    Abstract: 1,023,462. Circuits employing super-conductors. RADIO CORPORATION OF AMERICA. July 31, 1963 [Aug. 24, 1962], No. 30426/63. Heading H3B. [Also in Division H1] A super-conducting circuit for selecting the input to a three dimensional storage matrix comprises a large number of tree circuits, and one or two control elements for each set of corresponding tree branches so arranged that if the control elements are driven out of their super-conductive state all the corresponding branches are no longer magnetically shielded and therefore have a high inductance. As shown in Fig. 6, when control films such as 1-4 and n-4 are driven resistive by current applied at 114 they allow magnetic flux to pass through them and the tree branches 1c, 2c . . . nc have a high inductance. Thus by applying current to appropriate conductors 112,151, 153, 120 it also can be arranged for there to be only 1 low inductance path through each tree. To improve the switching rate of the control areas they may have a resistor connected in parallel of lower value than the resistive value of the film. In this way the film itself takes only sufficient current to drive it resistive (Fig. 4, not shown). The control areas may when super-conductive, shield the conductors from high permeability materials. The conductors and memory planes are preferably insulated with silicon monoxide. The high permeability materials should have little hysteresis at the operating temperatures but this is stated to include most ferrites and other normally square loop materials owing to the low operating temperatures. The use of only two control elements rather than one for each tree is stated to improve the switching speed. Lead and indium may be used as the super-conducting materials. The control elements may be changed from the super-conducting state by means of magnetic thermal, radiative or mechanical energy if desired.

    Abstract: 1,135,137. Fishing reels. SHAKESPEARE CO. 25 Sept., 1967 [17 Oct., 1966], No. 43619/67. Heading A1A. The reel has a spool manually rotatable through gear 19 and pinion 28 and is characterized in that the pinion is clutched to the spool shaft by pins 32 engaging in a slotted part 31 and is releasable from rotation with the shaft by movement of a slide 35. A projection 39 co-operates with a cam surface 38 of the slide whereby legs 36 of the slide move the pinion against a biasing spring 33 to declutch it from the shaft. Dogs 30 associated with the pinion co-operate with a projection 40 to move the slide and allow re-engagement of the clutch when winding-in is commenced. In an embodiment the projection 39 and cam surface 38 are replaced by a toggle linkage.
