Title: A mechanical current converter
IPC: H02H7/10
Filed: 1958-03-04
Abstract: 865,678. Converting. LICENTIA PATENTVERWALTUNGS-G.m.b.H. March 4, 1958 [March 4, 1957], No. 6899/58. Class 38 (2). In a mechanical current converter in which semi-conductor rectifier elements 4, 5, 6, shunt contacts l, 2, 3 to relieve them of current at opening and closing, the elements are protected by series fuses or switches 7, 8, 9 which respond to excess current at a disturbance or on incorrect commutation, and each fuse has connected across it the primary winding of a transformer 10, 11, 12 so that the voltage appearing across a blown fuse is applied to a trip coil 19 of a protective device for the mechanical converter. This arrangement ensures that if a fuse blows arcing, which might otherwise occur at the contacts at the next cycle due to the absence of the shunt path, is avoided. The protective device of the mechanical converter may be a short-circuiting device or a high-speed circuit breaker. The arrangement includes transformers 20, 21, 22, which compensate for the voltage drop in the elements 4, 5, 6 and ensure that the current is balanced to zero shortly before the contacts open. Commutating reactors 23, 24, 25 are included. The transformers 10, 11, 12 may have series resistors or fuses as protection against saturation.

Title: Improvements in and relating to the production of thin layers of organic liquids in evaporators
IPC: B01D1/22
Filed: 1960-03-01
Abstract: The production of thin layers of organic liquids on the evaporating surfaces of thinlayer evaporators is facilitated by exposing the surfaces to an electric gas discharge.  Preferably the surfaces are exposed to the discharge before contact with the liquid to be evaporated, but whether applied before or during evaporation the gas discharge may be effected in the vapour of the liquid, e.g. as a glow discharge at reduced pressure, the evaporator surface serving as one of the gas discharge electrodes. Alternatively, a high voltage electrode may be insulated and passed through the evaporator wall, or the electrode may be arranged opposite the evaporator surface. Evaporators, illustrated diagramatically, to which the invention is applied are of the type in which liquid to be evaporated is fed as a jet or thrown by a rotor on to a stationary evaporator surface, or fed as a jet on to a rotating evaporator surface, or fed to an endless circulating belt which serves as the evaporator surface. Reference is also made to disc- or drum-shaped evaporators which revolve about a horizontal axis and dip into the liquid to be evaporated.
