Patent DE-4217830-A1 (DE)
Inventor: GUENTER STEPHAN
IPC: G06F11/14
Filed: 1992-05-29
Abstract: A method for operating a data processing facility (10) is described in which the data processing facility (10) processes at least one critical program section which initiates the writing of information into a first non-volatile memory (X) and which is left after completed processing, in which arrangement, in the event of the return of voltage following a voltage drop, the information existing in the memory (X) before the voltage failure is provided again. In addition to the first memory (X), a non-volatile second memory (Y) is provided for storing the information and a non-volatile third memory used as status memory (Z) is provided. At the beginning of the writing of the information into the first memory (X), a status flag is written into the status memory (Z) and the information is written into the second memory (Y). When the voltage returns, the information is read out of memory (X) or (Y) depending on the status flag read.

Title: Right- and left-handed capodastro construction kit - for (un)fretted stringed instrument esp. guitar, has curved spindle held on underside of baseplate accommodating slide with roller spindle
Inventor: LIEBCHEN LARS GUNNAR
IPC: G10D3/04
Filed: 1992-07-22
Abstract: The kit comprises different, interchangeable string- and neck-pressure devices (15, 16) such as rollers. On one side is an oblong hollow connecting baseplate (1) alongside the neck aligning the top and bottom neck rollers. A longer spindle (7) curved towards the roller is held by a screwed stud (9) bearing against a flat on it on the underside of the baseplate so that it cannot turn. A round or polygonal sliding bar (3) is secured centrally in the oblong chamber, open to the top, in the baseplate, and accommodates a slide, on which is the spindle for the top spring roller. This is interchangeable, and clamped by a screwed stud. The slide travels along the surfaces of the baseplate chamber. The baseplate has a further slot on both sides for the upwards-bent spindle, which is movable at right angles to the instrument lengthwise axis. Radiused portions are milled out of the baseplate at the top and bottom, for engagement by rubber bands. The tension exerted by the latter acts against the radiused top surface of the slide, pressing both neck and strings downwards. ADVANTAGE - Occupies position forming neck extension when not in use, and is moved into a set position in fractions of a second when required.

Title: Dentures etc. which release fluoride - are produced by e.g injection moulding mixt. of suitable fluoride type cpd. with temp. resistant solvent and convenient polymer
Inventor: BERGERSEN EARL O
IPC: A61C13/20
Filed: 1992-08-04
Abstract: A denture or similar is moulded as follows: a fluoride material is mixed with a high temp. solvent which resists temps. up to 260 deg.C; a measured quantity of a base material is blended into the mix to form a prefluorided material in which the fluoride is uniformly distributed; this last mix is then fused into a melt using a temp. below the high temp. limit set by the solvent, to soften the added basic material and plasticate it to mould it into a prod. which can be fitted into the human mouth. A preferred basic material concerned contains silicone resin, polyurethane, PVC, rubber latex, water blush PVC, polypropylene or polyethylene. ADVANTAGE - The procedure avoids the formation of pockets of concentrated fluoride which would produce hydrofluoric acid when mixed with saliva. It also eliminates any problems of residual fluoride powder in the extruder screw which would again produce hydrofluoric acid if mixed with moisture. It eliminates the formation of spots of discolouration of the denture etc. It prevents thumb sucking and can also cover dummies.

Title: Vapour-current cyclone condensor
Inventor: FAY JOHN M
IPC: F26B5/06
Filed: 1993-07-01
Abstract: A condensor for removing vapour from freeze driers and other containers is described which contains a three-stage vapour distributor in the form of a cyclone or turbine which is mounted to rotate about the axis of an elongated horizontal discharge pipe (output pipe, delivery pipe) which extends through the axial centre point of the condensor chamber. The discharge pipe holds the end and radial spray nozzles which are selectively spraying a cleaning fluid and sterilising vapour onto the inner surfaces of all the components inside the condensor chamber. The condensor includes a multiplicity of condensor parts which are arranged in a radially offset configuration about the discharge pipe in an optically tight configuration which has the effect that vapours impinge on the cold surfaces of the condensor parts before they touch the inner surface of the enclosing condensor chamber. An optical density is achieved by providing the condensor part as metal sheets which are constructed with a serpentine-shaped through-duct between them in order to circulate the coolant. As an alternative, the optical density can be achieved by providing a condensor part which is designed as a metal pipe construction which is bent into a serpentine configuration, open spaces being present between the bent sections, the arrangement of the tubular condensor parts being enclosed by a cylindrical wall, ...

