Abstract: A piston pump is provided in which the piston-chamber forming member has a chamber within which a piston of a piston forming element is coaxially slidable. A locating member is provided on the piston forming element for engagement of the piston-chamber forming member externally of the chamber to assist the piston-chamber forming member and the piston forming element while sliding axially maintaining the piston centered and coaxial relative to the chamber.

Abstract: A universal wall plate which can be secured to a wall and to which a variety of dispensers can readily be secured and removed with minimal effort, without the need to remove the wall panel and without causing damage to the wall.

Abstract: A method and apparatus for extruding the first fluid capable of foaming through a porous member to produce a first foamed extrudate while simultaneously dispensing a second flowable material preferably containing particulate matter adjacent the first extrudate.

Abstract: The present invention is directed to a storage element and bicycle frame that work in conjunction with each other. The present invention to makes both the frame and storage element as aerodynamic as possible when the storage element is attached to the frame. The storage element is designed to function as an integral aerodynamic element of the frame.

Abstract: These disadvantages of previously known devices, the present invention provides a vacuum released valve which closes an opening into a reservoir to passage therethrough until a sufficient vacuum is created with the reservoir as on initial dispensing of fluid from the reservoir. Furthermore a cap is preferably adapted to assume an inherent shape. The inherent shape is a shape such that when in the closed position; the cap will have an inherent bias to urge the female annular seat downwardly onto the male seat to form a seal and when deflected under vacuum conditions, to assume the open position; the inherent bias of the cap, on release of the vacuum, will cause the cap to reassume the position.

Abstract: An assembly for mounting of a lever member to a housing in which a stop member which normally limits rotation of the lever member about a fulcrum is movable to a position which permits the lever member to be disengaged from the housing and removed.

Abstract: A simplified arrangement for the translation of movement as, for example, arcuate movement as from a lever into movement which is different as for example, in a linear direction with a slide element preferably comprising a piston in a piston pump. In accordance with a preferred aspect, the present invention provides a bridging element which is disposed intermediate a pivoting lever and a linearly sliding slide element with the bridging member being retained in engagement with camming surfaces having an arcuate portion at a constant distance from the pivot axis of the lever and tangentially merging into a linear portion which is parallel to a longitudinal axis along which the slide element is slidable. The bridging member is slidable relative to the camming surface with the bridging member deforming to assume the shape of the camming surface where the bridge member engages the camming surface.

Abstract: A front fork for a bicycle having an upwardly extending mast of an aerodynamic teardrop shape to which a handlebar may readily be attached.

Abstract: An external locking mechanism for a filing cabinet incorporating two hinged blocking plates at each side of the cabinet and a locking bar which is movable without removal from attachment to the cabinet to positions such that the blocking plates can be selectively prevented from being moved to unblocked positions or permitted to be moved to unblocked positions.

Abstract: A spring member extending from a first end to a second end about a longitudinal axis, the spring having an inherent bias to assume an extended position with a first end spaced from the second end along the axis, the spring assuming compressed positions when compressed by forces applied parallel to the axis, in the compressed positions the spring resiliently urges its first and second ends axially away from each other toward the extended position, the spring member having a wall in the shape of a solid of revolution rotated about the axis and defining a central cavity therein open at the first end of the spring and substantially closed at the second end of the spring, the wall when in the unbiased extended position having a greatest diameter at the first end and a least diameter at the second end, a plurality of openings through the wall, the openings disposed symmetrically both circumferentially and axially relative to each other.

Abstract: A lever with a shifting pivot or fulcrum point such that in pivoting of the lever between a first position and a second position for at least one angular segment of such pivoting about a first fulcrum point and for a second angular sector of such pivoting, pivots about a second fulcrum point.

Abstract: A coupling mechanism for coupling a nozzle shield to a dispenser housing using interacting hook members and axle members. One of the hook members and axle members is carried by the housing. The member which is carried by the housing is preferably movable between a forward and a rear position as by being slidable relative to the housing and spring biased as to a rear position. In moving the cover from a closed position to a forward position, the hook member and axle member are in engagement with the member which is movable relative to the housing, preferably moved against the spring bias. For removal of the cover, with the cover approximate the closed position, the member which is carried by the housing is moved relative the housing against the spring bias to a forward position in which the hook member may be disengaged from the axle member.

Abstract: A spring mechanism comprising an elongate cantilevered spring member extending along a longitudinal coupled at a first end to a first member and with a distal, second end of the spring member engaging a second member such that the spring member biases the first and second members relative to each other. The spring member has an unbiased condition and being resiliently deflectable generally normal to its longitudinal to assume deflected conditions from which the spring member inherently attempts to return to its unbiased condition. The longitudinal of the spring member preferably remains disposed in a flat plane in deflecting of the spring member between the unbiased condition and the deflected conditions. The spring member preferably has, in cross-section normal to its longitudinal, a shape including two legs disposed to lie in planes parallel the flat plane and joined by a bight normal to the flat plane.

Abstract: A stacked cabinet structure for vertical stacking of a lower cabinet with a top wall and an upper cabinet with a bottom wall in which a spacer member is provided intermediate the top wall of the lower cabinet and the bottom wall of the upper cabinet with the spacer member supported by the top wall of the lower cabinet and supporting the bottom wall of the upper cabinet forming a horizontally extending raceway vertically between the top wall of the lower cabinet and the bottom wall of the upper cabinet for passage of utility wiring. The raceway preferably is open at least at a front access opening preferably with uninterrupted access provided to the raceway inwardly from the front access opening through the entire width of each cabinet from a first side to a second side.
