Abstract: The invention is intended to confirm whether the SOBP (spread-out Bragg peak) width is a desired value in real time during beam irradiation, and to improve safety in treatment. Ion beam delivery equipment comprises a beam generator including a synchrotron, an RMW (range modulation wheel) device for forming an SOBP width of an ion beam extracted from the beam generator, a beam delivery nozzle including a reference dose monitor and a main dose monitor which are installed respectively upstream and downstream of the RMW device in the direction of travel of the ion beam, and an SOBP width computing unit for computing the SOBP width of the ion beam, which is formed by the RMW device, based on values detected by both the reference dose monitor and the main dose monitor.

Abstract: The present invention provides a rapid indexing spindle drive and control apparatus for installation as a retrofit on a cam controlled automatic screw machine to provide the capabilities of variable spindle speed and direction as well as rapid indexing of the spindle in relation to the tool head of the screw machine for stationary tool operations. The apparatus includes a variable speed, low mass servo-motor mounted on the headstock of the machine and connected to the spindle by a 1:1 drive ratio timing belt and pulley system. A cam shaft revolution sensor is mounted adjacent to the screw machine cam shaft and is driven by the cam shaft through a second 1:1 drive ratio timing belt and pulley system. Electronically connected to the servo-motor and the cam shaft revolution sensor is a computer control system which includes a computer and an operator interface unit whereby cam shaft positions and spindle drive commands corresponding to specific cam shaft positions are entered by the machine operator.

Abstract: A spindle brake apparatus for add on attachment to automatic Swiss screw machines, comprising an idler pulley release assembly, a spindle brake assembly and a cam actuated control assembly employing the existing cam shaft timing and control means of such machines to stop spindle rotation so that cross milling operations may be performed. The apparatus is operated by compressed air in response to cam actuated valves to first release an idler pulley then apply the brake to stop spindle rotation. After a stationary operation is performed, compressed air is released thereby releasing the brake followed by reengagement of the idler pulley to reestablish spindle rotation.

Abstract: In a vehicle a safety frame and a cab, the cab entirely enclosing a personnel compartment is supported within the safety frame by resilient support members while the frame is rigidly mounted on the vehicle. Each of the support members includes at least one layer of elastomeric material secured between each of the leg members of the cab panel adjacent thereto for resiliently supporting the cab on the leg members such that in one embodiment the elastomeric material of each support member is loaded only in shear by the cab and in both compression and shear in a second embodiment, and the support members are in a plane containing the center of gravity of the operator and cab.
