  • Publication number: 20210044033
    Abstract: A bolt terminal mounted on a guide rail is provided. The bolt terminal comprises a housing (1), an integral nut (2), a screw (3), a connection component (4), and a wiring metal surface (5); one end of the screw is provided in the housing, the other end of the screw is located outside the housing, and the screw located outside the housing is to be connected to the integral nut fitted therewith; the wiring metal surface is provided on the interface between the screw and the housing; and the housing is to be connected to the guide rail via the connection component. The bolt terminal increases the requirement for powering the wirings, and the bolt terminal can be removed from the guide rail only by using a conventional screwdriver to lightly tap on a removal port. The screw is integrally connected to the housing by injection molding and thus there is no risk of the screw falling off, enabling higher reliability.

  • Publication number: 20200296903
    Abstract: A soil bed covering and planting apparatus is adapted to be carried along the length of a soil bed by a conveyer vehicle and includes a cover material reel configured to retain and supply a sheet of cover material, and a compaction roller configured to feed cover material over a soil bed and to press the cover material onto the soil bed. Two spike hammers are positioned adjacent to and at opposite sides of the compaction roller, each being configured to drive at least one spike through the cover material into the soil bed. An actuation structure is associated with each spike hammer and urges the spike hammer against a spike. A piercing assembly forms a series of holes in the sheet of cover material and engages with a drive structure that reciprocates the piercing assembly to drive one end of the piercing assembly through the sheet of cover material.

  • Publication number: 20200129425
    Abstract: Methods and compositions for systemically or locally administering by implantation a beneficial agent to a subject are described, and include, for example, depot gel compositions that can be injected into a desired location and which can provide controlled release of a beneficial agent over a short duration of time. The compositions include a low molecular weight biocompatible polymer, a biocompatible solvent having low water miscibility that forms a viscous gel with the polymer and limits water uptake by the implant, and a beneficial agent.
