Abstract: A proton cyclotron is provided for dedicated use in head, neck and eye cancers, tumors or other medical conditions including pediatric and other cancers or medical conditions. The method of using a proton cyclotron for treating a tumor, cancer or medical condition of a patient includes positioning the patient on a support platform, such as on a patient table or in a robotic chair, and irradiating the tumor, cancer or other medical condition using a proton particle beam from the cyclotron for a predetermined time sufficient to treat the tumor, cancer or medical condition, wherein the proton particle beam produced by the cyclotron has an energy in a range of 70 MeV to 150 MeV and has a beam current in an amount suitable for radiation therapy, as can include a variable range of beam current for the radiation therapy.

Abstract: A bicycle saddle has a seat post, an adjustment base, a seat, a sliding base, and two adjusting bolts. The seat post has a supporting base having a concave top surface and a passage. The adjustment base is attached to the concave top surface of the supporting base and has a convex bottom surface and an elongated through hole. The convex bottom surface matches and abuts the concave top surface of the supporting base. The seat is attached to the flat top surface of the adjustment base and has a sliding channel. The sliding base is mounted slidably in the sliding channel and has a slot and two holding rods respectively provided with a threaded hole. The adjusting bolts are mounted through the passage, the elongated through hole, and the slot, and are screwed respectively with the threaded holes in the holding rods.

Abstract: A robotic patient positioning assembly including a patient treatment couch, and a robotic arm coupled to the patient treatment couch. The robotic arm is configured to move the patient treatment couch along five rotational degrees of freedom and one substantially vertical, linear degree of freedom.

Abstract: A method and apparatus for feeding bristle bundle material into a magazine. The magazine is used in the production of brushes in which not all the bristle bundles extend in the same direction from the face of the brush. The feed apparatus for guiding the bristle bundle material from a supply to the magazine includes a number of transition plates having channels machined at an oblique angle to the surface of the plate. The plates each guide the bristle bundle material through a small angle; the assembled plates can guide the material through a large total angle so that the angle at which the bristle bundles enter the magazine is the same as the angle the bristles will have with respect to the brush.
