Abstract: A massaging table assembly for massaging a user's body includes a table that is positionable at an angle on a support surface for having a user lie thereon. The table has an opening therein. A rocker unit is pivotally coupled to the table and the rocker unit is positioned in the opening in the table. Moreover, the rocker unit is tiltable to a variety of angles with respect to the table. A pair of rollers is each rotatably coupled to the rocker units. Each of the rollers can massage the user's body when the user lies on the table.

Abstract: Preferably, there is defined a “w” shaped exercise bar, a short elongated central shaft that easily comes apart, a pair of hand grip portions disposed on either side of the central shaft, and a pair of removable jump rope handles with adjustable color coded-retractable ropes hidden inside the handles.

Abstract: Preferably, the invention is concerned with a unique “w” shaped exercise bar, a short elongated central shaft that easily comes apart, a pair of hand grip portions disposed on either side of the central shaft, and a pair of removable jump rope handles with adjustable color coded-retractable ropes hidden inside the handles. When together, the bar is ergonomically designed to fit the smaller frames of the age demographic it is intended for (children ages 8 and up), allowing them to perform many exercises in the field of musculoskeletal strengthening, musculoskeletal flexibility, and cardiovascular conditioning. When the bar is taken apart and transformed, the individual pieces complete a pair of light weight dumbbells and an adjustable jump rope designed to fit any child's size from 3 ft to 7 ft tall.

Abstract: A plow assembly comprises a blade, structure attached to the blade and adapted to be attached to a vehicle for mounting the blade to and supporting the blade from the vehicle, and a wing attached to an end of the blade. The wing has a first portion mounted to the blade for translational movement relative thereto, and a second portion mounted to the first portion for rotational movement relative thereto. An actuator has a cylinder and first and second oppositely movable piston rods. The first piston rod and the cylinder operable to move the first portion of the wing relative to the blade, and the second piston rod and the cylinder are operable to move the second portion of the wing relative to the fist portion of the wing.

Abstract: A plow assembly has a blade, structure attached to the blade and adapted to be attached to a vehicle for mounting the blade to and supporting the blade from the vehicle, and a wing attached to an end of the blade. The wing has a first portion mounted for movement along the blade to and between a retracted position and an extended position, and a second portion mounted in fixed relation relative to the first portion at an angle relative thereto.

Abstract: A tree stand for supporting a user between two limbs of a tree at an elevated position above a ground surface includes an outer frame rail and an inner frame rail. The inner rail is telescopingly engaged within the outer rail, thereby allowing the frames to be adjustable along a longitudinal axis. One of the rails includes a plurality of locking features and the other includes a lever having a head adapted to be engaged with the locking features. At least one of the head or the locking features are adapted to be disengaged from the other when the inner and outer frame rails are telescopingly moved outwardly, and at least one of the head and the locking features is further adapted to prevent movement of the rails when the inner and outer frame rails are forced inwardly.

Abstract: A method and apparatus for identifying and analyzing vapor elements, using a preconcentrator collector. The preconcentrator collector collects and preconcentrates chemical vapors to be detected and identified before chromatographic analysis using surface acoustic wave gas chromatograph (SAW/GC) technology. The preconcentrator collector is used in conjunction with a sensor in an SAW/GC detector in the apparatus. A physical parameter associated with the sensor changes in a defined manner upon exposure of the sensor to an unknown vapor, permitting identification of the individual vapor elements. The preconcentrator collector of the invention includes a body portion having an inlet and an outlet, and a stack of collector plates disposed in the body portion. The collector plates are made of a material that is easily micromachinable and easily cleanable, such as silicon, silica or fused quartz.
