Abstract: ABSTRACT: "Information recording element having a dye-containing auxiliary layer"         The invention provides an information-recor-ding element in which information can be written and read optically. The element is constructed from a transparent substrate, a laser light-absorbing, dye-containing auxi-liary layer provided thereon, as well as a laser light-reflecting recording layer present on the auxiliary layer. Upon recording information the element is exposed to pul-sated laser light via the substrate, holes being formed in the recording layer. The auxiliary layer stimulates the formation of holes, a saving of laser light energy being obtained. In a favourable embodiment the auxiliary layer has a laser light absorption of from 20 to 80% and a maxi-mum thickness of 2500 .ANG.. In a further favourable embodi-ment the auxiliary layer also comprises an endothermal material, for example, nitrocellulose having a nitrogen content of at least 11 %.

Abstract: PARTIAL OXIDATION PROCESS WITH PRODUCTION OF POWER    (D#70,519-F) ABSTRACT        Power is developed by an expansion turbine in which the working fluid is a gaseous mixture comprising all of the hot raw gas stream leaving an unpacked partial oxidation gas generator, after removing if present a portion of the entrained solids, in admixture with a tem-perature moderating stream.  A molal increase is associated with the partial oxidation process.  Power is obtained from this molal increase in addition to the power obtained from the elevated pressure and sensible heat in the hot raw partial oxidation product gas.  The temperature moderating stream may comprise a recycle portion of the turbine exhaust gas stream after being cooled, cleaned, optionally water-gas shifted or purified, or both, and recompressed.  Alternatively, the recycle gas stream may be mixed with water, steam, or both.          In one embodiment the temperature moderating stream comprises liquid water or condensate produced in the process.    Auxiliary gas compressors for recompressing said recycle gas, and optionally for compressing a free-oxygen containing gas for use in the gas generation zone may be driven by said expansion turbine.  Similarly, an electric generator may be coupled to the turbine shaft.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure relates to cospinning and drawing polyester filaments to produce a composite yarn which develops bulk due to differential shrinkage of the filaments when heated. Filaments of ethylene terephthalate synthetic linear condensa-tion polymer are melt spun to form two separate filament bundles, a water-based spin finish is applied to the filaments of one bundle and a substantially non-volatile spin finish is applied to filaments of the other filament bundle, the filament bundles are drawn under identical treatment conditions during passage along separate paths and the filaments are then com-bined and intermingled during passage around draw rolls,  The product is a mixed-shrinkage yarn wherein the filaments treated with aqueous-based finish have a higher heat-shrinkage than the filaments treated with non-volatile finish, even though both are otherwise processed in the same manner.

Abstract: METHOD AND APPARATUS FOR REDUCING NITROUS OXIDE EMISSIONS FROM COMBUSTORS     ABSTRACT OF THE DISCLOSURE     An improved combustor for a gas turbine engine is disclosed.  Techniques for reducing the level of noxious pollutants emitted by the combustor are developed.  In one embodiment, a combination of serpentine geometried, fuel-mixing tubes discharging to the radially outward area of the combustor and an axially oriented, fuel-mixing tube near the center of the combustor are adapted to gener-ate a strong centrifugal force field within the combustor.          The force field promotes rapid mixing and combustion within the chamber to reduce both the magnitude of the combustor temperature and the period of exposure of the medium gases to that temperature.  In accordance with the method taught, the fuel air ratio in the serpentine mixing tubes is maintained within the range of .035 to .05 and the fuel air ratio in the axial mixing tube is maintained at a value less than .05.

Abstract: TITLE:  METHOD AND APPARATUS FOR COUNTING TURNS            WHEN MAKING THREADED JOINTS     ABSTRACT OF THE INVENTION    A method and apparatus are disclosed for making threaded joints, such as pipe joints, within a range of predetermined applied torque and turns values.  A pipe or a pipe and a coup-ling are threaded onto the end of a pipe string.  The applied torque is monitored and, when a reference torque value is exceeded, the number of turns are counted.  When either the actual torque or the actual turns exceeds a predetermined minimum value for that parameter and the value of the other parameter exceeds a predetermined minimum value, but is less than a predetermined maximum value, a good joint is indicated and the make-up is stopped.  A bad joint is predicted and make-up is stopped when the value of the actual torque divided by the actual turns falls outside a range of values defined by the slopes of a pair of boundary lines and predetermined minimum torque and minimum turn values.  The actual turns value is a count which is initiated the first time the actual torque value equals the reference torque value, the count being incremented when the actual torque value is greater than the reference torque value and being decremented when the actual torque value is less than the reference torque value.

Abstract: METHOD FOR FORMING DIFFUSIONS   HAVING NARROW DIMENSIONS                 Abstract A method for forming diffusions having narrow, for example, submicrometer dimensions in a silicon body which involves forming insulator regions on a silicon body, which insulator regions have sub-stantially horizontal surfaces and substantially vertical surfaces.  A layer having a desired dopant concentration is formed thereon, both on the substantially horizontal surfaces and the substantially vertical surfaces.  Reactive ion etching of the layer acts to substantially remove only the horizontal layer and provides a narrow dimensioned layer having a desired dopant concentration in the sub-stantially vertical surfaces.  Heating of the body at a suitable temperature is accomplished so as to produce the movement of the dopant into the silicon body by diffusion to form diffusions having narrow, such as submicrometer dimensions, therein.

Abstract: ABSTRACT OF THE DISCLOSURE       There is disclosed a self-propelling and steering attachment for a wheel-chair, of the type having larger diameter rear wheels and smaller diameter front swivel wheels.  The attachment can be installed and removed by the user while remaining seated in the wheel-chair. The attachment comprises a sleeve, a steering post rotatably supported by the sleeve, a ground-engaging steering and propelling wheel carried by the lower end of the steering post, a crank mechanism carried by the top end of the steering post, a power transmission connecting the crank and the steering and propelling wheel, a framework which is quickly connect-able to, and disconnectable from, the front frame portion of the wheel-chair, and a pair of superposed longitudinally-extending bars inter-connecting the framework and the sleeve.  The upper bar is rigid with the sleeve at one end and pivots relative to the framework at the other end.  The lower bar is pivotally connected to the sleeve and the framework and is extensible and retractable, being provided with a locking pin to lock this bar to a retracted, adjusted length.  For installation of the attachment, the user first rigidly connects the framework to the wheel-chair front frame portion, while the locking pin is removed, then he pushes forwardly on the crank mechanism or on the upper portion of the steering post to cause the latter to attain a more upright position, therefore causing the front swivel wheels of the wheel-chair to raise off the ground.  With this movement, the lower bar has retracted and the user then inserts the locking pin to lock the lower bar in retracted position.  The resultant assembly behaves like a tricycle, including the two larger diameter rear wheels of the wheel-chair and the front-propelling and steerable wheel of the attachment.  For removing the attachment, the user first pushes forwardly on the crank mechanism to release the lock pin, which can then be removed, whereby the front swivel wheels are lowered onto the ground, and then the framework can be removed from the wheel-chair front frame portion. The attachment may be installed on foldable or rigid wheel-chairs and on wheel-chairs of different widths.
