Abstract: Although packing means for rolls of sensitive material, like light-­sensitive photosetting material, wound on a rigid core, shaped like stiff circular-cylindrical tubes with closing means and centering means for the roll at both ends are known, nevertheless still pri­mitive packaging is surprisingly used throughout. It results in damages of the material and difficulties during packing at the manufacturer, unpacking at the consumer, both in absolute darkness, and during storage. The invention solves all these problems by pro­viding tubes (7) cut at the required length, closing them with simple and reliable securing means (20), like bajonet fittings and standardised end-rings (8), fitted to the tube (7). Also stockholding of the packing-­parts for the manufacturer of the sensitive material is reduced considerably.

Abstract: A method of flow visualisation comprises the steps of coating the surface (15) of a component (17) in a pigmented oil-based paint (18) of non-geling characteristics, applying dry dye particles (19), which are soluble in the oil based paint (18) to the surface of the coating (15) and passing a fluid flow (20) over the component (17). 
     The fluid flow (20) causes the dye particles (19) to translate across the coating so that regions of the particles that are in contact with the coating dissolve to leave trails (22) on the surface of the coating which are indicative of the relative strengths of the fluid flows acting on the surfaces of the component.

Abstract: A friction facing material and carrier assembly (2) for inclusion in a clutch driven plate. The assembly (2) comprises a metal carrier plate (4) having resiliently pliable spokes or paddles (14) at its outer periphery. Two annuli (20,22) of friction material forming friction facings are bonded to opposite sides of the paddles (14) by a respective layer of an elastomeric material, for example a silicone rubber.
