摘要： An automatic lay-up machine is disclosed for composite material article having anisotropic resistance in tension. A layer of fiber material, either unidirectional or fabric weave, is dispensed between a supply roll and a take-up roll. This material is advanced over a cutting table having at least one and preferably a plurality of cutting molds, each mold cutting a profile of a portion of an article being fabricated and leaving a continuous scrap webbing for gathering at the take-up roll. The material is placed under tension across the cutting table, compressed, and cut at the molds to extract the individual layers having the desired sections utilized in fabricating the article. This process is repeated with the molds indexing in rotation with respect to the material so that successive layers filling the molds align their respective fibers in varying directions. Sufficient scrap material is left between the cutting table and the take up roll that tension can be drawn through the un-severed fiber sections as material is sequentially advanced across the cutting table. Where pre-impregnated composite tape or fabric are used, refrigeration of the supplied tape with following adhering to form a unitary article or article part occurs. Alternately, built up layers of composite layers without resin can be impregnated with resin. This article or article part is then cured as a unitary mass.

摘要： A centrifuge construction is disclosed in which a centrally located stator directly drives a peripheral ring shaped centrifuge rotor. In the preferred embodiment, a centrifuge drive is disclosed which includes a stationary, central and usually cylindrical stator having stationary electrical windings for generating a rotating and driving magnetic field. The ring shaped centrifuge rotor is supported by at least one bearing relative to the stator and includes a large central aperture defined by the inside of the ring which enables the rotor to fit over and rotate about the stator. At portions of the rotor adjoining the stator, the rotor is constructed from materials which are entrained by the rotating magnetic field. The centrifuge rotor containing samples undergoing centrifugation is directly driven from the stator by entrainment of the rotor with the rotating and driving magnetic field generated from the electrical windings of the stator. In the usual case, this large central aperture in the rotor requires the use of composite materials in the rotor to resist radial centrifugal forces generated during centrifugation with hoop stress resistance from wound composite material fibers.

摘要： A method and apparatus for the compression molding of composite fiber fixed angle rotors is disclosed. A female mold member defines a closed cylinder cavity for molding the bottom surface of the rotor, this cavity usually defining a frustum shaped central cavity complimentary to and concentric with the spin axis of the ultimately formed rotor. A male mold member having a complimentary cylindrical profile contains a frustum shaped inner cavity with the apex of the frustum disposed to the inner portion of the cylinder and the base end of the frustum exposed to the cylindrical opening of the female mold. This frustum shaped inner cavity defines the exterior frustum shape of the ultimately produced rotor and defines between the exterior frustum profile and the frustum shaped inner cavity a rotor body wall having sufficient thickness to receive the sample tube apertures. At the apex end of the frustum shaped cavity in the male mold member, there is located a lock system for maintaining sample tube aperture cores. These sample tube aperture cores are locked within the frustum cavity in the precise alignment of the ultimately formed sample tubes of the rotor. Loading of the mold with resin pre-impregnated fiber typically occurs in the frustum shaped cavity of the male mold member and at the bottom of the female mold member. A compression molded rotor product is disclosed having discontinuous fibers optimally disposed to resist the forces of centrifugation.

摘要： A fixed angle rotor and method of manufacture of a fixed angle rotor has a frustum shaped rotor having rounded surfaces reinforced by filament tow windings against both vertical and horizontal forces generated during centrifugation. A so-called "high speed" rotor has a bottom composite disc, a top composite disc, and a frustum shaped hollow fiber reinforced molded insert between the respective discs having a stepped exterior surface. An "ultra speed" rotor has a bottom composite disc, a top composite disc, and composite discs therebetween defining a stepped exterior surface. In both cases, these exterior steps have surfaces which capture the windings to the exterior of the rotor. A first class of individual fiber windings about the rotor is applied having a vertical reinforcement component parallel to the spin axis and normal to the laminate layers. These windings include either vertically disposed loops in grooves on the stepped exterior of the rotor which tie the top and bottom discs together (with the remainder of the rotor securely sandwiched therebetween) or vertically disposed windings in exterior grooves which extend over both top and bottom discs of the rotor. A second class of windings includes circumferential windings on the step surfaces of the rotor. Such windings are applied to fill in the stepped surfaces as well as to resist centrifugal forces of centrifugation.

