Title: Process for regenerating spent chromic acid solutions
Inventor: FUHRMANN AXEL DR RER NAT
IPC: C23F1/46
Filed: 1993-05-10
Abstract: The present invention relates to a process for regenerating chromic acid solutions which have been used in etching, anodising, chromating, roughening of plastic surfaces, oxidising organic chemicals and the like, but particularly for chromium plating. According to the invention, an electrolysis cell having a chromic acid-resistant cation-exchange membrane and an acid catholyte is connected in parallel with a cation exchanger, the catholyte circulates pseudo-continually from the cathode space of the electrolysis cell to the cation exchanger and back. The exchange resin removes all metal ions so effectively that their activity is no longer sufficient for any appreciable deposition on the cathodes. The cathodes remain clean and do not have to be lifted out of the electrolysis bath and have the deposits chipped off. The worked up electrolyte is reusable for a long time. The increase in the operating life enables materials to be used which have hitherto been excluded for cost reasons. <IMAGE>

Title: Method for the production of longitudinally watertight (waterproof) cables
Inventor: KLEBL WOLFRAM
IPC: H01B13/32
Filed: 1993-05-26
Abstract: A method is specified for the production of longitudinally watertight cables, around whose cores, which contain transmission elements, a sheath is formed. Cavities which are present in the core and between the core and the sheath are filled with viscous sealing material which is pumped out of a reservoir by means of a feed pump driven by an electric motor whose rotation speed is regulated, and is fed to a pressure chamber. The pressure in the pressure chamber, through which the core is drawn, is measured continuously and is kept constant by means of a regulator. Sealing material which emerges from the pressure chamber is passed into a receiving container which is equipped with a level switch. It is fed back from this receiving container into the pressure chamber by means of a return pump which is switched on and off by the level switch and is driven by an electric motor whose rotation speed is regulated. The rotation speed of the electric motor which drives the return pump is likewise regulated by the regulator, in the same way as that of the electric motor of the feed pump.

Title: Circuit arrangement for inputting alphabetic characters at a telephone set
Inventor: FREESE JENS
IPC: H04M1/2748
Filed: 1993-07-07
Abstract: In a telephone set, a first memory (SP1) is provided which has a memory location for each letter of the alphabet. The memory (SP1) is cyclically activated by a counter (Z) controlled by a first clock generator (TG1). During this process, the letter information contained in the individual storage locations reaches the display device where it is successively displayed. As soon as a selection key (T1) is operated, the first clock generator (TG1) is switched off and, instead, a second slower clock generator (TG2) is connected to the counter (Z). As soon as the selection key (T1) is released, the selected letter is stored in a second memory (SP2) in such a manner that the individual letters result in a desired word. This circuit arrangement makes it possible to input the necessary information for "telephone book" into the control device of a telephone set in the simplest manner without additional keys.

Title: Bicycle stand module
Inventor: HAMMERSCHMIDT HARTWIG DIPL ING
IPC: B62H3/04
Filed: 1994-03-03
Abstract: Good bicycle parking units should have the following features: they should be simple to use, hold the bicycles in a stable manner, allow the connection of the bicycle frame, rule out damage to the bicycles, utilise space well and have an attractive design. Unlike previously available models the new stand satisfies all of the requirements simultaneously. The front tyre of a parked front wheel is held in a stable manner over more than 50% of its circumference in narrow horizontal and vertical slots (31a, 1a or 31b, 1b). An essential feature is an angle of approximately 10-20 DEG  between the main direction of the supporting stirrup (2) and the horizontal slots (31a and 31b). As a result, no part of the bicycle, apart from the front tyre, comes into contact with the stand during insertion and when parked. An integral part is the possibility of connecting the bicycle frame by looping a short cable lock or U-lock around the upper vertical portions (22a or 22b) of the stirrup (2) and the bicycle steering head. By virtue of various embodiments of the basic module stable, theft-proof, space-saving, attractive and convenient parking units for bicycles can be assembled. <IMAGE>
