Abstract: An object is splatter painted by painting the object with a basic paint, coating the painted surface with a clear polymer, rotating and heating the object, applying paint to the clear polymer coat by a slinging action while the clear polymer is still tacky to receive the paint from the slinging action and have the slung paint become imbedded in the tacky polymer coat and merge with the polymer to provide a smooth finish, allowing the slung paint to completely dry, and applying a coat of clear polymer over the completely dry surface. The paint can be slung from a pointed rod which has been dipped in a paint supply.

Abstract: An expandable rivet assembly for attaching objects, especially when using bone. The assembly includes a rivet and puller where the puller is pulled to expand the rivet. A stop is provided in the rivet to set an upper limit to the expansion of the rivet by the puller. This rivet is useful in material of varying density, and has slots on the side and a contoured surface to initiate bending at a desired location.

Abstract: A location monitoring system is provided having a radio frequency transmitter for a person or object and radio frequency receiver for someone to monitor movement of said person or object, said receiver sounding an alarm at a predetermined time after failure to receive a signal. The transmitter is made having an intermittent transmitted signal and the receiver is made having an off-timer to coordinate with said intermittent signal, said off times saving battery power. The radio frequency receiver has an electronic switching means controlled by said radio frequency transmitter for sounding an alarm. An antenna is located in part of the carrying strap of said transmitter. The radio frequency transmitter can have various devices for sounding the alarm.

Abstract: A distress flag for a vehicle with the flag being made of foldable material. The distress flag is positionable in use over the top edge of a window of a vehicle so that it can hang downwardly, displaying a printed message. Magnetized weights are fixed to edges of the distress flag to pull it down to properly display the message in use. For storing the flag when not in use, a pocket is fixed to the distress flag so that the flag can be folded into a compact form and placed within the pocket.

Abstract: A cover member and replacing tool for disconnecting a cover from a sprinkler and removing it and also for replacing a cover on a sprinkler and connecting it. The tool has a handle with a cap member for placing over a cover. The cap member cooperates with radially placed outstanding lugs on the cover to rotate it in one direction to disconnect it and in the opposite direction to connect it. The cap member has projections extending therefrom for engaging surfaces on the cover for lifting it. The projections are movable for disengagement from the cover after the cover has been replaced and connected.

Abstract: A sprinkler having a nozzle for directing a desired flow of water therefrom wherein the nozzle is mounted in a rotatable nozzle housing. The nozzle has two flow passages therethrough, a primary nozzle passage and a secondary nozzle passage, the flow through the primary nozzle passage being directed therethrough for long range coverage, and the flow through the secondary nozzle passage being staggered, or off-set, for short range coverage.

Abstract: High performance sail craft operate in high apparent wind velocities which induce high aerodynamic loads into the said surface. This invention provides a light weight sail construction that resists deformation of the sail surface caused by high aerodynamic loads. The sail construction consists mainly of ribs permanently affixed to the sail surface to stretch the sail material. Each rib in the sail provides the required amount of stretch in the sail material to eliminate stretch folds in the sail surface. Each rib in the sail has the stiffness or resistance to flexure varying along its length to control the sail surface curvature thereby providing a low drag airfoil for high speed sailing. A double surface sail construction is provided wherein each sail surface consists of the aforemention sail construction. A parabolic nose forms the leading edge of the double surface sail to provide smooth air flow entry. The rearward end of each sail surface is joined to form the sail trailing edge.

Abstract: An improved ram air, multi-cell wing type canopy with suspension flares has its lower surface shortened to provide an enlarged inlet; one flare is directly attached to its upper surface. A modification has a channel provided to direct air flow over the upper surface. Scoops under the lower surface at the rear end provide protection against the canopy uncontrollably folding under.

Abstract: A gear driven oscillating sprinkler head has a gear train transmitting rotational drive from a drive motor to the oscillating sprinkler head with a shifting drive mechanism which includes alternately engageable driving devices providing oscillation. An over-center spring maintains the direct driving engagement bias for a driving device on each side of a center position of the shifting drive mechanism. An over center spring carry device places a bias against the shifting drive mechanism to move the shifting drive mechanism over its center position once a driving device has become disengaged from driving the sprinkler head, during a reversing action, so that the over-center spring now biases the shifting drive mechanism in the alternate driving engagement position. Adjustable arc of oscillation includes adjustment to full circle rotation.

Abstract: A rotary mower blade for mounting on a power driven rotary lawn mower and designed for improved durability, performance, and safety. The blade is formed of solid metal in the conventional manner, but has an added elastomeric protective shielding applied to each uplifted flange area. The shielding of a layer of polyurethane can be mounted in a recess in the surface of the blade.

Abstract: An adjustable arc spary nozzle is set forth which includes a cylindrical member with an arc set member therein to provide adjustable flow directed into a spray deflector, either stationary or rotary. Modifications are presented to obtain varying effects to the flow. The spray deflector is shown: (1) fixed to the cylindrical member; (2) fixed to the arc set member; and (3) rotating.

Abstract: A drain tube for implanting in an ear drum is formed having a center body with a circular flange on each end with a cover member over each flange forming a chamber therewith. The cover members have openings therein and the center body has drain holes therethrough having a high L/D ratio to permit proper drain flow from an ear and prevent undesirable flow into an ear. A tab is used for insertion and a method of forming the drain holes is set forth wherein grooves are placed in the surface of a large opening and the grooves closed to form drain holes by a plug placed in the large opening.

Abstract: A measuring device and method for use in total hip replacement. A measuring member or arm is pivotally attached to two Steinmann pins in the ilium and a single Steinmann pin is placed in the femur next to the measuring arm. The measuuring arm is made level by the use of a bubble level at a predetermined position and measurements taken to locate the femur with respect to the ilium. This procedure is done after the hip replacement, and measurements taken again. The results are compared to see if the ilium and femur are properly positioned or need adjustment.

Abstract: A hand-held surgical rotary impact tool and instrument extension for removing artificial hip, or acetabular, cups of a hip joint by rotating the cup a predetermined number of degrees. This rotational limitation is provided by a pin and arcuate groove connection between a fixed housing and rotatable shaft. While instrument extensions are sized to allow for different acetabular, or hip, cups, the cup engaging end can have radially adjustable pins for permitting a variable diameter for connection to a cup.
