Abstract: Flexible diffuse-reflective smart camber (FDRSC) devices are disclosed herein. The devices include UV-C lights sources and an irradiance chamber. The irradiance chamber is open on at least one end through which the plants to be treated are exposed to the UV-C irradiance. Further, the inner surfaces of the irradiance chamber are covered by or consist of a diffuse reflective material that passively intensifies and uniformly distributes the UV-C irradiance to penetrate plant canopies. Also described herein are autonomous vehicles for moving the FDRSC devices across fields of crops and other plants. which is controlled in real time by a dosing control system. Also described herein are methods of in-situ UV-C treatment of plants using the FDRSC devices.

Abstract: The present invention is an insect screen with improved durability designed to serve the primary purpose of keeping out very small insects and pests while maximizing visual clarity, light transmission, and airflow. The insect screen is free from macroscopic permanent deformation when subjected to a blunt instrument deformation test of at least 5 lbs. and has a total light transmission of at least 65%. The inventive insect screen comprises fibers in a warp and fill construction which define openings having a warp dimension and a fill dimension, both of said warp and fill dimensions being equal to or less than about 0.06 inches and equal to or larger than about 0.01 inches, the fibers having a diameter less than about 0.007 inches.

Abstract: An insect screen made from fibers in a warp and fill construction defining openings having a warp dimension and a fill dimension, both of said warp and fill dimensions being equal to or less than about 0.04 inches and equal to or larger than about 0.01 inches, said fibers having a diameter of equal to or greater than about 0.002 inches and less than about 0.007 inches. The present invention is an improved insect screen designed to serve the primary purpose of keeping out very small insects and pests while maximizing visual clarity, light transmission, and airflow.

Abstract: An insect screen comprising fibers in a warp and fill construction defining openings having a warp dimension and a fill dimension, at least one of the warp and fill dimensions being less than about 0.05 inches and the other of the warp and fill dimensions being larger than about 0.03 inches, the fibers having a diameter of equal to or less than about 0.007 inches. The present invention is an improved insect screen designed to serve the primary purpose of keeping out insects and pests while maximizing visual clarity, light transmission, and airflow.

Abstract: In conventional audio disc playback apparatus the pick up arm is mounted on the turntable baseplate. Thus, the pick up arm is subject to vibration produced by the rotation of the turntable and its associated motor.Sound reproduction apparatus comprises a turntable 1, a pick up arm 2 and clamp apparatus 3 for attachment of the pick up arm 2 to a wall 4. The clamp apparatus 3 comprises a wall mounting bracket 5, a length adjustment tube 6, a distance bar 7 and a pick up arm clamp fork 8. Locknuts 9a, 9b and 9c are also provided and the clamp fork 8 has a pair of lockable adjusters 10.In use, the wall mounting bracket 5 is fixed to a wall by way of screws. The length adjustment tube 6 is attached to the bracket 5 and the distance bar 7 and locked in position by locknuts 9a and 9b. The clamp fork 8 is fixed to the distance bar 7 and the pick up arm 2 is fixed to the clamp fork 8 by way of the lockable adjusters 10.
