Title: Method and appliance for the deposition of copper from ammoniacal copper chloride solutions
Inventor: NEUMANN KARL-HEINZ DIPL CHEM
IPC: C23F1/46
Filed: 1987-11-17
Abstract: The invention relates to a method and appliance for the electrolytic deposition of metallic copper from ammoniacal copper chloride solutions. It can be used for extracting copper from etching solutions which arise, in particular, in etching printed-circuit boards, and for the deposition of defined copper layers. The object of the invention are process steps for treating electrolyte solution involving ducted flow of the electrolyte from the bottom upwards in an electrolytic cell, making use of the thermodynamic effect associated with heating during the flow of electric current, enhancement of the buoyancy effect of rising oxygen bubbles, and a hydroxyl ion concentration at the anode surface with a pH equal to or greater than 8.3. The electrolytic cell has electrodes dimensioned so that their width is greater than their height, the anodes being positioned obliquely with respect to the cathodes, and partitions being arranged between cathodes and anodes. The effects include the circulation of the electrolyte solution, the extraction or recovery of electrolytic copper of high purity, high energy utilization and suppression of the formation of chlorine gas and thus the use of ammoniacal copper chloride solutions for the fields of application mentioned. <IMAGE>

Patent DE-3815331-A1 (DE)
Title: Connecting device, in particular for items of furniture
Inventor: BARTH HUBERT DIPL ING
IPC: F16B12/40
Filed: 1988-05-05
Abstract: Items of furniture for special work places are often expensive because they cannot be manufactured by mass production. The invention thus proposes a connecting device, in particular for items of furniture having a frame made up of tubes of any cross-section, which makes it possible to produce the parts for special work places by mass production. Moreover, work places produced by this connecting device can be easily adapted to altered requirements because the connections can be released. Despite the dismantleability, the items of furniture are very stable because the connecting locations can absorb high forces and moments. This is achieved in that there are provided, at the connecting locations of at least two tubes (1, 2), reinforcement elements (3, 4) which are introduced into the tubes and are provided with through-passage bores for receiving a connecting screw (7). <IMAGE>

Title: Fresh fat separator
IPC: C02F1/40
Filed: 1988-06-14
Abstract: The novel process for separating off oils and fats and sink and float materials from waste waters (effluents) which are primarily contaminated with organic constituents is characterised in that the waste water constituents (fats and sink materials) separated off are each gathered on a small cross-sectional area, compressed (concentrated) and removed from the separator housing at short intervals. As a result the aim is achieved of protecting organic waste water constituents against decay in order to lead to an expedient reuse or exploitation. In addition, the thermal energy arising with the waste water is utilised.
