To provide a post-installed anchor capable of being used repeatedly and being easily removed and recovered. A post-installed anchor to be inserted and fixed in an anchor insertion hole formed in a structure includes: a cylindrical anchor body; expandable pieces obtained by dividing the tip side of the anchor body into a plurality of pieces by a plurality of slits 16 which are formed on the tip side, leaving equal intervals in a circumferential direction and extending in the axial direction of the anchor body, the expandable pieces each having a plate-like part whose surface is formed into a flat surface and which has spring force, a fixing part formed at the tip of the expandable piece and having a larger thickness than that of the plate-like part, and an inclined part whose inner surface is gradually inclined inward toward the tip of the expandable piece; a female screw formed in an inner surface of an unexpandable part side of the anchor body; and a male screw body formed into a substantially columnar shape that can be inserted into the anchor body, having a wedge part with a truncated conical shape at its tip, having a male screw screwed with a female screw formed in the anchor body at its rear end side, and having a rotary tool engagement part at its rear end surface. The male screw body is advanced with the male screw of the male screw body screwed with the female screw of the anchor body to make the truncated conical shaped wedge part at the tip of the male screw body abut against the inclined part formed so that the inner surface thereof is gradually inclined inward toward the tip side of the expandable piece to expand the expandable piece by wedge action, pressing the outer surface of the fixing part against the hole wall of the anchor insertion hole, which thereby fixes the post-installed anchor in the anchor insertion hole, and the male screw body is retracted to close the expanded expandable piece by spring force of the plate-like part of the expandable piece for recovery and reuse.

To provide a method for readily forming an easily separable portion having an adhesive strength that is required as a package bag on packaging film, a package bag having an easily separable portion formed by this method, and a filling-packing machine utilizing this method. A method forming an easily separable portion in packaging film by interposing at least two packaging films between a horn emitting ultrasonic waves and an anvil oppositely disposed to the horn, and vibrating the packaging films by the ultrasonic waves, in which a vibratable layer is provided on the packaging film in at least one of the horn side and the anvil side.

A conductive sleeved fastener assembly includes an electrically-conductive fastener having a fastener head and a fastener shank extending from the fastener head and an electrically-conductive fastener sleeve receiving the fastener shank of the fastener and a fastener sleeve flange provided on the fastener sleeve and disposed in direct contact with the fastener head of the fastener. A method of preparing a conductive sleeved fastener for use is also disclosed.

Mobile data processing Systems (MSs) interact with systems in their vicinity, and with each other, in communications and interoperability. Graphical objects are recognized in an image field of view, for example to calculate, determine, or confirm location information.

A method for installing an anchor for the fastening of an attachment part to a base part includes arranging an anchor bolt of the anchor in a hole which is provided in the base part and in a through hole provided in the attachment part. A damper sleeve is arranged on the anchor bolt such that the damper sleeve surrounds the anchor bolt. The damper sleeve is adhesively bonded to the attachment part by adhesive.

The invention relates to a method for anchoring a joint element (1) in a metal sheet (7) so as to be secured against rotation, the hardness of the metal sheet being equal to or greater than the hardness of the material of the joint element. A locking and securing portion (4), which protrudes away from a head (2) of the joint element, is inserted into a joint opening (8), which is provided in the metal sheet and which has a cross section that deviates from the circular shape, such that an edge of the joint opening forms at least one region with a maximum distance to a central axis of the joint opening and at least one region with a minimum radial distance to the central axis of the joint opening, and the head of the joint element rests against the metal sheet after being anchored.

Rail fastening system (1) for fastening a rail (2) to a rail subsurface, preferably for a ballastless track, comprising a base plate (10), preferably made of a plastic, and at least one dowel (20), wherein the base plate (10) has at least one opening (15), which completely penetrates the base plate (10) in the thickness direction, and the dowel (20) is introduced into the opening (15), is held therein by means of a retaining contour and projects in the thickness direction at least on one side beyond the base plate (10).

A valve assembly with a multidirectional flow path includes a valve body that includes respective hinged portions defining respective passageways extending through the valve body when in a closed state. A flexible conduit or tubing having a loop portion and a plurality of branches extending from the loop portion is at least partially positioned within the valve body. Portions of the loop that extend beyond the valve body are encapsulated by respective rigid jackets. Multiple valves are situated on the valve body and are used to selectively pinch the loop portion in different pinching configurations to direct fluid to or from the particular branches. The valve assembly may be integrated into a manufacturing or other production process with optional additional jackets used to encapsulate the flexible conduit branches.

An oval-shaped T-nut that is received within an oval receiver machined into the upholstered panel to be secured to a chair frame is provided. The oval shape of the T-nut prevents the oval-shaped T-nut from rotating when a screw is driven into the T-nut. Further, this eliminates the necessity of stapling the traditional plastic T-nut to the chair panel, thus saving time and money associated with the manufacture of an upholstered metal frame chair. In addition to the oval-shaped T-nut described herein, a novel U-shaped screw catch is also provided which cooperates with a barbed nylon or plastic push rivet to secure the upholstered chair panels to one another. Further, a method for connecting upholstered seat back panels to the tabs positioned on the back frame of a chair, utilizing the T-nut and the screw catch is disclosed.
