Abstract: In an engine, if a catalytic converter is not in the activated region, a fuel injection rate is corrected to increase, and a secondary air is introduced from a secondary air feed port into a catalytic converter. Even immediately after the cold start of the engine, the fuel injection rate is increased to be richer in fuel than the stoichiometric air/fuel ratio to feed the secondary air simultaneously, so that the temperatures of the catalytic converter and the exhaust gas can be kept over the activation temperature by the heat of the reaction of the increased fuel in the catalytic converter thereby to improve the exhaust gas purification.

Abstract: An exhaust gas purifying apparatus with a failure diagnosis function is provided. A failure diagnosis device determines that the apparats is failed when the temperature rising speed of an adsorbing device is equal to a set value or less during a gas adsorption process and if the temperature rising speed is equal to an upper limit or more or to a lower limit or less during a gas desorption process. Further, a failure diagnosis device similarly monitors the flow passing through the adsorbing device. A failure diagnosis device determines that the apparatus is failed if the concentration of discharge gas is equal to a set value or more in a discharge passage. And further, a failure diagnosis device measures the concentration of discharge gas flowing through a return passage to accumulate the amount of discharge gas in order to determine that the apparatus is failed if the accumulated value is equal to a set value or less.

Abstract: A device for determining the excessive degree of deterioration of catalyst of a catalytic converter arranged in an internal combustion engine exhaust system is disclosed. The device comprises a purification ability determining unit for determining a current purification ability of the catalyst and a temperature sensor for determining a current temperature of the catalyst. Therefore, a threshold of the purification ability which corresponds to the excessive degree of deterioration of the catalyst is determined in accordance with the current temperature of the catalyst. An appraisal value is determined in accordance with a difference between the threshold and the current purification ability. It is determined that the degree of deterioration of the catalyst is excessive when the integration value of the appraisal value exceeds a predetermined value.

The apparatus has an alternator 2 driven by the engine 1, an intake controller 3 disposed in an intake system of the engine 1, to change the quantity of intake air, a battery 8 charged by the alternator 2, the catalyst 4 disposed in an exhaust system of the engine 1 and powered by the battery 8 and alternator 2, and a regulator 7 for changing the field current of the alternator 2, to change power to be generated by the alternator 2.

Increasing the field current of the alternator 2 is delayed behind increasing the quantity of intake air.

Abstract: A method for detecting the absence of a pressure differential across a cryogenic refrigerator includes the following steps.

Within the refrigerator, a displacer is driven through a refrigeration cycle by a motor. A means for measuring the load on the motor is provided, and an electronic module monitors the load measurements to detect a loss of differential pressure across the refrigerator by comparing the load on the motor during the warmstroke to the load on the motor during the coldstroke.

Abstract: It is already known that heat insulating elements, e.g. in refrigerators, may be more efficient if they are sealingly encapsulated and subjected to a high vacuum. Based on theoretical considerations in connection with foam having small cells it has been relevant to use a vacuum of the magnitude of 0.001 mbar and hermetical sealing of the elements. According to the invention it has been found that practically well usable results are achievable at much higher pressures, viz. in a range about 1 mbar, which is much easier to produce. Consequently, a further simplification can be obtained by renouncing the hermetical sealing and relying on an only "almost tight" sealing, combined with the use of an operationally active vacuum pump provided in each apparatus unit.

Abstract: The invention shows an improvement in the lubrication of bearings and shaft seals of screw compressors for refrigerants with oils soluble in refrigerants. A typical application results, for example, for ammonia with polyalkylene glycol soluble therein. Due to the fact that a partial oil flow is taken out of the oil flow returned to the screw compressor at an intermediate pressure prior to a pressure reduction to nearly suction pressure of the compressor and conveyed via a vapor separation container, substantial proportions of the dissolved refrigerant can be fed in at an intermediate pressure connection on the compression path of the screw compressor. Correspondingly more advantageous are the lubrication properties of the remaining partial oil flow at the lubrication connection, and the disadvantages of pressure collapse or foam conveyance at an oil pump are absent, since no oil pump is required with a suitable intermediate pressure.

Abstract: A method and system acts to cool matter through the use of a carbon dioxide snow/vapor flow. The matter is supported in juxtaposition to an outlet for the carbon dioxide snow/vapor and a conductor which exhibits a reference potential state. To perform the method, a flow of liquid carbon dioxide is subjected to a pressure expansion to create a flow of carbon dioxide snow and vapor. The carbon dioxide snow and vapor then come into contact with a conductive surface and achieves a charge as a result of frictional engagement with the conductive surface. Thereafter, the carbon dioxide snow/vapor is directed towards the matter to be cooled and the conductor which exhibits a reference potential. The reference potential state attracts the carbon dioxide snow and aids in contact thereof on the matter being cooled.

Abstract: The present invention relates to a method for the production of endless tubular fabrics on a flatbed knitting machine. Two methods are described in which the tube is knitted in one case with vertical axis and in another case with horizontal axis. In the first case, tubes of any desired length can be produced. In the second case, tubes of any desired diameter can be produced. In the first method, a first half of the circumference of the tube is knitted on a front needle bed, whereupon the second half of the circumference is knitted on the rear needle bed upon the backward movement of the cam carriage of the flatbed knitting machine. Thereupon, the second course of loops is knitted on the first needle bed and knitted backward in the second needle bed. In this way an endless tube is knitted. The tube is stabilized in circumferential direction by the laying-in of a filling thread. In the other method, the first course is knitted as connected multi-layer knitted fabric on the front and rear needle beds.

Abstract: In a spin extractor, an eccentric load judging unit judges the magnitude of the eccentric load based on the amplitude of fluctuations in the motor current while a drum is rotated at a speed at which the centrifugal force on fabric articles contained in the drum is a little larger than the gravity. If the magnitude of the eccentric load detected is larger than predetermined, a balance correcting operation is conducted by a speed control unit. That is, a speed reducing position designating unit sends a pulse signal to the speed control unit at the moment when the eccentric load of the drum comes just before the highest position, in response to which the speed of the drum is reduced momentarily. When the speed is reduced, the centrifugal force is smaller than the gravity, so that the fabric articles crammed and piled fall off the inner peripheral wall of the drum. Thus the fabric articles can be scattered almost evenly.

The catalyst also provides additional oxidants in the air. The activated air is entrained in the water using an injector to thereby produce the activated water.
