Abstract: Abstract of the Disclosure A method and apparatus are provided for determining the count per unit volume, that is, the density of particles such as platelets in diluted whole blood.  The invention involves use of known information, namely, the count per unit volume of other (reference) particles, such as red blood cells, also suspended in the same sample of liquid. The other particles are generally distinguishable from the particles of unknown count per unit volume by a difference in some measurable characteristic of the particles, such as size.  One embodiment of the invention is characterized by generating electrical pulses which represent detected particles in a sample of liquid of undetermined volume; discriminating between pulses which have different characteristics; separately counting such pulses until the count of particles of known density reaches a corresponding preset number or until a predetermined period of time has elapsed, or until the entire sample of liquid under test has been tested; and displaying the total count of particles of previously unknown density.  This total count either corresponds directly to the density of such particles or is an easily con-verted indication of such particle density.

Abstract: ABSTRACT OF THE DISCLOSURE  Fluorinated ion exchange polymers which have both pendant side chains containing carboxylic groups and pendant side chains which contain sulfonyl groups, when used in the form of membranes to separate the anode and cathode compart-ments of an electrolysis cell, permit operation at high current efficiency.  They are made by oxidation of flourinated polymers which have pendant side chains containing sulfinic groups, or both sufinic and sulfonyl groups.  The fluorinated polymers which have pendant side chains containing sulfinic groups, or both sufinic and sulfonyl groups, are in turn made from fluorinated polymers which have pendant side chains con-taining sulfonyl halide groups by reduction with, for example, hydrazine.  Fluorinated ion exchange polymers which have pen-dant side chains containing -OCF2COOR groups and also pendant side chains which contain sulfonyl groups can also be made by copolymerization of a mixture of monomers, one of which is a vinyl monomer which contains the indicated carboxylic group; and also by treatment of a polymer which contains -OCF2CF2SO3H or salts thereof with a combination of fluorine and oxygen.

Abstract: ABSTRACT OF THE DISCLOSURE A removable and reusable plastic screw anchor for fastening fixtures and other objects to a hollow wall.  The anchor includes a four-legged diamond-shaped shank whose front legs are joined together by a front apex hinge and whose rear legs are joined to the frong legs by side apex hinges, the ends of the rear legs defining a rear apex. Secured by a pair of normally outstretched resilient webs to the rear legs of the shank is a flanged socket whose bore lies in registration with an opening formed in the front apex hinge.  The diamond-shaped shank is collapsible to form a tongue that is insertable in a hole drilled in the wall to accommodate the socket, the webs then reverting to their outstretched condition to cause the shank which is now behind the wall to re-cover its diamond formation.  When a self-tapping screw is turned into the socket bore, it acts to thread the bore.  As the screw proceeds beyond the bore, it compels the shank to assume the configuration of a triangular truss whose bottom chord is defined by the rear legs and is pressed against the inner surface of the wall, the truss having a central strut formed by the screw when it extends between the front apex and the socket.  To remove the anchor from the hollow wall, one simply withdraws the screw to permit collapse of the truss.   The same anchor may be inserted in its tongue configuration in a hole drilled in a solid wall, the screw then serving to dilate the legs to wedge the tongue in the hole.

Abstract: Abstract of the Disclosure In an ammonia manufacturing operation a normally gaseous hydrocarbon or a vaporized naphtha is steam reformed and shift converted, in the presence of air to produce a relatively hot water vapor-containing gaseous stream containing nitrogen and hydrogen in substantially stoichiometric proportion for the production of ammonia along with carbon dioxide and with minor amounts of carbon monoxide.  The hot gaseous mixture is then cooled to remove water vapor therefrom as water and oxygen, usually in the form of air, is added to the resulting cooled gaseous mixture which is contacted with a catalyst for the selective oxidation of the carbon monoxide therein to carbon dioxide in the presence of hydrogen.  The oxygen is provided in part by air diverted from the steam reforming and in part by supplemental air.  The resulting gases, now having a substantially reduced carbon monoxide content, are then treated for the removal of carbon dioxide and optionally to methanation to convert residual carbon oxides therein to methane.          The resulting treated gases are subjected to contact with a catalyst under high pressure and at an elevated temperature for the conversion of the nitrogen and hydrogen in the treated gases to ammonia.

Abstract: ABSTRACT OF THE DISCLOSURE   A method is provided herein for building an improved positive drive power transmission belt having a plurality of alternating grooves and teeth for meshing with the teeth of a pulley, the drive belt being provided with reinforcing fibers distributed through at least a portion of each tooth.  An improved apparatus for building such a belt is also provided herein.  The method includes the steps of:  wrapping a tooth-covering fabric around a cylindrical mold which has circumferentially spaced alternating axial grooves and ridges;  wrapping a layer of fiber-loaded elastomeric material around the covering fabric;  applying pressure in a helical fashion against the elastomeric layer with a pressure-applying member to force at least a portion of both the fiber-loaded elastomeric material and the fabric into the axial grooves and to move a portion of the fiber-loaded elastomeric material away from the fabric in the area of the ridges to allow a later-wound load-carrying cord to lie against the fabric in the area of the ridges; winding a load-carrying cord in helical fashion and in a plurality of turns against the layer of the fiber-loaded elastomeric material;  wrapping a layer of elastomeric material over the load-carrying cord to define an assembly; and vulcanizing the assembly under heat and pressure;  wherein the pressure applying step and the winding step are carried out simultaneously with the cord being helically wound on a next succeeding turn following the application of pressure in the helical fashion.  Such method provides belts with a greater degree of length control than those made by the tooth preform method; and provides belts having greater strength and modulus of the belt teeth than those provided by the flow-through method.
