Patent DE-4403840-A1 (DE)
Title: Recovery of sulphuric acid from used sulphuric acid contg. metal sulphate
Inventor: LAILACH GUENTER DIPL CHEM DR
IPC: C01B17/58
Filed: 1994-02-08
Abstract: Recovery of H2SO4 from metal sulphate-contg. used H2SO4 comprises vaporising the used H2SO4 contg. up to 50-75 wt.% H2SO4 concn., opt. cooling the suspension, removing the recovered H2SO4 from the metal sulphates, thermally cracking the metal sulphates at 800-1150  deg C to metal oxides and SO2-contg. cracked gases, cooling the metal oxides and cracked gases in a vaporising kettle to 270-350  deg C, dedusting the cracked gases in an electrostatic gas purifier, adiabatically cooling the dedusted SO2-contg. gases in an quencher, cooling the quenched gases to 25-50  deg C, demisting and drying the cracked gases and processing to H2SO4. The novelty is that quenching of the dedusted cracked gases occurs using metal sulphate-contg. used H2SO4, contg. no solid Fe-sulphate, where the used H2SO4 is injected in to the quencher and a corresponding amt. of used H2SO4 ejected of higher concn., max. 28-32 wt.% H2SO4. The fine dust particles are scrubbed from the cracked gases and the concentrated used H2SO4 is vaporised to a concn. of 50-75 wt.% H2SO4 without removing the suspended fine dust particles

Patent DE-4407934-A1 (DE)
Title: Overcurrent relay
Inventor: SAKO YUJI
IPC: H01H83/22
Filed: 1994-03-09
Abstract: An acceleration mechanism (130c, 29b) in an overcurrent relay is specified, in order to increase the movement speed of operation of a resetting rod (130) or the speed of the movement, caused by the resetting rod (130), in a break contact (18). When the overcurrent relay is used with a resetting mechanism which carries out the resetting by a movement of the resetting rod (130), the overcurrent relay can eliminate a very dangerous abnormal process where, specifically, resetting energy is stored in a toggle-lever mechanism. The safety of the resetting mechanism is thus improved. <IMAGE>

Patent DE-4416559-A1 (DE)
Title: Projectile speed and flight altitude-position determination unit for testing armour plating
Inventor: HELD MANFRED PROF DR
IPC: G03B15/16
Filed: 1994-05-11
Abstract: The line of vision of the camera unit (7) runs vertical to the direction of flight of the projectile. A mirror arrangement (11) is arranged in the vision field of a CCD camera unit (7) with single picture storage, and an illumination source e.g. a flash unit (8). As the projectile interrupts two light beams (1.1,2.1) a counter (3) measures the projectile speed from the time interval and the distance (S1). On interrupting the second light beam, a second counter (6) is started so that the camera and light source are triggered when the projectile passes. The camera unit detects the projectile simultaneously from at least two different directions vertical to the flight path, by means of the mirror arrangement which has a mirror arranged near the flight path in the field of vision of the camera unit, the mirror plane of which is inclined at 45 deg. to the line of vision of the camera unit, which enables the flight path to be seen from above. This results in a split picture, where each half represents horizontal and vertical deviations from the fight path.

Title: Keyhole surgery set=up
Inventor: SCHUBERT WERNER DR MED
IPC: A61M13/00
Filed: 1994-07-01
Abstract: Fibrin etc adhesives are available to prevent gas transferring from the abdominal cavity into the body tissue assisted by artificial peritoneum lesions, and devices and instruments (1-4) are available to guard against interstitial central (and latent) emphysema in the event of tissue splits. The operating surgeon instals variably inflated balloons within the stomach cavity to form a tunnel to the focus or diseased organ, and the induced pressure of the balloons can be reduced at will. Vacuum sones (1,2,3) and associated pumps (P) draw off the air and gas from the stomach cavity, using diffusion for the retroperitoneal space, with resorption assisted by latent emphysema in the trunk. Long-stem injection syringes with short cannula for perhydro are also used to expand the cavity of hollow organs by aseptic oxygen foam, at the same time tightening the walls of the organ and associated blood vessels. The vacuum sondes are in the form of glass, metal or plastics tubes or again in hose form, being flexible and successively perforated in their walls.

Title: Crown cork removing equipment
Inventor: BAECKER HANS-JOCHEN
IPC: B67B7/16
Filed: 1994-09-01
Abstract: The crate is moved under the roller (15) on a conveyor driven by an electric motor.

Title: Steel scrap smelting
Inventor: KOHLER HERBERT DR ING
IPC: C21C5/56
Filed: 1994-11-04
Abstract: Steel scrap is melted in an electric furnace includes using a secondary scrap opening (22) in a side wall of the electric furnace (1') over the level of the molten metal, with a further conveyor belt (14) for the secondary scrap (15) of shredded and uncleaned steel waste which can also contain organic clinging material.

Patent DE-4443732-A1 (DE)
Title: Voltage converter arrangement e.g. for local tramway vehicles
Inventor: ALMEDER ERNST
IPC: H02M7/48
Filed: 1994-12-08
Abstract: A voltage converter produces a three-phase output as well as a separate d.c. voltage output from a direct voltage input. There is an input filter (l1, c1) and a circuit generating a first intermediate voltage using an IGBT transistor pair (t1, t2). There is also a push-pull  inverter stage with IGBT transistors (t3, t4) feeding a transformer primary. The transformer's first secondary winding supplies a first rectifier circuit with diodes (d3 to d6, l4, l5, c4, c5) generating a second intermediate voltage that is symmetrical about the centre tap of the winding. Six controlled IGBT transistors (ta to tf) use this second intermediate voltage to generate a three phase voltage. The second secondary winding (w2s) supplies  a full-wave rectifier (d7, d8) with output filter.
