Abstract: A depth control structure for an agricultural seeder, having laterally spaced opener structures including pivotally mounted opener beams extending rearwardly and downwardly from the seeder frame to journal openers for vertical motion, provides a depth control wheel adjustably supported forwardly of each opener. Each depth control wheel is journaled in the rearward portion of a body beam pivotally supported in its forward portion on the seeder to extend rearwardly with at least its rearward portion below the associated opener beam. The medial portion of the body carries adjustment structure interconnected with the superior opener support beam to fixedly maintain and adjustably vertically position the depth control wheel relative to the associated opener. The depth control wheels have a cylindrical periphery with substantial width to aid in compacting and conditioning the earth that is to define a potential seed furrow for seed placement.

Abstract: A tool and method for continuous elastomeric band ligation type castration of larger sexually mature animals with an elastic band that must be enlarged by stretching for placement provides an elongate body having a handle at a first rearward end to aid manipulation and an elastic band supporting yoke at a second forward end. The band supporting yoke provides spaced forwardly extending legs for releasable support of the elastic band at two spaced points. Band stretching mechanism carried by the body provides an elongate stretching rod that releasably interconnects one course of the elastic band carried by the yoke at a third point between the two yoke support points to stretch the band rearwardly responsive to motion of an associated compound lever mechanism to enlarge the medial orifice defined by the elastic band sufficiently to allow the band to pass over the scrotal pouch and contained testicular structure of a large animal.

Abstract: A system and particular components are disclosed to measure the reaction time of a user from a signal to start an athletic activity to the start of that activity and the completion time from the start to the finish of that activity. A remote control device responsive to manual input initiates a start signal and a signal to direct that activity toward one or more sensor pads to a user and to a data processor. One or more floor pads sense the presence of the user and signal the user's non-presence to the data processor. One or more sensor pads positioned spacedly distant from the floor pads sense manual contact by the user and signal that event to the data processor. The data processor determines the reaction time and the completion time of an activity from the times of the received signals, annunciates these times in visually cognizable form and stores the data.

Abstract: A seed mat provides an optional lower plastic mesh layer overlain by a lower scrim layer overlain by a seed layer optionally containing biodegradable beneficiating additives overlain by a fiber layer optionally overlain by an upper scrim layer with the fiber layer or upper scrim layer, if present, overlain by an upper plastic mesh layer. The mat is formed on a conveyor by 1) creating the fiber layer on the conveyor; 2) creating the upper scrim layer, if optioned, by placing dry cellulosic tissue over the fiber layer, wetting the tissue, applying vacuum beneath the fiber layer to consolidate the tissue on the underlying fiber layer and drying; and 3) extruding an upper plastic mesh layer on the fiber layer or the upper scrim layer if present.

Abstract: A rotary mixing device provides an elongate powering shaft carrying at a first end portion mixing apparatus formed by a first outer annulus interconnected by quadrantally arrayed first radial elements to the first end portion of the powering shaft, and a second inner annulus spacedly distant along the powering shaft from the first annulus and having quadrantally arrayed second radial elements interconnecting the second annulus and the powering shaft, with each of the second radial elements of the second annulus being coplanar with one of the first radial elements of the first annulus. Elongate peripheral elements extend in quadrantal array to interconnect the first and second annuli with end portions immediately radially outwardly from each coplanar pair of first and second radial elements.

Abstract: A torch disperses an explosive mixture of pressurized oxygen and petroleum gas into the burrow of a rodent for subsequent ignition to destroy rodents in the burrow. The torch provides a configurationally sustaining enclosed dispersement system with an elongate body formed sequentially by a mixer, a gas conduit having a valve to regulate gas passage therethrough and an output nozzle insertable into an entry orifice of a rodent burrow. An ignition system supported on the dispersement system provides an electrically powered spark plug carried in the output nozzle to ignite gases therein. The oxygen and petroleum gases are mixed in determinable proportions and pass through and from the distribution system by reason of gas pressure. The gas channel through the torch is not open to the ambient atmosphere except at the orifice of the output nozzle and a flash guard valve carried inwardly adjacent the output nozzle prevents an explosion in the output nozzle from passing inwardly into the gas conduit of the torch.

