20080279541 | Optical Device and Light Source - An optical device directs light from a light source to a region of space, such as the field of view of a camera when the optical device is used as a camera flash unit. This device includes a first optical element which converges light from the light source towards an inner portion of the region to be illuminated and a second optical element which diverges part of the light from the first element outwardly towards an outer portion of the region to be illuminated so as to achieve adequate central illumination with improved uniformity of illumination across the region to be illuminated. The second optical element may have a concave multiple-faceted surface comprising plane facets in the shape of an open-base inverted truncated pyramid, contiguous sector-shaped facets, at least some of which are concave, or a face divided into an elongate portion disposed between first and second diverging portions. | 11-13-2008 |

20120234634 | COIL SPRING RAIL BRAKE - A rail brake includes a rigid enclosure which mounts under a crane so as to dispose the base end of the enclosure over and adjacent a rail. A top plate is mounted underneath the upper end of the enclosure. A spring carriage is mounted for vertical translation within the enclosure, beneath the top plate. Springs are mounted between the spring carriage and the top plate so that the springs are compressed when the spring carriage is elevated. A brake shoe is mounted under the carriage. Actuators are mounted between the spring carriage and the base end of the enclosure. Extension of the actuators compress the springs and elevate the brake shoe from the rail. Retraction allows the springs to drive the brake shoe against the rail. An opening in the enclosure allows replacement of the springs and actuators. Elevation of the brake shoe provides for its inspection and maintenance. | 09-20-2012 |
20120241262 | VERTICAL RETRACTABLE RAIL CLAMP - The rail clamp includes a carriage having an actuator frame mounted to its base so as to extend upwardly from the base. Springs are mounted in the actuator frame at the upper end of the carnage. An actuator is mounted between the base and the springs. A wheel is mounted on a wheel support. The wheel engages the rail. At least one suspension frame is pivotally mounted to the carriage and at an opposite end, to the wheel support. The actuator operates on the suspension frame so as to elevate the carriage. A pair of clamping levers is pivotally mounted to the base of the carriage. Brake shoes mount on the lower-most ends of the levers. The levers are pivotable so as to clamp their lower-most ends together when their upper ends are moved apart. | 09-27-2012 |
