Abstract: Systems and methods for improved stereolithographic (SLA) three-dimensional printing are provided. The systems and methods utilize an array-lens to produce kaleidoscopic imaging patterns, which in turn are used to direct the curing of resin to produce a three-dimensional object. The array-lens can be used to replicate, superposition, and/or overlap or otherwise reconstruct an image received by the array-lens, onto a resin that is used to form the desired object. The systems and methods can further use an optical diffuser, with a distance between the optical diffuser and the array-lens being adjustable to provide a desired kaleidoscopic imaging pattern on the resin. Additional features and methods for use with the provided SLA three-dimensional printing systems and methods are also provided.

Abstract: A power strip for covering cables, cords and wires includes a row of segment covers together containing channels with channels for the cables. The opposite ends of adjacent covers are hingedly connected. A coupling is swivelably connected between each set of adjacent ends of the covers. Coupling channels in each coupling complete the cover channels. A diversion tunnel from a coupling channel and out the lateral side of the power strip for diversion of cables out of the power strip.

Abstract: Each spaced apart support for a cable run in a preferred form includes a hook having a relatively narrower width along the direction of the cable run. A respective extender attached above each hook has a greater length along the cable run than the width of the support in the direction of the cable run, and the extenders thereby provide extended support for cable resting on the extenders along the cable run. Each extender has a slight downward curvature. The opposite ends of each extender have a sharp downward curvature so that the extenders will support resting cable passing over the supports and avoid damage to the cable passing off the extender. A plurality of the supports may be spaced apart at a greater interval such that the longitudinal ends of adjacent extenders are spaced apart defining an acceptable length gap over which the cable run passes.

Abstract: A cable dropout for a cable tray: The cable tray has side rails. Rungs at spaced intervals along the side rails define the width of the tray with the side rails. The tray side rails have laterally outward extensions at the bottom regions of the side rails for mounting a cable path re-directing dropout to the tray. The dropout has a convexly curved surface for redirecting and supporting a cable from its path on the tray to below the tray. A mounting bar at the entrance region of the dropout from the tray has laterally outward extensions clamped to the bottom region outward extensions at the bottom region of the side rails, so that the mounting bar may be clamped at any location along the side rails.

Abstract: A cable raceway including top and bottom walls, rear and front walls and a divider extending along substantially the entire length of the raceway. The divider extends in the direction between the top and bottom walls of the raceway. The raceway is comprised of a rear module of the raceway and the next module outward is a front module completing the preceding module passages. A cover over the front module passage completes that passage.

Abstract: A cable support hook of a general “J” shape with a rear leg, a front leg and a web joining the legs. A platform at the top of the rear leg extends parallel to the web. Slides at the top of the platform of a hook below may be received in rails at the bottom of the web of a hook above and the hook below is slid rearwardly along the guidance provided by the slides and the rails to stack the hook below beneath the hook above. No additional fastenings between the hooks are required.

Abstract: A combination of a cable raceway and a power device box where the cable raceway includes at least one and usually at least two compartments extending along a length of the raceway. The power device box includes a base unit. The compartment of the cable raceway includes a removable cover forming a wall of the raceway. The base unit extends over the compartment of the raceway and is secured to the raceway. A power device box base unit receives cables from the raceway.

Abstract: In cable tray, particularly cable tray with a central spine and laterally projecting arms, a bracket secured to the top and the bottom ends of the spine for holding a device in place through which cable runs. The bracket includes an inclined front face side that hooks to the top of the spine and a second horizontal side that attaches at the bottom of the spine and an opening through the inclined face of the bracket provides access to the device supported in the device.

Abstract: An expandable raceway for electrical wiring is constructed of a main section which defines a main passage. In cross-section the main section includes a leg and parallel arms that extend in the same direction from opposite ends of the leg. Each arm is provided with an indexing formation to receive a cooperating indexing formation along the free edge of an arm of an L-shaped auxiliary section for mounting the auxiliary section to the main section without dismounting from a surface to which it is already affixed or dismantling the main section. In cooperation with one arm of the main section, the auxiliary section defines an auxiliary passage outside of the main passage. The auxiliary section includes one arm parallel to the arms of the main section and one arm coplanar with the base of the main section and the latter arm includes the indexing formation thereon covers over the open sides of the sections.
