  • Patent number: 11548719
    Abstract: A dispenser device for storing and distributing medical electrodes. The dispenser device includes a shell having an inner volume. The shell has an aperture extending through the shell to the inner volume. A strip of a plurality of electrodes is arranged in a pattern within the inner volume of the shell. An end of the strip extends through the aperture and out of the shell. Pulling the end of the strip moves the plurality of electrodes according to the pattern. The shell is preferably a round or rectangular shape. For a round shell, the strip of electrodes is wrapped around a hub within the inner volume. For a rectangular shell, the strip of electrodes is arranged in a Z-fold pattern within the inner volume. The dispenser device may have a vapor proof cap over the aperture that prevents the electrodes from drying out within the shell.

  • Patent number: 6110360
    Abstract: A reverse osmosis water purifier system uses municipal line water pressure to separate pure water molecules from dissolved and undissolved matter. The system makes and stores product water in a sanitary enclosed pressure vessel in the absence of back pressure. A small water cell tank and a hydraulically powered control valve enable delivery at a fast flow rate near line pressure flow rate. The control valve is a combination sensing and multiple valving device that automatically turns on product water when it is called for by a user or an ice-maker. It automatically replaces water that is drawn, then turns itself off when its tank is full. It fast flushes the dirty side of its R.O. membrane while fast flow water is being drawn, and it slow flushes the same side of the membrane while the system is making product water. These alternating slow and fast flushes whisk away residue from a built-in brine restricter. All flushes sweep debris down the drain.

  • Patent number: 5318151
    Abstract: An apparatus for regulating a compressor lubrication system includes an oil-flooded rotary gas compressor, a reservoir flow connected to the compressor, a heat exchanger for cooling a lubricant, and a controller. A thermal mixing valve regulates the temperature of the lubricant flowing to the compressor. A first temperature sensor measures a discharge temperature at a compressor outlet, and provides a signal corresponding to the discharge temperature to the controller. A second temperature sensor measures a lubricant temperature at a lubricant inlet to the compressor, and provides a signal corresponding to the lubricant temperature to the controller. A pressure sensor measures the pressure at the outlet of the compressor, and provides a corresponding pressure signal to the controller. A valve means continuously regulates the supply of lubricant to the compressor, the valve means being controlled by the controller in response to the temperature signal of the first temperature sensor and the pressure signal.

  • Patent number: 4705625
    Abstract: A reverse osmosis (R.O.) water purifier system that collects and stores pure water at low pressure and dispenses it at high pressure. Impurities left behind when the water passes through a R.O. module are disposed of by two methods: the fast flush method and the slow flush method. In the fast flush method, water entering a R.O. module may take two paths to escape therefrom. The first path constrains it to travel through a semi-permeable membrane in the module which filters out undissolved solids and which restrains the passage of dissolved liquids. The second path allows it to travel through the R.O. module, without passing through the membrane, thereby carrying out those impurities left behind by the water passing through the membrane. The purified water is directed to one side of a compartmented storage tank and the waste water from the module is directed to a control valve.

  • Patent number: 4501381
    Abstract: A coin-operated purified water dispensing machine. A pair of vertically stacked transparent fill tubes are mounted in a cabinet in visually exposed relation to a consumer operating the machine. A water dispensing nozzle is associated with each fill tube and is protected by a shroud that is specifically configured to engage the upper portion of a container to aid the consumer in properly positioning the container to be filled. The consumer activates the machine by placing the required coins in a coin chute. Acceptance of the coins effects rotation of a rotatably mounted cam that is fixedly secured to and in axial alignment with a four-way valve that in turn controls the flow of water into and out of the machine. The fill tubes are capped by end plug members having specific sealing and a piston is slidably mounted for reciprocating movement within each fill tube to effect vending of a precise volume of purified water.

  • Patent number: 4487420
    Abstract: A dart is described having a shaft to carry the flight, with a slot opening diametrically through the thickness of the shaft so that the flight can be deformed to a flat condition and pushed laterally through the slot, the extreme end of the shaft behind the flight being closed and pointed or rounded to provide a deflection surface in the event of contact by a further dart.

  • Patent number: 4473093
    Abstract: The valve, in the exemplary embodiment shown, comprises a gas inlet or intake valve for use with a gas compressor. It has a valve body with a gas inlet opening and a gas discharge opening, the latter for communication with the gas inlet of a compressor. A pair of concentrically-engaged pistons, relatively movable therebetween, cooperate to open, close, and throttle communication between the valve inlet and discharge openings. A first, compression spring, reactive from the valve body, urges the piston pair in a first closure disposition, to prevent gas flow through the valve body, and a second, compression spring, reactive from one of the pistons of the pair thereof, urges the other piston to a second, open disposition, to accommodate gas flow through the valve body.

  • Patent number: 4431390
    Abstract: The condensation control device includes sensors for measuring system pressure, ambient temperature and relative humidity for computing the saturation temperature of gas in the system. It also includes a sensor for sensing the system temperature which is compared with the saturation temperature to generate a signal that causes the opening of a valve in a by-pass conduit permitting cooling oil to by-pass a heat exchanger. Thus, the temperature in the compressor system is raised above the saturation temperature and avoids the formation of condensate in the system.

  • Patent number: 4263809
    Abstract: A test system for testing axles and wheel spindles directly in place on vehicles such as automobiles, which simplifies the loading to obtain the necessary information for testing axles and spindles using two sets of actuators, each set comprising a pair of actuators each operating to control loads on the spindle along two different orthogonal components of normal movement of the vehicle. The actuator arrangement saves space, permits testing without removing automotive sheet metal and simplifies the compensation factors necessary for controlling such systems.

  • Patent number: 3991477
    Abstract: A probe assembly is disclosed carrying a grid grating and an index grating adapted to generate a Moire pattern upon relative movement in either or both of two orthogonal directions in a common plane. The index and grid gratings are supported for precise orthogonal motion with respect to each other by means of a pair of grating support assemblies mounted so that the correct index and grid grating spacing and orientation are precisely maintained, including a cross-slide assembly provided to allow movement in a plane while maintaining the proper orientation between the grating assemblies.
