Abstract: An apparatus and method for making a custom shim for a die component having one or more blind holes, where the apparatus includes a preformed laminate having an adhesive layer, a protective layer removably attached to one side of the adhesive layer, and a paper impression layer attached to the opposite side of the adhesive layer. The method includes the steps of removing the protective layer from the adhesive layer, attaching the exposed adhesive layer to a piece of shim stock, applying ink to the surface of the die component having the blind hole(s), placing that surface of the die component on the paper layer to form thereon an ink impression of the die component, removing the die component from the paper layer, cutting the piece of shim stock in accordance with the ink impression, and removing the laminate from the cut shim stock to uncover the custom shim which accurately maintains the relationship between the blind hole and the outer contour of the die component.

Abstract: A secondary seal in the form of a plug member insertable in the open end of a pneumatic discharge nozzle of a covered hopper car carrying granular material, such as plastic pellets, wherein the plug member includes means for maintaining the pellets in spaced relation to the open end of the nozzle to prevent spillage when the plug member is removed, and having retaining means connecting the plug member to the nozzle when it is removed from the open end of the nozzle.

Abstract: An improved plastic knuckle pin for a coupler on a railway car and a method of making the improved plastic knuckle pin whereby the improved plastic knuckle pin has a substantially uniform material matrix and the method of making the pin increases uniformity in the material by increasing the surface cooling area which decreases air and moisture pockets in the material during the molding process.

Abstract: A buccal tube for an archwire wherein the tube includes a lumen having a control portion at the mesial end and a relieved portion toward and at the distal end which reduces the force required for mesial withdrawal of the archwire after the archwire has been bent, and may also permit distal crown tipping of the tooth on which the tube is mounted.

Abstract: A bonding pad for an orthodontic attachment to be bonded to a tooth, including a foil or plate having a photoetched surface, and a layer of mesh material diffusion bonded to the photoetched surface of the foil, thereby greatly increasing the bonding strength of the attachment to which the bonding pad is secured.

Abstract: An electronic pneumatic brake system for trains which significantly improves brake cylinder pressure build-up time and facilitates essentially instantaneous and simultaneous braking on all cars of the train. The electronic pneumatic brake system includes electronic pneumatic control valves on the cars which individually control the braking on each car or a pack of cars and which are regulated by an electronic pneumatic controller on each car that receives electronic braking and release signals by way of wireless communication from an electronic head end unit on the lead locomotive, or where no head end unit is provided in the locomotive, receives pneumatic braking signals through the brake pipe.

Abstract: A device for closing the gap between adjacent sidewall panels in an auto rack railroad car in the form of a generally H-shaped elongated plastic member grippingly engaging the panels and closing the gap to prevent the movement of air and precipitation through the gap. The device may be made as a one-piece or two-piece unit.

Abstract: An adjustable fingernail protector for protecting the paint or polish on a fingernail after a manicure, which is attached to the finger primarily ahead of the first knuckle and behind the fingernail to avoid significantly impairing the motion of the hands. The fingernail protector includes a fingernail protective shield having a supporting base and a hood, and a securing band adapted to releasably secure the supporting base to the finger to maintain the protective shield on the finger.

Abstract: Apparatus and method for prepasting orthodontic appliances such as brackets with a light-cure adhesive and facilitating the mounting of the brackets in the mouth of a patient. The apparatus includes a kit having a storage box capable of storing a plurality of bond cards on which prepasted brackets are mounted in an organized fashion, a work box for facilitating the initial mounting of the brackets on the bond cards, a bond card cover for protecting the prepasted brackets against curing of the adhesive at the chairside of the patient, and a mouth shield for delaying the curing of the adhesive following initial placement of the prepasted brackets in the mouth of a patient.

Abstract: A hole covering device attached to the sidewall panels or screens in an auto rack car to prevent the direct passage of air and air-carried contaminants into the auto rack car through the multiplicity of holes in the screens to prevent damage to the finishes of newly manufactured vehicles being transported. The hole covering device includes a non-opaque plastic covering panel which is sized and adapted to be mounted on the interior surface of the screen by a plurality of button fasteners to cover a significant number of the holes in the screen. The covering panel permits light into the car through the covering panel and does not significantly inhibit the ventilation of the vehicle exhaust gases during loading and unloading of the vehicles.

Abstract: A gap closing device for closing the air gaps between the sidewall panels and the floor and/or the gaps between the sidewall panels and auxiliary floor panels or plates in an auto rack railroad car comprising an elongated strip of flexible extruded plastic material having a spine adapted to extend through the gap, a flap centrally connected to one end of the spine for closing the gap, and fins extending from the spine to lock the device in gap closing position. The fins may include a plurality of locking and/or pressure fins.

Abstract: A brake beam wear plate for mounting in brake beam guide brackets of railroad car truck side frames having side walls of varying thicknesses to define a slideway for the brake beam lugs providing a sloppy fit and a path of movement to obtain the ideal clasping angle and alignment for the brake shoes with the wheels, and thereby produce better train handling during braking, and uniform wearing of the shoes to enhance shoe life and reduce maintenance.

Abstract: A bumper system for a movable deck in an intermodal auto carrier or trailer wherein the bumper system is mounted on the deck and is foldable against the deck or opened to a position for protecting the auto doors against damage when opening the doors for ingress and egress of a driver during loading and unloading operations.

Abstract: A twin edgewise orthodontic bracket having an engagement mechanism for retaining an archwire, comprising a base having a pair of tie wing sets with an archwire slot and a slidable locking shutter or clip which in closed position retains the archwire in the archwire slot without the need for an elastic ligature and in open position allows placement and removal of the archwire.
