Abstract: ABSTRACT OF THE DISCLOSURE         A cam cleat for use in a sailboat environment having a base plate and a pair of cam elements pivotally mounted on the base plate about spaced axes normal to the base plate.  The cam elements have eccentric confronting faces that coact to define a line-gripping nip therebetween.  The cam elements are pivotable about the axes of the cam elements to permit a line to enter the nip and to pass therethrough in one direction only axially of the line and to hold the line against retrogressive movement in the opposite axial direction.  Inclined surfaces cooperate to define a V-shaped gap into the nip.  The V-shaped gap is located above the nip.   The inclined surfaces have serrations thereon which lie (seen from above) tangent to circles, the center of which are coincident with the axes of the cam elements and which are inclined in the opening direction and are parallel to each other to effect, upon movement of the line toward the nip, a pivotal movement of the cam elements by an amount sufficient to receive the line within the nip without necessitating an axial movement of the line therethrough.

Abstract: Abstract A process and apparatus is disclosed for the removal of pollutant material including solid or liquid particulate matter and gaseous pollutants from gas streams in which the gas is driven through a mixing tube by forming a jet of a compressible fluid such as steam or air or the whole or a part of the polluted gas itself. In some instances the jet acts as an ejector to induce flow of the polluted gas into the mixing tube but when all of the polluted gas is formed into a jet it is directed into the mixing tube without any ejector action.  A mechanically atomized liquid is introduced into the outer region of the jet of compressible fluid emerging from the nozzle in which the jet is formed.  The mechanically atomized liquid is further atomized by the shearing action of the jet to form high velocity droplets which are intimately and turbulently mixed with the pollutant-containing gas and retained in the mixing tube for a sufficient time so that the pollutants become entrained with the water droplets.  The turbulent mixture is then directed into a diffuser having an increasing cross-sectional area and deflected as it enters the diffuser away from one portion of the interior surface of the diffuser and toward an opposite portion of the in-terior surface of the diffuser and also decelerated so as to cause a separation in the flow of the liquid and non-liquid constituents of the mixture.  Apparatus is disclosed including a compressible fluid nozzle for forming the jet and a liquid injector, a mixing tube, a diffuser, and fluid and mechanical separating means whereby a separate flow of the particulate material including submicronic sized particulate entrained in liquid droplets is established in the diffuser for removal from the cleaned gas stream.  If it is desired to remove reactive gaseous pollutants from a gas stream, appropriate chemical reagents may be added to the injected liquid or directly to the gas stream prior to treatment.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved heater cast used in multi-cavity hot runner edge gate injection molding.          The improved heater cast enables products to be molded of considerably lower heights than was previously the case and as well facilitates the molding of difficult heat sensitive material such as PVC, polycarbonate, polyester and acetal resins.  The improved heater cast has a cylindrical mid portion with four spaced cylindrical lower nozzle portions extending downwardly around the periphery therefrom.  The hot melt flows downwardly from the molding machine, through a central injection passage in the heater cast and branches into four injection passage extensions to the respective gates and cavities.  The provision of the four lower nozzle portions enables the cavity plate to nave a raised table portion therebetween which provides addi-tional strength and cooling.  The provision of a cylindrical mid portion enables an extruded cylindrical TEFLON glass filled insulation sleeve to be located between it and the surrounding cavity plate to facilitate faster colour and material changes without streaking problems and to be a permanent insulator against heat loss to the cavity plate.

Abstract: LEAF SPRING WEIGHING SCALE WITH OPTICAL DETECTOR               Abstract of the Disclosure A weighing scale having a tare structure carried by a pair of vertically spaced parallel leaf springs includes an optical detector having an apparatus for generating a moire fringe pattern and moving the pattern with scale tare deflection.  One of a pair of ruled parallel grating sets is fixed while the other is mounted to the tare structure in movable, parallel alignment with the fixed set.  A beam of light projects through both grating sets to project the pattern on a photodetector array carried by the scale frame. Upon placement of a load on the scale, deflection of the tare structure results in linear movement of successive fringes across the photodetectors and the sequential generation of weight indicative signals.  The photodetectors are secured to a rotatable base for adjustment of the effective spacings between each photodetector with respect to fringe pattern image.

Abstract: TITLE               NOISE DETECTING CIRCUIT              ABSTRACT OF THE DISCLOSURE         A noise detecting circuit for a data processing channel operates on incoming noise pulses and trains of data pulses, each train of which is preceded by a start pulse of a duration substantially greater than the char-acteristic duration of a noise pulse.  The noise detecting circuit generates a noise verification pulse in response to a first incoming pulse after a predetermined interval of time following the receipt of the first incoming pulse, which interval is greater than the characteristic duration of a noise pulse and less than the duration of a start pulse.  Consequently, there is time coincidence between the noise verification pulse and the first incoming pulse if the first incoming pulse is a start pulse but there is no time coincidence between the noise verification pulse and the first incoming pulse if the first incoming pulse is a noise pulse.  Means are included for detecting such non-coincidence and for generating an inhibit signal to indicate that the first incoming pulse is a noise pulse and to inhibit a data processing channel from processing the next incoming pulse.

Abstract: ABSTRACT      An automatic swimming pool cleaner comprised of a car adapted to travel underwater along a random path on the pool vessel surface for dislodging debris therefrom.  The car wheels are driven by a water powered turbine to propel the car in a forward direction, along the vessel surface. In order to prevent the car from being driven into a position, as for example against a vertical wall, from which it cannot emerge, a wheel geometry is employed which, upon contact, develops a horizontal force component parallel to the vertical wall, to thus enable the car to spin off.  Alternatively, or in combination, a water flow produced reaction force can produce a torque to turn the car with respect to the engaged wheel to enable the car to spin off.  The car is designed with a low cen-ter of gravity and a relatively buoyant top portion so as to produce a torque which maintains the car correct side up when on the pool bottom. Means are provided on the car for producing a water flow having a force component perpendicular to the vessel surface to provide good traction between the car wheels and the vessel surface. Further, a water flow produced suction is created adjacent to the vessel surface for collecting debris into a basket carried by the car.  In addition, one or more hoses is pulled by the car and whipped by water flow to sweep dirt from the vessel surface.
