Abstract: A slipper sock having a rubber sole liner. The lining is formed by embedding the sock within uncured, liquid latex rubber. The liquid rubber is prevented from embedding a central zone on the sole of the sock, but embeds fabric of the sock at the periphery of this zone. This is preferably accomplished by spraying a coagulant upon the sole of the sock, which causes immediate, localized curing of the uncured latex which then cannot permeate through the sock fabric. The liner thus is securely bonded to the sock. The sock has a sole comprising fabric unencumbered by rubber, thereby presenting a fabric material to the sole of a wearer's foot. The liner protects the fabric sole from abrasion and protects the wearer's foot from sharp objects and extreme temperatures, while the liner remains physically separate and apart from the fabric sole.

Abstract: An exercise bar for use with standard weight machines employing exercise bars. The bar is vertically hinged in the center, so that it is usable not only for pull down exercises, but also forms a vee which is compressed during pectoral exercises. The two sides of the vee are geared together, so that the vee opens and closes symmetrically, both arms being forced to move the same amount. An adjustable spring assembly attaches to the bar for selectively varying resistance for the pectoral exercises. A brace contacts the user's forearm, so that the user applies a force countering the tendency of the bar to incline responsive to being drawn downwardly. The bar is configured to include a relief in the center, so that it can be pulled down past the user's head, while avoiding interference with the user's neck. The novel exercise bar is rugged, uncomplicated, increases the number of exercises which can be performed, and can be retrofit to a standard weight machine.

Abstract: A small batch mixer particularly suited for preparing small quantities of mixture blends dry powdered material with an aggregate and a liquid. The ingredients may be cement, sand, and water. The batch mixer has two screw augers. The first auger feeds dry mix into an elongated mixing chamber of constant diameter. The second auger mixes the dry and liquid mix constituents, and conducts blended mixture to a discharge port located at the end of the elongated mixing chamber. The blade of the second auger is formed in three sections. In respective order, these sections include a first section wherein the blade is configured as a screw auger; a second section wherein the blade has intermittent gaps, thereby forming paddles pitched to urge the mixture onward to the third section; and a third section which, like the first section, includes a blade configured as a screw auger. The liquid is metered by a valve controlled in accordance with the feed rate of the solid constituents.

Abstract: A repair apparatus for tire punctures is operable upon a damaged tubeless tire in situ and includes a hollow probe initially containing a rubber boot disposed in a collapsed condition but subsequently automatically unfolding when urged into the tire interior by a plunger rod in the probe. A stem integral with a circular main body of the rubber boot is connected to the plunger rod by a flexible tether that serves to retain the unfolded boot juxtaposed the puncture point inside the tire while a drive rod forces a measured amount of rubber bonding fluid through the probe to sealingly secure the boot. Alignment and retention of the probe and drive rod is facilitated by a mounting unit secured to the tire by adjustable attachment elements clampingly engaging the rim of the wheel mounting the tire while threads on the probe and drive rod cooperate with tapped bores in the mounting unit to permit controlled advancement and retraction of the probe and drive rod.

Abstract: A spinning ornamental incandescent bulb cover has a shade portion and a spinning turbine vane portion formed from a single flat sheet of flexible material. Convective air currents, generated by the heat of the bulb, are passed over the turbine vanes to rotate the entire shade. No internal or external support frame structure is required for the shade or the turbine vanes. The turbine vanes meet at a common central point at which there is located a downwardly directed needle which rides in a bearing to allow rotation. The bearing is provided by a small cup held by a spring which engages the bulb. The needle point support also provides for automatic vertical alignment of the shade regardless of the orientation of the needle. The overall shape of the shade is frustoconical so as to converge the convective air currents and increase their velocity relative to the turbine vanes. The turbine vanes have a varying angle of attack in the radial direction for increased efficiency.

Abstract: An anchor for a dental implant, having a compact cavity for receiving the post of a post and core, and a tapered threaded end having tapered, self-tapping threads. The cavity is configured to have flat walls forming a hexagonal or other polygonal interior surface. This interior surface also has screw threads superimposed on the polygonal surface. The anchor is thus of reduced axial length than prior art anchors having threads and polygonal surfaces not superimposed. The tapered threads formed on the tapered threaded end engage different areas of bone tissue. Since bone tissue may not be homogeneously strong and resilient, this arrangement helps assure that some threads will engage strong, resilient bone tissue. This threading preferably comprises buttress type threads. A pitched relief groove extends across all convolutions of the external, self-tapping threads formed on the tapered end. These self-tapping threads are buttress threads.

Thus as the disk spins, the tool carrying shaft is moved in a reciprocal manner, with power being applied in the stroke in both directions. A pivotable cutting hoe is attached to the tool carrying shaft in the preferred embodiment.

Abstract: An improved replacement ladder rung/pulley construction is disclosed wherein a rotatable rod, mounted on bearings and extending substantially completely from one side of the ladder wall to the other, is located within the rung. The rung has a cutout portion proximate its center, which allows a rope to be passed therethrough and over the rotatable rod. The rod thus functions as a pulley and obviates the possibility of the rope sliding off and becoming jammed if the pulling force is exerted from one side or the other.

Abstract: A net for covering raked leaves and similar plant debris. The net is bounded on two sides by two telescoping poles. A chain links the ends the ends of the two poles, and a second chain links the remaining ends of the two poles. The net is thus weighted to hug the ground and resist displacement by the wind. The net, being flexible, accommodates leaf piles of different volumes and dimensions. The telescoping poles and flexible chains both hold the net down by gravity, and also influence the overall configuration of the net. Opposing sides of the net attached to the poles remain straight, although of variable length due to telescoping. Opposing sides of the net attached to the chains are reconfigurable due to flexibility of the chains. The net is useful for immediately covering collected leaves, and preventing dispersion by the wind. Also, the net is suitable for longer term use in composting. Rings attached the poles enable stakes to secure the net in place for composting or other long term uses.

Abstract: A pry bar tool for removing step flashing from a building during roof replacement or like service. The tool is configured to receive a nail on right and left sides, at any of a number of possible nail pulling notches or grooves. The two ends are offset differently, so that a variety of pulling positions is offered. Enlarged heads for receiving hammer blows enable the tool to be tapped while maneuvering to remove a nail from the flashing. The novel tool is able to remove nails expeditiously from flashing without distorting or destroying the flashing, so that it is reusable.
