Abstract: GAS PURIFICATION METHOD AND APPARATUS          Abstract of the Disclosure Pulverulent solid sorption agent is injected into a stream of noxious-contaminant-containing gas subjected to intensive turbulence and then separated from the gas.  The solid sorption agent is optionally reused until exhausted, or purified before reuse.  Apparatus is provided for the process.     Invention is predicated on a combination of two factors: a) solid sorption agent is introduced into a stream of contaminated gas in pulverulent form, and b) the gas stream is then subjected to intense turbulence prior to separating the sorption agent therefrom.

Abstract: HIGH NORMALITY ION EXCHANGE MEMBRANES AND METHOD OF PRODUCTION                   ABSTRACT OF THE DISCLOSURE         Anionic and cationic exchange materials including membranes are beneficiated by a method involving swelling the ion exchange material in the presence of an electrically neutral Reagent A and then contacting the swollen material with a similarly electrically-neutral Reagent B selected to interact with A forming in situ in the ion exchange pathways of the ion exchange material a chemical substance or substances which ionize the membrane to form bulky multi-charge entrapped ions of the same electrical sign as the covalently-bonded ion sites of the membrane material. The entrapped ions are electrostatically retained most tenaciously in the ion exchange channels of the membrane even when extracted with water or solvents and even when the membrane is put under electric stress as when current at high densities pass through the membrane in electrolytic chlorine processes, in dialysis cells, and the like.          As compared to existing membranes having a concentration of covalently-bonded ion sites averaging about 0.05 to 0.1N, beneficiated membranes may be made having a critical electrolyte concentration between about 0.25 and about 10N.          Beneficiated membranes at about 0.5 to 10N or higher reject ions of the same electric charge at ion concentrations well above those at which the original ion exchange material is effective.  Outstanding properties of such beneficiated membranes are very high ion transfer rates, low electrical-resistivities, very high permselectivities allowing them to function under very high ion concentrations, and high resistance to penetration or fouling by nonionized salts, all without loss of the basic physical and chemical integrity of the original membrane.  Beneficiated cation exchange membranes are especially useful in the electrolytic generation of chlorine.

Abstract: ABSTRACT OF THE DISCLOSURE            A process for the exchange of hydrogen isotopes between streams of gaseous hydrogen and liquid water is des-cribed, wherein the streams of liquid water and gaseous hydro-gen are simultaneously brought into contact with one another and a catalyst packed bed assembly while at a temperature in the range 273 to 573°K,  The catalyst packed bed assembly may be composed of discrete carrier bodies of e.g. ceramics, me-tals, fibrous materials or synthetic plastics with catalyti-cally active metal crystallites selected from Group VIII of the Periodic Table, partially enclosed in and bonded to the carrier bodies by a water repellent, water vapour and hydrogen gas permeable, porous, polymeric material, and discrete packing bodies having an exterior surface which is substantially hy-drophilic and relatively non-catalytically active with regard to hydrogen isotope exchange between hydrogen gas and water vapour to that of the catalyst bodies.  The catalytically ac-tive metal crystallites catalyze the hydrogen isotope exchange reaction between hydrogen gas and water vapour in the presence of liquid water while the polymeric material retards the loss of activity of the catalytically active metal crystallites cau-sed by contact thereof by the liquid water.  This catalyzed chemical isotope exchange proceeds simultaneously with isotope exchange from water vapour to liquid water by a non-catalyzed, physical evaporation and condensation exchange reaction and the addition of the discrete hydrophilic packing serves to increa-se this rate of isotope exchange between the water vapour and the liquid water.  In other embodiments the catalyst struc-ture and hydrophilic packing structure comprise a mixture of corrugated and flat metal sheet or gauze or a mixture of corrugated metal sheets or gauze packed or rolled such that fluid flow passage interstices are provided between the sheets and with the catalytically active metal crystallites deposited on some of the metal sheets or gauze.

Abstract: ABSTRACT OF THE DISCLOSURE                 A head for a lacrosse stick is provided herein.  It includes a generally V-shaped frame which is adapted to receive a web. The frame is defined by two side walls joined at a juncture and diverging therefrom.  A transverse wall joins the ends of the side walls opposite of the juncture.  Tab means are positioned on at least the side walls for secure-ment of a web onto said frame.  The tab means are integrally formed with at least the side walls and are constructed and arranged therewith to project inwardly from at least the side walls.  The tabs further have a top surface substantially flush with the top surface of at least the side walls.  Improved durability and enhanced play characteristics are realized due to the free-hanging character or free-suspension of the web which permits greater flexibility in forming or adjusting the ball pocket of the web.

Abstract: ABSTRACT OF THE DISCLOSURE            A pair of balancing weights are mounted on opposite sides of the center line of the rotor for movement about the axis of the rotor. The weights are automatically locked against movement about the axis of the rotor when the rotor is rotating below critical speed and automatically released for free movement about the axis of the rotor when the rotor is rotating above critical speed. The weights are exemplified as roller cages. The balancing weights are variously locked by mechanical clutches actuated at critical speed. The clutching for the weights is either individual or such that the weights are necessarily locked against movement and released simultaneously. Centrifugal force is used to control the clutches.

Abstract: ABSTRACT OF THE DISCLOSURE             A switching system is described for use in for example AM transmitters comprising at least one pair of semi-conductor output switches connected in series across an AM modulated D.C. supply and arranged to be operated sequentially by a series of "on" and "off" command signals to energize a load, such as an antenna.  The circuitry provides a delay interval between the "off" command to any one switch and the "on" command to the next switch in the sequence.   A simultaneous conduction detection circuit is provided for detecting when two successive switches in the sequence conduct simultaneously.  When simultaneous conduction occurs a signal is output from the detection circuit and input to a multivibrator to increase the duration of the delay interval when such simultaneous conduction is detected.

Abstract: NPN/PNP FABRICATION PROCESS WITH IMPROVED ALIGNMENT          ABSTRACT OF THE DISCLOSURE:         A double diffused, lateral PNP structure is disclosed which may be formed simultaneously with the vertical NPN structure.  The novel feature of the struc-ture is the vertical projection of the N-type base region for the PNP, down through the surrounding diffused P-type collector?and into an N-type epitaxial layer between the collector diffusion and a buried sub-base, an N-type "sub-base", to electrically contact the base.  The N-type epitaxial layer serves as the extrinsic base region per-mitting contact with the surface.  The double diffused base and emitter structure permits a precise intrinsic base width to be formed for the lateral PNP.  Thus, a high performance PNP can be constructed with compatible high performance NPNs on the same substrate.
