Abstract: A combined trigger and concealing device for an automatic sprinkler head comprises a first plate attached to a second plate by a heat fusible material in a partially overlapping manner. Each plate is formed with an aperture which receives an actuator depending from the bottom of the sprinkler head. The trigger device depends a preselected distance from the bottom of the sprinkler head body and has an outer dimension which causes the trigger device to conceal the internal components of the sprinkler head from view. An annulus defined between the periphery of the device and the bottom of the sprinkler head permits heat energy to be received by the inner surface of the trigger device.  Conduction of heat energy from both the inner and outer surface of the trigger device permits the heat fusible material to be expeditiously raised to the preselected separation temperature. This uniform thermal conduction minimizes the response time of the automatic sprinkler head while maintaining a highly aesthetic appearance.

Abstract: Techniques of service-rate controls in ATM switches are described, and apparatus for their implementation are devised. The techniques fall in two categories: frequency domain controls, and time-domain controls. The regulators control the service rate on a per-class basis or on a per-connection basis. Some class regulators operate at very high speeds of the order of several gigabits per second and cover a medium number of classes, 32 for example. Other regulators operate at high speeds of the order of several-hundred megabits per second, and cover a very large number of classes, e.g., 10,000. A compound regulator which combines both types of regulators is also described. The compound regulators extend the range of controllable classes considerably, covering some 200,000 classes. The main advantages of the regulators of the invention are simplicity, robustness, and high performance.

Abstract: The device (10) and method are used for ventilating an offset pocket space (12) located in a drying section of a papermaking machine by injecting air from a t least one heated dry air supply inlet (11). The offset pocket space (12) is situat ed between three axially-parallel drying cylinders (20) over which consecutivel y runs a paper web (14). A first and a third of these cylinders (20) are vertically spaced from a second one. The paper web (14) is pressed against the first and the third cylinder (20) by a felt (16) which further runs around a felt roll (26) havi ng a rotation axis parallel to that of the cylinders (20). The felt roll (26) is disposed between the three cylinders (20) in an offset position which is closer to th e first cylinder (20) than the third cylinder (20). The device (10) comprises a first air outlet (50) where a first air stream i s directed into a cleft (30) defined where the felt (16) and the felt roll (26) join, a nd a second air outlet (52) where a second air stream is directed in close proximity of the felt (16) at a location which is upstream the cleft (30). The second air stream i s in a direction which is substantially opposite the running direction (R) of the felt (16). In use, the device (10) and the corresponding method allows the first air strea m to flow throughthe felt (16) and to lift the paper web (14) away from the felt (16) so as to reach the offset pocket space (12). The second air stream creates an a ir curtain to lower the pressure in a zone between the first (50) and the secon d (52) air outlet, thereby establishing a zone of reduced air pressure in close proximity of the felt (16) at a location which is immediately upstream the cleft (30).</S DOAB>

Abstract: The invention relates to a burner (1) for liquid fuel, notably extra light fuel, which can be controlled by a burner control device and comprises an air circulator (3) driven by a motor (4). A burner pot (45) comprises an evaporator chamber (39) and an atomization organ (30) positioned in said evaporator chamber (39), which can be heated by means of an electric heating device (20). According to the invention a cylindrical flame holder (11), along whose perforated outer surface the flame is generated during burner operations, is placed onto the evaporator chamber (39). Means are provided for, for example a deflection collar (12a, 12b) which partly encloses the flame holder (11), by means of which a part of the hot exhaust-gas flow is deflected in such a way that it heats the evaporator chamber (39) from the outside. The output signal of a temperature sensor arranged at the burner pot (45) is transmitted to the burner control device. The burner control device cuts the electric heating device (20) switched on when the burner (1) was started as soon as the actual value of the temperature measured by the temperature sensor (8) at the burner pot (5, 45) exceeds a setpoint which can be set in the burner control device. As a result, no further external electrical energy is required after the start of the burner (1). The burner (1) can be modulated at a ratio of 1:3, for example between 5 and 15 kW, and is suitable for heating residential buildings with correspondingly low heat requirements by burning extra light heating fuel.

Abstract: A modal analysis method and apparatus for acoustically determining dynam ic vibration characteristics of a structure, including natural frequencies, mod e shapes and damping factors, is based on a Multiple-Input-Single-Output (MISO ) model. The method and apparatus involve generation of an acoustic excitation signal toward n spatially distributed locations associated with the structur e while the latter is held to allow vibration thereof, one of the locations being chosen as a reference location. A series of microphones are disposed at the locations to produce m complementary sets of n input acoustic pressure-related electrical signals, one of these being chosen as a reference signal associated with the reference location. A Fourier analysis is performed on the sets of input acoustic pressure-related electrical signals to provide corresponding sets of correlated input acoustic pressure-related data in the frequency domain including reference data associated with the reference signal. A vibration transducer such as an accelerometer is used to sense induced output vibration in response to the acoustic excitation at a reference point on the excited structure corresponding to the reference location to produce m complementary sets of output vibration response electrical signals, which are then converted through Fourier analys is into corresponding sets of output vibration response data in the frequency domain. Then, from relations between m corresponding complementary sets of n input transfer functions characterizing the correlation between each set o f input acoustic pressure-related data and the reference data from one hand, a nd m sets of output vibration response data on the other hand, the structural transfer functions characterizing each said set of input acoustic pressure- related data are obtained. Finally, the dynamic vibratory characteristics of the acoustically excited structure are derived from the resulting structural transfer functions through usual calculation techniques.

Abstract: The invention relates to an apparatus and a method for deter-mining an approximate value for the stroke volume and the cardiac output of a person's heart. The apparatus and method employ a measured electrical impedance, or admittance, of a part of a person's body, namely, the thorax. This part of a person's body is chosen because its electrical impedance, or admittance, changes with time as a consequence of the peri-odic beating of the heart. Accordingly, the measured electri-cal admittance or impedance can provide information about the performance of the heart as a pump.
