Abstract: An infinitely variable steering transmission is constructed to utilize the unidirection, continuous outputs of a pair of traction drive units (12,14) for accelerating and decelerating a track-laying vehicle through a first forward and reverse propulsion range and a plurality of higher forward propulsion ranges and for developing steering power in all ranges. The transmission (10) includes a pair of interconnected output planetary gears sets (26,48) and a single input planetary gear set (32) for combining the traction drive unit outputs (16,40) and the constant speed input (27) from a suitable prime mover (8) for first and third range propulsion and steering power. Second range propulsion and steering power is obtained exclusively from the traction drive units in a manner to also provide steer cancellation, a continuous drive unit stroking pattern, and synchronous range shifting.

Abstract: The invention relates to a control device for the gas supply of the driving unit of an inclined lift, the driving unit having an internal combustion engine (petrol engine) and a hydraulic pump connected to this internal combustion engine. The essence of the invention consists in the fact that the gas supply to the internal combustion engine can be regulated as a function of the pressure built up by the hydraulic pump, in which arrangement a line preferably branches off from the pump line leading to a control valve of a consumer, which line acts on a hydraulic cylinder which in turn indirectly or directly regulates the gas supply to the internal combustion engine via a Bowden cable, a linkage or the like. <IMAGE>

Abstract: A superconductor metal matrix composite formable into an electrical current carrying material. A superconductive particulate is intermixed with a normal metal matrix, pressed into form and heated to form the composite. The metal matrix surrounds the superconductive particulate to prevent loss of oxygen from the superconductive particulate so the particulate retains its superconductive properties. The metal matrix also becomes superconductive due to proximity effect.

Abstract: A family of Phase Locked Loop circuits and methods for extraction of a clock signal from a digital data stream, for example as received by a data communication link receiver is taught. The circuits of this invention are particularly advantageous in gigabit rate links where the propagation delay of digital circuits is comparable to the duration of a bit time interval and therefore careful matching of clock extracting and data sampling circuit topology is required. In certain embodiments, a frequency detector is included making the structure suitable for use in situations where there is a large fractional difference between the incoming data rate and the free running frequency of the receiver VCO. Such is the case when both the incoming data rate and the receiver VCO frequency are not controlled by a precision element such as a crystal or a Surface Acoustic Wave device.

Abstract: A method for growing high quality epitaxial films using low pressure MOCVD that includes providing a substrate that is misoriented from a singular plane, placing the substrate into an MOCVD reactor at a total pressure of less than 0.2 atmospheres and then growing an epitaxial film on the substrate. When providing a misoriented gallium arsenide substrate, the MOCVD reactor is set at a temperature in the range of 650 to 750 degrees centigrade to grow an aluminum gallium arsenide film. This temperature is substantially lower than that at which aluminum gallium arsenide epitaxial films are commonly grown and the resulting film has a smooth surface morphology and enhanced photoluminesence properties.

Abstract: A method and apparatus for monitoring two components of an object, such as moisture content and density in a tobacco rod, using scattered electromagnetic radiation are provided. Both the real and imaginary parts of the dielectric constant of water vary greatly over frequencies in the gigahertz region while those of the remaining constituents of tobacco do not. At frequencies approaching 100 GHz, the real part of the dielectric constant of water is much closer to that of many organic polymers, such as those making up tobacco, than it is at lower frequencies. At frequencies approaching 100GHz the imaginary part is much lower than it is is in the region of 20 to 30 GHz. By comparing the scattering of electromagnetic radiation by a cigarette rod at two different frequencies and using a predetermined calibration curve based on a cigarette rod having a desired moisture content and density, one can determine the moisture content and density of the cigarette rod. If the monitoring is taking place on a cigarette making machine and the moisture content and density deviate from their desired values, the machine feeds can be adjusted automatically to restore the desired moisture content and density.
