Abstract: SILICA-CONTAINING POROUS BODIES                   OF CONTROLLED PORE SIZE                 Abstract of the Disclosure This invention relates to the preparation of silica-containing particulate materials and monolithic structures exhibiting high porosity with exceptionally uniform pore size.          The bodies are produced through gelation of aqueous alkali metal silicate and/or colloidal silica solutions, optionally contain-ing dispersed particulate phases, with organic reagents followed by a leaching step.  Uniformity of pore size is achieved through careful control of such variables as the ratio of alkali metal silicate to colloidal silica solutions, the concentration of silica, the amount of dispersed phase employed, and the like.          Hence, for example, a porous silicate body having very closely-controlled, small-sized pores would be eminently suitable for such applications as catalyst supports for air pollution control, filtration devices for gases and/or liquids, acoustical materials, and chromatographic supports.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to an accelerator for charged particles which comprises a vessel adapted to enclose a stream of charged particles along a preselected track.   A magnetic field travelling in a preselected direction relative to each point of the track with the magnetic flux vector of the field transverse to the track at all points is generated, thereby setting the particles in motion along the track with a velocity which has a predetermined relation to the velocity of the travelling field.   The invention utilizes, in a particle accel-erator, specific dynamic effects caused by the unidirectional entrainment of both positively and negatively charged particles of a plasma by a travelling magnetic field.

Abstract: ABSTRACT:         A method of defining, a fine line low resis-tivity pattern in a layer of high resistivity poly-crystalline semiconductor material present on an insulating layer on the surface of a semiconductor body by lateral impurity diffusion under the edge of a masking layer present on the polycrystalline semiconductor material. The undiffused polycrystalline semiconductor material mayor may not subsequently be removed depending upon the application of the method.          In one form the fine line pattern is selectively re-moved to leave a precisely defined aperture of narrow width in the polycrystalline layer. In one specific embodiment described the method is employed to define high impedance load transistors in a silicon gate integrated circuit. In another specific embodiment described the method is employed to define a compact crossing connection between a polycrystalline silicon line on an oxide layer and an underlying diffused con-nection region in a silicon gate integrated circuit.

Abstract: ABSTRACT OF THE DISCLOSURE         A pollution control system to reduce the presence of fine aerosol particles in stack gases from the manufacture of glass fiber wool-type products.  After larger particles are removed from the forming fan gas, massive quantities of water are injected into the fan intake.  The aerosol particles are agglo-merated by impact with the air-borne water droplets and the wet surfaces of the fan.  The larger, coalesced or agglomerated particles are more readily susceptible to inertia-type separation from the air by either the action of the fan or in a later separation operation.  It has been found that more than 40% of the fine, aerosol particles introduced to the fan can be removed in this way.  Further, the re-circulating process water can be utilized, reducing or eliminating the consumption of fresh water and maintaining the normal process water system of the manufac-turing operation.

Abstract: ABSTRACT OF THE DISCLOSURE         Treating natural water to retain desired qualities and removing undesirable organics and other contaminants, while at the same time killing microorganisms such as bacteria and virus, is an objective of this invention.  The process and apparatus described herein utilize an anion exchange resin in the bicarbo-nate form to remove anions such as chloride, sulfate, nitrate in order to precondition the water to be treated so that silver ions to be subsequently added to the water will be effective as a bactericide, virucide.  After preconditioning, the water is fur-ther treated in a media consisting of an activated charcoal bed having silver salt(s) whose solubility product results in a sil-ver ion concentration in water in excess of 50 µg/1 impregnated and adsorbed on the activated charcoal.  The silver salt(s) pre-vents: 1)  bacterial growth on the activated charcoal bed, thereby self-sanitizing the bed of charcoal, and 2)  imparts residual silver ions to the water in and passing through the media The residual silver ions in the water are greatly in excess of the 50 micrograms per liter (50 µg/1) allowed by the Environmen-tal Protection Agency (EPA) Standard for Drinking Water,  The high concentration of silver ions in water (800 µg/1 and greater) has been found to be much more effective as a bactericide, viru-cide (i.e., biocide) since it is effective in a matter of minu-tes as opposed to hours or days for silver ions to be effective at a level of 50 µg/1.  After the silver ions are added to the water and the resulting water containing the high concentration of silver ions is retained for a holding time of a few minutes, the silver ion level is reduced to 50 µg/1 or less by a second anion exchange resin in the chloride form.     The ion exchange resins in both the bicarbonate and chloride forms are also self-sanitized by means of a silver salt wash while being regenerated in the bicarbonate and/or chloride form.          Before pretreatment of the input water, suspended so-lids can be removed by conventional filters and the water may be further treated after the silver ion level is reduced to allow-able standards.  Further treatment of water following the above described invention with activated charcoal which is self-sani-tized with silver salt(s) which release little or no residual silver ions is also contemplated by this invention.

Abstract: A B S T R A C T    An improved calibration mechanism is provided for use on a pressure switch having an adjustable, spring biased plunger arrangement for controlling the pressure level required to actuate the switch. The mechanism includes a support bracket, a cam rotatably supported by the bracket and a plunger adjustment lever, including a cam follower in engagement with a surface of the cam. The support bracket defines a guide slot into which the cam follower extends, transverse movement of the cam follower being limited by the guide slot. The cam surface defines a range of pressure settings between the normal low and the normal high as well as a switch reset position adjacent the normal high setting position. The guide slot includes a stop surface which engages the cam follower when the cam is turned to the reset position, and the configuration of the cam, plus the engagement of the follower and the stop surface, prevents further turning of the cam. This arrangement provides a positive stop for the cam rotation and makes it possible to eliminate corners on the cam which might interfere with the wiring.
