A wall hole punch device is provided. The punch device has a wall-engaging surface, a floor-engaging surface, and a punch. The punch has a punching end, which generally has an angled face for pushing the chad downwardly and away from the hole. The bottom of the punching end is high enough to clear typical base plates when the punching device is used as intended. The top of the punching end is low enough so that the hole can be covered by baseboards of conventional height. A method of punching holes in walls and a method of drying walls using the device are also provided.

An eye model comprises a sclera simulation that comprises a bright plastic material, the plastic material comprising a polyvinyl chloride at least as the main component. The eye model also includes a pattern that contrasts in color with the sclera simulation, the pattern simulating an eye pupil and/or an iris structure. In a method for producing the eye model, a plate-shaped or rectangular blank of the plastic material having two oppositely situated blank flat sides is used, from which an eye body is separated by cutting or chipping machining. The separated eye body has a flattened area that is formed from a first blank flat side, and a convexly curved peripheral surface that surrounds the flattened area in a ring-like manner.

A reveal edge tile cutting apparatus is provided for. The reveal edge tile cutting apparatus has a tray with a top surface and a bottom surface, as well as a first set of tracks and a second set of tracks. Attached to these tracks is a vertical cutter featuring two cutting wheels, a horizontal cutter featuring a separate cutting wheel. A measuring device may be located on the top surface of the tray.

A clamping assembly includes a first jaw having a plurality of alternating grooves and lands formed thereon, a second jaw having a plurality of alternating grooves and lands formed thereon, and a spring provided between the first and second jaws. The jaws are pivotable relative to each other. The jaws are attached to a draw stud. The draw stud is formed from an elongated cylinder which has a conventional thread form formed on one end thereof and a plurality of alternating grooves and lands formed on the other end thereof. The alternating grooves and lands formed on the jaws mesh with the alternating grooves and lands formed on the draw stud to mate the jaws with the draw stud.

A fabric circle cutter having a cutter base, a pivot pin assembly, and a blade assembly. The cutter base has a flat, smooth bottom surface with a turned up edge. The cutter base also has a raised base section which has a pivot point slide slot. The pivot pin assembly is slidably mounted on the raised base section and slidably mated with the pivot point slide slot which provides for selective positioning of the pivot pin assembly. The blade assembly has a rotary blade with a blade axis which is aligned approximately horizontally with and approximately parallel to the center line of the pivot point slide.

A cutting data generator includes a control device configured to obtain provisional hole arrangement data usable to arrange a plurality of provisional holes and to obtain an intercentral distance between two of the provisional holes. The provisional holes are adjacent to each other. The control device is also configured to connect the provisional holes with an auxiliary hole and to determine that the provisional holes and the auxiliary hole are contained in a group, thereby extracting an outermost outline of the group of the provisional holes arranged, when the intercentral distance between the provisional holes is not less than a sum of radii of the provisional holes and not more than a predetermined value. The control device is further configured to generate cutting data usable to cut the sheet along the outline extracted. The auxiliary hole having a smaller diameter than the provisional holes.

Disclosed is an optical fiber processing apparatus comprising: an optical fiber machining head provided with a fiber proceeding tunnel, through which an optical fiber passes, and a plurality of processing rod insertion holes formed in the circumference of the proceeding tunnel in a direction perpendicular to the tunnel; a processing rod having a machining tip for processing the optical fiber in the proceeding tunnel through the processing rod insertion hole; and an actuator operating a processing drill.

Described herein are devices and methods of use thereof for preparing ostomy bags for attachment to a stoma. The device can include an elongated housing, a cutting tool including a blade, and a measurement guide for measuring the diameter of a stoma, each of the cutting tool and the measurement guide surrounding a given portion of the elongated housing. The device can include a handle that comprises a pinion operably coupled to each of the cutting tool and the measurement guide by racks, such that engaging the handle causes each of the cutting tool and the measurement guide to translate along the elongated housing. The device can include a cutting base that is coupled to the elongated housing such that the cutting base is insertable into an opening of an ostomy bag and receives the blade of the cutting tool when cutting an adhesive portion of the ostomy bag.
