Title: Method for indexing measurement values to be processed
Inventor: BERGER BERND DR ING
IPC: G01L5/04
Filed: 1988-09-09
Abstract: The invention relates to a method for indexing measurement values to be processed in a rotating multiple sensor having individual sensors which are distributed at peripheral axially predetermined distances on a rotor. The invention is mainly used in a flatness measuring roller with circulating force transducers. Whilst, in familiar manner, special measures are required for determining the time of measurement value processing when the application sectors of the rotor change, this is avoided according to the invention in that the measurement values are additionally differentiated during one rotation, and in that the continuously sensed measurement values are at least partially subjected to the further processing at the time at which their differentiation exhibits an extreme value. The amount of the extreme value is located between its maximum and its minimum or between its maximum and its zero value. Other sensors and transmitters for extracting the measurement value, must be omitted.

Title: Method and arrangement for determining the magnetic flux of asynchronous machines
Inventor: STIEBLER MANFRED PROF DR ING
IPC: H02P21/14
Filed: 1989-01-07
Abstract: For a method for determining the magnetic flux of asynchronous machines, in which the rotor flux is estimated using a machine model formed by measurement parameters of the asynchronous machine, the intention is to achieve substantially higher accuracy with low expenditure. It is intended to be largely independent of rotational speed and to exhibit little sensitivity to deviations of the modelling parameters from the true values. This object is achieved by using a multi-stage machine model having a first model (1) for the stator and a second model (2) for the rotor, by determining computed values of the state variables of the rotor flux in various ways in both models and by feeding back the difference in the computed values to the first model (1). In a particular embodiment, on the one hand, in the first model (1), the estimated value of the rotor flux <IMAGE> is determined as a linear combination of the stator measurement parameters <IMAGE>  and of an estimated magnitude of the stator flux <IMAGE> from the output of a flux integrator (7) and, on the other hand, in the second model (2), using a computed estimated value of the stator current <IMAGE>  a further estimated rotor flux value <IMAGE> which acts as a pseudoparameter is determined, and the difference between the two flux values <IMAGE>  is fed back to the input of the flux integrator (7). <IMAGE>

Title: Power steering system with infinitely adjustable stops
Inventor: SALG DITMAR
IPC: B62D5/06
Filed: 1989-01-14
Abstract: By means of a well protected and space-saving thread mechanism which is integrated in the pressure tight housing (1) but can be operated axially in front of it within an adjustment range H, this power steering system provides a means of changing the travel paths of its adjustment element piston (4), which means it is easy to manufacture, precise, clearly visible and permits infinitely variable adjustment, simply by turning a tool engagement profile (9) on a bushing (6) which surrounds its actuation rod (3) in the floor (5) of an end wall of the housing (1) and is secured thereby by means of a locking ring (10) in an axially secured fashion, on which bushing (6) a threaded sleeve (13) which bounds the travel of the piston (4) runs. This sleeve (13) is guided in a rotationally fixed but axially movable fashion for example by means of a locking pin (15) which is fixed to the housing and engages in a longitudinal groove (16) on its surface. The outward displacement of the sleeve (13) in the direction of the piston (4) is bounded by end stops which are formed by a collar (14) of the threaded sleeve (13) on one side and by an annular collar (11) of the bushing (6) or in the housing (1), e.g. on a cylinder liner (2) on the other side. In a particular embodiment, it is possible, by means of a damping housing (4A) arranged in front of the piston (4) and by means of a radial hole (19A/B) which leads radially outwards from an annular gap (18) between the bushing (6) and rod (3) when the piston (4) approaches the piston-side end face of the bushing (6) or of the threaded sleeve (13) which, in this process, ... as a result of a ...

Title: Protective shield for dough cutting and working tools - is automatically coupled by crank mechanism to tool drive to prevent operator injury
Inventor: FINDEISEN HANS-JUERGEN DIPL IN
IPC: A21C11/00
Filed: 1989-04-11
Abstract: Cutters and other fashioning tools for dough are held in the top section of a combined assembly whose lower section holds the drive unit and controller, put into operation by a starter button. To ensure an operator's hand cannot be present in the top section, e.g. with the intention of removing an unexpected obstacle, while the tools are operating, a shield moves from a rest position into a protective position, travelling along vertical guide surfaces. This reversible movement derives from a crank drive driven by a motor with a worm drive which automatically cuts out when the crank drive has reached a dead-point after 360 deg. rotation in a position corresp. to the shield in rest position, but resumes when the shield is in protection position. ADVANTAGE - Avoids need for muscular effort in manipulating the shield.

Patent DE-3916115-A1 (DE)
Inventor: KEUTGEN FRANZ DIPL ING
IPC: C23C4/123
Filed: 1989-05-16
Abstract: The invention relates to a method for the production of rotationally symmetric bodies by atomising a metal melt, collecting the resulting metal droplets on a rotating surface, the surface being completely covered with metal droplets after one complete revolution, continuing to move the surface, while maintaining the rotation, out of the collecting position or plane of atomisation. In order to improve known methods in such a way that the body produced has as uniform a diameter as possible over its total length, it is proposed that the position of the plane of atomisation be determined continuously during the feed of metal droplets and the speed of movement of the surface and/or the mass flow of the metal droplets be controlled so that a predetermined ideal position of the plane of atomisation is maintained.

Patent DE-3918905-A1 (DE)
Inventor: NEUHAUS KLAUS
IPC: H01F38/42
Filed: 1989-06-09
Abstract: In practice, the primary winding of a diode-split transformer is usually produced as foil winding in order to ensure good functional capability. In the novel diode-split transformer, the prerequisites for good functional capability of the diode-split transformer should also exist when the primary winding is not produced as a foil winding. Essentially, this is achieved by the fact that the primary winding (3) is constructed as a single-layer cylindrical coil and the end of the primary winding remote from the base (1) of the diode-split transformer is brought back to the base through a recess (6) in the coil former. <IMAGE>
