Abstract: A coin separator/rejector system includes a plurality of coin races which are disposed in a compact coin receiver body. The races have at least one protrusion along their length so as to deflect downwardly traveling coins and force these coins to alter both their attitude and direction of travel to encounter apertures formed in the receiver body between successive coin races. Coins of a selected diameter travel downwardly along any given coin race for ultimate deposit or credit. Coins of less than the selected diameter are directed into an alternate direction and path of travel along an alternate or secondary race where they are either credited or rejected.

Abstract: Sulfated polysaccharides, such as fucoidan, dextran sulfate, heparin and  -, x- and X-carrageenans proved to be potent and selective inhibitors of human immunodeficiency virus type 1 (HIV-1 ) in vitro. No toxicity for the host cells was noted with these compounds, so that the selectivity indexes, as based on the ratio of the 50% cytotoxic dose to the 50% antiviral effective dose, were equal to or in excess of 100. 
     Dextran sulfates of low molecular weight (5000, 8000) exhibited a significant inhibitory effect on HIV-1 at a concentration that was not markedly inhibitory to the blood coagulation process.

Abstract: A technique is described for managing data storage devices and the data stored on them. A pair of data storage devices are maintained as identical copies. The dual copy function is provided without changing any current system or application software on the host. A set of status information is maintained for each record on the data storage device. This status information includes information which allows only the changed records to be copied to the secondary device of the dual copy. This technique also provides high availability of data storage devices by swapping a failing data storage device with a good data storage device without host intervention. A joint array structure is used for routing host requests for information to and from the correct data storage device and keeping status information concerning the data storage devices.

Abstract: A lamp system (25)which erases selected portions of an electrically charged photoconductive member. The lamp has a transparent housing (118) defining a chamber (120) filled with a gaseous medium (116). A charge is induced across a selected region of the gaseous medium between spaced electrodes comprising a continuous electrode (114) and a segment of a segmented electrode (125). This causes the gaseous medium to ionize in the selected region so as to emit light rays thereat. The light rays illuminate the electrically charged photoconductive member in the selected region to discharge the charge thereat.

Abstract: According to the present invention, one surface of a resistor plate (7) is arranged to face first electrodes (4) which are formed on a first region of one surface of a semiconductor element assembly. One surface of a conductor plate (5) is arranged to face the other surface of the resistor plate (7). Pressure is applied to the other surfaces of the semiconductor element assembly and the conductor plate (5), to form junction surfaces between the first electrodes (4) and the resistor plate (7) as well as between the resistor plate (7) and the conductor plate (5) to connect them with pressure. This structure is equivalent to inserting resistors between the first electrodes (4) and the conductor plate (7). Such resistors uniformalize distributed or partial currents flowing in respective parts of the semiconductor element assembly, whereby any local current concentration can be prevented, to thereby improve switching characterizistics and controllable gate turn-off current.

Abstract: In the polarisation scrambling method for compensating polarisation fluctuations of a transmitted optical signal for an optical transmission system with heterodyne reception, the polarisation state of the transmitted optical signal is generally keyed several times during one bit period of this signal and thus very frequently. A novel polarisation scrambling method is specified in which keying is necessary less frequently. For this purpose, the keying of the polarisation state is carried out synchronously with the clock of the transmitted optical signal and the respective keying time is placed at the bit centre so that keying is necessary only once per bit period. A device for carrying out the method is described. Application for optical transmission systems with heterodyne reception <IMAGE>

Abstract: In a heating apparatus (1) for producing heated liquid and/or steam, a main container (2) contains both a liquid reservoir (3) and a heating-up chamber (10) which is considerably smaller than the latter in volumetric capacity and separated but communicating with the liquid reservoir (3) for refilling, and which is associated directly with the heating means (6) of the heating apparatus (1). Medium removed from the heating-up chamber (10) via a use outlet (11) is immediately and automatically replenished from the liquid reservoir (3), it being possible, in the case of steam production and the pressure-sealed construction of the main container (2), for the steam pressure also to be used for conveying liquid, for example from the liquid reservoir (3), via a rising pipe and an associated use outlet (12), so that either steam or warm liquid can be removed from the heating apparatus (1). As a result of the small volume of the heating-up chamber (10), whose cross-sectional extension transversely to the heated container wall (7) is substantially smaller than parallel to this container wall (7), very short heating-up times result. <IMAGE>
