Abstract: A rubberized chemical emulsion having rubber added to an anionic material after the anionic material has passed through a colloid mill.

Abstract: A vault door opener for opening a vault door wherein the vault door is disposed near a grating. The vault door opener comprises a stand with a winch connected to one end of the stand. Means are connected to the opposite end of the stand for removably connecting the stand to the grating whereby the stand is supported in an upright position on the grating. In the supported position of the stand, a cable on the winch is connected to the vault door and the winch is rotatable to reel the cable in thereby lifting the vault door to the opened position.

Abstract: A method for reducing the concentration of target co-ions in a liquid feed mixture comprising target co-ions and counter-ions by adding a colloid such as a polyelectrolyte or surfactant comprising a colloidal ion and colloidal counter-ions to the feed mixture wherein the colloidal ion has the same type of charge as the target co-ion. The feed mixture containing the colloid is filtered through an ultrafiltration membrane having pores small enough to block the passage of the colloidal ion.

Abstract: A male die, a female die, air pressure and vacuum are used to form a sheet of material into a flat-paneled flower pot or flower pot cover. A platform supports the female die which has an opening with flat surfaces for forming panels in the base and skirt of the flower pot or flower pot cover. The male die has forming surfaces which mate with the forming surfaces of the female die. The sheet of material is centered over the opening of the female die. A bracket having a plurality of legs which align with the panel-forming surfaces of the female die is placed on the sheet of material. Air pressure and vacuum lines communicating with the opening of the female die are used to control the sheet of material as the male die enters the opening of the female die. The top surface of the platform and the bracket legs provide additional control of the sheet of material. The sheet of material is pressed between forming surfaces of the male and female die to form the flat-paneled flower pot or flower pot cover.

Abstract: A wastewater treatment system for treating wastewater containing undesirable pollutants which comprises a housing having a bottom and defining an internal chamber. The internal chamber is provided with a first and second baffle member which cooperate to define a mixing zone and a separation zone. Wastewater (containing a sufficient amount of air so that the air present in the wastewater exceeds the solubility of air in the wastewater) is introduced into the mixing zone of the internal chamber, and an aerated water is sprayed into the wastewater to produce a quantity of air bubbles sufficient to promote the flotation of pollutants having a density approximately equal to that of the wastewater to form a froth. Pollutants having a density substantially greater than the density of water settled to the bottom portion of the housing. An effluent reservoir assembly (which forms a reservoir zone) is spatially disposed from the second baffle member so that a quiescent zone is formed therebetween.

Abstract: An adapter for connecting a plastic pipe to a metal pipe. The adapter consists of a connector having a first end and a second end with an opening extending through the second end of the connector and extending a distance through the connector toward the first end of the connector forming an inner peripheral surface. The second inner peripheral surface of the connector is threaded forming a second inside diameter of the connector which is smaller than an outside diameter of the plastic pipe. The end of the plastic pipe is threaded into the opening through the first end of the connector with the threads digging into an outer peripheral surface of the plastic pipe and compressing a portion of the plastic pipe near the first end thereof for connecting the plastic pipe to the connector. The second end of the connector is adapted to be connected to one end of the metal pipe.

Abstract: A flight assembly for use in a conveyor wherein the flight assembly includes at least two flight links. The two flight links are removably connected in an end to end relationship for maintaining an alignment between the forward faces and the rearward faces of the two flight links. In one embodiment, a plurality of flight assemblies are incorporated in a take-away conveyor. In one other embodiment, each flight link has an angled portion and a curved portion formed on each of the first and second ends thereof for permitting articles to slide over the forward faces and the rearward faces of the flight links without engaging one of the ends of the flight projections in a manner disturbing such sliding movement.

Abstract: A water cooled engine includes a thermostat interposed in a water flow passage way. The thermostat operates a valve which opens and closes to regulate the temperature of water. A bypass structure assembly is associated with the thermostat for permitting the flow of water through the thermostat to be controlled by the valve in the thermostat in an operating position of the bypass structure assembly and for bypassing the thermostat in a bypass position wherein water flows through the flow passageway bypassing the thermostat. A bypass position assembly is associated with the bypass structure assembly for positioning the bypass structure assembly in the operating position and in the bypass position.
