Abstract: A gravity driven cooling system pool (34) is disposed at an elevated location with respect to the locations of nuclear fuel rods in a pressure vessel (12) in a containment (14). In the event of a loss of coolant in the pressure vessel, steam pressure is initially reduced by venting (20) the steam into the containment or a closed suppression pool (28) containing a quantity of water (24) under a large air space (26). The suppression pool condenses sufficient steam to lower the steam pressure in the pressure vessel so that water can flow by gravity from gravity driven cooling system pool to flood the fuel rods in the pressure vessel. An isolation condenser (40) is submerged in a large supply of water (50) elevated with respect to pressure vessel. Steam is admitted to the isolation condenser, or heat exchanger, where it is cooled by boiling the water surrounding it. This steam is vented to the atmosphere. A depressurization valve (32) vents steam from the pressure vessel into the containment to aid pressure reduction, and thus to aid the gravity flow of coolant. Later, as the pressure in the pressure vessel is reduced by heat removal in the isolation condenser, steam in the containment is permitted to flow from the containment, through the depressurization valve (32) and thence to the isolation condenser, or heat exchanger.

Abstract: Control units of electronic apparatuses, especially of entertainment electronics apparatuses or of domestic apparatuses such as washing machines and electric cookers, are often located, including their switching units, in pivoting flaps which can be closed up when the control units are not in use, for visual or safety reasons, and can then not be seen or operated from outside. The switching units are normally connected to the apparatus electronics via cable harnesses or flat-strip cables, the frequent movement of which results in a certain susceptibility to faults. A pivoting control unit is described here which allows a purely mechanical operation of the switching units (2) seated on printed-circuit boards by means of linear plungers (5) which are supported in said control unit and can be operated with the control unit pivoted out or partially pivoted out and by means of connection parts (6). The susceptibility to faults is thus very greatly reduced and the user friendliness significantly increased. <IMAGE>

Abstract: A disposable breath alcohol tester is disclosed which includes a transparent housing defining an interior chamber. A tube extends through the housing chamber so that one end of the tube is open to one side of the chamber while the second end of the tube is open exteriorly to the opposite side of the chamber. An inflatable bladder is connected to the second end of the tube. The tube contains an alcohol reactant substance which changes color whenever the alcohol content of exhaled air passing through the tube exceeds a predetermined amount and at least a portion of both the tube and the housing are transparent so that the alcohol reactant substance can be observed. In use, the person under test inflates the bladder by blowing through the tube and thus through the alcohol reactant substance. The color of the alcohol reactant substance is then observed in order to determine the alcohol content of the exhaled breath.

Abstract: In a TDMA cordless telephone system, such as DECT, an out of lock secondary station scans all the physical channels in the respective carrier channels in order to find a system onto which it can lock. In order to expedite the scanning of the channels, the secondary station adopts a scanning sequence in which during each scan of the sequence consecutive physical channels located in non-adjacent carrier channels are scanned. Because of spill over from transmissions in the non-scanned channels it is possible to determine in what channels there are transmissions thereby possibly enabling the secondary channel to lock sooner thus saving battery power. In a modification of the scan, the signal strength in the respective physical channels may be monitored for a fraction of the duration of the physical channel.

Abstract: A sampling device (210, 1710, 1910, 2110, 2310) which can be used to safely obtain samples of biological fluids, such as, for example, saliva, urine, water, tears, and vaginal fluids. The device can include a sample container (211, 1711, 1911, 2111, 2311), a sample collector for collecting a sample of biological fluids (213, 1713, 2113, 2313), and a collection container (1714, 1914, 2155). Means (214, 1715, 1915, and 2114) can be provided, so that when the sample collector selectively receives a sample of biological fluid, an indicator activated by a preselected amount of the received sample of biological fluid indicates that the collected sample of biological fluid is of adequate amount. The sample collector may, for example, include a piston (1932, 2115) fitting closely within the sample container and a porous mass which may be compressed by the piston in the sample container to extract the sample of biological fluids. For example, when the sample container (1911) is inserted into the collection container (1914) the sample container (1911) becomes fluidly coupled to the collection container (1914) which receives the collected sample of biological fluids. In another embodiment, a sampling device (2110) may also include an assembly with at least one container (2170) containing a solution which may be used to mix with the collected sample of biological fluids.
