Abstract: A revolving door assembly in which the individual door wings are releasably secured to a central support member, such that the door wings are retained in respective operative positions in which the wings extend substantially radially from the central hub in diametrically opposed pairs. The door wings are releasable from their operative positions in response to the exertion of a predetermined force thereon to allow one or more of the door wings to be rotated about their respective pivot axes to a folded position. The support member has a plurality of arm members projecting substantially radially therefrom. Each door wing is attached to a corresponding arm member by means of a ball and catch mechanism at a distal position relative to the support member. The ball is disengaged from the catch to allow the door wing to swing free of the arm member when a predetermined force is exerted thereon.

Abstract: A replacement cartridge for replacing spent ink ribbon on a continuous printer. The cartridge interfaces with the printer including a print head past which a document is advanced, a drive for feeding the ribbon tape, and a source of vacuum for effecting vacuum zones in which the feeding tape is buffered against acceleration shock. Included in the cartridge are a supply and takeup reel for the ribbon and between which the ribbon extends in a defined feed path through a pair of tape buffering vacuum chambers upstream and downstream of the print head. Magnets secure the cartridge to the printer at a guided interface in registry with the operative components of the printer. Pre-loading the ribbon in the cartridge entirely threaded throughout its feed path, enables replacement to be performed in a minimum of time requiring only the removal of the spent cartridge and immediately replacing it with the cartridge containing the reload of fresh ribbon.

Abstract: A printing system includes print ribbon wound on first and second rotatable reels and a rotatable capstan for moving the ribbon between the first and second reels, such that ribbon is supplied from the first reel and is collected after use on the second reel. A microprocessor controls both the reel and capstan movements and computes the quantity of ribbon wound on each reel based on a known diameter of the capstan and the relationship between the number of rotational steps moved by the capstan and the number of rotational steps moved by the corresponding reel during a given time period. The microprocessor includes a random access memory in which a plurality of ramp tables are stored for controlling the movements of the reels. Each ramp table includes a speed parameter representing a particular rotational speed and an acceleration parameter representing a number of rotational steps for ramping up to and down from the particular speed, for a discrete range of ribbon diameters.

Abstract: Disclosed is a graphics display system having a plurality of discrete light sources disposed along, and forming an integral part of, an illustration which is printed upon a shirt or other substrate. A battery-powered pre-programmed timing control circuit selectively illuminates the light sources disclosed as light-emitting diodes extending through openings in the shirt, to produce animation of the illustration and in particular motion of an item from one location on the illustration to a spaced location thereof.

Abstract: Air freshener apparatus comprising a cup-like base in which a quantity of fragrance emitting ingredient is disposed in at least a partially exposed relation. Secured air sealed about the support is a tubular bellows a soft, pliable composition forming an air chamber overlying the exposed relation of the fragrance ingredient. Breather holes formed through the support underlying the fragrance ingredient therein enables dispensing of a controlled quantity of fragrance scent by manually compressing the bellows. An adhesive pad on the undersurface of the support enables the apparatus to be attached to a recipient surface. Merchandise packaging of an air freshener unit includes a blister wrap of pliable composition having an aperture communicating from inward to outward thereof. This enables on-site consumer testing of the unit by depressing the wrap which in turn compresses the bellows to effect a scent emission outward through said aperture.

Abstract: Method and apparatus for enhancing the image capture of data, such as MICR characters and handwritten and printed information from the face of financial documents having background patterns and illustrations thereon. The documents are back lighted with sufficient illuminating intensity to wash out the less opaque patterns and illustrations so as to enhance the visibility and image capture of the pertinent data.

Abstract: A mechanism for encoding continuously moving documents. Documents are transported between a plurality of fixed dies and a plurality of electronically controlled hammers. An ink bearing ribbon is interposed between the documents and the fixed dies and is momentarily transported at the same velocity as the documents. As the documents traverse the plurality of fixed dies, the electronically controlled hammers are cycled, in a selected sequence and at selected positions, to provide the desired encoding. In those applications wherein the cycle time of the electronically controlled hammers is too slow to allow identical encoding in adjacent position, a second plurality of fixed dies and electronically controlled hammers may be located adjacent to the first plurality or interspersed among the first plurality of fixed dies.
