  • Patent number: 9688485
    Abstract: The method of conveying samples using a continuous flow of pressurized air for conveying elongated items holding samples along a path in a tube system from at least one dispatch station, at which the elongated items are dispatched into the path, to at least one receiver station in the direction of the flow of pressurized air along the path. Individual items are sent in succession by means of pressurized air supplied to the tube system via the dispatch station and via a by-pass duct that extends around the at least one dispatch station from an upstream to a downstream side thereof. A constant flow of pressurized air is conducted via the by-pass around the at least one dispatch station into said path by which items already underway along the path in the tube system remain moving during dispatching of an item into the path.

  • Patent number: 8579202
    Abstract: Disclosed are a smart card-based browsing system, a smart card-based browsing method, and smart card for the same. A browser is installed in the smart card to form a direct connection path with an SCWS installed in the smart card. The number of sockets for HTTP request/response required to be as many as the number of contents for services between the smart card and the user terminal is reduced, so that the services can be smoothly provided through a rapid and effective interface. A web service can be provided to various multimedia appliances compatible with the smart card regardless of the existence of the browser on the user terminal and the type and version of the browser.

  • Patent number: 6930606
    Abstract: A security device, such as a security thread, uses multiple security detection features provided by combining metal and metal/magnetic security features on a carrier substrate. The security detection features basically comprise an optionally repeating pattern of discrete metal/magnetic indicia and discrete metal or metal-dot formed indicia. The security detection features may also include at least one metal strip extending along the length of the carrier substrate and/or a plurality of metal dots located on metal-free portions of at least one surface of the substrate.

  • Patent number: 6255948
    Abstract: A security device having multiple security features is used with an item, such as a secure document, ticket, label or tag, to authenticate the item and/or encode data pertaining to the item. One example of the security device includes a carrier substrate, a metallic layer disposed on the carrier substrate, and a magnetic layer disposed on the metallic layer in substantial registration with at least a portion of the metallic layer, thereby providing both metallic security features and magnetic security features. The metallic layer and the magnetic layer also form graphic or visually identifiable indicia on the carrier substrate to provide a visual security feature. According to one method, the metallic layer is applied to the carrier substrate, the magnetic layer is applied to the metallic layer, and the layers are etched to form the graphic indicia. The magnetic layer can, in one embodiment, include a magnetic chemical resist that is printed on the metallic layer in the form of the graphic indicia.

  • Patent number: 4221329
    Abstract: A perforation detector including a housing having a first portion and an oppositely disposed second portion for receiving the perforated area of a traveling web therebetween. One portion supports an optical signal emitter and the other portion supports a receiver for detecting the optical signal. The first portion is connected to a source of pressurized fluid such as filtered air. Such portion has a passage for directing the fluid flow, in the form of a fluid curtain, about the optical element in that portion and toward the optical element in the second portion. The fluid flow thus prevents accumulation of signal interferring particulate matter on and between the optical elements.

  • Patent number: 4208576
    Abstract: A pneumatic apparatus used for reading punch cards containing processing condition data for articles being processed in an automatic system. The apparatus has a pneumatic reading head for reading the punch cards, and the head has a plurality of air conduits therein. Each conduit has an inlet and an outlet. An air supply is connected to the air conduits for supplying air thereto, and a back pressure detector is provided in each conduit for detecting back pressure therein. The apparatus also includes a movable carrier jig for holding and carrying the article being processed in said system and the jig has a card fitting portion thereon for holding the punch card. The carrier jig is movable toward and away from the conduits so that the card on the card fitting portion can be positioned adjacent the outlets of the conduits.