Title: Electricity generators having an integrated internal combustion engine drive system
Inventor: FRITZSCHE KURT
IPC: B60L50/10
Filed: 1993-09-23
Abstract: Electricity generation in the areas of 220V AC and 380V three-phase, by the combination of an internal combustion engine which has very low fuel consumption and drives two generators (petrol or diesel). Two generators are mounted parallel, the drive motor is centred and installed on the generators flush with pulley wheels and the engine drive wheel. The drive engine has a fuel consumption of 3.0 litres per hour and drives the generators via a V-belt having a load capacity of 80 m/s. A power of, for example (depending on the design), 12 kVA/45 A (16 PS) is produced by the two generators at a rotation speed of 3600 min<-1>. The generators are in this case connected in series in the power range. This is sufficient to operate a squirrel cage motor as a drive motor.   The power capability of the generators and of the drive motor is variable, that is to say can be varied for matching purposes. The heavy accumulators for driving an electric car are obviated. The tank remains and thus has an hourly fuel consumption of 3 litres at a speed of 90 km/h, with a radius of 1800 km. The costs are even more favourable using a diesel drive engine.

Title: Process maintains smoke gases at or above dew point after combustion of fossil fuels
Inventor: VOGES WINFRIED
IPC: B01D51/10
Filed: 1994-03-02
Abstract: Hot crude gas charged with pollutants is cooled by apparatus including a crude-gas cooler (3) in the path of flow of the crude-gas stream (1) between an electrostatic filter (2) and a gas scrubber (6) for withdrawing sulphur from the crude gas. A pure-gas heater (8) is incorporated in the pure-gas stream (7) between the scrubber (6) and a chimney (9). The crude-gas cooler (3) and the pure-gas heater (8) are coupled via a cooling fluid conveyed in a closed circuit (11). The heat-transmitting surfaces in the crude-gas cooler (3) are so dimensioned, in relation to the quantity and speed of the crude gas, that in each region of the crude-gas cooler (3) the crude gas conveyed in indirect counter-current to the cooling fluid has a temperature at or above the saturation curve defined by the specific dew-point temperature in the SO 3 /{C temperature graph. By this means, the formation of sulphuric acid aerosols can be prevented, or any sulphuric-acid aerosols formed can be separated from the crude gas.

Title: Improvements to a hydraulic three-chamber system separator BA (WITPU 135, SVGW)
Inventor: DESCH KURT MICHAEL DIPL ING
IPC: E03C1/10
Filed: 1994-03-17
Abstract: The object, in a hydraulic system separator, of avoiding generating in the non-return device of the latter located on the admission-pressure side a permanently predetermined pressure loss of approximately 0.5 bar or even, in the case of reliable design, somewhat above this which stems from the downstream appliance or the consumer, is achieved, according to the invention, in that, as proposed in DE 4,129,352 A1, the backflow prevention on the admission-pressure side is formed by two piston surfaces or diaphragms F1 and F2, F1 = admission pressure P1, F2 = discharge pressure P22, downstream of the non-return device located on the discharge-pressure side and downstream of the appliance to be protected. In principle, the abovementioned surfaces F1 and F2 correspond to the front and rear (D<2>ball. pi ) DIVIDED 4 side of a non-return ball. The sides located opposite the surfaces F1/P1 and F2/P22 are each loaded with atmosphere. Thus, the pressure difference (pressure loss) present in any case in an appliance downstream of the system separator BA and upstream of the actual consumer, such appliances being, for example, an injector (water-jet pump) or a water-treatment apparatus (regeneration with acids and alkalis), is to be used for the system separator, in such a way that the pretensioning of the spring of the backflow prevention located on the admission-pressure side does not entail any additional pressure loss in the BA appliance, as is the case in a hydraulically non-balanced adjusting piston of a mechanical GB appliance, here, since, as described above, instead of P1, [lacuna] Original abstract incomplete. <IMAGE>
