Abstract: ABSTRACT           A sootblower of the long retracting variety including a drive system which simultaneously rotates the lance tube as it is inserted and withdrawn from the boiler.   A variable speed drive is employed to modulate the rotational speed of the lance tube in accordance with the projected distance of the lance tube such that the lance tube is driven faster at intermediate lance tube projected distances thereby optimizing the cycle time of the sootblower.  The modulated rotational speed of the lance tube is maintained at all projected distances below the critical speed which varies as a function of projected distance and the sootblower type.   By driving the lance tube at certain projected distances at a rotational speed above the critical speed for other projected distances, the translational speed is increased and cycle time reductions are realized as compared with the prior art wherein the lance tube is driven at a constant speed below the minimum critical speed.          The lance tube speed may be varied upon retraction and operated at constant speed for insertion or vice-versa or the speed may be varied both on insertion and retraction, as the cleaning requirements of a particular application requires.

Abstract: ABSTRACT OF THE DISCLOSURE             SYSTEM FOR DETERMINING THE FREE POINT OF PIPE STUCK IN A BOREHOLE  A system for determining the stuck point of pipe in a borehole including a wireline tool having an exciter coil and a receiver coil axially spaced from one another.  The exciter coil is driven at a preselected low frequency and the voltage induced into the receiver coil is related to the magnetic permeability of a pipe through which the tool is run.  A receiver coil voltage log is run of the sec-tion of pipe in the region of the stuck point first while that region is substantially free of mechanical stress.  A second log of the same region is run with the pipe under mechanical stress.  Comparison of the two logs determines the stuck point from the difference in magnetic permeability of the stressed pipe above the stuck point and the unstressed pipe below the stuck point.

Abstract: SEMICONDUCTOR-ON-INSULATOR (SOI) DEVICES       AND SOI IC FABRICATION METHOD          Abstract A new SOI device which permits both the kink effect to be avoided and  threshold voltage to be regulated, as well as a new method for fabricating SOI ICs, is disclosed. The new device includes an  electrically conductive pathway extending from the active volume  and terminating in a non-active region of the substrate of the device.  A back-gate bias is communicated to, and kink-inducing charges are conducted away from, the active volume through the conductive pathway.          The new fabrication method permits SOI ICs to be fabricated using available circuit designs and pattern delineating apparatus, e.g., IC mask sets.  This method involves the formation of a precursor substrate surface which includes islands of insulating material, each of which is encircled by a crystallization seeding area of substantially single crystal semiconductor material.  The boundaries of the islands are defined with a first pattern delineating device, e.g., a mask, which, in terms of the pattern it produces, is substantially identical to a second pattern delineating device.  The latter device is a component of pattern delineating apparatus used in forming an IC, e.g., an IC mask set, the component being used to delineate the device regions of the IC.  A layer of non-single crystal semiconductor material is formed on the precursor substrate surface, and crystallized with little or no displacement of the islands.  The pattern delineating apparatus is then used to form an IC in the crystallized material.

Abstract: ABSTRACT      A stereophonic broadcasting system incorporat-ing companding of the difference signal in which both the usual difference signal and a compressed version of the difference signal are transmitted to one or more remote receivers.   At the receiver the usual difference signal and the compressed difference sig-nal are combined and the resulting signal then ex-panded to obtain a noise-reduced difference signal for matrixing with the sum signal to obtain the orig-inal left and right signals.   Utilizing both differ-ence signals increases the effective level of the re-ceived difference signal by 6dB, whereas the noise is increased only 3dB, for a net improvement of 3dB in signal-to-noise ratio.   Utilization of both differ-ence signals at the receiver also permits compression of  the difference  signal  according  to any desired compression law.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of generating a low-tar generator gas includes contacting the hot tar-containing generator gas in a contact zone with ballast bodies to cool the generator gas and capture tar and dust on the exposed surfaces of the ballast bodies, and admixing the thus heated ballast bodies to the wet solid fuel to be gasified to dry and pre-heat such fuel in preparation for the actual gasification which is performed in two separate gasification zones which are arranged one above the other by reacting the solid fuel with an oxygen-containing gasification medium that is introduced from above into the upper one, and from below into the lower one, of the gasification zones with attendant formation of two conflagration fronts in the gasification zones.          The generator gas which is thus generated in the two gasification zones is discharged through a common discharge conduit which has the contact zone incorporated therein. An arrangement for perform-ing this method includes a contact apparatus which bounds the con-tact zone, is incorporated in the discharge conduit and contains a bed of the ballast bodies, the bed being replenished by ballast bodies which have been separated from ashes after they have been discharged from the lower one of the gasification zones.

Abstract: ABSTRACT    The presence and concentration of a light absorbing constituent in a fluid medium is determined in-situ by immersing in such medium a probe having a prism at one end whose refractive index is greater than that of the medium and causing light including a wavelength absorbable by such constituent to traverse an optical path through the prism and undergo successive attenuated total reflec-tions.  At each reflection some of the light will be absorbed by the constituent.  The intensity of light emerging from the prism is measured at one or more wavelengths, including one absorbable by such constituent.  The concentration of the constituent is determined by comparison of the measured intensity with values obtained from like measurements performed on like mediums containing known concentrations of the constituent.

Granted: 1989-09-26
Abstract: ABSTRACT OF THE DISCLOSURE     A method of producing a composite elastic material comprises stretching an elastic web to elongate it,  for example, elongating a nonwoven web of meltblown elastomeric fibers,  and bonding  the  elongated web  to  at  least  one gatherable  web,  such  as  a  spunbonded  polyester  fiber material, under conditions which soften at least a portion of the elastic web to form the bonded composite web of elastic  material.   The  composite  material  is  relaxed immediately after the bonding to prevent the elastic web from  losing  its  ability to contract  from the  stretched dimensions which it assumed during the bonding step.  Such immediate relaxation of the composite material after the bonding step results in the the elastic web retaining its ability  to  contract  so  that,  upon  termination  of  the elongating force, the elastic web contracts to form gathers in the gatherable web.  The bonding may be effectuated by pattern embossing overlaid elastic and gatherable webs with at least portions of the elastic web heated to at least its softening  temperature.   The  resultant  composite  elastic material comprises a coherent elastic web which is bonded to  at  least  one  coherent  gatherable  web  whereby  the gatherable  web  is  extensible  and  contractible  with  the elastic web upon stretching and relaxing of the composite material.

Abstract: ABSTRACT     The invention relates to an optical relay com-prising a target of an electrically insulating material, and transmitting light in  dependence on the electric field parallel to the direction of propagation of the light, means for scanning a first face of the target by means of an electron beam, an anode which collects the secondary electrons emitted by the beam, an optically transparent and electrically conducting plate arranged at the second face of the target, the target receiving the electric video information signal, thereby forming a control electrode, the target being constituted of a material which becomes ferroelectric below a certain temperature, called the Curie temperature in the proxi-mity of which the optical relay operates.  The target is characterized in that, in order to keep the target at the required operating temperature the optical relay is provided with a heat exchanger which acts on the target, such that in normal operation the target is formed of a useful central area where the target exhibits a single domain ferroelectric phase and a neutral peripheral area at a temperature which is higher than the Curie tempera-ture, where the target exhibits a paraelectric phase.          The optical relay is used for the production of televi-sion pictures on a  large screen.
