Patent DE-3510387-A1 (DE)
Title: Zone anemometer
IPC: G01P5/26
Filed: 1985-03-22
Abstract: In a novel measurement method for measuring the mean speed of flowing transparent media in which scattering centres for light are entrained without slippage, illuminated and non-illuminated plane zones are generated (e.g. by the projection of a ruled grating) alternately in the flow-containing vessel at right angles to the flow speed on a specific path. These zones of transverse scattering centres are thereby alternately illuminated and non-illuminated. The "lighting-up frequency" is directly proportional to the flow speed. An optoreceiver records the statistically fluctuating mean lighting-up frequency and feeds it via a suitable signal conditioning system, e.g. a lock-in amplifier, to a frequency meter with such a high peak time that the latter displays the mean frequency and thus the mean flow speed. The result of suitable selection of the zones per path is that the numerical value of the frequency displayed corresponds up to a decimal factor to that of the flow speed in the desired unit, e.g. m/s. Ultrasound can be used instead of light.
Patent DE-3519159-A1 (DE)
Title: Water-tube steam generator or water-tube hot-water generator
Inventor: WIESER RUDOLF DR
IPC: F23C10/02
Filed: 1985-05-29
Abstract: The proposal relates to the integration of a circulating fluidised-bed furnace into a water-tube steam generator or water-tube hot-water generator of conventional construction. For this purpose, primary ash precipitation cyclones are arranged either internally in the first downstream flue or externally on the side walls of the combustion chamber. Downstream of the primary ash precipitation cyclones, secondary ash precipitation cyclones are provided on the flame gas side for improved purification of the flame gases. The risk of fouling of convective heating surfaces is greatly reduced thereby. Primary and secondary ash precipitation cyclone also permit a variation of the solids content of the combustion chamber and thereby an output control of the steam or hot-water generator by influencing the heat transfer on the cooling surfaces thereof. In this type of output control, the combustion temperature can be kept constant in an advantageous manner. A type of fuel feed to the combustion chamber is also indicated, which thermally relieves the fluidised bed. Finally, a novel multicyclone is also proposed, which is particularly suitable for use on the subject of the invention. <IMAGE>

Title: Vibrato system for stringed instruments, especially guitars
Inventor: SEEHAWER DIRK
IPC: G10D3/14
Filed: 1985-06-11
Abstract: In order to permit the undamped transmission of vibrations of the strings to the overall structure of the instrument and to permit ease of playing, the tautness of the strings is controlled by an articulation system which can be moved by means of a lever from a stable initial position, which it adopts at basic tuning. The vibrato system permits turning to both upper and lower frequencies. The design ensures that the tautness of the other strings is not affected when the tautness of one or more strings is modified, e.g. by breaking of a string or when the instrument is being tuned.

Title: Roll for hot stock, in particular for transfer and rolling operations in the high-temperature range
Inventor: HOLLAENDER GERD
IPC: B21B27/02
Filed: 1985-08-14
Abstract: Rolls and rollers used at high temperatures are subject to high thermal and mechanical stresses. The life of these rolls and rollers is to a great extent dependent on the choice of high-temperature steels. Nevertheless, their endurance remains unsatisfactory because the contact of the slab with the roll shell leads to thermal stress cracks, i.e. in the end fibre, which is subject to the highest mechanical loading. Since the entire roll is subjected to alternating bending stresses, the cracks deepen and the strength of the roll is considerably reduced. Patent DE 2902825 proposes to place the elements which give the roll its strength under the surface of the roll and to prestress the clamping bolts required by this configuration relative to the roll shell so as to give a flexurally stiff roll body. Under operating conditions, the roll shell expands due to the action of heat and the prestressed clamping bolts are strained. The resulting forces considerably exceed those due to normal mechanical loading. The greatest demands are made on the anchorings of the clamping bolts. The anchorings described in Patent DE 2902825 do not meet these demands. The present invention presents various methods and these guarantee, in particular, high endurance of the clamping bolts but also permit economical production of the anchoring, e.g. reuse ...

Title: Device for bounding the field of play and recording ball strikes directly outside the field of play
Inventor: STUPECKY BOHUMIL DIPL ING
IPC: A63B71/06
Filed: 1985-12-09
Abstract: A device for bounding the field of play and for recording ball strikes directly outside the field of play. In order precisely to bound the field of play and to record unambiguously the point where a ball strikes in the critical region directly outside the field of play line, the previous subjective perception by the umpire (referee) is replaced by a safety strip on the outside of the field of play line, in which safety strip there are fitted elements which carry current longitudinally and go slightly beyond its surface. This safety strip forms an open low-voltage protection circuit which is closed by the impact of a ball on the electrically conductive surface and produces a weak-current pulse which is transmitted in amplified form to an optical and/or acoustic signalling system.
