  • Patent number: 4217857
    Abstract: An improved pet relief station for the receiving of pet excrement, the relief station comprising a screen pan having a screen portion, and a pair of receiving pans that are alternatively stackable one in the other. The screen pan is placed in one of the receiving pans, and this pan is in turn stacked in the other receiving pan. Pet litter is disposed in the screen pan to cover the screen portion thereof. Once pet solids have been deposited on the pet litter, the solids are removed by lifting the screen pan, sifting the pet litter which separates the pet solids onto the screen portion, and disposing of the solids. Immediate reassembly of the relief station is afforded by separating the receiving pans, positioning the screen pan in the empty receiving pan, and then pouring the litter over the screen portion of the screen pan. The receiving pans are then restacked.

  • Patent number: 4192484
    Abstract: A disc valve includes a seat ring having a butt portion anchored to the body of the valve and a seal portion which extends axially from the butt portion. The disc of the valve is axially aligned with the seal portion of the seat ring so that the valve is sealed via engagement of the seal portion with the periphery of the disc. An annular cavity is formed about the seal portion of the seat ring and opposite ends of the cavity are vented to the valve chamber on opposite sides of the disc. An elastomeric seal disposed in the cavity is responsive to pressures of opposite ends of the cavity to close the vent to the low pressure side of the disc such that the higher of the fluid pressures on opposite sides of the disc is exerted on the outer periphery of the seal portion of the seat ring to foce the seal portion against the disc when the valve is closed.
