  • Patent number: 10697879
    Abstract: A method and system of measuring the size distribution of particles within dilute colloids, for example, through variation of the minimum detected size of aerosolized colloid particles. The method of determining the size distribution of particles in a fluid, involves forming a stream of aerosol droplets of the fluid, the droplets containing particles and dissolved material evaporating the droplets to generate particles, and measuring the concentration of particles by varying a detection threshold. A system or apparatus for determining the size distribution of particles in a fluid, includes a droplet former for forming a stream, of aerosol droplets of the fluid, the droplets containing particles and dissolved material, and a condensation particle detector for evaporating the droplets to generate particles and for measuring the concentration of particles, the condensation particle detector having a variable detection threshold.

  • Patent number: 10650934
    Abstract: An insulated solution injector may include an outer tube and an inner tube arranged within the outer tube. The outer tube and the inner tube may define an annular space therebetween, and the inner tube may define a solution space within. The annular space may be configured so as to insulate the solution within the solution space. As a result, the solution may be kept to a temperature below its decomposition temperature prior to injection. Accordingly, the decomposition of the solution and the resulting deposition of its constituents within the solution space may be reduced or prevented, thereby decreasing or precluding the occurrence of a blockage.

    Abstract: One or more embodiments of the present invention are directed to a vertical microfluidic probe head, which comprises a middle layer of material and two outer layers. The middle layer comprises two opposite, main surfaces, which are, each, grooved up to a same edge surface that adjoins each of the main surfaces, so as to form two sets of n microchannel cavities, n?1, on each of the opposite main surfaces. The middle layer is furthermore arranged between the two outer layers, which (at least partly) close the microchannel cavities grooved on the two main surfaces. This way, two sets of n microchannels are formed, which are, each, open on the edge surface, such that two opposite sets of n orifices are formed on the edge surface. Thus, the length of the apertures is not limited by the thickness of the middle layer.

The system includes a labyrinth seal ring comprising a series of knives defining first and second labyrinth paths from an air inlet to the process side and the bearing side of the system, respectively. The differences in the two paths such as provided by the number of knives used in each path creates a differential pressure drop which biases air from the air inlet to the process side.

    Abstract: A fluid processing apparatus for processing a material to be processed between processing surfaces of processing members capable of approaching to and separating from each other, so as to rotate relative to each other, introduces a first fluid between the processing surfaces, introduces a second fluid between the processing surfaces from another flow path independent of the first fluid, and mixes and stirs the first and second fluids between the processing surfaces to undergo treatment. A processing member is composed by assembling a plurality of divided components of the processing member. An opening and a flow path are formed in the space between the plurality of components. This eliminates the need to create all ring-shaped disks which are the processing member as one block, and also eliminates the need to substantially process the flow path leading to the opening, thereby making it possible to easily undergo decomposition and cleaning.

  • Patent number: 8870085
    Abstract: A hot and cold water mixing valve including a temperature adjusting dial, and a cylindrical casing having formed therein a hot water inlet and a cold water inlet is provided with a control valve member in which one end thereof is subjected to a load from a biasing member and the other end is subjected to a load from an actuator. By balancing between the loads applied by the biasing member and the actuator, a mixture ratio between the hot water which flows in through the hot water inlet and the cold water which flows in through the cold water inlet is adjusted. A temperature adjuster adjusts a position of the control valve member through the biasing member and includes a tapered skirt portion, which spreads in a radial direction, at an end on the control valve member side thereof.

  • Publication number: 20140196807
    Abstract: An injecting machine for two different liquids is configured to inject a liquid mixture of the two different liquids in a first-in first-out manner. The liquid mixture passes from a passage of an injection cylinder through a helical groove of a plunger into a forward space formed forwardly of the plunger as the plunger gradually moves back. When the plunger reaches a fully retracted position, a first part of the mixture remains in a front portion of the forward space while a last part of the mixture remains in a rear portion of the forward space. As the plunger moves to an advanced position, the first part of the mixture is first injected out of a nozzle and the last part of the mixture is finally injected out of the nozzle.

    Abstract: A method and system for boosting pipeline gas pressure in a low-pressure gas pipeline in which a supplemental gas supply pipe in fluid communication with a supplemental pipeline gas supply is provided to an interior of a gas pipeline containing a pressurized pipeline gas, where the pressure of the supplemental pipeline gas supply is greater than the pressure of the pressurized pipeline gas. The gas pressure differential between the pressurized pipeline gas and the supplemental pipeline gas supply pressure is measured. When the pressure differential reaches a certain predetermined set value, supplemental pipeline gas is provided from the supplemental pipeline gas supply through the supplemental gas supply pipe into a pipeline space between the gas pipeline and the supplemental gas supply pipe. The flow of supplemental pipeline gas is halted upon achievement of a second predetermined set differential pressure.

    Abstract: A gas mixing device has a plurality of interleaved rows of adjustable louvers. When at least two flowing gas streams are received that are desired to be mixed, the louvers of each row directs the gas streams in a direction different from that of the adjacent rows, mixing the gas streams. When effectively only a single flowing gas stream is received, the louvers are positioned vertically thereby reducing the pressure drop across the gas mixing device.
