Abstract: Devices, kits and/or methods for, or related to, creating a plurality of openings in a skin graft or skin substitute are described. The devices can have a plurality of perforating elements extending from a perforation component that can be safely held and manipulated by a user. The user can apply sufficient force to the perforating elements against the skin graft or skin substitute to enable the extended ends of the perforating elements to pass through the skin graft or skin substitute as to create openings therethrough.

Abstract: A continuous machining device includes: a film machining mechanism that forms a hole in a film; a holding mechanisms being provided integrally with the film machining mechanism; a slider that supports the film machining mechanism and the holding mechanism in a reciprocative manner relative to a feeding direction of the film; and a return mechanism that returns the film machining mechanism and the holding mechanism to their respective original positions defined on the opposite sides to the feeding direction of the film. When the film is held by the holding mechanism, the film machining mechanism can be moved in synchronization with the film. Thus, after the hole is formed in the film by the film machining mechanism, the film machining mechanism and the holding mechanism can be returned to their respective original positions by the return mechanism as soon as the film is released from the holding mechanism.

Abstract: A perforation apparatus, having: a perforation device to perforate a sheet by a punch; a pair of aligning members to align the sheet in a sheet width direction; and a contact member to contact with an trailing edge of the sheet, capable of being inserted and retracted with respect to a conveyance path of the sheet, disposed at an upstream side of the punch in the sheet conveyance direction; wherein the sheet is moved and aligned to a sheet aligning position while being grasped by the aligning members, the aligning device is retracted from the sheet aligning position after the aligning operation is completed, subsequently the contact member pushes the trailing edge of the sheet and conveys the sheet to a predetermined position, then the sheet is perforated by the perforation device.

Abstract: A system and method are provided for creating tabs from regular cut-sheet stock after printing by partially punching out a section of a sheet and folding the punched out section back on itself at the remaining side. The location of the punched out section is such that when folded back, a portion of the punched out section sticks out beyond the border of the original paper size. Tab labels may be printed on the back side of the sheet so that when folded out, the tab label is in the correct orientation, i.e., facing front on the folded out tab. The punch head, which is used to punch out the section of the sheet, may be oriented flexibly and moved outboard or inboard. Tabs may be cut and folded to produce a readable set of tabs along any of the top, bottom, lead or trail edges of a sheet.

Abstract: An adapter for mounting on drug vial of various sizes to provide needleless access to the interior of each vial regardless of its size. The adapter includes sharpened cannula surrounded by peripheral sidewall. The peripheral sidewall includes an upper portion and a lower skirt flaring outward from the upper portion and terminates in a peripheral free edge extending beyond the sharpened end of the cannula to protect users from an accidental needle-stick. The sidewall includes plural equidistantly spaced projections extending radially inward to form a ledge also has slits extending upward from the peripheral edge of the skirt to enable portions of the sidewall including the projections to flex outward. By so doing the cap of the vial is enabled to pass between the projections and then return to a position wherein the ledge has inside diameter just slightly less than the outside diameter of the rim of the cap to releasably secure the adapter to the vial with the cannula piercing through the septum of the cap.

Abstract: The music roll perforating system permits a paper music roll to be perforated from a special previously prepared magnetic tape containing a digital recording of a music rendition. The process and apparatus disclosed uses a small computer to drive a music roll perforator through a driver box. The driver box accepts a serial data stream from the computer and converts it into parallel channels with high current/high voltage outputs capable of driving the solenoids used in a conventional music roll perforating machine.A magnetic tape recorder is attached to the computer for the dual purpose of either loading a computer program into the computer following turn-on or for reading the specially prepared digital recording into a computer memory. A Teletype machine is also attached to the computer to permit input to the computer from an operator.

Abstract: A punching, reading and printing machine for document cards having a hopper holding the cards in vertical disposition, card transporting means moving the cards out of the hopper into horizontal disposition in a horizontal card path and closely spaced punching, reading and printing mechanisms operative on the cards while in the horizontal path. The punching mechanism includes a row of punches extending transversely of the card path each made active by an interposer and a leaf spring actuator for the interposer, and the printing mechanism includes a row of print hammers extending longitudinally of the card path and an electromagnet and armature for each of the print hammers. The interposer springs extend longitudinally of and over the path of card travel preceding the punches, and the armatures extend transversely of the machine for shortening the machine and rendering it more compact.

Abstract: An apparatus for swaging the movement control belts for controlling the operational groups of a knitting machine comprising a punching bar, a die, punches, a punch bearing plate, entrainment means, a movement control belt, punch selection means, and a selector keyboard.
