Abstract: The present invention relates to a method for assembling a dummy aeroplane in which a latticework carcass is constructed from the components of an assembly kit and covered with a weatherproof drape. The inventive method is characterized by the sequence of steps in which the upper parts of the carcass, or shell, are assembled at a first level, whereafter the assembled upper part is raised to a second level with the aid of lifting devices and held at this level by the lifting devices while lower parts of the carcass are assembled. These steps are then repeated until the undercarriage of the dummy aeroplane has been fitted, whereafter the lifting devices are withdrawn so that the dummy rests on its wheels, all of this assembly work being carried out at a level suitable for the assembly personnel concerned.The invention also relates to an assembly kit for carrying out the method.

Abstract: The product of the invention is a plastic tape, for example pressure sensitive plastic adhesive tape, which can easily be manually torn, as from a supply roll, without the use of any tool. At least one edge of the tape is provided with a series of closely spaced points of weakness by cutting or tearing therein shallow slits or notches at which tearing can be easily initiated. Such points of weakness may be formed in the tape prior to rolling into a supply roll or may be imposed by working the flat side of a roll with sharp grit sandpaper or the like or by cutting means.

Abstract: Data reorganization apparatus includes a double buffer arrangement in which data is written into each buffer by rows and is read out by columns. The inputs and outputs of the buffers are time-division multiplexed, which reduces the required width of each buffer by the product of the input and output multiplexing factors. The apparatus can be used for corner turning of image data e.g. receiving data in sub-frame order and reorganizing it into scan-line order for display.

Abstract: A dispenser for use, for instance, as a rumen bolus is a generally cylindrical container (1) for material to be dispersed into the digestive tracts, etc. of a ruminant. The container has a closure (3) held in place by a controlled release glass (CRG) member (5). When this member is dissolved, the closure (3) comes out and the contents are released. The cylindrical container can be formed by a hole in a larger member which has several such holes so that different materials can be released, or materials released at different times.Variants include stacked arrangements in which several dispenser compartments are coupled so that as one is emptied a CRG member is dissolved to release material in the next compartment.In some cases the CRG member acts both as the release device, and as the closure for its compartment, and in others it also acts as a means of linking a number of detachable sections.
