Abstract: Abstract of the Disclosure Treated glass fibers having improved utilization of silane coupling agents are produced which have good strand handling and processing properties and which result in reinforced polymeric materials having good strength properties and good UV color stability.  The treated glass fibers having an aqueous treating composition present on a substantial portion of the surface of the glass fibers, wherein the aqueous chemical treating composition has an aqueous dispersion of an internally silylated polyurethane polymer having siliconate anions and one or more dispersing agents in at least an effective dispersing amount, and water in an amount to give a total solids for the aqueous chemical composition for treatment of the glass fibers.  The one or more dispersing agents, can be present as external dispersing agentes in which case their amounts could be both an effective dispersing amount and an effective lubricating amount.  In addition, the dispersing agents can be present with the internally silylated polyurethane polymer as an internal hydrophilic additive like nonionic and/or ionic and/or ionic precursor dispensing agents.  In this case, the aqueous chemical treating composition has a glass fiber lubricant present in an effective lubricating amount.  The internally silylated polyurethane may also have internal hardening segments to provide hardness to the polyurethane film formed on the glass fibers.  The treated glass fibers can be used in reinforcing thermoplasitic and thermosetting polymeric materials in various forms of continuous glass fibers and strand and chopped glass fibers and strands and mats of glass fibers and strands.

Abstract: ABSTRACT OF THE DISCLOSURE A sludge lance nozzle for removing sludge from between the tubes of a nuclear steam generator includes positioning apparatus mounted on top of the nozzle.  The tubes are arranged in rows and columns with the axes of the tubes in each column lying in a common column plane. The nozzle is moved perpendicular  to  the  column planes close to one of the rows of tubes.  In one embodiment, the positioning apparatus comprises two transmitter/receivers for transmitting signals and receiving reflected signals along axes parallel to the column planes, the axes being spaced apart by odd multiples of one-half tube pitch.  The received  signals  are  subtracted  to  produce  a  position indicating signal.  In another embodiment the positioning apparatus includes  a transmitter  and  a  receiver  spaced apart  in the  direction of movement  of  the nozzle,  the transmitter transmitting a signal in a first predetermined direction,  and  the  receiver  being  responsive  only  to reflected  signals  received  from  a  second  predetermined direction.

Abstract: ABSTRACT                       Proximity Sensor (With reference to Figure 1 of the drawings) In a proximity sensor (Figure 1 and 2) an electrical circuit is formed by a slot 10 in an elongate conductive strip 11.          The strip 11 carries a magnet 12 having a pole piece 14 protruding through the strip 11 at one end of slot 10.  At the other end of the slot 10 pass laminations 15 which magnetically couple the electrical circuit and a multi-turn coil 16 on a former 17 attached to the strip 11. The coil 16 is terminated at an output pair 18.  A ferrous object passing in the vicinity of pole piece 14 modifies the flux pattern at the pole face.  The resultant flux changes, being tightly coupled to the electrical conductor 11 induce a low voltage high current emf into the conductor 11, which forms the primary turn of a current transformer.  The secondary of the current transformer is formed by the close coupled coil 17, which has multiple turns, dependent upon the output voltage required at output pair 18.  The invention overcomes the problem of providing a proximity sensor which can operate at a high temperature since the strip 11 may be uninsulated, without consequent danger of insulation breakdown, as with prior art multi-turn arrangements.

Abstract: FLUORESCENT INDICATOR DYES FOR CALCIUM IONS                       ABSTRACT        The present invention discloses a new class of highly fluorescent indicator dyes that are specific for calcium ions.  The new fluorescent indicator dyes combine a stilbene-type fluorophore with a tetracarboxylate parent Ca2+ chelating compound having the octacoordinate pattern of liganding groups characteristic of EGTA and BAPTA.  Preferred forms contain extra heterocyclic bridges to reinforce the ethylenic bond of the stilbene and to reduce hydrophobicity.  Compared to their widely used predecessor, "quin2", the new dyes offer up to thirty-fold brighter fluorescence, major changes in wavelength (not just intensity) upon Ca2+ binding, slightly lower affinities for Ca2+, slightly longer wavelengths of excitation, and considerably improved selectivity for Ca2+ over other divalent cations. These properties, particularly the wavelength sensitivity to Ca2+, make the dyes useful indicators for many intracellular applications, especially in single cells, adherent cell layers, or bulk tissues.         The present invention also discloses an improved method for synthesizing alpha-acyloxyalkyl bromides wherein the bromides so synthesized are free of contaminating bis(1-bromoalkyl)ether.  The improved method is exemplified herein in the synthesis of acetoxymethyl bromide, a compound useful in preparing the acetoxymethyl esters disclosed herein as novel Ca2+ specific fluorescent indicators.

Abstract: ABSTRACT           A method of thermal deburring of metal parts, consisting in that the process is carried out in a cham-ber in two stages.  The chamber is initially filled with a mixture of a combustible gas and air, the amount of each component in the mixture and the pressure thereof being dependent on the necessity to ensure the burning-out of oils and evaporation of moisture from the surface of parts being treated.  The mixture is subsequently ignited.  As a result, the moisture evaporates, and the oils burn out.  Products of combustion are then expelled from the chamber, and the latter is filled with a mix-ture of a combustible gas and oxygen.  Said mixture is ignited, and the burrs on the parts are burnt down.

Abstract: Abstract of the Disclosure A driver assembly for the pad of a high speed floor burnishing machine includes a flexible backing plate having a peripheral retaining skirt which centers the pad on the driver assembly and also prevents the edges of the pad from growing or expanding to a larger circumference during high speed rotary burnishing action.  The backing plate adds stiffness to the pad when rotating at high speed, and it promotes uniform contact of the pad with the floor at the outer radial extremities of the pad where the velocity is greatest and the polishing is most effective.  In the illustrated embodiment, the pad and driver assembly are surrounded by a shroud which is continuously evacuated by radial air flow generated by the motion of the driver assembly which includes a finned hub.   The air flow carries debris generated by the burnisher to a collection bag or filter without leaving the machine.

Abstract: ABSTRACT OF THE DISCLOSURE           A piezoelectric bimorph scanner is disclosed which has a flexural beam attached to the free end of a cantilever mounted piezoelectric bimorph crystal. A mirror is bonded to the flexural beam a predetermined distance from the bimorph crystal. An AC voltage of predetermined frequency is applied to the bimorph crystal causing the flexural beam to oscillate with a node at the center of the mirror. The mirror rotates about the node rather than swinging in an arc, enabling the scanner to deflect a collimated light beam over a larger deflection angle than heretofore possible without additional light beam control apparatus. In an alternate embodiment, a laser diode may be mounted on the flexural beam instead of the mirror, further reducing costs and components.

Abstract: ABSTRACT A dielectrically stabilized planar GaAs FET oscillator has a single gate transistor with a gate terminal and a drain terminal.  A cylindrically shaped dielectric resonator is mounted on a ceramic support. The dielectric resonator resonates in a TE01 mode and is located on the gate line of the transistor a predeterminated distance from the gate terminal.  The transistor is biased so that the dielectric resonator alone can stabilize the power produced by the transistor.  Stabilized output power is obtained from both the drain terminal and the gate terminal.  With previous oscillators having a single gate transistor, output power could only be obtained from one terminal.
