  • Patent number: 5494718
    Abstract: A shaped rigid thermoplastic cradle and leveler for vessels such as sanitaryware is disclosed. The cradle and leveler are separately formed or integrally shaped from a single thermoformed sheet of rigid thermoplastic material. The rigid thermoplastic material has a flexural modulus of at least about 300,000 psi to provide sufficient rigidity in the sidewall of the cradle. The leveler includes an integral floor leveling means for providing a designed pitch so as to conform to the desired pitch of the floor region of the vessel toward the drain hole. The floor region comprises a plurality of tapering, alternating upper and lower contacting regions. Between each adjacent upper contacting region is defined unsupported span regions having the shortest distance between adjacent upper contact regions of not more than 12 inches (30.5 cm). Preferably the shortest distance between adjacent upper contact regions defining the unsupported span is from 2.5 inches to about 6 inches.

  • Patent number: 5364065
    Abstract: A push control faucet handle is provided for a sink having a spout which consists of a housing mounted to the sink. A water control valve is connected to bottom of the housing. The water control valve has a first pipe line connected to a water supply and a second pipe line connected to the spout in the sink. A knob rides within the housing and is adjustably coupled to the water control valve. A device is for biasing the knob to a raised position above a top surface of the sink. The knob can be manually rotated to open and close the water control valve to control the flow of water from the water supply to the spout in the sink. A mechanism is for retaining the knob in a lowered position flush with the top surface of the sink, when the knob is pressed down into the housing and for releasing the knob so it will return to the raised position when the knob is pressed again. When the knob is in the lowered position a young child will have difficulty in reaching and operating the knob.

  • Patent number: 5325548
    Abstract: A sink for washing tie-stall dairy farm milk pipeline systems includes a narrow trough at the bottom of the sink. The trough receives the inflations of milking machines placed in the sink for washing. The sides of the trough confine and constrain the inflations so that the machine does not tip over while in the sink. The water level remaining in the sink when the pipeline system is flushed through therefore can be small, leading to water savings of up to 30%. The trough is made from stainless steel sheets, bent to shape; the sides of the sink extend outwards and outwards from the trough at an angle, whereby the sink sides guide the inflations into the trough as the farmer lowers the milking machine into the sink.

    Abstract: The invention is directed to a method and apparatus for monitoring liquids ischarged intermittently from a discharge receptacle having a siphon. The liquids originate in a facility in which personnel work with open radioactive substances. Measurements are made of the radioactive charge of discharged liquids in the region of the siphon of each discharge receptacle to prevent contamination of the discharge path into the drainage system. If a radioactive limit value of radiation is detected which is above a specific threshold, discharge of the liquid into the drainage network is prevented. The discharge receptacles are then emptied individually and upwardly.

    Abstract: An illustrative embodiment of the invention provides a peripheral flange generally perpendicular to the plane of the lavatory basin. The flange has a generally downwardly, inwardly sloping surface to enable the splash water to flow into the basin within the lavatory. As the flange sweeps around the periphery of the lavatory it develops into a massive spout support. The spout support enables the spout to direct water into the basin without causing the spout to extend across the basin surface. The support also has a protruding portion that establishes a reentrant basin surface in which the overflow drain is concealed from view when the lavatory is installed.
