The end cap has a cylindrical skirt portion and an end piece, a plurality of inwardly-directed latching tabs spaced around the cylindrical skirt portion and which are springingly deflectable in a radially outward direction when the latching tabs are forceably urged over the corrugated conduit open end. The latching tabs spring inwardly when the diameter of the corrugated conduit decreases, thereby latching the end cap over the open end. The end cap may further have an arcuate configuration for the end piece where the cylindrical skirt portion has an inside diameter greater than the outside diameter of the corrugated conduit. The end piece may also have an axially-directed aperture with a center not centered on the axis of the corrugated conduit.

Abstract: An apparatus for leveling and smoothing a substance such as concrete and drawing up paste in one motion. The apparatus has a leveling blade with a straight edge and a smooth-surfaced float. The float attaches to the leveling blade by a connecting strip of resilient material, which permits the position of the float to contour to the concrete surface. The connecting strip, adjacent to the float, contacts the concrete surface to pull up cement paste, which creates a more workable surface. The leveling blade attaches to the handle by a mount. The mount and handle are adjustable to add additional length to the apparatus for use on various sized concrete surfaces. A vibratory mechanism can also be attached to the apparatus to assist in leveling and smoothing concrete.

Abstract: A spectrometer, or a spectral instrument using multiple non-interfering optical beam paths and special optical elements. The special optical elements for use with the instrument are used for directing the optical beam and/or altering the form of the beam. The instrument has the potential, depending upon the totality of the optical components incorporated into the instrument, to be a monochromator, a spectroradiometer, a spectrophotometer and a spectral source. The spectral instrument may further be a part of the spectral system. The system may include the spectral instrument, a power module and means for remote control of the instrument. Such remote control may be by use of a personal computer or a control system dedicated to the control, measurement and analysis of the collected information. The multiple non-interfering beam paths are created using specially designed optical elements such as a diffraction grating, a splitter box, a zero back-lash drive system for movement of the grating element.

Abstract: Systems for leaching liquid waste, particularly waste water. More particularly a cylindrical conduit or pipe for use in leaching systems. The pipe further has axially directed cuts or apertures in conduit/pipe valleys, has ridges, channels and grooves over which may be laid either single or multiple layers of fabric. The corrugated pipe may have slots or slits or V-grooves in and on the various portions of the pipe such as the outer-facing surface of the ridges, the end portion of the ridges, the side wall of the groove or through the bottom portion of the groove, i.e., the valleys. The cylindrical conduit disperses moisture away from the conduit through capillary action, wicking into a surrounding material. A perforated cylindrical conduit is one method permitting wicking. The surrounding material provides capillary action to transmit moisture away from the cylinder or conduit. These surrounding materials include sand, gravel, plastic fibers, wood products, slag, and ash.
