Patent number: 6578679Abstract: The invention relates to a brake system for railway equipment. More particularly, the invention relates to brake devices and systems for pneumatically and manually actuating such devices on railroad train cars such as freight cars. The brake system can be integrated into modern trains without interfering with existing air brake systems. The brake system can be remotely operated, locally pneumatically operated and/or locally manually operated. Monitoring equipment for determining the status of the brakes from remote and local positions may also be provided. The invention may be configured to fit within the envelope of prior art handbrake systems.Type: GrantFiled: April 4, 2001Date of Patent: June 17, 2003Assignee: UTD IncorporatedInventors: John L. Hill, Donald B. Harris, Joram Shenhar

Patent number: 6382583Abstract: A safety device may be used to provide separation in the event of a side impact collision. The device may be used in a utility pole guy wire system, interposed between the guy wire and the ground anchor. The device operates in bending. A lateral force of sufficient magnitude applied to the device by the errant vehicle causes a rod within the device to break in tension, even though the tensile strength of the rod may be greater than that of the guy wire. In operation, certain massive portions of the device are tied safely to the ground, while other portions are pulled over the moving vehicle by the tension of the guy wire. The invention may be designed to tolerate axial loads, but to fail reliably when a side force exceeds a desired threshold. When installed in series with a utility pole guy wire, the invention will withstand all normal tensile and incidental loads, and will release when subjected to a high side force as from an automobile impact.Type: GrantFiled: April 18, 2000Date of Patent: May 7, 2002Assignee: UTD IncorporatedInventors: John L. Hill, III, Joram Shenhar, Stephen G. Solga, Donald B. Harris, Eugene L. Foster

Patent number: 5641027Abstract: A drilling system employs spaced apart cutting members arranged in a helical pattern to form a helical thread within a rock bore. The thread is efficiently fragmented by a wedge-shaped trailing cutting member. Advantageously, a substantial portion of the rock is removed by the fracturing of the internal thread in the rock bore by the uppermost cutting member, taking advantage of the weakness of rock in tension. The rotational speed of the helical cutting system may be controlled as a function of the axial thrust applied to a pilot bit located in front of the helical cutting system.Type: GrantFiled: January 9, 1995Date of Patent: June 24, 1997Assignee: UTD IncorporatedInventor: Eugene L. Foster

Patent number: 5417082Abstract: An insulated container for maintaining a product at a specific constant temperature during shipping or storage using two constant temperature coolants of different temperatures on either side of a highly conductive product storage box to establish a temperature gradient. Two pieces of insulated material of different thicknesses are placed between the product storage box and the constant temperature coolants. The selected thicknesses of the insulated material determine the specific temperature of the product, which will be between the temperatures of the two constant temperature coolants. U-shaped heat equalizers are disposed around the insulated material to conduct ambient heat leakage directly to the coolants and thereby help to insure a uniform temperature throughout the product storage box.Type: GrantFiled: July 9, 1992Date of Patent: May 23, 1995Assignee: UTD IncorporatedInventors: Eugene L. Foster, Mavis H. Foster

Patent number: 5193628Abstract: A method and apparatus are disclosed for determining the position of a centerline of a passageway by using a measuring instrument which passes through the passageway taking periodic and successive axial strain measurements which are in turn used to form an interconnected series of circular arc segments representing the centerline.Type: GrantFiled: June 3, 1991Date of Patent: March 16, 1993Assignee: UTD IncorporatedInventors: John L. Hill, III, Eugene L. Foster, William J. Hutzel
