Patent DE-4229340-A1 (DE)
Inventor: GASCH ROBERT PROF DR ING
IPC: G01H1/00
Filed: 1992-09-04
Abstract: A method for early detection of a crack in a rotating shaft (1) of a turbogenerator set (unit) of a power station, in which signals representing the bending vibrations of the shaft are received in a manner related to the angle of rotation continuously or in time intervals with the aid of vibration pickups (4, 5) in at least two radial directions which are preferably at right angles to one another. The signals are transmitted to a signal processing system (7, 8) which uses them to determine the harmonic vibration components with single, double and triple rotational frequency, and forms with the aid of vectorial composition of these vibration frequencies vibration patterns of single, double and triple rotational frequency. It is provided in the method that the signal processing system (8) resolves the vibration patterns formed vectorally into a component rotating in the same sense as the rotation of the shaft and a component rotating in the opposite sense from the rotation of the shaft, and that the component rotating in the opposite sense is compared with a corresponding reference variable determined in the new or normal state. <IMAGE>

Title: Emergency braking system for air and ground vehicles with metal casing - houses braking mat controlled electronically and hydraulically across toothed roller with R and L fitted impellers each with two nozzles for forward and reverse travel
Inventor: STRUWE GERD
IPC: B64C25/32

Abstract: With any failure of the braking system or an ineffective reaction on slippery ground surface, due to ice, snow or other conditions, a pushbutton is operated so that an underlay mat is pushed under the vehicle wheels, e.g. by a toothed roller with left and right located impellers or runners. The wheels then run on the underlay mat, and by traction and counter-traction, respectively, from the forward movement and the wheels, the vehicle is brought to a quick and assured standstill by the braking effect of the underlay mat. A rubber mat can be used as the underlay. USE/ADVANTAGE - Simple arrangement and installation to give effective emergency braking of vehicles e.g. military machines and vehicles on carrier aircraft.

Title: Hollow roller used in paper-making machines - has axial drillings as a channel system for heat carrier medium feed and exhaust
Inventor: SCHETTLER ULRICH
IPC: F26B13/18
Filed: 1993-05-28
Abstract: The hollow roller has axially parallel drillings which form a channel system for the feed and exhaust of a heat carrier medium in a succession of paths. A displacement body, fixed radially and axially at each end side of the roller, acts with the feed and exhaust channel on one side and the axial ring gap to the inner wall of the roller body on the other side, to form a channel system for a coolant. Each channel system has the same structure for a heat carrier medium and a coolant. The feed and take-off for the heat carrier medium and the coolant are each connected separately at the diametrical flange journals or at the same flange journal. The coolant flows through a drilling system at the journals to cool the roller bearings. USE/ADVANTAGE - The hollow roller is used esp. as a polishing or calender roller or drying cylinder in a paper-making machine. The roller structure ensures a consistent temp. over the roller, including the roller edge zones.

IPC: B65D90/30
Filed: 1993-08-11
Abstract: A retention system for collecting material from a plant is described.   This system comprises at least one drainage line which opens out into at least one flexible container, is connected thereto in a substantially pressure-tight manner, is fitted with a pressure relief safeguard, and serves to relieve pressure and drain material from the plant. In this case, the flexible container must be dimensioned at least to ensure that it has such an internal volume in the filled state that the internal pressure of the connected system consisting of the drainage line and the flexible container virtually corresponds to the external pressure. Furthermore, a method for preventing the escape of material from a plant into the surroundings is described. This method comprises the steps:   a) draining the material from the plant by means of at least one drainage line which serves to relieve pressure and drain material from the plant, b) feeding the material into at least one flexible container which is connected to the drainage line, the flexible container being selected such that it has at least such an internal volume in the filled state that the internal pressure of the connected system consisting of the drainage line and the flexible container virtually corresponds to the external pressure and c) intermediate storage of the material in said flexible container until it can be disposed of in the proper manner.

Patent DE-4336085-A1 (DE)
Inventor: KAUPER RUDOLF
IPC: F26B21/00
Filed: 1993-10-22
Abstract: Processes for the removal of fluid adhering to surfaces of objects to be treated by means of compressed-air jets emerging from orifices in air-jet devices and directed onto the objects to be treated are known. Processes of this type are used, for example, for removing electroplating fluid adhering to surfaces. The disadvantage of the known processes is that stainless drying is impossible or is possible only at a considerable outlay in terms of apparatus. A process and an arrangement, in which, for stainless drying, air-jet devices, from which the compressed-air jets emerge, are set in oscillating movement in at least one plane, are therefore described. As a result, the fluid on the surface of the object to be treated is essentially atomised and consequently removed rapidly from this. The remaining surface moisture can evaporate. Heated compressed air is used to assist the evaporation. <IMAGE>
