An anchor platform assembly for anchoring an object to a raised, generally flat roof-like structure, has an anchor baseplate having a top surface and a bottom surface, and an internally threaded blindbore extending at least partially from the top surface generally towards the bottom surface and fasteners for fastening an object to the anchor baseplate via its blindbore and for fastening the anchor baseplate to a top surface of a roof-like structure. The assembly is especially intended for supporting, e.g., glass railings on balconies terraces and flat roofs and for mounted solar panels on both flat and pitched roofs which provides strength and affords watertight performance.

A bus bar assembly includes a bus bar formed of a first electrically conductive material having a planar contact portion. The bus bar defines a first bore extending through the contact portion. The bus bar assembly further includes a contact insert formed of a second electrically conductive material that has a greater hardness than the first electrically conductive material. The contact insert defines a first surface that is mechanically and electrically connected to the contact portion of the bus bar. The contact insert defines a second surface this is plated with a third electrically conductive material which is different than the second electrically conductive material. The contact insert defines a smooth second bore coaxial with the first bore and extending from the first surface to the second surface.

The neck flange 3 of a tracheostomy tube is of a soft plastics such as silicone and has neck tie or suture openings 35 at opposite ends reinforced to prevent damage to the flange. The openings are reinforced by tubular inserts 38 of a harder plastics. The patient end of each insert has an enlarged, radially extending head 41 sitting flush in an enlarged recess 43 around the patient end of each opening. The opposite end of each insert also has an enlarged head 42 overlapping the flange but formed after the insert has been inserted in the flange. The opposite end head 42 may be heat formed from the end of the insert or may be a separate component clipped onto the end of the insert.

A cast-in insertion member out of which a core inserted during casting of cast portion can easily be pulled, and production method thereof are provided. Inside covering portion is formed to cover the interior of one end of pipe. During the casting, inside covering portion is interposed between the inner surface of the one end of pipe and the outer surface of the tip of the core put into pipe, so that a bite between pipe and the core by contraction of pipe due to molding shrinkage of cast portion can be prevented. Inside covering portion includes tapered surface on the side of recess, which gradually widens from the one end to the other end of pipe. After molding of cast portion, tapered surface making contact with the outer surface of the tip of the core gradually widens in the direction opposite to that of putting the core into pipe.

A metal corner connector contains at least two connection regions which are arranged on a lateral surface of the metal corner connector. At least one connection region is configured to be mechanically stably connected via welding to a metal pipe extending along a main extension plane of the metal corner connector. The connection region contains at least one protrusion with a groove, which is configured for receiving a welding material. The connection region has an outer surface which is adjacent to the protrusion and is configured as a contact surface for an end face of the metal pipe. A method produces a device having such a metal corner connector.

There is provided a method for non-penetration joining of members. The method includes: keeping a joining member having a protruding part by a receiving mold so that the protruding part is exposed; placing a joined member over the joining member so that the protruding part of the joining member is positioned in a blind hole of the joined member, and compressing the joined member against the receiving mold to plastically deform the joined member and the joining member at the same time and to wrap excess thickness of the joined member around an undercut part while forming the undercut part on the joining member, thereby non-detachably joining both the members.

A method for connecting or joining a first substrate and a second substrate across an interface between the first substrate and the second substrate. The method includes disposing a fastener precursor in the bore and sintering the fastener precursor in the bore. The fastener precursor densifies and shrinks in at least one dimension to mechanically interlock with a contour in the bore and form a mechanical fastener in the bore, and the mechanical fastener forms an interlock between the first substrate and the second substrate.

A nozzle device according to some embodiments includes an annular nozzle plate, an annular nozzle mount defining a nozzle flow passage between the nozzle mount and one surface of the nozzle plate, at least one nozzle support coupling the nozzle plate and the nozzle mount, and fixed to at least the nozzle plate by caulking, and at least one nozzle vane supported between the nozzle plate and the nozzle mount. The nozzle plate has a through hole into which an end portion of the at least one nozzle support is inserted. The through hole includes a straight portion extending from the one surface toward another surface of the nozzle plate, an enlarged diameter portion formed on a side of the another surface of the nozzle plate and having a larger diameter than the straight portion, and a relief processing portion which is formed in a part of the straight portion continuing into the enlarged diameter portion and has a larger diameter than another part of the straight portion where the relief processing portion is not formed.

A bracket for a rotating shaft includes a base and a retainer assembly. The base has a mount body and a receiver, first and second tabs extending from receiver and overlapping spaced apart portions of the mount body. The retainer assembly has a first retainer and a second retainer that overlap the tabs and trap the tabs against the mount body to hold the receiver on the mount body, and the first retainer overlaps part of the second retainer and the second retainer overlaps part of the first retainer to maintain the positions of the retainers relative to the mount body and receiver.
