Abstract: In a web handling apparatus for continuously supplying a running web to a web-consuming machine using a main accumulator to provide uninterrupted feed of the web during splicing of the trailing end of an expiring roll to the leading end of a ready roll, an improved ready-roll acceleration technique uses a supplemental accumulator disposed between the ready roll and the splicing head to enable the ready roll to be accelerated prior to completion of the splice. This technique permits the use of a smaller main accumulator and/or increased running speeds. In fact, the total storage capacity of the main and supplemental accumulators can be less than that of the single accumulator of conventional apparatus of this type. Furthermore, the running roll can be slowed without adverse consequence so as to reduce web tension upsets. The invention is also useful in web winder/splicer applications.

Abstract: The present invention discloses a cover for an x-ray cassette which has a sleeve made of radiolucent material to receive an x-ray cassette. A foam pad is attached to the sleeve and aligned such that the foam pad covers the x-ray cassette. The foam pad is made of radiolucent material. The sleeve is made from a first sheet and second sheet of radiolucent material attached on three sides, which create a slot and a sleeve.

Abstract: A high permeability metal casting plaster is used for production of high accuracy simulated castings for prototypes and any other plastermold castings. Methods are provided that create the high permeability metal casting plaster and mold. Also, a high permeability metal casting plaster is disclosed that uses control ground and screened .alpha.-hemihydrate gypsum such that an average of 100% of the particles have a diameter of no more than 590 .mu.m and an average of 97.3% have a diameter of less that 44 .mu.m, control ground and screened beta-hemihydrate gypsum such that an average of 99% of the particles have a diameter of no more than 270 .mu.m and at least an average of 70% have a diameter of less than 44 .mu.m, sucrose for protection against thermal shock, and a foaming agent. The ratio of .alpha.-hemihydrate gypsum to .beta.-hemihydrate gypsum is approximately 5:2.

Abstract: The present invention discloses a programmed learning device having a cover, a backing, and a leaf. An information sheet is releasably attached to the backing.

Abstract: The present invention discloses a shield that attaches to the upper guard of a hand held power saw. The shield prevents debris created by operation of the saw from hitting the user. The rotation of the saw blade creates moving air. The shield directs the moving air away from the saw and the user. The shield in translucent and can be made from polycarbonate.

Abstract: The present application describes a seat belt for use by a sleeper. In one embodiment, the first end of a belt is releasably attached to the second end of a belt. This belt is then attached to the existing seat belt system of a vehicle or to a seat belt bracket that is attached to the vehicle. In a second embodiment, a retractable belt encircles the seat.

Abstract: A low energy radiation dosimetry system includes an ionization chamber with a beryllium window that is optimized for flat response in the range of 6.5 keV to 40 keV. A conductive carbon coating including lithium and fluorine provides secondary electron emissions to flatten response of the beryllium window in the desired radiation energy range without the use of external mathmetical correction factors.

Abstract: A system for attachment of decorative trim members to trucks or recreational vehicles which is adapted for use with various makes of wheels. Specifically configured, trim member is placed over wheel having two opposite locator pins. Trim member is attached to locator pins using retaining clips. Trim member has further holes for receiving the lugs of the wheel. Decorative lug covers can be placed over lugs or integrally formed with trim member to cover lugs.

Abstract: Decorative interior molding is molded from a slurry of gypsum, water, perlite, and a foaming agent. The slurry is surrounded by paper, cured, and dried.

Abstract: A modular barrier and restraint for children or infants. The device has several interchangeable pieces, including substantially elongated barriers, rectangular end pieces, pyramidal end pieces, and castle end pieces. This interchangeability allows a one-dimensional, two-dimensional, three-dimensional, or four-dimensional barrier. Each piece is fitted with either a slot or counter slot to be fitted together to easily form the barriers. Holes may be placed through the pieces to form a handle. Other holes may be placed into or through the pieces to either provide a place through which a child or infant can see or into which a mirror can be placed.

Abstract: An interface between an archer's hand and an archery bow is provided whereby low friction, slidable movement of the hand at the hand-bow contact point is made independent of the bow. Lubricated latex rubber is disposed between the hand and the bow by means of an archer's glove, or a permanent or removable grip.

Abstract: An ironing board tray bracket for use in all modern ironing boards having a track that directs the extension and retraction of the ironing board legs. The bracket fits within the track and is adjustable to conform the width of the track. An arm attaches to the bracket on one end and a tray on the other end. The tray can be used for temporary storage of the iron or other ironing accessories. An iron clip is provided on the tray to hold the iron in place.

Abstract: A batting practice device has a first tether means attached to the top of a vertical pole at one end and supporting a ball and at the other end. A second tether means is attached to the pole and is attached to the first tether means above the ball.

Abstract: The present invention discloses a method for encapsulating and containment of asbestos covered workpieces such as power equipment material. A resin and catalyst mix is applied to the asbestos covered surface. Glass is applied with the resin or after the resin. The surface is then compacted by brushing or rolling, to provide consistent application and to remove air bubbles. In certain instances, this material is applied to a chopped roving which is then applied to the surface prior to compaction. In the preferred embodiment, a chopper gun is used to apply the resin, catalyst, and glass mixture.

Abstract: A limb protective covering having a tubular sleeve of waterproof material for receiving a limb and elongated closure member for tightening the sleeve around the limb. A portion of the sleeve above the closure member is folded over the closure member to form a cuff. A belt attaches to the cuff and wraps around the cuff to completely seal the covered limb.

Abstract: A percussion power handle is disclosed that allows a user to grasp plural percussion implements in each hand. The device comprises plural grips interconnected by a frame. Each grip releasably receives a percussion implement. A frame biases grips away from each other.
