Granted: 1989-02-16
Abstract: A method for using selected strains of Streptococcus lactis subspecies diacetilactis, which have been modified to be non-lactose fermenting, for the preservation of foods containing lactose is described. The subspecies is more generally known as Streptococcus diacetilactis. The selected Streptococcus diacetilactis strains have been modified by curing to remove at least one natural plasmid which controls the fermentation of lactose to lactic acid while retaining the ability of this subspecies to inhibit bacterial spoilage in foods. The plasmid removed by curing is about 41 megadaltons (Mdal) in mass. The method using the modified strains of Streptococcus diacetilactis is particularly adapted for the preservation of milk products.

Abstract: © An intrinsically safe battery pack arrangement for electrically powering electrical devices is disclosed. The power pack has a device for electronically determining a short in a cable or device and switching off the voltage to the power pack. The electronic device includes a transisterized circuit for sensing and controlling currentthrough the cable. When the currentex- ceeds a predetermined maximum, the circuit limits the current in the cable to a maximum value. The circuit is latched in the off position when the short is present for an extended time and the circuit may be reset after the short is removed and the problem corrected. This form of circuitry in power packs for use with mining equipment such as lamps, provides a unit which will not cause hazardous sparks when shorted thereby constituting an intrinsically safe device for use in mines.

Abstract: A method and apparatus is provided for protecting against lightning. An atmospheric potential tapping member is disposed for this purpose in the atmospheric field prone to lightning to collect a voltage (Uc) which, before there is a real threat of the lightning striking, has a value which remains within a lower voltage range (Ub) a capacitor is progressively charged with the voltage Uc and a few tens of microseconds before there is a real threat of the lightning striking a given place, the atmospheric field will undergo a sudden increase and will therefore influence, relatively in the same way, the voltage collected which will rise up to and into a range (Uh) of voltages greater than that (Ub) where it was situated up to then. This potential gradient is detected with respect to time, and the evolution of the potential gradient (dv/dt) detected with respect to time is monitored in this upper range (Uh) of voltages. When the potential gradient detected with respect to time rises beyond a predetermined threshold, the capacitor is caused to discharge into a discharge circuit.

Abstract: Method and apparatus for spectrophotometrically determining the concentration of a number of hemoglobin derivatives comprising at least deoxyhemoglobin and oxyhemoglobin or parameters derived from the concentration of individual hemoglobin derivatives, in particular the oxygen saturation fraction, in whole blood, in which light is transmitted to the blood under test, the modification on the light transmitted to the blood which the blood causes is determined at a number of individual wavelengths, and the concentrations (or the derived parameters) are determined on the basis of the light modification at the individual wavelengths and on the basis of predetermined coefficients representing the light absorption characteristics of each of the hemoglobin derivatives at each of the individual wavelengths, any error on the determination values due to turbidity being substantially compensated for by utilizing predetermined coefficients representing an absorption characteristic of turbidity at each of the wavelengths. The measurement is normally performed at a number of wavelengths which is at least equal to the number of hemoglobin derivatives to be determined plus one. Although the turbidity-caused contribution to the total reduction in the light transmission is not based on any direct proportionality between the reduction in light transmission and the concentration of the turbidity-causing components (such as is the case with the hemoglobin derivatives), the "absorbances" caused by the turbidity at each particular wavelength may simply be eliminated from the equation set from which the concentrations of the hemoglobin derivatives are calculated.
