As shown, the laminations 58 are cone-shaped and the core has stub shafts 62, 65 at both ends. The core is covered with a layer of synthetic resin 68, Fig. 6, on which the armature coils 67 are surface wound and secured by glass binding or yarn 71 and a coating of insulating varnish 72. Stub shaft 62 carries the commutator 70. Figs 1 and 2 show a machine incorporating the rotor and which has a laminated stator shell 12 to which two pairs of permanent magnets 13 are secured, each pair extending inwardly to form a single pole. Insulated conductors 35, 35<SP>1</SP>, 37 extend between the magnets and are connected by end rings 38 to form a squirrel cage damping winding. Additional damping is provided by non-magnetic inserts 39, 40 in the shell 12. In a modification, Fig. 3 (not shown), each pole comprises three permanent magnets. The machine casing has entry and exit apertures 29, 30 for cooling fluid and the spaces between the permanent magnets are closed by baffles 22, 24 and (55), (56), Fig. 4 (not shown) which direct the cooling fluid over and around the rotor.

Abstract: 879,834. lon-exchange. PERMUTIT CO. Ltd. July 30, 1959 [Aug. 8, 1958], No. 25540/58. Class 46. In a pulsating ion-exchange bed process in which a pulp, e.g. a uranium or gold pulp, is exchanged with a bed of resin beads, the pulp is introduced through pipe 9 into the bed at such a rate that the resin introduced at pipe 12, when it is fully loaded with exchanged ions from the pulp, will not pass through the interface in the conical part of the vessel 25 and will be withdrawn by collecting device 14, but the pulp will pass through the interface to be discharged at pipe 18. The pulsating effect is produced by magnetically controlled supplies of compressed air into space 19. Other methods of introducing the pulp are described in Figs. 4 and 5 (not shown).

Abstract: 1318272 Automatic tracing apparatus IWATSU ELECTRIC CO Ltd 29 May 1970 [31 May 1969] 25973/70 Heading G4H In automatic tracing apparatus in which the pattern to be followed is traced by a series of closed path scans 51, 52, 53, 54 (Fig. 8) in which the direction of tracing is determined by the point of intersection of the curve and scan path, a minimum value detector 123, (Fig. 7) selects a tracing direction having a minimum difference with respect to the previous tracing direction and a difference less than a value set by a limiter 129 so that whilst intersection points corresponding to the previous trace directions are found, i.e. points pal, pbl, pc1 in Fig. 8, points corresponding to other trace directions i.e. pb3, pc3, pc4 are not followed until a point corresponding to the previous tracing direction is not found. This enables branch points (Fig. 6, not shown) and bends of the curve to be distinguished. In Fig. 8d no intersection is found within 90 degrees of the direction 50 and consequently the intersection pd2 is judged to lie on on a bent portion of the curve. The next trace is then selected to be to the right of the intersection pd2.

Abstract: 1318088 Selecting frames from microfilm IWASAKI TSUSHINKI K K 1 June 1970 [11 June 1969] 26302/70 Heading G4H A system for searching out a desired frame from a moving microfilm 7 comprises a screen 10 on which the frames are successively projected and two groups of photosensitive detectors 11 which detect an image 13 of a mark associated with each frame. The detectors, which comprise photo transistors, are arranged in two groups of three detectors and the image 13 of the mark associated with each frame is reflected from a mirror 9 on to the detectors. The detectors are connected to a logic circuit comprising AND gates and bi-stables and the mark images 13 have a longitudinal extent equal to the length occupied by each group of three detectors. When both the first and then the second groups have been covered by the mark image, the logic circuit emits an "add" counting pulse and an "add" instruction signal. As long as the film travels in the same direction the "add" instruction is maintained and pulses due to the passage of each frame are counted. If for any reason, for example due to a speed change, the film undergoes a directional change involving the passage of one or more frames in the opposite direction, a "subtract" counting pulse and a "subtract" instruction are provided by the logic circuit.