摘要： In a centrifuge having a central stator with a peripheral rotor, an improved suspension for the rotor is disclosed. The central stator is provided with a bore coaxial to the axis of rotation of the rotor. The rotor of the centrifuge motor has a quill shaft support member extending into and rotating within the coaxial bore of the stator. A quill shaft attaches at the bottom of the quill shaft support member and extends upward above the rotor of the centrifuge motor to support a fastening hub for the centrifuge rotor. The rotor of the centrifuge is detached from the rotor of the centrifuge motor so as to define a spatial interval between the supported spinning rotor and the rotor of the motor driving the centrifuge. The centrifuge rotor attaches at the hub and depends downward from the hub with the spatial interval being defined between the rotor of the motor and the rotor of the centrifuge. It is noted that the center of gravity of the attached centrifuge rotor is well below the hub so that support of the rotor is inherently stable. In the preferred embodiment, heat transfer shielding material is placed over the rotor of the motor. Operation is quite and smooth with the inevitable rotor imbalances being absorbed by quill shaft flexure.

摘要： A fixed angle centrifuge rotor body is constructed from compression molded composite material. The rotor body has a frustum shaped peripheral contour about a central spin axis between a base end and an apex end. The body has net shaped angled sample tube apertures defined in the rotor body extending from openings in the apex end adjacent the spin axis of the rotor body to bottom portions of the sample tube apertures more remote from the spin axis of the rotor body. The rotor body is formed from resin cured about discontinuous composite fiber with the major axis of the discontinuous fiber disposed normal to the spin axis of the rotor body interior of the rotor body. The resin cured discontinuous composite fibers exceed 40 weight percent of the cured rotor product and have no visible layering between respective fibers. The resin cured discontinuous composite fibers have minor vertical excursion parallel to the spin axis of the rotor and relatively no kinking along their respective lengths. The resin cured discontinuous fibers are disposed parallel to the surfaces of and about molded sample tube apertures in the rotor body.

摘要： In a fixed angle centrifuge having sample tube apertures symmetrically distributed around the spin axis of a rotor body, two rotor body shapes are disclosed at the rotor body top adjacent the openings to the sample tube apertures. These shapes each permit both release of the sample tube aperture cores and maintain the intersection of the top of the sample tube aperture within a plane normal to the axis of the sample tube aperture. A first shape includes placing discrete facets at the top of the rotor body adjacent the sample tube aperture openings. The second, and preferred embodiment, includes generating a spherical surface utilizing a spherical radius which is taken from the intersection of the spin axis of the rotor and the axes from each of the sample tube apertures. In both cases, precise termination of material molding the rotor body occurs at the top of the cylindrical portion of the sample tube aperture. Sample tube aperture core withdrawal easily occurs. Further, the ultimately formed sample tube aperture easily supports the sample and sample tube during centrifugation.

摘要： In the compression molding of a fixed angle centrifuge rotor utilizing discontinuous fibers, sample tube apertures cores present in the net-shape mold are covered with pre-cured sample tube aperture inserts. The sample tube aperture inserts have a constant and unchanging inside diameter and are formed from composite fiber. This composite fiber extends from the closed bottom of the inserts, upwardly along the sides of the inserts to the open top of the inserts to provide tensile strength longitudinally of the sample tube aperture inserts. The sample tube aperture inserts have a regular and smooth inside for first accommodating the sample tube aperture cores when the rotor is compression molded and later the sample tubes themselves when the rotor is fully fabricated. These inserts have an irregular outside for forming an interference fit with the subsequently formed compression molded rotor body. Finally, the sample tube aperture inserts have a tapered thickness with the top and open portion of the inserts having a thick wall construction and the bottom and closed portion of the inserts having a thinner wall construction. In use, and when the compression mold is loaded, the sample tube aperture inserts are placed over the sample tube aperture cores. When the mold is fully loaded, and compression molding occurs, the inserts integrally form to the rotor body and the sample tube aperture cores are removed.

摘要： A swinging bucket rotor constructed of composite material has a central rotor body including strap retaining surfaces. Wound endless composite fiber straps are provided having central portions which are attached to the respective top and bottom of the central rotor body and loop portions remote from the central rotor body for mounting the swinging buckets. These wound endless straps attach centrally to the central rotor body at the strap retaining surfaces and define bucket retaining loops symmetrically spaced from the spin axis of the rotor at the central rotor body. In the preferred embodiment, each bucket retaining loop holds spaced apart bushings for receiving a trunion shaft. Paired trunions on either side of a central sample tube receiving ring are provided. The trunions fit to the composite loop portions of the endless composite material straps. Typically, four sample receiving buckets are placed within and held by the central sample tube receiving rings. Such loading of the buckets occur by the bucket being lowered into the sample tube receiving rings until they are pendulously supported through the rings by the trunions. There results a swinging bucket rotor having top loading sample tube apertures constructed at its sample retaining loops from composite material disposed in tension with the benefit of reduced construction cost and operational complication.
