Patent number: 6315474Abstract: A paper cutter assembly for a printer/plotter is mounted on the printhead carriage for movement therewith to avoid separate mounting and guide structure. A cutter wheel is mounted in a housing for cam induced movement between a raised inactive position and a lower active position by engagement of a cam element carrier mounted for movement in the cutter housing with structure on the printer chassis. The printer platen has a stationary cutter bar which extends in a channel in the platen transversely of the path of paper movement and has a cutter wheel receiving well at one end of the channel into which the cutter wheel drops without contacting the platen or cutter bar at commencement of a cutting operation. Camming surfaces on the platen engage the side of a cutter drive wheel to move the cutter wheel into engagement with the cutter bar and then to raise the cutter wheel to the proper amount of operational overlap of the cutting edges as the cutter assembly moves across the paper path.Type: GrantFiled: October 30, 1998Date of Patent: November 13, 2001Assignee: Hewlett-Packard CompanyInventors: Robert Giles, David Hermida, Tony Lang

Patent number: 6274230Abstract: A process for producing sharp surface visible patterns on composite articles formed of resin coated reinforcing strands employs a liquid uncured resin having a coloring component therein to produce an opaque resin of light color to mask the color of the reinforcing strands. An absorbent surface veil is applied to the surface of the article before curing the resin to produce an absorbent opaque surface layer of light color into which a pattern of contrasting color is then transferred by sublimating an ink or dye pattern from a pattern carrier into the opaque resin impregnated surface layer and veil. Articles ready for application of the surface pattern thereto by sublimation may be produced using pultrusion or hand lay-up methods. Distribution of the surface pattern partially or entirely through the thickness of the surface layer results in an article having a surface in which the pattern remains sharply visible despite surface wear.Type: GrantFiled: June 25, 1999Date of Patent: August 14, 2001Assignee: Jas.

Patent number: 6213488Abstract: A light weight high strength bicycle seat post comprised of a metal tube having a pre-stressed, tubular composite core therein, with the core having an exposed end extending from the tube, and method making same are disclosed in which the tube includes a composite core compressively engaged with the interior of the metal tube. The composite core is compressively restrained inside the metal tube by compressive stresses in the order of not less than about twenty thousand pounds per square inch. The composite core is formed of a plurality of layers of carbon fibers in a triaxial arrangement. The method of making the bicycle seat post consists of inserting an uncured composite core into a metal tube and expanding the core into engagement with the metal tube under heat and pressure to cure the composite and establish a light weight high strength bicycle seat post. Accordingly, the article is particularly useful as a bicycle seat post that possess strength, rigidity, and light weight.Type: GrantFiled: December 1, 1998Date of Patent: April 10, 2001Assignee: Jas.

Patent number: 6209397Abstract: The invention concerns a membrane for a pressure sensor. The membrane has, on a flat central face (26), an annular attachment face (12), which is disposed concentric to the central face (26), and a non-flat connecting face (54), which links the central face (26) with the edge face (12). The connecting face (54) is formed from at least one annular step (36, 44, 52), which consists of one flat annular face (32, 40, 48) and one truncated-cone-shaped step face (30, 38, 46), which connects radially inward to the annular face. The annular faces (32, 40, 48) and the central face (26) lie in planes parallel to each other, whereby the heights (h1, h2, h3) of the step faces (30, 38, 46) measured perpendicular to the plane of the central face are very small in relationship to the width of the respective step. This stepped design of the membrane results in a high linearity of the characteristic of the membrane pressure sensor and at the same time to a steep slope of the characteristic in its linear region.Type: GrantFiled: December 15, 1997Date of Patent: April 3, 2001Assignee: Wika Alexander Wiegand GmbH & Co.Inventors: Heinz Heller, Kurt Neubeck, Robert Schwagerl

Patent number: 6206512Abstract: A replaceable ink delivery tube system for a large format ink jet printer includes four flexible ink delivery tubes arranged in parallel and each permanently connected at one end to a printhead connector and at the other end to an off-axis ink reservoir receiving connector which, when mounted in the printer, is accessible from the front side of the printer to insert and remove four separate ink reservoirs from the ink reservoir connector. Lockouts are provided at both the printhead connector and ink reservoir connector ends of the replaceable delivery tube system to ensure that only ink reservoirs and printheads of the correct type can be attached to the replaceable system. The replaceable ink delivery tube system enables rapid modification of a printer to accept either pigment based or dye-based inks and the lockouts prevent pigment based ink reservoirs and printheads from being connected to a dye-based ink replaceable tube system or vice versa.Type: GrantFiled: January 29, 1999Date of Patent: March 27, 2001Assignee: Hewlett-Packard CompanyInventors: Xavier Gasso, Antonio Monclus

Patent number: 6190007Abstract: A printhead carriage for an ink jet printer having a plurality of printhead stalls therein and a printhead holddown cover having spring biased printhead holddown plungers on the underside of the cover and equal volume fluid passageways in the cover for conducting fluid from fluid inlets on said cover exposed to atmosphere to printheads in the stalls. An arcuately moveable air pump is engageable with one of a number of arcuately positioned inlets to the passageways in the carriage cover to enable a single pump to selectively apply positive pressure to prime each of the printheads in a desired sequence.Type: GrantFiled: February 17, 1999Date of Patent: February 20, 2001Assignee: Hewlett-Packard Company Intellectual Property AdministrationInventors: Christopher C.

Patent number: 6176640Abstract: A tubular structural part made of composite material such as carbon strand reinforced epoxy resin is provided with an elongated flat area along the outer surface of the tubular part to avoid cracking of the part when the part is telescopically engaged with and clamped in an outer tube part. The flat clamp side area of the inner tube part prevents contact between the facing edges of an elongate split in the outer tube part which are drawn together during clamping so that the edges of the outer tube part are prevented from coming into contact with and thus gouging the outer surface of the composite tube causing cracks and eventual structural failure of the inner tube.Type: GrantFiled: July 14, 1999Date of Patent: January 23, 2001Assignee: Jas. D. Easton, Inc.Inventor: Robert Gonczi
