Title: Arrangement for a switching matrix having diodes as linking elements
IPC: H03K17/76
Filed: 1976-04-23
Abstract: The parts of the assemblages of conductors (21 and 22) which cross over each other form the conductor system of the switching matrix. So that this can be put together out of few prefabricated parts to form a compact component with visibly and practically accessible connectors, the conductors (in the form of strips) of the assemblage (22) are taken between the rows of pegs (112), and thus parallel to the side (113) of the rectangle. This already means that the conductors are well fixed into the bearer. The steps (221) to the tapered ends and terminal lugs (222) join similar counterpart steps (9) of the projections (117), and similarly the steps of the tapered intermediate parts, by which the conductors (in the form of strips) are taken round the side of the rectangle of the base board (11) which is opposite the side (116), are joined to similar counterpart steps of the projections (117, 117') on that side, so that the assemblage of conductors (22) is perfectly fixed. The conductors (in the form of strips) of the assemblage (21) are not bent, and are taken between the rows of pegs (112') on the main surface (111') parallel to the side (116) of the rectangle. These conductors cross the parts (224) of the conductors of assemblage (22) which extend back parallel to the side (113) of the rectangle on the main surface (111'). The pegs (112, 112') are arranged congruently to each other on the main surfaces of the bearer base board, so that the ends (212) of the conductors (in the form of strips) of (21), which are taken over the side (113) of the rectangle in the form of connectors, are also congruent with the ends of the conductors of (22), which are bent at a right angle. <IMAGE>

In a change-speed epicyclic gearing applicable to bicycle rear hubs or bottom brackets, two or more gear ratios, one of which is direct drive, are brought selectively into action by a cam member rotatable co-axially with the main epicyclic gearing axis to cause engagement of a selected positively-acting clutch pawl with a toothed clutch rim appropriate to one gear ratio, and simultaneously to disengage or maintain disengagement of one or more clutch pawls and toothed clutch rims appropriate to the other gear ratio or ratios. As shown, the planet carrier 1, Fig. 2, and annulus 12 of an epicyclic train are alternatively connectible to a driving member 5, fast with a rear hub sprocket 4, by positive clutch pawls 8, 9, Fig. 1, pivoted on the member 5 and spring loaded to engage toothec clutch rims 28, 27 on the carrier and annulus for direct drive and geared underdrive respec tively. The carrier 1, which is rigid with a driven rear wheel hub 2, has rotatable thereon planets 34 meshing the annulus 12 and a reaction sun 35 fast with the fixed hub spindle. Contro of the pawls 8, 9 is effected by a cam ring 15, 16 engaging the member 5 by a flange 17 so as to be normally frictionally entrained thereby. The ring has thick and thin portions 15 and 16 coacting with the pawls 8, 9 to cause their disengagement from and to allow their engagemeni with the rims 28, 27 according to the relative position of the member 5 and ring 15, 16. During drive in a given gear ratio, a three-toothed pawl 22a on the ring 15, 16, though shown displaced thereon in Fig. 1, is actually so positioned as to engage in an appropriate one of two recesses 23, Figs. 1 and 3, in the member 5. To change gear, a pin a, Fig. 3, on an operating device (not shown) on the bicycle frame is moved into the path of a tooth 19 of the pawl 22a to turn the pawl into the position of Fig. 3a and station it and the ring 15, 16 until the pawl meets and turns into the other recess 23 tc allow the tooth 19 to escape from the operating device and the ring 15, 16 to be again entrained by the member 5. The change in the relative position of the member 5 and ring 15, 16 has meanwhile caused the pawls 8, 9 to interchange their bearing positions relative to the portions 15 and 16 and effect the gear change.
