Title: Hydrometallurgical process for the treatment of a raw material which contains oxide and ferrite of zinc, copper and cadmium
IPC: C22B19/00
Filed: 1981-09-29
Abstract: A hydrometallurgical process for the treatment of a raw material which contains oxides and ferrites of zinc, copper and cadmium is disclosed, wherein the raw material is neutral leached by means of a sulfuric-acid-bearing solution to leach the oxides without substantial dissolving of the ferrites, a ferrite-bearing residue is separated, and a sulfuric-acid-bearing or ferrisulfate-bearing solution is mixed with the residue in order to leach the ferrite and to precipitate the iron in the form of jarosite in the presence of alkali or ammonium ions under atmospheric conditions at 80 DEG -105 DEG C., and the solid phase is separated from the solution. The sulfuric-acid-bearing or ferrisulfate-bearing solution is added to the ferrite-bearing residue in such an amount that approximately 50-60% of the ferrite dissolves and its iron is precipitated as jarosite, and the slurry of the solid phase is treated at such elevated pressure and temperature that the zinc of the solid phase is converted to zinc sulfate and the iron to hematite in accordance with the following reaction: (5) 3ZnFe2O4(s)+2A[Fe3(SO4)2(OH)6](s)->3ZnSO4(aq)+A2SO4(aq)+6Fe2O3(s)+6H2O (aq) (A=K, Na, NH4

Title: Elevator system
IPC: B66B3/00
Filed: 1983-12-05
Abstract: A plurality of elevator cars under the supervisory control of a dispatcher processor. A communication processor having a plurality of buffers, a memory shared by both the dispatcher processor and communication processor, and an interface between the communication processor and the elevator cars, cooperatively control the flow of information. Car status information, prepared by the elevator cars, is sent to the dispatcher processor via the interface, buffers and shared memory. Car mode information prepared by the dispatcher is sent to the elevator cars via the shared memory, buffers and interface. A semaphore access arrangement speeds up access to the shared memory, and interrupts control transfer of information between the buffers and interface. In the communication process, the dispatcher processor only loads and unloads the shared memory, and the communication processor loads and unloads both the shared memory and the buffers.

Patent ES-8503775-A1 (ES)
Title: Transaction safety system.
IPC: G07F7/10
Filed: 1984-02-17
Abstract: A portable transaction device (31) having an input keyboard (36) is connected via a telephone line (34) to a data processing centre (35), which processes input data, fed from the transaction device relating to client transactions. The transaction device sends an alarm signal (E) in response to entry of an alarm code by the operator if the operator is having to carry out a false transaction under duress. Renewal of a client's file (46) at the data processing centre is prevented when the alarm signal is received at the centre so that the false crediting of funds to the client's account is prevented. A false funds-received processing text (G) is sent back to the transaction device so that a printer (45) enters details on the client's passbook (37) as though the transaction had been carried out normally. The system therefore allows the operator to indicate that he has made a false entry under duress and the data processing centre can take action to ensure that the falsely-credited funds cannot be withdrawn by the client. On the other hand, because the passbook shows an apparently normal updating of his credit, the client is not alerted to the fact that an alarm has been given. The likelihood of release of the operator unharmed is thereby greatly increased.

Title: Digestor tanks.
IPC: C02F11/04
Filed: 1985-02-12
Abstract: A sewage digester tank includes a gas recirculation system in which a pump removes gas which collects at the top of the tank. The gas is discharged through pipes which pass downwards through the tank and through the sludge layer to discharge the gas downwards. The gas scours the sludge downwards to impinge on the base of the tank and then it returns as bubbles which rise through the sludge towards the top of the tank. - Optionally, the digester tank includes a heat exchanger positioned so that gas bubbles rising from the gas recirculation system agitate the sludge adjacent the heat exchanger. This ensures improved heat exchange.
