A bearing clip for joining a truss to a bearing material is disclosed. The bearing clip includes a base portion, a vertical portion, and at least one wing. The base portion includes a back end, sides adjacent to the back end and a bottom surface. The vertical portion extends from the back end of the base portion in a first direction away from the bottom surface. The at least one wing extends from a side of the base portion at an obtuse angle and at least partially in the first direction.

A bracket assembly is disclosed. The bracket assembly comprises a cylindrical member configured to hold a supporting bar at a first opening of the cylindrical member. Further, a cylindrical core housed in the cylindrical member from the second opening of the cylindrical member. Further, an annular cap coupled with the cylindrical core at the second opening of the cylindrical member for providing support to the cylindrical member, a torque cartridge housed within a torque cartridge housing and transversely press fitted into the cylindrical member and the cylindrical core. Further, the torque cartridge comprises a first portion and a second portion, a first end of the first portion is coupled to the cylindrical core, a first end of the second portion is rotatably coupled at a second end of the first portion to provide an infinite smooth pivoting movement between the first portion and the second portion of the torque cartridge.

To provide a fastening member configured to fasten a hollow member including a first wall and a second wall, the first wall and the second wall facing each other, and another member having a screw hole. The fastening member includes a bolt having a screw portion to be inserted through a second hole provided on the second wall and to be screwed into the screw hole, and a case to be inserted into a first hole provided on the first wall, the case being configured to accommodate the bolt. While the case is inserted into the first hole, a tool used for a task of fastening the bolt is inserted into the case from a side of the first wall opposite to the other side of the first wall facing the second wall.

An electrostatic chuck includes a ceramic top plate layer made of a beryllium oxide material, a ceramic bottom plate layer made of a beryllium oxide material, a ceramic middle plate layer disposed between the ceramic top plate layer and the ceramic bottom plate layer, an electrode layer disposed between the ceramic top plate layer and the ceramic middle plate layer, and a heater layer disposed between the ceramic middle plate layer and the ceramic bottom plate layer. The electrode layer joins and hermetically seals the ceramic top plate layer to the ceramic middle plate layer, and the heater layer joins and hermetically seals the ceramic middle plate layer to the ceramic bottom plate layer.

A quadrangular furniture element, in particular a shelf with at least one bearing plane, has a base, a cover panel, and at least one profiled element which is secured between the base and the cover panel. A translation-rotation fitting is arranged on the base lower face facing away from the cover panel and/or on the cover panel upper face facing away from the base, the translation-rotation fitting being usable for moving the furniture element from a starting position into an open end position and back into the starting position in a combined translation-rotation movement, wherein at least one receiving element for fixing the at least one profiled element is arranged in an edge region of the base and the cover panel. A piece of furniture can have at least one such furniture element.

A lattice system for structures includes a lattice joint housing and a plurality of structural joints. Each of the plurality of structural joints have a side entry slot for insertion of keyed features on a mating lattice member. Each of the plurality of structural joints are configured to facilitate rotation of the mating lattice member, semi-permanently holding the mating lattice member in place with an electro-permanent magnetic (EPM) retaining device.

A quick-release device for securing a gas cylinder in a seat plate includes a pedestal defining a socket for receiving the gas cylinder. The pedestal projects upwardly from an endwall to form a jaw against which the gas cylinder is received when applied to the socket. A clamp is pivoted to the jaw for movement between an open position and a closed position. A flange is formed in the pedestal and has a lower surface for confrontation with the seat plate. A latch is coupled to the pedestal. The latch moves between a first position enabling movement of the clamp between the open and closed positions, and a second position disabling movement of the clamp between the open and closed positions.

For the economical and energy-efficient use of a PV system having upright, in particular bifacial, PV modules and to substantially avoid shading of the PV modules, a supporting structure which is simple to manufacture and install is provided, that is constructed by vertical posts, which are connected to one another at intersecting points, and horizontally running cross-members such that rectangular mounting areas are provided for the individual PV modules. The posts and cross-members are formed in a material-saving manner by conventional profiles, and a division of the posts into two interconnectable sections substantially facilitates the assembly. An electrical connection is provided such that active surfaces which are arranged one above another can be operated at different electrical operating points and such that electrical lines are formed which are operated separately from one another and are arranged in a horizontally running manner. This minimizes effects of shading of PV modules on the efficiency of the energy conversion.

A mounting device including a base having an open bottom, a longitudinal axis, and a linear guide on the base. The linear guide guides support hardware in linear movement along the longitudinal axis. An internal cavity is under the base for containing a sealant against and in cooperation with a roof when the mounting device is secured to the roof. An opening is though the base is for receiving a fastener when the mounting device is secured to the roof. The opening is in communication with the internal cavity. The linear guide extends beyond the internal cavity.
