A pre-form and a method of preparing pre-forms are provided. The pre-forms comprise a resin and at least three layers of oriented fibre tows. The pre-forms comprise fibre tows instead of the traditional prepregs to enhance rearranging of resin and / or fibres during subsequent processing as well as provide greater freedom, a price reduction and / or a reduction of waste. The pre-forms may be formed three-dimensionally to enhance coupling to further pre-forms or other structures and / or to enhance shaping of the pre-form to a final three-dimensional shape. The method of preparation of pre-forms involves providing an adhesive between layers of fibres and providing a resin in contact with at least one of the layers of fibres. The resin is preferably provided in a non-continuous layer to allow for removal of gas at least partially in a direction orthogonal to the layers of resin. Advantageously, during manufacturing, the fibres are placed with an exact start and ending location, thereby avoiding waste. The pre-forms are suitable for preparation of composite structures like for example spars for wind turbine blades.

Method and apparatus for facilitating a sales transaction between one or more sellers and potential buyers in relation to large numbers of similar units. A seller offers the units to buyers, starting at an initial price. The potential buyers make offers to buy a given number of units at that price. The price is incrementally reduced, with buyers being given the opportunity to bid with each reduction. In other embodiments, the buyer makes an offer to multiple sellers at a given price, specifying the number of units the buyer wants. Sellers offer to fulfil some or the entire offer, and the buyer subsequently reduces the price and makes additional offers until the buyer's requirements are met.

An object of the present invention is to provide a light diffusion sheet having a favorable cost reduction capability due to excellent scratching preventive property of the front face, and having in addition thereto, a favorable directional light diffusion function, transmittivity of rays of light, and a thin film character; and a backlight unit capable of promoting performances such as luminance as well as price reduction, and thin and light modeling capability. The light diffusion sheet of the present invention has a light diffusion sheet including a transparent substrate layer, and a light diffusion layer overlaid on the front face side of the substrate layer, wherein the light diffusion layer has resin beads and a resin binder, characterized in that the light diffusion layer has protruding parts having a shape of a partial spherical body on the front face in a scattering manner. It is preferred that mean height of the protruding parts be 1 mum or greater and 10 mum or less, mean diameter of the protruding parts be 4 mum or greater and 18mum or less, mean occupancy rate of the protruding parts be 2% or greater and 20% or less, and surface roughness (Ra) of the light diffusion layer be 1.5 mum or greater and 10 mum or less. As the beads, small monodisperse beads as a principal component, and large beads as a sub component may be included.
