Abstract: Apparatus and method for hydraulically adding a powderous substance to a liquid such as a water system, wherein the substance container is provided with a screened lower zone supplied with a liquid sprinkler device, the device being useful to spray liquid on the interior surface of the screen provided for essentially dissolving the powderous particulates which are present at and pass through the screen or filter provided; the slurry produced can be delivered to a local or remote point.

Abstract: Improved ionizing structure for ambient air treatment wherein the structure incorporates an ionizing needle directed in the direction of airflow; the needle is negatively charged to produce an electrostatic field, preferably pulsating, whereby to ionize air constituent molecules, lint, and other entrained constituents, allowing the latter simply to precipitate out of the air and fall to the ground or floor beneath; in such manner ambient air within a room enclosure, for example, is cleaned for maximizing occupant enjoyment as well as for health and other reasons.

Abstract: Suspended seating apparatus comprising a chair supporting structure with an extensible cantilever arm and adjustable base structure for balancing the cantilever effect and also for accommodating one or a pair of suspended seating arrangements.

Abstract: Apparatus and method for hydraulically adding a powderous substance to a liquid such as a water system, wherein the substance container is provided with a screened lower zone supplied with a liquid sprinkler device, the device being useful to spray liquid on the interior surface of the screen provided for essentially dissolving the powderous particulates which are present at and pass through the screen or filter provided.

Abstract: Suspended seating construction comprising a chair supporting device having L-shaped structure constructed for selected mounting to the wall and associated cabinetry; a mount to the cabinetry supports both the swing arm accommodating the suspended seating and additionally precludes failure of wall mount structure incorporated in the device.

Abstract: Mine strata support structure and components in a mine truss and including a mine bracket and a connector, the latter preferably being in the form of an elongated stirrup; the mine bracket, stirrup and associated structure are constructed and dimensioned such that the stirrup may be brought into retentive engagement with the bracket and not slip inadvertently out of engagement; this can be produced through the employment of a depending projection which vertically depends from the bearing plate of the bracket, such projection serving with the body of the bracket to supply an access path for stirrup installation, the projection deterring excess rearward travel of the stirrup whereby to maintain bracket-stirrup inter-engagement, and thus truss-integrity, even during conditions of mine strata shock.

Abstract: Anchor structure suitable for retentive placement in a borehole, whereby to anchor an elongated anchor bolt in a fixed position within such borehole; the anchor structure is designed for mechanical and also setting-medium system securement within the borehole, the mechanical structure utilized being radially expansive and, by such means, offering an immediate anchor by which the setting-medium used is given time to set up.

Abstract: Cable bolt structure, related components and method for achieving desired ground control of mine roof strata in a dynamic manner; a sustained transverse enlargement, of particular design, of a portion of the cable bolt employed coacts with a tubular member to elastically expand the latter, whereby to generate a heightened frictional resistance as between the cable bolt and such tubular member, for achieving desired strata control.

Abstract: Cable bolt structure, related components and method related to the support, in active and passive modes, of mine roof strata for achieving desired ground control.

Abstract: A threaded bar construction and bar stock and nut combination useful in the mining industry and also in the concrete industry; the bar stock is provided with raised thread segments which appear only on one side of the elongate bar employed, so as to provide for marked reduction in manufacturing costs without detracting from the pull strength or tensioning parameters desired.

Abstract: Ionization systems in and for laundry dryers and other contexts, whereby to neutralize static electricity build-up and acidic conditions, and thereby create environmentally friendly systems for drying clothes and other fabrics, generally prolonging fabric life, reducing particle and lint entrainment, and also reducing if not eliminating acidic conditions in dryers and other environs.

Abstract: A support sling, useful in the mining industry, for example, for supporting overhead loads such as mine roofs; the sling includes a pair of generally coplanar anchor lengths, sometimes called anchor bolts, having inwardly directed ends mutually facing each other and which, thus, are essentially coaxial; a similarly coaxial take-up coupling structure secures the ends and is constructed, either in active or passive mode, to restrain loads, acting under the force of gravity, from dilating downwardly to extreme conditions, and this in a manner as not to allow for the generation of serious force couples in the sling.

Abstract: Mine roof support systems, components and method, for supporting, whether in active or passive mode, mine roof strata; first and second, mutually spaced series of brackets are supplied for mounting to opposite sides of a mine roof span, and one or more cable assemblies are looped about such brackets and secured to the mine roof strata, such cable assemblies also being provided with take-up means: the invention is suitable and effective for supporting mine roof strata at various, desire mine locations.

Abstract: Beverage delivery structure including a counter top with support structure and also an ice chest conveniently supplied proximate the counter top; the ice chest is provided with an insert structure containing a beverage delivery pumping unit and, thereabove, a well for receiving a series of beverage bottles; a primary source of a beverage constituent as well as beverage delivery structure are coupled to the intake and output ports of the pumping unit.

Abstract: A turf and garden tool implement useful in extracting weeds as well as severing the branches of small plants, bushes, small trees and the like; the tool includes an elongate rod member provided with a handle and a foot step, with the lower portion of the rod member being supplied a tool, generally referred to as a root trap tool, which is curved and hemi-conical in configuration, the leading edge being provided with serrations for suitable cutting purposes, and the upper edge of the tool being arcuate, upwardly angulated in a curvilinear manner, and is provided with a sharpened edge margin for effecting branch removal.

Abstract: A trailer hitch for securement to the medial step portion of the rear bumper of a towing vehicle such as a pickup truck; the trailer hitch includes a mount member which is mounted and also keyed against rotation to the step of the bumper; structure is provided for coupling a ball hitch to the mount in a manner that the same is adjustable for ball height as well as effecting detachment of the ball and its associated structure from the support mount affixed to the bumper.

Abstract: A table construction suitable for fabrication in elemental forms preparatory to break-down shipment and on-site assembly, when desired, and including suspended seating construction; the support structure of the table top incorporating the suspended seating takes the form of a hub and spoke construction of telescoping nature, the hub generally comprising a cross and the spokes telescoping therewith being provided with elements for attaching the support structure to the underside of the table top preparatory for table erection.
