Title: Lens hood (lens shade) for camera lenses, in particular of video and movie cameras
Inventor: CHROSZIEL ALFRED
IPC: G03B11/04
Filed: 1993-04-19
Abstract: In the case of the proposed lens hood (11), the hood mask (13) is located in a fixed surface, in particular a plane, and has an opening, adjustable essentially in this surface or plane as a function of the focal length (27) used, of the lens hood. The hood mask preferably has in each case two curtains (15, 16) which can be adjusted in pairs in opposite directions and which limit the free opening of the lens hood as a function of the focal length (27) used. The curtains are adjusted by electric motors (M1, M2) by means of a rope-and-roller drive (19 to 26). The motors (M1, M2) are driven by a controller (28) which receives the setting values of the lens for focal length and sharpness as input signals via potentiometer (potential divider) tags. <IMAGE>

Title: Method and arrangement for the NOx and CO reduction at a steam boiler fired with pulverised coal
Inventor: STROEER KURT DIPL ING
IPC: F23C6/04
Filed: 1993-04-16
Abstract: The object of the invention is to inject the secondary air and/or the secondary-air/fuel mixture in the combustion chamber in such a way that simple and effective NOx and CO reduction is guaranteed before entry into the second pass of the steam boiler. This is achieved in that, according to the invention, the secondary air and/or the secondary-air/fuel mixture is introduced as an impulse, passing through the flue-gas flow compression, in an area of a cold gas swirl formed by the pulverised-coal/air mixture injection of the pulverised-coal main burners. To realise this, the feed is arranged in an area of a cold gas swirl formed by the pulverised-coal/air injection and is connected to an impulse generator. <IMAGE>

The metering operation can be interrupted by intermediate closure of the hand valve (7), it being possible for a reliability interrogation to take place subsequently when the metering operation is interrupted. <IMAGE>
Patent DE-4318855-A1 (DE)
Title: Device for determining the cut
Inventor: HAGEMEISTER KLAUS
IPC: E04F21/22
Filed: 1993-06-07
Abstract: For marking the cuts of border pieces in panels, boards, blocks and the like, it has been necessary hitherto to determine the length of the border piece with precise dimensions. If the border runs obliquely with respect to the laying direction of the covering, then at least two distance dimensions are necessary. In order to reduce this outlay in terms of measurements, a device for determining the cut has been invented. Furthermore, the device rules out read-off errors and transfer errors. The length of the border piece is determined by a measuring rail which is guided on a base plate. After the length measurement has been carried out, this results in a cutting template, whereupon the border piece is cut to size.

Title: Multiway valve
Inventor: WILKENDORF HARDY
IPC: F16K11/085
Filed: 1993-06-24
Abstract: The invention relates to a multiway valve, in particular for use for cleaning drinks lines in dispensing and tapping installations. A circular valve body (2) is mounted rotatably in an adapted circular cutout in a valve housing (1). The two parts are conically fitted one in the other in order to ensure a sealing action between the two parts. A through-passage (20) in the plane of rotation of the valve body (2) serves, irrespective of the position of said valve body, either to connect the connections (2, 5) for the incoming and outgoing drinks lines to one another, or else to join the drinks lines, via their connections (2, 5), in each case optionally (2, 9; 5, 9) to a connection (9) for a cleaning fluid, via which connection (9), flushing and cleaning of the drinks lines can then take place. A cleaning body (24) can be introduced in each case through an opening (23) in the valve housing (1), which cleaning body is also driven along through the drinks lines during the cleaning operation by the cleaning-fluid column flowing in via the connection (9). <IMAGE>

Title: Process for the hydrometallurgical reprocessing of used batteries for recovering the raw materials
Inventor: FROEHLICH SIEGMUND DIPL CHEM D
IPC: H01M6/52
Filed: 1993-08-30
Abstract: The invention relates to a process for the hydrometallurgical reprocessing of used batteries for recovering the raw materials, in particular zinc, nickel, cadmium, copper, lithium and manganese, in which the fine powder of the batteries formed by comminution and removal of residue materials is digested by means of an acid or an acid mixture and at least a major part of the constituents of the powder are thereby brought into solution. To reduce the operating costs for the digestion of the powdered old batteries for a subsequent dissolution process and thus simultaneously reduce the investment costs for the hydrometallurgical plant and to additionally reduce the reagent and energy consumption, the battery powder is digested by means of a dilute acid, in particular one which does not dissolve the manganese oxides, or a solution of an acid mixture and the manganese oxides are separated from the solution, e.g. as manganese dioxide. <IMAGE>
Patent DE-4329107-A1 (DE)
Title: Method for using wind energy (wind power) from rotor systems resembling windmills by using the rotational forces and the axial forces
Inventor: GRAUMANN PAUL
IPC: F03D5/00
Filed: 1993-08-30
Abstract: Known rotor systems are designed such that the rotational forces are used, while the axial forces in the wind direction are absorbed by bearings and destroyed. The invention consists in outputting the energy (power), absorbed by the rotor, in axial and rotatory directions to a spiral or spindle in such a way that the pitch (lead) of the spiral or spindle corresponds to the force resulting from the rotational force and axial force. This resultant force can be absorbed by a nut or a wormwheel (round pinion) and led off for further use. It is possible in this way to feed all forces absorbed by the rotor for use. The energy yield is higher than when only the rotational forces can be led off.

Title: Method of controlling cleaning mode of printing machine
Inventor: KURZER THOMAS
IPC: B41F35/06
Filed: 1994-11-29
Abstract: The method involves cyclically pressing a cleaning cloth (4), which passes between two rotatable drums for rinsing and squeezing, onto the surface of a cylinder (2) being cleaned and moving it beyond the cylinder. The transport path of the cloth is detected by a sensor which produces a transport path signal.Before the cleaning mode starts the cloth is rinsed and squeezed and, depending on whether transport signals are received, a ready signal or a non-ready signal is generated. During the cleaning cycle a measure of the transport speed is derived from the transport distance signal and is compared with upper and lower limit values. A cleaning cycle end signal is output when the speed reaches the lower limit and an emergency off signal is generated if it reaches the upper value.

Abstract: Pour obtenir avec un alternateur triphasé de véhicule une alimentation optimale en énergie de l'installation électrique, on accroît le courant d'excitation par rapport au courant d'excitation nominal dans le domaine où l'alternateur tourne à des vitesses peu élevées, on réduit ce courant d'excitation dans le domaine des vitesses moyennes et, pour les vitesses supérieures, on utilise de nouveau un courant d'excitation supérieur au courant d'excitation nominal. En mesurant la température dans le régulateur même et du fait que le régulateur est fixé à une partie particulièrement chaude de l'alternateur, on reconnaît à temps le moment où l'alernateur atteint une température maximum. On réduit alors suffisamment le courant d'excitation pour ne pas dépasser cette température maximum.
