Abstract:
An adhesive member includes: a first pin portion to be inserted into a first hole formed in a first adherend member; a second pin portion which is to be inserted into a second hole formed in a second adherend member to be adhered to the first adherend member, and is formed coaxially with the first pin portion; and a flange portion which is formed using an adhesive, and is mounted to a side surface of the first pin portion or a side surface of the second pin portion in a flange shape.
Abstract:
A method includes a rotation locking step during which the rotation of the threaded hub about the central axis is blocked by heating a portion of the plug to soften, then by forcing the softened thermoplastic material to penetrate into, and then solidify in, a female cavity hollowed in the wall of the orifice to constitute a male member which fits into the female cavity. The female cavity forms, against the action of the male member, a guiding end stop preventing the male member, and therefore the hub, from rotating about the central axis to oppose any rotary screwing/unscrewing of the plug and maintaining a degree of freedom in axial translation along the central axis of the male member within the female cavity, so as not to impede a sliding of the hub and of its screw thread along the central axis against the wall.
Abstract:
Hydraulic expansion chuck with a basic body, with an expansion bush which is received in the basic body and defines a reception space for a tool to be clamped, and with a pressure chamber which is delimited between the expansion bush and the basic body. A securing pin extends through the basic body and the expansion bush into the reception space. Also broadly contemplated herein is a method for producing a hydraulic expansion chuck via: providing a basic body with a blind hole, into which an internal thread is cut. An expansion bush is then soldered into the basic body. Finally, an orifice is made at the bottom of the blind hole and extends through the material of the expansion bush into a tool reception space which is delimited in the expansion bush.
Abstract:
A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with an internal cavity. The cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. The potting compound in one portion of the cavity is typically transitioned to a solid at a more rapid rate than other portions. Once the potting compound in one portion of the cavity has transitioned sufficiently to hold the filaments at the desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.
Abstract:
A hot water storage device having a vessel includes a first section formed from a moulded material and a second section formed from a moulded material. An open end of the first section is sealingly engaged with an opposing open end of the second section to form the vessel. The first and second sections each have a generally cylindrical body portion and a closed end, comprising a head portion. The vessel includes a water inlet aperture moulded into the first or second section and a water outlet aperture moulded into the first or second section and wherein the inlet and outlet apertures are located on the body portion proximal to a tangent line between the body portion and the head portion.
Abstract:
Mechanically attaching articles made from composites has problems due to the difference in properties of the composite in the x, y planar direction and the z perpendicular direction, this results in different properties between the composite and the attachment member such as differences in coefficients of thermal expansion which can weaken the joint further leading to differences in moisture uptake which can further reduce the strength and robustness of the joint. The invention relates to the selection of the position of a joint in order to reduce such problems and to operating the moulding process in a way that improves the provision of mechanical attachments such as bolt holes.
Abstract:
A fastening element for positive, materially integral and/or non-positive arrangement on or in a fiber composite component includes a sleeve-like portion, on the first end of which there is formed a tapering conical or cone-shaped portion in which a plurality of slots are made which are aligned in the direction of a longitudinal extent of the fastening element and in this way subdivide the conical or cone-shaped portion into individual segments. On the second end of the sleeve-like portion, there is arranged a holding portion which is angled at a right angle from the sleeve-like portion and in this way enlarges an outer diameter of the sleeve-like portion and forms planar bearing surfaces. A method is also described for mounting a fastening element.
Abstract:
Electromagnetic induction welding of plastic pipe distribution systems including inter alia induction weldable pipe connectors each having at least one induction weldable pipe socket. The induction weldable pipe sockets include a solid metal susceptor sleeve enveloping a plastic solder lining. Electromagnetic induction coil assemblies for clamping on induction weldable pipe sockets.
Abstract:
An adhesive bolt for forming a fastening point to a workpiece has a head and a shank connected to the head. The shank is set up to be introduced into a cutout on the workpiece. An adhesive is situated in the region of the shank and the workpiece. The shank is configured to enter into a non-positive preliminary connection with a bounding face of the cutout until the adhesive has hardened.
Abstract:
A hydraulic expansion chuck includes a basic body, an expansion bush which is received in the basic body and defines a reception space for a tool to be clamped, and a pressure chamber which is delimited between the expansion bush and the basic body. A securing pin is provided, which extends through the basic body and the expansion bush into the reception space. A method for producing a hydraulic expansion chuck is disclosed. First, a basic body is provided with a blind hole, into which an internal thread is cut. Then, an expansion bush is soldered into the basic body. Finally, an orifice is made at the bottom of the blind hole and extends through the material of the expansion bush into a tool reception space which is delimited in the expansion bush.
