Patent number: 6384309Abstract: A clarinet and a flute of the woodwind family are provided with a case that holds the instrument firmly in position. The part of the case that opposes the instrument has a plurality of projections to close and hold closed all normally open keys when the case is closed, so that pressure on all of them is similar, so that there will be no malformation of keys or operating members. Thus, all keys will open and close as they are supposed to and the instrument will remain in good playable condition for a very long time. Although the invention is explained with regard to clarinets and flutes, it applies equally to all members of the woodwind family.Type: GrantFiled: September 8, 1999Date of Patent: May 7, 2002Inventor: Larry L. Lellingson

Patent number: 6318921Abstract: A plurality of pens or other marking implements is provided. They are set forth as a minimum of two, but by the simple technique of altering the reservoirs, the colors can be substituted almost infinitely. There are two for each implement, and these can be multiplied in two by changing the ink devices. Other changes can be made by duplicating the implements or writing pens, which come in pluralities of two. Adjacent pairs are locked together by shaping of the base, and the pens can be duplicated in initial savings by the colors chosen, and the number of pens can be duplicated depending upon the shape of the devices which are made to be interlinked by joining of the bases, and by the self-return of the base station from which the pens originate, the pens being joined to the base station by flexible links of indeterminate length.Type: GrantFiled: March 8, 2000Date of Patent: November 20, 2001Inventor: Anne Craine

Patent number: 6105961Abstract: A soccer board game of the type familiarly known as "foosball" has horizontal rods for operating the defense and offense manually. If a player wishes to practice the only option is to place all of the defensive rods in one position, and to leave them in that position while he plays the offensive. This is very unsatisfactory. I propose the electrical control of the defensive rods, so that the defensive set-up can be varied by presenting the offense with a myriad of defenses. This is accomplished by the use of an electric motor and a cam to set the defensive position. Alternatively, a rectangular wave is generated and applied to the defensive rods to change their position as wanted.Type: GrantFiled: November 30, 1998Date of Patent: August 22, 2000Inventor: Micheal L. Price

Patent number: 6085647Abstract: A packer as provided for lawn waste disposal for compacting and channeling it into a throwaway bag. The disposer includes an upper portion with converging walls and a lower portion with parallel walls forming a chute into a bag. The entire structure is made of sheet polyethylene and it is entirely rectangular in outline. The upper portion, the converger, is only one-half the height of the lower portion, the chute, to prevent overbalancing. The chute is polyethylene, of which the disposer is made, is reinforced at discrete locations, the converging edges and the bottom edge, of plastic of the same type from which the disposer is made to keep the disposer light in weight, yet strong. A folding metal frame supports the disposer at bag height.Type: GrantFiled: September 10, 1998Date of Patent: July 11, 2000Inventor: Paul D. Burow

Patent number: 5971367Abstract: A bypass is provided between the hot air pipes carrying heated air from a furnace and a cold air pipe carrying the return air to the furnace. A certain percentage of the air thus is bypassed. A scented pellet is provided in the bypass and is heated when the air is heated, and thereby evaporates a scent into the air. (It will evaporate scent when the air is cold, also.) Passage of the scent to the cold air pipe insures that it is heated again by the combustion chamber of the furnace, and the scent thereby is fairly evaporated and spread through the heating system.Type: GrantFiled: August 13, 1997Date of Patent: October 26, 1999Inventor: Neil Skelding

Patent number: 5349947Abstract: A powder inhaler and process are provided for aerosolizing finely powdered or pulverized medication and a gas provided in a pillow or blister-type container of extremely thin elastic suitable plastic construction. The pillow is compressed between an anvil with a conical depression and a confronting conical piston. The conical depression has a small orifice at its apex, and the periphery of the pillow is restrained so that compression between the conical pillow and the conical depression produces explosive rupture of the pillow and exit of the gas and medication at a very high speed up to supersonic through said orifice. Medication particle clumps are very efficiently separated into separate particles, and the gas/medication exiting from the orifice are conveyed through a very small area linear or curved tube to a dispersal chamber or directly to a patient, movement through the tube producing a shearing action further enhancing separation of aggregated particles of powder medication.Type: GrantFiled: July 15, 1993Date of Patent: September 27, 1994Inventors: Michael T.
