Abstract: A fault detection circuit in a boiler-water level system includes a dual-frequency signal generator which develops two AC components with no associated DC component. The two frequencies are mixed and sent through an impedance matching circuit to match the impedance of the signal generating portion of the system with the impedance of the boiler water under measurement. The impedance-matched signal is then directed to two legs, one leg directed through one of a plurality of electrode probes and then to a first filter circuit, and the other leg is directed a second set of filters. In combination, the filters pass either the higher or the lower of the two frequencies to determine an open or short condition in the level sensing circuitry, as well as a steam vs. water condition.

Abstract: This connector comprises an elastic metal strip 4 one end of which is fixed by soldering to an element of a circuit, for example a conductive track of a printed circuit, whereas its opposite free end is applied to another element of the corresponding circuit and can be insulated therefrom by insertion of an insulating screen. Now this elastic strip (4) assumes the shape of a reclining S the ends of which each bear a bent or curved leg, one (5) of which forms the end for fixing this strip to an element (1) of the circuit, whereas the other (6) constitutes the moving contact disposed against another element (2) of the circuit. Moreover, the support (3) of the elements of the circuit has a quadrangular aperture (9) through which is fitted the first loop (7) formed by the connection strip (4), the size (e) of this aperture in the longitudinal direction being less than the maximum width (E) of the corresponding loop (7) of the connection strip. This connector can equip printed electrical circuits in order to establish or interrupt the passing of a current between certain conductive tracks of such a circuit. <IMAGE>

Abstract: A link utilization control mechanism for a demand assignment satellite communication network employs a modified point-to-point communications protocol (X.25) in order to simulate point-to-point communication ports and thereby interface what is effectively a multidrop network with point-to-point landlink communication resources. Through an acknowledgement reservation mecahsnism the return link channel is subdivided into interleaved data and (preassigned) acknowledgement time slots, in order to substantially obviate ovrhead and throughput penalties encountered in the use of large data packets to transmit reduced size acknowledgement messages. In addition, the normal contention mode of operation of the return link is augmented with a data time slot reservation mechanism through which, during periods of increased message input density at a remote station, transmission throughput is facilitated, so that congestion at the remote station is reduced.

Abstract: The ability of viruses to undergo recombination within tandemly arranged homologous sequences can be utilized to generate chimeric genes and proteins. Tandemly arranged homologous sequences will rapidly degenerate in a random fashion to yield a single copy comprised of portions of both original sequences. Therefore, a recombinant virus which contains two related but non-identical genes in tandem array yields a population of recombinant viruses which contain a spectrum of hybrid sequences derived from recombination between the original genes. The viruses, therefore, contain hybrid DNA sequences that encode proteins with new epitopes or different combinations of epitopes. Vaccines are derived which may afford protection against a broad spectrum of antigen types.

Abstract: A liquid hydrocarbon gasoline is provided by removing both the volatile and non-volatile components from C4-C12 gasoline to yield either a C6-C9 or a C6-C10 intermediate gasoline. The intermediate gasoline of this invention can be combusted in a stndard carbureted engine with less C4 and/or C5 priming than is required in standard C4-C12 gasoline, and thus provides adequate cold engine starting ability with lower Reid Vapor Pressure. The C6-C9 and C6-C10 fuel can be combusted in a modified engine without any priming by gasiying the fuel. The fuel is gasified by heating it in a chamber in the absence of air; mixing the gas with air and then combusting the mixture. The gasified fuel is advantageous because it doesn't condense into droplets and thereby is combusted more completely in the gaseous state enhancing combustion efficiency. The fuels of this invention better facilitate alcohol addition than current gasolines because of their lower Reid Vapor Pressures.

Abstract: An improved accuracy position and direction updating system for use with an automatic guided vehicle that navigates by dead reckoning. Permanent magnets providing detectable position indicators are mounted in the floor and may be at widely spaced locations such as fifty feet apart along the route of the vehicle. A row of Hall sensors is transversely mounted on the vehicle. The sensors detect the lateral location of each floor magnet relative to the vehicle as the vehicle passes over the magnet. Sensors are precalibrated, correcting for errors in sensor null voltage readings due to changes in sensor characteristics due to causes comprising aging and temperature. Data from five sensors that are closest to the magnet are correlated with a stored pattern of magnetic field and their position data are averaged to determined a first estimate of the lateral or first dimensional position of the vehicle. A running average is calculated from sequentially acquired estimates to improve the results. Such precalibration and averaging provides an improved accuracy of the lateral or first dimensional position measurement between the array of Hall sensors and the magnet. A high frequency measurement of the time at which the signals from the row of sensors reaches a peak value, which is the time that the row of sensors arrives at the magnet, provides an improved second dimensional position measurement. More than one magnet is read concurrently to provide position and bearing information during one processing cycle.
