Abstract: A mould for injection-moulding a plastic lid onto the tube of a package for liquid is described. The mould has an inner mould and a two-part outer mould (2, 7), of which two steel mould parts (2, 7) can be brought together in a sealing manner and moved apart along a parting surface (12) by control drives. In this arrangement, the injection-moulding cavity is formed by a surface contour construction (17), arranged on the mould parts (2, 7). On the side facing away from the injection-moulding cavity, cooling spaces (19) are provided behind the surface contour construction (17). 
<??>In order to improve the performance of the package-producing machine, in particular by improving the cooling of the moulding surface, it also being intended for less expensive moulds to be used for the injection-moulding cavity, the invention provides that the cooling spaces (19) are bounded on at least one side by an insert (9, 11) which is fastened liquid-tightly in a recess (20) in the respective mould part (2, 7).

Abstract: The method has two objectives:       1. Calculation of the probabilities of faulty operating states. 2. Calculation of the probabilities that an arbitrary system status A, present with a probability of p </= 1, generates a system status B which can be considered to be the consequence. This also provides the possibility for calculating the probabilities of causal chains. The method can be applied to diagnostics in humans, animals, plants and in technical systems and to determining causal relationships, particularly in pharmacology and epidemiology. A causal network is built up from simple components, for individual network nodes of which the probabilities of occurrence are calculated taking into consideration all relevant influences, particularly of mutual interactions of the network nodes. The numerical probability values needed for the calculations are obtained from samples, which are collected more favourably in each case under the condition of the presence of a real system status and for a limited network environment.

Abstract: A pump for pumping a fluid, eg for pumping water for a garden fountain or waterfall, comprises an electric motor (12) driving an impeller (32) in a pump chamber. The motor is an A.C. synchronous motor and on start up may rotate in either direction of rotation, only one of which is the direction in which the impeller (32) is designed to rotate. A sprag (46) pivotally mounted in the pump chamber is urged to a projecting position (Figure 3) by fluid flow if the motor starts in the undesired direction (48), and the impeller blades engage the projecting sprag, causing the impeller to recoil and thence to rotate in the desired direction of rotation (40), in which fluid flow maintains the sprag (46) against the wall of the pump chamber.

Abstract: A method is described for examining a propagative medium, such as a signal transmission cable, that requires the acquisition and examination of a minimum number of data points to determine the presence of an anomaly in the medium. When an anomaly is detected, its characteristics, such as location, type and amount of loss are determined. The characteristics are then displayed. If the anomaly is a reflectionless loss, the region containing the anomaly is examined repetitively to determine its location and to improve the accuracy of its location measurement. With each successive level of examination, additional samples are collected within the region. The new samples are combined with the existing samples to reduce random noise in the data. Through this method the location of the anomaly is re-determined with greater accuracy.
