Abstract: This invention relates to an improved radially expansible tire assembly drum (10) and a method forming tires (2) from an assemblage of tire components utilizing the assembly drum (10).

Abstract: A pneumatic radial ply tire 20 has a tread 24, a carcass 21, and a belt reinforcing structure 40. The carcass 21 has a steel cord reinforced radial ply extending from one annular bead to a second annular bead. The belt reinforcing structure 40 has at least two belt layers 40A, 40B having steel cords 14 with large filaments 17A, 17B, 17C, 17D in the range of 0.3 mm to 0.6 mm in diameter twisted into a 7×7 cord construction.

Abstract: A vulcanization mold is described for the manufacture of technical rubber products comprising a plurality of vent bores in which a blocking member is mounted which consists of a central body and a sealing part coupled to it which together form at least one angled flow path for air to be dissipated, with the central body being fixed in the vent bores, on the one hand, by clamping ribs provided at the central body and, on the other hand, by blocking elements which are formed at spring limbs of the sealing part.

Abstract: A method of an apparatus for cutting segments (10) to desired lengths from a strip (1) of elastomeric tire components having at least one cord reinforced component involves the step of impacting one cord (22) as the cut is being made and lifting the cord (22) to avoid cutting cords (22) while directing the cutting path along the lifted cord(22). The article resulting from the method has a plurality of cords (22) adjacent a flat cut splicing surface (8) suitable for lap splicing.

Abstract: A radiation shield is provided for use on patients undergoing radiotherapy treatment. The shield is made of a suitable radiation absorbing material for preventing the transmission of high energy radiation to the patient's non-treatment areas. The device may further comprise an exterior surface layer for absorbing low energy photons. The shield is sized and shaped to conform to a patient's anatomy and to provide the necessary amount of absorbing material closest to the beam edge while not interfering with the beam. The shield may further comprise an optional cavity located on the interior surface of the shield which may be lined with a soft compressible material for conforming to a patient's unique anatomy. The shield may be further provided with dosimeters mounted on the exterior surface of the leading edge as well as on the interior surface of the shield.

Abstract: A rotary inlet flow controller, with one or more open ducts extending therethrough, aerodynamically controls the amount and velocity of the flow of air to combustion chambers of pulse detonation engines, or other engines, without imposing large cyclic airflow transients in the diffuser of the air intake. The ducted rotary inlet flow controller supplies airflow and sealing in synchronization with the cycles of the engine: airflow and fueling supply, sealing, combustion, and re-opening for additional airflow. This controller will supply near-uniform, continuous airflow to the engine. The preferred controller has one or more propeller-like blades that are designed to cyclically and sequentially duct incoming flow to the inlet ports of the combustion chambers, while also providing the capability of sealing the ports during combustion.
