Abstract: ABSTRACT     A system and method are provided for continually preventing filament bridging between adjacent draw nozzles.          The system comprises a heating element, generally in the form of a metal heating wire, which is disposed between adjacent nozzles and is positioned in the path of filaments attempting to bridge the nozzles.  The temperature is maintained at a level high enough above the melting point of the filaments so that they will continuously and instantaneously melt when they contact the heating element.

Abstract: Abstract of the Disclosure Derivatives of the newly discovered microorganism Thermoanaerobacter ethanolicus which under anaerobic and thermophilic conditions continuously ferment substrates such as starch, cellobiose, glucose, xylose and other sugars to produce recoverable amounts of ethanol solving the problem of fermentations yielding low concentrations of ethanol using the parent strain of the microorganism Thermoanaerobacter ethanolicus are disclosed.  These new derivatives are ethanol tolerant up to 10% (v/v) ethanol during fermentation.  The process includes the use of an aqueous fermentation medium, containing the substrate at a substrate concentration greater than 1% (w/v).

Abstract: ABSTRACT OF THE DISCLOSURE         An optical fiber disposed between a light source and a photodetector is subjected at a number of points, equi-spaced along its axis, to a transverse pressure causing a significant attenuation of the transmitted luminous radi-ation.  The optimum spacing of the pressure points is a function of the radius of the fiber core and of the refrac-tive indices of its core and its envelope.  These pressure points are formed by turns of a substantially incompressible helix which is wound around the fiber and which may be con-stituted by an internal or external rib of a surrounding flexible sheath of similarly incompressible material,  The pressure may be applied by a piezoelectrical transducer and may be modulated by an electrical signal to be picked up by the photodetector.

Abstract: Title: High-Speed Milling Cutter ABSTRACT OF THE INVENTION    A milling cutterhead provided with slots for receiving indexable, disc-shaped cutting bits mounted in individual nest plates.  The cutterhead is a generally cylindrical body comprising two concentric body parts, namely, a main member having a circumferential rim portion and an interior ring member which mates with and fits tightly within that rim portion.  The nest-receiving slots are cut through the full radial width of the rim portion, and the outer circumference of the interior ring forms the inner walls of the slots.  Each nest plate supports more than one-half the circumference of its respective indexable bit at three or more spaced locations so that any inserted bit, no matter how indexed, will have either its radial or axial diameter substantially aligned in a predetermined plane, thereby assuring that the cutting edge of each indexable disc-shaped bit will be positioned to an axial or radial accuracy equal to or less than one-half the diametral tolerance for such disc-shaped bits.  With such assured accuracy, no further truing of the individual bits is required when they are indexed. Further, the interior ring design of the cutterhead reduces the probability of stress-related failures and provides increased rigidity needed for high-speeding cutting, and separate tightening wedges permit cutting discs to be readily indexed and/or changed without disturbing the nest plates and without necessitating further truing of such indexed or newly-inserted bits.                 .

Abstract: ABSTRACT     A new and improved resonant free-piston Stirling engine and method of operation employing a novel virtual rod displacer is described.  The engine has a reciprocal movable displacer that is exposed to a working gas pres-sure wave periodically produced within the  Stirling engine to drive a working member (power piston) from which work is derived by the engine.  A rod is secured to and reciprocally moves with the displacer within the Stirling engine and has a rod piston area formed on the end of the rod remote from the displacer with the rod piston area also being subjected to the working gas periodic pressure wave.  Suitable support bearings are designed within the Stirling engine housing for reciprocatingly supporting the displacer and rod assembly within the Stirling engine with a set of opposed acting gas springs being provided to act on the displacer end and rod assembly area end of the displacer and rod assembly so that a spring-mass system is formed having a natural frequency of oscillation substan-tially the same as the desired frequency of operation of the Stirling engine. One end of the displacer is designed to have a greater effective area acted upon by the gas contained within the engine than the effective area of the opposite end whereby the unbalanced areas of the opposing displacer ends create a differential force when acted upon by a periodic pressure wave, causing reciprocating motion of the displacer and virtual rod assembly.  In the preferred embodiment a displacer electrodynamic machine is  provided  for  selectively driving or  loading the displacer and rod assembly to thereby control the stroke and/or phase angle at which the displacer and rod assembly move relative to the output power piston or work member.

The flame retardancy is achieved by the addition of antimony compounds and halide flame retardants.  High impact resistance is achieved by the incorporation of a rubbery polymer into the polymeric composition.

Abstract: Abstract of the Disclosure An apparatus for drilling vertical temperature measuring holes in the top brick of coke ovens includes a guide support vertically fixedly mounted on a horizontal frame on the top surface of a coke oven proper, and a guide pipe shaft connected at its upper end to a rotary drill, having a freely replaceable drilling bit attached to its lower end and including therein a cooling gaseous body passage is vertically movably mounted on the guide support in parallel thereto.  In drilling operation, a first core bit with square chips is attached to the lower end of the guide pipe shaft and the top brick is first drilled to a depth of at least five times of diameter of the hole to be drilled while jetting a cooling gaseous body and cooling the core bit.  Then, the bit is replaced with a second core bit with circular chips and the hole is drilled further down to near the desired depth while similarly cooling the bit and then the second bit is again replaced with a planer type drill bit with ventilation holes thus plaining the hole bottom while cooling the drill bit and thereby vertically drilling the high temperature brick without greatly damaging the inner wall of the drilled holes.

Abstract: IMPROVED SIDE WALL MEMBERS FOR CONTINUOUS CASTING MOLDS          ABSTRACT OF THE DISCLOSURE                Improved side wall plate members for an adjustable width, continuous casting mold. The adjustable width continuous casting mold is formed of a pair of opposed, spaced apart front and rear mold wall members and a pair of opposed, spaced apart side wall members with the side wall members clamped between the front and rear mold wall members. The improved side wall members of the present invention prevent scratching and wearing of the surfaces of the adjacent front and rear mold walls during mold width adjustment and also prevent twisting or tilting of the mold wall side members during such adjustment. Furthermore, the improved side wall members avoid the formation of flash producing gaps or spaces at the corners of the mold. Each sidewall member according to the present invention, includes, along its side edges, i.e., the edges in contact with the adjacent front and rear mold wall members, a bearing surface formed of a low friction, thermally stable, compressible, memory material. The bearing surface is preferably an insert positioned in a socket or groove within the side edge of the side wall member. The bearing surfaces or inserts are compressed when the mold cavity is clamped together so that the side edges of the side wall members are in contact with the front and rear mold wall members. When it is desired to adjust the width of the mold cavity, the inserts expand beyond the side edges of the side walls into contact with the adjacent front and rear mold wall members.
