Abstract: An apparatus for growing beansprouts, comprising a plurality of containers (1, 2) for growing the sprouts therein mounted vertically one above the other extended above one end of a water tank (4) whereby the containers comprise movable plates (9, 10) to stabilize the seed bed, and movable bases (5, 6, 7, 8) at the bottom of each container, enabling its movable base to move from a position of closing the bottom to a position of opening the bottom, thereby allowing sprouts grown within the container to fall into the tank: where the tank having a means to convey the sprouts received from the containers end of the tank to the other end of the tank.

Abstract: Described is a method for minimizing switching noise in the high- and mid-frequency range on printed circuit cards or boards by means of a plurality of surface mounted decoupling capacitors. A novel configuration and implementation of capacitor pads including the connecting vias is also presented. As a result the parasitic inductance of the pads and vias can be significantly reduced. Thus the effectiveness of the decoupling capacitors in the mid and high frequency range can be increased, the voltage drop can be reduced and the system performance can be increased. Several design rules for the new pad via configuration lead to the significant reduction of the parasitic inductance. The proposal is especially important for high integrated system designs on boards and cards combined with increased cycle times.

Abstract: An improved return path for electric current through a conductive hearth of a direct current arc furnace is provided by pressing a ring of water cooled copper blocks into the periphery of a sidewall of the hearth of the furnace, the hearth having zones of conductive refractory providing an electrical path between the contents of the furnace of the copper blocks. The hearth is compressed by a tensioned peripheral band which may also support the blocks. The peripheral water cooled copper blocks may be divided into multiple groups, each group connected to one pole of a direct current power supply, the opposite pole of which is connected to a suspended electrode, permitting control of arc deflection.
