The invention discloses a method and an apparatus for creating an elementary optical disc master with but a single layer to be applied to a disc substrate to form pits having ideal shapes and without berm buildup. These ideally shaped pits are improvements in the technology of disc mastering, due to the manufacturing and data playback advantages that are inherent in the ideally shaped pits. An optically active lamina consisting of a dye polymer solution of nitrocellulose and a increased dye additive is spin coated directly to a pregrooved polycarbonate substrate to enable the recording of data on the disc by laser means in the form of pits. The pits are created by having a data modulated laser focusing on the optically active lamina which reacts to the irradiation causing a pit to be formed. The resulting pit more often than not possesses a residual raised berm area surrounding the pit, in what is considered to be a less than ideal shape for a pit. The residual berm, however, is eliminated by an additional process and step of passing the recently recorded disc under a UV illumination source before application of a final conductive layer to the disc.

A method of killing or controlling vegetation particularly along roadside berms involves the application of pressurized hot water from a moving applicator head in close proximity to the ground. The pressurized hot water is applied as jets of hot water from an applicator head at a temperature in the range of 100 DEG C. to 110 DEG C. and the flow rate of about 10 liters/minute supplied from one or more pumps operating at a pump pressure of between 200 to 100 psi. The apparatus is mounted on or in a vehicle such as a van, containing a water tank (1), a boiler (2) arranged to heat pressurized water supplied by a pump (4) under pressure to the boiler (2). The pump (4) is a piston pump which supplies the pressurized water through the boiler to a hand held applicator (5) or optionally a towed boom applicator (6). The hand held applicator (5) has an applicator head inside a shroud so that the pressurized hot water is applied to the surface of vegetation as jets of water within the confines of the shroud.

A closed photo-bioreactor, which in at least one example comprises a plurality of flexible, repeating, substantially enclosed, parallel chambers flexibly connected along their lengths, where a liquid growth media is substantially still without the need for turbulent mixing of the bulk liquid. In many examples, each is connected into integrated, flexible pipelines that serve to supply gas to the chambers, to vent gas from the chambers, and to fill and drain the individual photo-bioreactor chambers of their liquid contents. In some installations, a bioreactor will be rolled up using, for example, a long rod as a spool, for storage and transportation. Some examples will be manually unfurled and positioned on an angled site including, for example, an earthen berm. In many embodiments, a photo-bioreactor will be manufactured from thin plastics using low cost manufacturing techniques. In at least one example, a photo bioreactor is described in which bubbles with a substantially non-convex shape are introduced to mix the liquid contents.

Effective techniques and equipment are described for maintaining and improving dredge disposal sites. In one aspect, the use of winching equipment is described to move a digging vehicle within a containment area for effective creation of ditching to permit substantial dewatering and drainage of the dredge spoil to dry it. Substantially dried spoil is removed from the containment area pit using amphibious scraper equipment. The substantially dried spoil may then be used to build up the berm surrounding the dredge pit.

Images are projected onto two adjacent screens whereby one screen is movable with respect to the second screen. A projection system disposed generally in front of the two screens is capable of displaying images on each screen independently when the two screen are in an “open” position or on both screens together when the two screens are configured in a “closed” position. In a first “open” configuration, the images viewable on one screen are not viewable to the viewers of images on an adjacent screen and, in a second “closed” configuration, images are displayed on both screens together so as to be viewable by all members of the audience. In addition, a berm is configured between the viewing area of one screen and the viewing area of the other screen to create an audio and visual barrier between the two screens.

A system for containing and managing fluids produced at a work site, such as an oil or gas drilling site, includes one or more fluid containments formed as a basin for collecting and retaining fluids, a berm forming a perimeter of the containments, a layer of sand placed over each basin, a fluid-impermeable membrane placed over the layer of sand, and drainage stone placed over the membrane, filling the basin. A geotextile fabric can be placed over the membrane to help protect the membrane from adverse affects of the drainage stone. A leak detection system can be coupled with the membrane to identify potential leaks in a containment system. One or more catch basins can extend through the basin and the drainage stone filling the basin, to receive fluids. A drainage system is placed in fluid communication with the catch basins to drain fluids from a containment.

A strip tillage implement includes a single, center-mounted arm located directly above the row area of a strip-till berm. Basket halves are rotatably connected to opposite sides of the arm in cantilever fashion to eliminate outer support arms. Residue flow encounters rolling baskets rather than fixed arms so that catching, flipping and twisting of residue is minimized and plugging in high residue conditions is reduced. A single, center-mounted bearing and simplified basket halves reduce the cost and complexity of the implement.
