Abstract: "METHOD FOR CARPET CLEANING"     ABSTRACT         The invention relates to a carpet cleaning method wherein a fine spray of cleaning solution is uniformily applied to the carpet in an amount not more than necessary to dampen it.  A preferred cleaning solution in the form of a non-ionic surfactant is disclosed.  Once the cleaning solution is sprayed on the carpet, a cleaning pad, having a soft textile fiber pile, is then vigorously rubbed over the surface of the carpet to be cleaned, preferably in a rotary motion.  This rotary motion can be accomplished through the attachment of the cleaning pad to a carpet cleaning machine as described.  The cleaning pads may also be soaked in an aqueous solution of an electrolyte and wrung dry before use, and are replaced by clean pads when soiled.

Abstract: ABSTRACT    A device for separating granular material from a fluid flow includes a first section for reducing the kinetic energy of the fluid flow, a second section for dividing the fluid flow into two portions containing greater and lesser proportions respectively of said material, and a third section comprising a settling tank or succession of settling tanks 6,9,12.  The first section includes an inlet pipe 1 which is bifurcated, the two bifurcations opening to opposite sides of a chamber 2 whereby the divided flows collide and reduce the kinetic energy of the flow as a whole.   The second section comprises one or more inclined channels 4 receiving the fluid flow from the bottom of the chamber, each channel having in its bottom wall an aperture provided with a deflector plate 5 arranged to direct through the aperture and into the first settling tank 6 the lower strata of the fluid flow along the channel. The remainder of the fluid flow is directed into an intermediate tank 9 in the succession.

Abstract: C-14-53-0277 METHOD FOR MAKING BICOMPONENT FILAMENTS ABSTRACT OF THE DISCLOSURE The method for making bicomponent filaments from two spin dopes wherein the dopes are assembled into al-ternating layers in a feed tube leading to a transition tube connected to a conventional spinnerette, the layers then being fed through the transition tube and the spin-nerette to form filaments. The feed tube has a constant cross-sectional area along the length thereof and the transition tube has a parabolic configuration such that the linear flow rate of the assembled dope layers passing through the transition tube decreases at a uniform rate as the cross-sectional area of the stream of assembled layers is increased to the cross-sectional area of the spinnerette, to thereby maintain the distinctness of the interfaces of the layers and thus insure that good bi-component filaments will be formed.

Abstract: Abstract This invention relates to the measurement of the temperature and/or mass flow rate of a free falling molten stream of material. Previous  techniques  have  not  recognized  the  effects  temperature variations of the molten stream of material have on the measurement of the above flow properties.   The present invention utilizes a line scan camera having photodiodes disposed in a predetermined array to measure the temperature and mass flow rate of a moving mass of molten material.   This is accomplished in the present invention by limiting the maximum voltage generated by any one photodiode exposed to light energy of a mass by varying the scan rate and thus the exposure time of the photodiodes in response to a variance in the light intensity and thus the temperature of the molten mass of material.

Abstract: ABSTRACT OF THE DISCLOSURE     The pressure of a heated fluid is reduced in a test chamber.  A small vent in the upper portion of the test chamber receives a stream of liquid from the chamber and yields a steady hiss when the fluid in the test chamber is under sufficient pressure to maintain the fluid solely in the liquid phase and it yields a sputtering hiss sound when the pressure in the test chamber is reduced sufficiently to permit steam and/or gases to coexist with the liquid in the chamber thus permitting liquid plus vapor to enter the vent.  The change in sound may be used to alert an operator and/or pressure fluctuations in the test chamber may be automatically monitored to produce an output signal or a feedback signal for automatic control.

Abstract: THOMAS PETER SAPITOWICZ ROBERT ANTHONY MELONI                HAMMER FOR DOT MATRIX PRINTER                    ABSTRACT OF THE DISCLOSURE      Each hammer includes a frame-like portion with a recess into which an electrically energizable flat coil is received.  Affixed to opposite sides of the frame portion, and extending therefrom over the recess in contact with the sides of the coil, are thermally conductive metallic foil sheets which serve to dissipate heat from the coil, retain the coil intact and maintain the proper position of the coil relative to the frame.  The exterior surfaces of the sheets form bearing surfaces to protect the hammer and coil from wear caused by contact with other parts of the head as the hammer is displaced. An elongated recess is formed along the axis of a portion of the frame, in the direction of displacement, by cutting transverse slots therein so as to form a plurality of clamping elements, alternate ones of which are situated on opposite ii sides of the axis. A print wire is received within the recess and frictionally engaged by the elements so as to form a strong rigid joint without significantly increasing the mass or thickness of the hammer. The print wire is affixed to the frame portion at the center of percussion thereof to eliminate torsional vibrations, otherwise created on impact.

Abstract: ABRASIVE BRUSHES AND METHODS OF MAKING SAME                  Abstract Of The Disclosure An elongate, abrasive strip element is produced by winding an abrasive monofilament, or bundles thereof, back and forth in a zigzag pattern from side to side of the strip, and chain stitching together adjacent transverse sections of the  mono-filament, or bundles thereof.  The resultant strip is easily rolled or coiled about a transverse axis, but resists bending about a longitudinal axis, whereby it can be manipulated readily to form brush races of various configurations.  The warp yarns which are used to produce the chain stitches may be produced on a knitting machine which can be cammed to vary the number of stitches between adjacent transverse strands of the monofilament wefts, thereby selectively to vary the density of the brush races produced from the strips, and also to vary the configuration of the abrasive strip itself (i.e. to produce it in linear form, circular, truncated-conical, etc.).  The linear form of the strip may be severed medially of its edges to form two, identical bristle strips, each of which may be wound in convolute form, for example, and may be embedded at one side (e.g. by molding) in an elastomeric base to form a disc type brush.  Other brush con-figurations are also disclosed.

Abstract: FLOATING HIGHWAY ABSTRACT OF THE DISCLOSURE        The present invention is a floating highway unit which has a structure which facilitates both removal from linkage in a series of units forming the highway, provides means for simple alignment of the units during assembly, and also allows vertical movement caused by tides and waves.  Means is provided for protecting the highway by means of a partly floating barrier, for damping wave motion, thus substantially reducing the amount of absolute and relative movement of the floating highway units. Each of the floating units of the present invention is comprised of a generally rectangular horizontal pontoon including means for floatation of the pontoon, the pontoon having a centrally located horizontal tongue extending outwardly from a short side of the pontoon whereby the top surface of the tongue is an extension of the top surface of the pontoon.  A recess is located in the opposite side of the pontoon having a shape for enclosing the tongue which matches the shape of the tongue.  A slot extends across the width of the tongue, and a pair of in-line slots extends across at least part of each of the opposite sides of the pontoon into the recess on opposite sides of the recess respectively.  The latter slots are coextensive with the slot in a tongue of an adjacent pontoon when it is enclosed in the recess.  A key is inserted in the coextensive slots to retain the floating units together.
