  • Publication number: 20020053613
    Abstract: A spray nozzle for producing an asymmetrically distributed fluid discharge pattern such as for use in a container coating application is provided. The spray nozzles includes a body portion having an internal fluid passageway which terminates in a substantially hemispherical dome shaped end wall. A discharge orifice is provided in the end wall which is produced by superimposing on each other an approximately round opening and an elongated opening having opposed rounded ends. The elongated opening having a length greater than a diameter of the round opening and the round opening and the elongated opening defining respective edges of the discharge orifice which extend at different angles relative to a longitudinal axis of the fluid passageway. The resulting orifice produces a fluid discharge pattern wherein the amount of fluid discharged tapers in a continuous, non-linear manner from the location of maximum discharge to points of minimum flow at either end of the discharge pattern.

  • Patent number: 6264890
    Abstract: A container is provided that is disposable, for first collecting blood delivered from a patient, preferably by a vacuum draw of blood into a container, and then the blood in the container is treated. The treatment is provided by an at least partial a back-and-forth or reciprocating motion of blood along membranes, such that filtrate components of the blood pass through the membrane walls and are collected, whereby retentate components of the blood are retained, with the back-and-forth motion being provided by a substantially constant vacuum draw, that provides a pumping action by a diaphragm pump. A replenishment liquid is automatically added, substantially proportional to the amount of filtrate components of the blood that are withdrawn. The membranes are protected by a device which removes body fat or other potentially harmful materials.

  • Patent number: 5810044
    Abstract: A system for controlling fluid flow from an outlet aperture, particularly a standpipe such as a fire hydrant. There is a first cylindrical collar element for location around the standpipe and connected with that element a second cylindrical element such that a space is defined between the two elements. There is a base provided between the two elements and a first outlet pipe for location above the standpipe. When the system is located about the standpipe fluid fills the space and stabilizes the elements relative to the standpipe. Fluid can then be directed away from the area of the aperture in the standpipe through the flexible pipe.

  • Patent number: 5789045
    Abstract: In the present invention, various sizes of non-wetting droplets are inserted into microtube devices of various shapes having therein a gas or wetting fluid which causes the droplets to movement in response to fluid pressure. The droplets may translate within a void of the microtube device which is filled with the gas or wetting fluid or rotate in a fixed position. The nonwetting fluid may also be formed into rings within ring shaped channels. The microtube devices may operate to stop fluid flow, act as a check-valve, act as a flow restrictor, act as a flow regulator, act as a support for a turning axle, and act as a logic device, for example.

  • Patent number: 5533668
    Abstract: A bi-directional airflow controllable system for controlling flow of air through an air circulating system to at least one zone an air temperature of which is to be controlled is coupled to an airflow duct to aid or oppose airflow throughout the duct and the system to the zone. The bi-directional airflow controllable system includes a fan positioned to interact with air moving through the system and the duct. The fan is coupled to a motor to be energized to drive the fan in a forward or reverse direction. The fan when driven by the energized motor in a forward direction creates air pressure from the fan to oppose the flow of air from the airflow duct. The fan when driven by the energized motor in a reverse direction aids the flow of air from the airflow duct. A bi-directional airflow control unit is electrically coupled to the motor.

  • Patent number: 5413278
    Abstract: The invention is directed to a method and apparatus for controlling airflow in a given direction in an air circulating system in which the method comprises the steps of:(a) placing a motor driven fan in the air circulating system in such a manner that the fan, when driven by the motor, creates pressure in a direction opposing the given direction of airflow, and(b) activating the motor to drive the fan to cause the airflow moving in said given direction to be diminished because of said opposing pressure.The apparatus is directed to an air flow controllable register for controlling a flow of air through the register from a register air flow supply duct in response to an externally provided control signal that commands differing airflow rates through the register. More specifically, the air flow controllable register includes a register flow control unit that includes a rotary mounted fan positioned within the register airflow supply duct. The fan is coupled to a motor.

  • Patent number: 4532949
    Abstract: An energy absorber for a high pressure and velocity fluid jet emanating from a nozzle is disclosed. An energy absorbing ball is freely rotatably supported in an energy absorbing chamber between seat faces. The high pressure and velocity fluid enters the energy absorbing zones and strikes the ball, causing it to rotate. The energy of the fluid is thereby substantially reduced. Since the ball is constantly in motion, a new surface is continually being brought into contact with the high energy fluid stream. This insures uniform wear of the ball as well as a long life. The ball and seats are disposed in a first end of a fluid flow conduit whose second end is carried in an adjustable support block which is in fluid communication with a fluid return line. The support block allows the spacing between the nozzle and the energy absorber to be varied to accommodate varying thicknesses of materials being cut by the high pressure fluid stream.

    Abstract: A method of forming a flat plate swing valve shell from a commercially available forged or swaged pressure vessel head having circular sections in horizontal planes and elliptic sections in vertical planes. The shell is formed by cutting the head along a vertical axis to form two halves, rotating the halves outwardly with respect to each other and repositioning them so their original base edges are juxtaposed and the two halves form a continuous enclosure having an open base and which has elliptic sections in both vertical and horizontal planes, and welding the two halves along said base edges to form a unitary valve shell.

  • Patent number: 4273156
    Abstract: The shutoff device for closing a large cross-sectional area gas duct comprises a lock chamber defined by the gas duct walls and the two rows of swivel louvre grills held to the housing of the shutoff device which accommodates also a mechanical actuator, said louvre grills being arranged in the gas duct at an angle to the vertical plane in such a manner as to be spaced more widely apart in the top portion of the gas duct than in the bottom portion thereof. When the gas duct is being closed the lock chamber is filled with bulk free-flowing material from the top hopper located in the gas dust upper portion, whereas when the gas duct is being opened, the lock chamber is emptied of said bulk material, which is free to pour by gravity into the bottom receiving hopper, both of said hoppers being interconnected through a conveyer for the bulk material to return to the top hopper.
