Title: Inductive appts. for measurement of travel or angular movement
Inventor: DOBLER KLAUS DR DR ING
IPC: H01F21/10
Filed: 1994-02-28
Abstract: The two coils (1, 3) operating on the eddy-current principle are wired conventionally to a processor (5) which evaluates the signal variation due to a metallic damper (2) sliding in a direction (S) parallel to a scale (4). The novelty resides in the shape of the coils which are trapezoidal with width (b, b') decreasing steadily towards the ends of the scale. The angle (alpha) characteristic of the trapezoids is advantageously determined experimentally with regard for the desired range of linear measurement. Where no compensation of temp. drift is required, a single coil (1) is sufficient.

Abstract: A device for adjusting enclosed thread brakes on twisting machines, especially two-for-one twisting machines. Arranged within the twisting spindle is an enclosed thread brake, with a brake ring (12) which is arranged on a brake-ring carrier (12.1-13) movable counter to a spring force (17). Arranged on the brake-ring carrier (12.1-13) is an annular piston (14) guided in an annular cylinder (15) which is connected to a compressed-air conduit (16). Arranged on the circumference of the brake-ring carrier (12.1-13) is a first toothed quadrant (18) with downward-directed teeth, opposite which is located a second toothed quadrant (19) with upward-directed teeth. During the displacement of the brake-ring carrier (12.1-13), an inward-projecting supporting stop (20) engages into the slots formed between the teeth of the toothed quadrants (18, 19). The tooth flanks of the two toothed quadrants (18, 19) have oblique faces, such that, during an up-and-down movement of the brake-ring carrier (12.1-13), a rotation of the brake-ring carrier through predetermined angular amounts takes place, the said rotation bringing about an adjustment of the enclosed thread brake as a result of the bearing of the supporting stop (20) against different supporting shoulders in the first toothed quadrant (18). The adjustment of a plurality of enclosed thread brakes takes place simultaneously from a central control apparatus by means of compressed-air pulses transmitted via a common compressed-air conduit. <IMAGE>

Title: Method and device for profiling bristle zones
Inventor: HORL OTMAR
IPC: A46D1/05
Filed: 1994-07-16
Abstract: The invention relates to a method and a device for introducing profile sections into bristle zones of toothbrushes. In order to be able to process the fibres in different partial regions (21, 22) of bristle zones separately, in particular to be able to shorten them by means of a straight milling cutter or a flat grinding wheel, the fibres in the partial regions (22) of the bristle zones which are to be left untouched by the processing tool are held by laterally deflecting the free fibre ends in the longitudinal direction of the respective partial region (22) of the bristle zones with spacing from the processing plane (20) of a processing tool. If the method is applied in several stages, fibres from different partial regions (21) of the bristle zones being processed in each case, almost any desired profile cross-sections can be made in the bristle zone (2), both in the longitudinal and in the transverse direction. In this case, in each processing stage, processing can take place with straight processing tools, e.g. straight milling cutters. The use of expensive profile milling cutters can thus be dispensed with. <IMAGE>

Patent DE-4440320-A1 (DE)
Title: Method and apparatus for detecting environmental pollution by chemicals in aqueous samples using bioindicators
Inventor: PAULI WILFRIED DR RER NAT
IPC: C12Q1/02
Filed: 1994-11-11
Abstract: In this method, the negative chemosensory behaviour of ciliates is used as a measure of chemical pollution by impregnating the end of a cotton bud with sample solution and then immersing it briefly in a test organism suspension. After contact between the ciliates and the sample solution, the organisms which have penetrated into the cotton are washed out in a separate vessel and the number thereof is determined. Ciliates react to even low concentrations of a large number of environmental contaminants with an avoidance and flight behaviour whose intensity is concentration-dependent. Whereas this behaviour impedes the penetration of exposed organisms into the cotton, cells which have been contacted with an unpolluted reference solution collect on the fibrous matrix of the cotton within a few seconds. Comparison with unpolluted control samples permits, on the basis of the cell count, a quantitative measure of the negative chemosensory reaction and thus of the chemical pollution.

Title: Inverter-driver e.g. for electric vehicle AC voltage network
Inventor: KOKES MICHAEL DIPL ING
IPC: B60L1/00
Filed: 1994-12-24
Abstract: An AC power supply has a bridge inverter whose transistors are triggered by a control voltage at a frequency which is in resonance with a series resonant circuit (l1,c1,l2,c2) in the bridge branch. The AC output passes to a series of diodes (dr1 to dr4) for voltage limiting. The energy stored in the resonant circuit is passed to the DC source during load decrease.  In normal operation, the voltage-limiting diodes do not conduct. The control voltage is transformed by a factor of 5 to 40, the transformer being a leakage reactance type. Apart from the primary and secondary windings, it has a clamping winding close to the secondary.
