Abstract: Portable and versatile X-ray or gamma imaging device for non-destructive examination of suspicious packages, integrating transmission and backscattering imaging. It comprises an X or gamma radiation source (4) adapted to radiography, a large and finely pixelated detector (6) sensitive to X rays or gamma rays adapted to radiography, a removable shielding and collimation accessory (5) to adapt the source to backscattering imaging, a removable accessory (10) comprising a large and finely pixelated coded mask placed in contact with the detector when a backscattering imaging or radioactive source imaging is made, and a synchronized control system (14) for the source, the detector and the latter accessory, and for data acquisition and processing to display an image in real time.

Abstract: An adjustable brake is provided that applies a braking force directly to an elevator sheave over which a cable suspends an elevator car and a counterweight. The brake includes a pair of calipers that apply a braking force to either longitudinal end of the sheave. The brake is spring set and may be released using, for example, electromagnetic, hydraulic or pneumatic forces. The calipers are mounted to and movable along a rail to enable adjustment of the location of the calipers. Further, the calipers are coupled together using one or more pins and are movable along the pins to enable adjustment of spacing between the calipers. The brake is particularly adapted for use with existing elevators because the brake does not require modification to the existing elevator sheave.

Abstract: The present invention concerns a variable-torque braking device. The device is characterized in that it includes a secondary control (14, 17) which allows exertion on a friction-lining pad (9) of an additional moving-system braking torque as a function of a variable command parameter which exerts on the friction-lining pad (9) a movable-system braking force or torque capable of linear variation, in addition to the constant braking torque or force furnished by a main control, as a function of the variable control parameter. The invention finds an application notably to braking forklifts.
