Title: Prodn. of coinage steel - using a ferritic stainless chromium steel or special surface hardness and smoothness
Inventor: CHALK DAVID L
IPC: C21D8/02
Filed: 1976-11-26
Abstract: Steel for coinage is a cold-rolled, low-carbon, ferritic, stainless steel contg. C =0.03, Mn =0.50, P =0.04, S =0.02, Si =1.0, Cr 12-18, Ni =0.50 and Al 0.1-0.3 wt.%. The steel is not heat-treatable owing to its low C level. Ingots are hot rolled and box-annealed at 815-845 degrees C for >=1 hr. After annealing a surface layer of up to 0.07 mm is removed and the strip cold rolled, pref. in a Sendzimir mill, to 1.27-1.52 mm. The strip is then annealed in a continuous furnace in a H atmos. at 845-900 degrees C followed by pickling in an aq. soln. of 4-10 wt.% HNO3 and 1-2 wt.% HF. The surface hardness should not exceed Rockwell 8 of 75 and the surface should have a max. roughness of 4.06 x 10-4 mm in order to facilitate stamping and coining as well as to produce a coin with a lustre appearance and showing fine details and contours of the images. The actual metal value of the coin is less than its nominal value so that there is no risk that the coins will be used for purposes other than coinage.

Patent DE-2700145-A1 (DE)
Inventor: LAUERER FRIEDRICH DIPL ING
IPC: H02H3/347
Filed: 1977-01-04
Abstract: If a residual current device uses the neutral conductor as the protective-earth conductor, then, in the event of an interruption in the neutral conductor or interchanging of the neutral and live conductors upstream of the residual current device, the full mains voltage is transmitted to all the connected housings (M) of the load appliances without the residual current device switching off. In order to overcome this defect, in each case one voltage-dependent resistor (1 + 2) is connected between the neutral conductor (12), which is used as the protective-earth conductor, and at least two live conductors (14 + 15) such that, in the event of one of the said faults occurring, the residual current device does switch off. This makes it possible to use the neutral conductor as a residual-current protective earth conductor without any risk, for power stations and electrical fitters. <IMAGE>
