Inventor: ROSS GERALD FRED
IPC: G01S13/18
Filed: 1987-03-03
Abstract: A baseband receiver with a range gate interval in the order of nanoseconds. A tunnel diode (32), set to the low level state, is coupled across the output terminals of a bridge that is balanced in the absence of a received signal, during the range gate interval. Signals received by an antenna (31) are coupled to a further tunnel diode (17) in an arm of the bridge causing it to change from its low level state to its high level state, thereby unbalancing the bridge and establishing a voltage at the output terminals of the bridge that fires the tunnel diode (32) coupled thereacross.

Title: Composition and method for slowly dissolving siliceous material.
Inventor: BLUMER DAVID JAMES
IPC: E21B43/27
Filed: 1987-06-18
Abstract: PCT No. PCT/US87/01462 Sec. 371 Date Feb. 22, 1988 Sec. 102(e) Date Feb. 22, 1988 PCT Filed Jun. 18, 1987 PCT Pub. No. WO88/00278 PCT Pub. Date Jan. 14, 1988.An acidizing composition and method for slowly dissolving siliceous material by the slow production of very low concentrations of hydrofluoric acid is provided by this invention. The continual generation of very low concentrations of hydrofluoric acid is accomplished by the hydrolysis of hexafluorotitanate-containing compounds. The acidizing composition is particularly useful and advantageous for the solubilization of siliceous clay in or adjacent the pores of subterranean hydrocarbon formations thereby increasing the permeability of said formations. Because of the very low concentration of hydrofluoric acid in the acidizing composition solubilization of siliceous clay deposits is possible at relatively large distances from the point of injection into the formation, for acidizing formations which are too sensitive for more reactive acidizing compositions, for acidizing formations containing chlorite clays, and/or for acidizing formations having an elevated temperature including formation temperatures of 125 DEG  C. or higher.

Filed: 1988-03-31
Abstract: In the pulse density D/A or A/D conversion, an improved averaging of a PDM signal (pm) in a jittering clock signal (cl) is achieved by the fact that the PDM signal (pm) is supplied to the series input (zs) of an n-stage shift register (sr), the parallel output (z1, ...zn) of which is used for controlling n state signals (i4....;ii'....; i8....; i8d), the shift register (sr) being switched by the clock signal (cl). The n state signals are combined to form a sum signal (i4s; i6s; i8s; si, siq) which feeds a low-pass filter (tp). Particularly advantageous developments are obtained if the n state signals are weighted and/or isolated from the respective preceding and subsequent state in time by means of gate circuits (g; g, gs).

Abstract: For the removal or suppression of ice on rotating regenerative heat- and/or matter-exchangers, a part flow of a pure gas, preferably of one of the heat-exchanging gas flows, is guided, with an increase in temperature and pressure, partially through the storage mass (4, 24, 34) and/or through the annular chamber and subsequently through the gap between the circumferential sealing and the storage mass (4, 24, 34). The regenerative heat- and/or matter exchanger used in this respect is characterised by a connection or bypass (42) to one of the ducts (2, 12) of the heat-exchanging gas flows, a heat source (8, 28, 38) arranged therein, and at least one regulating member (60) in the energy supply line of the same, and also by gas connection pipe pieces of the housing, which surrounds the storage mass (4, 24, 34), for a further sector between those of the heat- and/or matter-exchanging gases. <IMAGE>

Abstract: In flue gases or other humid exhaust gases which are relatively cold and contain SO2, NO2 and other gaseous pollutants, the SO2 content is oxidized to SO3 and the NO content is reduced by a catalytic treatment, the SO3 content is condensed as sulfuric acid and other gaseous pollutants are removed by being scrubbed with aqueous liquids at low temperatures. In order to heat up the flue gas to the temperature required for the catalysis, the flue gas is heated up in a first heating-up stage by an indirect heat exchange with the catalytically treated gas before the catalytic treatment, the heated-up gas is heated up further in a second heating-up stage to the temperature required for the catalytic treatment, the catalytically treated gas which has been cooled in the first heating-up stage is cooled further in an indirect heat exchanger below the dew point temperature of sulfuric acid and is subsequently fed to an SO3 condenser. The remaining sulfuric acid vapor is absorbed by sprayed dilute sulfuric acid to form a dilute sulfuric acid having a predetermined concentration, the gas leaving the SO3 condenser is scrubbed in a scrubber with a sprayed aqueous liquid and is thus cooled to 40 DEG  to 60 DEG  C. and the purified gas is reheated to the required chimney inlet temperature.

Abstract: A reciprocating piston type refrigerant compressor includes a housing (20) having a cylinder block (201) provided with a plurality of cylinders (30) and a crank chamber (23). A piston (31) slides within each cylinder and is reciprocated by a drive mechanism which includes a rotary drive shaft (22), a rotor (25) mounted on the drive shaft, and a coupling mechanism which converts the rotary motion of the rotor into the reciprocating motion of the pistons. The coupling mechanism includes an inclined member (26) which has an inclined surface disposed at an adjustable angle of inclination. Accordingly, the stroke of the pistons within the cylinders can be changed by adjusting the angle of the inclined surface in response to the change of pressure in the crank chamber. A spring (37) applies a force to urge the inclined surface to a decreased angle when the angle is greater than a predetermined angle, but applies no force when the angle is less than the predetermined angle.

Abstract: A series controller in which a plurality of node controllers are connected in series for a main controller to directly control a vatiety of sensors and actuators. The main controller intensively controls the sensor data or the actuator control data indirectly through a signal sequence delivered through the node controllers. In each node controller, furthermore, the data are transferred between the signal sequence and the sensors or the actuators that are to be controlled. An error code is added to the signal sequence to be transferred to the next port based upon the logical sum of the two conditions which are: whether there is an error confirmed by inspecting the error check code added in advance to the signal sequence to check the occurrence of an error among the node controllers, and whether an error code is added to the signal sequence to inform the occurrence of error.
