Title: Induction motor control method - determining stator voltages and switching-in durations for DC-AC regulator supplying motor
Inventor: SEGERER HOLGER DIPL ING
IPC: H02M7/5387
Filed: 1990-10-15
Abstract: The control circuit (2) is coupled to a DC/AC current regulator (6) supplying the induction motor (8) and uses calculated time discrete values for a number of different motor parameters to obtain a prognostic estimation of one parameter. This is used with the detected angle between this and a second parameter, to provide a required value for the latter, in turn used to obtain a control value for the DC/AC current regulator (6). The switching in durations for the stator winding voltages are determined from the mean motor torque, the switching sequence defined by a given pulse pattern. ADVANTAGE - Accurate electrical torque regulation.
Patent DE-4034288-A1 (DE)
Inventor: MUELLER MANFRED
IPC: A44C27/00
Filed: 1990-10-27
Abstract: The process described for producing locket-halves comprises the following steps: A locket-half body is formed from a first sheet. An annular groove (2) is stamped in a second sheet, the external diameter of the groove being substantially the same as that of the locket-half (9). The part (6) of the second sheet (1) enclosed by the inner edge (4) of the groove (2) is removed, thus giving an annular plate. The locket-half body (9) is laid with its edge in the groove (2). The edge of the locket-half body (9) is welded to the annular plate. The part of the second sheet (1) which, after the groove (2) was stamped in it, extended beyond the outer edge (3) of the sheet (1) is then separated from the annular plate.

Title: Method for producing tubular moulds for continuous steel casting - without employing additional finishing processes
Inventor: SBRANA ARMANDO
IPC: B22D11/057
Filed: 1990-12-06
Abstract: Mfg. tubular curved moulds of copper (alloys) for continuous steel casting installations is characterised by: first end of tubular straight blank is provided with a cold-formed sloping shoulder (3). The blank is then transformed by a transverse force into a curved workpiece (11). A mandrel (12) whose outside geometry corresponds to the desired inside geometry of the mould is inserted into the workpiece (11) with appropriate clearances. The workpiece (11) is driven through the die (15). The mandrel is extracted by means of the die elements (21) from the mould thus produced. The blank is pref. chosen so that there is a constant clearance (G) everywhere between its inner surface and the mandrel (12). Whilst the workpiece (11) is driven through the die (15), both the end (16) of the mandrel and the die move in step in the plane of the curved axis of the mandrel. The sloping end (3) of the tube can be produced in a device incorporating sectors with stepped or sloping contours; an appropriate combination of the vertical motion of the tube and the radial motion of the sectors produces the required shape of the shoulder. USE/ADVANTAGE - Used to produce moulds for continuous steel casting installations. It does not use such laborious and costly processes such as grinding and lapping or chemical processes (which are employed by the traditional methods), in order to achieve the required surface quality and the shape (taper, in particular) of the mould. It has greater dimensional accuracy than an earlier known method based entirely on plastic forming.
Patent DE-4039223-A1 (DE)
IPC: C11D10/04
Filed: 1990-12-08
Abstract: Liquid detergents consist nowadays in the surfactant component mainly of petrochemical-based surfactants; the biodegradability and the ecotoxicity usually do not correspond to those of surfactants based on natural raw materials. A mixture is therefore proposed for liquid detergents, which contains a very high proportion of surfactants from renewable raw materials; the washing results and biodegradability are outstanding. The mixtures according to the invention consist of fatty alcohol ethoxylate, soap and anionic surfactant, plus alkyl polyglycoside.

IPC: C05F17/02
Filed: 1991-11-14
Abstract: The assembly to reduce biological waste matter into a compost has storage and working surfaces contained within the operating range of a crane. The storage and working surfaces can be covered wholly or partially. The roof, on supports pref, has a crane assembly with a gripper to deposit the material on a belt and for sorted material to drop into a shredder.
