Title: Screw device with a freely positionable screw spindle
Inventor: FISCHER GERNOT
IPC: B25J15/00
Filed: 1987-02-16
Abstract: A screw device with a screw spindle freely positionable by means of a handling appliance and, in particular, by means of an industrial robot is described. The screw device according to the invention is characterised by the following features:   - the screw spindle is attached to the supporting arm of the last axis of the handling appliance so as to be offset relative to the axis, - the last axis of the handling appliance has a gripper which is arranged in such a way that it allows the handling of the screw, of screwing accessories and/or of screw-on parts in a manner which is monitored in terms of position and space.   This allows a fault-free operation of joining by screwing, even in the case of screwing operations which are oblique in space and even in the case of a handling appliance having only little path accuracy.

Title: Method of wind energy utilisation by means of a wind-jet turbine
Inventor: TEPE WALTER PROF DR
IPC: F03D3/04
Filed: 1987-07-18
Abstract: By combining a vertical-axis turbine with two deflector plates (8, 9) and a cylinder rotating in the wind (4), a wind-jet turbine is created which faces into the wind automatically due to the wedge position of the deflector plates. The turbine, rotating cylinder (4) and deflector plates (8, 9) are connected at top and bottom to double legs (10), and move on wheels about a fixed axle (11) on a circular track (17) which absorbs their weight and the wind pressure. The deflector plates (8, 9) concentrate the incident wind to a jet in the ratio 1 to 0.55-0.59, with the rotating cylinder (4) stabilising the wind jet in the prolongation of one deflector plate (9), and guiding it into a circular path. The blades (6) of the vertical-axis turbine rotate coaxially about the rotating cylinder (4), which is rotated by the wind jet by means of vanes (5), utilising the lift and resistance of the wind jet to obtain energy, with an efficiency of 35-45%. The turbine blades are of lamellar design and guide the wind flow so that 60% of the blades are impacted. The cost/benefit ratio of the wind-jet turbine is very good. <IMAGE>

Title: Apparatus and process for the production of a fibre pad
Inventor: FARRINGTON ALLAN P
IPC: D04H1/72
Filed: 1988-09-21
Abstract: A pad (45) is formed by bringing separate fibre materials (30, 32) into contact with two separate card rollers (10, 20) which are arranged parallel to one another and which are rotatable in opposite directions to one another. The fibres from the two card rollers (10, 20) are guided through a mixing zone (40) and collected in pocket moulds (402) which are moved on a conveying screen (42) running parallel to the axes of the card rollers (10, 20). A deflecting plate (60) can be inserted into the mixing zone (40) and is effective for influencing the lateral or cross-sectional composition of a cloth formed by fibres collected in the moulds. If different fibre materials are fed to the card rollers along the latter, the vertical composition of the cloth is changed. As a result of the pockets in the moulds, the pads are produced as individually shaped products (Figure 1). <IMAGE>

In the event of nonperiodic switching of the controller (21), said circuit firstly switches the latter to the output current of zero and then switches to an output current (13) which is smaller than the pickup current of the electromagnet and larger than the minimum triggering current (14) of the thermal trigger (15). <IMAGE>
Patent DE-3901518-A1 (DE)
Title: Method for the cooling of filaments emerging from spinnerets
IPC: D01D5/088
Filed: 1989-01-20
Abstract: It is known to cool the filaments emerging from the spinnerets by means of a coolant stream of air or water. However, in the case of fibres spun at high speed, air has too little a cooling effect. Water is more advantageous here, but the fibres drawn through a water bath have to be additionally dried. The invention proposes the use of a water mist which is sprayed transversely relative to the spun thermoplastic fibres. The moisture content of the water mist is to be controlled in dependence on the spinning speed, specifically in such a way that, when the fibres are being deposited, the fibres are dry.

Title: Method for measuring the hysteresis of soft-magnetic material
Inventor: FRIES JUERGEN DIPL PHYS
IPC: G01R33/14
Filed: 1989-01-27
Abstract: In this method, a workpiece (10) of this material is exposed to a largely homogeneous magnetic field having a continuously variable field strength and the magnetic induction (B) in the workpiece (10) is measured by integration of the voltage induced in a measuring coil (11) surrounding the workpiece (10) and is correlated with the magnetic field strength (H) prevailing in each case. To avoid elaborate preparation processes on the workpiece (10) (turning, grinding) for the measurement, workpieces (10) which are rod- or strip-shaped and have a very large ratio of length (1) to diameter (d) are used for the hysteresis measurement. As a result of this large l/d ratio, the shear in the magnetic circuit, which is not closed, is small and the measurement error obtained is negligibly small. <IMAGE>
