Patent number: 6230347Abstract: The use of particulate stuffings such as down or fiberfill in the construction of orthopaedic pillows has previously been limited due to formidable intrinsic difficulties: On a curved wedge of support, with natural turning movement of the sleeper, fiberfill will tend to “avalanche” downhill, settle and pack down to obliterate any initial toricity or inflected curvature. Hence the sleeper is awakened to refluff or to punch the missing inflection back into place. Though simple internal partitioning can initially delay the scenario, in due course nuisance fiber sequestering and impeded normal hand refluffing are the results. The present invention focuses on structurally overcoming these impediments to the orthopaedic use of particulate fillings. It notably provides a pillow that manifests to the sleeper as downy soft, and comfortingly restful.Type: GrantFiled: October 15, 1998Date of Patent: May 15, 2001Inventor: Christina Alexander

The opposing inner surfaces of the support are curved to form a keyhole shaped space between the support sections sized to permit the neck rest to comfortable fit around a person's neck without feeling yoked. The top surfaces and bottom surfaces of said support sections are preferably flat with rounded, the top surface of the pillow portion is higher than the top surfaces of the support sections and is curved to fit comfortable against the nape of the users neck. A flocking material is applied to the exterior surfaces of the neck rest.Type: GrantFiled: August 4, 1999Date of Patent: May 15, 2001Inventor: Pano Patrikakis

Patent number: 6230376Abstract: The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes “nicking” the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the “nicking” of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.Type: GrantFiled: May 12, 2000Date of Patent: May 15, 2001Assignee: Milliken & CompanyInventors: Louis Dischler, Jimmy B.

An alignment and retaining pin made of a very strong material extends from a bore in the manifold into a bore in the insert. The manifold is heated and the inserts and pins are cooled prior to insertion into place to provide very tight fits when they are at the same temperature which very accurately aligns the melt ducts through the inserts. The combination of the inserts fitting tightly in the openings and the strength of the pins is sufficient to withstand the rearward forces from the pressurized melt being injected through the curved melt ducts to retain the inserts in place.Type: GrantFiled: December 6, 1999Date of Patent: May 15, 2001Assignee: Mold-Masters LimitedInventors: Jobst Ulrich Gellert, Helen Zhuang

Patent number: 6230385Abstract: An elongated wedge shaped spline can be used for joining work pieces in a dovetail joint. It can be used in joining a work piece, such as molding in a dovetailed joint. A divider track having a base support and a pair of spaced apart flanges extending at a right angle from the front surface of the base support is first affixed to a surface. The wedge shaped spline is positioned between and in abutment with the upper portion of the spaced apart flanges. A fan shaped mortise on the back surface of a work piece is positioned over the wedge shaped spline between and abutting the upper portion of the spaced apart flanges. Pressure is applied on the front surface of the work surface of the work piece for seating the work piece on the divider track, thereby forcing the wedge shaped spline between the flanges and spreading the flanges. The spread apart flanges engage the side walls of the fan shaped mortise for joining the work piece in a dovetailed joint with the divider track.Type: GrantFiled: April 7, 1998Date of Patent: May 15, 2001Assignee: Premark RWP Holdings, Inc.Inventor: Thomas J.

Patent number: 6230386Abstract: An automatic cutting and press-fitting apparatus 10 includes a wire transporting unit 25 for transporting a wire W to at least a cutting and peeling unit D and a terminal press fitting unit E, and a transporting and clamping unit 62 for transporting the wire W to the terminal press fitting unit E and transporting the wire W after press fitting. The wire transporting unit 25 has a nozzle 43 for guiding the feeding of the wire W. In the apparatus 10, a wire guide plate 71 is disposed between the nozzle 43 and the transporting and clamping unit 62 and is capable of moving in the vertical direction by a pneumatic cylinder 72. With the vertical movement of the plate 71, when the unit 25 is returned from the unit E to the D, it is possible to prevent the wire W from being caught on the cutting and peeling unit D incorrectly. Further, when drawing the wire W to the unit 62, the erroneous pinching of the wire W can be prevented by the plate 71.Type: GrantFiled: October 13, 1999Date of Patent: May 15, 2001Assignee: Yazaki CorporationInventor: Hiroshi Hasegawa
