Title: Tin removal from copper scrap
Inventor: WAINER EUGENE
IPC: C22B1/00
Filed: 1971-08-26
Abstract: Selective and quantitative removal of tin from tin-plated copper scrap comprises charging scrap to a furnace at 900-1500 degrees C and passing anhyd HCl gas to the furnace in a controlled non-oxidising atmosphere. The HCl reacts with all of the tin to forms gaseous tin chloride which is recovered as tin chloride and the copper scrap recovered separately. The HCl may be formed in situ from the insulation on the wire. Pollution of atmosphere with lead chloride and tin chloride is reduced and recovery is easier.

Title: Projectile fuse with projecting telescopic plunger - plunger pushed axially into fuse on impact for initiating detonation
Inventor: RUEDENAUER WERNER
IPC: F42C15/188

Title: Distance and changes measurement method - designed for aircraft moving along landing path by radar
Inventor: JOCHEN PETER DIPL CHEM
IPC: G01S13/08
Filed: 1973-03-29
Abstract: A radiation is emitted from a sender mounted on the object, and reflected back to a receiver for evaluation. Reflectors are mounted on the ground along the path at specified distances from each other. At instants determined by a specified position of the object w.r.t. one of the reflectors, the value of Doppler frequency shift is determined from the received radiation reflected from this particular reflector. Instantaneous value of the Doppler frequency shift is compared with calibration values for the distance at specified speeds. The distance of the object path from the respective reflector is determined, and tendency for deviation of this distance from a nominal value is detected.
