Abstract: A faucet of the single handle mixing valve type. The faucet includes a housing having a domed housing cap enclosing a valve cartridge having an actuating stem movable along a vertical flow-control axis for varying water flow rate, and movable along a horizontal temperature-control axis for varying the temperature. A handle is connected to the actuating stem. A recess extends vertically along the outer surface of the domed housing cap. A releasable stop member is adapted to engage the recess when the handle is moved along the vertical flow-control axis in its cold water only position, and adapted: to release engagement upon application of a horizontal force. A ramp is located along the lower periphery of the domed housing cap outside of the cold water only position and is adapted to prevent the handle from being lowered into a full off position except when in the cold water only position.

Abstract: A CNC lathe jaw alignment system in which the position of the work holding edge of a chuck jaw is accurately located with respect to a work holding tool block mounted on a CNC lathe turret. A laser alignment tool is provided which includes a housing containing a light emitting laser module powered by a battery and an on/off switch. This laser module is used to project a laser beam onto the mounting face of a CNC lathe chuck to form a red target dot at the diameter of the workpiece. The laser alignment tool allows the lathe operator to visually see the workpiece diameter on the chuck as a red target dot generated by the laser module. This red target dot allows the operator to substantially expedite the process of accurately attaching jaws to a CNC lathe chuck in preparation for machining processes.

Abstract: An archery arrowhead having a body with a substantially triangular base and truncated triangular sides to form a substantially truncated triangular pyramid. A cutting blade is formed at the juncture of adjacent truncated triangular sides. Each of the cutting blades have a leading end and a trailing end. The leading ends of the cutting blades terminate in needle points. The width of the blades at their trailing ends is greater than the width of the blades at their leading ends. The leading end of the body located opposite the base has a concave recess formed therein. A concave flute is formed in each of the sides of the arrowhead.

Abstract: An adjustable work stand for motorcycles includes a platform and platform support means. The platform support means includes left and right vertical support members adapted to be adjustable upwardly and downwardly. Upper and lower horizontal support members extend between the vertical support members. The platform is pivotally attached to the upper horizontal support member. A vertically adjustable platform support arm extends between the lower horizontal support member and the underside of the front of the platform. A stand support arm extends rearwardly from one of the left and right vertical support members, the forward end of the stand support arm being pivotally connected to the vertical support member, the rearward end of the stand support arm adapted to contact the same surface upon which the vertical support members rest.

Abstract: A sliding door grab bar opener for opening and closing a sliding door. The opener includes outside and inside tube members, each having first and second ends. The inside tube member is positioned within the outside tube member and is adapted to slide from a fully retracted configuration with the first end of the inside tube member being located adjacent the first end of the outside tube member to a fully extended configuration with the first end of the inside tube member being located adjacent the second end of the outside tube member. First and second end stanchion members are attached to the outside and inside tube members adjacent their first and second ends, respectively. A middle stanchion member is attached to the outside tube member adjacent its second end. The stanchion members are adapted to be attached to the frames of the sliding door panels by fastener means.

Abstract: A golf putting training device including a circular target having a substantially flat body having substantially parallel upper and lower surfaces. A bumper formed of rubber or an elastomeric polymer is attached to or integral with the peripheral edge of the target. The upper surface of the target has a plurality of substantially equally spaced-apart primary lines extending from the center to the peripheral edge to form a lane between each adjacent pair of primary lines. The width of each lane is substantially the width of a regulation hole. The circular target can be divided into partially circular targets having a 90 degree, 180 degree, or 270 degree circumference.

Abstract: A wheel assembly for use on wheeled luggage usable as a seat A seat cushion is located on the upper end of the luggage. The wheel assembly includes a wheel housing having a brake shoe located within the housing. A wheel carriage is positioned within the housing. The wheel carriage rotatably supports a wheel having a rolling surface. In response to a traveler sitting on the seat cushion, the wheel carriage has means adapted to allow the wheel to move from a first position where the rolling surface of the wheel is not in contact with the brake shoe to a second position where the rolling surface of the wheel is in braking contact with the brake shoe, and to cause the wheel to move from the second position to the first position upon the traveler arising.

Abstract: A portable bar including an ice chest, a removable tray, and a plurality of beverage containers attached to the upper surface of the tray. The ice chest has a rim located on the interior thereof adjacent its upper perimeter edge. The removable tray is adapted to rest on the rim with either its upper or lower surface facing towards the interior of the ice chest. Each of the beverage containers has a manually operated pump dispenser removably attached thereto and providing a lid thereto. In its transportation and storage configuration, the upper surface of the tray and attached beverage containers face downwardly towards the interior of the ice chest. In its service configuration, the upper surface of the tray and attached beverage containers face upwardly.

Abstract: An alignment mechanism for aligning the ball with the socket of trailer hitch comprised of a ball portion attached to a towing vehicle and a socket portion attached to a trailer. The alignment mechanism has an alignment body that is cylindrical-shaped having an outer wall, an upper face, a lower face, and a circular opening passing through the center of the body. The circular opening has a diameter that is substantially the same as the diameter of the socket. The upper face has a U-shaped slot and a wedge-shaped slot, the slots being adapted to receive the outer end of the socket portion. The lower face has a truncated conical surface extending upwardly and inwardly between the outer wall of the alignment body and the circular opening. A stop member extends downwardly from the truncated conical surface.

Abstract: A composition including an aqueous solution of calcium polysulfide and an amount of a precipitation preventing compound effective to reduce or eliminate precipitation of the calcium polysulfide at low concentrations. The precipitation preventing compound is selected from the group consisting of sodium hydrosulfide, potassium hydrosulfide, sodium sulfide, and potassium sulfide. A method of reducing or preventing precipitation of calcium polysulfide added to the water in an irrigation system by first injecting the precipitation preventing compound into the water in an amount effective to reduce or eliminate precipitation of the calcium polysulfide at low concentrations. Sodium methyldithiocarbamate can be added to the calcium polysulfide/precipitation preventing compound solution without any substantial precipitation.

Abstract: A method and apparatus for placing a protective sheet over a load. The apparatus includes a chassis having outer and inner wheels adapted to allow the chassis to traverse along a horizontal path of motion. A mandrel support beam is attached to the chassis adjacent its inner end, the outer end extending beyond the chassis with its longitudinal axis being substantially perpendicular to the horizontal path of motion of the chassis. A mandrel is rotatably attached to the chassis, the outer end of the mandrel being rotatably supported by the mandrel support beam. At least one of the inner wheels of the chassis is in contact with the mandrel adjacent its inner end in a manner adapted to cause the mandrel to rotate upon rotation of the wheel. Pockets located along the mandrel allow the sheet to be releasably attached for winding up onto the mandrel.
