Abstract: Abstract of the Invention To separate solid and liquids contained in aqueous dispersions of solids, which may also be oil-bearing, a flocculating agent is added to the dispersion while flowing through a pipe, the flowing aqueous dispersion then subjected to a flow restriction to mix the flocculating agent and flocculate the solids and the thus treated dispersion discharged onto a surface permitting free liquid run-off and deposition of the floc. The process is particularly applicable to oil-bearing waste water sludges and waste oil sludges. The process facilitates recovery of the oil and land forming of the solids.

Abstract: ABSTRACT      An anode for hydrogen oxidation in a fuel cell is formed from a host matrix including at least one transition element which is structurally modified by the incorporation of at least one modifier element to improve its catalytic prop-erties.  The catalytic body is based on a dis-ordered non-equilibrium material designed to have a high density of catalytically active sites, resistance to poisioning, and long operating life.          Modifier elements, including Ti, Mo, Zr, Mg, V, Si or Al, structurally modify tile local chemical environment of a nickel or other transition ele-ment host matrix to form the catalytic materials of the anode.  The improved low overvoltage cata-lytic materials of the anode of the present inven-tion increase the operating efficiencies of fuel cells employing such anodes.  The catalytic mate-rials can be deposited as a layer on the surface of porous electrode substrates to form a gas dif-fusion anode or can be formed as a gas diffusion electrode.

All of the passages have a circular cross section along substantially the entire length of the pas-sages.  All of the inserts are of a configuration such that the passages of each blasthead are aligned with the passages of the other blasthead, so that the gas impinges on the glass surfaces in an opposed relationship with a uniform pattern over said surfaces thereby optimizing the degree of glass tempering.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention is directed to a process for preparing an advanced epoxy resin by reacting (a) a compound bearing an average of more than one vicinal epoxide group per molecule with (b) a polyhydric phenol or thiophenol, in the presence of a catalytic amount of a tetrahydrocarbyl phosphonium salt.  The invention is characterized in that the reaction is conducted under conditions such that the reaction and exotherm tempera-ture does not exceed 175°C and the reaction medium is essentially anhydrous.  These conditions are shown to prevent significant deactivation of the catalyst. Advanced epoxy resins produced by this process are generally less colored and have epoxy equivalent weights closer to the theoretical values than prior art resins produced in the conventional manner using phosphonium salts as catalysts.           The process of this invention also includes the optional step of adding a sufficient amount of a phosphonium ylid quenching agent to selectively deac-tivate the catalyst without substantial reaction with the advanced epoxy resins.

Abstract: PROPORTIONAL SOLENOID VALVE            ABSTRACT:           A diaphragm operated valve assembly is  con-trolled by an electromagnetic valve assembly (10).   A flat disc armature  (422), which forms part of a flux path, is operable in an inner chamber (118)to modulate the flow between the inner chamber  (118)  and an exit port (28) in response to an applied magnetic force.  The level of the effective magnetic force is a function of the armature mass (422), the pressure acting on the disc surface and the magnetic reluctance.   A pole piece (416) adjacent to the flat disc armature (422) includes a seat (20) and is at a fixed distance from the armature (422).          Variation of an air gap (x) provides a means to adjust the magnetic reluctance of the electromagnetic valve (10) after its final assembly and in this case an adjustment air gap is provided at the top member (414) of the flux path.  Such valves may thus be calibrated to operate at various pressure or flow rates as a func-tion of electrical power input, that is a variation of current or voltage.   These electrical power variations determine at what operating condition the flat disc armature (422) will contact the seat (20) and seal fluid flow.

Abstract: Abstract Digital Synthesis Technique For Pulses Having Predetermined Time And Frequency Domain Characteristics A digital synthesis technique provides pulse shaping in accordance with predetermined time domain and frequency domain constraints.  In the technique, the informational content of a binary bit stream is used by an access circuit (12) to form address words for accessing a read-only-memory (13).          The digital representations stored in the ROM (13) represent a superposition of temporally-displaced truncated impulse time functions) each weighted by the discrete transmission symbol levels of the analog output signal.  The digital representations from two ROMs (13-1 and 13-2) are toggled by a sequencing circuit.  In other embodiments of the invention, different memory arrangements ranging from a single ROM (142) to an array of ROMS (163-1 through 163-3 and 164-1 through 164-3) are respectively used to decrease circuit complexity.  In a digital radio transmission application of the technique, this arrangement is economical; readily reproducible and stable since it obviates the need for conventional complex analog filters.
