Abstract: A method and an arrangement for compressing gas in a compressor station for a gas pipeline, especially in areas of permanent frost, wherein the gas is supplied in the gas pipeline to the compressor station at an entry pressure and the gas is returned to the pipeline for further transportation in the pipeline at a desired exit temperature and at an exit pressure which is higher than the entry pressure. The gas is initially compressed at least during individual time intervals to an excess pressure which is substantially higher than the desired exit pressure. The compressed gas is then cooled by heat exchange to a temperature above the desired exit temperature. Finally, the gas is further cooled to the desired exit temperature by expanding the gas from the excess pressure to the exit pressure.

Abstract: In order to achieve two-way communications at two different frequencies, and impedance matching circuit is provided between an antenna and a feeder for impedance matching at first and second resonant frequencies.  The circuit includes a first inductor which is directly coupled to the antenna.  The first inductor induces an impedance of the antenna and first antenna to be capacitive at the first resonant frequency and induces that impedance to be inductive at the second resonant frequency. The first resonant frequency is lower than the second resonant frequency.  A first capacitor is coupled to the first inductor. The capacitance of the first capacitor is selected to substantially equalize reactance components of the antenna and the first inductor and the first capacitor at the first and second resonant frequencies.  A combination of a second inductor and second capacitor are coupled between the first capacitor and the feeder.  The values of the second inductor and second capacitor are selected to match an impedance of the antenna and the first inductor and the first capacitor to an impedance of the feeder at both of the first and second resonant frequencies to thereby allow the antenna to resonate at the first and second resonant frequencies.

Title: Planar variable power divider
Inventor: MIZZONI ROBERTO
IPC: H01P1/28
Filed: 1994-03-11
Granted: 2000-05-16
Abstract: Microwave variable power divider, comprising (Fig. 1) a 3 dB directional coupler (1) (called hybrid circuit), followed on one output leg by a variable phase shifter, obtained by assemblying a -3dB directional coupler (2) with its outlets closed on movable short-circuits (6; 7) that can ensure its variability, and on the other by a 90-degree differential phase shifter (5) and an analogous variable phase shifter consisting of directional coupler (3) and movable short-circuits (8; 9), followed by another directional coupler (4). The device makes it possible to vary the power on the two output legs (12; 13) in a complementary manner by regulating the movement of the movable short-circuits.      The particular solution proposed allows the use of a planar-type technology, which can assure considerable advantages in terms of construction, dimensions and integration in more complex networks. In addition, the operating bandwidth (~ 16%) associated with low losses (0.15 dB) and minimal inband variation of amplitude at the outputs in relation to any desired power division value constitute the peculiar characteristics of this device. Lastly, the low level of passive intermodulation products allows the device to operate in multicarrier systems and the particular movable short-circuit solution adopted allows it to be used for medium-high powers (300 W in continuous wave radiofrequency).

Granted: 1999-05-11
Abstract: A fat depth measuring apparatus and method for use in measuring in an animal (10 ) the depth of a fat layer (14) between hide (12) and muscle (16). An ultrasonic generator (25) generates ultrasonic pul ses and an ultrasonic echo detector (25) generates echo signals (26) indicative of ultrasonic pulses received by the detector after reflection from boundaries or discontinuities (13, 15) within the tissues of the animal. Variable gain amplifier (35) amplifies the echo signals (26) and produces detector signals (38), Gain control means (40) varies the gain of the amplifier (35) to increase the probability of having exactly two detector signals (38) identifiable as arising from echoes from a hide/fat boundary (13) and a fat /muscle boundary (15). A fat depth determining means (47) receives the detector signals (38) and if they exceed primary thresho ld levels (39a, 39b) identifies the two required detector signals (38a, 38b) so as to thereby enable determination of the depth o f the fat layer (14). If more than three detector signals have levels exceeding 60 % of the threshold level (39), the dep th determination is considered invalid.

Title: Process and device for coating the surface of strip material
Inventor: FROMMANN KLAUS
IPC: C23C2/24
Filed: 1993-10-22
Granted: 2004-04-13
Abstract: The invention relates to a process and a device for coating the surface of strip material, especially non-ferrous metal and steel strip, with a metal coating, wherein the material is conducted without reversal of direction through a container holding the molten coating material, which has a passage duct below the level of the melting bath, in which induction currents are induced by an electromagnetic travelling field and produce, in interaction with the electromagnetic travelling field, an electromagnetic force for restraining the coating material. In order to achieve a killing of the melt in the passage duct as well as in the container, and in order to be able to attain, to a large extent, a counterbalance between hydrostatic and electromagnetic forces, it is proposed that a constant direct or alternating current field be directed opposite to the travelling field in the area near the container, damping the movement in the coating material. For this purpose, an additional iron core (3), which has coils (4) running parallel to the inductor coils (2) and can be subjected to direct or alternating current, is arranged above each inductor on both sides of the passage duct (5).

Abstract: A subband acoustic echo canceler for a telecommunications teleconferencing room is equipped with subband adaptive filters and filter taps associated with said subbands. A data store is provided containing a weight list for controlling allocation of the filter taps among the subbands. An optimum tap profile as determined by the weights is a composite of room acoustic impulse response and weighting adjustments based on one or more measures of perceived human acoustic sensitivity experienced by far-end users. An active periodic adjustment of the weights responsive to detection of sibilant energy in the incoming path further improves echo cancellation. Active measurement and updating of the room acoustic impulse response provides further refinement.

Abstract: An overhead cable provided with a plurality of segment strands of a sector-shaped cross-section twisted at the outermost layer and having grooves of a substantially arc-shaped cross-section at the surface at the adjoining portions of the segment strands. Also, a low sag, low wind load cable provided with tension-bearing cores comprised of strands having a linear expansion coefficient of -6 × 10 -6 to 6 × 10 -6/°C and an elastic modulus of 100 to 600 PGa and with a plurality of sector-shaped cross-section segment strands twisted around the outermost circumference of the cable including the tension-bearing cores comprised of a super-high-heat resisting aluminum alloy or extra-high heat resisting aluminum alloy, grooves of a substantially arc-shaped cross-section being provided at the surface at adjoining portions of the twisted segment strands. This enables the wind load to be reduced. Further, a low wind load cable can be easily fabricated at a low cost. In addition, by using invar strands for the cores and using segment strands of a super-high heat resisting aluminum alloy or extra-high heat resisting aluminum alloy at the outermost layer, the sag at high temperatures can be greatly suppressed. Accordingly, even the amount of the sideways swinging caused when the overhead cable is struck by a strong wind from the lateral direction can be greatly suppressed together with the low wind load construction.
