  • Patent number: 10975912
    Abstract: A bearing assembly includes a bearing cage and a supplementary ring. The bearing cage includes an annular body and a plurality of bearing elements disposed about the annular body. The supplementary ring includes an annular collar and a plurality of retention elements. The annular collar is disposed concentrically about the bearing cage. The plurality of retention elements is connected to and extends axially from the first annular collar. Each retention element is aligned between adjacent bearing elements. The plurality of retention elements is disposed to retain the plurality of bearing elements in the annular body of the bearing cage.

  • Patent number: 4522314
    Abstract: A toothpick dispenser for vertically dispensing a toothpick includes a stationary base having an upright cylindrical housing, and a cylindrical body for containing toothpicks which is telescopically received within the housing for vertical sliding movement therein. An upstanding stationary support stand projects axially from the base within the housing, and the movable body includes a cone-shaped bottom that slopes inwardly and downwardly toward a central opening which slidably receives the support stand. When the body is moved upwardly to its loading position a single toothpick passes through the opening in its bottom and is received on end by the stand. When the body is moved downwardly to its dispensing position the stand closes the opening in the cone and the toothpick projects from the body in an upright vertical positon. The dispenser also includes a removable cover for the body having a guide member for directing the toothpick through an opening in the cover.

  • Patent number: 4361246
    Abstract: A container having a cylindrical body and a pair of end panels includes a single seam construction for sealingly connecting the end panels to the body. Each end panel includes an integral upright flange which is curled outwardly at its free end for receiving the terminal end of the container body so that the outer surface of the flange intimately engages the outer surface of the body. The seam is then constructed by deforming the flange and container body inwardly and then outwardly so that the terminal end of the flange abuts the outer surface of the container body.

  • Patent number: 4357794
    Abstract: The present invention relates to a rotary-reactive internal combustion engine in which the reactive powers of the exhaust gas add to the driving torque of the present engine. The classification of this engine: The kind of the fuel is a liquid fuel. One cycle consists of the three working periods. The ignition of the fuel realizes inside the four combustion chambers by the high-tension ignition. One cycle is corresponding to a 360.degree. turning angle of the shaft of the rotor. The method of the formation of the mixture is the external mixing or is the pump fuel-air mixture with a very high pressure feed. The constructional distinctness is the rotary engine. The method of the formation of the power is the reactive power. The process of the scavenging is through forced scavenging. The present engine will be able to create the power and will work with a high speed rotation. This engine system allows it to use both synthetic fuel and common gasoline.
