Patent DE-4309551-A1 (DE)
Inventor: SCHIERLING BERNHARD DIPL ING
IPC: F16F15/16
Filed: 1993-03-24
Abstract: A two-part flywheel for a vehicle internal combustion engine has a primary mass (2) secured to the engine crankshaft (4) and a secondary mass (3) mounted on the primary mass (2) with a torsion spring device (10) between them. A clutch pressure plate (12) is attached to the secondary mass (3) and a driven clutch plate (16) interposed between the pressure plate and the secondary mass. In order to simplify automated assembly of the pressure plate (12) on the flywheel, a locking means (21) is provided to prevent relative rotation of the masses (2, 3) during assembly, the locking means being released subsequently to allow rotation. The locking means may be released automatically by attachment of the pressure plate (12). <IMAGE>

Title: Switch for switching on the hazard warning light system for motor vehicles
Inventor: MONTNACHER RUDOLF
IPC: H01H35/14
Filed: 1993-04-06
Abstract: The switch switches the hazard warning light of a car on automatically in the event of an accident or impact of said car. On shock or impact on a car, the ball (9) enables a path from the bolt (7) (which is subject to the battery current), with the ball seat (8) to the entire hazard warning light system, circumventing the manual switch which is routinely provided, and switches the hazard warning light system on immediately. <IMAGE>
Patent DE-4321192-A1 (DE)
Title: Apparatus for distilling water in the low-temperature range
Inventor: GRAEF WALTER
IPC: F24S20/20
Filed: 1993-06-25
Abstract: The apparatus can be used for the desalination of seawater for agricultural purposes. Known "high-tech" distillation processes require primary energy of 30 litres of oil for distilling water. During the day, solar energy is employed. Waste heat from power stations, geothermal energy etc. can be combined. Since only atmospheric pressure and a temperature below 95 DEG C in the interior are employed, and to avoid lime encrustation and corrosion, the apparatus is made of polypropylene. The natural utilisation of gravity, the difference in level from the tank to the heat store, is sufficient for distillation. Solar collectors which comprise glass covering, frame and an absorber are combined with evaporators and heat exchangers to form a wall which is oriented north-south. In addition, mirror foils are irradiated, the angles of which are set by rigging known from sailing ships. The irradiated side is on the east in the morning and is changed at midday to the west. Thermal energy is collected in an energy storage device via a thermosyphon system. Hot water flows to trickle over a sponge, which is only water-permeable at a slight superatmospheric pressure, in Z-shaped flow mats. The droplets forming increase the surface area of evaporation. <IMAGE>

Title: Arrangement having an oblique transformer
Inventor: JAEGER JOHANN DIPL ING
IPC: H02J3/18
Filed: 1993-07-12
Abstract: In the case of a power supply (power system, network) arrangement having an oblique transformer (9), in order to make it possible to improve the control capability for the power flow between the electrical power supplies (1a, 1b) to be coupled, it is proposed to feed the oblique transformer (9) via a converter arrangement (7) with a direct link, in particular a DC link (17). An invertor (15) is preferably self-commutated and angularly controlled, four-quadrant operation being possible. The arrangement advantageously attenuates hunting between the power supplies (1a, 1b). <IMAGE>

Title: Circuit for monitoring voltage lines and at least one clock line of an integrated digital circuit
Inventor: POPPE MARTIN DIPL PHYS DR
IPC: G06F11/00
Filed: 1993-10-08
Abstract: A circuit is proposed which tests the operational state of voltage lines and at least one clock line of an integrated digital circuit. The circuit comprises a T-flipflop with two voltage inputs, clock inputs, a data input and an inverted data output. The voltage lines to be tested are fed to the voltage inputs of the T-flipflop. The clock line to be tested is fed back to the clock input of the T-flipflop. If the voltage lines and the clock line and the clock generator are functional, the data output of the T-flipflop outputs an oscillating signal. If one voltage line or the clock line is defective, the data output of the T-flipflop outputs a constant signal which is detected by an evaluation circuit. <IMAGE>

Title: Twin electrical coils wound around water pipe conduct alternating and direct electrical currents
Inventor: UEING MICHAEL
IPC: C02F1/48
Filed: 1994-09-22
Abstract: In a water treatment assembly to protect supplies from calcium deposits, water passes through a pipe around which are two separate coil windings arranged in sequence and which are both connected to an electronic circuit and power supply. The novelty is that each winding (4,5) is a coil whose two ends are each connected to an electrical direct current supply which overlays an alternating electrical current supply. In the direction of water flow through the pipe (1), the rear coil (5) has a higher direct current and a lower alternating current in comparison with the front coil (4). Almost the full electrical current applied passes through the rear (5) coil. The electrical and magnetic fields generated in the coils are opposite and opposed. The current has a steplike rise and a stepless fall profile in the rear coil (5).

Title: Zinc corrosion element for the production of hydrogen from an alkaline solution at a predetermined rate of gas formation
Inventor: WINSEL AUGUST
IPC: B22F1/17
Filed: 1987-06-05
Abstract: The surface of sufficiently pure non-amalgamated zinc powder is contaminated with 0.1 to 10 atoms % of metallic nickel and pressed into tablets after addition of a thermoplastic compacting agents. To initiate the evolution of hydrogen, the tablets are immersed in an alkaline hydroxide solution to which small quantities of sodium potassium tartrate may be added, if necessary. The process may be carried out either by mixing the zinc powder with a solution of a salt of a noble metal to bring about the precipitation of a foreign metal on its surface, or by coating the surface of the zinc with a decomposable metallic salt of a noble metal which deposits metallic atoms on the surface during thermal decomposition, or by intimately mixing the powder with a noble metal, adding a thermoplastic binder, and pressing it into tablets.
