Abstract: A water-impervious, non-biodegradable, unitary drainage device with multi-directional rollup capability. The invention features a monolithic “sandwich” construction consisting of planar top and base sheets, set apart by an array of supports that are disposed between and integrally joined to the sheets. Selective and off-set through-cuts, in the top and bottom sheets, impart to the invention the multi-dimensional rollup capability. Rods, optionally hollow, are used as splines to connect two or more of the devices, so that their internal drain channels are in an efficient confluent alignment.

Abstract: A vehicle-mounted, rearward cantilevered frame for holding planar display material such as signs. A sign frame, having a tongue extending from a margin thereof, is made to hold planar displays and present them so that pedestrian traffic, on both sides of the bearing vehicle, may readily view the display. The tongue is made for insertion into a trailer hitch receiver, serves as a securing mount, and is the principal directional and cantilever support for the frame. Guy lines are used to support, further secure and stabilize the sign-bearing frame during vehicle movement by running them from frame tie-points to vehicle hard-points.

Abstract: Optimal ratios of pharmaceutical compositions of &bgr;-1 and &bgr;-2 agonists with their respective antagonists. Safer, more cost-effective drugs for heart and lung therapies are made by combining specific antagonists with their agonists to prevent desensitization of cellular receptors, reducing some of the unwanted side-effects of the agonist drugs alone. Determining the optimal concentration of an antagonist or inhibitor, which is necessary to prevent desensitization, without causing unnecessary and unwanted inhibition, creates a new class of pharmaceuticals. To derive an optimum ratio for a specific composition, a formulative method is provided to detail how competitive antagonists of the receptor should be combined with agonists, in specific proportions, to maximize and maintain receptor response throughout drug administration.

Abstract: A flexible, membranous envelope, in a shroud-conduit-collector configuration for sheathing a catheter. In basic mode, the shroud, which essentially envelops the catheter, is partially disposable in an end of the catheter and is extractable therefrom by manipulation of the user. The shroud joins the conduit, that terminates in an integral, yet separable collector. To cure the basic mode's sole limitation, possible infusion of urethra secretions into the opening of the incipiently inserted catheter, a plurality of leaves are attached by their base margins to the shroud exterior, near enough to the inserted opening that their unattached, leading margins can be folded by interleaving them over, and covering, the opening. By this device, an alternate embodiment avoids the catheter-disposed shroud. Other devices are integrated to facilitate manipulation, as well as to aid in after-use separation, sealing and handling of the collector.

Abstract: Lightweight, insect-barrier garments of reflective/illuminative, moisture-wicking or otherwise breathable covering for protection of a working animal. An ensemble of from one to three garment sections is provided to cover portions of the animal's body that are susceptible to harassment by biting or stinging insects. Illuminative character is present in the invention in modes and at locations that attain the highest profile of visibility, in respect of ambient visibility and the task to which the animal is placed, e.g. daylight/dusk and under saddle, hunting, etc. A bonnet section of the ensemble, integrable with the neck section, is fashioned to stand away from the animal's eyes, thereby protecting its sight by providing a protective insect-resistive guard or debris barrier.

Abstract: A plow blade having two oppositely pivoted/hinged sections that emulate a blade end. The sections alternately occupy a position coextensive to the blade. The sections are coupled to "gait" the movement of one with that of the other. One of the gates can only swing forward of the blade and the other can only swing rearward. When the forward (only) swinging section is thus situated, outflow off the blade is interrupted, i.e., dammed; and, as it returns to the blade coextensive position, it transfers dammed debris to the (coupled) rearward moving section for disposition into the windrow.

Abstract: A frame construct for holding at least one planar mesh or membrane in set-apart relationship from a structural port(a1). Individual frame pieces, top, bottom and sides, are cut to desired lengths and joined to form a glazable frame. Shapes other than of rectangular geometry are obtainable through use of variously angled joiners. Peripheral grooving on both frame faces is receptive of a spline that secures the planar mesh or membrane to the frame, which is then dogged to or otherwise secured in place on/over an opening such as a window, door or the like. Corner elements of the construct also serve as joiners; and, one spline may also comprise a weather strip.

Abstract: A perimeter safety net support assembly of multiple, fixable posts. Each post consists in a stanchion that is fixed by welding, or bolted with braces, for support to a base crosspiece. The base crosspiece is an elongate angle iron that is boltable to a surface for fixation, or constrainable by straps having hooked ends. Two struts are pivotally connected to the stanchion and joinable to each other near a pivotally joined base unit that features fixation design similar to the crosspiece.

Abstract: A cylindrical piston pump with an inlet suction line and outlet discharge port. The pump is capable of lifting chlorine-containing fluid from out a portable container and, with little inducement save gravity, automatically transferring the liquid to a desired, generally lower location. The automatic transfer is effected by flap or analogous valve control; while semi-automatic is effected by rotary or shuttle, manually actuated valves. Outflow is enhanced by gravity, spring return of the piston and/or connection of the discharge line to a fluid entrainment assembly.
