Abstract: A method for removing particulates from a gas is described incorporating an electrostatic precipitator and a barrier filter in series, i.e. baghouse, downstream of the electrostatic precipitator. The series arrangement enables the barrier filter to operate at significantly higher filtration velocities than normal 4.06-20.32 cm/s (8-40 ft/min) versus 0.76-2.54 cm/s (1.5-5 ft/min) and reduces the size of the barrier filter significantly. The invention overcomes the problem of the sensitivity of electrostatic precipitator particulate collection efficiency to variations in particulate and flue gas properties and the alternative of having to substitute the electrostatic precipitator with large barrier filters in which its use would be prohibited by cost and space considerations.

Abstract: A combination electric motor and transmission unit device has two inputs and a rotational mechanical output, at least one of the inputs being of electrical power, to a corresponding integral combination of an electric motor means with a transmission means. The directions of rotation and the rotational speeds of the two inputs can be controlled to provide the mechanical output at any desired rotational speed with peak power output, depending on the controls, thus providing an ideal infinite speed device. The device employs a novel arrangement of a differential unit or a planetary gear unit. The combined motor and transmission device is lightweight, requires a small number of moving parts, and is useful in vehicles powered by electricity, including for regenerative braking. Another embodiment of the drive device is useful for a flywheel for peak power supplementation and also regeneration.

Abstract: In Multistation Demand Assigned Time Division Multiple Access Systems digital information is communicated from a head end to a population of oustations so that all the outstations receive the same stream of digital information and select their traffic from it. Traffic is only sent to and from an outstation when there is a demand for it. As the outstations are at random ranges from the head end it is necessary to know the time of travel for a burst of information so they arrive at the head end sequentially. The traffic dependent free time is consolidated and made available for ranging-in outstations.

The control arrangement comprises a comparator circuit 3 that compares a fraction of the voltage across the switch 1 with a reference voltage, for example supplied by a Zener diode or bandgap diode, and opens the switch if the fraction is greater than the reference voltage. The comparator circuit is powered by the voltage drop in the line across the switch so that the arrangement can be formed as a two-terminal device that requires no external power source. The arrangement has the advantage that it exhibits a relatively small variation in performance with respect to temperature variations.

Abstract: Two methods are provided for applying and forming a protective composite coating on a metallic substrate. In the first method, the substrate is heated to a temperature between about 175 DEG  C and 275 DEG  C and a powdered coating of epoxy resin between 100 and 400 microns thick is applied to the outer surface of the heated substrate. A premixed powder coating of epoxy resin and polyolefin is applied directly onto the epoxy resin coating, forming an interlayer of interspersed domains of epoxy and polyolefin between about 100 and 400 microns in thickness. On to this, powdered polyolefin is sprayed to produce a polyolefin sheath coating for the metallic substrate between 200 and 1000 microns in thickness. In the second embodiment of the method, the interlayer is formed by spraying pure epoxy resin powder and polyolefin powder from separate sources simultaneously onto the substrate. By these methods, a metallic substrate coated with a composite epoxy/polyolefin protective coating is produced. A particular advantage of the methods results from the fact that the powders are applied in a common spray booth through which the substrate is advanced. <IMAGE>
