Patent GB-2129243-A (GB)
Title: A circuit for providing a source of pulses for an electronic suppression of pain
Inventor: KYMPL VLADISLAV
IPC: H03K3/282
Filed: 1982-10-05
Abstract: A multivibrator with a rectangular wave output (at A-B) has doubled the amplitude of the feeding voltage (0- +U). The invention comprises a multivibrator with two pairs of complementary transistors. By switching the voltage (at B) at the base of the capacitors 4 and 5 when they are charged, voltage doubling is achieved so the output pulses have double the amplitude of the supply. The invention may be applied for battery instruments, where one needs voltage pulses, the amplitude of which is greater than the value of voltage of the feeding batteries, e.g. a portable embodiment of instruments for an electronic suppression of pains. <IMAGE>

Title: A process for the solidification of aqueous radioactive waste
Inventor: KADNER MARTIN
IPC: G21F9/14
Filed: 1983-09-01
Abstract: For the solidification of aqueous, nitrate-containing radioactive waste solutions by evaporating with phosphoric acid and converting the resulting phosphates into a difficultly soluble solid, a process is required which allows the production of anhydrous final storage products, with a good compatibility with the known embedding agents which can be highly charged with the solid waste. If the alkali metal phosphate residue remaining after evaporation is mixed with alkaline earth metal oxides and/or alkaline earth metal hydroxides, and heated at from 500 to 950 DEG C, alkali metal-alkaline earth metal phosphates of the rhenanite type are obtained which are practically insoluble and may be embedded in known binders in large quantities and with a good compatibility.
