A method of making a barbed suture by varying the blade geometry and / or the movement of the blade when cutting a suture. The method can also be accomplished with a cutting device to create a plurality of barbs on the exterior of surgical suture. The barbs produced using the method with the cutting device can be the same or random configurations.

Razor wire which includes a core wire, an electrically insulating sheath over the core wire and a strip, with a plurality of barbs, which is crimped, along two lines, on opposing sides of the sheath, positioned so that the sheath is not damaged during the crimping process.

The invention comprises of a method and alarm device used to prevent metal theft from irrigation systems. The alarm device attaches to a plurality of electric conductor such as copper wiring that is in need of protecting and the preexisting irrigation system circuit. The alarm device detects voltage in the irrigation system circuit and if there is no voltage signals from the irrigation system circuit, then the alarm device automatically breaks the original circuit and inserts itself into the irrigation system circuit. The alarm device then sends a low voltage, low current down the plurality of electric conductors and the plurality of conductors then become part of a circuit that energizes a magnetic switch located in the alarm device. A breach of integrity of the plurality of conductors such as by physical detachment triggers an alarm condition which lead to audio and visual alarms plus activating an automated dialer.

Apparatus for dispensing coiled barb tape which includes a frame in which is located a boom from which the coiled barb tape is suspended. The boom is extensible to assist in deployment of the barb tape and the frame, apart from protecting the coiled barb tape, provides a stacking characteristic with similar frames.

A cooling fan 17 is arranged on the rear side of a twisting motor 9 of a reinforcing bar binder 1. The cooling fan is located on the axial line of the twisting motor so that cooling air effectively flows along the surface of the twisting motor and through within the twisting motor. A control unit on-off controls the cooling fan according to the temperature detected by a heat sensitive element 23 so as to actuate the cooling fan when a trigger signal is received at an interior temperature not lower than a reference value and to stop it after a predetermined time elapses. Thus, the temperature of the reinforcing bar binder can be controlled within a safe temperature range. Even if the reinforcing bar binder is run during a long time, a protecting circuit is not operated to forcibly stop the reinforcing bar binder. Further, in a cold environment, the cooling fan is not actuated so that the performance at a low temperature is not deteriorated and so power consumption can be also saved.

A security fence for swimming pools is provided to be so positioned as to surround the water of a swimming pool. The security fence comprises fence sections which are linked to an alarm system. The fence sections are moveable between a non-signaling position and an alarm signaling position. When the fence sections are in the non-signaling position and a given fence section is engaged with sufficient force it is moved to the alarm signaling position thereby signaling the alarm. The foregoing prevents a user, such as a child, from entering the pool water when the alarm system has been activated.

An anti-scaling device comprises a hollow central body for mounting on a bar and several spike units extending outwardly from the body in different directions. Pairs of spike units are rotatably and preferably detachably mounted on opposite sides of the central body. The device may further comprise serrated webs extending outwardly from the central body between the spike units. The device may also comprise rows of sharp-edged teeth axially aligned along the central body. Alternatively, the spike units may be partially rotatable serrated propellers or may be pivotably rotatably mounted. The device may be moulded from plastic material.

An antipersonnel barrier system includes at least one concertina coil and a plurality of spaced support members. Each of the support members includes a base section and a vertical section. Each of the concertina coils is secured to the support members to provide a horizontally and vertically stabilized barrier. A length limiting cable is provided to limit the length of spacing between adjacent support members. The support members can include anchoring structure for securing the support members to a support surface. In one embodiment, the concertina coils include two small diameter base coils and a top coil positioned on the base coils.

A barrier structure includes a continuous piece of elongated metal tape. The metal tape includes barbs spaced along an elongate body. Each of the barbs is connected securely to a barb root, and each barb root is connected securely to the elongate body. A first region of the elongate body is adjacent to each barb root, and a second region of the elongate body is adjacent to each first region distal from the barb root. A third region of the elongate body adjacent to each second region distal from the first region extends lengthwise from each second region and meets a corresponding third region that is extending lengthwise away from another second region. Each second region extends transversely and inwardly from the adjacent first region and the adjacent third region.

A system for forming one or more barbs on a length of suture is provided. The system includes a suture nest and a punch apparatus. The suture nest defines a longitudinal passage configured for receipt of a length of suture. The suture nest includes at least one recess formed along the longitudinal passage and at least one opening corresponding to the at least one recess. The punch apparatus includes at least one punch member corresponding to the at least one opening in the suture nest. The at least one punch member is configured to be selectively received within the at least one opening in the suture nest.

The present invention provides a fencing system having interconnected tubular elements comprised of longitudinally extending conductor wires and reinforcement wires. Said conductor wires are conventionally disposed in an outer casing's cavity with an open round or rounded section. Said outer casing is formed by a crimping process such that said conductor wires are reinforced by parallelly extending reinforcement wires, the latter wires being disposed in a separate partition of the longitudinal inner volume of said outer casing. Said partition assigned to said reinforcement wires provides that said reinforcement wires does not damage said conductor wires during the final stage of crimping process in which barbed tapes with pointed and / or cutting barbs are transversely folded around the interconnected tubular elements.

A station for cutting a barb suture is provided. The barb cutting station includes a suture transport assembly for supporting a first suture, a first knife assembly for forming barbs on the first suture, and a first clamp and position assembly for approximating the at least first suture towards the at least first knife assembly. The barb cutting station may further include at least a first suture cutting mechanism configured for severing the at least first suture when a defect is detected. The station may also include at least a first visual inspection assembly configured for detecting defective barbs.
