Abstract: To determine the backlash in an arrangement in which a motor moves a load via a transmission mechanism, a transducer is used which is present anyway in conventional production machines and which measures an angular position or translatory position of the drive element or a derivative of this quantity. Via the transducer the effect of the backlash on the actual position of the drive element is measured, the actual position being different from the desired position, which is defined by the forces or torques acting on the drive. On the basis of a frequency analysis, quantities can be derived which permit the use of threshold criteria. For example, the drive is driven with a periodic signal which is close to the absorber frequency, i.e. a frequency at which the absorption by the transmission mechanism is greatest.

Abstract: The invention relates to pearlescent pigments with a platelet-shaped substrate comprising metal oxide and having a first and a second protective layer, said metal oxide having a refractive index of greater than 1.8, there being on the platelet-shaped substrate a first protective layer comprising cerium oxide and/or cerium hydroxide and a second protective layer of SiO2, applied to which is an organic chemical aftercoat comprising at least one silane having at least one functional bond group and at least one silane without a functional bond group, it being possible for metal oxide layers other than cerium oxide and SiO2 to be disposed between the first and the second protective layer. The invention further relates to a process for preparing these pigments, and to the use thereof.

Abstract: The invention relates to a colored, platelet-shaped metal pigment comprising a base pigment comprising metal, a layer of silicon dioxide, and, subsequently, a layer or two or more layers comprising one or more coloring materials. The invention further relates to a method for the production of a colored metal pigment of this kind, and also to the use thereof in cosmetics.

Abstract: The invention described here is a circuit protection device based on the principle of a plasma limiter. A plasma limiter uses an electrode such as a very sharp tungsten needle in an easily ionized gas to perform field enhancement using the interference voltage to initiate avalanche breakdown of the plasma. The gas becomes conductive, causing the interference voltage to short-circuit to ground thereby protecting the transceiver Integrated Circuit (IC). This device protects IC's that can be damaged by voltages greater than about 15 volts when damaging voltages have occurred on the wire(s) for a brief time. The damaging voltage creates an electromagnetic field that is enhanced by the sharp electrode thereby causing the easily ionized gas to become plasma and conduct between the wire and grounded electrode. This conduction prevents the damaging voltage on the wire from becoming so great that IC's become damaged. A protection module consists of devices to protect one or many signals in a single module.

Abstract: With the intention of performing an optimal cutting of the hind feet (8) of the half carcasses (4), which are advanced stepwise on an overhead conveyor (6) suspended in the hind feet (8), there is indicated a method and a plant for performing an optimal hind foot cutting. According to the invention, cutting of the hind feet (8) occurs by the half carcasses (4) being gripped by pivoting gripping mechanisms (26) the clear of which in the gripping position not allowing the heel joint (29) to pass through this. As the variation of the thickness of the heel joint on a carcass is very small, a lifting of the ham (32) of the half carcass by displacing the gripping mechanisms (26) will result in the position of the thickest point of the heel joint being well-defined, whereby there is achieved a very great uniformity of the hind foot cutting by the same displacement pattern of the gripping mechanisms (26) in cross-wise direction in relation to saw blades (30) situated in a plane well-defined in advance.

Abstract: In the primal cutting-up of half carcasses of animals (12), vision systems are known whereby the determination of one or more fix points on the carcasses takes place, and where on the basis of the position of these points a visualisation of the ideal cut line is effected. But the primal cutting-up of carcasses (12) has hitherto been carried out with manually-operated saws on the basis of operator evaluation. However, the use of manually-operated saws involves the possibility of deviations in relation to the ideal cut line, and the manual work is very monotonous and fatiguing for the operators.
