A barbed suture is provided. The barbed suture includes an elongate body and at least one barb extending from the elongate body. The elongate body defines a recess adjacent the at least one barb. Also provided is a method of making a barbed suture. The method includes the steps of providing a suture nest and a punch apparatus configured for operable engagement with the suture nest, loading a suture through the suture nest, engaging the punch apparatus with the suture nest, and disengaging the punch apparatus with the suture nest.

An apparatus and method for distressing material, such as a board. The apparatus may include a cutter head supporting a blade, a guide member, and a flattening device. The flattening device and the guide member are positioned proximate the cutter head and on opposite sides thereof. In response to the cutter head and the surface of the material being brought into cutting contact and moved relative to each other, a resulting portion of the surface of the material is distressed. The flattening device maintains the proper vertical position of the cutter head and blade relative to the material and a material support as the material is being brought into cutting contact with the cutter head. The guide member levels warped material boards thereby bringing the board into proper elevation and engagement with the blade for cutting or scraping a top surface of the board. The material may be wood.

A barbed suture is provided. The barbed suture includes an elongate body and at least one barb extending from the elongate body. The elongate body defines a recess adjacent the at least one barb. Also provided is a method of making a barbed suture.

The present invention relates to an object comprising a region of its surface suitable for showing a plurality of images. Each of these images is observable from a different direction such that upon observing one of the images the other images stop being observable and do not interfere in the viewing of the observed image. The configuration which allows generating the region of surfaces suitable for showing the plurality of images allows for mass production by means of stamping or minting techniques and complicates the reproduction by unauthorized manufacturers. A method which allows obtaining the object having a region suitable for showing a plurality of images is also an object of the present invention.

The present disclosure relates to a punching device for punching network nodes on a mold insert, comprising: a first horizontal guide rail, a mounting seat, a first driver, a punching mechanism, a laser distance meter, a host computer, a displacement operation controller, and a work platform, wherein the laser distance meter is configured to measure at least one of thicknesses and hole diameters, spacing between the network nodes, and flatness of the mold insert, the displacement operation controller derives an appropriate value of electrical current from measurement results of the laser distance meter and sends it to the host computer, and the host computer supplies electricity to the electromagnetic mechanism in accordance with the value of electrical current, so as to perform an operation of punching the network nodes. In addition, it also relates to a method of punching network nodes on a mold insert using a punching device.

A nail gel/acrylic removal system and method for manufacturing a roll of foil segments with pads around a core used for nail gel and acrylic nail removal. A pad is configured to receive and absorb a substance for dissolving at least one of nail gel and acrylic nails. A segment of foil with an affixed pad is sized to wrap around at least a portion of a finger of a human hand so that the pad with the substance for dissolving is in contact with a fingernail of the hand. First and second sets of perforations are placed along opposite edges of the foil segment, so that pairs of foil segments with the pads are joined at the first and second set of perforations. A roll is formed of the foil segments with pads around a core.

A bar of a support structure for a false ceiling is described. The bar has an elongated shape along a longitudinal direction and includes at least two sheet metal portions located side by side or overlapped, in contact or adherent, with each other along said longitudinal direction, or short side direction. In the bar a transverse direction, or short-side direction, extending transverse to, or intersecting, said longitudinal direction is defined. At least one of the sheet metal portions has cuts defining partially cut parts, wherein a partially cut part of said at least one of the sheet metal portions protrudes towards the other of said sheet metal portions in a thickness direction so as to determine an interference of parts in the thickness direction. The cuts are arranged, are directed, or extend along said transverse direction and the partially cut parts have, when viewed in perspective, an at least partially curvilinear or concave profile.

A balance correction sheet corrects a whole pressure balance of a punching machine, in which a punching die and a cutting plate for receiving blade tips of the punching die are attached to be opposed to each other. A method of forming the balance correction sheets includes attaching a balance correction die having a plurality of punching blades disposed at a predetermined interval to the punching machine, intermediately inserting the blade tips of the punching blades into a middle of laminated sheets formed by laminating peelable sheets so that incisions are formed in a depth direction of the laminated sheets, and partially removing the laminated sheets depending on depths of the incisions so as to prepare the balance correction sheet.

An accessory unit for use with an electronic device is described. Accessory unit includes a front flap and a rear cover. The rear cover includes a recessed portion that defines a chamber and a lip portion. The chamber is configured to receive a consumer electronic device, and the lip portion is configured to hold the consumer electronic device therein by an interference fit that exposes substantially all of a display portion of the consumer electronic product. The front flap can include segments formed from panels with folding regions therebetween, which allow the front flap to fold. Further, an end region of the front flap pivotally couples the front flap to the rear cover, such that the front flap may be moved between open and closed configurations. The front may include magnetic elements.
