Patent DE-3844582-A1 (DE)
Title: Launching device for space shuttles
Inventor: BIER FRIEDHELM
IPC: B64F1/04
Filed: 1988-10-15
Abstract: A known drive device for launching space craft operates using magnetic forces. For this purpose, stator rails are fitted along the launch track and reaction rails are provided on the space craft, which, in conjunction with the stator winding, accelerate said space craft. The reaction rails which are fitted to the space craft increase its weight so that the speed which can be achieved using this launching device is inadequate. In addition, the payload of the space craft is reduced. A launching device is proposed in which the reactor rails are arranged in a magnetic track carriage which is guided on the magnetic track path and in the case of which the magnetic track carriage has adjustable folding supports in which the space shuttle is held detachably during launching.
Patent DE-3901807-A1 (DE)
Inventor: SCHNETTLER ROLAND
IPC: C25D7/06
Filed: 1989-01-21
Abstract: In a device for electrolytic deposition of metals on one or both sides of strips, preferably steel strips, which form the cathode, the section (7) of the strip to be coated is guided through a gap between two parallel anodes (3, 4) which are insoluble in the electrolyte (6). A voltage can be applied to the anodes (3, 4) independently of each other. One of the two anodes is subdivided perpendicular to the direction of motion of the strip into several sections (41, 42, 43, 44) electrically insulated from each other, to each of which a different voltage can be applied. Several processes for controlling this anode (4) for one-sided coating of strips in this device are described.

Title: Reverse osmosis purifies part of water supply for drinking - while remaining flow is used for less demanding domestic needs
Inventor: LAUER GUENTER
IPC: B01D61/12
Filed: 1989-05-06
Abstract: A supply of water of less than ideal quality is delivered to a purifier (5) holding one or more semi-permeable membranes (6) which with suitable differential pressure pass through the purifier a supply of pure drinking water. Additives such as flavour enhancing CO2 are electronically controlled.  Water travelling past, but not through, the membranes is used for domestic purposes such as baths, toilet flushing etc. The purified water is delivered to a storage cotnainer, e.g. an expandible flexible bag (18) inside a rigid casing.  If not used in a set period, e.g. 3 days, this stored water is returned to the domestic usage distributor. If the storage cotnainer is full, a counter-pressure is applied near the membrane to halt reverse osmosis and further pure water prodn. USE - Produces pure water, largely free of bacteria, at low cost.

Patent DE-4002206-A1 (DE)
Title: Control to protect catalytic converter during engine malfunction - providing warning on detecting faulty closure of tested valve, and forbidding injection cut-off during engine overrun
Inventor: MAYER RUDI
IPC: F02D41/22
Filed: 1990-01-26
Abstract: A test is (S1,S2) is carried out by a diagnostic process, whether each injection valve of the engine fuel injection system still closes correctly. If this is not the case and the engine is not operating at full load the mixture of fuel and air for all cylinders is enriched and injection cut-off during engine overrun operation is forbidden (S5). This ensures that the quantity of oxygen reaching the converter in all load ranges is limited so that harmful after-burning does not take place in the converter. The converter is thus protected against overheating, but operation of the engine can continue. Mixture enrichment includes suspending mixture regulation on the basis of excess-air factor determination. A warning indication is provided in response to detection of faulty closing of a tested valve.
Patent DE-4002308-A1 (DE)
Inventor: PUESCHMANN MANFRED
IPC: D01H1/00
Filed: 1990-01-26
Abstract: Staple fibre yarn is produced by imparting twist to thread material (2) in two stages by means of a drawing frame, a centrifugal spindle (6) and a spooling unit. During the first stage a fibre strand passes from feed point (1) to spindle (6) to be partly spun. During the second stage the partly spun thread is withdrawn from the spindle which continues to rotate thereby completing the spinning process and the thread is wound up on a spool. At the changeover from first to second stage a roller (4) is moved to clamp the strand against a roller (3), the rollers rotating to withdraw the strand from the spindle. Because the twist no longer runs back to feed point (1) the strand ruptures and the end from the spindle is taken in by a nozzle (10) for subsequent feeding to the spooling means. <IMAGE>

The latter can be hollow, the free ends being joined together by a rib which does not completely occupy the hollow space. USE/ADVANTAGE - The top edge of the skirt, nearest to the crown, can be closer to the gudgeon pin axis.
Patent DE-4010966-A1 (DE)
Inventor: GROTHE HORST
IPC: B22D11/12
Filed: 1990-04-05
Abstract: Hitherto, only one roller carrier, which is connected to the supporting frame, has been used to support the metal strand emerging from the strip casting plant. However, it is a disadvantage here that, if required, the roller carrier can only be adjusted as a whole, i.e. as a complete unit, relative to the strand of cast metal and does not allow any adjustment and/or setting, in particular fine setting, in mutually separate zones relative to the cast strand. According to the invention, in contrast, adjustment and/or setting of the rollers of the roller carrier relative to the cast strand is possible in a simple manner in any desired zone by virtue of the fact that the roller carrier (3) is divided into a plurality of roller-carrying segments (5) which are connected to adjusting devices (6, 7, 8, 9, 10).
