Title: Methods of indicating nuclear spin density distribution
IPC: G01R33/48
Filed: 1980-02-29
Abstract: Spin density distribution in a sample subjected to a static magnetic field along a y-axis is determined by subjecting the sample to an initial magnetic field gradient Gz to the static field together with a 90 DEG  selective rf pulse to excite spins in a selected strip. The Gz gradient is then replaced by a filter gradient Gx varying in a direction normal to a selected slice in the strip, for a limited period of time during which the free induction signal only partially decays. The filter gradient is then immediately replaced by a read gradient Gy (varying in a direction mutually orthogonal to Gx and GZ) and the free induction decay signal is measured. The sequence may be repeated cyclically with a delay between each cycle. <IMAGE>

Patent GB-2084720-A (GB)
Title: Measuring fluid flow
IPC: G01F1/66
Filed: 1980-09-30
Abstract: A fluid flowmeter measures flow velocity by detecting the eddies that are present in all moving fluids. A light beam transmitted through the fluid from a source 11 to a detector 12 is refracted by the passage of eddies therethrough this causing corresponding changes in the detector output. By using a split detection arrangement the velocity of the eddies and hence that of the bulk fluid is then determined. In an alternative arrangement a single detector is employed and the fluid velocity is determined from the frequency at which the eddies pass through the light beam. <IMAGE>

Patent GB-2062934-A (GB)
Title: Tape recorder
IPC: G11B15/44
Filed: 1980-10-10
Abstract: The required operational state of a tape recorder, which may be an automatic reversing cassette tape recorder, is selected by manual keys 53 (Figure 8) and established under control of an electronic control unit 54 by motor 50 driven cam means 44 which moves the various mechanical parts to the appropriate position. Cam 44 has cam surfaces to operate forward and reverse pinch rollers 8, 9, reel brakes 45b and a plate 47 carrying heads 5, 6, 7. A CPU in control 54 has inputs from manual keys 53, record/reproduce dectector 56a, reel rotation detector 56b, and a cam detector 56c and gives outputs to a driver 55 controlling the direction of cam motor 50 and the direction and speed of reel motor 26. Motor 26 drives an idler gear 31 on a lever 29 which via friction means is caused to swing and engage gear 31 with the appropriate reel shaft 3 or 4 in accordance with the direction of rotation of motor 26. Cam 44 can establish fast forward and reverse, forward and reverse record/reproduce, and pause in the forward and reverse state, and detector 56c comprises a cam position indicating switch 52 (Figure 7). A cam rotation direction memory switch 154 (Figures 12, 13) may also be provided to ensure proper recording operation even if a timer is used to restart the recorder after autoreversing has been effected in the previous recording operation. If the CPU senses overrun of cam 44 past the desired position, it effects a cam reversal sequence until the correct position is achieved. An alternative embodiment (Figures 18-21) in which the reel brakes 234 are mounted on the movable head plate 203, has a first cam wheel 236 to move head plate 203 and forward pinch roller 215, and a second cam wheel 235 to move reverse pinch roller 216. This recorder can be simply changed from an auto reversing two recording/reproducing direction type to a unidirectional recording/reproducing type by omitting cam wheel 235, pinch roller 216 and associated components. <IMAGE>

Title: Reversible paper feed for an X-Y plotter
Inventor: JACKSON MICHAEL GEORGE
IPC: B65H20/20
Filed: 1981-07-22
Abstract: Improved accuracy in plotting in an X-Y plotter is obtained by means of a slightly resilient layer of polyurethane on the surface of the platten (7) and two sets of locating sprockets (8) near the extremities of the platten (7). A pair of vacuum chambers (13) to either side of the platten accommodate slack folds of paper on the entry side and on the exit side of the platten and introduce a controlled tension in the paper without adding parts subject to high acceleration whose collective inertia is to be minimised. This tension is sufficient to improve the frictional coupling between the platten surface and the paper. <IMAGE>

Patent GB-2097137-A (GB)
Title: Visual recording method and apparatus
IPC: G03B37/04
Filed: 1981-12-17
Abstract: The method according to the invention consists in producing an image on a data receiver, e.g. a film strip, without perspective distortion or with constant perspective distortion, by scanning of a data carrier, e.g. a subject, at constant speed via slits, by means of an e.g. optical or electronic lens system. To this end, the subject A is moved past the pair of slits 60,70 of the optical system at a first constant speed with respect to said pair of slits, whereas the film strip 100 is moved past the optical system at a second constant speed with respect thereto. Three intrinsically distortion-free images D,S1,S2 of the scanned subject A originating from corresponding different directions of sight may be produced at the same time by utilising three pairs of slits 60a, 70a; 60b, 70b; 60c, 70c delimiting a different section of the angle of illumination of the optical system in each case, in conjunction with separately co- ordinated but equi-directionally or synchronously driven film strips. It is particularly appropriate for continuous three-dimensional photography of terrain sections or operating actions. <IMAGE>
