Abstract: An improved differential pressure capillary viscometer in which a sample of solute in solution with a solvent is introduced into a stream of flowing solvent.

The pressure differences can be related to the viscosity of the sample.

Abstract: Solvent-based thermosetting coating composition comprising a hydroxy functional epoxy ester resin, linear polycaprolactone diol and blocked polyisocyanate crosslinking agent. The coating composition may be formulated as hot sprayable, high solids coating composition suitable for use as chip resistant automotive vehicle primer adapted for use on body panel areas subject to chipping by stones, gravel and other road debris.

Abstract: A flagpole assembly includes a hollow pole and a winch at the base of the pole. A halyard is connected to the winch, extends through the hollow pole and out an exit opening at its tip. The inner edge of the flag is removably mounted to fixed positions along an elongate flag trolley to keep the inner flag edge extended. The flag trolley includes an elongate U-shaped channel to which two pulleys are mounted. The halyard passes from the exit opening, around one pulley, between the legs of the channel and around the other pulley. The outer end of the halyard is fastened to a shock absorbing anchor mounted along the hollow pole. Winding and unwinding the halyard onto and from the winch causes the flag to raise and lower as the length of the halyard between the exit opening and the anchor increases and decreases. The weight of the flag trolley, with or without the flag, is sufficient to pull the halyard from the pole when the winch is unwinding the halyard.

Abstract: A pipe machining apparatus having a tool carrier rotatable about a frame mounted externally of a pipe, with the frame being formed of two semiannular sections which are releasably held together by connection devices including coacting pin and latch structures which are effectively positioned by means operable from the side of the frame. The tool carrier mounts at least one tool head having a tool slide for a tool movable radially of the pipe. The tool slide is movable by rotation of a feed screw which is rotated in a tool slide advancing direction by a rack and pinion structure including a rack adjustably mounted on a feed plunger which coacts with a tool advance cam on the frame. The rack is also mounted for pivotal movement to permit manual rotation of the feed screw in a tool slide retracting direction, which pivoting results from cogging of the pinion gears relative to the rack gears.

Abstract: An apparatus wherein there is provided a source of fiber forming material, with said fiber forming material being pumped into a die having a plurality of spinnerets about its periphery. The die is rotated at a predetermined adjustable speed, whereby the liquid is expelled from the die so as to form fibers. It is preferred that the fiber forming material be cooled as it is leaving the holes in the spinnerets during drawdown. The fibers may be used to produce fabrics, fibrous tow and yarn through appropriate take-up systems. The pumping system provides a pumping action whereby a volumetric quantity of liquid is forced into the rotational system independent of viscosity or the back pressure generated by the spinnerets and the manifold system of the spinning head, thus creating positive displacement feeding. Positive displacement feeding may be accomplished by the extruder alone or with an additional pump of the type generally employed for this purpose.

Abstract: This method provides a filtering of digital samples of speech signal by a linear-prediction inverse filter, whose coefficients are chosen out of a codebook of quantized filter coefficient vectors, obtaining a residual signal subdivided into vectors. The weighted mean-square error made in quantizing said vectors with quantized residual vectors contained in a codebook and forming excitation waveforms is computed.The coding signal for each block of samples consists of the coefficient vector index chosen for the inverse filter as well as of the indices of the vectors of the excitation waveforms which have generated minimum weighted mean-square error. During the decoding phase, a synthesis filter, having the same coefficients as chosen for the inverse filter, is excited by quantized-residual vectors chosen during the coding phase (FIGS. 1, 2).
