  • Publication number: 20170097289
    Abstract: Systems and methods that enable automated processing of specimens carried on microscope slides are described herein. Aspects of the technology are directed, for example, to automated slide processing apparatuses capable of dispensing liquids onto microscope slides. Additional aspects of the technology are directed to methods of replacing a reagent pipette in automated slide processing apparatuses. The apparatus can include, for example, a reagent pipette assembly including a reagent pipette moveable between at least one loading position for obtaining reagent from a reagent container at a filling station and at least one dispense position. The apparatus can also include a retainer for releasably securing the reagent pipette. In some embodiments, the reagent pipette assembly includes a locking mechanism for transitioning the retainer from an open configuration for receiving a pipette and a closed configuration for securing a pipette, in e.g., an aligned position within the retainer.

  • Publication number: 20160280005
    Abstract: A tension-based non-pneumatic structurally supported wheel with reduced lateral stiffness having a compliant tread band and a plurality of web spokes for bearing the load in tension extending transversely across and inward from a compliant tread band for attachment to a hub. The web spokes have an increasing draft angle and decreasing width as they extend from the compliant tread band to the hub reducing the lateral stiffness of the wheel thereby reducing steering force feedback to the steering mechanism.

  • Publication number: 20160107402
    Abstract: A mold for forming a tire for a non-pneumatic or hybrid tire. The mold possesses a telescoping mold core having an angled shut off surface that extends past the cavities and into a mold half and contacts or nearly contacts the mold half on the angled shut off surface which changes the placement and orientation of potential flash.

  • Patent number: 9290045
    Abstract: The present invention provides spoke geometry for a non-pneumatic tire that is less prone to fatigue when used. In particular, the spoke geometry is provided with an optimized thickness profile over the length of the spoke. This optimization results in a reduction in the peak strain energy density levels in the spoke, thereby reducing the likelihood of crack initiation and propagation which in turn enhances the durability of the spoke and tire.

  • Patent number: 9254716
    Abstract: An improved spoke edge geometry for a non-pneumatic or hybrid tire. The spoke edge geometry possesses a reduced cross-section that reduces the bending stresses locally and allows a unique mold construction that changes the placement and orientation of potential flash.

  • Patent number: 8900857
    Abstract: A mould and tissue cassette for automated embedding of tissue, and a method of operation are disclosed. The mould attaches to the cassette prior to embedding, and fits into a rack. The rack supports the mould holding the tissue cassette when the mould and cassette are in a first position. When the mould and cassette are moved to a second position, a projection on the rack separates the mould from the cassette, to facilitate easy removal. Also disclosed is a mould for a tissue cassette having projections for holding the mould to a rack, so that the tissue cassette is not in contact with the mould.

  • Publication number: 20140345763
    Abstract: A tire comprises at least a left tread portion, a right tread portion, wherein the left tread portion and the right tread portion are axially separated by a longitudinally oriented groove. A tread reinforcement comprises a plurality of tread reinforcing layers wherein the reinforcement elements are formed of parallel reinforcements arranged in opposing layers, and each of the opposing layers has a bias angle relative to the circumferential direction. The bias angles of the reinforcement elements in each of the tread reinforcing layers corresponds to a plurality of equilibrium membrane shapes determined from membrane equilibrium equations that are joined together to create a continuous, complex shape.

  • Publication number: 20130240097
    Abstract: The present invention provides improved spoke edge geometry for a non-pneumatic or hybrid tire that is less prone to fatigue when used. The present invention also provides a way to manufacture such geometry in a mold, In particular the spoke edge geometry is provided with a reduced cross-section that reduces the bending stresses locally and allows a unique mold construction that changes the placement and orientation of potential flash and reduces other potential molding flaws when a liquid such as polyurethane is introduced into the cavity of the mold to form a spoke. This change results in a reduction in the possibility of a stress riser being found near the edge of the spoke, enhancing the durability of the tire.
