A repositionable roof clip assembly may include a mounting block including: a first wall, a second wall, a top wall joining the first wall and second wall and creating a gap therebetween; and at least one cable clamp including: a lower guide, an upper guide; and a bendable member joining the lower and upper guides and can be bent over a heating cable such that the heating cable is trapped between the upper guide and the lower guide.

A clamp sleeve, including: a body and a first fastening assembly. The body has first and second ends, and includes a receiving portion therein. The receiving portion has first and second openings at the first and second ends. The body is provided with a gap, the gap has two ends extending to the first and second openings, and the gap is communicated with the receiving portion. The body is provided with first extending portions at two sides of the gap along a longitudinal direction, the first extending portions is provided with a first connecting sheet near the first opening, and the first connecting sheet is connected to each of the first extending portions and connected with the first opening. The first connecting sheet is provided with a first thin thread intersecting with the gap. The first fastening assembly is disposed on the first extending portions.

The present document relates to retention collars for use with weight plates and a cylindrical element, such as a barbell, designed to receive the weight plates. The retention collar comprises a body with an expansion opening, and an opening mechanism. The opening mechanism comprises a first radial tab extending from the body adjacent to a first side wall of the expansion opening and a second radial tab extending from the body adjacent to a second side wall of the expansion opening with a tab-receiving aperture for receiving the first radial tab therethrough. When the first and second radial tabs are squeezed together, the diameter of the center aperture increases to receive the cylindrical element therethrough. When the opening mechanism is released, the center aperture returns to its original diameter and retains the weight plates on the barbell.

A positioning structure adapted for installing and fixing at least two storage devices having different sizes is provided. Each storage device has a plugging end and a fixing end. The positioning structure includes a casing, a socket disposed on the casing, at least two position-limiting components protruding from the casing, and a fixing bracket detachably engaged with any one of the position-limiting components. The plugging end of each storage device is adapted to be plugged into the socket. The position-limiting components respectively keep a first distance and a second distance greater than the first distance from the socket. According to the size of the storage device to be installed, the fixing bracket is engaged with the position-limiting component keeping the first distance from the socket or the position-limiting component keeping the second distance from the socket to fix the fixing end of the storage device to the fixing bracket.

A method of additively manufacturing a fire and overheat detection system (FODS) clamp onto a rail tube is provided. The method includes building a base of a clamp body on the rail tube, sequentially building portions of a locking feature and holders of the clamp body on the base and sequentially building remaining portions of the holders and flanges forming grooves at each of the holders of the clamp body on the base.

A tailsitter aircraft includes an airframe having first and second wings with first and second pylons extending therebetween, a thrust array attached to the airframe, payloads and payload saddle assemblies coupled to the pylons each configured to secure a respective payload. The thrust array includes propulsion assemblies configured to transition the airframe between a forward flight orientation for wing-borne lift and a VTOL orientation for thrust-borne lift. Each payload saddle assembly includes a latch assembly and a retainer configured to secure the respective payload against a respective pylon. A latch assembly is movable between various positions including an open position and a closed position and is configured to secure the respective payload in the closed position and release the respective payload in the open position. Each latch assembly is configured to move from the closed position to the open position to release the respective payload in the VTOL orientation.
