Abstract: The invention relates to a method for mounting a fastener element (1), such as a screw or a nut, in a component (2). The fastener element (1) is provided with a deformable, cylindrical portion (3) which has an axis of symmetry. The cylindrical portion (3) is inserted in a through-hole (4) in the component (2), whereafter the cylindrical portion (3) is deformed in its longitudinal direction by means of a compressive force, so that the length of the cylindrical portion (3) is reduced. By causing the fastener element to rotate at a predetermined rotational speed so that frictional heat is generated between the contact surfaces of the fastener element (1) and the component (2), there is created a combined rivet and frictional welding joint between the fastener element (1) and the component (2). The invention also relates to a tool for mounting the fastener element in accordance with the method.

Abstract: A gas sensor (10) is shown having alternately energized infrared radiation sources (14, 16) disposed in a gas chamber (12) at different distances from an infrared detector (18). Both radiation sources are filtered at the absorbing wavelength of a gas to be monitored with one radiation source located proximate to the detector serving as a "virtual reference". The differential absorption between the two radiation sources is used to determine the concentration of a gas being monitored. In a modified sensor (30) one radiation source is seated in a parabolic recess (34a) in a base plate (34) with the radiation focused on one angled end wall (32d) of a dished shaped cover member (32) and reflected over to a second angled end wall (32e) and into the detector with the radiation sources and the detector attached directly to a circuit board (24) mounting the sensor.

Abstract: A method that detects an air-fuel ratio in each cylinder of an internal combustion engine by properly setting a cycle of detecting an element resistance of an A/F oxygen concentration sensor. Although an actual A/F signal is at the stoichiometric ratio in each cylinder at exhaust timing cycle in a practical engine rotational speed range, the ratio is largely deviated to the rich side in the #1 cylinder. The first element resistance detection timing cycle coincides with generation timing of the actual A/F signal, so that the A/F signal cannot be detected. When the element resistance detection timing cycle is preset so as to be longer than the exhaust timing cycle, the second actual A/F signal detection timing for the #1 cylinder does not coincide with the element resistance detection timing. Consequently, the actual A/F signal of the #1 cylinder can be detected as an A/F signal by the A/F sensor.

Abstract: The semi-permeable characteristics of polymeric liners may be used to characterize defects, if present, in loose liners contained inside piping and equipment. The use of polymer-lined equipment is common in the chemical, refining and other industries where the polymeric liner offers excellent chemical resistance and the outer shell gives the required strength and rigidity. Permeability characteristics of liners are investigated with particular reference to volatile process gasses and/or process-soluble tracer gasses. The resulting data are used to establish nondestructive testing techniques for evaluating the integrity of lined equipment during normal operation where a mass spectrometer equipped with a sampling probe is used as the sampling and sensing devices. Real-time data is compared to characteristic data, obtained under laboratory conditions, on a membrane of the polymer from which the liners are made. Acceptance or rejection of the equipment is determined by such comparison.

Abstract: The electrical conductivity of laundry in a laundry drum is measured and the moisture content is determined from the measured quantity. A polarization voltage, which corrupts the measurement result, is formed at the electrodes. In order to compensate for this disturbing influence, as well as for other material and aging effects, the conductivity measurement is briefly interrupted and the polarization voltage which is present across the electrodes and has formed during the conductivity measurement is measured. The measured error voltage is used to compensate the laundry voltage measured during the previous conductivity measurement. This improves the determination of the conductivity, and thus of the moisture content, considerably. The method is particularly suitable for a microcontroller.

Abstract: A running quality evaluator for an internal combustion engine for optimizing the running quality of the engine. The running quality evaluator includes an engine speed circuit which conditions a series of trigger pulses from the engine. The conditioned trigger pulses from the engine speed circuit are converted by an integrating circuit into an engine speed signal. The engine speed signal increases as the frequency of the trigger pulses from the internal combustion engine increase. Thus, the engine speed signal changes as the frequency of the trigger pulses from the engine change. The engine speed signal from the integrating circuit is then converted into an engine quality signal by a differentiating circuit. The engine quality signal increases as the rate of change of the engine speed signal increases. The engine quality signal from the differentiating circuit is then integrated into an output signal by an output circuit.

Abstract: An atmospheric water vapor sensing system uses Global Positioning Satellites (GPS) to determine the refractivity and Slant-path Water Vapor Delay (SWD) between an Earth-based GPS receiver and a plurality of satellite-based GPS transmitters. The system provides improved precision in position calculation measurements by eliminating the refractivity effects of water vapor.

The system is especially useful in monitoring the Earth's crustal deformation.

All of the customization required for a particular device can be confined to the adapter, and thus the reset of the fixture can be made generic.
