Abstract: A method for encoding and decoding the digital information sequence uses a combination of two block codes to simultaneously correct and detect errors. The information sequence is encoded by a first stage of the encoder to produce an information code word including an information vector and a primary redundancy vector. The primary redundancy vector is encoded in a second stage of the encoder to obtain a redundancy code word. The information code word and redundancy code word are interleaved and transmitted to the receiver. At the receiver, the information code word and redundancy code word are decoded in a first stage of the decoder to obtain a first estimate of the information code word. The first estimate of the information code word is decoded in the second stage of the decoder to produce a second estimate of the information code word. The distance between the first and second estimates of the information code word is evaluated. If the distance is more than one, the received code word is erased.

Each of the tilting conveyor carts includes a trailer frame base, a carrying tray for holding the objects and a two-axis tiltable support apparatus for supporting the carrying tray above the trailer frame base and for allowing tilting of the carrying tray towards at least one side of the conveyor to unload objects into unloading stations on at least one side of the conveyor.

Abstract: A process for lubricating acrylic fibers before dyeing in which packages of acrylic yarn formed by winding acrylic yarn about a dye tube are treated immersed in an aqueous lubricating bath containing a polyethylene, a low melting paraffin wax emulsion; and a high melting paraffin wax emulsion, followed by raising the temperature of the bath, to sequentially coat the fibers of the yarn with the polyethylene, the low melting paraffin wax emulsion, and the high melting paraffin wax emulsion. The yarn packages are then separated from the lubricating bath, and immersed in a dye bath to dye the yarn. In commercial application, the lubrication and subsequent dyeing is conducted in the chamber of a dye machine.

The rubber modified polyolefin is a rubber modified polypropylene or polyethylene homopolymer and copolymer. The rubber is natural or synthetic. The preferred thermoplastic olefin film has characteristic melt peaks at temperatures ranging between about 61.degree. C. and 100.degree. C. and between about 105.degree. C. and 168.degree. C., with melt peaks forming preferably at about 86.degree. C. and 142.degree. C. Acceptable thermal lamination of the layers occurs at temperatures ranging between about 120.degree. C. and 140.degree. C.

Abstract: The present invention is directed towards an untethered microphone associated with a radio telephone base and adapted to provide wireless communication therebetween. The remote microphone may include a rechargeable battery and a solar power supply and associated panel configured to recharge the battery. The remote microphone and base unit are adapted to each transmit and receive data and control signals therebetween. The remote microphone is further adapted to transmit voice signals from the microphone to the base unit during operation. Typically, a first transceiver is located with the remote unit, and a second transceiver is located with the hands-free base unit. Working together, the transceivers carry the microphone's signals to the radio telephone's transmitter. Additionally, the transceivers carry call-in-progress information back and forth between the microphone and the hands-free base unit.

The booklet includes an outer piece including a top panel and a bottom panel joined by an outer fold, an inner piece disposed between the top and bottom panels having a pair of interior panels joined by an inner fold, attaching means coupling the outer and inner pieces to one another at the outer and inner folds, and a tear line formed in the bottom panel adjacent the outer fold. A layer of adhesive is interposed between the bottom panel and the upper surface of the release liner.

Abstract: A new and improved method of dispensing, tracking and managing pharmaceutical product samples by communicatively linking prescribers and pharmacies to a central computing station. The method entails utilizing product trial media that is exchanged for actual pharmaceutical product. The media is encoded with information that identifies a particular pharmaceutical trial product, such as by magnetic encoding similar to that used with credit cards. The media is distributed to participating medical doctors or prescribers who then activate the media via the central computing station. The prescriber then transfers the activated media to patients who then present the media to participating pharmacies. Before filling the pharmaceutical trial product identified by the media, the pharmacy validates the media via a link with the central computing station. Then, the pharmacy dispenses the prescribed pharmaceutical trial product.

Abstract: An improved sweat band. The sweat band includes an elastic band adapted to fit around a user's head and a length of sponge cloth intermittently attached along spaced apart locations to the elastic band. Only the ends and spaced apart segments of the strips are attached to the elastic band, therefore allowing the elastic band to stretch without being restricted by the inelastic sponge material. In the preferred embodiment, a tubular fabric wrap surrounds the elastic band and the length of sponge cloth to provide additional absorption and also to provide comfort to the user.

Abstract: A filter cleaning apparatus for removing dust and debris from a stationary filter having a dust an debris collecting surface. The apparatus includes a longitudinally extending duct having a lengthwise slot formed therein. A belt in the duct extends across the slot whereby the duct and the belt together define a plenum. The belt has an opening formed therein adjacent the slot and in fluid communication with the plenum. The belt is mounted for movement along the slot such that the opening may be repositioned along the length of the slot. A nozzle is mounted on the belt for movement therewith and extends outwardly from the belt. The nozzle has an inlet distal from the belt. The inlet has a width substantially transverse to the length of the slot which is greater than a corresponding width of the opening in the belt. The inlet is in fluid communication with the opening and thereby the plenum. The apparatus further includes drive means for moving the belt along the slot.

Abstract: Water is prevented from entering the wall interior of a building from in and around a wall component, such as a window, mounted in the building wall, by positioning a diverter directly beneath the wall component. The diverter includes an upper surface that slopes toward the wall exterior, a plurality of spaced, parallel ribs extending upwardly from the upper surface and beyond the exterior wall to form a plurality of downwardly sloping channels, a cover over the outer ends of the ribs to form drainage openings at the ends of the channels, and filters in the channels to prevent water from entering the wall interior through the channels.

Abstract: A case for transporting exhibits and other materials includes a container having a bottom, two opposing sides, two opposing ends, and an open top. A wheel assembly is mounted at a first end of the container adjacent the bottom. First and second handles are disposed at respective ends of the container adjacent the open top.
