Abstract: Surfactant combinations which need to have an increased viscosity on the grounds of their applications have disadvantages with regard to the tolerability by skin and the mucous membranes of the eye. Mild surfactants such as alkyl oligoglycosides or carboxymethylated ethoxylates cannot, however, be sufficiently thickened, for example with electrolyte. …<??>The surfactant combination is intended not to have these disadvantages. …<??>Therefore an aqueous combination of alkyl oligoglycosides, carboxymethylated ethoxylates, electrolyte and additives which has a synergistic thickening effect is proposed. …<??>Aqueous combinations of alkyl oligoglycoside, carboxymethylated ethoxylates, electrolyte and additives are used as a basis for shampoos, bath and shower gels and other cosmetic formulations with increased viscosity.

Abstract: The drop-down lid of a gas appliance, e.g. a cooker hob, operates a microswitch 2 in the circuit supplying power to a solenoid valve 1 controlling the gas supply. A latching circuit 4 acting through a relay 3 opens the valve 1 on closure of the manually operable switch 6 thereby ensuring that gas does not escape immediately the lid is raised if it has inadvertently been closed down on a lighted burner. The switch 6 may be coupled to an ignition switch, preferably with a time delay. A further delay may be incorporated in the latching circuit to ensure that the gas cannot be turned on by a momentary inadvertent closure of the switch 6.

Abstract: Particles contained in a liquid sample (17) are analysed by moving the particles along a detection passage (12,13) past a detector by means of a liquid flow in said passage. To reduce the time required for each sample, the sample is delivered at an input location (7,8,9) at the upstream end of the detection passage by movement of a movable container (2) carrying said sample to said input location. Immediately after commencement of the delivery of the liquid sample, the liquid flow is caused to occur in the detection passage. 
     Washing liquid is supplied to the input location (7,8,9) by means different from said container which carries the sample.

Abstract: A calibration solution, which is used when measuring the ion concentration of solution under examination such as blood or other body fluids using a pH sensor or like ion sensor with a solid electrode, is prepared by adding NaCl to a standard buffer solution and thus setting the ionic strength of the solution to be substantially identical with the ionic strength of solution under examination. A sensor calibration method is also disclosed, in which at least two reference calibration solutions having different pH values are prepared, the electromotive force of the sensor in these calibration solutions is measured by immsering the sensor in the solutions, and a calibration formula is produced from the electromotive force for the pH values of the reference calibration solutions. A predetermined amount of bicarbonate buffer solution is added to the calibration solution to maintain a substantially constant ionic strength of the solution, thus permitting simultaneous calibration of an ion sensor and a gas sensor.

Abstract: A d.c. current source (17) provides current through a field effect transistor (12) and the effective resistance (18) of a magneto-resistive element to ground. A feedback loop including an operational transconductance amplifier (26) provides a bias voltage for the field-effect transistor (12) whereby the voltage across said effective resistance (18) of said magneto-resistive element is held constant while the resistance of said element changes. The resulting a.c. current flowing through the magneto-resistive element flows only through the feedback loop and an output resistor (25) connected across the inputs (22 and 24) of the operational transconductance amplifier (26). The amplification of the circuit is approximately the resistance of the output resistor divided by the resistance of the magneto-resistive element.

Each circuit path has a greater transconductance than the other circuit paths for its branch within a respective sub-range of the input signal range for the stage as a whole, with each path dominating the other paths for its branch within its respective sub-range. The overall bandwidth for the stage, its g m , its noise characteristics and its input voltage range are enhanced as a result. Bandwidth and slew rate may be independently optimized by the designer. Two paths are used for each branch in the preferred embodiment, with one path consisting of a bipolar transistor (Q3,Q4) and the other path either a field effect transistor (J3,J4) or a resistor degenerated bipolar transistor (Q5,R5;Q6,R6).
