Abstract: A fastener system with a coaxial annular flange (14) having through holes (16), each serving to pass a screw (17) for screwing into an associated tapped hole (16) in the wall (2) of a stationary structure. Each through hole (16) has a circularly cylindrical distal segment (16a) followed by an enlarged proximal segment (16b) adjacent to the wall (2) of the stationary structure, allowing the shank (19) of the screw to bend and enabling a corresponding lateral offset (D). This prevents the screw (17) rupturing under high shear forces due to accidental destruction of a vacuum pump rotor while rotating at full speed.

Abstract: A barrier, such as fence panel, is formed from a plurality of channel-shaped rails and plurality of upright members. Each upright member traverses the rail channels of the rails forming the barrier and is mechanically connected to the rail, such that the upright member is selectively tiltable with respect to the rail within an angular adjustment range. The mechanical connection between rail and upright member may be formed by a weld, such as a resistance weld, by a permanent adhesive, or with a fastener such as bolt or screw. A tab that extends from the rail web may be used to connect a rail to an upright member. The tab may depend from a bracket installed within the rail channel, or may be cut out and bent into the channel from the web. The tab is rotatable about an axis situated at or adjacent the web.

A first step part swelling to the hub tooth part is formed in the bottom part of the shaft tooth part, and a second step part recessed in a direction opposite to the shaft tooth part is formed in the ridge part of the hub tooth part. The start point of the first step part and the start point of the second step part are set at positions offset by a specified distance from each other.

Abstract: The system incorporates wire deflection, taut wire detection for perimeter security applications. Generally, the system of the invention provides intrusion detection by an internal mechanism. The internal mechanism can detect wire deflection in any direction. In turn, given a sufficient amount of wire deflection, a security system is signaled. However, the force required to sufficiently deflect the wires is high enough so as to minimize nuisance alarms. The internal mechanism is generally held within a structure so that it is protected from tampering. As such, the internal mechanism is also kept separate from the wire array so that it is protected from attempts by an intruder to isolate the wire array.

Abstract: A turnlock fastener (1) for the connection of two components features a cover plate (4) and a base shaft (5) which is formed on the cover plate (4) and which extends away from the cover plate (4), at which at least two opposing rigid locking stands (10, 11) are positioned at a distance from the cover plate (4) and extend outward from the base shaft (5) in the radial direction. In addition, a fixing arrangement is provided to secure the turnlock fastener (1) to a first component which possesses at least two radial elastic spring limbs (14, 15) which are each arranged between two locking stands (10, 11) and which are connected at one end with the base shaft (5) and which extend away from the base shaft (5) with the other free end in the direction of the cover plate (4). That way, the turnlock fastener (1) can be secured ahead of time within certain relatively large dimensions of insertion openings of different sizes and with relatively large pullout forces.

Abstract: A connection joint (20) is described that is formed by inserting a plastic connector (10) into the end of a silicone tube (14). The connector includes a plurality of barbs (12). A reinforcing agent (16) is placed between each of the barbs (12) of the connector (10). An adhesive (18) is injected between the tube (14), the reinforcing agents (16) and the connector (10). The adhesive (18) is then cured at a predetermined temperature for a predetermined time in order to solidify the connection joint (20).

Abstract: A net/fence includes retro-reflective elements such as tapes that extend in horizontal and/or vertical directions with respect to the fence. The tapes are attached to the netting by thread or glue. One method for weaving the net/fence includes dragging the tape extending in a machine direction along the netting during weaving and threading the tape thereto. Another method for weaving the net/fence includes dragging the tape extending in a transverse direction and attaching the tape thereto with glue. A net-weaving machine can produce such a net in a machine direction and use a comb having threading needles to selectively attach the tape to the net with the thread. If attached in the transverse direction, a trolley borne on a beam lying in the transverse direction introduces the tape onto the net and a connection device, such as a glue jet, connects the tape to the net.
