  • Publication number: 20240110084
    Abstract: The present disclosure provides laminates, which include adhesive materials and methods that allow for the removal of contaminants, e.g. particulate contaminants, from a substrate surface. In one embodiment, the laminates include (i) a substrate with contaminant disposed on its surface, (ii) a liquid, adhesive precursor and (iii) a film layer. The liquid, adhesive precursor is disposed between the substrate and the film layer. In another embodiment, the laminates include (i) a substrate with contaminant disposed on its surface, (ii) a cured adhesive layer and (iii) a film layer. The cured adhesive layer is disposed between the substrate and the film layer. The laminates may be used to remove contaminant from the substrate surface by removal of the film layer and the cured adhesive layer, which entraps the contaminant therein.

  • Publication number: 20080052952
    Abstract: An invention is provided for a hand drying apparatus for drying and sanitizing hands is disclosed. The hand drying apparatus includes a housing having an air intake opening and a heating element situated within the housing capable of heating air drawn into the hand drying apparatus through the air intake opening. Also located within the housing is an air conduit that is in communication with the air intake opening. Further included is a blower that is capable of drawing an air stream into the air conduit through the air intake opening. An ozone gas generator is in communication with the air conduit that is capable of injecting ozone into the air stream to create an ozonated air stream.

  • Patent number: 7097160
    Abstract: The present invention includes an improved apparatus (10) for treating a liquid with a gas having a generally cylindrical outer housing (24) and a coaxial inner housing (40) defining both an outer and an inner chamber (26, 46) and a plurality of inlets (70, 80) for introducing a fluid and a gas therein to generate a helical current throughout both chambers (26, 46). The present invention further includes a re-circulated fluid outlet (100) and a primary fluid outlet (104) for removing mixed fluid and gas that is disposed radially outwardly in a bottom portion of the inner chamber (46).

  • Patent number: 6361688
    Abstract: An inner housing (38) is positioned within an outer housing (36). An gas/liquid mixture is caused to flow along a helical path upwardly through an outer chamber (70) that is formed by and between sidewalls (56, 64) of the outer and inner housings (36, 38). The gas/liquid mixture flows through a passageway (74) between a top end wall (62) and an upper end edge (66), from outer chamber (70) into an inner chamber (72). Residual gas is removed from the gas/liquid mixture by a gas-vent device that projects from top end wall (62) downwardly into the inner chamber (72). Liquid in the inner chamber (72) flows downwardly through an outlet opening (54) into an outlet conduit (44). The outlet conduit (44) has an effluent branch that removes liquid from the apparatus. It also includes a second branch conduit that delivers some of the liquid to the inlet of a re-circulating pump (34). The re-circulating pump (34) pumps the re-circulated liquid back into the lower end of the outer chamber (70).

  • Patent number: 6054046
    Abstract: A gas treatment system for liquids can increase gas exposure and contact time. A liquid stream is directed into a vortex chamber (130). The vortex chamber (130) creates a downward spiral flow of the liquid stream forcing it into an upper end inlet (145) of a contact tank (114) and downward in the contact tank (114). When the liquid stream reaches a lower region (170) of the contact tank (114), a portion is drawn into a draw tube (120) while the other portion is drawn into a re-circulation system (160). In the re-circulation system (160), a gas injector system (166) entrains bubbles of a treatment gas into the liquid stream creating a re-circulated stream that is displaced into an upper region (168) in the contact tank (114). The portion drawn into the draw tube (120) then moves upwardly to a degassing chamber (146) wherein the treatment gas is separated from the liquid and delivered through an outlet (124) for use.

  • Patent number: 5865995
    Abstract: A gas treatment system for liquids can increase gas exposure and contact time. A liquid stream into which treatment gas is added is directed into a vortex chamber (130). The vortex chamber (130) creates a downward spiral flow of the liquid stream forcing it into an upper end inlet (145) of a contact tank (114). The liquid stream with entrained gas bubbles is forced to move downwardly through the tank to a lower end outlet (122). The flow then moves upwardly to a degassing chamber (146) wherein the treatment gas is separated from the liquid and delivered through an outlet (124) for use. Because the entrained bubbles are forced downwardly through the contact tank (114), the gas bubbles remain quite small and contact time is prolonged. Release of the treatment gas is further facilitated by positioning the degassing chamber (146) at an elevated position which promotes gas bubble expansion, combination and release.

  • Patent number: 5351024
    Abstract: An electrical power switching device employing a rotary disc driven by an actuation means whose position is selected by a control means where disc contacts engage and disengage stationary contacts where the stationary contacts are deflected away from the disc contacts by separation ramps thereby opening the current path and an arc plate is used on the disc to control arc energy. A pair of interrupter contacts are placed in series with the rotary disc contacts where abnormally high currents cause the interrupter contacts to separate and open the current path where slot motors and/or arc plates are used to dissipate the damaging electrical arcs as the contacts make and break.

  • Patent number: 5319167
    Abstract: An electrical contractor device (80) for controlling the flow of electrical power from a source of electrical power to an electrical device according to a command signal from a controller utilizing a rotary disc assembly (90) rotated by an actuator (169) where the rotary disc assembly (90) is comprised of a rotary disc (100) supporting a disc conductor (102) having a pair of contact pads (106, 108) joined by a pair of conductor legs (109, 113) and a center section (111) where the conductor legs (109, 113) are parallel and offset one from the other straddling an axis of rotation (103) where high flow of electrical current through the disc conductor (102) generates an electro-magnetic torque in the rotary disc assembly (90).

  • Patent number: 5005364
    Abstract: An apparatus for and method of making and delivering slush ice includes providing a main housing (28) having a floor (30) and substantially cylindrical sidewalls (32). The housing (28) includes a water inlet (58) and an ice inlet (26). A pump (34) having a delivery outlet (50) is positioned to have an inlet (44) substantially centered axially within the housing (28) and spaced a predetermined distance from the floor (30). A delivery conduit (52) extends from the delivery outlet (50) of the pump (34) to a second end (72, 88) remote therefrom. A rotating agitator member (54, 54') having an axis of rotation substantially centered co-axially within the housing (28) is positioned such that the agitator (54, 54') swirls ice and water in the housing (28) substantially around the pump inlet (44). The pump (34) draws ice and water through the inlet (44) and delivers a mixture of ice and water in the form of slush ice (16) through the delivery outlet (50).
