Inventor: RAETHEL D
IPC: F24H3/06
Filed: 1990-01-31
Abstract: A heater, in particular a motor vehicle heater operated with liquid fuel in which the fuel to be fed to the burner of the heater is preheated using the thermal energy of the combustion gases in the discharge area of the heater to guarantee reliable operation of the heater even at low temperatures, and to prevent paraffin separations, especially with diesel fuel in advance of filter devices in the fuel supply of the burner. For this purpose, a fuel preheating pipe section is provided that can be made in the form of a spiral-shaped pipe loop and that is placed in the flow of combustion gases, which have passed through the heat exchanger of the heater. Since the fuel is warmed in the fuel flow pipe before passage through the filter device, clogging of the filter device is avoided. In accordance with various embodiments the fuel preheating pipe section can be placed in an exhaust gas collecting chamber of the heater or in an exhaust gas discharge connection. Another embodiment feature includes the provision of a second heat exchanger that warms the fuel to being fed to the internal combustion engine using the liquid coolant that was previously warmed in the motor vehicle heater and which also serves as the heat exchange medium for the heat exchanger of the heater.

Abstract: In preventing a patient from being administered an erroneous anaesthetic, an incorrect concentration of anaesthetic or a mixture of anaesthetics, it would be advantageous if anaesthetic system were equipped with a device capable of identifying anaesthetics in anaesthetic system. A device (66) is described for simple and reliable identification of anaesthetics in a novel way. The device (66) identifies anaesthetics by having a thermal element (74) vary the temperature of at least some of the anaesthetic so it undergoes a change in state between two states of aggregation, e.g. condensation from the gaseous state to the liquid state, determining a transition temperature for the change in state and identifying the anaesthetic from the determined transition temperature. The condensation point temperature can be determined by sensing the capacitance between two conductors (72A, 72B) or sensing changes in the resonance of an oscillating crystal (82). <IMAGE>

Abstract: A circuit for generating an output voltage which is used during active time periods and not during inactive time periods. A DC/DC converter converts an input voltage to the output voltage. During the inactive time periods, a capacitor is charged with a quantity of charge which is then used to generate the output voltage during the active time periods. The quantity of charge is generated by a current from a current generator. The current is lead to the ground via the capacitor and a diode. As the capacitor is charged more and more, the current diminishes to zero. A control voltage switches the circuit during the active time periods so that the output voltage is obtained. The circuit can be used in a radio transmitter for portable radio equipment, in which the radio equipment is used in a radio system where transmissions occur in bursts.

Abstract: In a rotor for a centrifugal separator there is delimited at one rotor end a distribution chamber (24) for a pressurised liquid supplied to the rotor for being cleaned from particles, and at the opposite rotor end there are liquid outlets arranged for reaction drive of the rotor. The liquid outlets open on the rotor outside in a liquid free space radially spaced from the rotational axis of the rotor. The separation chamber (7) of the rotor, which is situated between the distribution chamber (24) and the outlets (27), contains arcuate separation discs (11), which are distributed around the rotational axis (10) of the rotor and formed such that a lot of axially extending separation channels are delimited, which have a relatively small through-flow resistance to liquid to be cleaned. The separation channels extend axially from the distribution chamber (24) to a collecting chamber (25). The collecting chamber (25) communicates with an outlet chamber (26) at a radial level in the rotor corresponding to that of the radially innermost parts of the separation discs. By the invention efficient separation can be accomplished and the largest possible part of the pressure of the supplied liquid can be used for the rotation of the rotor.

Abstract: Innretningen (40) har en sensor (41) plassert på den første enden (42) av en avlang konnektor (43) ved hjelp av et fast grensesnittledd (79). En registreringsenhet (44) er plassert på den andre enden (45) av konnektoren (43) motsatt den første enden (42). Konnektoren (43) er bøybar innenfor et forhåndsfastsatt kurvaturområde. Når innretningen (40) blir utplassert i sjøen, er den tilpasset for fritt fall gjennom vannmassen og å lande på havbunnen slik at sensoren (41) havner på avstand fra registreringsenheten (44): Lengden av konnektoren (43) er dynamisk variabel innen et forhåndsfastsatt område, for å eliminere eller minimalisere kobling av mulig vibrasjon i registreringsenheten (44) til sensoren (41). Den fysiske adskillelsen mellom sensor (41) og registreringsenhet (44), sammen med de mekaniske egen-. skapene ved konnektoren (43) sikrer at sensoren (41) er i hovedsak vibrasjonsmessig avkoblet fra registreringsenheten (44). Med andre ord vil ikke massen i registreringsenheten (44) hindre sensoren (41) fra å reagere på seismiske bølger, og mulig vibrasjon i registreringsenheten (44) for eksempel på grunn av eventuelle strømninger i vannet som flyter nær registreringsenheten (44) i hovedsak ikke bli overført til sensoren (41). Følgelig utgjør konnektoren (43) en positiv mekanisk forbindelse mellom sensoren (41) og registreringsenheten (44) når det gjelder maksimal avstand, men ikke når det gjelder seismiske eller strømfremkalte vibrasjoner.
