Patent ES-372584-A1 (ES)
Title: Monolithic electronic switching network having variable voltage levels
IPC: H04Q3/52
Filed: 1969-10-16
Abstract: In an end-marked self-seeking multi-stage crosspoint switching network, each matrix is a monolithic semi-conductor device and crosspoints of successive stages are adapted to fire at successively lower energy levels. The crosspoints may be PN PN diodes, each incorporating a Zener characteristic as shown in Fig. 4. The main feature of this characteristic is the flat top to the curve providing a constant voltage output with level and duration selected to operate a predetermined number of crosspoints of the subsequent stage, each subsequent stage being constructed to respond for a shorter duration and at a lower level than the previous stage. Each matrix comprises a substrate 50 having an epitaxial layer 51 grown thereon. Through successive oxidation, etch, and diffusion steps, a number of P and N layers are diffused into the epitaxial layer to form PN PN diodes. Conductors 52 are then chisel bonded to the diodes to form matrix connections. The efficiencies of the junctions in different switching stages is varied to provide the switching levels and the efficiencies of the junctions within a single PN PN diode may be varied to provide the Zener characteristic. The efficiencies of the junctions may be varied by varying the thicknesses of the individual layers of the PN PN diodes and by providing the epitaxial layer with an internal resistivity characteristic reducing smoothly from a high resistance at an isolating boundary layer 61 to a low resistance at the top surface 62. Coupling between successive matrices is effected over a wire formed by metallized deposition or as a diffused resistance element having distributed capacitance and resistance characteristics matching the needs of the diodes.

Title: Machine for lifting beetroots
IPC: A01D17/12
Filed: 1969-12-18
Abstract: A multirow beet harvester senses beets in six parallel rows by means of toothed driven sensing wheels 12 which adjust the height of fixed cutters 10 to cut the beet top just below the growing leaves. Disks 30 prevent. the leaves being wedged between the wheels 12 and allow them to be removed onto a conveyor comprising an endless belt of tines 32, adjusted from the ground by a threaded rod 43. The belt raises the leaves into transverse parallel screw augers 44, 45 which transfer the leaves into the central part of the machine where they are taken up by a first central longitudinal conveyor 60 composed of spaced bars. The conveyor 60 transfers material onto a second conveyor 74 of the same type which discharges the leaves into the rear collecting container 84 which may be emptied automatically by operation of a hydraulic cylinder 88 or a mechanical lever, not shown pivoting the rear part of the container about the lateral axis of a pivot pin. The beets are lifted by vertically adjustable shares 89 and/or pairs of inclined disks (not shown) onto one of a pair of rotating disk conveyors 93 which may be frusto-conically shaped and are composed of rods. The beets are prevented from being spun off the disk conveyors 93 by guide rails (101) Fig. 4C (not shown) as they are carried to either side of the machine where they are picked up by bars on vertical elevators 102 from the top of which they are transferred to a container 114. A rotating spoked wheel (138) Fig. 9 (not shown) may assist the transfer of beets onto the disk (135) and a similar wheel (142) may assist the transfer of beets from the disk (135) to the vertical elevator 102. The beet container 114 may be tilted by a hydraulic ram (115), Fig. 5 (not shown) about a pivot (116) to empty the beets or unloading conveyor chains (119, 120) Figs. 2B, 5 (not shown) may be used. The belts and conveyors may be operated by individual hydraulic motors driven by a master pump (141) Fig. 7 (not shown) or may be operated by conventional chains or grooved belts and gears from an engine drive shaft.