Abstract: An invisible decking connector for wood decking structures fastens elongate decking boards to each other in side-to-side adjacency and fastens the decking boards to underlying perpendicularly oriented joists for positional maintenance thereon. The connector provides a medial disk having axially aligned ribbed nails extending perpendicularly from the medial portions of each of its sides. The periphery of the disk defines a slot to receive the head of a fastening screw extending in angulated orientation through an adjacent decking board and into a joist therebeneath. A tool with a body defining a medial hole to receive one of the ribbed nails to aid installation of the fastener by use of a hammer is disclosed.

Abstract: A depilatory aid for use on female external genitalia provides a pair of similar clamping arms pivotally interconnected at first edges, biased to a clamping position, and having opposed lever arms extend from the first edges for opening. The clamping arms are convexly shaped to define an internal space and have second edges for engagement about the genitalia for protection during depilatory process. Portions of space between the peripheries of the clamping arms are covered.

Abstract: A bow type knife provides an adjustment bar between the back and the blade to adjustably determine thickness of sliced material. The adjustment bar is pivotally mounted on two spaced support arms that are pivotally carried in angulated parallel orientation by the back to allow motion of the adjustment bar parallel to the back. An end portion of the adjustment bar proximal to the bow handle carries an adjustment screw that extends in angulated orientation through the bow body and through a nut carried in that body and projecting therethrough for manual manipulation to adjustably position the adjustment bar relative to the knife blade.

Abstract: A cutting tool and associated positioning templates locate and cut rectangular junction box holes in dry wall or similar sheet material forming structural surfaces. Templates defining a medial positioning slot and providing a spaced pair of positioning pins are carried by pre-established junction boxes and surface sheeting material is established thereover with the positioning pins projecting through the sheet material to indicate positioning slot location. The tool provides a body articulately carrying two perpendicular pairs of spaced parallel saw blades that are moved reciprocably by spring biased driving linkage to cut rectilinear holes in the sheet material over the junction boxes. The saw blades have arcuate edges defining cutting teeth of opposite pitch on each side of the arcuate edge of the tool to aid positional maintenance and prevent chatter during cutting.

Abstract: A tool for cutting holes in metal provides a shank defining at one end an arbor releasably carrying a circularly annular cutter that defines teeth at each cutter end which may be sequentially used to extend cutter life without sharpening. The annular cutter defines a plurality of spirally arrayed, inwardly extending flutes and alternating outwardly extending lands on both inner and outer sides to provide cutting edges on both cutter sides at each end. The lands are formed with buttress type sides angulated ten to sixty degrees to a radius passing therethrough steeper spiral arrays of lands and grooves are arrayed in shallower spirals with an angle of up to seventy degrees to the axis of the cutter to allow thinner wall construction in my cutter than in prior cutters. The thinner cutter wall allows definition of more cutting teeth than would thicker walls and the cutter configuration allows definition of stronger, more efficient teeth without gullets.

Abstract: An annular fishing sinker is formed of environmentally compatible materials to dissolve in variable predetermined times in a water environment. The sinker is formed of sand in a matrix of gelatin, particulated cellulosic material that swells in water and unbleached wheat flour with enough water to form a moldable plastic mixture that upon drying is coherent and configurationally sustaining. The components may be varied in relative quantity to provide sinkers that dissolve in from less than one minute to more than twenty minutes. The sinker is attached to a fishing line by tying in such fashion that a knot will not be left in a supporting line when the sinker dissolves. A process is disclosed for forming the sinker by molding with subsequent drying.

Abstract: A flexible bag formed of gas impervious sheet plastic provides a pneumatically sealable chamber that may be evacuated about the peripheral surface of a Christmas tree carried in the chamber. The flexible bag provides an elongate plastic zipper in its upper portion for access for tree placement and removal, a sealable vacuum channel for evacuation, a pneumatically sealable bottom orifice for access to the trunk of a contained tree, plural spaced fastening bands to aid maintenance of the collapsed mode of the bag about a tree and paired opposed handles to aid manual manipulation. The bag may be evacuated for Christmas tree transport, placement and disposal and may be collapsed about the base of a Christmas tree on a surface supporting the tree for storage during Christmas tree use.
