Patent DE-3941772-A1 (DE)
Inventor: TOBITANI HIDENORI
IPC: G11B20/10
Filed: 1989-12-18
Abstract: A magnetic disk drive apparatus having a control method which limits data errors created by low frequency interference comprises a magnetic disk having separate data and servo information areas in which an irregular servo pattern is written on the servo surface, rather than the customarily employed regular servo pattern which serves to eliminate the close correspondence of the frequency of the data writing signals and certain internal clock frequencies, and hence the generation of low frequency interference from the interaction of these frequencies. The servo information consists of data written to have intervals between one from the other, intervals between adjacent two data being different from adjacent bit intervals.

Title: Warping tension control - uses brake and speed controls to give constant warp tension throughout winding
Inventor: BABA YOSHIHIRO
IPC: D02H13/14
Filed: 1990-01-29
Abstract: The tension control system, on a warping machine, has a brake assembly (250) to act on the warp yarns within a given range of a brake control input to increase yarn tension, a tension monitor (220) to register the actual warp tension and a memory (211) to store the data to give the nominal warp tension. A comparator (280) matches actual and nominal tensions and gives a brake command (260), if the warp tension is down, to the brake control (240) to convert the brake command value into a go/no go action to cancel the difference between actual and nominal tension values. A warp speed control (290) also has a go/no go action to bring actual and nominal tension values together in conjunction with the brake control assessment.

Title: Dewatering appts. and process for filter cakes -  suspension moves horizontally on filter cloth on filter belt and passes between pressing surfaces with horizontal first dewatering zone
Inventor: PIETZSCH KURT E
IPC: B30B9/24
Filed: 1990-09-04
Abstract: In a process for dewatering suspensions on a filtering belt, a layer of suspension moves horizontally on a filter cloth along an initial dewatering stretch before passing through a press at a second dewatering stage.

Dewatering appts. comprises an endless water permeable belt with a permeable cloth passing horizontally through a first dewatering stage. Both belt and cloth pass between opposing faces of a press which is pref. located within the initial deatering stage. A covering cloth is placed on the filter cake before entry to the press and is removed behind it. USE/ADVANTAGE - The invention is used to dewater suspensions, gives a good dewatering effect at reduced cost and enables belt filters without a press to be modernized.

Title: Monitoring position and dia. of laser beam -  evaluating sound emission signal picked up by sensor if beam deviates to impinge on neighbouring body
Inventor: HAMANN CHRISTOPH DIPL PHYS
IPC: G01J1/42
Filed: 1990-09-05
Abstract: The sound emission signal that is evaluated is picked up by a sensor when the laser beam impinges on a body, e.g. optical holder or shutter. If the shutter is segmented and the segments are acoustically insulated from each other, the directions of the deviation from the stipulated can be ascertained. If the separate segments are set such that no signal is produced, the opportunity arises to enlarge the beam slightly or detected the dia. of a laser beam. The sensor is assigned to a neighbouring part, e.g. a lens or shutter holder concentrically surrounding the stipulated position of the laser spot. USE - Production machines using laser beam, e.g. as flying optic. Detects deviation from optic or shutter caused by heating of components or soiling of delivery window of laser.
