defines a radially interior channel, the inner channel defining an axial direction, one or more moveable housing members disposed at least partially within the interior channel and configured to move relative to the shell in the axial direction, and a wedge assembly connected to the shell and disposed in contact with the one or more housing members. The wedge assembly can be configured to be moved radially relative to the shell and the one or more housing members to push the one or more housing members axially. The wedge assembly and the one or more housing members define a shaft opening when installed on the shell.

Multiple slotted frame cabinets can be connected without the removal of LED display panels. Bracket assemblies and clamping assemblies are provided.

A rigidizing latch assembly comprises a robotically compatible aerospace attachment mechanism which comprises a male latch and a receptacle configured to cooperatively couple. The male latch comprises a male latch housing and a latch assembly movably disposed within the male latch housing; a driver operatively in communication with a latch support; a male latch core; a driver interface access port; and one or more extraction feet operatively in communication with the driver. The receptacle comprises a receptacle housing sized to receive a lower portion of the male latch housing; a positioning target adapted to provide a visual positioning targeting cue; and one or more latch interfaces dimensioned to releasably mate with a corresponding lead-in guide of the plurality of lead-in guides.

A gas turbine engine casing apparatus includes annular first and second annular cases connected by a spigot joint. The spigot joint includes an annular projection of the first annular case fitted into an annular recess of the second annular case. A plurality of circumferentially spaced apart scallops are formed on one of surfaces of the annular projection or of the annular recess, and are located in selective circumferential locations adjacent respective enhanced stiff areas of the first and second annular cases.
