摘要： A pump guard comprising a transparent, flexible, and resilient material including a shielding portion adapted to define a seal chamber in the proximity of a seal of a pump and a pump engaging portion substantially conforming to the shape of a guard engaging portion of said pump. The shielding portion deflects any fluid spraying or leaking from the seal. The pump guard 2 is of unitary construction, requires no mounting hardware, and is easily installable about the seal 16 to define a seal chamber.

摘要： Cross flow diesel particulate traps are disclosed in which a cylindrical canister contains a plurality of individual ceramic trap elements. The canister is provided with inlet openings along one side and outlet openings along another side which respectively communicate with inlet and outlet spaces formed between individual ceramic trap elements. The traps are provided with inlet and outlet plenums which communicate with the respective canister openings for directing exhaust gases through the canister and for collecting the exhaust gases. In one embodiment, the inlet plenum is divided by partitions into zones and a diverter valve directs regeneration gases to selected zones canister regeneration. Ceramic trap elements are disclosed adapted for use in a diesel exhaust gas particulate trap formed with a disc-shaped body of open cell ceramic material with opposite faces terminated by partially surrounding peripheral walls which define inlet and outlet gaps at the respective sides of the element. A membrane layer having a pore size substantially smaller than that of the remainder of the body is formed at the outlet surface of the trap element.

摘要： Described herein are porous ceramic articles comprised of a porous ceramic body portion (of either predominantly open- or predominantly closed-cell porosity) having, integral with pre-selected surfaces thereof, a thin porous ceramic membrane layer which itself may be of open- or closed-celled porosity. Also described are methods of bringing about such membrane layers and such articles. The invention is particularly useful for providing porous ceramic filtering elements, such as diesel particulate traps, wherein the body portion has a predominant open-celled porosity and wherein the porous ceramic membrane surfaces also are open-celled porosity but whose pores are smaller than those of the body portion, as well as for providing articles such as kiln furniture having smooth porous ceramic membrane layers or skins on pre-selected surfaces.

摘要： A low-noise plug valve is formed with a plug in which one side wall of the plug is a grid defined by a plurality of small openings therethrough, which openings lead from the through passage of the plug to a region outside the plug and which grid is movable into partial flow-blocking relation with respect to the valve body outlet, in partially open positions of the plug. The grid creates a back pressure which suppresses the flashing and the formation of cavitation bubbles. The grid openings, in the partially open position of the plug, are in substantial alignment with the direction of flow.

摘要： A plug valve which may be steam sterilized in place, without disassembly or removal from the system, is adapted for use in fermentation processes where the interior surfaces must be sterilized between batches. The plug is provided with internal steam passages which extend longitudinally of the plug and in non-intersecting relation to the through port. The plug casing, in one embodiment, is provided with an inlet for applying steam to the top of the plug for entrance into the steam passages and out the bottom of the plug and through a bottom opening in a casing. In another embodiment, steam may be applied through the bottom opening and into the plug passages, and a steam outlet is provided in the face of the plug through which steam may be extracted through one of the valve casing ports.

摘要： Aggregate-containing products bonded by an aluminosilicate hydrogel are disclosed. A system of two-part mixing and blending of binder components with various granular-like aggregates, modifiers and/or fillers is described in which the resulting compositions are temporarily fluid and formable for short, controllable periods of time but which thereafter become strong, rigid, adherent, erosion resistant composites, requiring little or no external heat supply to achieve full set. The compositions can be formulated for molding on suitable forms or patterns, and may also be prepared in slurry form suitable for spray coating or sealing applications. A wide variety of products can be manufactured of the compositions, including investment molds and cores for foundry use, as well as non-foundry products such as heat and electrical insulators, construction blocks, panels, coating slurries, etc. which may be of essentially solid or foamed (cellular) construction. The novel compositions may be totally inorganic if desired and have advantage in their preparation and use of being non-toxic and environmentally safe, possessing properties of good soundproofing, fire and fluid erosion resistance. The compositions are formulated of readily available, non-critical materials and are correspondingly very cost effective.

摘要： A process for producing a porous ceramic filter for use in the filtering of particulates from diesel exhaust gases, and the filter so produced, in which a foamable ceramic composition based upon an aluminosilicate hydrogel binder is expanded into a self-supporting, open-celled porous body of desired shape by virtue of in situ reaction between components of the composition, and thereafter treated to substantially reduce its alkali metal content and fired to produce ceramic bonds, the process further preferably providing on the intended outlet surface of the filter a thin porous ceramic membrane layer whose pores have an average diameter less than that of the pores within and at other surfaces of the ceramic filter.

摘要： Joining together two materials by a mechanical interlock resulting from "chips" at their interface is disclosed. The chips, composed of one of the two materials to be joined or of a third material are partially embedded into the surface of the first material when that material is formed so as to form surfaces which "overhang" the first material. Thereafter, the second material is formed against the overhanging surfaces of the chips to establish the mechanical interlock. This technique is particularly useful in anchoring a dissimilar material to a polymeric material having poor bondability and/or a high melt temperature, for example fluoropolymers, as illustrated by the forming of a liner for a pump casing, or the like, by rotational molding. In that illustration, small particles and chips are distributed uniformly over the surface of an enclosed mold heated to melt the particles and fuse the chips thereto, and cooled to form a layer with the chips projecting therefrom so as to provide an interlock when a casing is formed against the liner. Other aspects of the present invention include the article of manufacture formed by the above method.

摘要： A filter press comprises a main frame having upper side bars for movably supporting a plurality of plates in horizontally stacked relation. The plates are moved to open the filter press by plate transporting trolleys which are supported on the upper side bars. Light emitters are mounted at one end of the press on each side bar and light detectors are mounted at the opposite end of the press on each side bar and are aligned to receive light from the light emitters. Shutters are coupled to the plate transporting trolleys such that the light from the light emitters is normally blocked by the shutters. The shutters are opened for a brief period of time when the plate transporting trolleys are moved into engagement with one of the filter plates such that plate engagement signals are generated by the light detectors. Control circuitry manages the motion of the plate transporting trolleys in response to the plate engagement signals from the light detectors such that the plates are automatically opened and the trolleys are returned to a park position. The trolleys are also initialized for the next opening operation during travel to the park position.
