Title: Marker lamp with led array and prismatic diffuser
Inventor: HUTCHISSON JAMES T
IPC: H05B44/00
Filed: 1993-06-08
Granted: 1996-11-26
Abstract: A lamp assembly (10) for use as a vehicle marker lamp or a vehicle clearance lamp is disclosed. A lamp assembly includes a multifaceted prismatic diffuser (12) to which a number of LEDs (14) are fitted. The diffuser has an outwardly directed por-tion (20), a center portion (22), and an inwardly directed portion (24). The outwardly directed portion and inwardly directed portion are both formed with angularly offset facets (26-38). The LEDs are fitted into openings (40) that are formed in the facets (32, 34) of the inwardly directed portion of the diffuser. When the LEDs are ener-gized, the light emitted thereby is initially diffused throughout all of the diffuser. It is then emitted from the facets forming the outer portion of the diffuser such that it can be seen over a wide viewing angle.

Abstract: An improved runner (14) for use with a Sailrail hydrostatic bearing levitation system is disclosed. The runner (14) uses a substantially solid core (34) having a degree of flexibility in a vertical plane, a thin pad (40) of flexible, compliant material ex-tending transversely around the core (34), and an outer flexible, compliant sheath (42) enclosing the pad and the core. Flexibility is enhanced by a longitudinally extending slot cut (58) into the core from the upper surface thereof. The sidewalk of the core are flat and straight and meet the lower convex surface (38) of the core (34) at a sharp longitudinal edge (54). Also the ends of the runner (14) can angle upwardly to enhance the ability of the runner to traverse joints, gaps, or imperfections in the Sailrail rail. The runner can be secured to a deck member (16) and provides specific advantages over prior art runners which had a larger pro-file, were more expensive and were not as efficient as the low profile runner of this invention.

Abstract: Raw sewage ("black water" from toilets), wastewater from showers, sinks, kitchen facilities ("grey water") and oily water from the bilge of a host vessel ("oily water"), in combination, unexpectedly provide the essential nutrients for a live mass of mixed microorganisms which are peculiarly well-adapted to ingest the nutrients. To facilitate availability of oxygen to the microorganisms as to provide growth of the microorganisms, and also, to allow them destroy to themselves, excess oxygen is discharged, in a combination of microbubbles and macrobubbles, into a membrane bioreactor ("MBR"). The mixture of bubbles is preferably generated with coarse (>2 mm) and fine (< 20µm) bubble diffusers. An auxiliary stream, whether alone, or a recirculating stream into which air is drawn, may provide the coarse bubbles. The air is entrained, in a jet aerator or eductor, in a recirculating loop of activated sludge taken from the MBR. Another portion of the contents of the MBR is pumped to a semipermeable membrane which provides water (permeate) of excellent quality. The remaining concentrate is led to a gas micronizing means which produces a tail-jet of microaerated concentrate. The tail-jet is returned to the MBR to provide kinetic energy for maintaining a high velocity of liquid flow in the MBR. A portion of the concentrate is disposed of. Preferably the liquid waste to be treated on-board does not substantially exceed about 21 meters3/day.

Abstract: The invention relates to over and under delivery sheet accumulators. Prior sheet accumulators required considerable time to adjust the accumulator for pass-through, under or over sheet delivery. The present invention solves this problem by providing a retractable ramp mechanism which allows for quick and easy adaptability to optionally over or under accumulate and to optionally pass-through sheets without accumulation into stacks. The retractable-ramp accumulator includes driven endless elastic belts (10, 12) to feed sheets therebetween along a sheet-feeding path (24), a sheet stacker (26) having a stacking location and including a selectively releasable stop gate (16), and at least one selectively retractable ramp (14) for selectively deflecting sheets out of the sheet feeding path (24) for selectively feeding under or over previous sheets that are stopped in the stacking location by the stop gate (16). In one embodiment, an upper and lower set of ramps (37, 76) are arranged such that while one set of ramps is retracted, the other set of ramps is interposed in the sheet feeding path (24), so that sheets can selectively be "over" ar "under" accumulated.

Title: A writing implement using liquid ink, in particular a solvent-based ink
Inventor: CHAVATTE PHILIPPE
IPC: B43K8/04
Filed: 1995-05-08
Granted: 2006-02-21
Abstract: The writing implement using liquid ink is constituted by: a) a body whose rear portion constitutes a reservoir for the ink; b) a transfer rod whose rear end opens out into the reservoir and whose front end projects out from said body and forms a writing tip; and c) a buffer reservoir in contact with the transfer rod.      The surface tension of the ink lies in the range 21 mN/m to 25 mN/m, and is intended for use on non-absorbent media made of metal or of plastic. The surface tension of the material constituting the buffer reservoir is less than that of the ink by a determined difference which is preferably equal to or less than 4 mN/m, thereby enabling the buffer reservoir to absorb and give back any excess ink coming from the transfer rod by capillarity in the event of variation in the pressure inside the reservoir.      The buffer reservoir may be made of a material whose surface tension has been lowered by depositing an agent whose surface tension is less than that of the ink while lying within the determined difference, e.g. fluorine, polysiloxane, or a fluorine-containing resin.

Title: Apparatus and method for anchoring sutures
Inventor: BARTLETT EDWIN C
IPC: A61B17/00
Filed: 1994-09-19
Granted: 2005-04-26
Abstract: A suture anchor having a conical surface and a bore in which an end of an insertion tool is inserted. The insertion end of the insertion tool is made of material having elastic properties. The bore and base of the suture anchor are angled with respect to the central axis of the suture anchor and preferably are parallel to each other. During insertion, the suture anchor is reoriented to fit into the hole, thereby bending the elastic and of the insertion tool. When the suture anchor is within cancellous bone tissue, the elastic properties of the insertion tool deploys the suture anchor to an orientation in which the suture anchor cannot fit through the bone hole, thereby firmly anchoring the suture anchor in the human bone.

Abstract: An adjustable elastomer torsion device includes a base member aligned in partially nested relation with a resilient elastomer (e.g. rubber or urethane resin) torsion member; parts of the base member and the torsion member overlap each other and an extension portion of the torsion member projects beyond the base member.  The base member and the torsion member are interlocked, where they overlap each other, to prevent relative twisting between them, but the interlock does not interfere with twisting of the torsion member extension.  An adjustment mechanism provides for adjustment of the positions of the base and torsion members relative to each other to vary the length of the extension portion of the torsion member over a given displacement length and thereby adjust the elastomeric, resilient torsional restoration force (torsional resistance) of the device within a predetermined force range.  In some versions, the base member is a resilient elastomer, so that some twisting occurs in the base member; in others the base member does not twist preceptibly.
