Abstract: TEXTURED POLYURETHANE SURFACE                Abstract of the Disclosure A textured polyurethane surface is created from a vinyl substrate by first forming a smooth, uncured polyurethane coating on the substrate and then heating the thus coated sub-strate to a temperature between about 100° and about 160°C for 1 to 10 minutes followed by heating to temperatures of 170° to 210°C for 0.5 to 10 minutes.  A textured surface may also be provided on a vinyl substrate having a previously cured polyurethane coating thereon by waiting at least about 1 week after the urethane coating has been cured and then heating the coated substrate to a temperature between about 140°C and about 210°C for 0.1 to 10 minutes.  A preferred application is in the creation of textured surfaces on sheet vinyl floor and wall coverings coated with polyurethane.

Abstract: ABSTRACT OF DISCLOSURE          Oil fence especially adapted for the defining of impurities on a water surface and made of a web of cloth shaped material.  The web exhibits alternating connected portions and multiple layer portions made in such a manner that between the layers of the multiple layer portions pockets and/or channels are formed, which are defined by the single layer portions, in order to receive for one thing float bodies for the support of the oil fence in water, and for another thing sinking weights in order to give the oil. fence the intended upright position in the water.  The present cloth shaped web comprises a pre-ferably impregnated and/or coated textile material, which is woven with alternating single layer portions forming said connected portions and portions with at least two layers, between which said pockets and/ or channels are formed.  The single layer portions are by means of a per se known weaving technique shaped from the interwoven weft of the converging layers of the adjacent multiple layer portions, thereby obtaining an extremely strong connection of said portions.

Abstract: SYSTEM FOR SELF-CLEANING INK JET HEAD          Abstract A system for fluid jet heads such as ink jet adapted for self-cleaning of certain clogs and purging of air from the head.  The head includes a manifold communicating with at least one orifice to project a stream of fluid therefrom.  Two fluid supply paths at different sides of the manifold supply pressurized fluid thereto.  One of the supply paths is located at the top of the manifold and is reversible.  If air or an impurity causing a nozzle clog is encountered in the head, the top path may be reversed so the fluid enters from one path and exits at the top.  This establishes a crossing flow at the orifice, tending to loosen and remove the clog and purging the impurity or air from the head and out the reversible path.

Abstract: ABSTRACT OF THE DISCLOSURE         A humane animal trap has a pair of pivotally connected jaws each having a circular periphery, the jaws being spring-biased to a closed position.  The jaws may be automatically set in an open position and to that end one jaw has a pair of rail members extending through the other jaw which members pivotally support a sear member provided with locking means in the form of a notch.  The other jaw has a projection thereon extending to between the rail members.  As the jaws are moved apart the pro-jection will be brought into registry with the notch and will automatically engage therewith to hold the jaws apart.  Bait is secured to a holder attached to the sear member and when an animal attempts to take the bait the notch disengages from the projection allowing the spring to strongly drive the jaws together, trapping the animal.  The automatic nature of the setting mechanism means that the trap will be safer for the user as he can devote all his strength to the opening of the trap without having to think about or act separately on the setting or trigger mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE :       The invention relates to a new device for discharging smokes, fumes and greases from various indoor premises and comprising a set of ceiling elements arranged with smoke, fumes and grease discharging slits therebetween.       It is characterized in that the ceiling elements it includes are hollow and crossed by water whose circulation is ensured by pipes interconnecting the elements, which elements form condensers with water-cooled heat-transfer surfaces.       Discharging of the grease deposits collected on the condensers in effected by washing with water containing a detergent, this water being supplied by spray-rails, while the washing water and the dissolved greases are collected by the drains.       Hoods are provided above the slits separating the drains (the latter being close to one another) in order to completely secure the premises against dripping of the greases and washing water during the cleaning operation, which is performed only when it proves necessary.

The  fluid is directed through a first direct contact heat exchanger in heat transfer relation with a working fluid  of a  type  insoluble  in  a  liquid including inorganic salts.  The vaporous working fluid thus produced is expanded through a  prime mover  and  then  directed  through  a second direct contact heat exchanger.  The vaporous fluid is condensed in said second direct contact  heat exchanger by passing in heat transfer relation with a relatively cold heat exchange medium comprising a liquid  brine solution.   The condensed working fluid is thereafter returned to the first direct contact heat exchanger for repeated reuse in the cycle.   Inorganic  salts  are  mixed  with either the geothermal heated fluid or the  relatively  cold  heat  exchange  medium  to maintain  the  percentage  by weight of inorganic salt in each of the fluids above a predetermined value  to  prevent  the  working fluid from being absorbed therein.

Abstract: ABSTRACT OF THE DISCLOSURE A histogram of the volume of the particles in a sample of fluid-suspended particles, including those in the submicron region, can be obtained by using an incident light beam having a wavelength approximately twice the average particle diameter in each of the ranges of partical sizes making up the histogram.  The 90° scatter from the sample is measured in two orthogonal polarizations.  The first polarization has its electric vector perpendicular to the plane containing the point of observation and the incident light beam and the second is parallel to that plane.  The magnitude of the light flux having the second polarization is subtracted from that having the first polar-ization in each range to give a measure of the volume of the particles in that range.
