Abstract: A construction of an upright panel unit adapted for use in a wall with the panel units abutting end to end in which a pair of spaced facing sheet members on either side of the panel unit have vertical edge portions joined at each end of the panel unit by being sandwiched between an inner bracket member and an outer bracket member, with the outer bracket member having male and female arms engageable and disengageable with an outer bracket member of the end of an adjacent panel unit merely by respective movement of the panel units longitudinally relative to each other.

Abstract: The present invention provides a combination of a door and door frame defining a door opening. The door frame comprises a horizontal header beam. The door opening has a horizontal top side and a horizontal bottom side, with the horizontal header beam defining the horizontal top side. The door comprises a top panel, a middle panel, a bottom panel, a first horizontal hinge member, a second horizontal hinge member and a third horizontal hinge member, each panel having a horizontal upper edge and a horizontal lower edge. The door is in the closed position when the top panel, the middle panel and the bottom panel are vertically aligned with one another and hanging downwardly from the horizontal header beam in a vertical plane of the door opening, with the horizontal upper edge of each panel above the horizontal lower edge of each respective panel, and the horizontal lower edge of the bottom panel is located in the lowermost position proximate to the horizontal bottom side of the door opening.

Abstract: A piston pump in which the piston carries a valve and a control mechanism to change a characteristic of the valve, preferably, its tendency to open. The valve may preferably comprise a disc which extends radially outwardly from the piston to resiliently engage the wall of piston chamber. The control mechanism preferably provides an access port communicating axially through the piston and axially out an opening of the piston chamber. In a preferred embodiment, the control mechanism comprises a bladder with a flexible side wall which can be moved from an inherent uncollapsed position to a different position and which bladder is inherently biased to return to its uncollapsed position.

Abstract: A urinal discharge pipe assembly comprising a discharge pipe having a passageway therethrough from an inlet in communication with a urinal discharge outlet and an outlet in communication with a urine disposal system, a foam dispensing device having a foam outlet open into the passageway for discharge of an allotment of foam into the passageway between the inlet and the outlet adequate to form a temporary foam plug across the passageway blocking the passageway.

Abstract: The present invention relates to a process for forming a variable gauge metal sheet into a desired shape, said process comprising: providing a variable gauge metal sheet having a first surface and a second surface, the metal sheet having a thickness measured at any point on the metal sheet as the distance between the first surface and the second surface, the thickness of the metal sheet being different over a first portion of the sheet than over a second portion of the sheet, and forming said metal sheet into a first desired shape by bending the metal sheet about a first fold line, said first fold line extending through both the first portion and the second portion, to bring segments of the first surface of the metal sheet on either side of the first fold line into increased opposition with each other.

Abstract: A method of controlling operation of a mechanism, preferably a dispenser, having a removable component comprises measuring electromagnetic radiation passing through a wave guide carrying at least in part on the removable component and permitting operation of the mechanism only when the measured electromagnetic radiation corresponds with one or more pre-selected parameters. Preferably, the method involves directing emitted electromagnetic radiation with pre-selected input parameters selected from a plurality of input parameters.

Abstract: A partition with a frame having two vertical end post members spanned by beam members with each end post member having an internally directed longitudinal slotway open towards the other end post member and within which the ends of the beam members are received and, preferably, with the end post members having a front to back width greater than the front to back width of the beam members such that vertical raceways are defined between the post members outward of the beam members and inward of removable cladding panels coupled to each front and back of the frame outward of the post members. Preferably, channelways through each post member, preferably at the upper and/or lower ends of each post member, provide for access to the vertical raceways via horizontal raceways extending between the posts above and below each beam.

Abstract: A piston pump having a piston forming element carrying at an inner end a removable member which becomes secured in a piston chamber forming member and detached from the piston forming element within the piston chamber forming member.

Abstract: An electro chemical conversion cell that can break down certain gasses to provide ozone and monovalent oxygen from a supplied volume of a suitable 02-containing gas. The conversion cell is provided with at least one metal mesh electrode within a generator reaction chamber, and a power supply which is adapted to supply a high alternating electric current voltage to at least partially break-down O2 in the input gas to yield ozone. A fluid flow passage extends through the reaction chamber as a generally elongated passage through the reaction cavity. The fluid flow passage extends from an upstream end, where the O2-containing gas is initially supplied into the housing, to a downstream end where treated gas either flows outwardly therefrom under pressure or is evacuated from the housing. In a simplified construction, the fluid flow passage is delineated by a series of electrically insulating plates and/or spacers which are used to partition the reaction cavity.

Abstract: A gutter cover comprising a sheet having a front portion, a rear portion, and a central portion extending between said front portion and said rear portion; said central portion having a plurality of openings for passage of water therethrough, said front portion comprising an upper wall segment, a bend segment, and a lower wall segment, wherein said upper wall segment extends forwardly from said central portion to said bend segment, said bend segment joins said upper wall segment and said lower wall segment, and said lower wall segment extends rearwardly from said bend segment and underneath said upper wall segment, wherein a space is formed between said upper wall segment and said lower wall segment, wherein a first fastener extends through openings in said upper wall segment and said lower wall segment, and wherein a distance between an upper surface of said upper wall segment and an upper surface of said lower wall segment is greater than or equal to an axial height of a head portion of said first fastener.

Abstract: A liquid dispenser, particularly advantageous for low viscosity solutions, such as, alcohol solutions, for dispensing from an upper open end of a reservoir out an outlet at a height above the level of liquid in the reservoir onto a user's hand disposed below the reservoir, advantageously by actuation of an actuator below a lower end of the reservoir.
