| 20080230170 | Method for vacuum forming an elastomeric tire - A vacuum forming process for manufacturing a transport tire from an elastomeric material that include steps of: in a mold having a cavity or annular area, positioning a transport tire core of plies, belt and beads that has been laid-up on a mandrel. Fitting a cover in sealing engagement over the mold top and fitting a cylindrical canister, that is open at a top end, through the center of the cover and into the mold center and pouring an elastomeric material mixture into the canister that includes a needle valve in its lower end that exhausts into one end of the mold annular area. The cylindrical canister includes a port for connection to a deep vacuum source and the cover includes a port that is for connection to a low level vacuum source, where the deep vacuum is to remove air from the elastomeric material mixture, and, after filling, is open to atmosphere, and the needle valve is opened to the mold annular chamber allowing the mixture to be pulled by the low level vacuum through the mold annular cavity, impregnating the transport tire core maintained therein. | 09-25-2008 |
| 20110041984 | Method and apparatus for retreading a heavy duty tire with a polyurethane tread - A method and apparatus for retreading a heavy duty tire with a polyurethane tread where, after a tire carcass is inspected for utility and is cleaned, the worn tire tread is removed and the carcass is reinspected to insure its suitability for retreading. The tire carcass, with a tube fitted therein, is installed on its side in a mold cavity, between top and bottom rings, that each include spaced segments extending from opposing top and bottom ring surface, and the segments inter-digitate and form the equal spaced tread voids in a finished recapped tire, and the bottom ring inner edge top includes a continuous lug for sealing against the tire side wall, and the top ring is open to pass a flow of polyurethane materials from a lower edge of a cone shaped spreader that is positioned onto the tire carcass top side wall and receives the flow of polyurethane materials directed onto the cone surface, the materials sliding as a sheet therefrom into the mold, filling the mold cavity from bottom to top, forcing air from the mold ahead of the fill, forming the recapped tire tread. | 02-24-2011 |

| 20080228204 | Limited Access Suturing Devices, System, and Methods - Medical suturing devices, systems, and methods will be useful for endoscopic (with or without access ports) or other surgeries in which access is limited, including ear, nose, and throat procedures. Articulation motions may be transferred from a handle to needle grasping jaws using an axial movement of a shaft that has axial stiffness (such as being stiff in compression) and lateral flexibility or an axial movement of a cable. An extension body (within which the shaft or cable moves) between the handle and jaws can be pre-bent or custom bent by the user. Portions of the devices may be disposable, replaceable, and/or reusable. A spring adjacent the clamp may open the clamp or impose a gripping force. | 09-18-2008 |
| 20080243147 | Replaceable Tip Suturing Devices, System, and Methods for Use with Differing Needles - Medical suturing devices, systems, and methods will be useful for endoscopic or open surgeries, including ear, nose, and throat procedures. Articulation motions may be transferred from a handle to needle grasping jaws using an axial movement of a shaft. Portions of the devices may be disposable, replaceable, and/or reusable, with different needle-grasping jaws and/or different elongate extension bodies having different configurations optionally being selectably coupleably to an articulatable handle and housing so as to allow the user to configure the device for a particular procedure. | 10-02-2008 |
| 20100185218 | Surgical Suturing Latch - Suturing systems may comprise a cartridge and a drive unit which are detachable from each other. The cartridge often has a cartridge body, a plurality of jaws, and a cartridge interface. The drive unit has a drive unit body, a linkage, and a drive unit interface which will typically include a latch. A latch input is coupled to the latch so that a movement of the input moves the latch to the released position. The cartridge interface or the drive unit interface includes a channel while the other includes a shaft which is fittingly receivable in the channel. Opposed motions of the input and cartridge during cartridge removal avoid inadvertent detachment during use. | 07-22-2010 |
| 20100268257 | SUTURING DEVICE, SYSTEM, AND METHOD - Improved medical suturing devices, systems, and methods may hold a suture needle at a fixed location relative to a handle of the device, allowing the surgeon to grasp and manipulate the handle of the suturing device to insert the needle through tissues in a manner analogous to use of a standard needle gripper. Cycling the handle from a closed position to an open position and back to the closed position may alternate the device between gripping the needle with a first clamp (for example, along a proximal portion of the needle) to gripping the needle with a second clamp (for example, along a distal portion of the needle) and optionally back to gripping with the first clamp, with the needle often staying at a substantially fixed location relative to the suturing device body. Related single-clamp needle grasping devices can be bent plastically by a surgeon, and/or have bodies that are grasped by a hand while a portion of the hand actuates a handle. | 10-21-2010 |
