Title: Electroslag welding of metals - includes maintaining weld metal in molten state after welding current is switched off
Inventor: SAFONNIKOV ANATOLY NIKOLAEVICH
IPC: B23K25/00
Filed: 1980-12-17
Abstract: Metals are electroslag welded by forming a flux bath, melting the electrode and the weld edges, filling the gap between the weld edges with molten metal and maintaining the metal in a molten state for a period after the weld current is switched off, the heat capacity of the flux bath being simultaneously raised. The period is pref. 10-15% more than the time required to degasify the weld metal. The heat capacity of the flux bath is raised pref. by increasing its vol. A pref. flux bath contains (in wt.%): BaF2 60.0-90.0, CaF2 5.0-15.0, LiF 1.0-5.0, NaF 1.0-10.0 and KF 1.0-15.0. The process is used for welding non-ferrous metals such as Al, Mg, Ti etc. and their alloys, in partic. Al bus bars and conductors. Welding process is stable and results in a high quality weld seam of low gas content since the rate of electrode melting is self-regulating and the degree of gas removal from the weld metal during and after welding is enhanced by slowing down the rate of crystallisation of the weld metal.

Title: Guidance conductor for driver-less vehicle - controls vehicle to move along track by detection of induction field, and is energised by high frequency current
Inventor: ABE EIJI
IPC: G05D1/02
Filed: 1981-02-26
Abstract: The device includes a continuous conductor layed parallel in a predetermined space relation to each other within a track way so as to form a closed circuit. This is energised by electrically energising the closed circuit so as to allow a high frequency current to flow in the guidance conductor. Moreover, a driver less vehicle employed for being controlled to move along the track way detects the induction field generated by the guidance conductor. As a result, the guidance conductor of this invention may be made possible to lay the whole length on the same track way upon which the driver less vehicle rides. This dispenses with a complicate laying work of the lead wire in the conventional guidance conductor, resulting in a relatively low cost of materials and construction work.

Title: Selective metal extn. from soln. - by controlled pH variation in cathodic zone of diaphragm cell
Inventor: EVDOKIMOV VSEVOLOD BORISOVICH
IPC: C25B9/19
Filed: 1981-09-18
Abstract: Metals are selectively extracted from leach solns. by dividing a d.c. field region into an anodic zone and a cathodic zone through which solns. to be treated are passed simultaneously. The pH of the soln. in the cathodic zone is maintained at a value in the range 1-14 by applying external electric and magnetic fields, the feed rate of the soln. and the rate of pH variation being selected for selective pptn. of (hydr)oxides of different metals at different respective pH values within the pH range. The leach soln. may be passed simultaneously through the cathodic and anodic zones; alternatively, an aq. chloride soln. (e.g. a sylvinite soln.) or an aq. sulphate soln. (e.g. a sodium sulphate soln.) may be passed through the anodic zone instead of the leach soln. The process is useful for selective extraction of non-ferrous metals from natural or synthetic leach solns., chemical etching solns., and waste water and other waters. Addn. of alkali for pptn. of the metals and the provision of activated carbon in the inter electrode space are not required. Metals can be recovered from strong or weak solns. with max. yield and min. energy expenditure.
