US Patent:

42022118, May 13, 1980

Filed:

Jan 12, 1979

Appl. No.:

6/003074

Inventors:

Jack A. Perry - Lewiston NY

Assignee:

NP Industries, Inc. - Niagara Falls NY

International Classification:

G01F 100

US Classification:

73227

Abstract:

In order to enable measurement of liquid flow through channels noninvasively without contact or interference with the flow through the channel, detectors of liquid level and velocity through the channel are installed above and below the channel and transmit and receive only ultrasonic signals. A flow measuring system is operated by their detectors and measures flow in terms of the product of the area through which the liquid flows and its velocity.

Assignee:

Q Jet DSI, Inc. - North Haven CT

International Classification:

B01F 304

US Classification:

261 62

Abstract:

A fluid mixing apparatus for mixing a first fluid with a second fluid and to prevent acoustic hammer effects, utilizing a condensing tube array. In accordance with one embodiment of the invention, a direct steam injection process heater is provided, having a first body for introducing a first fluid, generally a liquid or slurry, a second body for introducing a second fluid, generally steam, an orifice plate disposed between the two bodies, and a valve member for movement to and away from the orifice plate. The orifice plate has a plurality of frusto-conical holes which are engaged preferably by an equal number of complementary-configured, conically-tipped pins mounted onto the valve member. An actuator moves the valve member relative to the orifice plate such that the pins penetrate and partially or wholly obscure the holes, thus regulating the flow of the second fluid through the holes. The mixing area of the first body is equipped with a condensing tube array, having a plurality of condensing tubes rigidly secured in relation to each other by a plurality of retaining rings and secured in the first body by a plurality of studs.

International Classification:

B01F 1502

US Classification:

3661632

Abstract:

A fluid mixing apparatus for mixing a first fluid with a second fluid is provided. The fluid mixing apparatus includes a first housing, a second housing, a first actuator corresponding with the first housing, and a second actuator corresponding with the second housing. The first housing is provided with an inlet for supplying a first fluid such as water in the form of steam, and a nozzle outlet attached to a nozzle end of the first housing. The second housing is coupled to the nozzle end of the first housing and includes a inlet for supplying a second fluid such a slurry. A mixing tube, which may be slidable, is contained within the second housing for mixing the first fluid and the second fluid therein before passing the mixture out of the second housing. Alternatively, collar member may be circumferentially mounted around a stationary mixing tube contained in the second housing, or alternatively, around the nozzle outlet of the first housing. Depending upon whether the mixing tube is slidable, or where collar member is mounted if utilizing a stationary mixing tube, a circumferential gap is created between nozzle outlet and the collar member when the collar member is mounted on the mixing tube, and between the mixing tube and the collar member when the collar member is mounted on the nozzle outlet.

Inventors:

Jack A. Perry - Lewiston NY

International Classification:

G01N 110

US Classification:

73422TC

Abstract:

A pressure rise tube sampler for sampling liquid flowing in a conduit under high pressure including a pressure rise tube, a side arm sampler in communication with the rise tube, a first valve arrangement for permitting high pressure liquid to enter the rise tube from a high pressure liquid conduit, a liquid level control for closing the first valve arrangement after the liquid level in the rise tube has exceeded the level of the side arm and for opening a second valve arrangement to permit the liquid to be forced from the rise tube by the air which it compressed in entering the rise tube, and a third valve arrangement in the side arm for permitting liquid to be discharged therefrom into a container for analysis purposes.

International Classification:

G01N 114

US Classification:

73422R

Abstract:

A liquid sampler including a force main sampling chamber, a seal leg having an end portion immersed in liquid in said sampling chamber, a dam in the sampling chamber for maintaining the liquid at a predetermined minimum elevation therein, a draw tube in communication with the seal leg, a pump for supplying either compressed air or vacuum to the draw tube, first control means for causing the pump to supply vacuum to the draw tube only when a sample is to be taken, a side arm in the draw tube for receiving liquid, second control means including non-contact liquid-level sensing means in the draw tube for causing the pump to supply pressure rather than vacuum after the liquid reaches a predetermined level in the draw tube, and circuit means for terminating operation of the sampling cycle in the event a sample is not taken within a predetermined time period after the sampling cycle is initiated.
