Patent EP-0574646-A1 (EP)
Inventor: POMA ALBERTO
IPC: H03K17/082
Filed: 1992-06-16
Abstract: A resistor (R S ) is in series with the drain-source path of the MOS power transistor (M1). The supply terminal (s) of a transconductance operational amplifier (A) is connected to the output of a voltage-raising or charge pump (CP) circuit which can output a voltage higher than that of the voltage supply (V s ) to which the drain of the MOS transistor (M1) is connected. The inputs of the amplifier (A) are connected to the resistor (R S ) and its output is connected to the gate of the MOS transistor (M1) so that, in operation, the maximum current flowing through the power transistor (M1) is limited to a value proportional to a reference voltage (V R ).

Abstract: A circuit for converting a first logical level into a second one. Even when the voltage of a power supply is increased, the low level of the output voltage of a switching circuit (25) is suppressed from increasing, and accordingly an output buffer (28) is always made operable, because voltage limiting elements (26, 27) suppress the output level shift voltages of level-shifting devices (21, 22) connected to the output ends of input transistors (Q₁, Q₂) to predetermined values.

Title: Apparatus and method for aseptically reconstituting beverages.
Inventor: HEATH HAROLD R
IPC: B01F5/04
Filed: 1992-03-18
Abstract: The invention provides a method and apparatus for reconstituting beverages wherein superheated reconstituting liquid and beverage concentrate are delivered into a mixing chamber having an adjustable volume. The mixing chamber is the volume between two coaxially arranged tapered elements which are disposed one inside of the other. Final beverage product emanates from an aperture in the tip of the outer tapered element. At least one tapered element can be displaced in the longitudinal direction so that the volume of the mixing chamber decreases and approaches zero as the tapered elements are moved closer together. Thus, when the system is shutdown the volume of the mixing chamber is allowed to approach zero so that very little product is susceptible to degradation in the mixing chamber due to prolonged exposure to high temperatures during a shutdown. The reduced volume mixing chamber may be flushed with reconstituting liquid. In addition, the temperature of the mixing chamber can be controlled during a shutdown by adjusting the temperature of water contained within the walls of the tapered elements.

Title: Automatic cutout with an arc extinguishing chamber.
Inventor: OSTERMANN WERNER
IPC: H01H73/18
Filed: 1992-12-04
Abstract: The automatic cutout switch has inside its housing (1) an arc chamber (2) containing a stack of quenching plates (3) which communicates behind a slotted (2b) separating wall (2a) with an outwardly open blow-off chamber (4). In order to reduce considerably the ejection of hot conductive arc gases and also largely to prevent the exit of flames from the housing at breaking capacity, the blow-off chamber (4), consisting of two half shells (1a, 1b) of the housing (1), has several staggered walls (4a) transversely to the main direction of flow, like a labyrinthe which considerably lengthen the gas flow path. In addition, the walls (4a) have, on their facing upper sides substantially parallel to the separating plane of the half-shell (1a, 1b), comb-like projecting pegs (4a') which cool the arc gases and cause them to eddy. The walls (4a) are preferably arranged at least partially to inter-engage at a short distance from each other alternately at each half-section (1a, 1b).

Abstract: In the method according to the invention for controlling a recirculating pump in a heating system, the recirculating pump is switched on and off periodically when the outside (external) temperature (TIst) (Tactual) undershoots a first threshold value (TS1). The ON-OFF phase ratio is determined by the extent of the undershoot in such a way that the duration of the OFF phase is shorter the larger the undershoot. The recirculating pump is switched on permanently when the external temperature (TIst) undershoots a second threshold value (TS2). This method protects frost-endangered parts of the heating system reliably against freezing up, without the recirculating pump being in operation unnecessarily. <IMAGE>

Abstract: Pumping light from an optical pumping source (24) is incident on an Er-doped fiber (22) through a multiplexer (26) to pump Er. When signal light is incident on the Er-doped fiber (22) through the multiplexer (26) in this state, the signal light is amplified by stimulated emission of pumped Er. This amplified signal light is attenuated by a high-loss optical fiber (30) and is output externally through a splitter (36) and the like. Meanwhile, part of the amplified signal light is fed back to a driving source (42) of the optical pumping source (24) through the splitter (36) so as to be used to adjust the gain of the optical fiber amplifier. With this operation, the output signal power is kept constant. In this case, since the high-loss optical fiber is connected to the output terminal of the Er-doped fiber, the noise figure of the optical fiber amplifier can be kept small over a wide range of input light intensities.

Abstract: A communication network (VCN) offering an ETHERNET service to a plurality of local terminals (ELT1, ELTN, TLT1, TLTN1-8), typically computers, is proposed. Flexibility and cost are enhanced with respect to existing ETHERNET networks by emulating an ETHERNET network towards the local terminals whilst pooling complex functions in a computer network server (LANS) connected to the backbone ATM netork (BB). 
     This is achieved by coupling the local terminals, preferably separately, to standard ETHERNET links (ELN, TL1, TLN1-8) and by terminating these links in interface modules (EIM1, EIMN, TIM1, TIMN) converting the ETHERNET frames from the local terminals in ATM packets destined for the central server which stores these packets in an input buffer (IB1-X) and performs the above complex functions, particularly also the transmission of these packets to appropriate ones of the interface modules. Buffer overflow is avoided by transmitting backpressure signals (BP1-X) to the interface modules so as to control them to halt transmission on the computer links. 
     The present invention is particularly well suited for early deployment of ATM networks as their inherent high bitrate transmission capability is used to provide ETHERNET type services at a lower cost per terminal whilst employing standard access technology.

Abstract: A semiconductor device is provided which has a plurality of output drivers whose slew rates are differentially controlled. The slew rates of the output drivers are controlled by a control means such that the slew rate of at least one of the output drivers is different than the slew rate of another output driver. Preferably, the slew rates are differentially controlled such that an output driver that drives a signal that reaches an output pin of a semiconductor package later slews at a faster rate than an output driver that drives a signal that reaches an output pin of a semiconductor package earlier. In this way all of the output pins of a semiconductor package can be driven to change states at approximately the same time. The slew rates of the output drivers can be differentially controlled through the utilization of programmable resistors.
