Patent DE-4009495-A1 (DE)
Inventor: DRESCHER GUNTER DIPL ING
IPC: F16F9/05
Filed: 1990-03-24
Abstract: A rolling-lobe air spring has a rolling lobe which is formed from elastomeric material and is provided with embedded strength supporting layers. Both ends of the rolling lobe are in each case fastened to a fitting. Under normal operating conditions, the rolling lobe forms a rolling fold which changes during contraction and expansion. In order to reduce the technical cost during production and assembly of the air spring, and to reduce its weight, one end region of the rolling lobe is constructed as a more greatly reinforced lobe wall section (15) which has stable dimensions with respect to the air spring internal pressure and the external loading by the rolling fold (17). The rolling lobe created in this way rolls off with its rolling fold over the reinforced lobe wall section, that is to say over itself. <IMAGE>

Title: Stable X=ray tungsten filament - uses pre-tensioned helical heater under shielded well in cathode
Inventor: BRETTSCHNEIDER HORST DR
IPC: H01J35/06
Filed: 1990-07-07
Abstract: One problem with stability of emmission in the operation of X Ray tubes lies in the distortion or displacement under thermal stresses in the directly heated cathode-filament. This is overcome by using a tungsten filament (46) wound as a helical spring and held in tension between two pillar-electrodes (44,45) mounted in an insulated base (43) and carrying the filament current. Under typical operating conditions it is sufficient to set the strain in the spring to not less than 10% above its length when cold. Electrons are drawn off by the anode only from the coiled section, the ends and the electrodes are shielded by overhanging plates (48,49) set in the cathode-well (51) above the filament. ADVANTAGE - Heating and ageing effects on cathode geometry are minimised.

Title: Electrolytic regeneration of acidic copper etch solns. - using two-compartment cell sepd. by cation-selective membrane for the generation of chlorine@ for oxidising etching agent and oxygen@
Inventor: DOERRENBACH FRANK DR
IPC: C23F1/46
Filed: 1991-06-07
Abstract: Process for electrolytically regenerating acid copper etch solns. contg. FeCl3 or CuCl2 includes the cathodic deposition of Cu and anodic oxidn. of the etch soln. The electrolysis is carried out in two separate cells. Chlorine is produced in one cell, and oxidises the etching agent. The anode of the other cell is placed in an. aq. sulphuric acid soln. sepd. from the etch soln. by a cation-selective membrane. This results in the formation of gaseous anodic oxygen. The ratio of chloroxidation to oxidn. by oxygen is controlled, leading to a reversal of the changes which have arisen during etching. Also claimed is the device for carrying out the process, comprising an electrolysis cell with cathode and anode compartments sepd. by a diaphragm, with feed and discharge lines for the etch soln. to the two compartments. Metallic Cu from the etch soln. is deposited on the cathode, and chlorine is formed at the anode and reoxidises the etch soln. A further anode is provided, which is immersed in aq. sulphuric acid and is sepd. from the etch soln. by a cation-selective membrane. There are separate control elements for the electrolysis at the two anodes, and further control elements for the feed and discharge of the etch soln. to the cathode and anode compartments. USE/ADVANTAGE - Used in the etching of excess Cu from printed circuit boards, etc. Permits accurate control of the compsn. of etch solns. for recycling. No chemicals have to be added which would be removed from the system due to residues adhering to the etched products or deposited Cu.
