Abstract: PCT No. PCT/EP93/00747 Sec. 371 Date Sep. 26, 1994 Sec. 102(e) Date Sep. 26, 1994 PCT Filed Mar. 26, 1993 PCT Pub. No. WO93/19213 PCT Pub. Date Sep. 30, 1993The foundry dust is fed to a first furnace atmosphere which is preferably at 1000 DEG  to 1100 DEG  C. With the dust pellet being continuously rolled around, it remains therein until in particular chlorine, alkali and lead compounds have almost completely evaporated out of the dust. Experience has shown this takes an hour. In that operation a scavenging gas flow is fed to the furnace atmosphere whereby the lead-chlorine-alkali vapour produced in the rotary cylindrical furnace is passed out of sane to a condensation and filtering apparatus. Reducing agent, in particular coal, is then introduced into the foundry dust and same is fed to a further furnace atmosphere which in particular is at 1150 DEG  to 1350 DEG  C., where it is continuously rolled around. In that way the zinc oxide contained in the dust is reduced, the dust remaining in the furnace until zinc has substantially completely evaporated in the form of zinc metal vapour out of the dust into the oxygen-bearing furnace atmosphere and there the zinc metal has changed to zinc oxide. Experience has shown this takes up to two hours. In that operation once again a scavenging gas flow is fed to the furnace atmosphere, to carry the zinc oxide out of the furnace, where the scavenging gas is cooled with the zinc oxide and filtered.

Abstract: A scallop hanger setting apparatus according to the present invention contains a transport mechanism for transporting a pair of horizontally seated scallops, a perforating mechanism for perforating transported scallops' side-flanges and a culturing rope for through-holes, a threading mechanism for inserting a hanging wire member into the through-holes in the scallops and the culturing rope,  a cutter mechanism for cutting the wire member to a predetermined length,  a pressing mechanism for pressing  both  end  portions  of  the  cut  wire member  into deformation, and a driving mechanism for driving each of these mechanisms.  The transport mechanism contains press levers for pressing scallops, and the press levers contain adjusting devices for adjusting press lever pressure imposed on scallops.   The drill guide of a drill in the perforating mechanism is operative so that it detaches from the scallop's side-flange after the threading mechanism completes the insertion of the wire member into the through-holes.  The axis of a guide hole disposed in the lid of the cutter mechanism is offset from the axis of the drill of the perforating mechanism.  Disposed in the cutter mechanism is a water feeder mechanism that feeds seawater at least during the operation of the drill of the perforating mechanism.  A pair of scallops are arranged with one on the left-hand side and the other on the right-hand side of the rope, and one above and the other below the rope horizontally, and the hanging wire member connects two scallops's side-flanges and the culturing rope therebetween.

Title: Dual mode transmission system with switched linear amplifier
Inventor: HEINONEN JARMO
IPC: H04B7/005
Filed: 1995-02-15
Abstract: A dual mode transmitter circuit is disclosed including a non-linear high-power amplifier having an amplification that can be adjusted and a linear high-power amplifier.  A first switch and a second switch are connected to the input and  output of the  linear,  high-power amplifier.   An amplification-adjustable,   high-frequency   transmitter control amplifier is connected to the input of the non-linear  high-power  amplifier.     Means  for  measuring transmission  power  such  as  a  directional  coupler  is connected to the second switch, and a duplex filter is connected to the directional coupler.   A power level control circuit is responsive to the measured transmission power from the directional coupler and to a power level signal.  The power level signal is representative of the desired output power of the transmitter.  The power level control circuit compares the measured power level from the directional  coupler with the desired power level  and produces a difference signal on its output lead which is connected to both the non-linear high-power amplifier and to the high-frequency transmitter control amplifier.   A mode selection signal, for designating either an analog or digital type transmission mode is applied to a mode control circuit that is responsive to the mode selection signal and provides switching signals to the first and second switches and a control signal to the linear amplifier.  The mode selection signal sets the transmitter to function in either the non-linear transmission (analog) mode or the linear transmission (digital) mode.
