Abstract: METHOD AND APPARATUS FOR COMBUSTION OF DIVERSE MATERIALS AND HEAT UTILIZATION     ABSTRACT OF THE DISCLOSURE     A method and apparatus is disclosed for combustion of diverse materials, particularly combustible solids, liquids or gases, and mixtures thereof.  Organic waste materials or hydrocarbon-containing materials such as sewage sludge, refuse, coal, refinery sludge, tar sands, coal shale, coal tailings, spent foundry sand, and many other materials, may be inciner-ated.  A rotary combustion apparatus is employed which consists of a cylindrical drum, or other similar regularly shaped chamber, with a substantially horizontal axis of rotation.  In one form the apparatus has a series of internal zones including an ignition zone, a principal combustion zone, a falling temperature zone and a spent solids removal zone.  The appa-ratus further includes solids transport chutes for forward and backward circulation of solids, arranged for the transfer of solids to or from one or more points.  Particulate combustible solids gases or liquids feedstock may also be heated by re-cycled hot solids material to preheat, condition or otherwise treat the feedstock.  The method and apparatus employs direct solids-to-gas contact established by lifting and cascading combustible solids through a hot gas stream such that high combustion efficiency, rapid throughput, low pressure drop across the combustion zone, among other advantages, are ob-tained.  In particular, the method and apparatus is especially suitable for burning coal and utilization of the by-product heat of combustion for generating steam.  Incineration of refinery sludge, spent foundry sand and oily mill scale are also disclosed and all processes provide environmental advan-tages.

Abstract: ABSTRACT            A first aspect of the invention is concerned with fuels and particularly jet and diesel fuels which comprise blends of substituted mono cyclohexane material and two ring non-fused cycloalkane material.  The first material may be n-propylcyclohexane or n-butylcyclohexane. The second material may be nuclear substituted bicyclohexyl and may include cyclohexylbenzene.  A second aspect of the invention concerns producing constituents for the fuel from heavy aromatic materials by breaking down the heavy aromatics to naphthas, separating light naphthas and other constituents of the fuel before reforming a heavy naphtha fraction to provide a BTX fraction which may be treated by hydroalkylation or pyrolysis to provide two ring non-fused cycloalkanes.  The product may be enriched by hydrogenation.

Abstract: Abstract A method for producing an optical fiber preform comprises jetting a glass raw material mixture containing at least one phosphorous compound and a fuel gas through a burner, hydrolyzing the raw materials in the flame to form fine glass particles, depositing the fine glass particles to form a porous glass preform and then sintering the porous glass preform in a stream of an inert gas to remove phosphorous liberated from the preform to produce a trans-parent optical fiber preform.  From this transparent optical fiber preform, an optical fiber having low attenuation at a wavelength of about 1.52 micrometer can be produced.

Abstract: Abstract of the Invention A cellular mobile radio-telephone system incorpor-ates hand-off equipment for effecting a hand off of communication links coupled to a mobile subscriber transceiver as the trans-ceiver travels from one cell to an adjoining cell.  The hand-off equipment includes a filter which smooths voice channel signals received from the mobile transceivers so as to permit a more precise determination as to when a reduction in signal amplitude indicates the need for a hand-off.  The operation of the filter includes long and short term averaging of a sequence of signal samples.  Circuitry is also provided for predicting a time of signal fade-out based on differences in the amplitude of successive samples or groups of samples.  Also disclosed is circuitry for commanding a change in transmitter gain in a transceiver as a function of signal fade-out.

Abstract: ROLLING ELEMENT BEARING MEMBER          ABSTRACT A rolling element bearing member designed for use in a preselected bearing operation, such as a gas turbine engine, which develops a predetermined operating hoop tensile stress in the member includes a hardened layer contiguous with a ductile core having a hardness less than 50 Rockwell C.  For example, the hardened layer is a carburized layer of high hardness in the range of 58-66 Rockwell C.  The hardened layer has improved resistance to crack initiation and propagation as a result of providing the layer with compressive residual stress in an amount greater than the predetermined operating hoop tensile stress, for example in the range of about 10-60 ksi to a depth up to about 0.06 inch.  Such a member is made by providing a member of a metal alloy having the capability of developing such a hardened layer, and then processing the member to develop the layer in the amount of compression.

Abstract: INTELLIGENT PHASE-LOCKED LOOP  Abstract of the Disclosure An   intelligent   phase-locked   loop   performs adaptive  transfer  function  parameter  selection  and fault tolerant self-monitoring within the phase error filtering algorithm.  The algorithm includes a capture mode, at least one align mode and an operate mode. The capture mode shifts to the align mode if the phase error limit is not exceeded at the end of a first period of time.  The align mode switches back to the capture mode if a reverse phase error relation is met during the mode.  At the end of the align mode, the algorithm switches to the operate mode if a forward phase  error  relation  is  met.   The  operate  mode continues indefinitely.  However, a switchback to the align mode is made if an out of lock phase error limit is exceeded for the operate mode.  The bandwidths of the transfer function of the loop are adapted for each of the modes so that the capture mode is the broadest bandwidth, the align mode is an intermediate bandwidth and the operate mode is a narrow bandwidth.  Further, according to the  invention,  the algorithm performs hardware  fault  monitoring  based  on   statistical processing  carried  out  during  the  phase  error filtering cycle.
