A sculptured drum for a retread process that has an inner radial section with a central axis that extends in an axial direction. The sculptured drum has a plurality of support members that extend outward from a drum outer surface in a radial direction and that are located outward from the inner radial section in the radial direction. A tread that has a plurality of grooves is supported by the sculptured drum during a brushing process and pass across the sculptured drum such that some but not all of the grooves have one of the support members disposed therein. The support members when disposed within the grooves do not completely fill the grooves, and when disposed within the grooves engage a lower surface of the tread.

A tire grinding machine includes a frame having a plurality of vertically extending posts. A chuck assembly is associated with the frame and adapted to receive and rotate a tire. A grinding assembly is associated with the frame and is movable with respect to the frame. The grinding assembly has at least one grinding element adapted to contact and remove material from the tire when rotated by the chuck assembly. A counterbalance assembly which has a cable with one end connected to a counterbalance weight and an opposite end connected to the grinding assembly is included. A block assembly may be coupled to the grinding assembly to allow pivotable movement thereof. A calibration adapter may be used to ensure proper positioning of the grinding elements, wherein a level adjuster may be used for this purpose.

A method of machining a tip profile of a blade for a turbomachine includes coupling the blade to a component of the turbomachine; supporting the component on a machining apparatus, the machining apparatus being configured to remove material from the blade according to a cutting path defined within a coordinate system of the machining apparatus, wherein the component is supported such that a datum axial end face of the component is aligned with a datum of the coordinate system of the machining apparatus; and machining the blade according to the cutting path. A system for machining a tip profile of a blade for a turbomachine accomplishes the method.

A tire pre-conditioning system includes a first mandrel, a second mandrel spaced apart from the first mandrel, and a controller in communication with the first mandrel and the second mandrel. The first mandrel is fixedly attached to a first shaft and including a first tapered sidewall. The second mandrel is fixedly attached to a second shaft and including a second tapered sidewall. The controller is operable to axially move the first mandrel and the second mandrel toward one another until the first and second tapered sidewalls are opposing respective beads of a tire, and supply pressurized fluid into an internal cavity of the tire to inflate the tire. The inflating causing the beads to move relative to mandrels while contacting the opposing respective tapered sidewalls to burnish the beads of the tire.

A cylindrical protective device is disclosed for the polished rod and packing of an oil well pumping system. The protective device is constructed with abrasive sandstone material, wraps around the polished rod, and is positioned on top of, or anchored to, the packing. The device has two symmetrical parts, each part having semicircular structure, the parts when joined together form a circular cavity to accommodate the polished rod therethrough. As the polished rod undergoes cyclic motion driven by a horsehead, the device smooths rough edges and oil chips, extending the polished rod's lifespan. By reducing friction and minimizing wear on the packing, the device prevents oil and natural gas leaks during the pumping process. Using the protective device, pump systems can operate more efficiently, ensuring a smoother and safer oil extraction process.

In one embodiment, the present invention provides a buffer brush. When rotating, the buffer brush acts as a centrifugal pump. The buffer brush contains a core having a first side and a second side and the brush extends racially from the surface of the core. The first and second sides have at least one opening configured to allow air to flow laterally through the core. Vents on the surface of the cure are configured to allow air flowing laterally through the core to also flow radially through the vents into the brush.

The invention relates to a tool for cleaning rollers (2a, 2b) of machines for closing container or cans, which comprises a head (1) which is couplable to a motor and on which are mounted: rotary drive discs (14) of the rollers (2a, 2b) to be cleaned and which comprise at least one element for making contact with the rollers, to transmit traction to same; at least one actuator disc (15, 16) that has a different rotation direction and/or rotation speed to the drive discs (14), and which is provided with at least one element for cleaning the rollers (2a, 2b); and a transmission (50) disposed between the motor and the discs (14, 15, 16).

A grinding tool for grinding an engine includes a main body with a central coupling region for connecting to a rotary drive of a grinding machine, the main body having a substantially rotationally symmetrical configuration with respect to an axis of rotation. The grinding tool also includes a grinding layer on the main body that extends over an outer circular ring zone of the main body, at least one feed for a cooling fluid, and a substantially circular cover plate arranged substantially normal to the axis of rotation and forming an axial gap on the main body. The axial gap is in fluid communication with the feed and the grinding layer so that a cooling fluid fed by the feed can be passed via the axial gap to the grinding layer.
