Patent number: 6742276Abstract: A plastic suit drying system comprises a drying chamber with an air warmer, and a mobile dryer rack. The mobile rack has a wheeled air plenum base, a number of drying positions (each comprising three perforated air pipes protruding up from the base), and a flanged air inlet in the back of the base that mates with a connection flange in the drying chamber. Through this flanged connection hot air is forced into the base/plenum and then into the perforated pipes. For use, wet plastic suits are placed upside down on the drying positions. Then, the mobile rack is rolled into the drying chamber so that the rack's flange mates with the drying cabinet's connection flange. Next, the drying chamber doors are closed, and the drying cycle started, during which heated air is blown into the mobile rack plenum and up into the air pipes extending into the suits.Type: GrantFiled: April 15, 2003Date of Patent: June 1, 2004Assignee: UniFirst CorporationInventors: Kent D. Anderson, Les Case, Michael R. Fuller, David K. Welcher, II, Richard F. Tardy

Patent number: 6655701Abstract: An inflatable tube ski vehicle with steering mechanism comprises an inflated, torus-shaped tube or bladder and a ski insert disposed in the central opening of the bladder. The ski insert may be dish-shaped, or it may partially wrap around the top and/or bottom of the bladder. In either case, the ski vehicle has a steering/braking mechanism comprising left and right lever arms pivotally attached to and extending down through the ski insert. To turn, a rider simply pulls on one of the lever arms, causing a lower portion of the lever arm to extend past a bottom of the insert. To brake, both arms are pulled simultaneously. Because the ski vehicle is round and because the weight of the vehicle and rider are largely uniformly distributed over the center of the vehicle, a pivot or fulcrum point occurs directly under the rider's seat, affording a significant degree of control.Type: GrantFiled: July 25, 2001Date of Patent: December 2, 2003Assignee: Roto-ski, Inc.Inventor: Barry G. Oberpriller

Patent number: 6547678Abstract: A vortex generating golf ball dimple for producing a turbulent boundary layer on the surface of a golf ball during its flight is a composite of a plurality of overlapping smaller concave sections. Preferably, the dimple is a plurality of peripheral spherical sections overlapping a central spherical section to form a ridge-like polygon. The polygon, the top edge of which lies below the outer edges of the dimple, acts as a vortex generating structure within the dimple concavity for producing the turbulent boundary layer. Each pair of opposite or near opposite sides of the polygon has a common cross-sectional shape or structure. The aerodynamic characteristics of the cross-sectional structure are such that the turbulent boundary layer is formed about the dimple at even relatively low velocities without any unnecessary interference being produced at high velocities.Type: GrantFiled: October 15, 2001Date of Patent: April 15, 2003Inventor: Gilbert Barfield

Patent number: 6427497Abstract: A wall-mounted locking system for firearms comprises a wall-mounted base plate having hinged primary and secondary latch doors. A breech hook is connected to the base plate. The primary latch door carries a locking mechanism, which is dimensioned to pass through a hole or cut-out provided in the secondary latch door. Additionally, a barrel ring or muzzle hook is wall mounted above the base plate. A firearm is held against the base plate via the breech hook, which engages the firearm's ejection port and prevents the firearm from being loaded with ammunition. The barrel ring or muzzle hook prevents the firearm's barrel from being moved laterally. The firearm is secured via closing the latch doors and locking the lock.Type: GrantFiled: April 4, 2000Date of Patent: August 6, 2002Assignee: O.F. Mossberg & Sons, Inc.Inventors: A.

Patent number: 6427357Abstract: A marking device for a CNC machine tool or the like comprises a tubular body capped at either end with top and bottom plates. A main shaft extends down through the top plate along the central axis of the body, and is rotatably held in place by upper and lower bearings. A cylindrical cam having one or more cam lobes disposed on an underside thereof is attached to the main shaft within the body. A guide extends through the bottom plate and slidably supports a spring-biased stylus, an upper, anvil end of which normally tracks along the underside of the cam, and a lower, marking point end of which normally lies just within the guide. When the main shaft is rotated, e.g., by being operably connected to the machine tool's spindle, the cam also rotates, causing the cam lobes to strike the anvil and drive the stylus axially downwards through the guide and into a part or work piece. To create a complex pattern, the machine tool sets the spindle to rotate at a constant rate.Type: GrantFiled: July 26, 2000Date of Patent: August 6, 2002Inventor: Thomas W. Piper

Patent number: 6331162Abstract: A pulse wave velocity measuring device generally comprises first and second photoplethysmographic transducers or probes electrically operably connected to a computer. The transducers are positioned on a patient's back to record pulse waveform information at two locations along the descending thoracic aorta. Additionally, the patient's ECG is recorded. Once the pulse waveforms and ECG waveform are recorded, noise or artifact ridden data is excluded, and the pulse waveforms are signal averaged using the ECG data points as fiducial references. Then, the signal averaged pulse waveforms are analyzed (again, with the ECG data providing fiducial points) to determine the foot of each waveform and the foot-to-foot transit time between the two transducers. Pulse wave velocity is then determined by dividing the distance between the transducers by the foot-to-foot transit time.Type: GrantFiled: January 28, 2000Date of Patent: December 18, 2001Inventor: Gary F. Mitchell
