A self-amplifying safety brake for a disc is provided. The brake includes: a housing; a spring assembly oriented perpendicular to an axis of rotation of the disc, the spring assembly including a first spring end and a second spring end; a sleeve assembly co-axially housing the spring assembly, wherein movement of the sleeve assembly in a first co-axial direction compresses the spring assembly at the first spring end and movement of the sleeve assembly in a second co-axial direction decompresses the spring assembly at the first spring end; a spring compressor configured to move the sleeve assembly in the first and second co-axial directions; a brake plate for frictionally engaging the disc; a lever-cam assembly associated with the sleeve assembly and the brake plate, the lever-cam assembly configured to translate movement of the sleeve assembly in the first coaxial direction into movement of the brake plate away from the disc.

A torque wrench is provided. The torque wrench has housing and a rotating assembly rotatably mounted in the housing. The rotating assembly has a gripping assembly with an aperture for receiving a tubular and a plurality of die assemblies; a bevel pinion carrier assembly with a bevel pinion carrier and a bevel pinion mounted in the bevel pinion carrier; an upper ring gear fixed to an upper bevel gear rotatably connected to the bevel pinion at an upper side of the bevel pinion carrier; a lower ring gear fixed to a lower bevel gear rotatably connected to the bevel pinion at a lower side of the bevel pinion carrier; and first and second members threadably coupleable with each other, the first threadably coupleable member fixedly connected to the bevel pinion and the second threadably coupleable member drivingly connected to the die assembly, wherein rotation of the bevel pinion drives the die assembly toward and away from the tubular.

Spinning torque wrench

A luminaire () comprises at least one elongate luminaire housing (), a plurality of lens segments () extending through the at least one elongate luminaire housing, the lens segments having at least one edge which is cut on an angle, wherein an adjacent edge of adjacent lens segments form supplementary angles, at least one end constraint at ends of the plurality of elongate lens segments, at least one temperature compensation unit () disposed between ends of the plurality of elongate lens segments.
