Title: Circuit arrangement for battery buffering of the power supply of electrical hardware modules
Inventor: MAIER WILLI DIPL ING
IPC: G06F1/30
Filed: 1989-03-14
Abstract: In order to buffer the power supply of electrical hardware modules (RAM), especially semiconductor memories, with a main battery (HB1) and a reserve (backup) battery (RB1), a comparator (KMP) is provided which compares the voltage of the main battery (HB1) with a reference voltage (Uref) and, in the event that it is lower, adopts a switching state in which it connects the hardware module to the reserve battery (RB1). This switching state is maintained until the comparator (KMP) is reset by the pulse associated with a replacement of the main battery (HB1). The invention finds application in battery-buffered semiconductor memories. <IMAGE>

Title: Plant for thermal mineralisation of waste residues of low heat value - with passage of flue gas from furnace through residues in kiln
Inventor: VOELSKOW PETER
IPC: B01D53/86
Filed: 1990-01-18
Abstract: A plant for thermal mineralisation of residues of low heat value from waste mixts. after max. utilisation of the organic matter, uses a furnace for any fuel, followed by a heat-sterilisation plant in which residual organic matter in the residues of low heat value is carbonised at low temp. or oxidised. The plant includes a roasting kiln, in which the low-heat residues are spread on the grate, combined with a furnace in such a way that (part of) the flue gases from the furnace are led through the grate and through the residues. Pref. the furnace is a melt-chamber furnace. The flue dust from the flue gas cleaning, the low-temp. coke from the kiln, and granulate absorbing harmful substances from the flue gas post-cleaning are fed into the furnace. Additionally, fractions from rubbish disposal, e.g. flue and filter dust from waste combustion units, combustible liq. waste e.g. chlorofluorocarbon or polychlorinated biphenyl waste, waste oil, or pasty waste, e.g. lacquer sludge, may be fed into the furnace.

Title: Disposal of scrap circuit boards - by dissolving in melt of alkali hydroxide and alkali oxide and adding oxygen to form peroxide(s) for controlled oxidn. of binder
IPC: B09B3/00
Filed: 1990-01-21
Abstract: Process for environmentally friendly breaking down of circuit boards in which the boards are dissolved in a melt of alkali hydroxide and alkali oxide and oxygen is added onto the oxide in the melt to form per-compounds which oxidise the carbon- and hydrogen-contg. cpds. in the boards. Glassy components of the board such as glass fibre react with the melt to form silicates. USE/ADVANTAGE - The process allows disposal of circuit boards without formation of toxic gases as occurs with previous thermal decomposition processes. The binder is decomposed by a controlled oxidn. reaction; glass fibre reinforcement dissolves in the melt to form silicates. Metals originating e.g. from the conductor patterns on the board can be removed from the melt for reprocessing and any unburned carbon remains in the form of carbon black which can be recovered for re-use. The residual melt when cooled yields a waterglass-like material which if left to stand in air forms cabonate which is also useful in industrial applications.
