Abstract: The present invention is directed to a method of enhancing the appearance of a soiled porous surface. The inventive method includes applying a concentrated, alkaline, cleaning composition to the soiled porous surface. This concentrated, alkaline, cleaning composition is then allowed to remain on the surface for a period of time before it is rinsed with water. After drying, a maintainer composition is then applied to the surface. The maintainer composition includes a pore-filling component. The cleaning composition includes an alkaline source and, optionally, a solvent.

Abstract: A continuous bulk polymerization and esterification process includes continuously charging into a reaction zone at least one ethylenically unsaturated acid-functional monomer and at least one linear or branched chain alkanol having greater than 11 carbon atoms. The process includes maintaining a flow rate through the reaction zone sufficient to provide an average residence time of less than 60 minutes and maintaining a temperature in the reaction zone sufficient to produce a polymeric product incorporating at least some of the alkanol as an ester of the polymerized ethylenically unsaturated acid-functional monomer. The polymeric product is used in various processes to produce water-based compositions including emulsions and dispersions such as oil emulsions, wax dispersions, pigment dispersions, surfactants and coatings which contain the polymeric product.

Abstract: A self metering dispensing device for dispensing a predetermined quantity of material from an aerosol container. First and second actuating members are pivotally connected to a housing for the container and a nozzle actuating member is connected to the first actuating member. A pneumatic member in the form of a cylinder with a piston or a telescoping valve is operatively associated with the first and second actuating members. A compressive force placed on the second actuating member causes the nozzle activating member to contact the container valve to dispense product from the container. A controlled metering of product is produced by an air regulator connected to the pneumatic member.

Abstract: The present invention provides a highly universal out-of-liquid sensor that allows an out-of-liquid condition to be accurately detected for a long time, and provides a liquid supply device using the same.

Abstract: An eductor (1) for mixing liquids, e.g. a concentrated solution into water, has a flow passage (16) for a first liquid into which a dispensing passage (18) for a second liquid opens so that in use the second liquid is drawn into the flow of the first liquid. The dispensing passage (18) including a flow restrictor portion provided by a groove (22) extending on the periphery of a restrictor plug (19) removably received in a socket (21) of the eductor body. The groove (22) and the wall of the socket (21) define the flow rate in the dispensing passage. The plug (19) has a plurality of the grooves (22) and is selectively insertable into the socket in a plurality of positions, the grooves providing respectively different flow rates of the second liquid.

A valve assembly is fixed to the container, and is in fluid communication with the volume. The valve assembly is connectable to a fluid conduit which supplies a second fluid to the valve assembly. A handle strap is fixed relative to the container and the valve assembly, and has a conduit support engaging the container for supporting a conduit.

Abstract: A kitchenware washing apparatus has a wash tank and a heated tank connected in a manner that they have a common wall for maximum water heating efficiency. In a preferred manner, the common wall has a tiered configuration. A particle accumulator is positioned inside a cabinet of the apparatus and in a flow path of the overflow drain water from the wash tank.

Abstract: A dispenser for mixing and dispensing a liquid chemical concentrate with a dilutent from a container. The dispenser includes two slideable eductors one of which is also rotatable. Both a high and low flow rate can be obtained with simultaneous adjustment of concentration of the chemical concentrate. The dispenser has a high degree of accuracy of the amount of dilution of the chemical concentrate as well as positive positioning of the high and low flow rate.

Abstract: A method for detecting protein present on the surface of a sample is disclosed, wherein substances present on a portion of said surface are transferred to a sampling means and wherein, subsequently, these substances are contacted with a reagent capable of forming or changing color upon reaction with protein. Finally, the color changed or formed by this reaction is visually determined. In this method, the substances transferred onto the sampling means are also contacted with a specific type of nonionic or zwitterionic surfactant.

Abstract: A substantially non-gelled polymeric composition is disclosed and comprises the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with the reactive functional groups of the A polymer.

Coating compositions may be deposited and cured by heating to form crosslinked coating compositions. Such crosslinked coating compositions exhibit excellent solvent resistance.

Abstract: An apparatus periodically dispenses an air freshening substance from a pressurized container into a room. A device is provided to sense when the room is occupied, such as by detecting the light level in the room. The air freshening substance is dispensed more frequently when the room is being used than at other times. However, the dispensing continues even when the room is unoccupied to treat odors arising from objects permanently located in the room.
