摘要:
A dual spout-type faucet with controllable conventional-flow and mister-flow rates is provided. In a first mode, one or more mister elements, or apertures having mister-like openings, are co-located proximate to a spout outlet, wherein water flow rates to the mister elements (or openings) and spout outlet are both controllable by one or more valve controllers accessible to a user. In a second mode, one or more mister elements, or apertures having mister-like openings, are co-axially located in a spout outlet wherein water flow rates to the mister elements (or openings) and spout outlet are both controllable by one or more valve controllers accessible to a user. In another embodiment the apparatus may be handheld and positionable and equipped to dispense soap or a cleaning solution optionally including attachable scrubbers.
摘要:
An aircraft fuel tank ullage safety system (10) that is designed to maintain the fuel tank ullage (94) of an aircraft fuel tank (90) filled with nitrogen. The nitrogen prevents the fuel tank ullage (94) from becoming filled with flammable fuel fumes which can cause an explosion. The system (10) consists of at least one flexible, resilient, air-enclosing container (12) having a container ullage (50) that is dimensioned to substantially occupy the space of the fuel tank ullage (94), a differential pressure sensor (30) that determines the internal pressure of the aircraft's fuel tank (90) and a microcontroller (64) that controls and maintains the volume of the air-enclosing container (12) as determined by the differential pressure sensor (30).
摘要:
An aerosol spray can (12) that can only be operated when connected to an a-c utility power source provided by a power cord (50A) connected to an external activator (40). The can is modified by adding internally, a movable armature (19) that operates a valve assembly (16) connected to a spray head (20). When the armature is not energized by the attached activator (40), the valve assembly (16) remains in a closed position, preventing the flow of paint. Conversely, when the movable armature (19) is energized by the activator (40), the valve assembly (16) opens allowing paint to be sprayed when the spray head (20) is depressed.
摘要:
A utility-power operated tamper-proof pressurized spray can (10) which can only be operated when connected to a utility a-c Power source. Thus, its use to spray graffiti is prevented or at least minimized. The spray can (10) is presented in two design configurations. In the first design, a solenoid/valve assembly is mounted on the top cover of a spray can and on the second design the solenoid/valve assembly is located on the can's lower cover. The first design utilizes a housing (12) that encloses the solenoid/valve assembly which consists of an upper fixed armature (20), a moving armature (36) and a lower fixed armature (58). Between the upper fixed armature (20) and the moving armature (36) is inserted a compliant leaf (48) that functions as a valve. Around the housing (12) is removably attached an electric coil (86) that when connected to a utility a-c power source produces a magnetic field that is applied to the solenoid/valve assembly. The magnetic field causes the moving armature (36) to be displaced which separates the complaint leaf (48) which then allows paint to flow upwards and be sprayed. The arrangement of the upper fixed armature (20) and the moving armature (36) precludes the use of a permanent magnet to cause the moving armature (36) to move downward into the paint spraying positions
摘要:
An aerosol spray can (12) that can only be operated when connected to an a-c utility power source provided by a power cord (22) that includes a power-line activator (30). Thus, the use of an aerosol spray can (12) to spray graffiti is prevented or at least minimized. The can (12) is modified by attaching to its upper section (14) a valve attachment port (16) to which is attached a lower fluid port (86) located on a slide and twist valve (80). The valve (80) also includes an upper fluid port (84) having a check valve (88) that opens when a standard spray head (26) is depressed and a permanent magnet piston (90) having a fluid passage bore (96). When no power is applied, a compression spring (94) positions the piston (90) with the bore (96) misaligned in both a radial and longitudinal position that prevents the passage of the fluid. Conversely, when power is applied, an electromagnet (36) in the power-line activator (30) aligns the fluid passage bore (96) with the upper and lower fluid ports (84,86) to allow fluid to pass when the spray head (26) is depressed.
摘要:
A computer monitor viewing device is provided which locates a monitor image at a comfortable viewing location and which is desirably suitable for use by most computer users and, in particular, by bifocal users. The device includes a first mirror positioned to reflect an image from a computer monitor screen and a second mirror which is positioned to reflect the image reflected by the first mirror toward the eyes of a viewer. Supports are also provided for positioning the first and second mirrors. Desirably, where the device is used in connection with a keyboard, the second mirror is positioned closer to the keyboard than the computer monitor screen, thereby allowing users, including bifocal wearers, to comfortably view the screen and the keyboard simultaneously. The device may also incorporate means to shield the user from radiation from the computer monitor.
摘要:
An articulating platform (20) that is used to vary the longitudinal and lateral angular displacement of an exercise bicycle (22) mounted thereon. The platform includes a bicycle mounting base (24) configured to accept the footprint of a conventionally dimensioned exercise bicycle. The base (24) pivots in both a longitudinal axis and a lateral axis, thereby simulating uphill and downhill bicycle riding and turning when leaning sideways in a turning direction. The base (24) is preferably articulated by a D.C. motor drive system or optionally by a gear motor, pneumatic, hydraulic and worm drive systems each having controls for initiating directional articulation. A platform enclosure (40) supports the base and the drive system to provide a safety barrier for protecting moving components of the platform.
摘要:
An anti-graffiti aerosol spray can (10) that features an internal spray head valve control assembly (60). The assembly (60) includes a spray head valve actuator (62) that can consist of a solenoid (63), a valve (65), a bi-metallic detent structure (122) or any other electrically-operated device having an open and shut mechanism. The internal spray head valve control assembly (60) operates by the application of an electrical power source (98) that is applied from two electrically isolated sections of the spray can (12). The assembly (60) can be designed to be operated by an electrical device that is attached directly to the aerosol spray can (12), or the assembly (60) can be operated by an RF receiver (150) that is energized by a remotely-located RF transmitter (152) that is energized by a d-c power supply (154) connected to a 120-vac, 60 Hz utility power source (156).
摘要:
A theatrical follow spot utilizes elliptic reflective optics to achieve compact size and non-astigmatic projection. A source lamp is situated in front of the mirror, sufficiently offset to one side thereof so as to be out of the path of reflected light. The mirror has the shape of an ellipsoid of revolution, the mirror section being entirely on one side of a meridian plane of the ellipsoid. The axis of light from the source lamp is coincident with a line through the near focus of the ellipsoid and the center of the mirror. This insures that an image in the near focal plane, such as the circular opening of an iris, will be projected at the distant focal plane of the ellipsoid, without distortion of shape.
摘要:
A self-rinsing urinal and very low water-usage mist-dispensing means mountable in close proximity to a normally-interior portion of at least one positionable panel configured slidably or pivotally positionable from an opening of customary cabinetry of a room or a wall. The urinal is positionable from the customary cabinetry or wall opening, between a zero-footprint concealed state and a revealed-for-use state, such that an interior receptacle surface of the urinal is aligned with said very low water-usage mist-dispensing means during at least a revealed-for-use state, to receive from the mist-dispensing means a distributed misted spray aligned with the receptacle, to repel waste-liquid from and facilitate a self-rinsing of the receptacle while employing as little as single-digit ounce(s) of water, per use-cycle. Certain of the embodiments include the option to provide actuating means for positioning and/or aligning one or more urinal-related components in response to receiving a control signal.
