Abstract: In a method of liquefying a permanent gas, such as nitrogen, refrigeration is provided for the permanent gas by one or more working fluid cycles 81 and 89 in which work expanded working fluid is brought into heat exchange relationship with the permanent gas stream at temperatures above the critical temperature of the permanent gas, and a working fluid cycle 77 in which work expanded working fluid is brought into heat exchange relationship with the permanent gas stream at a temperature below the critical temperature of the permanent gas. The outlet pressure of the turbine 78 is at least 10 atmopsheres and preferably from 12 to 20 atmospheres. By selecting such a high outlet pressure for the turbine 78 and for the turbine of any other working fluid cycle operating at below the critical temperature of the permanent gas, the thermodynamic efficiency of such working fluid cycles may be increased by virtue of the relatively high specific heat that the working fluid has at such pressure.

Abstract: A level measuring sensor is arranged at the start of the straining zone in the perforated belt press and this in particular measures the level change and then regulates the flocculant inflow. In order that the level in the straining zone is stabilized, the perforated belt press must operate in the overflocculation zone. If the flocculant inflow is reduced to the technically possible operating limit, the dry substance content of the filter cake has an optimum value. Thus, the optimization of the control of the operation of the perforated belt press can be reduced to a relatively simple measurement of a level or the time changed thereto.

Abstract: An electric motor brush or other electrical contact fabricated with intercalated graphite exhibits improved electrical conductivity, strength and performance when compared with electrical brushes made with non-intercalated graphite or with carbon. Such contacts may be formed by filling a mold of the appropriate shape with intercalated graphite powder and applying sufficient pressure and heat to produce a coherent mass. The ability of intercalated graphite powder to be compacted in such a fashion leads to economic methods of manufacturing electrical contacts. The properties of these contacts may be further improved by the incorporation of metal powder, organic polymers or ceramic powders into the intercalated graphite prior to pressing.

Abstract: To precisely detect the position of a mechanically moving portion which is driven by a motor, restraining the effect of backlash. A position detector (3) produces a position detection pulse every time after a mechanically moving portion (2) driven by a motor (1) is moved by a predetermined amount. A counting means (4) counts the position detection pulses sent from the position detector (3), and a reading means (5) reads a value counted by the counting means (4) every time after a predetermined period of time. A cancelling means (6) cancels the content of the counting means (4) by a counted amount read by the reading means (5). A backlash amount storage means (7) stores a backlash amount of the drive system, and a moving amount calculating means (8) calculates a practica l amount of movement of the mechanically moving portion (2) every time after said predetermined period of time based upon the content stored in the backlash amount storage means (7) and the value read by the reading means (5). An integrating means (9) integrates the results calculated by the moving amount calculating means (8).

Abstract: A magnetometer for detecting variations in a DC magnetic field. The magnetometer includes a magnetic field variation sensitive device that resonates at a characteristic resonant frequency by converting energy stored therein as a result of being excited by electromagnetic radiation at twice the resonant frequency when biased by a DC magnetic bias field within a predetermined field intensity range, in which the amplitude of the resonance varies with variations of the field intensity. The magnetometer further includes an excitation circuit (12, 14, R1, L1, C1) for exciting the device to resonate at the characteristic resonant frequency at an amplitude level that remains constant when the DC field intensity does not vary within the predetermined field intensity range; a DC voltage source (16) within the excitation circuit for biasing the device within the predetermined field intensity range; and a sensing instrument (18, 20) for sensing the amplitude of the resonance of the device at the characteristic resonant frequency. A variation in the amplitude of the resonance sensed by the sensing instrument indicates a variation in the intensity of the DC magnetic bias field. The magnetometer is utilized in a variety of different systems, including a system for actuating an output instrument, such as a traffic signal controller, in response to a predetermined threshold variation in a DC magnetic bias field, such as occurs when a motor vehicle moves into the vicinity of the magnetometer; a system for probing for materials whose presence affects the intensity of a DC magnetic bias field, such as buried pipes for ferromagnetic mineral deposits; a system for communicating in the low frequency range of the electromagnetic spectrum; and a system for guiding a probe with respect to the location of an object whose presence causes a variation in the intensity of a magnetic bias field.

Abstract: A vehicle has mounted inside the upper end of a suspension tower of its wheel suspension system, a support assembly for holding the upper end of a macpherson strut. The assembly has an inner bearing (32) supported in a resilient rubber bush (18). The axis of the bearing is arranged eccentrically to the centre of one, or preferably two pairs of overlapping rings (21,22 and 33,100). Each pair of rings can be clamped against rotation, or freed to allow one of the rings to be rotated with respect to the other. Rotation of the unclamped ring produces a repositioning of the upper end of the strut so that its misalignment in camber and cator can be corrected. The two rings can then be re-clamped together.

Abstract: Method and apparatus are disclosed which reduce the variable length body of alert information to a standard 32-bit number which indexes the lengthy, variable length information. To the 32-bit number there is concatenated a product identification code which reduces the likelihood of inadvertent duplication of the 32-bit number by two different alert sending entities to an acceptable level. Reduction of the alert record to a 32-bit number plus the product identification code enables alert recognition and filtering to be conducted at the host/system network operator's console for logging, displaying the alert to specified operators, selective display, inhibition of these or forwarding of the alert to an additional operator or use of the alert as a triggering signal for the display of specific informational screens for the operator. Useless alerts in a particular environment may be discarded altogether and recognized prior to displaying them to the operator.
