Abstract: A system and method to promote biological responses within incubated eggs using lighting devices within an incubation chamber. A light supporting device is installed within the incubation chamber in spaced relation to an incubation device housing a plurality of eggs. The light supporting device is positioned to direct light at pre-determined wavelengths into the interior cavity of the incubation device to irradiate the plurality of eggs to promote a biological response within the eggs.

Abstract: An insulating panel (1) comprises a first sheet (2), a second sheet (3) with an insulating foam (4) therebetween. The foam may, for example be a polyurethane foam, polyisocyanurate foam or a phenolic foam. The first and second sheets (2, 3) are metal such as steel, for example a galvanised or coated sheet. At least one reinforcing element (20) is provided within the insulating foam (body (4) and extends between the first and second sheets (2, 3). The reinforcing element (20) extends longitudinally along at least part of the length of the panel (1). For enhanced structural strength there are at least two reinforcing elements (20) which are spaced-apart between the side marginal edges of the panel (1). The reinforcing element (20) comprises a first flange (21), a second flange (22) and a web (23) extending between the flanges. The reinforcing element (20) is adapted to interengage with the insulating foam body (4) during manufacture.

Abstract: A horticultural system having lighting elements pulsed with an off time proportional to the turnover time of the photosynthetic electron transport chain. The lighting elements emit light at a wavelength within 20 nm of a peak absorption of the pigment of the plant and are controlled to provide light at predetermined intervals as needed by the plant cause photosynthesis and reduce excess unproductive light.

Abstract: A roof panel (1) for use in forming a low pitch or flat roof comprises a profiled inner liner or decking sheet (2), an outer waterproof membrane (3) and a body (4) of insulation between the inner liner (2) and outer membrane (3). The membrane liner sheet (3) has a backing such as a fleece or scrim to aid adhesion of the membrane (3) to the foam body. The membrane (3) comprises a side lap (5) extending sidewardly of at least some of the marginal edges of the body (4). The inner liner (2) comprises joint formations for forming a nested side lap joint between adjacent panels. The joint formations comprise a first joint formation (20) at one edge of the liner (2) and a second joint formation (21) on an opposite edge of the panel. The first and second joint formations (20, 21) of adjacent panels are adapted to interengage on assembly and are clinched together using a clinching tool (22) to form a clinched joint (25). The first joint formation (20) comprises a liner extension which is shaped to define a recess.

Abstract: An end cap comprises a base and at least one finger extending in a first direction from the base. A plurality of sets of flexible fins can be provided, each set of fins comprising first and second fins extending generally from the finger in an orientation that is generally orthogonal to the first direction. Each set of fins can be being positioned longitudinally along an axis oriented generally in the first direction wherein the first and second fins are movable independently of each other. The first and second fins are resiliently displaceable and movable generally in the first direction. The first and second fins can be resiliently displaceable. The end cap can be used in association with a construction member whereby the finger is inserted into the channel. More than one such finger can be provided.

Abstract: An assembly comprises a supporting substructure and at least one longitudinally extending board member supported on the substructure. An edge member is mounted proximate an end portion of the board member and has a lower portion configured for attachment to the substructure, and an upstanding wall portion extending from the lower portion. The upper wall portion defines an open channel and provides an opening into the open channel. The edge member is attached to the substructure and the end portion of the board member is received through the opening of the edge member into the open channel. The channel can accommodate longitudinal expansion and contraction of the board member. The board member may be made of a natural fiber thermoplastic material. The assembly may be configured as a deck assembly.

Abstract: There is disclosed a reinforced extruded composite structural member and a method of forming the same. The structural may member comprise a solidified composite mixture of a fibrous material and a resin, and a reinforcing member embedded therein. The reinforcing member may have a known tensile strength, and at least one physical characteristic adapted to promote bonding of the reinforcing member with the surrounding fibrous material.
