Date Jul. 25, 1991.A method of utilizing the high energy values of fossile fuels in central heating boiler systems. The boiler system comprises a processor which includes an air heat pump (5) which functions to cool the system flue gases by condensation. A first fan (10) generates a first circulation (C1) of boiler room air, via the air heat pump (5), this circulation of air also passing through a heat exchanger (4) where heat exchange takes place with the flue gases. A second air circulation (C2) is generated with the aid of a flue-gas fan (7) which removes flue gases from the boiler by suction, thereby generating a subpressure in the boiler room so that fresh air will be drawn in from the ambient surroundings, this air passing through the heat exchanger (4). A lower pressure is maintained on that side of the heat exchanger (4) on which the air/flue gas mixture (C2) flows into the heat exchanger, whereas a higher pressure is maintained on the other side of the heat exchanger (4) on which the air/flue gas mixture (C 2) flows into the heat exchanger (4) on which the cooling boiler-room air circulates (C1). This will ensure that flue gases will always flow out to the free atmosphere, via the heat exchanger (4). The exhaust air/flue gas mixture is caused to pass a cooling device (21) and thereby pre-cooled prior to passing through the heat exchanger in said second circulation.

Abstract: In a broadcasting system with time division multiplexing of digital signals containing a synchronization pattern and analog signals, sync extraction is achieved with a process including detecting the extreme values of the signals to be subjected to decoding, after they have been amplified with a gain G, with a time constant compatible with the low cut off frequencies to be accomodated; the gain G is controlled as a decreasing function of the difference between the extreme values with a time constant greater by several orders of size than the repetition period of the multiplex; before decoding and determination of the extreme values, there is added to the amplified signal a DC component which is a decreasing function of the sum of the extreme values, until the retrieval of the clock signal and identification of the synchronization pattern downstream of the coding.

Abstract: Lignin is precipitated in high yields and at high rates from a black liquor produced by pulping wood at high temperatures and pressures with an aqueous lower aliphatic alcohol solvent. The lignin is precipitated by diluting the black liquor with water and an acid to form a solution with a pH of less than 3, an alcohol content of less than 30% by volume and a temperature of less than 75 DEG C. The precipitated lignin, when subsequently dried, is in the form of a powder which requires little or no crushing to convert it into a fine uniform size suitable for use without further significant processing.

Abstract: The bogie for track vehicles, which is used for at least one body, comprises at least two axle sets. Each axle set (2, 2') is arranged in its own support frame (3, 3'). The support frames (3, 3') are connected to one another by spring bodies (5). The support frames (3, 3') are symmetrical and can pivot mutually by means of a vertical bearing (7). The spring bodies (5) have a primary shock-absorbing effect. The support frames have the shape of symmetrically-arranged U-shaped half-frames (3, 3') and rest on one another in a flexible manner by means of their projecting arms (4, 4'). On bends, there is consequently no movement in relation to the axle sets (2, 2'). The design, which is essentially identical for motor-equipped and non-motor equipped bogies, can be adapted for any selected bogie arrangement. When small-diameter wheels are used, the vehicle floor can be kept very low, facilitating the boarding and alighting of passengers, and ensuring a high level of directional stability.

Title: Method of monitoring the drilling of a borehole
Inventor: BOOER ANTHONY
IPC: E21B47/00
Filed: 1990-07-11
Granted: 2001-12-25
Abstract: The invention relates to a method of monitoring the drilling of a borehole through an earth formation with a rotating drill bit fixed at the lower end of a drillstring. At least one physical quantity associated with the vibrations resulting from the interaction of the rotating drill bit with the earth formation is detected and an oscillatory signal is generated in response thereto. Filter coefficients ak of an auto-regressive filter model are determined by fitting the filter output signal with the oscillatory signal. The reflection coefficients of the vibrations propagating along the drill string and being reflected by a mis-match of impedance of two successive elements of the system earth formation/drillstring are derived from the filter coefficients. Finally, the hardness of the formation being drilled, the contact of the drillstring with the borehole and the vibration level of the vibration along the drillstring are determined from the reflection coefficients.
