Patent EP-0260998-A2 (EP)
Inventor: BARTON NICHOLAS
IPC: H04N13/00
Filed: 1987-09-21
Abstract: In a method of processing a video signal to provide digital video effects, an image signal is provided with an accompanying reference signal or Z-axis signal representative of the instantaneous distance of the scanning point of the video raster from an imaginary plane to be depicted as containing said information, taken in a direction perpendiculr to the image screen. This reference signal may then be utilised to produce a variety of effects. For example a circuit for super­imposing sets of image information to give the impression of an overlap in three dimensional space may comprise an order sorting circuit (1) having inputs (2,3,4) for sets of signals comprising picture information (P) a key signal (K) and a Z-axis signal (Z). At outputs (5,6,7) of the circuit the sets of signals are sorted into order of priority dependent on the magnitude of the Z-axis signal (Z). The picture signals (P) are mixed by multipliers (25,26,27) and a summer (28) to provide a composite picture signal in which the mixing of the components is determined by the multiplication factors of the multipliers (25,26,27). These factors are derived from the key signals having corresponding orders of priority, the key signals of lower order of priority being correspondingly attenuated by cascaded attenuators (12,13,14) coupled between lower order outputs of the sorting circuit (1) and a weighting circuit (11) for controlling the multipliers (25,26,27).

Abstract: A method of securing a plurality of replaceable segments (6, 7) to a base (2) wherein a plurality of deformable supporting members (1) are releasably fastened to the base (2) and wherein co-operating means (3, 4) are provided on a rear face of the segments and on the supporting members, the arrangement being such that the means connecting the supporting members to the base are also used to cause the means on the supporting members to engage with the co-operating means on the rear of the segments. 
     While it is envisaged the invention could be used for securing any working surface to a base member, the invention is particularly suited to securing replaceable segments on a rotary work member and also has particular utility in the textile field for connecting staves to a base roller or the like.

These resins are applicable for the analysis and purification of molecules of biological origin, in particular as a stationary phase in ion-exchange and affinity chromatography, especially for carrying out the fractionation of protein mixtures. Their interaction with proteins, in particular the anti-DNA and anti-phospholipid antibodies present in the serum of patients suffering from SLE, makes them applicable to operations for the selective purification of the different types of antibodies developed by lupus patients.

Abstract: In radial ventilators with an electric motor arranged in the impeller hub, there is a dependence between the motor and impeller diameters which determines the maximum possible air throughput for a predetermined impeller diameter. The object is, therefore, to provide a ventilator arrangement which, whilst having the smallest possible diameter, achieves an air delivery capacity increased in comparison with known versions. The electric motor is designed as an external rotor motor mounted on one side and having a central axle which is retained on one side and on which the stator stack is fastened and a common bearing arrangement for the outer rotor and the impeller is arranged. The central axle is assigned to the stator stack as a magnetically active component. The outer rotor is designed as a permanent-magnet rotor. The ventilator serves mainly for ventilating the interiors of motor vehicles. <IMAGE>
