Abstract: A device compensates for the movement of a cinematographic film moved continuously through a camera or projector. A plurality of separate inverting reflectors, typically Amici prisms (70), move in the same direction as the film (20) but at one half the speed of the film. The path of the prisms (70) is determined by a straight line segment (74) of a track (72), the staright line segment (74) being parallel to the direction of movement of the film (20). A separate coupling between each facet and drive means permits relative movement between the facets as the move around the path. 
     By illuminating the film over a width of at least one and a half frames using a condenser lens (18) so a number of partial images are obtained which are reconstituted in the optics so as to form in the projected image a composite frame which in general will be made up of two or three images of frame parts from two or three adjoining frames.

Abstract: Selective excitation is used to define a thick planar slab of excited nuclear spins in a nuclear magnetic resonance (NMR) imaging sample. The thick slab is selected such that the excited spins are contained well within the optimum sensitive region defined by the radio frequency (RF) transmitter and receiver coils. Three-dimensional spatial information of an NMR imaging parameter, such as nuclear spin density or nuclear spin relaxation time, is collected simultaneously from the excited slab and can be used to construct a series of several tomographic section images of the slab. The spatial information is encoded in the NMR signal by application of pulsed gradient magnetic fields subsequent to excitation. Image picture information is obtained from the NMR signals via three-dimensional Fourier transformation.

Abstract: In a television receiver for a transmission system in which the vision signal is scrambled to allow only for its authorised reception a vision signal processor (8) is provided in which the scrambled vision signal is de-scrambled. A low rate encrypted signal present at an output (11) of a sound/data signal processor (10) is decrypted and employed to periodically set (say once every one or two seconds) a master pseudo random pulse generator (12B) producing an output of pseudo random configuration at frame rate which is used to periodically set a vision slave pseudo random pulse generator (15) to produce an output of pseudo random configuration at line frequency. This is applied to an input S of the processor (8) and forms the scrambling keyforthe line-by-line de-scrambling of the vision signal.The sound/data components, which are packet multiplexed, are also scrambled at packet rate to allow only fortheir authorised reception, the sound/data signal processor (10) additionally performing the descrambling of the sound/data components. The output of the master pseudo random generator (12B) is also used to periodically set a number of slave pseudo random pulse generators (17, 18, 19) which produce outputs of pseudo random configuration at packet frequency applied to input S1, S2, S3 of the processor (10) and which form the respective scrambling packet keys for the de-scrambling of the scrambled sound/data components. The advantage obtained is that a low rate encryption key need only be transmitted to produce the required scrambling keys for both vision and sound/data.
