  • Publication number: 20070142188
    Abstract: A weight plate have integrally formed handles is provided. The weight plate has a weight plate body having an outer periphery, a first side, and a second side that is substantially flat. The weight plate also has a central bore extending through the body, a raised flange member forming a portion of the outer periphery on the first side, and at least one handle opening extending through the body and through ht least a portion of the outer periphery. The handle formed by each handle opening, the corresponding recess, and the raised flange member is sufficient for a human hand to grip. In one embodiment, the weight plate further includes an interlock for interlocking the weight plate with another weight plate when positioned together. In another embodiment, the weight plate further includes a pock defined in the weight plate. The pock allows the weight of the weight plate to be adjusted to a desired weight by allowing additional material to be added to the pock.

  • Publication number: 20060229172
    Abstract: An improved weight plate includes a planar body having a central opening for receiving a barbell or dumbbell bar therethrough. The weight plate includes oppositely facing flange members extending partially about the perimeter of the weight plate. The opposed ends of the flange members are spaced from each other and define a gap therebetween. The flange members extend perpendicularly from both sides of the weight plate planar body about the perimeter thereof. The weight plate includes at least one opening formed adjacent the perimeter of the weight plate. The opening is adapted to receive one or more fingers of an average human hand for securely grasping and lifting the weight plate. Adjacent weight plates mounted on a barbell bar are adapted for interlocking engagement.

  • Patent number: 4096406
    Abstract: For a grid-controlled electron source to operate at extremely high frequencies, as in planar triodes, the control grid must be situated very close to the emissive cathode. Mechanical and thermal distortions have put minimum limits on grid spacings and hence on the maximum operating frequency of grid-controlled tubes. To overcome these limits the grid structure is formed as a network of web members which are part of a laminated sheet having metal layers bonded to opposite surfaces of an insulating layer. One metal layer is affixed to the emissive surface of a metallic matrix cathode and the other metal layer forms the control grid.
