Title: High corrosion resistance composite plated steel strip and method for making
Inventor: UMINO SIGERU
IPC: C25D3/56
Filed: 1985-06-07
Granted: 1990-04-02
Abstract: The dually plated steel plate has good resistance against corrosion before or after being painted.  In the electrically Zn plated zone there is Co in an amount in a range of 0.1-10 wt.% chromium in a range of 0.05-5 wt.% and Al and Si each in a range of 0.05-5 wt.%, all eutectically deposited.  In this plate, good resistance against corrosion can be obtained not only from the plated zone itself but also from the plate after having been painted.  In addition any paint as well as the plating applied can favourably adhere to the plate. The plate also has good workability.

Title: Apparatus for mixing and casting mortar
Inventor: LEE IL-WON
IPC: E04G21/04
Filed: 1992-07-18
Granted: 1995-08-14
Abstract: The discharger combined with a screw conveyer and a mixer spouts under pressure a viscous mixture of a prepared culture soil and a vegetable binding agent mixed at the work site to from planting mats for afforestation of bare earth banks of rivers and lakes or of newly cut hill sides. The mixer has a tank equipped in center with a rotary shaft having mixing blades and provided at the bottom with an opening closed or open by a sliding plate by a lever for the screw conveyer to receive the soil mixture to convey into the discharger and spout though a nozzle to form a planting mat on the target earth bank.
