  • Resuscitation device
    Patent number: 5787880
    Abstract: A resuscitation device including an air delivery device which has two rigid walls moveable toward and away from each other, is substantially rectangular, but may have rounded corners; a scissor type mechanism is employed to maintain parallelism of the walls; optional adjustment means is provided to adjust the delivered volume from at least 1200 ml, for an adult patient to a lesser amount for children and a still lesser amount for infants; the adjustment device may be coordinated with mens for simultaneously adjusting the maximum delivered pressure to levels appropriate to the adult, child, or infant patient; economy in storage and quantity of devices required is achieved.

  • Composite grinding wheel
    Patent number: 4910924
    Abstract: A two zoned grinding wheel is disclosed having a lower section or zone composed of bonded abrasive grain and an upper zone or section made up of bonded particles of a material that is softer than the abrasive grain and therefore less abrasive. The wheel is especially suitable for being held in clamps or a chuck when being used, with the clamps or chuck contacting the wheel on the upper less abrasive section thus greatly reducing wear on said clamp or chuck.

  • Frit bonded abrasive wheel
    Patent number: 4898597
    Abstract: A grinding wheel is disclosed which is made up of sintered aluminous abrasive and a vitrified bond, the vitrified bond being a frit. A large portion of the sintered aluminous abrasive may be replaced by a non-sintered abrasive and the bond may include fillers and/or grinding aids.
